Description
Technical field
This model utility relates to a kind of pump cover of split-pole water pump, belongs to the technical field of split-pole water pump.
Background technique
The existing split-pole water pump that is used for top suction type central air-conditioner drainage system mainly is made of the pump housing and the pump cover that is sealedly connected on the pump housing, is arranged on motor with cup rotor in the pump housing, on the motor with cup rotor axle impeller is installed.When motor with cup rotor drove the impeller rotation at a high speed, water pump in the gap of intake pipe suction pump leaf and pump cover, made condensation flow discharge along pump leaf sense of rotation flow at high speed air conditioner condensate water.But condensed water is under action of centrifugal force, condensed water flows along the tangent to periphery direction of pump cover inwall at a high speed, so the condensed water that causes part to enter in the pump cover flies out and circulates in pump cover along the tangent to periphery direction of pump cover inwall, therefore the condensed water that flows through the effluent pipe mouth place is discharged fully, and influence drainage efficiency.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, and can improve the pump cover of the split-pole water pump of split-pole water pump drainage efficiency.
The utility model is that the technological scheme that achieves the above object is: a kind of pump cover of split-pole water pump, the bottom of described pump cover has the intake pipe of downward extension, the annular solid of pump cover has outward extending outlet pipe, it is characterized in that: the water-blocking groove that the inwall of described annular solid is provided with indent and communicates with the outlet pipe mouth of pipe along the current sense of rotation.
The utility model is at the water-blocking groove that only is provided with indent on the basis of former pump cover on the inwall at annular solid, and is simple in structure, promptly is convenient to make, and do not influence the mechanical strength of pump cover again.When condensation flow with pump leaf high speed rotating during flow at high speed, under action of centrifugal force, the condensed water high speed flies out along the inwall tangent to periphery direction of the side ring body of pump cover, when current flow in the water-blocking groove with coherence, converge rapidly by water-blocking groove on the one hand and amass condensed water, and rapidly by condensed water being discharged smoothly by waste pipe with water-blocking groove.On the other hand, by water-blocking groove condensed water is flowed along the tangent to periphery direction of the side ring body inwall of pump cover, and can not circulate in pump cover, therefore improved the drainage efficiency of split-pole water pump greatly, lift and flow all can improve more than 1.2 times.The utility model is owing to improved the drainage efficiency of split-pole water pump, under equal water level condition, owing to improved the water displacement of split-pole water pump unit time, shortened the drainage works time of water pump, the motor with cup rotor temperature rise also can correspondingly be descended, the split-pole water pump that slowed down decay, the working life of prolongation split-pole water pump.
