Abstract

The present invention proposes a hydraulic valve debugging method, including the following steps: S1: Test the change of the magnetic field strength of the hydraulic valve electromagnetic coil and at least one working parameter among the pressure, flow and current parameters of the valve stem of the hydraulic valve, and report the test results Transmission to the controller; S2: According to the change of the magnetic field strength of the hydraulic valve solenoid coil, determine the travel direction of the valve stem and compare the parameters of the valve stem of the hydraulic valve with the preset threshold value; S3: Determine whether the valve stem is in normal working condition, and When an abnormality occurs, the debugging direction is determined, and the present invention can accurately and real-time perform fault judgment, and enter a corresponding debugging mode to solve the fault.

Description

technical field

[0001] The invention belongs to the technical field of engineering machinery, in particular to a hydraulic valve debugging method. Background technique

[0002] At present, the slide valve mechanism is the most widely used structural form in various hydraulic valves. The slide valve is composed of three main parts: the valve body, the valve core and the valve cavity. By changing the position of the valve core in the valve body cavity, the slide valve The valve can realize the change and on-off of fluid flow. Spool valve jamming or even jamming fault is one of the most common faults and failure forms in the hydraulic system, which can generally be divided into two categories: hydraulic jamming, jamming and mechanical jamming. In layman's terms, jamming refers to the intermediate state between normal working conditions and jamming. Jamming means that the valve core cannot move. Jamming means that the valve core is difficult to move, which is not as smooth as n...
