就會(huì)產(chǎn)生垂直于軸方向的力——徑向推力。而且，由于泵在低效率下運(yùn)轉(zhuǎn)，使入口部位的液溫升高，蒸汽壓增高，容易出現(xiàn)汽蝕，為了預(yù)防發(fā)生汽蝕，應(yīng)設(shè)置泵在低流量下正常運(yùn)轉(zhuǎn)的小流量線。泵的保護(hù)管線——平衡線:對(duì)于輸送常溫下飽和蒸汽壓**大氣壓的液體處于泡點(diǎn)狀態(tài)的液體，為防止進(jìn)泵液體產(chǎn)生蒸汽或有氣泡進(jìn)入泵內(nèi)引起汽蝕，一般宜設(shè)平衡線。平衡線是由泵入口接至吸入罐(塔)的氣相段。泵的保護(hù)管線——預(yù)熱線:預(yù)熱線輸送介質(zhì)溫度大于200℃時(shí)，為避免切換泵時(shí)高溫液體急劇涌入待運(yùn)行的泵內(nèi).使泵體、葉輪受熱不均勻而損壞或變形，致使固定部分和旋轉(zhuǎn)部分出現(xiàn)卡住現(xiàn)象，因而需設(shè)預(yù)熱線，使停運(yùn)的泵保持待起動(dòng)狀態(tài)，以便隨時(shí)切換。泵的保護(hù)管線——旁通線:啟動(dòng)高揚(yáng)程泵時(shí)，出口閥單方面受壓過(guò)大，不易打開(kāi)，若強(qiáng)制開(kāi)啟，將有損壞閥桿、閥座的危險(xiǎn)。在出口閥前后設(shè)置帶有限流孔板的旁通線，便可容易開(kāi)啟。同時(shí)，旁通線還有減少管線振動(dòng)和噪聲的作用。</p><div
