vane pump with high pressure for injection molding machine

It is widely used in equipment with high requirements for flow stability and noise, such as precision cutting machinery, plastics machinery, leather processing equipment and so on.
Vane pumps with high pressure and low noise are based on the basic working principle of vane pumps. Inside the vane pump there is a set of free sliding vanes, which move along the groove between the rotor and the inner wall of the pump body. As the rotor rotates, the vanes are pushed out by centrifugal force, creating a number of relatively independent chambers. The volume of each studio changes with the rotation of the rotor, thus completing the cycle of oil suction and discharge.
Oil suction process: when the rotor rotates, the blades are pushed out by centrifugal force, the volume of the pump chamber increases, and the oil is sucked in.
Oil pressure process: as the rotor continues to rotate, the vane pushes the oil flow to the outlet. Due to the good seal between the vanes and the inner wall of the pump body, the oil is discharged under high pressure.
This process ensures the efficient operation of the pump, and because of the smooth movement of the vanes, the oil flow is not prone to large pulsations, thus realizing the effect of low noise and low pulsations.

vane pump Main features:

1. High pressure capability: the vane pump can withstand a maximum pressure of 21 MPa, suitable for hydraulic systems that require high pressure output. Its ability to withstand high pressure makes it excellent in hydraulic drive systems, especially in applications requiring high pressure output.
2. Low noise design: thanks to the precise manufacturing process and optimized vane structure, with high pressure and low noise vane pumps with low operating noise. This is very important for industrial applications that require a quiet environment, such as precision machinery, laboratory equipment.
3. Small pulsation: due to the working principle of the vane pump and precision manufacturing, the pump’s pulsation is very small, to ensure that the pressure fluctuations in the hydraulic system is small, the flow is more stable, which is conducive to the stable operation of precision equipment.
4. Reliability and stability: through precision manufacturing, the pump components are strictly processed and tested to ensure long-term operational reliability. Stable quality and performance enable it to maintain excellent performance even in complex environments.
5. Adapt to the requirements of high-precision and low-noise equipment: Due to its excellent low-noise and low-pulsation characteristics, this vane pump is suitable for use in equipment with high requirements for precision and noise to ensure smooth and efficient system operation.
6. Speed range: the minimum speed of 750 rpm, the maximum speed of 1800 rpm, to adapt to the needs of different working conditions. The lower minimum speed ensures stable output at low speeds, while the higher maximum speed meets high flow requirements.

Vane pumps with high pressure and low noise are widely used in the following fields due to their high pressure, low noise and low pulsation:

1. Cutting machinery: in precision machining equipment, especially CNC machine tools and automated production lines, vane pumps can provide smooth, reliable hydraulic power, reduce the impact of noise on the operating environment, and improve machining accuracy.
2. Plastic machinery: plastic molding equipment, especially injection molding machines, blow molding machines, etc., the hydraulic system is required to stable output of high-pressure hydraulic oil, and the noise level must be controlled within reasonable limits to ensure that the working environment of the plant.
3. Leather processing machinery: leather machine in the production process requires stable hydraulic drive system, at the same time on the noise and flow of the smoothness of the high requirements. Low noise and high pressure ability of the vane pump can meet this demand, to ensure the high efficiency of the leather processing process.
4. Other high-precision equipment: for the need for high-precision hydraulic system equipment, such as experimental benches, test equipment, precision machinery, etc., low noise and low pulsation characteristics make this pump an ideal choice.
5. Industrial vehicles and agricultural machinery: especially in agriculture and industrial vehicles in the hydraulic system, high pressure and low noise pumps provide a stable power source to ensure that the equipment under high pressure stable work.
