 QYZ-2 Model Automobile Air Brake System Test Bench

1.Function Introduction (double-chamber or three-chamber test)

   This test bench is used mainly for testing performance of air compressor, master valve, air chamber, quick release valve and four-circuit valve in brake system of high, medium and low models automobiles at home and abroad and carrying out double-chamber or three-chamber test of master valve. As test equipment of automobile maintenance, it is especially applicable for maintaining and testing city bus and other all vehicles using air brake. 

air compressor: The time required by air compressor to reach specified pressure value when air compressor runs at rated RPM. Master valve: the required time of inflating air from main tank into air chamber through master valve (the time through air);Air chamber: after air is inflated from main tank into air chamber to reach set pressure value, hold the pressure.Quick release valve: after air is inflated from main tank into sub-tank through quick release valve to reach set pressure value, hold the pressure. Four-circuit valve: the same with test of quick release valve.
