pin vane pumps with high pressure for hydraulic press

The design of high-pressure pin vane pumps effectively improves the working pressure, working stability and noise control performance of the pumps, making them excellent in a wide range of high-pressure, high-efficiency and low-noise hydraulic systems.

pin vane pumps working principle:

1. High-pressure pin vane pump through the pin connection vane, so that the vane in the pump body to maintain a uniform distribution of force. This structural design combines floating side plate and double-edged vane technology to ensure that the pump under high pressure flow stability, low noise and long service life.
2. Pinned vane structure: the vane is connected to the pump body through a pin to ensure that the vane can be uniformly stressed in the working process to avoid uneven wear. This design greatly improves the service life of the vane and the stability of the pump body.
3. Floating side plate design: floating side plate automatically adjusted according to the pressure inside the pump, optimizing the internal sealing of the pump, reducing the leakage of hydraulic oil and improving the efficiency of the pump.
4. Double-edged vane technology: double-edged vane design increases the fluid flow area and reduces pressure pulsation and noise in the hydraulic system, thus providing smoother hydraulic output and ensuring efficient and stable operation of the system.
5. Low noise stator curve: new low noise stator curve design, so that the pump in the high-pressure working condition can still maintain low noise output, to meet the strict requirements of the noise of the working environment.

pin vane pumps main features:

1. High working pressure: high pressure plunger pin vane pumps have high working pressure, can withstand high hydraulic pressure (usually above 250bar), suitable for industrial systems that require large hydraulic power and high pressure output.
2. Space-saving and lower installation costs: due to the advantages of high working pressure, the pump can reduce the size of hydraulic actuators, control valves and piping, thus making the hydraulic system more compact, lower installation costs, the overall system design and integration becomes more economical.
3. Low-noise operation: through the optimization of double-edged vane and low-noise stator curve design, the pump can significantly reduce the noise during operation, suitable for low-noise requirements of the working environment, to enhance the comfort of use.
4. High efficiency and energy saving: the pump is able to provide stable flow and high efficiency hydraulic power under high pressure environment, and at the same time reduce the energy loss, effectively improve the overall efficiency of the hydraulic system and reduce operating costs.
5. Long life and high reliability: due to the design of the plunger pin vane reduces the wear between the pump body and the vane, combined with the sealing performance of the floating side plate, ensures the service life and high reliability of the pump body, suitable for long time, high load continuous operation.

High-pressure pin vane pumps are widely used in applications requiring high-pressure hydraulic power with high noise requirements due to their high-pressure, low-noise and high-efficiency features.

Its main application areas include:

1. Blow molding machine: blow molding machine needs high pressure hydraulic power to drive the machinery to ensure that the plastic material can be accurately blow molding. High-pressure pin vane pumps provide an efficient and stable hydraulic source.
2. Injection molding machine: in the injection molding process, high-pressure hydraulic system needs to provide enough power to quickly complete the injection and compression process. High-pressure plunger vane pumps can ensure that the injection molding machine in the high-pressure stable work to ensure product quality.
3. Bending machine: high-pressure pin vane pump can provide stable hydraulic power for bending machine, in the metal processing process, to ensure that the bending machine can accurately perform bending operations.
4. Tablet press: In the tablet press, high pressure hydraulic system is used to press the material into different shapes. High-pressure ram-type vane pumps provide a strong power output to ensure that the pressing process runs smoothly and has a long equipment life.
5. Other machine tools and automation equipment: such as CNC machine tools, hydraulic presses, etc., need to be operated precisely under high pressure. High-pressure plunger vane pumps can provide the necessary stable and efficient hydraulic power to meet the needs of these high-end equipment.
