           QYZ-2 model  Test Bench for testing air compressor, four circuit valve, quick release  valve

General introduction

This air braking system 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.

Advantages:

1.      It is with indicator lamp following each step and warn you the problems.

2.      It possesses high control sensitivity and strong controllability.

3.      It is easy to learn and operate.

4.      It can be matched with PLC computer to operate, display, save & print test results and curves.

Test items:

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.

Relay valve: test its on-off and air impermeability.

Differential valve:test its on-off and air impermeability.

Test the magnetic valve performance in air braking system.
