When the water flows back, there is great resistance and good leakage reduction effect, but the structure is complex. Another function of the leakage reduction ring is to prepare it for bearing, because in actual operation, friction is often inevitable at this location. With the leakage reduction ring in the pump, when the wear is large, only the mouth ring needs to be replaced without causing the impeller and pump casing to be scrapped. Therefore, the leakage reduction ring, also known as the bearing ring, is a vulnerable part.渣漿泵雙環(huán)迷宮型的減漏環(huán)的作用
