Electromagnetic valve service life testing system

Abstract

The invention discloses an electromagnetic valve service life testing system. The service life of an electromagnetic valve is tested by counting the effective switching times of the electromagnetic valve. The electromagnetic valve service life testing system comprises a voltage stabilizing circuit module, a connection voltage stabilizing circuit module, a display module, a voice alarming module, a key module, a central control module of an indicating lamp module, an electromagnetic valve driving module and a flow detection module. The electromagnetic valve service life testing system can test the service life of the electromagnetic valve in the state of simulating the whole process with water, intelligent interruption can be achieved, work data can be stored, the automation degree is high, and automatic processing can be achieved in the situations such as water outage, power outage, faults occurring due to the fact that the national standard is not met, and small water volume after the system is started; furthermore, the service life value of the action times of the electromagnetic valve can be set at will to meet the demands for testing the service life of electromagnetic valves of different types and with different purposes, and the service life value of the electromagnetic valve can be directly displayed through the display module and stored.

Description

technical field [0001] The invention relates to the field of life testing systems, in particular to a life testing system for solenoid valves. Background technique [0002] Solenoid valve is a kind of electromagnetically controlled industrial equipment. It is an automatic basic component used to control fluid. It belongs to actuator and adjusts the direction, flow, speed and other parameters of the medium in the industrial control system. Moreover, the control precision is high and the sensitivity is strong. [0003] The life of the solenoid valve is greatly affected by the use environment and working conditions. For example, it is used in higher temperature or corrosive fluid, or the control voltage is unstable, or the suction and discharge are too frequent, etc., which can affect its life. The national standard stipulates that Under normal circumstances (12bar constant pressure, the highest water temperature does not exceed 90 degrees), the number of solenoid valve action...

AI Technical Summary

Problems solved by technology

[0006] 1. When the solenoid valve is working with water, it has a certain pressure, which will affect the life of the solenoid valve. The above method ignores that the water will affect the life of the solenoid valve;

[0007] 2. The average time for each electromagnetic action is 6s, and the continuous operation of 150,000 times takes at least about 40 days. During this period, there are many uncertainties, such as power failure and damage to other systems outside the solenoid valve, which will affect the progress of the solenoid valve test. have to retest

[0008] 3. Working continuously for 40 days has very high requirements on the system, resulting in high cost of the test system

[0009] To sum up, the existing technical team’s solenoid valve life test is actually very unreliable, not only the conclusions drawn deviate greatly from the actual conclusions, but also the test cost is high
