RED3 Electronically Controlled Pump Tester

Product Description
                  With the development of electronic technology and the improvement of people's requirements for vehicle emission indicators, a new type of high-pressure diesel pump for diesel engines is entering the market more and more. This is the electronically controlled high-pressure oil pump for diesel engines. The difference is mainly the speed governing mechanism and the pre-stroke adjustment mechanism. Ordinary mechanical pumps use the principle of centrifugal force to achieve speed regulation, and the pre-stroke is realized by adjusting the gasket. The electronically controlled high-pressure oil pump adopts an electromagnet or a linear motor to realize the speed regulation. The size of the electric signal can change the fuel injection amount. The pre-stroke uses the control sleeve added on the plunger or the internal cavity pressure controlled by the solenoid valve. (VE pump) is also completely controlled by electrical signals. Here we only introduce the structure, principle and maintenance of the electronically controlled high-pressure in-line pump.

Product Features 
1.This product can be used to debug all in-line pumps equipped with RED4 electronic governor manufactured by Japan Jacksell.
2.The performance of the products is the same as that of the imported control box.
3.The debugging data is consistent and can completely replace imported products.
4.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.
5.The product is highly integrated and reliable, and is the ideal debugging instrument for the current RED4 electronic governor.


How to use
               Connect the tester and the electronically controlled pump with a randomly configured cable. Turn on the 220V power switch first, then turn on the Red4 Power switch. The screen displays POWER=ON. Rotate the ADJ left and right to adjust the PWM value and change the throttle size. Turn off the "Red4 Power" oil pump and turn off the power. Press the ADJ button down to select the preset 4 files: 5%, 16.25%, 72.5%, 95%. Press “Pull Down” to pull back the switch, the instrument output PWM is 5%, press “Limp home”, the instrument output PWM is 95%. Both functions should be turned off during normal operation.
