Description
Technical field
The utility model belongs to pump technology field, relates to a kind of well submersible pump, particularly a kind of pump case of well submersible pump.
Background technique
Well submersible pump is a kind of longilineal MODEL VERTICAL MULTISTAGE PUMP, is used for extracting deep phreatic water, and in rural area, factory, water utility, railway and oil field etc. are widely used.The Main Function of well submersible pump pump case collects the liquid flowed out from impeller, and be transported to next stage impeller eye, the speed of liquid can be converted to pressure energy, and the basic rotational speed eliminating liquid stream, the hydraulic loss in pump case accounts for 40% ~ 50% of hydraulic loss in pump to have data to show, therefore pump case is an important speed energy converting member, and the quality of pump casing design has material impact to pump performance.
A kind of well submersible pump guide vanes [application number: 201220277154.1] disclosed in Chinese patent literature, comprise on stator spoon of blade and be distributed with upper profile line and the lower whorl profile that two are circular curve, the circular curve of lower whorl profile is parallel with described upper profile line and at the downward-sloping several angle in the water inlet of stator.This stator is pump case, operationally, water in impeller enters stator by the water intake of the periphery wall of stator, and collect in the middle part of the radial phase stator of stator, and then change the flow direction, make current along submersible pump axial flow to next stage impeller, and flow power loss when current flow in this stator comparatively greatly, cause diving lift of pump to be affected.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of pump case of well submersible pump, and the technical problem that the utility model solves reduces the loss of stream power, improves diving lift of pump.
The purpose of this utility model realizes by following technical proposal:
A kind of pump case of well submersible pump, comprise shell, air guide sleeve and between shell and air guide sleeve the blade of some arcs, it is characterized in that, described shell has guide channel, guide channel one end is water outlet, the other end is water intake, the interior water intake without leave of described guide channel diminishes gradually to water outlet, one end of described air guide sleeve is positioned at guide channel, the other end of described air guide sleeve is positioned at the outside of water intake, outer one end without leave of described air guide sleeve increases gradually to the other end, the inner of described blade extends to the edge that guide channel is positioned at water outlet one end, the outer end of described blade is stretched out water intake and is extended to the edge of the air guide sleeve the other end.
In use, pump case rotates, water flows to pump case from the outer side surface of shell and below, outer end portion due to blade is positioned at the outside of shell, therefore the water flowing to pump case from the outer side surface of shell can import in pump case from adjacent blades between housing exterior, the water flowing to pump case from below imports in pump case between housing outward end, and this structure facilitates water and enters the flow that also can improve pump case in pump case, thus improves diving lift of pump; Enter that water in pump case is mild under the guiding function of guide channel, air guide sleeve and blade changes flow direction simultaneously, water is assembled and edge acquisition axial flow power to water outlet, thus decrease water (flow) direction in radial direction to stream power loss when axially changing, thus improve diving lift of pump.
In the pump case of above-mentioned well submersible pump, described shell comprises cylindric peripheral board portion and round table-like interior coaming plate portion, and described interior coaming plate portion forms above-mentioned guide channel, has some stiffening ribs between described peripheral board portion and interior coaming plate portion.The outer cover quality of this structure is comparatively light, pump case is rotated smooth and easy.
In the pump case of above-mentioned well submersible pump, described air guide sleeve is positioned at the below that coaming plate portion is positioned at the end face of water outlet one end, the inner side of described blade extends to the edge that interior coaming plate portion is positioned at water outlet one end, and the inner opposite side of described blade extends to the edge that air guide sleeve is positioned at guide channel one end.This structure makes the end slope of blade the inner, forms enlarging between the end face of some blade the inners, and namely current are when blade the inner is collected and is cylindric axial flow, above-mentioned inclined side along rotate the enlarging formed be beneficial to water quickly through.
In the pump case of above-mentioned well submersible pump, the middle part of described air guide sleeve has intercommunicating pore.Intercommunicating pore is connected with the pump shaft of submersible pump.
In the pump case of above-mentioned well submersible pump, the described end face of blade the inner and the end face of blade outer end are arc surface.Make water flow through along the both ends of the surface that it is arc surface during blade rotation, make stable the flowing through of water, and can flow to more stably or flow out between blade, improve current stream power.
In the pump case of above-mentioned well submersible pump, the outer side surface that described blade stretches out guide channel one section flushes with the outer circumferential face in peripheral board portion.This structure can avoid disturbance current at pump case when rotating, and flow is stablized, thus can flow between blade more stably, improves current stream power.
In the pump case of above-mentioned well submersible pump, the curvature of described blade becomes large gradually to the inner from outer end.The curvature of blade outer end is relatively little, and for guiding water to enter in guide channel, when water flow is inner to blade, the curvature due to blade the inner becomes large, and therefore flow velocity increases, and water is flowed out at the water outlet from guide channel rapidly, improves current stream power.
Compared with prior art, this well decreases water (flow) direction with the pump case of submersible pump by the structure of guide channel, air guide sleeve and blade and loses to stream power when axially changing in radial direction, has the advantage that improve diving lift of pump.
