Abstract

The utility model discloses an impeller of air-conditioning draining pump, belonging to parts of draining pump. The existing air-conditioning draining pump has the defects of restrictions of impellers to drainage flow and lift and not high draining efficiency. According to the utility model, the impeller of air-conditioning draining pump comprises a shaft, a plurality of main blades and back blades; the shaft serves as the axis of the impeller; the main blades are radially installed on the shaft from the axis of the impeller; the back blades are installed at the bottom of the shaft and correspondingly connected with the main blades; the main blades are longer than the back blades; constant-current rings are arranged at the outer end of the main blades and surround the shaft; auxiliary blades are disposed between two adjacent main blades and installed to the constant-current rings; the auxiliary blades are radially arranged from the axis of the impeller; flow deflectors are arranged between the main blades and the auxiliary blades; deflector holes are arranged between the flow deflectors and the shaft; the top surfaces of the flow deflectors closing to the deflector holes are equally high; and the intersection line of the top surfaces of the flow deflectors and the inner surfaces of the constant-current rings is obliquely upward so that the top surfaces of the flow deflectors are inclined planes to push and guide water flow. According to the utility model, the impeller improves the draining efficiency and lift, and reduces noise and energy consumption.

Description

Air-conditioning draining pump impeller

Technical field

The utility model belongs to the draining pump component, and is 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.

The model utility content

The purpose of the utility model 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 utility model 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.

The utility model is placed in the draining pump pump housing inner chamber when using; 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 utility model 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 utility model 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.
