During operation, under the action of the cam and the plunger spring on the camshaft of the fuel injection pump, the plunger is forced to reciprocate up and down to complete the pumping task, and the pumping process can be divided into the following three stages.
Conclusion: Through the above discussion, the following conclusions are drawn
1 The total stroke L of the plunger reciprocating motion is constant and is determined by the lift of the cam.
2 The amount of oil supplied per cycle of the plunger depends on the oil supply stroke, and the oil supply stroke is variable regardless of the camshaft control.
3 The fuel supply start timing does not change with the change of the oil supply stroke.
4 Turn the plunger to change the end of the oil supply and change the oil supply.
It is intelligent control of the microprocessor, LCD display, communication with the computer, stable working pressure, small pulsation and convenient operation. It is widely used in biochemical, pharmaceutical, chemical, environmental protection and other industries to meet the requirements of continuous constant pressure and constant flow of liquids in the above industries.
