PQ-400 Double Spring Nozzle Tester

>>>>>>Parameter:

 Equipment with a manometric gauge for internal pressure regulation

 Digital display permits to calibrate the injector opening pressure

 One shot and continuous spraying test..

 rate of oil pressure and air pressure is 50:1

>>>>>>Opeartion:

Main Button:
A: Internal pressure meter
B: Air supply meter
C: Air supply throttle
If the throttle whirls in clockwise, quantity of air input will be less, and oil input is less as well. Inverse, the input oil will increase.
D: Governor valve
If the governor valve circumgyrate to the bottom, rate of oil pressure and air pressure is 100:1. For example, when air pressure 7kg, the oil pressure will be 700kg. 
E: Air switch valve
The air valve is opened by pulling, and closed by pushing.
