The test bench is used to test the hydraulic pulse pressure fatigue resistance of brake tube, air conditioning tube, condenser, evaporator and other pressure vessels etc. During the test, the testing medium at the specified temperature circulates in the inner cavity of the test piece, and at the same time, the pulse pressure is applied to the inner cavity of the test piece for a certain number of cycles according to the specified frequency, pressure, and curve. the whole equipment have stable performance and is easy to operate and maintain. It has the functions of automatically performing pulse test, recording and saving data such as the number of impacts, temperature, frequency, etc. Faults can be preliminarily judged automatically. The test requirements and results are in line with the requirements of international standards.
