Abstract
The invention relates to a draining pump, the upper part of the impeller of the draining pump is provided with a shaft sleeve which is connected with a motor drive shaft, a big camber blade connected with the shaft sleeve and a small camber blade that is not connected with the shaft sleeve; the radian of the two kinds of blades is the same, a round disc which has the functions of the connecting and strengthening is arranged in the middle of the two kinds of camber blades, the diameter of the round disc is less than the outer edge of the blade; the big camber blade and the small camber blade are all vertical to the round discs. The large camber blade and the small camber blade all bend and extend outward from the disc with a direction contrary to the rotation direction of the electric motor. The big blade extends downward along the shaft sleeve and forms the small diversion blades which are vertically to each other, the bottom is at the water inlet of the pump body, the radian of the small diversion blades equals to that of the big camber blade, but the width is less than that of the big camber blade, the diversion blades are connected with the big camber blade through a transition curved surface and forms an integrated body. The invention adopts the integrated structure of the diversion blade and the big camber blade, which considerably improves the draining efficiency of the draining pump, eliminates the disturbance to the water flow from the boundary surface and reduces the noise.
Description
Technical field
The present invention relates to be installed in the draining pump of getting rid of condensed water on the aircondition.
Background technique
During air-conditioner operation,, after water gathers to a certain degree, can drop onto in the drip trap of heat exchanger below, therefore draining pump is installed in water receiving disc condensed water be got rid of outdoor because the cooling meeting of air generates a large amount of condensed waters on the surface of heat exchanger.This type of draining pump requires to have certain flow and lift, and since Environmental Conditions to the strict demand of air-conditioning system noise, to limit within the specific limits the operating noise of draining pump.
Chinese patent ZL95107436.9 once disclosed a kind of draining pump technological scheme, this draining pump is the pump body that discharge opening is set in upper side by in the underpart suction port being set, rotation being accommodated in the intrinsic solid of rotation of said pump and above-mentioned solid of rotation motor rotating is constituted freely, above-mentioned solid of rotation has axial region, tabular big footpath blade, tabular path blade, has the parts such as disk of hollow portion to constitute.The blade of above-mentioned draining pump solid of rotation adopts the prismatic blade structure, this structure no doubt is convenient to the Mould Machining manufacturing, but the problem that has the workmanship inefficiency, and because there are significantly boundary in the tabular path blade of impeller bottom and tabular big footpath blade, the disturbance that this boundary increases to current, thus bigger noise produced.
Chinese patent ZL01801754.1 has showed another kind of draining pump structure.Change the draining pump impeller and also adopt the prismatic blade form, and, change draining pump and be provided with the condensed water collector ring in the periphery of blade in order to reduce noise.The draining pump of this structure is owing to taked the impeller of prismatic blade form, and workmanship efficient is comparatively low, and the efficient that is arranged so that the outside draining of blade of the peripheral collector ring of blade reduces greatly.
Summary of the invention
Technical problem to be solved by this invention is to overcome the existing defective of prior art scheme, and a kind of novel draining pump is provided, and both can improve drainage efficiency, can avoid producing big noise again, is a kind of novel draining pump of optimal design.
The technical solution used in the present invention is:
A kind of draining pump comprises:
The upper and lower pump housing;
Be installed in the pump chamber impeller and
The motor of impeller rotation;
Described upper impeller has axle sleeve and the blade that connects motor drive shaft, and described blade comprises macrobending blade that links to each other with axle sleeve and the little curved vane that do not link to each other with axle sleeve.
In the present invention, the impeller of draining pump can also be done following further improvement:
One disk is arranged in perpendicular to the axle sleeve plane, and this disk is the center with the axle center of axle sleeve, and described macrobending blade and little curved vane all stand on the described disk.
Adopt disk and curved vane compound mode, reinforce and strengthened the anti-current-rush ability of curved vane, improved the bulk strength of impeller.
Described little curved vane are between two macrobending blades.Each macrobending blade and little curved vane are all with the rotation direction in contrast to the motor sense of rotation, by the outwardly-bent extension of disk disk body.Large and small curved vane quantity equates, radian is consistent, and all the axle center with axle sleeve is that the center is the isogonism symmetrical distribution.Macrobending blade inner edge is directly connected in axle sleeve, and outer rim is positioned at the outside of disk; Described little curved vane inner edge has a segment distance from axle sleeve, and outer rim also is in the outside of disk.
The present invention adopts curved vane, and than common radial prismatic blade, resistance is less when rotated to comply with the curved vane of rotation direction, and noise is less.
On described disc, the dead ahead of little curved vane is provided with the perforation that isogonism distributes, and vertically connects the disk disk body.The side effect that reduces drainage efficiency that horizontal disk brought has effectively been dissolved in these perforation that are the isogonism distribution, has improved flow and lift, and can also dissolve bubble, plays the effect that reduces noise.
The present invention extends to form the water conservancy diversion small leaf at the macrobending blade downwards voluntarily along axle sleeve, and the water conservancy diversion small leaf vertically crosses mutually, and the bottom is positioned at the lower pump body water intake.The water conservancy diversion small leaf is consistent with macrobending blade radian, and width is narrower than the macrobending blade, links to each other by the smooth transition curved surface between macrobending blade and the guide vane, forms one.The present invention adopts the structure of this guide vane and macrobending blade one, has improved the drainage efficiency of draining pump widely, has eliminated the disturbance of separating surface to current, has reduced noise.
The present invention has a water outlet on lower pump body, the center line of described water outlet departs from the center line certain distance of lower pump body water intake.This structure Design is at the curved vane of impeller and custom-designed, and the water outlet by the biasing lower pump body has enlarged the water outlet inner wall area, makes the draining pump drainage efficiency of the impeller that adopts curved vane obtain improving greatly.
