Description
Technical field
This utility model relates to pump class technical field, particularly relates to a kind of axial plunger pump。
Background technology
Plunger displacement pump is an important device of hydraulic system。It relies on plunger to move back and forth in the pump housing, makes the volume of seal operation cavity volume change and realizes oil suction, force feed。Plunger displacement pump has the advantages such as rated pressure height, compact conformation, efficiency height and Flow-rate adjustment convenience, is widely used in the occasion that high pressure, big flow and flow need to regulate, in such as hydraulic press, engineering machinery and boats and ships。Plunger displacement pump is generally divided into single plunger pump, horizontal plunger pump, axial plunger pump and radial plunger pump。1, single plunger pump: single plunger pump structure composition mainly has eccentric, plunger, spring, the pump housing, two check valves。Sealed volume is formed between plunger and pump housing hole。Eccentric rotation is gone around, and plunger pumps once, moves downward oil suction, and move upward oil extraction。The fluid volume that pump every revolution is discharged is called discharge capacity, and discharge capacity is only and pump structure relating to parameters。2, horizontal plunger pump: horizontal plunger pump is to be installed side by side by several plungers, by connecting rod slider with 1 bent axle or is pushed directly on plunger by eccentric shaft and moves reciprocatingly, it is achieved inhale, the hydraulic pump of discharging liquid。They also all adopt valve type flow distribution apparatus, and are mostly dosing pump。Emulsion pump in coal mine hydraulic supporting system is typically all horizontal plunger pump。3, axial plunger pump: axial plunger pump is the plunger displacement pump that the vibration-direction of piston or plunger is parallel with pump housing central shaft。Axial plunger pump utilizes the plunger parallel with power transmission shaft to move back and forth what produced volume change was operated in plunger hole。Owing to plunger and plunger hole are all circular pieces, adding and can reach significantly high class fit man-hour, therefore volumetric efficiency is high。4, d-axis swash plate plunger pump: d-axis swash plate plunger pump is divided into forced feed type and self-priming oil type two kinds。Forced feed type hydraulic pump is mostly the fuel tank adopting and having air pressure, by the hydraulic oil container of gas-pressurized, after starting machine every time, it is necessary to after waiting hydraulic pressure stain case to reach use air pressure, could operate machinery。Just start machine during such as the air pressure deficiency of hydraulic oil container, causing with piston shoes in hydraulic pump can be pulled phenomenon, go out to cause the heel and toe wear of backhaul plate and pressing plate in the pump housing。5, radial plunger pump: radial plunger pump can be divided into Flat valve and the big class of axle flow two。There is the shortcomings such as fault rate height, efficiency is low in Flat valve radial plunger pump。6, hydraulic planger pump: hydraulic planger pump is by the hydraulic oil container of gas-pressurized, after starting machine every time, it is necessary to after waiting hydraulic oil container to reach use air pressure, machinery could be operated。
Plunger in current plunger displacement pump is in the process realizing oil suction oil extraction, and plunger is vulnerable to cavitation erosion, thus producing groove or groove on the front end face of plunger, reduces the service life of plunger。
