Problems solved by technology

[0002] The traditional hydraulic oil pump unit has large volume, high noise, external leakage, unfriendly man-machine, etc. Based on this, the design concept of the hydraulic motor pump came into being. The core idea is to integrate the driving motor and the hydraulic pump, eliminating the need Shaft unit, oil-cooled instead of fan-cooled motor, has the advantages of compact structure, low noise, good heat dissipation, man-machine friendliness, etc. There are mature series of motor pump products abroad, but the hydraulic pump is inherently insufficient in oil absorption, and it is quite serious and high-speed , the efficiency of the hydraulic pump is particularly low, so the efficiency of the hydraulic motor pump is not high, even lower than that of the traditional hydraulic oil pump set

Abstract

The invention discloses a hydraulic motor gear pump with impeller arranged on inlet for pressurizing liquid supply. The hydraulic motor gear pump is an integrated body of a motor, a centrifugal pump impeller and a gear pump; an oil inlet is provided with an impeller, and oil liquid reaches an oil suction port of the gear pump after being pressurized, so that the problem of insufficient oil absorption of the gear pump is well improved, especially at higher rotating speed, the oil absorption efficiency of the gear pump is improved more obviously, and meanwhile, cavitation noise generated due toinsufficient oil absorption is also avoided; and a motor rotor (10) is mounted on a main shaft (7) through an interference fit, a first bearing (8) and a second bearing (19) are supported on a housing(1), and a gear set (4) is mounted on a front end cover (3), is connected with the main shaft (7) through a first flat key (5), an impeller (16) is arranged between a rear end cover (15) and an innerend cover (14) and is connected with the main shaft (7) through a second flat key (17), and the two ends of the main shaft (7) are sealed through a first sealing member (9) and a second sealing member (20).

Description

technical field [0001] The invention relates to a hydraulic motor pump, in particular to an imported hydraulic motor gear pump with an impeller for pressurized liquid supply. Background technique [0002] The traditional hydraulic oil pump unit has large volume, high noise, external leakage, unfriendly man-machine, etc. Based on this, the design concept of the hydraulic motor pump came into being. The core idea is to integrate the driving motor and the hydraulic pump, eliminating the need Shaft unit, oil-cooled instead of fan-cooled motor, has the advantages of compact structure, low noise, good heat dissipation, man-machine friendliness, etc. There are mature series of motor pump products abroad, but the hydraulic pump is inherently insufficient in oil absorption, and it is quite serious and high-speed At this time, the efficiency of the hydraulic pump is particularly low, so the efficiency of the hydraulic motor pump is not high, even lower than that of the traditional hyd...
