Description
Technical field
The present invention relates to a kind of vane type oil pump, particularly a kind of protected type peripheral pump for conveying electronic cooling agent.
Background technology
Peripheral pump is the active force to liquid by rotary blade, and liquid is transmitted dynamic with momentum on liquid motion direction
Can be to realize conveying liquid, nowadays the world and domestic each famous pump factory, grasp the producer of peripheral pump technology mainly with dynamic sealing
Based on structure, motor uses deep-groove ball rolling bearing.But existing peripheral pump technology there are problems that following not yet solving：1、
Noise is big：The main noise ratio produced by motor bearings, electric machine radiator is larger, and prior art is also difficult to reach some and uses
Application requirements are Jing Yin and close to Jing Yin state；2nd, special media difficulty of transportation：Existing peripheral pump is due to being dynamic sealing knot
Structure, because it is mechanical seal, can not convey special media substantially, can only convey the clear water under normal temperature, normal pressure；3rd, leakage problem：
Existing peripheral pump is due to being movable sealing structure, it is impossible to ensure complete No leakage, particularly dangerous medium, once let out
Leakage, consequence will be hardly imaginable；4th, pump housing volume is big：Existing peripheral pump needs servicing unit to radiate due to motor, causes structure
Therefore complexity, the overall volume of pump increases, and the requirement of so use occasion to requiring to limit space is just harsher；5th, motor
Bearing is easily damaged, and existing peripheral pump is due to without self balancing device, it is impossible to balancing axial thrust, and the deep-groove ball that motor is used is rolled
Bearing cannot for a long time bear axial force, have a strong impact on the service life of bearing, and then influence the service life of pump.
The content of the invention
The purpose of the present invention is to overcome deficiency of the prior art, there is provided a kind of noise is low, good airproof performance, small volume with
And long lifespan can convey the protected type peripheral pump of electronic cooling agent.
Above-mentioned purpose is realized, the present invention takes following technical scheme：The shielding of this conveying electronic cooling agent of the invention
Formula peripheral pump is mainly made up of impeller, the pump housing, pump shaft, stator rotor component etc., and pumped (conveying) medium electronic cooling agent is entered by suction inlet
Enter, rotated at a high speed through the impeller, most of liquid goes to system by the suction inlet, shielded through stator can and rotor
The outer rear bearing of gap flow direction of set and the gap of interior rear bearing, then flow to the leaf through the aperture in the middle of rear axle hook bolt through hole
Wheel, then the outlet of the suction inlet is flowed to, material is thus formed circulation loop；The pumped (conveying) medium of circulation has two aspect effects, one
It is to take away the heat that motor work is produced, two is the front and back bearings of lubrication motor.At the other suction inlet and forward flange sealing
Welded, formed the static seal between pump chamber and the forward flange, welded at rear bearing block and rear flange sealing, formed institute
The static seal between rear bearing block and the rear flange is stated, therefore whole electric pump No leakage can be accomplished.
Pump shaft of the present invention, using high intensity sliding bearing and thrust bearing and self-balance structure, makes pump rotor
Axial force itself reduces, and another high intensity sliding bearing and thrust bearing can bear axial force higher in itself, effectively
Solve the problems, such as that existing peripheral pump damages motor bearings due to axial force reason, substantially increase the service life of pump.
Compared with prior art, the present invention has following beneficial effect：1st, protected type peripheral pump of the invention is solved
The problem of high noise, is filled with pumped (conveying) medium in motor cavity, motor bearings is immersed in pumped (conveying) medium, such motor bearings with electricity
Arbor forms the basic transported medium absorption of noise that friction pair is produced, and greatly reduces noise, meets country and user to making an uproar
The requirement of sound this respect；2nd, protected type peripheral pump of the invention solves special media conveying and leakage problem, the knot of whole pump
Structure uses static seal structure, stationary seal structure, and dynamic sealing principle is formation medium mould, this layer of medium mould between rotating ring and stationary ring
It is sealing surface, but some special medias can not well form medium mould, like this, it is impossible to form complete sealing surface, hold
Easily leakage, therefore can not convey special media, and protected type peripheral pump of the invention uses static seal structure, and this sealing structure is welding
Face seals, it is not necessary to form medium mould to seal, therefore completely solves special media conveying and leakage problem.3rd, the present invention
Protected type peripheral pump due to the heat abstractor without auxiliary, the characteristics of with compact conformation, small volume, disclosure satisfy that some are led
The rigors of the peripheral pump small volume that domain needs.4th, protected type peripheral pump of the invention due to using high intensity sliding bearing and
Thrust bearing and self-balance structure, make pump rotor axial force reduction in itself, another high intensity sliding bearing and thrust bearing knot
Structure can bear axial force higher in itself, efficiently solve existing peripheral pump because axial force reason damages motor bearings
Problem, substantially increases the service life of pump.
Brief description of the drawings
Fig. 1 is a kind of protected type peripheral pump sectional drawing for conveying electronic cooling agent of the invention.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, peripheral pump is rotated by the high speed of the impeller 1 to make to form vacuum state in pump chamber 2, in atmospheric pressure
Or in the presence of system pressure, pumped (conveying) medium electronic cooling agent is pressed into the pump chamber 2, most of pumped (conveying) medium electronic cooling agent
The outlet 3 of pump is extruded by pumping chamber 4, liquid supercharging, ringing needed for equipment is played, sub-fraction is through in front-end bearing pedestal 5
Gap behind gap between aperture → stator can 6 and rotor shielding sleeve 7 → outer between bearing 8 and interior rear axle housing 9 → after
11 → pump housing outlet of spindle nose 14 → impeller inlet of bolt hole 3.Pump and motor connect together for overall, and machine, pump are coaxial, and motor turns
Son is intactly immersed in pumped (conveying) medium electronic cooling agent, and the iron core of rotor 12 is separated with pumped (conveying) medium by the thick thin plates of 0.5mm,
Stator core 13 is separated with the agent of pumped (conveying) medium electronic cooling by the thick thin plates of 0.5mm, and pumped (conveying) medium electronic cooling agent is through motor
The circulation in chamber 10 can take away the heat that the motor is produced due to work, substantially reduce the temperature rise of the motor, improve the electricity
The service life of machine, due to being full of pumped (conveying) medium electronic cooling agent in the motor cavity 10, therefore without movable sealing structure described
Pump chamber 2 separates with the motor cavity 10, greatly reduces the probability of leakage, and the pump housing is realized quiet close with forward flange 15 by welding
Envelope, rear bearing block 16 realizes static seal by welding with rear flange 17, and thus whole pump has accomplished complete No leakage.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvement can also be made, these improvement also should be regarded as of the invention
Protection domain.
