Description
Technical field
The present invention relates to axial piston pump, relate in particular to hydraulic engine plunger pump.
Background technique
Axial piston pump is a kind of high-pressure service pump type of oil hydraulic pump, has to seal reliable, volumetric efficiency advantages of higher, has therefore obtained to use widely.At present, plunger pump is as a Hydraulic power units independently, needing to connect to form motor-hydraulic pump unit by its overhanging pump shaft and independently motor or internal-combustion engine forms hydraulic power unit and carries out work, this connection needs devices such as shaft joint, pump bracket, because independently the motor volume is bigger, add annexes such as shaft joint, whole hydraulic power unit volume weight is just very big.The motor that is connected with plunger pump generally all contains the fan that cools off usefulness in addition, and therefore whole hydraulic power unit noise is also very big; Because plunger pump has outrigger shaft, therefore there is the approach of external leakage simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic engine plunger pump, directly drive the cylinder body that combines as a whole with rotor by motor windings, making electric energy be converted into hydraulic pressure can export.
The present invention is a kind of hydraulic engine plunger pump, cylinder body 12 is by clutch shaft bearing 2, second bearing 17 is supported on left pump cover 1, between the right pump cover (18), be provided with terminal box 6 on the pump case 5, motor stator 8 is installed in pump case 5, motor windings 7 is housed in the motor stator 8, there is rotor 20 motor stator 8 inside, be evenly equipped with rotor bar 10 in the rotor 20, respectively there is an end ring 9 its end face both sides, cylinder body 12 is installed in the endoporus of rotor 20, offer filler opening 18a on the right pump cover 18, offer oil outlet 1a in the pump cover 1 of a left side, be evenly equipped with a plurality of axial groove 5a on the internal surface of pump case 5, left pump cover 1, thrust plate 11 is arranged between the end face of cylinder body 12, uniform a plurality of plungers 13 in the cylinder body 12, plunger 13 is by piston shoes 15, backhaul dish 14, ball pivot 16, inclined-plane 18b on retracting spring 19 and the right pump cover 18 is adjacent to.
The present invention compares with background technique, the useful effect that has is: this hydraulic engine plunger pump two of drive motor, axial piston pump independently element become one from structure, not only make hydraulic power unit structurally greatly simplify, saved the connection transmission device, made that hydraulic power unit is compact more, volume is little, in light weight; And directly simplified power chain, electric energy is converted into hydraulic pressure through hydraulic engine plunger pump and can exports, and has higher efficient; Hydraulic engine plunger pump does not need outer projecting shaft, sealing reliably simultaneously, does not therefore have external leakage; The present invention has adopted but mode of oil cooling, has removed the fan in the motor, has therefore removed the air power noise source, and whole thus hydraulic engine plunger pump has excellent low-noise performance.The present invention have low noise, compact structure, efficient height, cooling convenient, do not have advantage such as external leakage, can be widely used in the hydraulic system as kinetic pump, also be highly suitable for the medium transport that mustn't leak outside simultaneously.
