1. Light weight, easy to use and high working pressure.

2. Single-stage pumping station: It has simple structure and can obtain large working pressure.

3. Dual-stage pumping station: When low pressure is applied, high and low pressure pumps can supply oil at the same time to obtain larger output flow. Under high pressure, the low pressure pump automatically returns oil without load through unloading relief valve. Reduce power consumption.

4. Pressure-keeping function: In the case of no leakage in the external oil pipeline, stop pump and keep pressure for 5 minutes, and the rated pressure drop does not exceed 5 Mpa.

Working principle

The oil tank is connected with the atmosphere, has sealed volume, the sealed volume can alternately change, there are oil distribution devices. When repairing, you should pay attention to the causes of wear, especially check the shaft bearing. After repairing, you should pay attention to prevent the leakage of the gear end face.

purpose

1. Equipped with oil cylinders or special machines, it can meet the working requirements of lifting, bending, straightening, extrusion, shearing, riveting, disassembly and pressing.

2. The device is used as a hydraulic power source in some mechanical equipment.

3. Pressure test pumping station for various high pressure hydraulic components, high pressure vessels and high pressure rubber hoses.
