The mechanical working principle of the plunger pump is divided into two parts, the oil inlet process and the oil return process. When it works, the cam and plunger spring on the camshaft of the fuel injection pump force the plunger to make Up and down reciprocating motion, thus completing the pump oil mission. Plunger pump mechanical working principle First, the process of oil into the cam When the convex part of the turn, under the action of the spring force, the plunger downward movement, the upper space of the plunger (called the pump chamber) to produce a vacuum, When the upper end surface of the plunger opens the oil inlet hole on the plunger sleeve, the diesel fuel filled in the upper body oil passage of the oil pump enters the oil pump chamber through the oil hole, the plunger moves to the bottom dead center and the oil enters the end. Second, the oil return process plunger up oil, when up to the plunger on the chute (stop for the edge) and the sleeve connected to the oil return hole, low pressure oil pump chamber and the plunger head in the middle Hole and radial hole and oblique groove communication, a sudden drop in pressure, the oil valve in the spring force quickly closed, stop the fuel supply. After the plunger has to go up, when the convex part of the cam turn, under the action of the spring, the plunger down again. At this point they started the next cycle. Piston pump to a plunger principle, a plunger pump has two one-way valve, and the opposite direction, the plunger movement to a negative pressure within the cylinder, then a one-way valve to open the liquid is inhaled In the cylinder, when the plunger moves in the other direction, the other one-way valve after the liquid is compressed is opened, and the liquid sucked into the cylinder is discharged. This work continues to form a continuous movement of oil, which is the mechanical working principle of the plunger pump.
