Abstract

An energy-saving water-cooling water pump comprises a motor, a pump body, and an impeller, wherein the motor has a hollow motor shaft; the motor shaft has a via-hole end connected with the impeller and a closed end; a hollow tube is arranged in the hollow cavity of the motor shaft; the hollow tube is sealed with the via-hole end of the motor shaft, and keeps a gap with the closed end for allowing water to flow; the outer diameter of the hollow tube is smaller than the inner diameter of the hollow shaft; holes are formed on the shaft and the impeller at the connection joint of the motor shaft and the impeller; and back blades are also arranged on the impeller.

Description

Water-cooled energy-saving water pump
One: technical field
This novel a kind of water pump, particularly a kind of energy-saving water pump of relating to.
Two: background technique
In the prior art in order to solve the problem of water pump internal heat dissipating, the general method that adopts is that the axle with pump motor is processed as hollow structure, in the middle of the axle of hollow, hollow tube is installed, pressure by the pump outlet hyperbaric chamber flows the formation in the middle of motor shaft of part water, get back to low-pressure cavity then, reach the purpose of cooling motor with this, because the space itself in the motor shaft is just very little, resistance when at this moment water flows is just bigger, it requires just than higher the pressure of water pump hyperbaric chamber, very strong according to patience, just do not reach cooling purpose if pressure is little, thereby influence the using effect of pump.
Three: summary of the invention
This novel purpose is: design a kind of motor shaft water and come hydronic water pump, and the pressure of disobeying water-fast pump hyperbaric chamber during cooling circulates and reaches cooling purpose, thereby reduce the pump motor temperature inside, promote the utilization efficiency of water pump, reach the purpose energy-conservation and reliability that the raising water pump uses.
The following structure of this novel employing realizes above-mentioned purpose, a kind of water-cooled energy-saving water pump, comprise: motor, the pump housing, impeller, motor shaft is a quill shaft, wherein motor shaft and impeller connecting end are through hole, the other end is sealing, in the hollow cavity of motor shaft hollow tube is installed, the through hole end of hollow tube and motor shaft forms sealing, leave the gap that water is flow through with closed end, the external diameter of hollow tube is less than the internal diameter of motor quill shaft, has the hole on the axle of motor shaft and impeller joint and impeller, and back blade also is installed on impeller.
Adopt structure as above, the inner problem that produces heat when having solved the motor operation, thereby the efficient when having improved the pump motor operation, the energy that has expended when having saved operation, water pump in the process of operation because back blade has been installed on impeller, when the motor high speed rotating, impeller runs up simultaneously, impeller drives back blade and runs up, when back blade runs up since action of centrifugal force the water throwing around it can be held, make its local vacuum state that forms, since the no-man's-land the axle and impeller on have the hole, when producing vacuum, because atmospheric pressure causes into water by flowing in motor shaft in the hollow tube in the motor shaft, then by the zone of high pressure of the orifice flow between axle and impeller to pump, by back blade water is beaten away again, water is taken away the motor heat when flowing simultaneously, reduced the temperature rise of motor, improved efficiency of motor, reached effective purpose of energy saving, this is because because the motor temperature rising, can cause resistance to raise simultaneously, resistance raises and causes loss to increase, and the loss increase causes decrease in efficiency, power consumption increases, and opposite motor temperature reduces its efficient and just increases.
Four: description of drawings
Fig. 1 is this novel sectional drawing
Five: embodiment
As shown in the figure, water-cooled energy-saving water pump, comprise: motor 1, the pump housing 2, impeller 3, back blade 4, motor shaft 5 has hollow cavity 6, wherein motor shaft 5 is a through hole 7 with the connecting end of impeller 3, the other end is a closed end 8, hollow tube 9 is housed in the hollow cavity of motor shaft 5, and through hole 7 ends of an end of hollow tube 9 and motor shaft 5 are connected to form sealing 10, and the other end of the other end of hollow tube 9 and motor shaft 5 leaves the gap 11 that water can be flow through, the outside diameter d of hollow tube 9 is less than the internal diameter of the hollow cavity 6 of motor shaft 5, the joint of motor shaft 5 and impeller 3 has hole 12, and the hollow cavity 6 of motor shaft 5 and water pump hyperbaric chamber 13 are communicated, and hollow tube 9 is to have hollow 14 hollow tubular.
Back blade 4 is installed on water pump vane 3, when running up, back blade 4 forms vacuum bands 15 owing to action of centrifugal force makes hyperbaric chamber 13 parts, because vacuum band 15 and motor shaft 5 form and are communicated with, make the hollow parts of motor shaft 5 also form vacuum, utilize the principle of atmospheric pressure to make the water of impeller 3 water intakes 16 flow to hollow tube 9 by logical empty 7, the other end of the other end by hollow tube 9 and motor shaft 5 leaves the hollow cavity 6 that makes the gap 11 flow direction motor axles 5 that water can flow through again, the hole 12 of the joint by motor shaft 5 and impeller 3 flows to vacuum band 15 again, thereby fill a vacuum the space, water has back blade 4 to drain again, water is formed in motor shaft 5 to flow, motor and bearing are cooled off, to reach the purpose of this patent.
Arrow is the flow direction of water in motor shaft 5.
