2.Sagety precaution

Being operated, the nozzle tester must be far away from flame or high temperature place , such as welding and so on.

3.Purpose of the nozzle tester

It is used to adjust and calibrate the injecting pressure, atomizing quality, injecting angle and needle valve seas of nozzle of diesel ingine in order to ensure cxeelent power and economic performance of diesel engine.

4.Performance of the nozzle tester

Block the joint where the nozzle is connected. Pump oil to a pressure -over 30 MPa. Then stop pump and watch the pressure descending from 30 MPa. It is less than 2 MPa. within 3 minutes.

5.Operation and adjustment of the nozzle tester.

1. Fix the tester on stable work-table by using four holes of the base-plate.
2. Working environment must be clean, so must operator’s hands and clothes must be clean. No operating out of the room is allowed.
3. Precipitate light -10 diesel over hours. Filter it through strainer. Then put the filtered diesel into tank. Don’t put into it with unqualified diesel.
4. Testing of injection Pressure of injector assembly.

Turn the injector assembly tested onto the nozzle joint tightly with high

pressure pipe, then do the experiment and adjustment of pumping fuel. When pumping fuel,watch the reading on the pressure gauge.At the same time,compare it with the specified pressure range of the injector assembly to see if it is normal. If the presure is too high or too low,adjust the pressure spring of injector assembly. Experiment of

5. 5 Experiment of Atomizing Quality

Watch the atomizing quality of fuel injecting. The fuel grain should be tiny, well distributed. No fuel current (or drop) seen with eyes. No obvious fuel stain appears if it is injected on the oil absorbing paper. Color of fuel stain from center to outer circle should become lighter and form well distributed

circle.Pumping fuel action should be quick. There is no fuel drop or fuel dropping after pumping fuel. Atomizing should be correct. Its taper angle should be within specified range.

6.Maintenance of the nozzle tester.

1. Calibrating fuel must be good quality light diesel deposited over 48 hours.
2. When filling fuel, filter it with silk-cloth, Do not fill the tank with unfiltered diesel.
3. Cover the tester with anti-dust cover after testing.
