1results about How to "Improve sand control effect" patented technology

This utility model relates to the field of water pump equipment technology, specifically to a submersible motor for wells with enhanced sand-proof performance. It includes a cover plate, a motor mount, and a sand-proof device. The sand-proof device includes a sand-proof seat, a sand-throwing sleeve, wear-resistant components, and auxiliary components. The sand-proof seat is positioned between the cover plate and the motor mount. The sand-throwing sleeve is fixedly connected to the sand-proof seat. The wear-resistant components are respectively positioned on the sand-proof seat and the motor mount. By setting the sand-proof seat between the cover plate and the motor mount, and setting the sand-throwing sleeve and wear-resistant components on the sand-proof seat, the sand-proof seat has better wear resistance. When the wear resistance of the sand-proof seat is enhanced, the gap between the sand-throwing sleeve and the sand-proof seat can be maintained for a long time, preventing sand and other impurities from entering the motor mount through the gap between the sand-proof seat and the sand-throwing sleeve. Therefore, the service life of the sand-proof seat is improved, thereby improving the sand-proof performance and service life between the motor mount and the cover plate, and preventing water ingress and damage to the motor.
