Embodiment
A kind of heat energy pump, comprise motor, pump case, impeller, water-collecting machine and shell, it is characterized in that: water-collecting machine is arranged on cover top portion, the bottom of shell connects pump case, shell is double-deck, in the internal layer of shell, motor is installed, motor shaft is connected with the impeller be arranged in pump case, the inner layer wall of motor housing and shell is close to, an overcurrent chamber is formed between the bilayer of shell, water-collecting machine central authorities are provided with water intake, have the attachment hole be communicated with overcurrent top of chamber bottom it, have attachment hole to be communicated with the water inlet of pump case bottom overcurrent chamber.The axle of motor is that quill shaft is provided with honeycomb duct in quill shaft, honeycomb duct is positioned at quill shaft, the top being positioned at quill shaft at honeycomb duct offers an opening, the opening of honeycomb duct lower end stretches out the top of motor shaft, the quill shaft of motor is offered an opening, opening is positioned at the water inlet of pump case, and opening inner side is communicated with in quill shaft.In the bearing mounting base of motor shaft, be provided with cooling chamber (not drawing in figure), cooling chamber be provided with machine oil and inject the mouth of pipe (figure does not draw).In overcurrent chamber, be provided with some guide plates (not drawing in figure), in the shape of a spiral, guide plate extends from overcurrent top of chamber toward bottom guide plate.Guide plate is 245 ° from the angle of swing that overcurrent top of chamber extends toward bottom, and the height of guide plate is 1/7 of overcurrent chamber thickness, and the thickness of guide plate is 1/3 of the height of guide plate.The pitch of guide plate is cumulatively taper to again bottom to centre from top, and namely the pitch at two ends is cumulative toward centre.
As shown in Figure 1: motor 1, pump case 2, impeller 3, water-collecting machine 4, shell 5, the internal layer 13 of shell, motor 1 is connected with pump case 2 with water-collecting machine 4 respectively, overcurrent chamber 6 is formed between shell 5 and internal layer 13, impeller 3 is arranged in pump case 2, the axle of motor 1 is connected with impeller 3, water-collecting machine 3 has attachment hole 7, chamber 8 of confluxing is formed between pump case 2 and motor 1, in overcurrent chamber 6 with conflux between chamber 8 and have water inlet 9, water-collecting machine 4 also has water inlet pipe mouth 10, such water source enters into equipment of the present invention by water inlet pipe mouth 10, then overcurrent chamber 6 is entered into by attachment hole 7, impeller 3 is entered into again by water inlet 9, by impeller 3, fluid pressurization is transported to use user, because internal layer 13 surrounds by the liquid flowing through overcurrent chamber 6, and motor housing and internal layer 13 wall are close to, therefore the heat produced when motor 1 works just to heat the liquid flow through by internal layer 13 and reaches the energy-conservation object of heat energy recycle, effective cooling can be carried out to thermal hardware motor 1 again simultaneously, ensure that thermal hardware normally works because thermal hardware eliminates radiation fan with this.
When the motor shaft of motor 1 adopts hollow design, opening 11 is offered at the motor shaft of motor 1, honeycomb duct 12 is installed in motor shaft, water enters into the axle of motor 1 by opening 11, flow from quill shaft toward the top that pressure is little, honeycomb duct 12 is flowed into again from the top of honeycomb duct 12, finally from the top of the opening outflow motor axle of honeycomb duct 12 lower end, the heat collection of inner rotator when motor 1 will be run like this is taken away, and reaches to extend bearing life and stop bearing grease melt and produce noise.Certainly in certain circumstances, the axle of motor 1 also can not adopt hollow structure.
Machine oil can be injected in cooling chamber in the bearing mounting base of motor shaft, open the injection mouth of pipe, by the cooling chamber in machine oil injection bearing fitting seat.So also can by electric machine rotation time, the heat that bearing produces is absorbed by cooling chamber, and is transmitted in the current flow through, and can reduce the operating temperature of bearing, also can increase got heat.
In overcurrent chamber, be provided with some guide plates (not drawing in figure), in the shape of a spiral, guide plate extends from overcurrent top of chamber toward bottom guide plate.Guide plate is 245 ° from the angle of swing that overcurrent top of chamber extends toward bottom, and the height of guide plate is 1/7 of overcurrent chamber thickness, and the thickness of guide plate is 1/3 of the height of guide plate.After being provided with guide plate, current, when by overcurrent chamber, operate steadily, and the noise that its current produce reduces greatly, and in the guide plate test carrying out different radical, its noise reduces 50% with not adding to compare.And the pitch that have employed guide plate is the cumulative bottom that tapers to centre from top, namely the pitch at two ends cumulative toward centre after, be that current are smooth-going more, it reduces noise and does not add guide plate and compare and reduce 60%.
For the thermal cycle water pump of a conventional 75kw, run 1 year=75kw*860 kilocalorie heat (heat that the kilowatt-hour produces) converting heat rate=508518000 kilocalorie heat of * 24 hours * 365 days * 90%, be equivalent to the heating value of 100 tons of coals.Can see thus, realization of the present invention can reduce energy consumption greatly, realizes energy-saving and emission-reduction.
