Characteristics and Uses: This unit conforms to QC / T790-2007 "brake chamber performance requirements and test methods of" and HG 2950-1999 "automobile brake chamber rubber diaphragm" standards. It applies to all types of car brakes rubber diaphragm (film, cup) fatigue life test. You can multi-position while the parking chamber coating life test, driving test chamber diaphragm life, dual chamber composite coating life test load, high operating efficiency. PLC, touch screen control, the number of tests, work schedule, product model can be set adjustable recording, test frequency, automatically shut down the product after the completion of the number of tests, test data generated by the mini-printer to print. Flexible tooling design, suitable for all kinds of cars to install brake chamber assembly. Simulation of imported spring-load adjustable stop mechanism, with good interchangeability, fast clamping. The machine overall appearance, durable and practical. Technical parameters: 1. Air pressure: 0 ~ 1MPa 2. pipeline pressure: 0 ~ 1.2MPa 3. Pressure adjustment range: 0.15 ~ 0.85MPa 4.
