Abstract
The utility model discloses a kind of drum type brake constant pressure frequency conversion pump, including the pump housing, the pump housing is made up of the inlet segment sequentially connected and compression section, water inlet is provided with the outside of the inlet segment, by some unit stator housings, sequentially stack combinations are formed for the compression section, impeller is provided with each unit stator housing, inner housing is enclosed with the outside of the compression section, shell body is provided with the outside of inner housing, gap is left between inner and outer shell and forms gas-liquid separation chamber, gas-liquid separation chamber connects in inner housing side with stage casing inner chamber, and gas-liquid separation chamber is provided with delivery port at the top of shell body.The drum type brake constant pressure frequency conversion pump of the utility model design, it adds a barrel shrond outside the pump housing, the liquid gas disengagement chamber of large space can be formed between barrel shrond and the pump housing, to realize that the bubble come out from the pump housing effectively ruptures, ensure efficiently separating for gas-liquid, can effectively lift the transfer efficiency of liquid and ensure the work lift of water pump.
Description
Technical field
Originally it is practical to be related to a kind of constant pressure frequency conversion pump, specially a kind of drum type brake constant pressure frequency conversion pump.
Technical background
Existing constant pressure frequency conversion pump is mostly sectional type structure, and its structure is as shown in figure 1, entirely the pump housing is mainly by inlet segment
1 ', stage casing 2 ' and water exit end 3 ' are formed, and the inlet segment 1 ' is provided with water inlet 11 ', and the stage casing 2 ' is by some unit stators
Sequentially stack combinations are formed housing 21 ', are provided with impeller in each unit stator housing 21 ', the water exit end 3 ' is provided with out
The mouth of a river 31 '.In use, using negative pressure caused by each impeller by liquid from inlet segment 1 ' suck, and after it is each through stage casing 2 '
The supercharging of impeller, afterwards water under high pressure directly by water exit end 3 ' delivery port 31 ' out.In the above process, when each impeller pair
Liquid can produce many bubbles during being compressed supercharging, but in above structure, the liquid after stage casing 2 ' is pressurized is direct
The delivery port 31 ' of water exit end 3 ' is introduced to, centre does not have buffer area, and this can cause caused bubble timely and effective not break
Split, cause liquids and gases not efficiently separate and be just admitted to conveyance conduit, its result will have a strong impact on the transfer efficiency of liquid
With the lift of water pump.
Utility model content
In view of the above-mentioned problems, the utility model devises a kind of drum type brake constant pressure frequency conversion pump, it is added outside the pump housing
One barrel shrond, the liquid gas disengagement chamber of large space can be formed between barrel shrond and the pump housing, to realize the gas come out from the pump housing
Bubble effectively rupture, ensures efficiently separating for gas-liquid, can effectively lift the transfer efficiency of liquid and ensure the work lift of water pump.
To achieve the above object, the utility model uses following technical scheme：
A kind of drum type brake constant pressure frequency conversion pump, including the pump housing, it is characterised in that：The pump housing by the inlet segment that sequentially connects and
Compression section is formed, and is provided with water inlet on the outside of the inlet segment, and the compression section is by some unit stator housings sequentially stack combinations
Form, impeller is provided with each unit stator housing, inner housing is enclosed with the outside of the compression section, is provided with the outside of inner housing outer
Housing, leaving gap and form gas-liquid separation chamber between inner and outer shell, gas-liquid separation chamber connects in inner housing side with stage casing inner chamber,
Gas-liquid separation chamber is provided with delivery port at the top of shell body.
The utility model forms the gas-liquid separation chamber of large space by the inner and outer shell structure set on the outside of compression section, can
The highly pressurised liquid come out for compression section provides effective buffering, so that bubble caused by compression effectively ruptures, realizes gas-liquid separation, keeps away
Exempt from bubble to enter in conveyance conduit with liquid, can the transfer efficiency of liquid and the work lift of water pump effectively in riser tubing.
Brief description of the drawings
Fig. 1, existing sectional type constant pressure frequency conversion pump structural representation；
Fig. 2, structural representation of the present utility model.
Embodiment
As shown in Fig. 2 a kind of drum type brake constant pressure frequency conversion pump, including the pump housing, the pump housing is by the He of inlet segment 1 that sequentially connects
The combination of compression section 2 is formed, and the outside of the inlet segment 1 is provided with water inlet 11, the compression section 2 by some unit stator housings 21 according to
Sequence stack combinations are formed, and impeller 22 is provided with each unit stator housing 21.
The outside of compression section 2 is enclosed with inner housing 3, and the outside of inner housing 3 is provided with shell body 4, stayed between inner and outer shell 3,4
There is gap and form gas-liquid separation chamber 5, gas-liquid separation chamber 5 connects in the side of inner housing 3 with the inner chamber of stage casing 2, and gas-liquid separation chamber 5 is outside
The top of housing 4 is provided with delivery port 41.
The gas-liquid separation chamber 5 of large space is formed between the inner and outer shell 3,4 of above structure setting, can be that compression section 2 comes out
The a large amount of bubbles of band highly pressurised liquid provide effectively buffering so that compression caused by bubble effectively ruptured in this chamber, realize gas
Liquid efficiently separates, and avoids a large amount of bubbles from being entered with liquid in conveyance conduit, can effectively in riser tubing liquid conveying effect
The work lift of rate and water pump.
It is described above, only it is better embodiment of the present utility model, not the utility model is made any formal
Limitation, it is every to any simple modification made for any of the above embodiments, equivalent variations or to be repaiied according to technical principle of the present utility model
Decorations, in the range of still falling within technical solutions of the utility model.
