Abstract
The invention provides a kind of pump housing of Submersible Pump, belong to pump technical field.There is complicated, easy abrasion, the low technical problem of operating efficiency in the pump housing that it solves existing Submersible Pump.Being fixed with the pump housing of this Submersible Pump, including housing, housing on the inside of volute, volute has stator, and volute and stator are integral type structure.The present invention has the advantages that simple in construction, wear-resistant, operating efficiency is high.
Description
Technical field
The invention belongs to pump technical field, it is related to a kind of pump housing, particularly a kind of pump housing of Submersible Pump.
Background technology
At present, Submersible Pump is the larger product of demand in pump class product, to industrial and mining enterprises, high-floor feedwater, depth
Well water lift, agricultural irrigation, domestic water, change liquid conveying etc. play a positive role.General Submersible Pump mostly includes
The pump housing, the pump shaft being arranged in the pump housing, impeller and motor, pump shaft are connected by shaft joint with rotating shaft, the pump housing and associated electric motor.Pump
Body is typically made up of volute and stator, and current, and the volute and stator of the Submersible Pump pump housing are not integral structures, this
The pump body structure of sample is more complicated, is easily worn and torn by current, and serious even influences the operating efficiency of Submersible Pump.
The content of the invention
The purpose of the present invention is that there is provided a kind of simple in construction, operating efficiency is high the problem of having above-mentioned for prior art
Submersible Pump the pump housing.
The purpose of the present invention can be realized by following technical proposal：A kind of pump housing of Submersible Pump, including shell
Body, being fixed with housing on the inside of volute, the volute has stator, it is characterised in that described volute and stator is integrated
Formula structure.
Stator and volute design are integral type structure by the pump housing of this Submersible Pump, reduce the diffusance of stator, from
And reduce divergence loss.The gap of housing is controlled, so as to reduce disc friction.Reduce vane inlet angle, thus reduce into
Mouth hits loss.
In the pump housing of above-mentioned Submersible Pump, described volute include the seat of honour, lower seat, blade rack, upper lid and
Lower cover.Above-mentioned stator is connected by way of welding with the seat of honour and lower seat, then by way of spot welding with blade rack, upper lid
It is connected with lower cover.Stator is supported by blade rack, and blade rack can also play a supporting role to whole spiral case.
In the pump housing of above-mentioned Submersible Pump, described blade rack includes bezel ring, and support base ring on support,
Above-mentioned stator is connected with bezel ring, on support.
In the pump housing of above-mentioned Submersible Pump, described volute and stator are made of stainless steel material.
Compared with prior art, stator and volute design are integral type structure by the pump housing of this Submersible Pump, are reduced
The diffusance of stator, so as to reduce divergence loss, effectively raises the operating efficiency of Submersible Pump.
Brief description of the drawings
Fig. 1 is the structural representation of the pump housing of this Submersible Pump.
Fig. 2 is the structural representation of the stator of the pump housing of this Submersible Pump.
In figure, 1, housing；2nd, stator；3rd, the seat of honour；4th, lower seat；5th, blade rack；Bezel ring, on 5a, support；5b, support bottom
Ring；6th, upper lid；7th, lower cover.
Embodiment
The following is specific embodiment of the invention and with reference to accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
As depicted in figs. 1 and 2, the pump housing of this Submersible Pump, including housing 1, are fixed with volute, institute in housing 1
Stating has stator 2 on the inside of volute, described volute and stator 2 are integral type structure, and volute and stator 2 use stainless steel
Material is made.
Specifically, volute includes the seat of honour 3, lower seat 4, blade rack 5, upper lid 6 and lower cover 7, and above-mentioned stator 2 passes through
The mode of welding is connected with the seat of honour 3 and lower seat 4, then is connected by way of spot welding with blade rack 5, upper lid 6 and lower cover 7.Leaf
Plate rack 5 includes the ring 5a of lid 6 and support base ring 5b on support, and above-mentioned stator 2 is connected with the ring 5a of lid on support 6.Stator 2
Supported by blade rack 5, blade rack 5 can also play a supporting role to whole spiral case.
In other words, as shown in figure 1, stator 2 welds together with the seat of honour 3, lower seat 4, then with the ring 5a of lid on support 6, on
Lid 6 and lower cover 7 are spot-welded together, so constitute a volute, and such volute reduces the diffusance of stator 2, so carried
The high operating efficiency of electric pump.
Stator 2 and volute design are integral type structure by the pump housing of this Submersible Pump, reduce the diffusance of stator 2,
So as to reduce divergence loss.The gap of housing 1 is controlled, so as to reduce disc friction.Reduce the inlet angle of stator 2, so as to subtract
Small inlet hits loss, and then improves the operating efficiency of Submersible Pump.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although more having used 1, housing herein；2nd, stator；3rd, the seat of honour；4th, lower seat；5th, blade rack；On 5a, support
Bezel ring,；5b, support base ring；6th, upper lid；7th, the term such as lower cover, but it is not precluded from the possibility using other terms.Use these
Term is used for the purpose of more easily describing and explaining the essence of the present invention；It is construed as any additional limitation all
Disagreed with spirit of the present invention.
