No line at inhalation of water can be filled automatically by pumping the water table known as the centrifugal self-priming pump. 不需在吸入管路內充滿(mǎn)水就能自動(dòng)地把水抽上來(lái)的離心泵稱(chēng)為自吸泵。
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. 水在葉輪高速轉動(dòng)的作用下與吸入管來(lái)的空氣相混合，形成氣水混合物排至分離室。
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. 隨后這種動(dòng)能便轉換成靜壓能，于是又加大了泵的吸入管與排出管間本來(lái)就很大的壓差。
