Working principle and application of hydraulic oil pump

2020-05-14 14:13:56

The hydraulic oil pump is composed of four parts: pump body, rectangular oil tank, pressure handle and ultra-high pressure steel wire braided rubber tube. There are three types of joints: straight through type, self sealing type and quick joint.

characteristic

1. Small size, light weight, easy to use, high working pressure.

2. Single stage pump station: the structure is simple, and the larger working pressure can be obtained.

3. Double stage pump station: in case of low pressure, high and low pressure pumps supply oil at the same time, which can obtain a large output flow. In case of high pressure, the low-pressure pump will automatically return oil without load through the unloading overflow valve. Reduce power consumption.

4. Pressure maintaining function: when there is no leakage in the external oil circuit, stop the pump and maintain the pressure for 5 minutes, and the rated pressure drop shall not exceed 5MPa

working principle

The oil tank is connected with the atmosphere, with seal volume, which can change alternately, and oil distribution device. When repairing, you should pay attention to the causes of wear, especially to 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 and tools, it can meet the requirements of lifting, bending, straightening, extrusion, shearing, riveting, dismantling, pressing and other work.

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

3. As a pressure test pump station of various high-pressure hydraulic components, high-pressure vessels and high-pressure rubber pipes.
