Abstract

A high-displacement ultrahigh-pressure radial plunger oil pump comprises a motor. An output shaft of the motor is connected with a rotor of the oil pump through a coupler, the oil pump is provided with a rectangular pump casing, the bottom surface of the rectangular pump casing serves as a mounting surface, at least two plunger cylinders are uniformly mounted on each of the top surface, the left surface and the right surface of the rectangular pump casing, an oil inlet end of each plunger cylinder is connected with an oil inlet check valve, an oil outlet end of each plunger cylinder is connected with an oil outlet check valve through a plunger, and the rotor and the plunger connected with the rotor form an eccentric cam mechanism. According to the technical scheme, plungers are fixed on three surfaces of the pump casing, and can be arranged by the aid of the mounting surface to the utmost extent on the premise of the simplest mechanical processing state. Moreover, a vane pump is used for supplying oil, all oil inlet valves are communicated together while all oil outlet valves are also communicated together, and thereby functions of the high-displacement ultrahigh-pressure oil pump are realized with cost as low as possible.

Description

Big displacement ultra-high pressure radial plunger oil pump
Technical field
The utility model relates to a kind of radial plunger oil pump.
Background technique
Of a great variety at hydraulic control system mesohigh oil pump, but the high pressure oil pump of big discharge capacity is very rare especially surpasses 63Mpa when pressure, and discharge capacity surpasses almost not having of 12mL.And float amount radial plunger pump structure 4~6 plungers that generally can distribute in a cross section, because discharge capacity is little, the power of drive motor is little, oil pump and motor can be direct-connected by the end face flange, so radial extension can be arranged more plunger.
But the vibrations of arranging the too big generation of ultrahigh pressure radial plunger pump power of motor greatly are too big, and motor and oil pump can not be direct-connected by the end face flange, all are to adopt base to install, and fix with foot screw and ground.Simultaneously existing 2 plungers that also only on the cross section, distribute.
Summary of the invention
The purpose of this utility model is exactly to increase oil pump capacity to improve oil pump life in as far as possible little mechanism, reduces the oil pump manufacture cost.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises motor, the output shaft of motor connects the rotor of oil pump by coupling, the pump case of described oil pump is a rectangle, the bottom surface of rectangle pump case is an attachment face, on its end face and left and right three faces at least two plunger cases are housed all, the oil inlet end of each plunger case connects in line check valve, and the oil outlet end of each plunger case connects fuel-displaced one-way valve by plunger; Described rotor and coupled plunger constitute eccentric cam mechanism.
Described oil pump is gear pump or vane pump.
Described pump case is a square, and six plunger cases of two rows are housed on the end face of pump case and left and right three faces.
Described pump case is a square, and nine plunger cases of three rows are housed on the end face of pump case and left and right three faces.
The in line check valve UNICOM of all plunger case correspondences is together by oil pump feed; The fuel-displaced one-way valve UNICOM of all plunger case correspondences together.
Adopt the utility model of technique scheme, in three equal non-movable piston of face of pump case, can be under the simplest state of machining, maximum using attachment face arrange plunger.And adopt the vane pump fuel feeding, all oiling valve UNICOMs together, all outlet valve UNICOMs have so just realized the function of big displacement ultra-high pressure oil pump together on alap cost.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises motor 9, and the output shaft of motor 9 connects the rotor 5 of oil pump 7 by coupling 8.In the utility model, the pump case 6 of oil pump 7 is a rectangle, but is preferred forms with the square, and oil pump 7 can be gear pump or vane pump, is preferred forms with the vane pump.The bottom surface of square pump case 6 is an attachment face, on its end face and left and right three faces at least two plunger cases 3 is housed all, and the oil inlet end of each plunger case 3 connects in line check valve 2, and the oil outlet end of each plunger case 3 connects fuel-displaced one-way valve 1 by plunger 4; Rotor 5 and coupled plunger 4 constitute eccentric cam mechanism.
Need to prove, six plunger cases 3 of two rows are housed altogether, and in line check valve 2 UNICOMs of all plunger case 3 correspondences are together by oil pump 7 fuel feeding on the end face of square pump case and left and right three faces; Fuel-displaced one-way valve 1 UNICOM of all plunger case 3 correspondences together.
Working principle of the present utility model is: oil pump 7 and motor 9 all are fixed on the support, and motor links to each other with the rotor 5 of oil pump by coupling 8; Motor 9 drives rotors 5 rotations, because rotor 5 be the eccentric cam structure, promotes plunger 4 to-and-fro motion, and low pressure oil is pumped by vane pump 7, enters plunger case 3 from line check valve 2, pumps from fuel-displaced one-way valve 1 after plunger 4 compresses superchargings and enters oil-way system.In line check valve 2 whole UNICOMs of six plunger cases of this system are together by the vane pump fuel feeding, and the also whole UNICOMs of fuel-displaced one-way valve 1 converge high pressure oil together and outwards provide super high pressure oil at a place.The overall discharge capacity of six plunger cases can reach 15~20ml.
In addition, nine plunger discharge capacities will be bigger if the utility model adopts three rows, and nine plunger cases 3 of three rows promptly are housed on the end face of square pump case and left and right three faces.
