Equipment Description:
Computer Servo Hydraulic Bearing Fatigue Testing Machine HZ-1327 applies to all kinds of wire fatigue resistance test. Wire withstanding repeated stretching, compression and bending fatigue role in the fatigue performance of the merits of the product will affect the performance and life. Therefore, fatigue tests in many cases more directly reflect performance than steel strength test.
Dynamic fatigue testing machine in various types of fatigue testing machine, has a simple structure and easy maintenance of the hydraulic pressure source and no valve, the pump or cooling system, use operation, high efficiency, low energy consumption, so it is widely used in scientific research, aerospace, universities, and industrial production and other sectors.
Applicable industry:
It applies to steel manufacturers, quality inspection units, universities, etc.
