Abstract

The invention relates to a vacuum pump and an application system and method thereof. The vacuum oil well pump comprises a main pump body. A left pump body and a right pump body are connected to the two sides of the main pump body. A left end piston and a right end piston are respectively arranged at the left end and the right end of the middle piston; the middle piston is arranged in the main pump body, and the left end piston is arranged in an inner cavity of the left pump body and divides the inner cavity of the left pump body into a left end cavity and a left side cavity. The right end piston is arranged in an inner cavity of the right pump body and divides the inner cavity of the right pump body into a right end chamber and a right side chamber; the device is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The present invention relates to a vacuum pump and its application system and method. Background technique [0002] Seals are widely used in industrial production, and the service life and leakage are the main technical indicators to measure the sealing performance. As a widely used oil-pumping component in hydraulic systems, the vacuum oil pump's seal failure will reduce the sealing performance, resulting in internal leakage and external leakage of the oil cavity. Therefore, it is necessary to ensure the reliability of the sealing. The failure of the seal is affected by many factors, so it needs to be verified by conducting life and related performance tests. [0003] In the hydraulic system, the hydraulic pump is mainly used to pump oil, and the pumping method is very important to the system. The high viscosity of the oil can easily lead to the evacuation of the hydraulic pump, resulting in the failure of the hydraulic system to work properly and ...
