Abstract

The invention relates to a hydraulic pressurizing oil tank. The hydraulic pressurizing oil tank comprises a tank body and a piston in the tank body and is characterized in that the tank body is provided with a first cavity and a second cavity, the piston is positioned in the second cavity and fixedly connected with a piston rod, the piston rod is positioned in the first cavity and provided with an inner cavity, and a spring is connected in the inner cavity and fixedly connected with the inner wall of the tank body. The hydraulic pressurizing oil tank is simple in structure and has the advantages of effectiveness in pressurizing, high operational reliability and long service life due to adoption of self-supply type pressurizing as compared with a traditional pressurizing oil tank.

Description

Technical field: [0001] The invention relates to the field of hydraulic equipment, in particular to an oil tank of a hydraulic system. Background technique: [0002] In the hydraulic system, the oil tank is mainly used to store oil, dissipate heat, and separate air and impurities in the hydraulic oil. The quality of the oil tank design directly affects the working reliability of the hydraulic components and the system, especially for the life of the hydraulic pump. For environments with high altitude or low air pressure, if a general open oil tank is used, it will often lead to a decrease in the inlet pressure of the hydraulic pump and cause cavitation of the hydraulic pump, which will seriously affect the normal operation of the hydraulic system. Therefore, a pressurized oil tank is required. , The pressurized oil tank can increase the pressure on the oil surface of the oil tank and prevent the hydraulic pump from cavitation, thereby effectively improving the high-altitude perf...
