Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Such as figure 1 As shown, the hydraulic valve debugging method of this embodiment includes the following steps:

[0026] S1: Test the change of the magnetic field strength of the solenoid coil of the hydraulic valve and at least one working parameter among the pressure, flow and current parameters of the valve stem of the hydraulic valve, and transmit the test results to the controller;

[0027] S2: According to the change of the magnetic field strength of...

Abstract

The invention provides a hydraulic valve debugging method. The method comprises the following steps that S1, magnetic field intensity changes of an electromagnetic coil of a hydraulic valve and at least one working parameter of pressure, flow and current parameters of a valve rod of the hydraulic valve are tested, and test results are transmitted to a controller; S2, according to the magnetic field intensity changes of the electromagnetic coil of the hydraulic valve, the stroke direction of the valve rod is determined, and the parameters of the valve rod of the hydraulic valve are compared with preset thresholds; and S3, whether the working state of the valve rod is normal or not is determined, and when abnormality occurs, the debugging direction is determined. By means of the method, failure judgment can be accurately made in real time, corresponding debugging modes are started, and failures are solved.

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...
