The invention relates to a high temperature hot water pump, which comprises an upper end cover (1), an enclosure (3) with a radiating fin, a stator (5), a wind guiding sleeve (4), machine oil (5), a rotator (6), a lower bearing block (8), a mechanical seal (9), a fan (11), a pump (13) and a wire holder (14) with a seal, wherein the above components form a motor in which the machine oil rapidly circulates for heat exchange; the lower end of the rotator (6) is provided with the fan; the pump conveys temperature of the high temperature water to the motor, then the temperature in the motor is rapidly passed to the enclosure with the radiating fin and the lower bearing block through the machine oil; and the fan does work to rapidly bring the temperature of the enclosure with the radiating fin and the lower bearing block to the air so as to achieve the limited cooling effect; and meanwhile, the bearing always keeps excellent lubrication operation state, the motor efficiency of the pump is improved, and the service life of the pump is prolonged.
Description
Technical field
The present invention relates to a kind of high temperature hot water pump, belong to the plumbing field.
Background technique
For a kind of high temperature hot water pump, its type of cooling and structure are very important.
Conventional high temperature hot water pump, its structure comprises standard ventilated machine, pump cover, mechanical seal and water pump.
In the high temperature hot water pump running, the heat of motor internal is taken away by the radiating fin of the wind flow cooling motor shell appearance of the last fan work of motor fully, reaches the purpose of cooling motor.
Shortcoming: during pump working, the water of its conveying is high-temperature water, because the Bearing support pump is very near below the motor, water high temperature is delivered to bearing and rotor very soon by motor shaft, because the structural relation of standard electromotor, following bearing portion can't be subjected to the distinguished and admirable cooling of fan, and so bearing temperature increases severely, and the very fast liquefaction of its lubricating grease is run off and made bearing do operational damage, the quick rising of temperature of rotor simultaneously, electric efficiency obviously can be reduced, and insulation ag(e)ing is accelerated, and electrical machinery life shortens.
Summary of the invention
The object of the present invention is to provide a kind of high temperature hot water pump, the particular design of this water pump structure and improvement reduce high temperature hot water pump motor internal temperature greatly, improve the water pump purpose in working life thereby reach, and can raise the efficiency Synergistic and energy-saving.
In order to achieve the above object, solution of the present invention is: this water pump comprises upper end cap (1), band radiating fin casing (3), stator (5), wiring base (14), sealing (15), air guiding sleeve (4), machinery oil (5), rotor (6), step (8), mechanical seal (9), band sealing machine sealing gland (10), fan (11), pump cover (12), water pump (13).
During water pump operation, because the water that water pump is carried is high-temperature water, the high temperature of water can be delivered to the component such as machinery oil, bearing and rotor of mechanical seal periphery by rotor axis of electric, make the machinery oil rapid movement by its two ends blade during the rotor rotation, the motor internal temperature is accelerated to transmit by machinery oil, electric machine rotor itself is because the generation temperature of also can generating heat such as losses simultaneously, the temperature that both produced all can pass to machinery oil fast, and passes to flange-cooled motor casing, step by machinery oil.Rotor shaft drives the fan acting during pump working, generation has the wind of enough flows, pressure energy, wind is along the mobile fast work of arrow direction as shown in Figure 1, on the one hand below the cooling fan and the motor shaft between the pump cover, reduce the portion temperature of axle, make the temperature that reduces any pass through axle toward top transmission.Fast cooling reduces by machinery oil and is delivered to temperature on motor band radiating fin casing, the step on the other hand, its heat is taken in the air of air guiding sleeve outside by wind energy fast, make so whole this high temperature water pump upper motor temperature can not carry the high-temperature water motor temperature and rise rapidly that temperature is lower when carrying the normal-temperature water operation than standard pump on the contrary because of water pump.
Pump motor internal rotor metal (upper not de-oiling all the time work, following spherical bearing is immersed in the machinery oil all the time works, consider that oil expands at a certain temperature, the too high generation of internal oil pressure is dangerous, therefore institute adds machinery oil and can not have one's bosom filled with in the motor, oil level is in position, upper bearing (metal) lower edge, the above-mentioned work that has been mentioned to rotor blade can make the machinery oil rapid movement, and can move upward, so upper bearing (metal) also can be accomplished not de-oiling work all the time, and machinery oil also can enter into upper bearing (metal) circulating lubrication and cooling by two holes above the upper end cap bearing.
Beneficial effect of the present invention: under same load, water pump can hang down 5-10 ℃ when carrying high-temperature-hot-water motor internal temperature comparison with standard motor to carry the normal-temperature water operation, and greatly prolong working life, and efficient can improve 0.8-1.5%.
Below in conjunction with accompanying drawing and example the present invention is made comparisons and to explain.
