Description

Sealing ring of dry-wet dual-purpose motor for dust collector

Technical Field

The utility model relates to a motor sealing technique field especially relates to a sealing washer of wet dual-purpose motor futilely for dust catcher.

Background

Along with the improvement of the living standard of people, the environmental protection consciousness and the energy consumption consciousness are deepened, the lithium battery technology is perfect, the existing brush series excitation motor for the household alternating current dust collector is gradually eliminated by the market due to the inherent defects of high power, high energy consumption, low service life, low efficiency, high noise and the like, the direct current brushless motor is used as a new product industry and is influenced by the imperfect technical structure, the power efficiency is low, the service life of the lithium battery is influenced, the environmental pollution is caused indirectly, the noise is greatly influenced by the imperfect technical structure, the body feeling comfort degree of people is influenced, and the imperfect technical structure also causes the direct current brushless motor for the existing dust collector to be obviously improved in the aspect of service life compared with the alternating current brush series excitation motor for the existing dust collector. Especially, the dry-wet dual-purpose brushless motor for the dry-wet dual-purpose dust collector, because the motor coil generates heat after being electrified in the operation of the motor, cooling airflow is needed to ventilate the motor coil, the dry-type motor drives the impeller to operate for the motor, negative pressure is formed in the fan cover to suck the airflow, so that the dust collector works, the airflow sucked in by the operation of the motor flows out through the motor winding part through the air duct, the airflow cools the motor winding when passing through the motor winding, but the dry-wet dual-purpose motor is a failure structure for avoiding that moisture contained in the sucked airflow enters the motor winding to cause corrosion short circuit of the motor winding, the principle is that a plurality of groups of fans/impellers are arranged on the dry-wet dual-purpose motor, the impeller is driven by the dry-wet dual-purpose motor to form negative pressure when the motor operates, the airflow is directly led out of the motor through the air duct without passing through the motor winding, in addition, the other end of the motor drives the cooling fan to operate, so that independent airflow is sucked into the motor to pass through the winding to cool the motor, the air current behind the cooling winding flows out of the motor after passing through the motor winding, the wet and dry dual-purpose motor of this scheme needs to make independent cooling air-out passageway on motor and dust catcher, very big waste wet and dry dual-purpose motor and wet and dry dual-purpose dust catcher volume, because wet and dry dual-purpose motor need increase the cooling fan in addition, the load power that the cooling fan caused has very big improvement dry wet and dry dual-purpose motor's loss is very big has reduced wet and dry dual-purpose motor efficiency, and the cooling fan is monolithic punching press formula structure, tear the damage and lead to wet and dry dual-purpose motor inefficacy damage under abominable operating mode condition very easily when the motor runs at a high speed, cause very big hidden danger to motor quality.
