PQ-400 Double Spring Nozzle Tester

 

 

 

 

 

 

PQ400 Double Springs Injector tester

 

1)      PQ400 tester takes high pressure air as power source to drive fuel pump, which produce 450bar high-pressure fuel, and meet the pressure and fuel delivery when injector is injecting.

2)      PQ400 tester adopts ECU and operating-button to implement one-time injection and continuous injection.

3)      PQ400 tester adopts manual air pressure regulating valve to adjust fuel injecting pressure, and air pressure throttling valve to adjust injecting speed.

4)      PQ400 adopts prevent-mist-cover which is made by high strength transparent plastic, protect operator separated with high pressure spay area, and make operator to observe spray discharge pattern easily.

5)      PQ400 installs clamping arm which is convenient to fix injector.

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
