Hydraulic oil storage device with function of removing impurities

Abstract

The invention relates to a hydraulic oil storage device with a function of removing impurities. The storage device comprises a box body, two connecting pipes and two one-way valves, wherein hydraulicoil is arranged in the box body, the box body is in a cylindrical shape, two mounting holes are formed in the top end of the box body, and the mounting holes correspond to the connecting pipes; the connecting pipes are inserted into the mounting holes, and the connecting pipes are sealed and fixedly connected with the inner walls of the mounting holes; the one-way valves correspond to the connecting pipes, and the one-way valves are installed on the connecting pipes; and a impurity removing mechanism and a defoaming mechanism are arranged in the box body, wherein the impurity removing mechanism comprises a first filter screen, a fixing pipe, a connecting box and an oil pumping assembly. According to the hydraulic oil storage device with the function of removing the impurities, the functionof removing the impurities in the hydraulic oil through the impurity removing mechanism can be achieved; and moreover, the function of removing bubbles in the hydraulic oil through the defoaming mechanism can also be achieved.

Description

technical field [0001] The invention relates to the field of hydraulic equipment, in particular to a hydraulic oil storage device with the function of removing impurities. Background technique [0002] Hydraulic equipment is the carrier of the hydraulic system. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. Hydraulic equipment is the combination of various parts. The transmission force of hydraulic equipment is large. It is easy to transfer and configure, and is widely used in industrial and civil industries. The function of hydraulic cylinders and hydraulic motors, the actuators of hydraulic systems, is to convert the pressure energy of the liquid into mechanical energy, and obtain the required linear reciprocating motion or rotary motion. Design actions, modify components at will to achieve the desired work. [0003] Most of the existing hydraulic oil is stored in the oil ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing hydraulic oil is stored in the oil tank. After the hydraulic oil is used for a long time, there will be impurities mixed into the hydraulic oil. The impurities will not only reduce the sealing performance of the hydraulic equipment, but also increase the wear of the parts and shorten the service life. Air will also be mixed into the oil, and the compressibility of air is much greater than that of oil, so the elastic modulus of the hydraulic oil mixed with air is greatly reduced, the movement of the hydraulic cylinder is no longer continuous and uniform, and the valves, cylinders, and motors are prone to cavitation damage, which will cause The system pressure is unstable, and the pipeline and equipment vibrate
