At present, most engineering machinery works through a hydraulic system, wherein the hydraulic system mainly comprises a hydraulic pump, a hydraulic valve, a hydraulic cylinder, a hydraulic motor, hydraulic oil and the like, and the hydraulic oil is stored in a hydraulic oil tank and has the functions of energy transmission, lubrication and the like as a working medium. The hydraulic oil pump sucks hydraulic oil from the hydraulic oil tank, the hydraulic oil is pressurized and then is conveyed to actuating elements such as a hydraulic oil cylinder through components such as a hydraulic pipeline and a hydraulic valve, and the hydraulic oil which does work returns to the hydraulic oil tank through an oil return pipeline to work and circulate repeatedly. Because the working environment is changed greatly like the difference in temperature, produce the comdenstion water, or concrete pump truck pump-sending oil cylinder department brings into the influence of working environment such as moisture, in addition there are impurity pollutants etc. to follow entering oil tank on the hydraulic oil circulation route, therefore the hydraulic oil tank not only has the function of storing hydraulic oil, still need to have the effect of separating moisture, bubble and the impurity in the hydraulic oil concurrently.
Water and impurities can be deposited at the bottom of the hydraulic oil tank under the action of self gravity and need to be treated in time to prevent the water and the impurities from entering the hydraulic system again to cause pollution. For example, the impact force when the hydraulic oil in the oil return pipeline returns to the hydraulic oil tank causes impurities deposited at the bottom of the hydraulic oil tank to be stirred up again, and the impurities are mixed into the hydraulic oil to pollute the hydraulic oil. The impurities invade the hydraulic system along with the circulation of the hydraulic oil, which may cause the abrasion and even the blocking of the hydraulic valve core of the hydraulic valve, or the abrasion of the sealing element and the piston rod inside the hydraulic oil cylinder, which causes the leakage of the hydraulic oil cylinder, affects the normal use of the engineering machinery with the hydraulic system, and even causes accidents. In addition, excessive water content can cause emulsification of hydraulic oil, which can reduce the lubricating performance, accelerate the wear of high stress parts, generate cavitation damage, generate acidic substances to corrode metals, and the like, and affect the working reliability.
