Problems solved by technology

[0007] In order to solve the problem that the hydraulic oil at the sampling point in the existing monitoring (detection) device is directly sucked and sampled from the oil tank, the particulate pollutants are not evenly distributed throughout the hydraulic oil, causing the pollutant monitoring (detection) instrument to The results of monitoring (testing) are not accurate enough and real. This disclosure provides a device and method for monitoring (testing) the degree of contamination of hydraulic oil particles sampled from the drain valve. By setting a circulation loop, one-way The hydraulic oil in the pipeline before the valve flows and is in a state of sufficient turbulence, so that the pollutants deposited at the bottom of the tank or near the drain valve are fully mixed and evenly mixed, and the representative tank can be obtained at the drain valve Even the particle pollution degree liquid sample of the entire hydraulic system is monitored (inspected) by the pollution degree monitoring (inspection) instrument to ensure that the pollution degree monitoring (inspection) result is accurate and true, and it is not easy to cause misjudgment

Abstract

The invention discloses a device and method for monitoring (detecting) the pollution degree of hydraulic oil particles sampled from a drain valve, and belongs to the technical field of hydraulic oil monitoring (detecting). The device comprises a circulating circuit and a monitoring (detecting) circuit, wherein the circulating circuit comprises a one-way valve and a hydraulic pump for providing power, one end of the one-way valve is connected with one end of a first filter, the other end of the one-way valve is connected with an oil suction port of the hydraulic pump, reverse installation needsto be avoided, and an oil outlet of the hydraulic pump is connected with an oil injection filter in an oil tank through a third pipefitting; and the monitoring (detecting) circuit comprises a pollution degree monitoring (detecting) instrument, and the pollution degree monitoring (detecting) instrument is connected in parallel on the circulating circuit. The circulating circuit is arranged, thus flowing of hydraulic oil in a pipeline before the one-way valve can be in a fully turbulent state, pollutants deposited at the bottom of the oil tank or the bottom of the oil tank near the drain valvecan be mixed evenly, and a particle pollution degree liquid sample representing the oil tank and even the whole hydraulic system can be obtained at the drain valve.

Description

technical field [0001] The invention belongs to the technical field of monitoring (detection) of hydraulic oil, and more specifically relates to a device for monitoring (detecting) the degree of pollution of hydraulic oil particles that is sampled from a discharge valve. Background technique [0002] In a hydraulic system, power is transmitted and controlled by means of hydraulic fluid in a closed circuit. Hydraulic fluid is both a lubricant and a power transmission medium. The presence of solid particulate contamination in hydraulic fluids not only hinders its lubricating properties, but can also cause wear and even failure of components. The solid particle pollution degree of hydraulic oil is closely related to the performance of the hydraulic system, such as reliability and durability, so the pollution degree should be controlled within the allowable range of the hydraulic system. But the premise is that the hydraulic fluid must be monitored (inspected) in real time or ...
