一、如何查找离心式水泵的漏气部位 离心式水泵是依靠叶轮的高速旋转,在泵壳内形成低压区而抽水的,所以离心泵正常工作的关键条件之一是水泵和进水管不漏气,也不吸进空气。一旦空气进入水泵,不仅影响作业效率,而且水泵运行时振动厉害并产生噪音。 当水泵出水不足,或者启动后不出水时,应检查吸水管是否漏气,例如存在漏焊、裂缝、铸造砂眼或者结合处螺栓松动等缺陷。寻找水管漏气部位的方法是:找1根鸭毛(细纱条、薄纸片亦可),在水泵运行时凑近怀疑之处,观察羽毛的飘动情况。或者点燃一支香烟,观察烟气 First, how to find the leaking parts of centrifugal pumps Centrifugal pumps rely on high-speed rotation of the impeller, forming a low-pressure zone within the pump casing and pumping, so one of the key conditions for the normal operation of centrifugal pumps and water pipes airtight , Nor inhale the air. Once air enters the pump, it not only affects work efficiency, but also vibrates and generates noise when the pump is operating. When the pump is out of water, or start after the water, should check whether the suction pipe leaks, such as the existence of leak welding, cracks, casting trachoma or loose bolts and other defects. The way to find the place for water leaks is to find a duck feather (fine yarn, thin pieces of paper can also), in the pump running near suspicion, observe the feather of the fluttering situation. Or ignite a cigarette, observe the flue gas
