The utility model can convey hot and cool liquid, and has the advantages of good radiation result and long life span.
Description
Technical field
The utility model relates to a kind of suction booster, especially a kind of multipurpose suction booster.
Background technique
Pump is a kind of machinery of fluid transfer, in industrial and agricultural production, used widely, suction booster is a kind of of numerous oil hydraulic pumps, use very general, centrifugal booster pump is a kind of in the suction booster, it is to be rotated by the driven by motor centrifugal impeller, reach transmission and supercharging purpose, suction booster often needs the long-time continuous operation in the using process, so to itself the heat radiation requirement than higher, some suction booster is owing to the bad phenomenon of burning motor of heat radiation itself also happens occasionally in operation, though some suction booster the motor tail add a fan strengthen the heat radiation, also play certain effect, it directly arranges the heat of motor afterbody to the external world, but the heat of inside promptly can not be discharged, efficient will descend when service time was long; The supercharging of using at present can only be used for to the liquid supercharging under normal temperature or the low temperature in addition, can not give the liquid supercharging of higher temperature, because when giving the pressurization of higher temperature liquid, the heat of liquid can be transmitted on the motor by the pump housing, the motor internal temperature is raise, the liquid heat is scattered and disappeared in a large number, also caused working efficiency decline, even the danger of burning motor is arranged.
The model utility content
The purpose of this utility model is to provide a kind of multipurpose suction booster, is not only applicable to normal temperature and cryogenic liquide, also applicable to high-temp liquid, has good heat dissipation effect, the characteristics of long service life.
For achieving the above object by the following technical solutions:
A kind of multipurpose suction booster is made up of motor, support, the pump housing, it is characterized in that: the stator outer surface of motor has ventilation slot, and the motor housing outer with stator forms ventilation flue; Be provided with heat-proof device between the motor and the pump housing, heat-proof device is provided with outgassing groove.
Described heat-proof device is the plastics heat insulation rings.
The direction of described ventilation slot is identical with the machine shaft direction.
The bottom land of described ventilation slot has little groove.
During work, motor rotates the fan that drives the motor afterbody, here the fan air blowing direction of Cai Yonging is to blow to motor internal, electric fan directly blows to motor internal with the cool air in the external world, pass from the ventilation flue between stator and the shell, then heated hot air heated is discharged from the outgassing groove on the heat-proof device, adopt said structure to increase contacting of stator surface and air, accelerate the velocity of liquid assets of surperficial air, reached better cooling effect; Between the motor and the pump housing, be added with heat-proof device in addition, can guarantee that pump when transmission higher temperatures liquid, can not conduct heat on the motor, avoid the motor internal temperature to raise, cause burning the generation of motor phenomenon; Also reduced scattering and disappearing of heat in the transmission course simultaneously.Ventilation flue provided by the utility model and heat-proof device, the heat radiation that has improved suction booster is not only applicable to normal temperature and cryogenic liquide, also applicable to high-temp liquid, reaches a pump and uses more.In addition, its motor better heat radiating effect has prolonged working life of pump greatly.

Embodiment
Heat-proof device in the present embodiment adopts the plastics heat insulation ring, and as shown in Figure 1, 2, a kind of multipurpose suction booster is made up of motor 1, the pump housing 2, support 4; Be added with plastics heat insulation ring 3 between the motor 1 and the pump housing, plastics heat insulation ring 3 is provided with outgassing groove 31 and screw 32; Shown in Fig. 2,3, motor 1 comprises casing 11, fan 12, stator 13 and rotor 14 compositions, have several ventilation slots 131 at stator surface, ventilation slot 131 is parallel to machine shaft 16, evenly distribute, casing 11 is close to stator 13 surfaces, forms ventilation flue 15 with ventilation slot on the stator 13 131, and the outgassing groove 31 of ventilation flue 15 and plastics heat insulation ring 3 communicates.
Another embodiment that the utility model provides as described in Figure 4, has several little grooves 1311 in the bottom of the ventilation slot 131 of stator 13, thereby has increased stator 13 surface and ambient air area of contact, helps more dispelling the heat.
During work, motor 1 rotates and drives impeller in the pump housing 2, realizes fluid transfer and supercharging purpose, and the fan 12 that motor 1 rotating shaft simultaneously also drives afterbody rotates, and cool ambient air is blowed to ventilation flue 15; Ventilation flue 15 has increased the area of contact of motor 1 and air, and fan 12 accelerated the velocity of liquid assets of air, when cool air becomes hot air in ventilation flue 15, will take away a large amount of heats, reaches good cooling effect.In addition when transmitting the liquid of higher temperature, because the existence of plastics heat insulation ring 3 can be transmitted on the motor heat hardly, has so both effectively prevented the rising of motor temperature, guaranteed that also the liquid heat can not scatter and disappear in a large number, realized the multiduty function of the hot and cold liquid of transmission.
Claims (4)
1, a kind of multipurpose suction booster, comprise motor, support, pump housing composition, it is characterized in that: the stator outer surface of motor has ventilation slot, stator also is with motor housing outward, ventilation flue on motor housing and the stator forms vent hole, be provided with heat-proof device between the motor and the pump housing, heat-proof device is provided with outgassing groove.
2, a kind of multipurpose suction booster as claimed in claim 1, it is characterized in that: described heat-proof device is the plastics heat insulation rings.
