Description
Technical Field
The utility model relates to the technical field of motor structural member sealing, in particular to a direct current and dry and wet dual-purpose floor washer fan sealing structure.
Background
The sealing reliability between the existing direct current and wet and dry fans and the structural members of the scrubber is extremely low, and gaps between the structural members are required to be filled by different methods so as to ensure the tightness of the motor; most enterprises choose to add rubber gaskets, gaskets or asbestos gaskets for foaming oil between structural members, or fill structural glue such as silica gel, epoxy glue and the like in gaps between the structural members to seal the motor after the structural glue is solidified; the seal between the few metal pieces may also be welded;
the existing motor sealing means are generally three kinds of the following: 1. when the rubber gasket, the gasket and the asbestos gasket for soaking oil are added, the cost is higher than that of other means, and the corresponding materials are selected by combining the running environment, the service life requirement and the installation size of the motor; the asbestos gasket also needs to be soaked in oil to ensure that sealing is formed during use, and the asbestos gasket is easy to break and inevitably loses during production. 2. The method has the advantages that compared with the method for placing the rubber ring, the method has low cost and convenient operation, and the sealing effect can be achieved after the parts are assembled and cured after the glue is coated on the joint surface; but most can spill over the motor surface and influence the motor outward appearance, still need the installer to clean, perhaps more serious can spill over to the part inside for the inside moving part of motor bonds, and the motor is unusual. 3. The method is suitable for sealing between two metal parts, but has hidden danger that the welding spot density is too small and can not be verified through visual detection, and the air tightness verification equipment has higher cost, so that the method is less used in small household appliances.
