Description
Technical field
The utility model belongs to pump equipment technical field, more particularly, to a kind of blower inlet casing for MODEL VERTICAL MULTISTAGE PUMP.
Background technology
Currently, the use of MODEL VERTICAL MULTISTAGE PUMP is more and more extensive, the cycle for being applied to cold and hot clear water in high-voltage operation system increases
Pressure, more parallel connection of pumps water supply of skyscraper, fire-fighting, boiler feedwater, the conveying etc. of cooling water system and various flushing liquors.
While using MODEL VERTICAL MULTISTAGE PUMP, commonly using the blower inlet casing coordinated with impeller is arrived, present blower inlet casing is led
Fluidity can be general, and the working efficiency of whole multistage pump is relatively low, and blower inlet casing used at present, and Corrosion Protection is poor, tough
Property it is poor, cause pump penalty, reliability is relatively low, energy consumption increase, the lost of life, maintenance cost increase severely.
Utility model content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of for MODEL VERTICAL MULTISTAGE PUMP
Blower inlet casing, it has the characteristics that good guide performance, Corrosion Protection, toughness, reliability, working efficiency and service life.
In order to achieve the above purpose, technical solution used by the utility model is：It is a kind of for MODEL VERTICAL MULTISTAGE PUMP
Blower inlet casing, including diversion shell, the diversion shell are carbon steel material, and the surface of the diversion shell uses electrophoretic process, institute
It states and is provided with upper shell and lower housing in diversion shell, water inlet, the upper casing are formed between the upper shell and lower housing
Body includes water conservancy diversion sector ribs and cover board, and the upper surface of the water conservancy diversion sector ribs is corresponding with cover board to be welded and fixed, the flow-guide fan
The lower surface of shape muscle is close to weld with upper shell, the central shaft etc. of distributing position and upper shell between the water conservancy diversion sector ribs
Away from the bending direction arrangement of the water conservancy diversion sector ribs is all clockwise.
Preferably, the diversion shell is provided centrally with pump core hole.
Preferably, the water conservancy diversion sector ribs are disposably stamping.
Preferably, the quantity of the water conservancy diversion sector ribs is 6.
With the above structure, compared to the prior art the utility model this have the advantage that：The utility model structure letter
It is single, by the way that water conservancy diversion sector ribs are arranged, on hydraulic structure so that diversion shell is compacter close, has flow conductivity well
It can so that the working efficiency of whole multistage pump is higher；Diversion shell uses carbon steel material, and uses electrophoretic process on its surface,
So that having excellent Corrosion Protection, toughness, reliability and service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 10, diversion shell；11, upper shell；12, lower housing；13, water inlet；14, water conservancy diversion sector ribs；15, cover board；
16, pump core hole.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work

Referring to Fig. 1, a kind of blower inlet casing for MODEL VERTICAL MULTISTAGE PUMP, including diversion shell 10, diversion shell 10 are carbon steel
The surface of material, diversion shell 10 uses electrophoretic process so that has excellent Corrosion Protection, toughness, reliability and use
Service life.
It is provided with upper shell 11 and lower housing 12 in diversion shell 10, is formed between upper shell 11 and lower housing 12 into water
Mouth 13, upper shell 11 include water conservancy diversion sector ribs 14 and cover board 15, the upper surface welding corresponding with cover board 15 of water conservancy diversion sector ribs 14
Fixed, the lower surface of water conservancy diversion sector ribs 14 is close to weld with upper shell 11, the distributing position between water conservancy diversion sector ribs 14 and upper casing
The central shaft of body 11 is equidistant, and the bending direction arrangement of water conservancy diversion sector ribs 14 is all clockwise, 14 disposable punching press of water conservancy diversion sector ribs
Forming is simple to manufacture conveniently.The quantity of water conservancy diversion sector ribs 14 is 6, and the effect which reaches is ideal.
Diversion shell 10 is provided centrally with pump core hole 16, and pump core hole 16 can be matched with pump core.
By the way that water conservancy diversion sector ribs 14 are arranged, on hydraulic structure so that diversion shell 10 is compacter close, has fine
Guide performance so that the working efficiency of whole multistage pump is higher.
The utility model is simple in structure, while there has been shown and described that the embodiments of the present invention, for this field
Those of ordinary skill for, it is possible to understand that do not depart from the principles of the present invention and spirit in the case of can be to these realities
It applies example and carries out a variety of change, modification, replacement and modification, the scope of the utility model is limited by the following claims and their equivalents
It is fixed.
