渣漿泵的汽蝕與防止發(fā)生
渣漿泵汽蝕是泵中一種十分有害的現(xiàn)象。當(dāng)泵發(fā)生汽蝕時(shí)，會(huì)降低泵的各個(gè)性能，如泵的流量、揚(yáng)程、功率、效率等都會(huì)下降，并發(fā)生振動(dòng)、噪聲。泵如果長(zhǎng)期在汽蝕工況下運(yùn)轉(zhuǎn)，會(huì)發(fā)生流蝕破壞，當(dāng)汽蝕進(jìn)一步發(fā)展嚴(yán)重時(shí)，泵就會(huì)發(fā)生斷流而不能工作。所以必須避免泵在汽蝕工況下運(yùn)轉(zhuǎn)。渣漿泵
Cavitation and prevention of slurry pump
Cavitation is a very harmful phenomenon in slurry pump. When cavitation occurs in the pump, it will reduce the performance of the pump, such as the flow, head, power, efficiency, etc., and vibration and noise will occur. If the pump operates under the cavitation condition for a long time, it will be damaged by flow erosion. When the cavitation develops further, the pump will be cut off and cannot work. Therefore, it is necessary to avoid pump operation under cavitation condition. Slurry pump
