Description
Technical field
The utility model relates to a kind of pump, specifically is a kind of shielded pipeline pump.
Background technique
Pump is existing common equipment, the all trades and professions of extensive use society, current suction booster mainly comprises pump case, motor, end cap, impeller and fan, pump case, mechanical seal and end cap group one pump housing, impeller is fixed in the rotating shaft of motor, work is rotated by motor rotation impeller liquid is introduced from the inlet opening, extrudes from delivery outlet; Unavoidably produce heat in the pump work process, just heat radiation is difficult to reach favorable cooling effect by fan, therefore current most suction boosters can not carry out long continuous operation, and the main motor of the heating component of pump, as long as solve the heating problem that motor cooling problem has also just solved pump.Rub between the machine shaft and the pump housing in addition, rotating shaft in use is easy to wear, causes mechanical seal bad, causes and leaks, and influences the overall performance of pump.
The model utility purpose
The purpose of this utility model provides a kind of shielded pipeline pump that adopts water-cooled, it is little not have between mechanical seal arrangement and machine shaft and the pump housing friction, has that good cooling results, noise are low, wearing and tearing little, no leakage, long service life and a high reliability features between parts.Adopt following skill scheme for achieving the above object:
A kind of shielded pipeline pump comprises pump case, motor, end cap and impeller, the pump case and end cap group one pump housing, and motor comprises rotor and stator, impeller is fixed in the rotating shaft of rotor; It is characterized in that: between the stator of motor and rotor, be provided with a housing, and in the rotating shaft of rotor, offer exhalant canal, the housing opening is provided with the shielding cover that matches with it, shielding cover is provided with the water inlet, the bottom of housing also is provided with a bearing chamber that cooperates with the rotor shaft phase inversion, bearing chamber and housing are integrated, have the through hole that the pavilion axle for rotor passes in described shielding cover center.
Be provided with graphite bearing in the described bearing chamber.
The rotating shaft of described rotor is that stupalith is made.
The junction of described housing and shielding cover is provided with the two seals device.
In bearing chamber, also be provided with the venting screw thread, be fixed with bleed screw on the screw thread.
The utility model has been set up housing between the rotor of motor and stator, and the intake tunnel of in the rotating shaft of rotor rotor, offering, when suction booster is worked, water in the pump housing can enter into from the water inlet of shielding cover in the housing, exhalant canal from rotor shaft flows to the impeller again, cooling effect to motor is very good, the utility model is provided with bearing chamber in the bottom of housing in addition, be provided with graphite bearing in the bearing chamber, because of the friction ractor between graphite and the pottery is littler, use the rotating shaft wearing and tearing littler, thereby noise is very little during suction booster work, the wearing and tearing of parts are also less, can increase the working life of parts.
Between housing and shielding cover, be provided with the two seals device, can guarantee that water can not enter the motor stator the inside and go, guarantee the safe and reliable operation of suction booster.
