The maintenance methods of screen printing machines
2026-01-14
The maintenance methods of screen printing machines include:
daily maintenance, long-term maintenance, regular inspection and maintenance, and cleaning and maintenance steps.
Daily maintenance Before operating the screen printing machine, the operator should first check whether there is dust left by chips at the junction of the movable guide rail surface of the screen printing machine, and keep it free of oil stains, brushing, scratches and other phenomena
2. If the screen printing machine is not used for a long time, it should be wiped clean and placed in a cool, dry environment with good ventilation effect
3. Experienced operators should not disassemble the touch screen without the guidance of a professional master, because it is easy to damage the touch screen. Operators must regularly conduct condition surveys, accuracy inspections, and adjustments of screen printing machine equipment, and carry out fault analysis and condition monitoring
4. In the daily maintenance of the screen printing machine, it is strictly forbidden for the operator to disassemble the parts, and when the screen printing machine fails, the emergency stop switch must be pressed immediately and the main power supply must be turned off, and the maintenance personnel must be notified.
Cleaning and maintenance steps: Cleaning of the walking arm: first remove the cover, then check whether there are any debris on the walking arm track, clean up the debris with a duster, then use a brush to clean the debris in the gap, then scrub the track with an alcohol-free dust cloth, and then add some track oil to the track
5. Inspection of servo motor: manually control the motor movement, observe whether the motor movement is stable, touch the motor to see if there is heat, long-term movement will lead to loose transmission shaft connection, if necessary, adjust the motor PID parameters and adjust the level; Check whether the connecting belt of the motor is loose and broken, and adjust it if necessary
The working principle of the screen printing machine
2026-01-14
The working principle of the screen printing machine ① The working cycle program of the flat screen flat screen printing machine takes the flat screen platform type monochrome semi-automatic hand screen printing machine as an example. One of its working cycles is: feeding parts → positioning → printing → Lower the squeegee, raise the ink return plate → Squeegee stroke → Raise the squeegee → Lower the ink return plate → Lift the plate → Return ink stroke → Release positioning → Receiving.
In the continuous cycle action, as long as the function can be realized, the time occupied by each action should be as short as possible to shorten the period of each work cycle and improve the work efficiency.
③ Embossing line. During the printing stroke, the squeegee squeezes the ink and the screen printing plate, so that the screen printing plate and the substrate form a contact line, which is called a nip line. This line is at the edge of the squeegee, and countless embossed lines form the printing surface. Achieving an ideal nip line is difficult because the printing stroke is a dynamic process.
③The working principle of screen printing machine. Taking the commonly used hand-shaped screen printing machine as an example, the working principle of the screen printing machine can be described as follows: the power is transmitted through the transmission mechanism, and the squeegee squeezes the ink and the screen printing plate during the movement, so that the screen printing The printing plate and the substrate form an embossing line. Since the screen has tensions N1 and N2, a force F2 is generated on the squeegee. Under the action of the squeezing force F1 of the squeegee, through the mesh, the printing is missed from the moving embossing line to the substrate.
During the printing process, the screen printing plate and the squeegee move relative to each other, and the extrusion force F1 and the rebound force F2 also move synchronously. Dirty blots. That is, the screen is constantly deformed and rebounded during the printing stroke.
The squeegee is separated from the substrate together with the screen printing plate after the one-way printing is completed, and at the same time, the ink is returned to the back, that is, a printing cycle is completed. The distance between the top of the substrate and the reverse side of the screen printing plate after returning to ink is called the same plate distance or screen distance, which should generally be 2 to 5 mm. In manual printing, the operator's technique and proficiency directly affect the formation of the embossing line. In practice, screen printing workers have accumulated a lot of valuable experience, which can be summarized into six points, that is, to ensure the linearity, uniformity, isometric, pressure equalization, centering and verticality in the movement of the squeegee. That is to say, the squeegee should move in a straight line during printing, and it should not be shaken left and right; it should not be slow forward and fast, fast forward and then slow or suddenly slow and fast; the inclination angle to the ink plate should remain unchanged, and special attention should be paid to overcoming the inclination angle. A common problem that gradually increases; the printing pressure should be kept uniform; the distance between the squeegee and the inner side of the screen frame should be equal; the ink plate and the frame should be kept perpendicular
How Do Low-Temperature Air-Cooled Chillers Achieve Effective Heat Recovery
2026-01-14
In modern industrial and building applications, the energy consumption of low-temperature air-cooled chillers is a growing concern. Recovering waste heat from these systems can significantly improve overall energy efficiency while reducing operational costs and environmental impact. So, how exactly does heat recovery work in these systems?
1. Using High-Efficiency Heat Exchangers
A key method for heat recovery is integrating high-efficiency heat exchangers into the chiller system.When the air-cooled chiller releases waste heat, this thermal energy is transferred to a secondary medium—such as water or air—inside the heat exchanger. The recovered heat can then be reused for:
• Preheating fresh air
• Supplying domestic hot water
• Industrial process heating
By using counter-flow heat exchange, hot and cold fluids make full thermal contact, maximizing heat transfer efficiency. Compact and efficient plate heat exchangers are particularly suitable for air-cooled chiller heat recovery due to their high thermal conductivity and small footprint.
2. Integrating Heat Pump Technology
Another effective approach is integrating heat pump technology into the system.Even though low-temperature air-cooled chillers operate at lower temperatures, their exhaust air or cooling loop still contains recoverable heat energy.
A heat pump can:
• Absorb low-grade heat from the chiller's exhaust
• Compress and elevate the temperature
• Deliver the upgraded heat to other applications
Using VRF (Variable Refrigerant Flow) heat pump systems allows flexible heat recovery according to real-time demand and adapts efficiently to varying operating conditions of the chiller.
3. Optimizing the Control System
A smart and precise control system is essential for effective heat recovery.The control system continuously monitors parameters such as:
• Temperature
• Pressure
• Flow rate
Based on real-time data, it adjusts the heat recovery equipment to ensure optimal performance.
When multiple heat-use terminals exist, the system must also intelligently distribute heat to meet different demands without wasting energy.
Conclusion
Through the combined use of high-efficiency heat exchangers, integrated heat pump technology, and intelligent control strategies, low-temperature air-cooled chillers can achieve substantial heat recovery. This not only enhances system energy efficiency but also contributes to greener and more economical operation.

How Can Ice Storage Chiller Systems Be Applied to a 1,000㎡ Cooling Project
2025-12-31
As global energy efficiency demands rise, many buildings are seeking more sustainable and cost-effective cooling solutions. Among these, the ice storage chiller system stands out for its ability to “shift peak loads,” offering both economic and environmental advantages. But how can it be effectively applied to a 1,000㎡ cooling area?
How Ice Storage Chillers Work
The operating principle of an ice storage system relies on the latent heat of ice. During nighttime, when electricity prices are lower, the system freezes water to store cooling energy. During daytime, when power demand and electricity rates peak, the ice melts to release cooling, meeting the building’s temperature requirements. This strategy not only reduces operational costs but also eases the load on the power grid during peak hours.Step 1: Calculating Cooling Load Accurately
The foundation of an efficient design lies in accurate cooling load calculation. For a 1,000㎡ building, the cooling load varies depending on its function:• Office buildings: approximately 100–120W/㎡
• Commercial spaces: approximately 150–200W/㎡
Taking an office example, a 1,000㎡ space requires about 100–120kW of cooling capacity. Factors such as building orientation, insulation, internal heat sources, and occupancy levels must also be considered to ensure precise system sizing.
Step 2: Selecting the Right Ice Storage System
Once the cooling load is known, choose an ice storage chiller with slightly higher capacity than the required cooling load (e.g., 100–120kW). The type of ice storage tank is also crucial:• Ice coil tanks melt quickly and are ideal for short, high-demand periods.
• Ice ball tanks offer compact size and higher storage density.
The choice depends on the site’s available space and daily cooling patterns.
Step 3: Developing Smart Operating Strategies
Two main strategies are typically used:• Full storage mode – All cooling is generated at night and stored for daytime use. Ideal for areas with high daytime electricity costs.
• Partial storage mode – Both the chiller and ice storage system work together during the day, offering more flexibility. Operators can adjust according to real-time electricity prices and cooling loads.
Step 4: Ensuring Proper Installation and Maintenance
Reliable performance also depends on professional installation and maintenance. Piping must be tightly connected, and electrical systems safely wired. Regular inspections should check pressure, temperature, and possible leaks in the storage tanks, as well as cleaning filters to maintain system efficiency.Smart Cooling for Medium-Sized Buildings
For a 1,000㎡ building, a well-designed ice storage chiller system combines smart control, load management, and efficient operation. It not only delivers stable indoor comfort but also reduces long-term energy costs, achieving both economic and environmental benefits.
Basic Construction of Reciprocating Injection Pumps
2025-12-31
The reciprocating injection pump is a positive displacement pump that relies on the reciprocating motion of a piston or plunger within the pump cylinder to achieve fluid delivery. Its fundamental structure primarily consists of three major components: the power transmission mechanism, the hydraulic end, and the auxiliary system.
1. Power End
The reciprocating injection pump is the core component that transmits power and achieves motion conversion. It primarily consists of a prime mover, a reducer, a crank-connecting rod mechanism, and a crosshead assembly. The prime mover is typically an electric motor or diesel engine, providing the initial driving force for pump operation. The gear reducer, tailored to actual operating conditions, decelerates the high-speed rotational output from the prime mover before transmitting it to the crank-connecting rod mechanism. This mechanism is the power-end critical component, converting rotational motion into reciprocating oscillation of the connecting rod. The crosshead assembly then transforms this oscillation into linear reciprocating motion of the crosshead slider within its guide rails. By connecting to the hydraulic-end piston, it drives the piston's reciprocating motion to complete the fluid suction and discharge process.
2. Hydraulic End
Reciprocating injection pumps directly contact the conveyed liquid and perform suction and discharge operations. They primarily consist of a pump cylinder, plunger/piston, suction valve, and discharge valve. The pump cylinder serves as the liquid conveyance channel, with its inner walls precision-machined to ensure smooth sealing during the reciprocating motion of the plunger/piston. The plunger/piston, constructed from high-strength, wear-resistant, and corrosion-resistant materials, performs periodic linear reciprocating motion within the pump cylinder driven by the crosshead assembly. Suction and discharge valves ensure unidirectional fluid flow, typically employing ball valve or disc valve configurations. The sealing performance between the valve seat and valve core directly impacts the pump's volumetric efficiency.
3. Auxiliary Systems
These systems are essential for ensuring the safe and stable operation of reciprocating injection pumps. They include lubrication, cooling, sealing, safety valves and relief valves, instrumentation monitoring, and other systems.
4. Type
Reciprocating injection pumps can be further categorized into electric reciprocating pumps and diesel engine reciprocating pumps. Whatever your requirements may be, Elephant Machinery can integrate them into the design to deliver a tailor-made reciprocating pump solution for you!
Reciprocating pumps are irreplaceable in high pressure applications?
2025-12-31
In high pressure applications, reciprocating pumps are irreplaceable. Their unique operating principle endows them with exceptional high-pressure output capability, enabling stable operation in high-pressure environments with high volumetric efficiency—a performance unmatched by other pump types.
1. Working Principle
Reciprocating pumps transport liquids by altering the volume of the pump chamber through the reciprocating motion of pistons or plungers. Through periodic volume changes and valve switching, these pumps convert mechanical energy into liquid pressure energy, generating high discharge pressures. The pressure output of reciprocating pumps depends on the structural strength and drive power of the pump, not its rotational speed. Even at low flow rates, they can achieve hundreds or even thousands of megapascals of high pressure. They are indispensable in high pressure liquid transportation applications such as petroleum exploration, chemical processing, and high pressure cleaning.
2. High Efficiency
The high efficiency of reciprocating pumps is a key advantage that makes them highly favored in high pressure applications. As the piston or plunger reciprocates within the pump cylinder, the volume change within the pump chamber is precisely controllable. Provided the seals are effective, the entire volume of liquid drawn in can be expelled, typically achieving volumetric efficiency exceeding 90%. In prolonged, continuous high-pressure operations—such as material transfer in chemical plants or water injection in oil and gas fields—they significantly reduce operating costs and enhance system energy utilization, making them indispensable to modern industry.
3. High Stability
High stability is the core guarantee for reciprocating pumps to operate continuously and reliably in high pressure applications. Their structural design ensures robust performance during operation. Core components such as the pump cylinder and piston/plunger are typically precision-machined from high-strength alloy materials, offering exceptional rigidity and fatigue resistance. This enables them to withstand periodic impact loads under high pressure conditions without deformation or damage.
4. Reliability
Reliability is the cornerstone of reciprocating pumps' trustworthiness in high-pressure applications, with their structural characteristics enabling long-term stable operation. First, they feature fewer components, with core moving parts employing mature mechanical designs that result in low failure rates and easy maintenance. Second, they demonstrate strong adaptability to conveyed media. With appropriate material and structural selection, reciprocating pumps reliably transport diverse fluids. In demanding environments like petroleum drilling and chemical processing—where reliability is paramount—their high dependability ensures continuous, safe production, establishing them as critical process equipment.
Reciprocating pumps are Elephant Machinery's flagship products, primarily categorized into piston pumps and plunger pumps. Our reciprocating pumps cover power ratings up to 1120 kW, deliver flow rates as high as 6000 LPM, and achieve pressures exceeding 280 MPa.
