Product features:

This product can be used to debug all in-line pumps equipped with RED4 electronic governor manufactured by Japan Jacksell.

The performance of the products is the same as that of the imported control box. The debugging data is consistent and can completely replace imported products.

The product uses wide input switching power supply, high-speed ARM7 main control chip, imported original integrated circuit, can complete all debugging functions of RED4.

The product is highly integrated and reliable, and is the ideal debugging instrument for the current RED4 electronic governor.

Inspection and maintenance of electric control pump:

1, governor detection

The structure of RED3 is basically the same as that of RED4. First, open the governor cover to check whether there is dirt such as sludge inside. If it is, clean it and move the slider of the linear motor up and down to see if there is any jam.

Connect the RED4 governor to the RED4 control box, adjust the throttle size according to the instruction manual, and watch the rack position change should be smooth and sensitive.

2, pump body detection

It mainly detects whether the plunger is worn or not, whether the camshaft is worn or not, and if so, it should be replaced in time.

3, pump oil quantity detection

Connect the high pressure oil pump to the test bench, connect the RED4 control box and the oil pump, adjust the fuel injection amount of each pump according to the fuel injection value of each pump, start the test bench to watch the fuel injection amount, if there is any discrepancy, make adjustments, adjust the method and the ordinary mechanical pump. the same.
