Abstract
The utility model discloses a kind of Hydraulic pump, comprises the pump housing, motor, it is characterized in that: motor driving pinion, and small gear engages with gearwheel; Gearwheel and main shaft are coaxially fixed; Main shaft is fixed by the rolling bearing of above the pump housing and below; Slant face disc is fixed on main shaft; The bottom surface of the pump housing is evenly fixedly installed and organizes plunger pump more; Arrange sliding cap above the piston of described plunger pump, the below of sliding cap arranges restoring spring; Described sliding cap abuts with the below of slant face disc; The oil inlet pipe of described plunger pump is communicated with the oil storage tank of below; The oil outlet tube of described plunger pump is communicated with total oil outlet tube; The utility model has the advantages that: owing to adopting slant face disc, when slant face disc rotates a circle, each plunger pump completes and once moves up and down, and the pressure of each plunger pump is pooled to total oil outlet tube, therefore, can set the quantity of plunger pump as required; The high pressure requirement of petroleum industry can be met.
Description
Technical field
The utility model relates to technical field of mechanical equipment, is a kind of Hydraulic pump specifically.
Background technique
Existing Hydraulic pump generally adopts and singly organizes plunger pump, and therefore, pressure is restricted, and can not meet the needs of the occasion of high pressure, as oil equipment etc.In addition, the power of motor of existing Hydraulic pump is comparatively large, and long-play, wastes more electric power.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of high pressure hydraulic pump that can be used for petroleum industry, and concrete technological scheme is as follows:
A kind of Hydraulic pump, comprise the pump housing, motor, it is characterized in that: motor driving pinion, small gear engages with gearwheel; Gearwheel and main shaft are coaxially fixed; Main shaft is fixed by the rolling bearing of above the pump housing and below; Slant face disc is fixed on main shaft; The bottom surface of the pump housing is evenly fixedly installed and organizes plunger pump more; Arrange sliding cap above the piston of described plunger pump, the below of sliding cap arranges restoring spring; Described sliding cap abuts with the below of slant face disc; The oil inlet pipe of described plunger pump is communicated with the oil storage tank of below; The oil outlet tube of described plunger pump is communicated with total oil outlet tube; Described total oil outlet tube arranges pressure-limit valve and pressure gauge.
The gear ratio of small gear and gearwheel is 1:3-5.
The roller bearing shop of slant face disc and described top arranges plane bearing, and slant face disc abuts with described plane bearing.
Between slant face disc and sliding cap, plane bearing is set.
Described sliding cap shaped is hemisphere.
The quantity of described plunger pump is 8 groups, is uniformly distributed.
The utility model has the advantages that: owing to adopting slant face disc, when slant face disc rotates a circle, each plunger pump completes and once moves up and down, and the pressure of each plunger pump is pooled to total oil outlet tube, therefore, can set the quantity of plunger pump as required; Owing to have employed gear graduation structure, the motor of same power can drive the slant face disc of larger diameter, and then drives more plunger pump, therefore, can meet the high pressure requirement of petroleum industry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the position view of slant face disc and plunger pump.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as Figure 1-Figure 2, the utility model comprises the pump housing 8, motor 1, motor 1 driving pinion 2, and small gear 2 engages with gearwheel 3; Gearwheel 3 and main shaft 21 are coaxially fixed; Main shaft 21 is fixed by top rolling bearing 5 and scrolls beneath bearing 16; Slant face disc 7 is fixed on main shaft 21; The bottom surface of the pump housing is evenly fixedly installed and organizes plunger pump more; Arrange sliding cap 9 above the piston 11 of described plunger pump, the below of sliding cap 9 arranges restoring spring 10; Described sliding cap 9 abuts with the below of slant face disc 7; The oil inlet pipe of described plunger pump is communicated with the oil storage tank 22 of below; The oil outlet tube of described plunger pump is communicated with total oil outlet tube 15; Transport pipe 13 on described total oil outlet tube 15 is arranged pressure-limit valve 12 and pressure gauge 14.
Small gear 2 is 1:3-5 with the gear ratio of gearwheel 3.
Slant face disc 7 and described top roller bearing shop arrange plane bearing 6, and slant face disc 7 abuts with described plane bearing 6.
Between slant face disc 7 and sliding cap, 9 arrange plane bearing.
Described sliding cap 9 shape is hemisphere.
The quantity of described plunger pump is 8 groups, is uniformly distributed.
The import of described plunger pump arranges spheroid 18, and described spheroid 18 only can move to plunges pump body direction; The outlet port of described plunger pump arranges the second spheroid 20, second spheroid and abuts with limit spring 19; Described second spheroid can only move to away from plunges pump body direction; High pressure oil is exported by transport pipe 13 by total oil outlet tube 15.The oil inlet hole place of plunger pump arranges filter screen 17.
Principle of the present utility model is: motor driving pinion, and small gear drives gearwheel to rotate, gearwheel and main shaft coaxial rotation, and then drives slant face disc to rotate, and the sliding cap of plunger pump presses down by the rotation of slant face disc successively, makes the outside pump oil of plunger pump.The oil outlet of each plunger pump is connected to total oil outlet tube by oil outlet tube, and therefore, the pressure of total oil outlet tube is the pressure summation of each plunger pump, and is regulated by pressure-limit valve and final go out oil pressure.
