RED4 Electronic Governor for Electronic In-line Pump Tester

a. Governor Detection

First, open the governor cover, check inside if there is oil and other contaminants, clean it of oil and dirt, move 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 be smooth and sensitive.

b.Pump Detection

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

c.Pump Oil Detection

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