Background

Plunger pumps are an important device of hydraulic systems. The plunger reciprocates in the cylinder body to change the volume of the sealed working cavity, so as to realize oil absorption and pressure oil. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, convenient flow regulation and the like. Plunger pumps are widely used in applications where high pressure, high flow and flow are to be regulated, such as hydraulic presses, engineering machinery and ships. Plunger pumps are divided into two representative structural types, namely axial plunger pumps and radial plunger pumps; the radial plunger pump belongs to a novel high-efficiency pump with higher technical content. The total reciprocating stroke L of the plunger pump plunger is unchanged and is determined by the lift of the cam. The amount of oil supplied per cycle of the plunger depends on the oil supply stroke, which is variable without control by the camshaft. The oil supply start timing does not change with the change in the oil supply stroke. The rotation of the plunger can change the oil supply end time, thereby changing the oil supply amount. When the plunger pump works, the plunger is forced to reciprocate up and down under the action of the cam on the cam shaft of the fuel injection pump and the plunger spring, so that the fuel pumping task is completed, and the fuel pumping process can be divided into the following two stages.
