Abstract
The invention discloses a low-noise drainage pump comprising a rotating impeller. The rotating impeller comprises a central spindle provided with main blades gradually increasing in diameter from a water inlet to a water outlet, a steady flow ring is fixedly connected with top ends of all the main blades, secondary blades growing shorter and extending to the central spindle are arranged on the steady flow ring and between the main blades, and gaps are reserved between the secondary blades and the central spindle. The low-noise drainage pump produces less air bubbles and low noise under the condition that a certain amount of head and flow are maintained at the same time.
Description
Technical field
The present invention relates to a kind of draining pump, particularly relate to a kind of for getting rid of the low noise water discharge pump as condensed waters such as air-conditionings.
Background technique
Air-conditioning is when refrigeration, and after refrigerant compression, evaporation is gasified, the absorbing environmental heat, and now airborne moisture can condense into water, these condensed waters need to be discharged in time, in order to avoid affect the safe handling of electrical equipment.This water pump of daring to discharging condensed water is arranged on indoor set usually, so require water pump to have outside certain flow and lift, also needs to consider the impact of noise.
In existing design, what the design of this draining pump adopted usually is to arrange and become gradually large blade from water inlet to the water outlet diameter in central rotating shaft, and a current stabilization ring also is set simultaneously, and the current stabilization ring is connected with vaned outermost end.The short blade extended to central rotating shaft also is set in addition on the current stabilization ring, between short blade and central rotating shaft, reserves certain gap.
But the claimant finds, the design of this pump still is difficult to avoid in running, the disturbance that blade causes current and produce bubble, and then produce vibration and the noise of current.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of low noise draining pump, to reduce the generation of stream nucleus in the pump operation process, and then reduce noise.
Technological scheme of the present invention is such: a kind of low noise draining pump, comprise rotary blade, it is characterized in that: described rotary blade comprises central rotating shaft, described central rotating shaft is provided with from water inlet and becomes gradually large primary blades to the water outlet diameter, the current stabilization ring is fixedly connected with the top of all primary blades, also be provided with the height extended to central rotating shaft and become gradually short inferior blade on the current stabilization ring between described primary blades, between described blade and central rotating shaft, leave gap.
Preferably, described primary blades quantity is six.
Preferably, described blade is on the bisector of the angle between adjacent primary blades.
The advantage of technological scheme provided by the present invention is, the current stabilization ring can stop the current direction blade tip diffuse outside that primary blades forms to guarantee flow and lift, between primary blades, arrange time blade to by the current stabilization loop resistance, disturbed current with secondary, advance, become highly gradually short inferior blade and can effectively stop original blade to produce the problem of bubble when advancing current, reduce the generation of noise.
The accompanying drawing explanation
Fig. 1 is rotary blade structural representation of the present invention.
Fig. 2 is rotary blade structure plan view of the present invention.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but not as a limitation of the invention.
Refer to Fig. 1, the low noise draining pump, comprise rotary blade, rotary blade comprises central rotating shaft 1, be provided with six primary blades 2 that become gradually large from water inlet to the water outlet diameter in central rotating shaft 1, current stabilization ring 3 is fixedly connected with the top of all primary blades 2, also is provided with the height extended to central rotating shaft and becomes gradually short inferior blade 4 on the current stabilization ring 3 between primary blades 2,1 of inferior blade 4 and central rotating shaft leave gap, and inferior blade 4 is on the bisector of the angle between adjacent primary blades 2.
