Problems solved by technology

Since the hydraulic tester tests the hydraulic system based on the working principle of single-branch one-by-one testing, and the hydraulic system has many branches and hydraulic components, it is quite difficult to detect, cannot be widely tested and applied, and is prone to secondary pollution

Abstract

The invention discloses a hydraulic state detection and maintenance vehicle. The hydraulic state detection and maintenance vehicle mainly comprises a van, a pollutant detection module, an oil tank, a variable constant-flow module, a first flow meter, a first sensor, a hydraulic control valve module, a temperature sensor, a pressure sensor, a detected hydraulic system B, a second flow meter, a second sensor, a variable constant-flow module, a data input-output module and a control module. According to the hydraulic state detection and maintenance vehicle disclosed by the invention, detection for the leakage amounts of each branch and each hydraulic component of the detected hydraulic system is realized; the output flow rate and the like of the variable constant-flow module are calibrated, and the requirements of the items of hydraulic system exhaust, hydraulic system installation and detection, hydraulic system maintenance, hydraulic system faults and the like on the flow rate and pressure are met; and the hydraulic state detection and maintenance vehicle is convenient to move, capable of moving as needed, simple and convenient to detect, capable of carrying out wide detection and application, and not liable to generate secondary pollution.

Description

technical field [0001] The invention relates to the technical field of hydraulic system application. Background technique [0002] Hydraulic technology is widely used in various fields of society with its unique advantages. The maintenance method of hydraulic system is to replace hydraulic oil and hydraulic components regularly. Now the common way of maintenance is after-the-fact maintenance, which not only causes abnormal shutdown, but also requires a lot of spare parts, thus causing great losses to users, and now countries are paying more and more attention to the process testing in use, and scientific maintenance is carried out according to the test results. At present, the existing domestic and foreign hydraulic testers suitable for process testing generally use pressure, flow and temperature sensors or connect the tester in series with the branch of the hydraulic system to measure the changes in parameters such as pressure, flow and temperature. . Since the hydraulic ...
