Abstract
The utility model discloses a canned electric submersible sewage pump, which is reliable in sewage. The canned electric submersible sewage pump comprises a motor and a water pump fixedly connected with each other, wherein the motor includes a stator and a rotor; bearing bases are respectively arranged on both ends of the rotor; a rolling bearing is correspondingly mounted in the bearing bases; therotor is supported by the roller bearing; a shielding can is arranged between the rotor and the stator and fixed on the bearing bases; and a mechanical sealing device is mounted on the output shaft end of the rotor butting against the rolling bearing. Due to the adoption of the shielding can and the rolling bearing, the canned electric submersible sewage pump can prevent the sewage from enteringthe motor, thereby enhancing the underwater operation safety of the electric submersible pump.
Description
Technical field
The utility model relates to a kind of sealing means of Submerged Motor Pumps, is used for the discharging of sewage, dirt.
Background technique
At present, well-known Submerged Motor Pumps is made of submersible motor and coaxial water pump.Because motor and pump are all worked under water, so the sealing part of motor is just very important.For the reliability that guarantees to seal, many submersible motors adopt shielding structure.But existing various shield electric machine all adopts sliding bearing, is lubricated with the medium of institute's pumping, can not be used for the emission treatment of sewage, dirt.And, promptly be used in the pumping cleaning fluid, once dehydrating operation (promptly doing running) takes place, sliding bearing and axle be quick-wearing very, therefore makes, maintenance cost is higher.
The model utility content
Technical problem to be solved in the utility model provides the latent dirty electric pump of a kind of shielding, with reliability, the reduction manufacture cost that improves shield electric machine work.
The technological scheme that its technical problem that solves the utility model adopts is: the latent dirty electric pump of this shielding comprises motor and the water pump 13 that is fixedly connected, described motor comprises motor stator 4 and rotor 6, wherein, the two ends of described rotor 6 are respectively equipped with bearing support 2 and bearing support 9, rolling bearing 1 and rolling bearing 7 correspondingly are installed in described bearing support 2 and the bearing support 9, described rotor 6 is by rolling bearing 1 and rolling bearing 7 supportings, between described motor stator 4 and rotor 6, be provided with housing 5, described housing 5 is fixed on described bearing support 2 and the bearing support 9, and the axle head that goes out of described rotor 6 is equipped with mechanical seal device 10 in the position that nestles up rolling bearing 7.
Further, described housing 5 is fixed on the described bearing support 2,9 in the fixing mode of socket joint, between described housing 5 and described bearing support 2 and bearing support 9 seal ring 3 and seal ring 8 are installed correspondingly, the periphery of described housing 5 is fixing with chuck 11 and chuck 12.
Further, described housing 5 bonds together mutually with described bearing support 2 and bearing support 9.
Compared with prior art, the beneficial effects of the utility model are: the various mechanical seals that (1) submersible motor of the prior art adopts are a kind of motive sealings, in use all there is a certain amount of leakage, and motor stator of the present utility model is because there is the static seal of housing to exist, therefore can not cause water inlet, increase the submersible motor reliability; (2) rolling bearing of shield electric machine of the present utility model does not directly contact with sewage when the work operation because of being furnished with mechanical seal, even micro-leakage is arranged, the lubricant grease that carries can keep working lubrication, does not do running so be afraid of, and can not damage motor; (3) housing of shield electric machine of the present utility model adopts detachable connection, and is cheap for manufacturing cost, uses installation and maintenance easy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an an embodiment's of the present utility model sectional drawing.
Embodiment
As shown in Figure 1, shielding sewage dirt Submerged Motor Pumps of the present utility model comprises motor and the water pump 13 that is fixedly connected, wherein, motor comprises motor stator 4 and rotor 6, the two ends of rotor 6 are respectively equipped with bearing support 2 and bearing support 9, rolling bearing 1 and rolling bearing 7 correspondingly are installed in bearing support 2 and the bearing support 9, the two ends of rotor 6 are respectively by rolling bearing 1 and rolling bearing 7 supportings, be provided with housing 5 between motor stator 4 and rotor 6, this housing 5 is close to the inwall of motor stator 4.And the two ends of housing 5 are separately fixed on bearing support 2 and the bearing support 9.If housing 5 is fixed on described bearing support 2 and the bearing support 9 in the fixing mode of socket joint, then make and that housing 5 is installed is easier, also be more convenient for motor is maintained.For strengthening the reliability of sealing, can also between housing 5 and bearing support 2 and bearing support 9, seal ring 3 and seal ring 8 be installed correspondingly, and the periphery at housing 5 is fixing with chuck 11 and chuck 12, make the static sealing that housing 5 in the motor stator 4 and seal ring 3, seal ring 8 and bearing support 2, bearing support 9 constitute rotor 6, to prevent because of the infringement of the leakage fluid of axle envelope to motor stator.In addition, housing 5 and bearing support 2 and bearing support 9 can also be bonded together mutually, with the reliability of further enhancing sealing.The axle head that goes out of rotor 6 is equipped with mechanical seal device 10 in the position that nestles up rolling bearing 7, and this mechanical seal device 10 can be general on the market mechanical seal device, and it connects mutually with rotor 6 and bearing support 9.Bearing support 9 has the sealing grease chamber, and mechanical seal device 10 is placed in the grease chamber that axle head of rotor 6.
