其水流回流時阻力很大，減漏效果好，但構(gòu)造復(fù)雜。減漏環(huán)的另一作用是準備用來承度的，因為，在實際運行中，在這個部位上，摩擦常是難免的，泵中有了減漏環(huán)，當間院磨大后，只須更換口環(huán)而不致使葉輪和泵殼報廢，因此，減漏環(huán)又稱承磨環(huán)、是一個易損件。

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
