High-temperature magnetic drive pumps are compact, aesthetically pleasing, small in size, and feature stable, user-friendly operation with low noise levels. They are widely used in chemical, pharmaceutical, petroleum, electroplating, food, film processing, scientific research institutions, defense industries, and other sectors for pumping acids, alkaline solutions, oils, rare and valuable liquids, toxic liquids, volatile liquids, and in circulating water equipment, as well as for supporting high-speed machinery. They are particularly suitable for liquids that are prone to leakage, evaporation, combustion, or explosion. It is best to choose an explosion-proof motor for such pumps.

Advantages of High-Temperature Magnetic Drive Pumps:

1. No need to install a foot valve or prime the pump.

2. The pump shaft is changed from dynamic sealing to enclosed static sealing, completely avoiding media leakage.

3. No independent lubrication or cooling water is required, reducing energy consumption.

4. Power transmission is changed from coupling drive to synchronous dragging, eliminating contact and friction. This results in low power consumption, high efficiency, and provides damping and vibration reduction, minimizing the impact of motor vibration on the pump and pump cavitation vibration on the motor.

5. In case of overload, the inner and outer magnetic rotors slip relative to each other, protecting the motor and pump.

6. If the driven component of the magnetic drive operates under overload conditions or the rotor jams, the driving and driven components of the magnetic drive will automatically slip, protecting the pump. Under these conditions, the permanent magnets in the magnetic drive will experience eddy current losses and magnetic losses due to the alternating magnetic field of the driving rotor, causing the temperature of the permanent magnets to rise and leading to the failure of the magnetic drive slip.

Precautions for Using High-Temperature Magnetic Drive Pumps:

1. Prevent Particle Entry

(1) Do not allow ferromagnetic impurities or particles to enter the magnetic drive or the bearing friction pair.

(2) After transporting media prone to crystallization or sedimentation, flush promptly (fill the pump cavity with clean water after stopping the pump, run for 1 minute, then drain completely) to ensure the service life of the sliding bearings.

(3) When pumping media containing solid particles, install a filter at the pump inlet.

2. Prevent Demagnetization

(1) The magnetic torque must not be designed too small.

(2) Operate within the specified temperature conditions; strictly avoid exceeding the maximum allowable media temperature. A platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve to monitor the temperature rise in the gap area, enabling an alarm or shutdown if the temperature limit is exceeded.

3. Prevent Dry Running

(1) Strictly prohibit dry running (operating without liquid).

(2) Strictly avoid running the pump dry or allowing the media to be completely drained (cavitation).

(3) Do not operate the pump continuously for more than 2 minutes with the discharge valve closed, to prevent overheating and failure of the magnetic drive.

4. Not for Use in Pressurized Systems:​

Due to the existence of certain clearances in the pump cavity and the use of "static bearings," this series of pumps must absolutely not be used in pressurized systems (neither positive pressure nor vacuum/negative pressure is acceptable).

5. Timely Cleaning:​

For media that are prone to sedimentation or crystallization, clean the pump promptly after use and drain any residual liquid from the pump.

6. Regular Inspection:​

After 1000 hours of normal operation, disassemble and inspect the wear of the bearings and the end face dynamic ring. Replace any worn-out vulnerable parts that are no longer suitable for use.

7. Inlet Filtration:​

If the pumped medium contains solid particles, install a strainer at the pump inlet. If it contains ferromagnetic particles, a magnetic filter is required.

8. Operating Environment:​

The ambient temperature during pump operation should be less than 40°C, and the motor temperature rise should not exceed 75°C.

9. Media and Temperature Limits:​

The pumped medium and its temperature must be within the allowable range of the pump materials. For engineering plastic pumps, the temperature should be <60°C; for metal pumps, <100°C. The suction pressure should not exceed 0.2MPa, the maximum working pressure is 1.6MPa, for liquids with a density not greater than 1600 kg/m³ and a viscosity not greater than 30 x 10⁻⁶ m²/s, and which do not contain hard particles or fibers.

High-temperature magnetic drive pumps replace dynamic seals with static seals, making the pump's wetted parts fully enclosed. This solves the unavoidable running, dripping, and leaking issues associated with the mechanical seals of other pumps. Manufactured using highly corrosion-resistant materials such as engineering plastics, alumina ceramics, and stainless steel, these pumps offer excellent corrosion resistance and ensure the pumped media remains uncontaminated.

Stainless steel submersible pumps are widely used in drainage applications across industries such as pharmaceuticals, environmental protection, food, chemical, and power due to their characteristics of corrosion resistance, hygiene, energy efficiency, environmental friendliness, non-clogging, high flow rate, and strong passage capability. Anhui Shengshi Datang will study together with everyone.

I. Common Causes and Solutions for Insufficient Flow or No Water Output in Stainless Steel Submersible Pumps:

1. The installation height of the pump is too high, resulting in insufficient impeller immersion depth and reduced water output. Control the allowable deviation of the installation elevation and avoid arbitrary adjustments.

2. The pump rotates in the reverse direction. Before trial operation, run the motor without load to ensure the rotation direction matches the pump. If this occurs during operation, check whether the power phase sequence has changed.

3. The outlet valve cannot open. Inspect the valve and perform regular maintenance.

4. The outlet pipeline is blocked, or the impeller is clogged. Clear blockages in the pipeline and impeller, and regularly remove debris from the reservoir.

5. The lower wear ring of the pump is severely worn or blocked by debris. Clean the debris or replace the wear ring.

6. The density or viscosity of the pumped liquid is too high. Identify the cause of the change in liquid properties and address it.

7. The impeller is detached or damaged. Reinforce or replace the impeller.

8. When multiple pumps share a common discharge pipeline, a check valve is not installed or the check valve is not sealing properly. Install or replace the check valve after inspection.

II. Causes of Abnormal Vibration and Instability During Operation of Stainless Steel Submersible Pumps:

1. The anchor bolts of the pump base are not tightened or have become loose. Tighten all anchor bolts evenly.

2. The outlet pipeline lacks independent support, causing pipeline vibration to affect the pump. Provide independent and stable support for the outlet pipeline, ensuring the pump’s outlet flange does not bear weight.

3. The impeller is unbalanced, damaged, or loosely installed. Repair or replace the impeller.

4. The upper or lower bearings of the pump are damaged. Replace the bearings.

III. Causes of Overcurrent, Motor Overload, or Overheating in Stainless Steel Submersible Pumps:

1. The operating voltage is too low or too high. Check the power supply voltage and adjust it.

2. There is friction between rotating and stationary parts inside the pump, or between the impeller and the seal ring. Identify the location of the friction and resolve the issue.

3. Low head and high flow cause a mismatch between the motor power and the pump characteristics. Adjust the valve to reduce the flow, ensuring the motor power matches the pump.

4. The pumped liquid has high density or viscosity. Investigate the cause of the change in liquid properties and adjust the pump’s operating conditions.

5. The bearings are damaged. Replace the bearings at both ends of the motor.

IV. Causes and Solutions for Low Insulation Resistance in Stainless Steel Submersible Pumps:

1. The cable ends were submerged during installation, or the power or signal cable was damaged, allowing water ingress. Replace the cable or signal wire, and dry the motor.

2. The mechanical seal is worn or not properly installed. Replace the upper and lower mechanical seals, and dry the motor.

3. The O-rings have aged and lost their function. Replace all sealing rings and dry the motor.

V. Causes and Solutions for Visible Water Leakage in Pipes or Flange Connections of Stainless Steel Submersible Pump Systems:

1. The pipeline itself has defects and was not pressure-tested.

2. The gasket connection at the flange joint was not properly handled.

3. The flange bolts were not tightened correctly. Repair or replace defective pipes, realign misaligned pipes, and ensure bolts are inserted and tightened freely. After installation, conduct a pressure and leakage test on the entire system. Replace components as necessary.

VI. Internal Leakage in Stainless Steel Submersible Pumps:

Leakage in the pump can lead to insulation failure, bearing damage, alarm activation, and forced shutdown. The main causes include failure of dynamic seals (mechanical seals) or static seals (cable inlet seals, O-rings), and damage to power or signal cables allowing water ingress. Alarms such as water immersion, leakage, or humidity may trigger shutdowns. Before installation, inspect the quality of all sealing components. Ensure proper contact between sealing surfaces during installation. Before operation, check the motor’s phase-to-phase and ground insulation resistance, and ensure all alarm sensors are functional. If leakage occurs during operation, replace all damaged seals and cables, and dry the motor. Do not reuse disassembled seals or cables.

VII. Reverse Rotation After Shutdown of Stainless Steel Submersible Pumps:

1. Reverse rotation occurs after the pump motor is powered off, mainly due to failure of the check valve or flap valve in the outlet pipeline.

2. Before installation, inspect the check valve for correct orientation and ensure the flap valve is centered and operates flexibly. Regularly inspect the check valve or flap valve during operation, and repair or replace damaged components with quality parts.

Fluoroplastic self-priming pumps, also known as the TIZF series fluoroplastic self-priming pumps, are designed and manufactured in accordance with international standards and the manufacturing processes for non-metallic pumps. The pump structure adopts a self-priming design. The pump casing consists of a metal shell lined with fluoroplastic, and all wetted parts are made of fluoroplastic alloy. Components like the pump cover and impeller are manufactured by integrally sintering and pressing metal inserts coated with fluoroplastic. The shaft seal utilizes an advanced external bellows mechanical seal. The stationary ring is made of 99.9% alumina ceramic (or silicon nitride), and the rotating ring is made of PTFE-filled material, ensuring highly stable corrosion resistance, wear resistance, and sealing performance.

A fluoroplastic self-priming pump does not require priming before startup (although the initial installation still requires priming). After a short period of operation, the pump can draw fluid up and commence normal operation through its own action.

Fluoroplastic self-priming pumps can be classified by their operating principle into the following categories:

1.Gas-liquid mixing type (including internal mixing and external mixing).

2.Water ring type.

3.Jet type (including liquid jet and gas jet).

Working process of the gas-liquid mixing self-priming pump: Due to the special structure of the pump casing, a certain amount of water remains in the pump after it stops. When the pump is started again, the rotation of the impeller fully mixes the air in the suction line with the water. This mixture is discharged into the gas-water separation chamber. The gas in the upper part of the separation chamber escapes, while the water in the lower part returns to the impeller to mix again with the remaining air in the suction line. This process continues until all gas in the pump and suction line is expelled, completing the self-priming process and allowing normal pumping.

Water ring self-priming pumps​ integrate a water ring and the pump impeller within a single housing, using the water ring to expel gas and achieve self-priming. Once the pump operates normally, the passage between the water ring and the impeller can be closed off via a valve, and the liquid within the water ring can be drained.

Jet self-priming pumps: consist of a centrifugal pump combined with a jet pump (or ejector). They rely on the ejector device to create a vacuum at the nozzle to achieve suction.

The self-priming height of a fluoroplastic self-priming pump is related to factors such as the front impeller seal clearance, pump speed, and liquid level height in the separation chamber. A smaller front impeller seal clearance results in a greater self-priming height, typically set between 0.3-0.5 mm. If the clearance increases, besides a decrease in self-priming height, the pump's head and efficiency also reduce. The self-priming height increases with the rise in the impeller's peripheral velocity (u2). However, once the maximum self-priming height is reached, further speed increases will not raise the height but only shorten the priming time. If the speed decreases, the self-priming height also decreases. Under other constant conditions, the self-priming height increases with a higher stored water level (but should not exceed the optimal water level for the separation chamber).

To better facilitate gas-liquid mixing within the self-priming pump, the impeller should have fewer blades, increasing the pitch of the blade grid. It is also advisable to use a semi-open impeller (or an impeller with wider flow channels), as this allows the returning water to penetrate more deeply into the impeller blade grid.

Most fluoroplastic self-priming pumps are matched with internal combustion engines and mounted on movable carts, making them suitable for field operations.

What is the working principle of a fluoroplastic self-priming pump?

For a standard centrifugal pump, if the suction liquid level is below the impeller, it must be primed with water before startup, which is inconvenient. To retain water in the pump, a foot valve is required at the inlet of the suction pipe, but this valve causes significant hydraulic losses during operation.

A self-priming pump, as described above, does not require priming before startup (except for the initial installation). After a short operation, it can draw fluid up and begin normal operation. The classification and working principles of the different self-priming types (gas-liquid mixing, water ring, jet) are as previously detailed.

Fabric Ici Mace Snag Testing is an important method for assessing the snag resistance of knitted fabrics and some woven fabrics. It is widely used in quality control, product development, and standard compliance testing in the textile industry. The following is an introduction to its working principle, structural components, technical parameters, operating methods, maintenance, and other aspects:

1. Core standards:

GB/T 11047-2008 ‘Textiles — Evaluation of fabric snagging properties — Hammer test method’

ISO 13935-1:2019 ‘Textiles — Determination of fabric snagging properties — Part 1: Hammer test method’

ASTM D3939 (American Society for Testing and Materials standard), etc.

2. Applicable fabrics

Mainly applicable to knitted fabrics (such as underwear, sweaters, sportswear fabrics, etc.), it can also be used for some woven fabrics that are prone to snagging (such as lightweight synthetic fabrics). The focus is on evaluating the fabric's resistance to friction and snagging during daily use, which can cause fibres to be pulled out and form loops or pilling.

3.Working Principle: A package of beads with a known weight is placed into the knitted fabric sample, which is then inserted into a test drum equipped with needle rods. The test drum rotates at a specified speed, causing the knitted fabric and bead pillows to tumble and friction within the drum, simulating the snagging conditions the fabric may encounter during actual use. After a predetermined number of revolutions, the test is stopped, the sample is removed, and the fabric's snagging grade is evaluated according to relevant standards.

4. Structural Components  

Drive system: motor and transmission device to control the rotation of the specimen cylinder.

Sample cylinder: Smooth-surfaced, removable cylindrical cylinder for wrapping and fixing the fabric sample to be tested. The standard diameter is usually 92±1mm.

Bead Pillow (Staple Hammer/Puncture Roller): The core component. Usually a cylinder with stainless steel pins or nails of a specific specification (e.g. diameter, length, number, arrangement) regularly set on the surface. Its weight is an important parameter for testing (e.g. 2.5kg is a common standard requirement). Some instruments may be equipped with bead pillows of different sizes.

Weights (optional): used to accurately regulate the total pressure applied to the bead cushion (weight of the cushion + additional weights).

Counter: Records the number of revolutions (RPM) of the specimen cylinder.

Protective cover: prevents the bead cushion from accidentally flying or spilling of sample fragments during the test for safety.

Base and Frame: Supports the entire structure of the instrument.

5. Technical Specifications  

Test Speed: Typically 20±3 rpm.  

Power Supply Voltage: AC 220V ±10%, power approximately 60W.  

Dimensions: Vary by model, e.g., 470×420×390 mm or 47×38×38 cm, etc.

6. Operating Procedures  

Preparation: Select appropriate knitted fabric samples, ensure the sample dimensions meet requirements, and prepare bead pillows of qualified weight. Connect the power supply and check if the instrument is operating normally.  

Sample Installation: Place the bead pillow into the knitted fabric sample, then secure the sample with the bead pillow in the sample clamp, and insert the sample clamp into the test drum.

Parameter Settings: Set the test drum's rotation speed, RPM, and other parameters according to the test standards and requirements.  

Start Test: Activate the instrument, and the test drum begins rotating. The knitted fabric and bead pillow roll and friction within the drum to conduct the pilling test.  

Test Completion: When the counter displays the predetermined rotation count, the instrument automatically stops. Remove the sample and evaluate its pilling grade according to relevant standards.

7. Maintenance and Care  

Regular Cleaning: Regularly clean the test drum, needle rod, and fabric debris, dust, and other contaminants from the needles to maintain the cleanliness of the instrument’s interior and prevent interference with test results.  

Inspect Components: Regularly inspect components such as the needle rod, needles, and sample clamps for damage, deformation, or loosening. If any issues are found, promptly replace or repair them to ensure the instrument operates normally.

Instrument Calibration: Calibrate the instrument regularly in accordance with the manufacturer's recommendations and relevant standards to ensure the accuracy and reliability of test results.

Proper Storage: When not in use, store the instrument in a dry, well-ventilated environment to prevent moisture, rust, or other damage.

Salt spray test, as an important means of assessing the salt spray corrosion resistance of products or metal materials, the determination of the test results is not only directly related to the judgment of product quality, but also affects the subsequent research and development and production decisions. Salt spray test results determination of the four main methods: rating determination method, weighing determination method, corrosive material appearance determination method and corrosion data statistical analysis method.

1. Rating and judgment method

Rating judgment method, is the corrosion area and the total area of the sample ratio of the percentage in accordance with certain standards into a number of grades, to a particular grade as a qualified or unqualified basis for judgment. This method is particularly suitable for the evaluation of flat samples, because it can visually reflect the degree of corrosion of the sample surface.

2.Weighing judgment method

Weighing judgment method is through the measurement of corrosion test before and after the change in the quality of the sample, calculate the weight of the corrosion loss (or weight gain), in order to judge the corrosion resistance of the sample quality. This method is particularly suitable for accurate assessment of the corrosion resistance of metal materials.

3.The appearance of corrosive material judgment method

Corrosive appearance determination method is a qualitative determination method, which is based on the salt spray corrosion test whether the product produces visible corrosion phenomenon to judge the corrosion resistance of the sample. This method is simple and intuitive, easy to operate, so it is widely used in many product standards.

4. Corrosion data statistical analysis

Statistical analysis of corrosion data is a more complex and comprehensive determination method, which combines the test design, data collection, statistical analysis and other aspects of the design of corrosion tests, analysis of corrosion data, corrosion data to determine the confidence level of the scientific method.

5. Comprehensive application

In practical application, these four determination methods often do not exist in isolation, but according to specific needs and test conditions for flexible selection and combination. For example, in the evaluation of the corrosion resistance of flat plate samples, you can prioritize the use of rating determination method and weighing determination method; and in the assessment of complex shapes or surface treatment of uneven samples, can be combined with the emergence of corrosive material determination method and statistical analysis of corrosion data for a comprehensive judgment.

Reminder: A clean workspace helps you spot leaks and problems early. Always keep cleaning supplies nearby.

Remove Hydraulic Cylinders

Depressurize and Secure Equipment

You must make sure the equipment is safe before you start. High pressure hydraulic cylinders can keep high pressure inside, even when off. You need to do these steps to stay safe:

1. Take out all pressure from the hydraulic system. Lock out the pressure first. Even small hydraulic cylinders can hold a lot of PSI. Always check that all pressure is gone before you go on.

2. Make sure everyone has the right training. This helps stop accidents from happening.

3. Follow the instructions from the manufacturer. These steps help you avoid mistakes.

4. Use the correct tools for the job. Special tools keep you safe and protect the equipment.

5. Make the machine steady and safe. Use latches or blocks to hold it still.

6. Lower any loads onto mechanical locks. This takes pressure off the system.

7. Turn off the hydraulic pump and close the shut-off valve. This stops fluid from moving while you work.

8. Disconnect all energy sources. Get rid of any stored energy so the machine does not start by accident.

Tip: Always check again that the system has no pressure before you touch any hydraulic cylinders.

Disconnect and Plug Hydraulic Lines

After you make the equipment safe, you need to disconnect the hydraulic lines. This step helps stop leaks and keeps dirt out. Do these steps:

1. Turn off and depressurize the system. Make sure the power is off and pressure is gone. Use gauges to check for leftover pressure.

2. Clean around the coupler. Wipe away dirt or fluid. This keeps the inside clean.

3. Unlock the coupler. Release it based on its type. Make sure no pressure is left.

4. Cap and seal the ends right away. Put dust caps and plugs on both ends to stop dirt from getting in.

You can use different plugs or caps for hydraulic ports. The table below shows some common types and what they are used for:

Note: Always plug open ports right after you disconnect a line. This stops leaks and keeps dirt out.

Remove Cylinder and Drain Fluid

Now you can take out the hydraulic cylinder. Be careful and drain the fluid to stop spills. Here is what you do:

1. Make sure all hydraulic cylinders are closed. This leaves less oil inside.

2. Find the drain ports. Start with the main reservoir to drain faster.

3. Take out any return-line filters. This lets more fluid drain from the return lines.

4. Put a container under the hydraulic cylinder. This catches any fluid left inside.

5. Let the hydraulic fluid drain all the way. Wait until no more fluid comes out.

Safety Alert: Hydraulic cylinders can be heavy and hard to move. Use lifting tools or ask for help if you need it. Hold the cylinder with blocks or straps so it does not fall or roll.

When you change hydraulic cylinders, always clean the unit before you take it out. Plug all ports to stop leaks. Drain all fluid before you move the cylinder. These steps keep you safe and help the system work well.

Install Hydraulic Cylinders

Inspect and Prepare New Cylinder

Before you install the new cylinder, you need to check everything carefully. Safety comes first. You must wear gloves, goggles, and steel-toed boots. Look at the area where you will work. Make sure it is clean and safe. You should clean the hydraulic system and check the fluid level. Look at the new hydraulic cylinder for any damage or defects. Make sure it is the right size and has the correct mounting points. Secure the machine so it does not move while you work.

Here is a simple checklist to help you prepare the new cylinder:

1. Put on your safety gear.

2. Clean the work area and remove any debris.

3. Check the hydraulic fluid level and quality.

4. Inspect the new hydraulic cylinder for cracks, dents, or missing parts.

5. Confirm the cylinder matches the machine’s requirements.

6. Lock the machine in place to prevent movement.

Tip: Always double-check the mounting points and seals before you begin. This helps prevent leaks and future problems.

Position and Secure Cylinder

You need to position the new heavy duty hydraulic cylinder with care. Sometimes, the cylinder is heavy or hard to reach. You can use a cable winch to help move and extend the cylinder into place. Make sure the winch can handle the weight. Check the cable for strength and look for an emergency shut-off switch. Always use solid support under the cylinder and crib your load for safety.

• Use only 80% of the winch’s rated load and stroke for stability.

• Always use a saddle to protect the plunger and spread the load.

• Place the cylinder on a flat, clean surface.

• Use a pressure gauge to monitor levels.

When you position the cylinder, alignment is very important. If the cylinder is not straight, it can wear out quickly or break. You should measure and align the mounting brackets on both ends. Make sure they are parallel and level. Fasten the brackets with bolts or pins. Prepare the mounting surface so it is smooth and clean. Use a level or laser device to align the cylinder with the load and hydraulic system.

"If a slight misalignment cannot be avoided then the use of a spherical rod eye attachment may be required to compensate. Side loads can be caused by bent or twisted structures, which result in the pivot points of the cylinder no longer being on a parallel plane."

Proper alignment helps prevent stress and damage. You should also check the ports and hoses to make sure they do not twist or kink.

Reconnect Lines and Refill Fluid

After you install the new cylinder, you need to reconnect the hydraulic lines and fill with hydraulic fluid. Replace all the lines and test for leaks around the new seals. Make sure the fluid level is correct after refilling.

You should tighten all connections and check for drips. Watch the pressure gauge as you refill the system. If you see any leaks, stop and fix them before you continue.

Note: Always use clean hydraulic fluid. Dirty fluid can damage the new hydraulic cylinder and cause problems in the system.

You have now finished the main steps to install hydraulic cylinders. Careful inspection, proper alignment, and secure mounting help your equipment work safely and last longer.
