Project Description

QYWN-01 hydraulic brake rubber cups for automobiles working durability test device

overview :

Hydraulic brake rubber cups for automobiles working durability test device,according to HG2865-1997 standard (Appendix B). Durability test device work by cabinet electric double layer heating constant temperature box, built-in type body structure, combine with hydraulic, electric,gas to test durability, control by computer and PLC to communication and routinization control,realize the real-time data acquisition, display, setting and control. Hydraulic control system is used to drive hydraulic solenoid valve to the main cylinder piston for reciprocating movement, the test specimen in a certain pressure, a certain frequency, a certain return trip, a certain temperature of the leather bowl, the amount of interference, determine whether the durability of the specimen is in line with the standard. The durability testing device of the work is in accordance with the “HG2865-1997” standard (Appendix B test method for the durability test of automotive hydraulic brake rubber.
