The piston pump manufacturer describes the working stage of the plunger pump
Piston pump manufacturers tell us that the plunger pump is an important device in the hydraulic system. It relies on the plunger reciprocating movement in the cylinder block, so that the sealing chamber volume changes to achieve oil absorption, oil pressure. Let's take a look at the working phase of the plunger pump.
When working, under the action of CAM and plunger spring on the camshaft of the fuel pump, the plunger is forced to reciprocate up and down, thus completing the pumping task. The pumping process can be divided into the following three stages.
(1) plunger reciprocating motion total stroke L is constant, determined by the CAM lift.
(2) the fuel supply of each cycle of the plunger depends on the fuel supply stroke, the oil supply stroke is not controlled by the camshaft is variable.
(3) the oil supply time does not change with the oil supply journey.
(4) turn the plunger can change the end of oil supply, thus changing the amount of oil supply.
Through the plunger pump manufacturers, I believe we have understood the plunger pump work process.
