Abstract

The present invention discloses a testing system and testing method of a solenoid valve life. The testing system comprises a control end and a testing loop. The control end comprises a computer control terminal and a wireless network adapter. The computer terminal is responsible for equipment connection, testing mode control and data record and storage. The testing loop comprises a solenoid valve performance testing device, a pressure sensor, a gas tank, and a pressure reducing valve. The testing loop is responsible for the life cycle and performance testing of a solenoid valve to be tested. The testing method is that an automatic control mode with alternative life cycle and performance testing is used to test the solenoid valve to be tested. The testing system and the testing method have the advantages of automation, intelligence, integration, big data and high reliability, and the defects of high intensity, a long cycle, heavy workload, a low degree of intelligence, no testing of performance change and the like of existing solenoid valve life testing can be solved.

Description

technical field [0001] The invention relates to a testing system and method, in particular to an automatic solenoid valve life testing system and method, belonging to the technical field of electromechanical testing. Background technique [0002] As an important industrial control actuator, the performance of solenoid valve is directly related to the stability and safety of the entire system. Therefore, solenoid valve testing technology has become a very important industrial testing technology. Among them, the solenoid valve life test is mainly used to test the action life and performance changes of the solenoid valve, and evaluate its working reliability and durability. The test results can provide a theoretical basis for improving the reliability, safety and economy of the system. The design and manufacture of solenoid valve and the design of electromechanical system of fluid transmission are of great significance. [0003] Generally, the action life of solenoid valve can...
