Abstract

The invention discloses an electromagnetic valve response time testing method which comprises the steps of fixing a to-be-tested electromagnetic valve on a testing bench; fixing the electromagnetic valve through a high-speed camera; transmitting a working instruction to the electromagnetic valve so that a valve pin of the electromagnetic valve extends out; receiving the image of the electromagnetic valve in a process from receiving the working instruction to total extension of the valve pin through the high-speed camera; and processing and analyzing the image so as to obtain the response timeof the electromagnetic valve and the action time of the valve pin through the image. The electromagnetic valve response time testing method has advantages of realizing testing to the response time andthe action time of the electromagnetic valve, facilitating debugging of the electromagnetic valve in use, and improving debugging precision of the electromagnetic valve.

Description

technical field [0001] The invention relates to the technical field of solenoid valve testing, in particular to a method for testing the response time of a solenoid valve. Background technique [0002] The solenoid valve has a response time in the process of receiving the action command and completing the action. In some applications where the response of the solenoid valve is high, it is necessary to accurately estimate the response time of the solenoid valve to provide correction parameters for the control of the solenoid valve. There is no method for detecting the response time of the electric solenoid valve in the prior art. Therefore, it is necessary to study a method that can test the response time of the solenoid valve. Contents of the invention [0003] The purpose of the present invention is to provide a method for testing the response time of a solenoid valve, so as to realize accurate testing of the response time and action time of the solenoid valve. [0004...
