Description
Technical field
The present invention relates to a kind of draining pump, specifically a kind ofly be installed in the drain tank that the condensed water that makes air conditioner stockpiles and the draining pump that condensed water is discharged to the outside.
Background technique
The indoor set of air conditioner, under cooling condition, airborne water vapour is met cold meeting and is condensed into water, just require the condensed water that generates in time is discharged to correct position with draining pump, such draining pump requires to have certain flow and lift, simultaneously by the strict demand of Environmental Conditions, to limit within the specific limits the operating noise of this type of draining pump to the air-conditioning system noise.Chinese patent ZL 95107436.9 disclosed a kind of draining pumps, be by suction port being set in the underpart upper side be provided with discharge opening the pump body, the rotation be accommodated in the intrinsic solid of rotation of said pump freely and above-mentioned solid of rotation motor rotating constituted, above-mentioned solid of rotation has axial region, tabular big footpath blade, tabular path blade, the disk of hollow portion etc. is arranged.This draining pump complex structure, owing to be provided with disk, thus restriction draining pump acting ability has influenced lift and flow and has improved; And these type of draining pump great majority work in off-design behaviour, and as the low water level low lift, the high water level low lift often causes draining pump to be in band water idle running, the mixture of water and air is moved in discharge pipe line repeatedly and can not arrange, thereby produce extra noise.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is to overcome the defective that above-mentioned prior art exists, and the draining pump of a kind of compact structure, no disk is provided, and to improve flow and lift, improves the noise under the off-design behaviour.
The technical solution adopted in the present invention is as follows: a kind of draining pump, be included in the pump housing that the underpart is provided with water intake and sets out the mouth of a river in upper side, place the impeller in the pump housing and make the impeller motor rotating, it is characterized in that described impeller comprises primary blades, be positioned at the short blade between adjacent primary blades, surround the current stabilization ring and the axis part that is connected with motor output shaft of primary blades top outer rim and short blade outer rim, main, short blade is that the center is radial arrangement with the axle center of axis part, the inner edge of primary blades is connected on the axis part, and there is a distance inner edge of short blade and axis part.The present invention has cancelled the setting of disk in the existing draining pump, has avoided the restriction to the acting ability of draining pump, has improved lift and flow.Short blade is connected as a single entity by current stabilization ring and primary blades, and short blade helps reducing secondary flow and the separated flow that primary blades produces, and the length by selected short blade and primary blades changes drain discharge than (promptly changing the size of distance).The current stabilization ring can reduce the generation of nominal situation inferior lobe top place's leakage flow and leakage vortex.When draining pump was in off-design behaviour, primary blades was easy to generate secondary flow, and the secondary flow that the current stabilization ring can suppress to generate has reduced the degree of place, leaf top turbulent flow to the expansion of primary blades outer rim, thereby had reduced the generation of primary blades outer rim noise.
Described draining pump, primary blades are " Γ " shape, are made up of flat acting portion and diversion division, and both are connected as a single entity with curved surface, and the structure processing of integral type is simple, convenient, and material is economized, and connects with curved surface and can avoid generating noise.
Described draining pump, the aspect ratio of acting portion and diversion division (h: be 1: 1～2 H),, just can further change the height and the drain discharge of the draining liquid level of this type of draining pump by changing the aspect ratio of acting portion and diversion division.
Described draining pump, the shape of short blade is consistent with the shape of acting portion opposite position, the length of short blade and primary blades acting portion is than (1: be 0.5～1.0: 1 L), the length by selected short blade and primary blades acting portion changes drain discharge than (promptly changing the size of distance).
Described draining pump, short blade are located on the angle bisector that forms between adjacent primary blades, make between blade balance good, and noise is little.
Described draining pump, the perpendicular distance of the acting subordinate edge of primary blades and the opposite position of pump housing inwall is 0.5～3mm, with flow that reaches further control draining pump and the generation that suppresses the lower edge noise of acting portion, flow and noise is in the zone of reasonableness.
Described draining pump, the diversion division outer rim at 0.5～2mm, is in the zone of reasonableness flow and noise to the distance of the inwall opposite position of pump housing water inlet.
Described draining pump, the perpendicular distance of the opposite position of short blade lower edge and pump housing inwall is 0.5～3mm, with flow that reaches further control draining pump and the generation that suppresses the lower edge noise of short blade, flow and noise is in the zone of reasonableness.
The present invention has following beneficial effect: short blade helps reducing secondary flow and the separated flow that the top of primary blades acting portion produces, and has selected the length ratio of suitable short blade and primary blades acting portion, thereby has changed drain discharge; Short blade is connected with primary blades by the current stabilization ring, and the current stabilization ring can reduce the generation of nominal situation inferior lobe top place's leakage flow and leakage vortex; When draining pump was in off-design behaviour, the current stabilization ring can suppress the secondary flow of primary blades generation to the expansion of blade outer rim, has reduced the degree of vane tip place turbulent flow, thereby has reduced the generation of blade outer rim noise; By regulating the perpendicular distance of short blade lower edge and primary blades acting subordinate edge,, flow and noise are in the zone of reasonableness with flow that reaches further control draining pump and the generation that suppresses the lower edge noise of acting portion to the opposite position of pump housing inwall.
