Description
Technical Field
The utility model relates to a high-pressure pump field especially relates to a high-pressure pump bent axle that high accuracy has lubrication action.
Background
A high-pressure pump is a pump capable of providing a large lift. The ultra-high pressure pump and the supercharger are 2 types of ultra-high pressure generating devices. The national standard defines a pump with pressure more than 100MPa as an ultra-high pressure pump. With the development of the technology, the pressure of the ultrahigh-pressure water jet is more than 200 MPa. The ultra-high pressure pump is characterized by high pressure control, relatively low cost and more application to pressure below 300 MPa; the supercharger has the characteristics of low-pressure control, relatively complex structure and more application to pressure of 200-420 MPa.
The motor drives the crankshaft to rotate through belt transmission, and drives the plunger 6 to do reciprocating motion in the plunger hole of the pump body 5 through the crankshaft connecting rod mechanism, so as to realize water suction and drainage. When the plunger rod 6 is in a water suction stroke, the volume of the plunger cavity is increased, the one-way valve 3 is closed, the one-way valve 4 is opened, and low-pressure water enters the pump body to finish the water suction process; when the plunger rod is in a water pressing stroke, the volume of the plunger cavity is reduced, the one-way valve 3 is opened, the one-way valve 4 is closed, and water is pressurized to enter the energy accumulator 2 and then enters the injection head 1 through the high-pressure pipe for operation. The action of the one-way valve plays a role in controlling the high-pressure water to flow in one direction, namely a flow distribution function. The phases of 3 crank journals of the crankshaft in the circumferential direction are different by 120 degrees, so that when the crankshaft rotates, 3 plungers alternately perform water suction and water discharge. The discharged water enters an energy accumulator which has the function of eliminating pressure pulsation, namely, the function of stabilizing pressure and stabilizing flow.
