The manufacturer of high pressure oil pump introduces the working process and principle of high voltage plunger pump

Working process and principle of high voltage plunger pump

When using high pressure plunger pump, the reducer is driven by drum gear coupling. Drive the crankshaft to rotate by means of a reducer. The power of the high-pressure plunger pump is supplied by the motor through the crank linkage mechanism. The rotary motion of the micro pump is converted into the reciprocating motion of crosshead and plunger. With the plunger moving back to dead point, the volume of pump chamber increases and the pressure decreases gradually. When the pressure in the pump chamber is lower than the inlet pressure, open the suction valve at the inlet end of the high-pressure pressure test pump to inhale the liquid. As the piston moves to the front dead point, the pressure in the pump chamber increases. At this time, the suction valve of the low-pressure fuel pump is closed, the discharge valve is opened, and the liquid is extruded out of the liquid cylinder, so as to achieve the purpose of suction and discharge.

The reciprocating direction of the piston or plunger of the high-pressure piston pump is parallel to the central axis of the cylinder. High pressure axial piston pump is a kind of pressure oil supply hydraulic pump, its working principle is that the plunger changes volume by parallel reciprocating movement with the transmission shaft. Most hydraulic pumps use pneumatic tanks. Straight shaft swashplate high pressure piston pump: self suction type, with pressure supply. The automatic oil suction pump has strong self-priming capacity, and does not need external force to supply oil.

In the process of high pressure plunger pump, the working pressure of the hydraulic high-pressure piston pump depends on the pressure after each start.

The hydraulic tank supplies oil. The hydraulic tank must wait for the working pressure to reach the operating pressure in order to operate the machine. The requirements for precision, finish and wear resistance are very high. The pumping mechanism of high voltage plunger pump consists of two sets of precision accessories: plunger is composed of plunger sleeve, oil outlet is composed of oil outlet valve seat; two cylinder plugs are not interchangeable between two cylinder plug sleeves. The nozzle, spray gun, two-dimensional rotary nozzle and grinding nozzle are the components of the nozzle of high-pressure piston pump. Its mobile mode is divided into handheld and hand push. This kind of cleaning equipment is mainly used for the maintenance of industrial and mining enterprises, the cleaning of parts, and the cleaning and maintenance of various motor vehicles, agricultural machinery and industrial machinery. In addition, it is widely used in the cleaning and disinfection of urban buildings, shopping malls, restaurants, gymnasiums, swimming pools and other places. The working medium conditions must meet the requirements of normal temperature and clean water.
