Abstract

The invention discloses an impeller for an air conditioning draining pump and belongs to parts of the draining pump. The conventional air conditioning draining pump has the defects that draining flow and pumping head are limited by the impeller, and the draining efficiency is low. The impeller comprises a revolving shaft, and a plurality of main vanes and secondary vanes; in the impeller, the revolving shaft is used as the axle center; the main vanes are radially arranged on the revolving shaft from the axle center of the impeller; the secondary vanes are arranged at the bottom of the revolving shaft, and are correspondingly connected with the main vanes in the same direction; the length of the main vanes is greater than that of the secondary vanes; the outer ends of the main vanes are provided with a flow stabilization ring surrounding the revolving shaft; an auxiliary vane which is arranged on the flow stabilization ring is arranged between every two adjacent main vanes; the auxiliary vanes are radially arranged from the axle center of the impeller; flow guide vanes are arranged between the main vanes and the auxiliary vanes; flow guide holes are formed between the flow guide vanes and the revolving shaft; the parts, close to the flow guide holes, of the tops of the guide vanes have equal height; and the intersecting lines of the tops of the flow guide vanes and the inner surfaces of the flow stabilization ring are slantly upward to ensure that the tops of the flow guide vanes are inclined surfaces, have the function of pushing and guiding water flow, improve water draining efficiency and pumping head, reduce noise and power consumption.

Description

Air-conditioning draining pump impeller

Technical field

The invention belongs to the draining pump component, especially relevant with a kind of air-conditioning draining pump impeller.

Background technique

The air-conditioning draining pump is to be used for the air conditioner condensate water drainage means.Air-conditioning draining pump impeller on the existing market mainly is made up of rotating shaft and a plurality of primary blades, back blades; Impeller is the axle center with the rotating shaft; Primary blades is radial from the impeller axle center and is installed in the rotating shaft, back blades be installed in rotating shaft the bottom and with the corresponding in the same way connection of primary blades, primary blades length is greater than back blades; The primary blades outer end is provided with the current stabilization ring of twisted rotary shaft; Between two adjacent primary blades auxiliary blade is set, auxiliary blade is installed on the current stabilization ring, and equally with primary blades is radial from the impeller axle center; During use, impeller is placed in the chamber body, and rotating shaft is connected by motor driving with machine shaft rotates; Back blades immerses in the water; Through centrifugal force water is fallen the water outlet on the pump housing sidewall, the stirring of water is promoted the suction pump intracoelomic cavity with water, use such impeller that water is promoted the back water capacity and be prone to return fall and fall through pump housing inside and outside differential pressure and back blades; Make draining pump drain discharge and lift be restricted, drainage efficiency is not high.

Summary of the invention

The object of the invention is exactly limited by impeller in order to overcome existing air-conditioning draining pump drain discharge and lift, the defective that drainage efficiency is not high, and providing a kind of can be that air-conditioning draining pump noise is little, drainage efficiency compares higher impeller.

For this reason, the present invention adopts following technological scheme: air-conditioning draining pump impeller comprises rotating shaft and multi-disc primary blades, back blades; Impeller is the axle center with the rotating shaft; Primary blades is radial from the impeller axle center and is installed in the rotating shaft, back blades be installed in rotating shaft the bottom and with the corresponding in the same way connection of primary blades, primary blades length is greater than back blades; The primary blades outer end is provided with the current stabilization ring of twisted rotary shaft; Between two adjacent primary blades auxiliary blade is set, auxiliary blade is installed on the current stabilization ring, and equally with primary blades is radial from the impeller axle center; It is characterized in that: between described primary blades and the auxiliary blade guide plate is set; Between guide plate and the described rotating shaft space is arranged; Form pod apertures, the guide plate end face is near height such as described pod apertures places, and the intersection of guide plate end face and current stabilization ring inner surface is oblique and makes progress; Make the guide plate end face be the inclined-plane, and the spikes/low-points of adjacent two intersections is adjacent.

When using, the present invention is placed in the draining pump pump housing inner chamber; Rotating shaft is connected with the draining pump motor, and by motor driving impeller rotation, the intersection of the sense of rotation of impeller and guide plate end face and current stabilization ring inner surface is upward on the contrary; Back blades immerses in the water with the water sucking mouth of the pump housing; The centrifugal force that produces through impeller rotation falls the water outlet on the pump housing sidewall with water, through pump housing inside and outside differential pressure and back blades the stirring of water is promoted the suction pump intracoelomic cavity with water, and current rise to the guide plate end face through pod apertures; The rotation of impeller makes the guide plate end face produce propelling movement power upwards to current, accelerates the lifting flow velocity of current at the guide plate end face.

As to the improving and replenishing of technique scheme, the present invention also comprises following technical characteristics.

Described guide plate end face is the circular arc inclined-plane, helps water flow stationary and promotes.

All described guide plate bottom surfaces are connected to level and smooth integral body, reduce the bump of current, reduce noise.

Described primary blades quantity is 4, and corresponding back blades quantity also is 4, and the angle between adjacent two primary blades is 90 degree.

Described rotating shaft is provided with axis hole, is used for being connected cooperation with machine shaft, and shaft hole inner wall is provided with internal spline.

Use the present invention can reach following beneficial effect: through the guide plate with circular arc inclined-plane is set, current to be played the propelling movement guiding function between primary blades and back blades, avoided current to promote the back and fallen after rise; And current promote steadily; Reduce the bump between current and blade and the current stabilization ring, reduced noise, improved drainage efficiency and lift; Reduce power consumption, practice thrift user cost.
