Caterpillar hydraulic cylinder and valve pulse test bench, according to the requirement of the Caterpillar hydraulic cylinder and valve pulse test bench of practical experience and technology, combined with the actual situation, China, and special custom pulse test bench design in test bench has made some improvement.

        The test platform is a hydraulic and electrical testing system. It aims to complete the pulse fatigue test of the hydraulic cylinder and valve and the valve leakage test, and test the durability of the hydraulic cylinder and valve under the high pressure pulse. It provides powerful test data and performance guarantee for equipment production, especially new products.

        Pulse fatigue test is actually a destructive test. The durability of the test equipment under certain high voltage pulse (42MPa and below) is damaged by the final experimental items as the termination condition. Therefore, the requirements of the hardware and software of the pulse test rig itself are particularly high.

        DYNEX's main pump and reversing valve are especially suitable for test-bed projects because of their long life, stable operation and high commutation frequency. They have been widely applied in Caterpillar's test-bed and the test rig of many kinds of devices worldwide.

        Shanghai Marlin Electromechanical Technology Co. Ltd provides valve and hydraulic cylinder test platform has been the impulse test of millions of times, good performance.

 Cylinder and valve impulse test stand for Caterpillar R&D Center (China) Co., Ltd., are designed based on US Caterpillar's test stand experience and requirement, facing Chinese mainland real situation, the customized impulse test stands make some design progress on test stand then those in US.

  Test stands integrate hydraulic and electrical control.It dedicated to accomplish cylinder and valve impulse fatigue test and valve leakage test,testing the cylinder and valve long life under high pressure impulse.It supplies believable test data and performance guarantee for components, especially for newly developed products, before them leave factory are very important.

 Impulse fatigue test is a kind of test based on damage,which test a component's long-life(under 42Mpa or lower impulse pressure) till the product broken down.So a test stand itself's hardware and software must be strong enough and have good quality.

  Dynex main pump and direction valve for their long-life and stable working performance, high frequency reversing are very suitable for test stand project,which have been used many years in US Caterpillar test stand and widely used in many kinds of other test stand in the world.  

  Marlin Engineered Technologies(Shanghai) supplies cylinder and valve test stand have worked through tens of millions times of impulse test and still work well.
