Abstract
The invention discloses a water-cooling energy-saving water pump, which comprises a water pump and a motor. Wherein, the motor axle is hollow, whose end that connected to the blade wheel is a through hole, another end is sealed; the hollow chamber of motor axle contains a hollow tube whose one end is connected to the motor axle that has through hole to form sealing, and another end has a slit between the motor axle that with sealing end to flow water; the outer diameter d of hollow tube is small than the inner diameter D of motor axle; the motor axle has holes at the part of high-pressure water chamber, to connect the hollow chamber and the high-pressure water chamber. The invention can utilize the flow of water to discharge the heat generated by motor and avoid external temperature reducer. And it can be processed without changing former structure of motor, to confirm the sealing property. The invention can prolong the service life, reduce the producing cost and improve the working efficiency.
Description
One. technical field
The present invention relates to a kind of water pump, the motor shaft that uses in the motor on particularly a kind of water pump.
Two. technical background
Pump motor in the market, because motor can generate heat in using, thereby to motor need the cooling, the method of cooling has a variety of, adopts the fan blade cooling usually, though can reach cooling purpose, but caused the unnecessary wasting of resources, and the motor feels hot when being work, and its internal structure produces, adopts air-cooled can only be in the cooling of motor outside, so the effect of cooling off is unsatisfactory.The employing water-cooling pattern is also arranged, and generally is by the cooling motor shell, thereby reaches the purpose of cooling motor.During machine operation, the motor shaft high speed rotating, the heat of motor internal is depended merely on outside cooling and not can solve the living heat problem of motor, and motor normally drives pump working, the sealing of motor is again very important, thereby people are seeking a kind of solution always and how can keep the motor good sealing property, can solve motor internal again and give birth to heat problem, improve the method for the working efficiency of motor.
Three. summary of the invention
The objective of the invention is to: design a kind of novel motor shaft, when reaching pump working, reduce the heat that motor produces, thereby reach the working life of prolongation equipment, reduce production costs the purpose of increasing work efficiency by self internal structure.
The present invention adopts following structure to realize above-mentioned purpose: a kind of water-cooled energy-saving water pump, comprise water pump, motor, motor shaft is a quill shaft, wherein the motor shaft end of motor shaft and impeller connecting end is a through hole, another motor shaft end is sealing, in the hollow cavity of motor shaft hollow tube is housed, hollow tube one end is connected to form sealing with the motor shaft end of band through hole, the hollow tube the other end leaves with the motor shaft end of being with closed end can make the gap that water flows through in the water pump, the outside diameter d of hollow tube is less than the hollow cavity inside diameter D of motor shaft, motor shaft forms the high-pressure water chamber place at water pump and has the hole, and the hollow cavity of motor shaft is communicated with water pump formation high-pressure water chamber place, and hollow tube is with hollow hollow tubular.The motor shaft end of band closed end adopts the sealing screw sealing, forms the closed end of motor shaft.The hollow cavity of motor shaft is until the motor shaft in the bearing 1.Motor shaft forms the high-pressure water chamber place at water pump and has a plurality of holes.
Adopt said structure, solved motor internal and produced hot problem, promptly kept the proper functioning and the good sealing property of motor, improved the working efficiency of motor again, water pump can make the water in the motor shaft constantly flow at work by its internal structure, thereby reaches the purpose of heat radiation.Because water pump itself is that pump intake pressure is low, water outlet pressure height, in pump body, there are high-pressure water chamber and low pressure water cavity, motor shaft forms the high-pressure water chamber place and has the hole in pump body, the hollow cavity of motor shaft is communicated with formation high-pressure water chamber place in the pump body, utilize the pressure reduction in the pump body, water in the water pump enters in the passage that the cavity of motor shaft and hollow tube form by the hole on the motor shaft, water in the water pump is by the gap of hollow tube with the motor shaft end of band closed end, flow in hollow tube hollow, the hollow low pressure water cavity place that flows to water pump by hollow tube, flow out together from pump outlet at last,, motor and bearing are cooled off in the place that water flows through because the water in the water pump flows in the motor shaft simultaneously, the heat that motor produces is pulled away by current, to reach the purpose of this patent.Water pump had both been finished the work of water pump when work like this, water in the motor shaft is constantly flowed, utilize the fluxion strap of water in the water pump to walk the heat that motor self produces, motor on the water pump does not need the outside to increase cooling system again, and both can finish not damaging under the original motor structure situation, well guaranteed the existing sealing of motor.Prolonged the working life of equipment, reduced production costs, increased work efficiency.

Five. embodiment
As shown in the figure, water-cooled energy-saving water pump, comprise water pump 16, motor 7, motor shaft 2 has the quill shaft of hollow cavity 4, wherein motor shaft 2 is a through hole 13 with the motor shaft end of impeller 12 connecting ends, another motor shaft end is a closed end 15, hollow tube 5 is housed in the hollow cavity of motor shaft 2, hollow tube 5 one ends are connected to form sealing 10 with the motor shaft end of band through hole 13, hollow tube 5 the other ends leave the gap 14 that water is flow through with the motor shaft end of band closed end 15, the outside diameter d of hollow tube 5 is less than the inside diameter D of hollow cavity 4 in the motor shaft 2, motor shaft 2 has hole 8 in the high-pressure water chamber position of pump body 16, the hollow cavity 4 of motor shaft 2 is communicated with water pump 16 formation high-pressure water chamber places, and hollow tube 5 is to have hollow 6 hollow tubular.
In pump body 16, there are high-pressure water chamber 9 and low pressure water cavity 11, on the motor shaft 2 of water pump high-pressure water chamber position, have hole 8, the hollow cavity 4 of motor shaft 2 is communicated with formation high-pressure water chamber place in the pump housing 16, utilize the pressure reduction in the pump body 16, water in the water pump 16 enters in the hollow cavity 4 of motor shaft 2 by the hole on the motor shaft 28, the gap 14 that water in the water pump 16 forms by the motor shaft end that flows to hollow tube 5 and band closed end 15, flow to again in the hollow body 6 of hollow tube 5, flow to low pressure water cavity 11 places of water pump 16 by hollow 6 of hollow tube 5, flow out together from pump outlet at last, because the water in the water pump flows in the motor shaft 2 simultaneously, in the place that water flows through motor and bearing are cooled off, to reach the purpose of this patent.
The motor shaft end of band closed end 15 also can adopt the sealing of sealing screw (not shown), forms the closed end of motor shaft.
The hollow cavity 4 of motor shaft 2 can make the generation of bearing 1 by the mobile reduction heat of water in the motor shaft like this until motor shaft 2 places in the bearing 1 make the hollow tube 5 and the gap 14 of the motor shaft end formation of band closed end 15 be positioned at bearing 1.
Arrow is the water (flow) direction that enters into motor shaft 2.
