The Research And Design Of Fatigue Test Mechanism With High Pressure Gas Cylinder

The industrial’s development is concerned with the development of Cylinder’s industry. With the rapid development of science and technology, the application of high pressure cylinder is more and more widely, all kinds of production of high-performance cylinders are in continuous research, and many new high pressure gas cylinders are requested to be tested. This experiment device can achieve pressure cycle test of high pressure cylinders, regulate pressure in a larger range, control accurately and work stably. Water medium can meet the testing requirements of some composite cylinders. By fatigue test, we can improve the production technology of the cylinder, improve the comprehensive performance of the cylinder.According to the needs of high pressure cylinder’s fatigue test, the experiment device have to test volume40L, test pressure50L, and frequency10per minute. Through the comprehensive consideration, puts forward the technical route. From the start of testing process, ensure the scheme can satisfy the requirement of fatigue test. Through the theoretical calculation and manuals to complete the selection of hydraulic components, ensure them have good working performance and enough service life. Using the powerful function of Visual C++to develop test software, so we can easily control the test process and get the test results. From all aspects to complete the research and design of fatigue test mechanism with high pressure gas cylinder.Test device of hydraulic pressure system include plunger pump, motor, pump of medium, high pressure filter, pressure gauge, accumulator, cut-off valve, overflow valve, electro-hydraulic servo valve, one-way throttle valve, pressure regulating valve, pulse supercharger, oil filter, cooler, oil tank, water tank, etc. According to the technical route, we combine the hydraulic components into a whole through hydraulic pipe, and reasonably layout the location of the hydraulic components. Test device is divided into hydraulic control cabinet, comprehensive test cabinet, computer control cabinet.There are many advantages of it, such as simple structure, oil electric separation, easy operation and maintenance. The test device of high pressure gas cylinder can meet the requirements of gas cylinder manufacturers and inspection agencies.
