例句
- No line at inhalation of water can be filled automatically by pumping the water table known as the centrifugal self-priming pump.不需在吸入管路内充满水就能自动地把水抽上来的离心泵称为自吸泵。
- Water at high-speed rotating impeller and the suction pipes under the gas mixture to form a gas-water mixture to the separation chamber row.水在叶轮高速转动的作用下与吸入管来的空气相混合，形成气水混合物排至分离室。
- Excessive speed of rotation of the impeller is liable to cause the pressure on the suction side to fall so low that the liquid will vaporize, thus causing damage to the impeller.随后这种动能便转换成静压能，于是又加大了泵的吸入管与排出管间本来就很大的压差。
