Abstract
The invention discloses an automatic cooling system for a bulb tubular pump synchronous motor. The automatic cooling system comprises an air circulation system and a water circulation system. According to the air circulation system, cold air produced by a cooling fan is blown to a stator and a rotor, heat produced by the stator and the rotor is taken away to convert the cold air into hot air, and the hot air is sucked by the cooling fan, and performs heat exchange with cooling water in an air cooler when passing through the air cooler to be converted into the cold air. According to the water circulation system, the cooling water in the air cooler is converted into hot water after the heat exchange with the hot air, the hot water is driven by a circulating water pump to enter a water circulator, and performs heat exchange with water in a water passage outside a motor shell to be converted into cold water, and the cold water enters the air cooler. According to the automatic cooling system, investment in a bulb tubular pump can be lowered, and the working space of an overboard cooling tower can be reduced.

The technical scheme of the cooling system voluntarily of bulb-type tubular through flow pump synchronous machine of the present invention; Adopt motor to carry the outer cooling tower of machine that water cooler has replaced prior art; Can reduce the investment of bulb-type tubular through flow pump and the working space of the outer cooling tower of machine, have considerable economic.
Description of drawings
Fig. 1 is the structural representation of the cooling system voluntarily of bulb-type tubular through flow pump synchronous motor of the present invention.
Embodiment
Below through concrete embodiment and combine accompanying drawing that technical scheme of the present invention is described:
See also Fig. 1, bulb-type tubular through flow pump synchronous machine is installed in the water flow passage 1, and this water flow passage 1 has a shell 10.Wherein, the stator 21 of motor is installed in the totally enclosed electric machine casing 2 with rotor 22; The impeller 23 of tubular through flow pump is installed in the front portion of the housing 2 of motor; An aerial cooler 3 is installed at the inner chamber rear portion of electric machine casing 2, and the rear end of this aerial cooler 3 is equipped with cooling blower 4; The outer water cooler 5 of installing of the tail end of electric machine casing 2, the hot water inlet of this water cooler 5 is connected through hot water pipeline 50 with the hot water outlet of aerial cooler 3, on this hot water pipeline 50 circulating water pump 6 is installed; The cooling water outlet of water cooler 5 is connected through cold water pipes 30 with the cooling water inlet of aerial cooler 3.
The operation principle of aerial cooler is that high temperature air gets into aftercooler from air inlet, flows between the heat exchanger tube in core body, and it and the interior cooling water of cooler casing carry out heat exchange, and temperature is reduced, and flows out from the gas outlet.Cooling water gets into cooler casing from the cooling water inlet of aerial cooler, carries out discharging from the hot water outlet of aerial cooler after the heat exchange with high temperature air.
The operation principle of water cooler is that the hot fluid in the pipe carries out heat exchange through the cooling water outside tube wall and fin and the pipe.
The cooling system voluntarily of bulb-type tubular through flow pump synchronous machine of the present invention comprises air circulation system and water circulation system, wherein,
Air circulation system blows to stator 21 and rotor 22 for the cold wind 41 that is produced by cooling blower 4 and takes away stator 21 and the heat of rotor 22 generations; Make cold wind 41 become hot blast 42; Be cooled blower fan 4 of this hot blast 42 sucks; During through aerial cooler 3 and the cooling water in the aerial cooler 3 carry out heat exchange, make hot blast 42 become cold wind 41 again;
The water circulation system cooling water 51 that gets in the aerial cooler 3 of serving as reasons has become hot water 52 after carrying out heat exchange with hot blast 42; This hot water 52 gets into water cooler 5 through the driving of circulating water pump 6; Carry out heat exchange with the current 11 in electric machine casing 2 water flow passage 1 outward; Make the hot water 52 that gets into water cooler 5 become cold water 51 again, this cold water 51 gets in the aerial cooler 3 again.
