Abstract
The utility model relates to a water cooling energy saving pump, which comprises a water pump, an electric motor and a hollow motor shaft. Head of the motor shaft between the motor shaft and vane connecting end is provided with a through hole, and the other end of the motor shaft is closed. Cavity of the motor shaft is provided with a hollow tube. One end of the hollow tube is connected tightly with the end of the motor shaft. Gaps are reserved at the other end of the hollow tube and the closed end of the motor shaft to allow the water from the water pump flow through. Outer diameter d of the hollow tube is less than inner diameter D of the cavity of the motor shaft. A hole is opened on the motor shaft where the water pump forms high pressure water chamber. The cavity of the motor shaft is communicated with the high pressure water chamber of the water pump. Heat generated by the electric motor will be taken away during flowing of water in the water pump, and the electric motor of the pump needs no external cooling equipment. The utility model can assure former sealing property of the electric motor without damaging former structure of the electric motor, which extends service life of the equipments, reduces production cost and improves working efficiency.
Description
One. technical field
This novel a kind of water pump, motor shaft that uses in the motor on particularly a kind of water pump of relating to.
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
This novel purpose is: design a kind of novel motor shaft, when reaching pump working, reduce the heat that motor produces by self internal structure, thereby reach the working life of prolongation equipment, reduce production costs the purpose of increasing work efficiency.
The following structure of this novel employing realizes 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.
Four. description of drawings
