RED4 Electronic Governor for Electronic In-line Pump Tester

1、Electronically controlled pump inspection and maintena

a. Governor Detection

First open the governor cover, Check inside if there is oil and other contaminants, Cleansed of oil and dirt, moves up and down the linear motor slider, To see if there stuck.

Connection RED4 Governor and RED4 control box，Adjusted according to the instruction manual throttle size, viewing rack position changes, should smooth sensitive.

b.Pump Detection

The main testing plunger for wear, camshaft for wear and, if it should be replaced.

c.Pump oil detection

The high-pressure pump installed in the test bench, connected RED4 control box and pump, According to each pump fuel injection data to adjust the amount of fuel injection pump，Start test bench to watch fuel injection quantity，Adjustment method and ordinary mechanical pump same.
