Description
Technical field
The present invention relates to a kind of positive displacement pumps, especially vane type multi-stage booster immersible pump.
Background technology
The currently known deep submersible pump generally used is all multistage centrifugal pump, and such as " 0J " type series well is used latent
Water pump, but its there are the shortcomings that it is also very apparent, the single-stage lift of centrifugal pump is not high, it is desirable to improve lift, it is necessary to increase series,
Therefore, centrifugal deep submersible pump must be multistage pump, but multistage pump reaches after certain series because being restricted just by pump shaft rigidity
It can not be further added by series, in addition, series is more, axial force is bigger, therefore constrains the raising of discharge pressure.
The vane pump of positive displacement has very high efficiency, and single-stage lift is high, and without axial force, but nobody is used as so far
Immersible pump, this with it there are following two defect is related, first, the two of the outer end face of blade and the inner surface of the pump housing and blade
Side and left and right two static side plates all generate high-speed friction, cause to generate heat, or even transported medium is made to generate vaporization；Two
It is the enclosure space surrounded by rotor outer circle, pump housing inner cavity and two blades, volume constantly generates change in operation process
Change, when volume from large to small when, be susceptible to tired liquid situation, due to liquid Incoercibility, extra liquid quilt from gap
It forces and squeezes out, to generate noise and vibration., so, traditional blades pump may be only available for the conveying good oil product of lubricity, and
It can not be suitable for conveying the poor water of lubricity, therefore, vane pump is commonly used for oil pump, is not used as water pump.
Invention content
It is an object of the invention to：For above-mentioned vane pump there are the shortcomings that, propose it is a kind of can be with multi-stage booster, blade
It will not abrasion, the vane type multi-stage booster immersible pump that not will produce tired liquid.
In order to achieve the above object, vane type multi-stage booster immersible pump of the present invention by the pump housing 1, built-in rotor 2 and turns
The blade 3 of the radial slot slide fit of son 2 and the pump shaft 4 being keyed with the rotor 2 form, and are characterized in that：The pump
1 inner cavity of body is equipped with multiple vane pump modular units 5 along axis, and the vane pump modular unit 5 is by pump chamber assembly 6 and rotor
7 two large divisions of assembly forms, and pump chamber by being divided into upper cut water 8, the lower cut water 9 of low-pressure area and higher-pressure region by the pump chamber assembly 6
And the front baffle 10 being fixedly mounted with the two is formed with rear bulkhead 11, the inside of the upper cut water 8 is formed with the circular arc coaxial with rotor 2
Face 15, the radius of the arc surface 15 is equal with radius of the blade 3 from the radial slot of rotor 2 when overhang maximum value,
The width of the upper cut water 8 corresponds to 60 ° of central angles in 2 axle center of rotor, and the inside of the lower cut water 9 is formed with rotor 2 with half
The arc surface 16 of diameter, the width of the lower cut water 9 correspond to 60 ° of central angles in 2 axle center of rotor, the front baffle 10 and rear bulkhead
11 are equipped with the arc triangle constant breadth cam frid 12 coaxial with rotor 2 towards the inside of rotor 2, the rotor assembly 7 by
Rotor 2, be packed in 2 both sides of the rotor and synchronous rotary two side plates 13 and multiple slide fits in 2 radial slot of rotor
Blade 3 formed, 3 inner end both sides of the blade are formed with coaxial shaft 14, and the shaft 14 of 3 inner end both sides of the blade is distinguished
The front baffle 10 is inserted in the slot of the arc triangle constant breadth cam frid 12 on rear bulkhead 11, the front baffle 10 is formed with
Channel A23 is formed with channel B24, the projecting shaft direct connection of the pump shaft 4 and submersible motor 18 on the rear bulkhead 11.
The two sides of the upper cut water 8 and lower cut water 9 in the technology of the present invention solution can be equipped with multiple small balls
17。
The technical scheme is that multiple vane pump modular units 5 are housed along axis in 1 inner cavity of the pump housing, it is described each
Vane pump modular unit 5 is made of pump chamber assembly 6 and 7 two large divisions of rotor assembly,
Wherein pump chamber assembly 6 is the stationary part in the pump housing 1, and the machinery that rotor assembly 7 is pump.
Movement of the blade in the radial slot of rotor 2 is the control by arc triangle constant breadth cam frid 12 in above structure
The maximum overhang arc surface that radius is R2 in by arc triangle constant breadth cam slot of system, blade controls, and blade is outer at this time
It is accurate clearance fit between end face and the arc surface 15 of upper cut water 8, does not generate friction between them；In addition, two side plates
13 are fixedly mounted with rotor 2 and are integrated and synchronous rotary, and rotor 2 is again with 3 synchronous rotary of movable vane piece, therefore, two side plates 13 and blade 3
Basic synchronization rotates, and only generates a small amount of relative displacement between the two sides and both side plate of blade 3, does not generate high-speed friction, therefore
This will not generate heat.
By 2 external cylindrical surface of rotor, upper cut water 8 arc surface 15 and two blades between the enclosure space that is surrounded of angle
In operation process, volume is will not be changed, the reason is that the arc surface 15 of upper cut water 8 and 2 external cylindrical surface of rotor are
Concentric circles, two interlobate angles are fixed, therefore when two blades rotate, and the size of closed volume is constant fixed number, no
Tired liquid phenomenon can occur.And this two arc surface is decentraction in traditional blades pump, so when two blades rotate, volume is wanted
Continuous variation occurs, when volume from large to small when, necessarily lead to tired liquid phenomenon.
It is formed with channel 23 in front baffle 10 in modular unit, channel 24 is formed on rear bulkhead 11, by this
Structure design can make the medium output after pressurizeing in previous stage unit pressurize again into next stage unit, so carry step by step
High pressure forms vane type multi-stage booster immersible pump.
The positive effect of the present invention is；
1. being equipped with multiple vane pump modular units along axis in 1 inner cavity of the pump housing, and made in the front baffle 10 of each unit
There is channel 23, channel 24 is formed on rear bulkhead 11, the medium input after such structure can make previous stage unit pressurize is next
Grade unit pressurizes again, can Multi-stage lifting pressure, form that a kind of flow is identical and pressure can have different grades of vane type
Multi-stage booster immersible pump makes product reach diversification, and to meet different demands of the user to pressure, such structure only needs more
The pump housing and pump shaft of different length are changed, other parts are all general, and the generalization degree of product is high, production week
Phase can be obviously shortened, and production cost can be substantially reduced.
2. the present invention is modularized design, pump housing diameter under the same conditions, as long as changing the width of blade pump module,
Different flows is can be obtained, namely obtains the Multiple Sinking Pump of different flow, expands the range of flow and pressure limit of pump.
3. the vane type multi-stage booster immersible pump of the present invention has the function of that two-way liquor charging, motor carry out liquor charging when rotating forward, electricity
When machine is reversed, filter screen can be cleaned, it is not necessary to shut down disassembly, cleaning.
4. the outer end face of blade 3 and two sides without rubbing, will not generate heat, will not make transported medium vapour in operation
Change.
5. pump is not generated in operation because of liquid phenomenon, both eliminated noise and vibration further improves efficiency, and
Operate steadily, service life it is long.
