Problems solved by technology

[0004] The purpose of the present invention is to solve the existing problem in the prior art that the traditional electro-hydraulic servo valve is controlled by the controller, but after the controller is damaged, it needs to be dismantled as a whole and then taken out for maintenance. Pollution monitors are generally installed with bolts, and the installation of bolts is cumbersome and prone to wire slippage. The proposed electro-hydraulic servo valve pollution wear test device

Abstract

The invention belongs to the field of electro-hydraulic servo valves, and particularly relates to an electro-hydraulic servo valve pollution wear testing device. The device aims at solving the problems that an existing electro-hydraulic servo valve is controlled by a controller, a circuit and a connecting piece are easily damaged in the taking process of the controller, meanwhile, a pollution monitor is usually and fixedly installed by adopting a bolt, and the problems that the bolt installation is tedious, a cross thread is easily generated are avoided. According to the scheme, the electro-hydraulic servo valve pollution wear testing device comprises a device body, wherein a control box and the pollution monitor are arranged on one side of the device body. The structure of the electro-hydraulic servo valve pollution wear testing device is reasonable, a cover plate moves so as to drive a controller body to move and extend to the outside of the control box, the controller body can be taken out only by opening the cover plate, time and labor are saved, maintenance of workers is facilitated, when the device is taken out, the circuit and the connecting piece cannot be damaged, and meanwhile, a fixing block is moved so as to drive a L-shaped pressing rod to be separated from a through hole, a clamping rod extends into a clamping groove under the action of the elastic force of a first spring, so that the pollution monitor is convenient to fix and mount, and the use of the device is convenient.

Description

technical field [0001] The invention relates to the technical field of electro-hydraulic servo valves, in particular to an electro-hydraulic servo valve pollution wear test device. Background technique [0002] At present, the test devices designed for the pollution of hydraulic valves all adopt the test method of adding standard AC test dust or MTD test dust from the outside world. When the electro-hydraulic servo valve is actually used, the pollutants in the oil mainly come from the electro-hydraulic In the working system of the servo valve, the electro-hydraulic servo valve itself and other hydraulic components produce burrs, debris, etc. during operation, and the hydraulic system will produce a large amount of pollutants during the working process. [0003] The publication number is CN103307057B, which discloses an electro-hydraulic servo valve pollution wear test system, which consists of four parts: the first part is the power source of the test system, which provides ...
