Abstract
The invention relates to an improved pump barrel of a centrifugal drainage pump, which comprises a centrifugal drainage pump parts, wherein, the water inlet of the pump barrel is connected with the water inlet pipe, and the inner wall end face of the pump barrel shows a size down cone toward the direction of the water feeding, which makes the pump keep steady drainage working state through improving the end face structure of the inner wall of the pump barrel, to avoid the continuous abnormal rumble noise after the air is sucked at the drainage subsequent steps produced by the pump made by the tradition craft.
Description
Technical field
The present invention relates to centrifugal draining pump parts, refer in particular to the pump case of centrifugal drain pump.
Background technique
Existing centrifugal drain pump technology, the end face of its pump case comprises that water intake is generally the plane and connects the pulsator intracoelomic cavity, during use, work as water inlet, the water outlet position all is higher than pump or independent water outlet position is higher than pump, when the liquid discharge will finish or wait for slow end or fix time end, that is to say, the water that needs to discharge finishes, but when pump does not also quit work, the water intake of pump can suck air or suck air on a small quantity, liquid in the discharge tube produces continuous backflow and discharges phenomenon again because of air enters the back, air can accumulate in the pump housing and can't discharge, at this moment just produced the continuous backflow and discharge noise of " banging-bang ", along with improving constantly of technical field industry standard, the higher draining pump that makes of this abnormal sound or noise can't satisfy technical requirements.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of improved centrifugal drain pump casing is provided, by the end face of pump case inwall is changed into conical end face by the plane, can keep normal working state after making pump when work, suck air, do not produce the continuous backflow of " banging-bang ", the noise of discharging again, specifically be achieved like this: improved centrifugal drain pump casing, pump case water intake and intake pipe join, and it is characterized in that the inwall end face of pump case is by big and little taper shape towards the water inlet direction.The pump case end-face structure of this oblique plane type has suitably increased inner chamber liquid storage amount, and air can be discharged from water intake along the inclined-plane after sucking, and the water of discharging in the water pipe is no longer refluxed, and it is very obvious to reduce noise.
In order to guarantee the timely smooth and easy discharge of air, have groove on the conical end face of pump case inwall of the present invention, described groove is communicated with water intake and pump case round cavity.Groove can help conical surface that inhaled air is discharged rapidly, avoids the bump of air and water in the pump housing, and water just can not cut off by air on impeller face, continues to keep centrifugal discharge, and the water in the discharge tube no longer produces backflow.Be arranged on that groove on the pump case inwall conical end face normally evenly lays.
The conical end face of pump case inwall of the present invention can be to be linking body structure with the pulsator cavity shell, also can be designed to combination according to different use occasions and piece together the knot form, the conical end face and the pulsator cavity shell that are the pump case inwall are the branch body structure, divide body structure to help the back of end face is designed to other shape, for example the multiple filtrating equipment of design band odontoid or a plurality of hole shapes etc. enters rubbish or foreign matter in the pump housing in order to filtration.For sealing air with stop entering of foreign matter, in the slit that the conical end face and the pulsator cavity shell of split splices, be embedded with soft Sealing.Certainly, the conical end face of pump case inwall also can be designed as integrative-structure or split composite structure, is embedded with soft Sealing in the splicing slit of described split composite structure.
The present invention is by improving the end-face structure of pump case inwall, and on the conical end face of inwall, groove is set, make the drainage works state of pump energy held stationary behind the suction air, the continuous abnormal sound of " bang creakily-bang and creak " appears in the pump that no longer produces the tratitional technology making after the draining follow-up phase sucks air.

Embodiment
Annotate: among the embodiment 1 or 2, the conical end face of pump case water intake inwall can be an integral structure, also can be the split composite structure by some splicings, if conical end face is the split composite structure, then is embedded with soft Sealing in the slit of each splicing.
