Key Points

Based on the study of a new method which can calculate the dynamic performance parameters with the dynamic pressure data of the valve in the high-speed on/off process, a test system for the dynamic performance testing of pneumatic solenoid valves is developed in this paper. The dynamic performance of a pneumatic solenoid valve that obtained by test is a key index data for selection and application. To study the dynamic process, a mathematic model of the dynamic pressure in the valve’s control cavity is built up. As analyzing the relationship between the movement of the valve spool and the dynamic pressure during its high-speed on/off process, the method proposed a new criterion that can pick out the key points of the spool’s movement by the data of dynamic pressure which can be obtained by test easily. Then, the dynamic performance parameters of the valve can be determined with those key points. The structure of the test system that formed on this method is presented. Comparing the test results obtained from the new test system build in this paper with the results obtained from the valve spool displacement laser detection system, it is showed that every characteristic parameter is matched well. The comparing error of total opening time delay and total closing time delay are less than 3%. It is verified that the new method can test the dynamic performance of pneumatic high-speed on/off valve accurately.
