Abstract

The invention relates to a system based on a super-gravity cyclone oil purifying device and an effect testing method thereof. The system comprises an oil tank, a hydraulic pump, a motor, an overflow valve, a throttling valve, a flowmeter, an inlet pressure gauge, an inlet sampling valve, the super-gravity cyclone oil purifying device, an oil outlet sampling valve, an outlet pressure gauge, a water outlet sampling valve, a moisture collector, an purified hydraulic oil collector, a slag outlet sampling valve, a solid particle collector and a particle detector. The effect testing method includes starting each sampling valve for sampling, and evaluating the oil purifying efficiency of the device by detecting the pollution state of the hydraulic oil at the oil inlet and the oil outlet of the super-gravity cyclone oil purifying device; further evaluating the moisture removing efficiency by collecting the hydraulic oil samples at a water outlet; analyzing and measuring the constituents and contents of separated solid particle pollutant by collecting the samples at the solid particle pollutant outlet. By the device, the solid particles and moisture in the hydraulic oil can be separated at the same time, and purifying effect can be evaluated.

Description

technical field [0001] The invention relates to a system based on a supergravity swirl oil purification device and its efficacy testing method. Based on a supergravity swirl oil purification device, according to the separation mechanism of the device for different phases of hydraulic oil, the invention proposes a hydraulic Oil purification systems and corresponding test methods. Background technique [0002] Hydraulic technology has the advantages of large output power, small size, light weight, compact structure, fast response, stepless speed regulation, and easy automation. It has become an irreplaceable part of my country's agriculture, industry, national defense and science and technology modernization. A very important basic technology. Studies have shown that at least 75% of the failures of the hydraulic system are caused by the pollution of the working medium. If the pollutants in the hydraulic system can be removed through reasonable and effective filtration, the ave...
