Abstract
The utility model discloses an axial piston pump comprising a transmission mechanism which drives the piston to do axial reciprocating movement and a hydraulic head; the transmission mechanism comprises a transmission axis and a swashplate device arranged on the transmission axis; an angel is formed between a normalizing line of the swashplate and an axial line of the transmission axis; the piston is parallel to the transmission axis; one end of the piston is connected with a return plate of the swashplate device. The axial piston pump solves the problems of big volume, vibration and noise of the existing radial piston pump; an axial piston pump with small volume, vibration and noise is provided.
Description
Technical field
The utility model relates to the emulsified liquid plunger pump.
Background technique
Plunger emulsion pump comprises the two large divisions, a part of driving mechanism, the connecting rod slider mechanism that comprise bent axle, links to each other with bent axle; A part is a fluid end, comprises the cylinder sleeve, the liquid suction valve that are arranged on the cylinder body, and an end of plunger stretches into cylinder sleeve, and the other end is connected with slide block in the driving mechanism; Admission chamber, go out sap cavity, form closed chamber between an end of plunger, valve body, the cylinder sleeve, closed chamber communicates with admission chamber by the liquid entering hole of liquid sucting valve, and the liquid outlet of liquid discharging valve with go out sap cavity and communicate.
Its working procedure: crankshaft rotating makes rotatablely moving of bent axle change the straight reciprocating motion of plunger into through connecting rod slider mechanism again.Plunger and cylinder sleeve, valve body etc. form closed chamber, and the straight reciprocating motion of plunger makes and working medium sucked the closed chamber volume-variation and discharges, thereby convert electric energy to the hydraulic pressure energy through suction, liquid discharging valve, the output highly pressurised liquid.This plunger pump is because the vibration-direction of plunger at bent axle in the radial direction, so also be referred to as radial plunger pump.
The radial plunger pump volume is big, and weight is big, moves inconveniently, and vibration during work, noise are bigger.
The model utility content
The problem that the utility model solves is existing radial plunger pump volume, vibration, noise is bigger provides a kind of volume, vibration, the less axial piston pump of noise.
This plunger emulsion pump, comprise and drive the reciprocating vertically driving mechanism of plunger, and by cylinder body, cylinder sleeve, liquid suction valve, admission chamber, go out the fluid end that sap cavity, emulsion box are formed, driving mechanism is to comprise transmission shaft, be arranged on the swash plate device on the transmission shaft, and swash plate normal and drive shaft axis have an angle; Plunger be parallel to transmission shaft, the one end is connected on the backhaul dish in the swash plate device.
The main distinction of the utility model and existing radial plunger pump is that the utility model drives the plunger to-and-fro motion with the swash plate device, and existing radial plunger pump is to drive the plunger to-and-fro motion with the crankshaft-and-connecting-rod slide-block mechanism.The swash plate device is a prior art, and it comprises swash plate, thrust-bearing, wobble-plate, backhaul dish, and swash plate is arranged on the transmission shaft, its normal with the transmission shaft several angle, thrust-bearing and wobble-plate, backhaul dish are housed on the swash plate.Under the drive of transmission shaft, swash plate promptly drives the backhaul dish and swings back and forth, and drives the to-and-fro motion of the plunger that is parallel to drive shaft axis with this.Identical as for its principle of fluid end with existing radial plunger pump.
As the further improvement to above-mentioned plunger emulsion pump, described plunger is a plurality of, is distributed on the circumference that drive shaft axis is the center.
In the swash plate device busy process, need lubricated.Lubricant oil in the course of the work, its temperature can raise.For to its cooling, the utility model has adopted following structure: described swash plate device is arranged in the housing of jacketed type, and this chuck communicates with going out sap cavity by the feed liquor pipeline, communicates with emulsion box by drain pipe.Go out the inner emulsified liquid that divides of sap cavity and enter in the chuck through the feed liquor pipeline, housing is cooled off, the lubricant oil that the sliding plate device is lubricated in the housing promptly obtains cooling.On being preferably in chuck and going out the liquid inlet pipe that sap cavity communicates flow control valve is set, enters emulsified liquid flow in the chuck with adjusting.
The beneficial effect of this plunger emulsion pump:
1, adopt inclined disc type transmission system, simple in structure, good manufacturability, easy to maintenance, rotate reliable.
2, adopt radial manner to arrange liquid suction valve group, compact structure.
3, adopt the water jacket water cooling mode rotary plate device to be cooled off economic and reliable.
4, adopt dipping bath formula mode that rotary plate device is lubricated, effectively reliable.
5, the associated mode that adopts transmission shaft and motor coaxle to arrange, reliable transmission; With elastic coupling flexible coupling and the transmission of swash plate device, noise is little, and vibration is slight, stable working.
6, adopt valve formula flow, improved the reliability of suction, draining, the volumetric efficiency height.
7, volume is little, and is in light weight, conveniently moving.Safety valve and pressure gauge are housed on the pump housing, easy and simple to handle, safe in utilization.

Fig. 2 is the left view of Fig. 1.
Embodiment
Axial plunger emulsion pump shown in Fig. 1,2 has swash plate 2 on the transmission shaft 1, its normal and driving axle center line have an angle, and thrust-bearing 3 and wobble-plate 4, backhaul dish 5 are housed on the swash plate.The ball seat that connects with the bulb of plunger 6 one ends is installed on the backhaul dish 5 that embeds in the spacer ferrule.The backhaul dish is equipped with radial ball bearing outward, and with round nut it is pressed on the swash plate with the backhaul dish.When transmission shaft rotated, swash plate 2 promptly drove backhaul dish 5 and swings back and forth, thereby drove plunger 6 reciprocating purpose that reaches suction water in the cylinder hole.
At the axial direction of transmission shaft, be uniform-distribution with five cylinder holes 8 that are arranged in the cylinder body 7 around transmission shaft, cylinder sleeve 9 and seal ring group wherein are housed.The radial direction of pump near pump head inhale, the draining end face, circumferentially five valve openings 10 that communicate with the cylinder hole, liquid suction valve group 11 and spring, seal ring, valve opening hold-down bolt etc. wherein are housed.Have the admission chamber 12 that communicates with the liquid entering hole of each liquid sucting valve group at the middle part of cylinder body, the liquid outlet of each liquid discharging valve group with go out sap cavity 13 and communicate.
In the cover 18, outside of inner cover was provided with overcoat 13, and chuck 14 is arranged between interior cover, the overcoat in swash plate device (comprising swash plate, thrust-bearing, wobble-plate, backhaul dish) was provided with, and interior cover, overcoat have been formed the jacketed type housing.Chuck 14 communicates with going out sap cavity 13 by liquid inlet pipe 15, communicates with emulsion box by the drain pipe that links to each other with liquid outlet 16 on the chuck.Chuck with go out the feed liquor pipeline that sap cavity communicates on flow control valve 17 is set.
