Background technology
At present, existing submersible pump is by the stator assembly and rotor assembly offer power in casing, impeller and blower inlet casing is utilized to be transferred out by liquid, blower inlet casing and the flow passage components constituting pump together with impeller, therefore water pump performance is had a great impact, be the part outside disleaf wheel, pump performance being had the greatest impact.But have again the difference of essence with impeller, impeller is revolving part, it is the part of liquid increase energy, is the decisive part of flow and lift, be also the part that pump efficiency is had the greatest impact simultaneously;And blower inlet casing is static, it liquid can not increase energy, and can only lose liquid energy, and namely the hydraulic structure design of blower inlet casing is the reduction reducing lift and efficiency by reducing energy loss.
Blower inlet casing adopts cast iron materials casting, and original blower inlet casing volume is relatively big, and not only production cost is high, and lower end import and inwall intersection exist corner angle, it is easy to cause foreign material wall built-up to cause blocking, the generation of turbulent flow can be caused to affect flow velocity;Subtended angle of blade is excessive simultaneously affects pump capacity and lift, causes that efficiency reduces.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of simple and compact for structure, processing technology is simple, can reduce turbulent flow generation, improve the Novel guide shell structure in service life.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of Novel guide shell structure, mesochite and a upper casing including several series connection, described mesochite upper end coordinates with impeller base, described mesochite and upper casing all include housing and cornerite is the flow deflector of β, described housing central section is provided with pump shaft via, described flow deflector is uniform to be arranged between pump shaft via and housing cavity, aperture, described housing lower end and inwall are round-corner transition, edge, described housing lower surface is laid with screwed hole, housing upper end cylindrical is provided with ring flange, and ring flange is laid with the unthreaded hole coordinated with screwed hole.
Preferably, described ring flange is provided with boss, described boss and housing lower end ostium, and on described mesochite, aperture is provided with the seam coordinated with impeller base, and described mesochite upper surface is provided with annular and alleviates groove.
Preferably, the height of described mesochite and upper casing is 121mm, external diameter is 164mm, aperture, housing lower end and inwall round-corner transition radius R=5mm, R '=11.5mm, cornerite β=70 ° of described flow deflector.
Preferably, described ring flange and housing exterior walls interval arrange reinforcement.
Adopt and have the beneficial effects that produced by technique scheme: utilize the aperture, housing lower end of mesochite adjacent between two or upper casing to coordinate with mesochite ring flange convex platform, impeller base is arranged in the seam of mesochite upper end, and body height is reduced to 121mm, shorten the distance between adjacent fan-wheel, add flow dynamic, reach energy-conservation, to improve pump head purpose;The generation of turbulent flow is reduced with inwall round-corner transition in aperture, housing lower end, improves flow velocity, and then improves pump efficiency;The annular utilizing mesochite upper surface alleviates groove to alleviate overall weight, saves raw material;The cornerite of blade is reduced to 70 ° and water velocity can be greatly improved simultaneously, improves pump head.This utility model adopts fluidic structures not only to save raw material, and annual raw material of saving is up to 20%, and improves pump head and efficiency.
