Problems solved by technology

[0002] After the tractor hydraulic system is assembled, there will be impurities in the hydraulic pipelines and hydraulic components; secondly, due to the harsh working environment in the field, after the tractor is working, it is inevitable that dust and debris will enter the hydraulic system of the tractor, and then As the working time of the hydraulic system increases, the oil will also be polluted accordingly
In the actual use of the tractor, the user only relies on the filter element in the system to control the pollution degree of the hydraulic system. Since the user does not clean and replace the filter element in time, the precision components of the hydraulic system, such as control valves and joints, are often blocked, resulting in The oil temperature rises, seriously affecting the service life of the tractor

Embodiment Construction

[0009] Attached below figure 1 , attached figure 2 The specific implementation of the tractor hydraulic system cleaning device will be further described. Such as figure 1 , when using the cleaning system 1 to clean the hydraulic components, first connect the oil inlet and outlet ports of the hydraulic components to the oil inlet and oil return circuits of the quick-change joint group 9 through the auxiliary oil pipe, and turn on the motor switch of the motor pump group 4 , start the cleaning system, at this time the hydraulic pump of the motor pump group 4 pumps the hydraulic oil in the cleaning oil tank 2 into the system through the oil suction filter 3, and the hydraulic oil passes through the overflow pipeline 19, the check valve 6, the check joint Flow valve 7, quick-change joint group 9, circulating crude oil filter 11, circulating essential oil device 12, flow meter 13, cooler 14, and oil return pipeline 18 flow back into the cleaning oil tank 2 to form a circulating ...
