31、卧式泵叶轮口环间隙大小对能耗有什么影响? 答:卧式泵叶轮的口环是装在水泵叶轮正面(有的背面也装有口环)进口处,防止水泵内部漏水提高水泵效率的一个重要组成部件,口环内径与叶轮进口外径之间的间隙,称为口环的径向间隙,其值大小因口环内径的不同而不同,一般口环内径大、要求

31. What is the impact of the gap size of the horizontal pump impeller on energy consumption? A: The ring of the horizontal pump impeller is mounted on the front of the pump impeller (some of which is also equipped with a mouth ring) to prevent water leakage inside the pump. An important component of the pump efficiency is the gap between the inner diameter of the mouth ring and the outer diameter of the impeller inlet, which is called the radial clearance of the mouth ring. The value varies depending on the inner diameter of the mouth ring, and the inner diameter of the mouth ring is generally large.
