h.機(jī)械容差——即使單個(gè)部件的容差值在生產(chǎn)商規(guī)范所規(guī)定的范圍內(nèi)，機(jī)械容差仍可引起機(jī)械內(nèi)的振動(dòng)。簡(jiǎn)言之，泵組裝的零件越多，(在其他條件相同的情況下)容差"累計(jì)"使機(jī)械產(chǎn)生振動(dòng)的風(fēng)險(xiǎn)越大。單個(gè)部件在檢查時(shí)可能在規(guī)范(通常為ASME/)允許的范圍內(nèi)。由于這樣一個(gè)事實(shí)的存在，即采用可能產(chǎn)生問(wèn)題的已加工部件查找并確定其他可能問(wèn)題，上述情況將變得更為復(fù)雜。精確度和垂直狀態(tài)的檢查將難于在實(shí)地準(zhǔn)確測(cè)量，但是這是確定問(wèn)題的途徑。i.在另一方面，如果容差直接涉及轉(zhuǎn)動(dòng)部件，則機(jī)械容差引起的振動(dòng)將易于診斷。"失圓"或"失方"的加工部件可能導(dǎo)致在其他部件內(nèi)出現(xiàn)束縛或磨削。參考下文"外部原因?qū)е抡駝?dòng)"中的內(nèi)容，區(qū)別機(jī)械容差與管道校準(zhǔn)問(wèn)題。j.機(jī)械松動(dòng)——為了便于討論，本文中的機(jī)械松動(dòng)*指螺母和螺栓沒(méi)有恰當(dāng)進(jìn)行緊固的情況。單獨(dú)的螺帽在裝配時(shí)可能沒(méi)有緊固或在運(yùn)輸和安裝過(guò)程中出現(xiàn)松動(dòng)。所有外部螺帽在運(yùn)輸和安裝時(shí)應(yīng)解開(kāi)。生產(chǎn)商每次就裝配提出建議時(shí)，所有外部螺帽應(yīng)緊固并在隨后進(jìn)行定期緊固(對(duì)于大多數(shù)機(jī)械，建議每年緊固一次)。內(nèi)部原因引起的振動(dòng)為了便于進(jìn)行論述，本文中"內(nèi)部原因"指機(jī)器內(nèi)部的原因，不論是在泵的外部或內(nèi)部。山東耐堿離心泵流量江蘇地區(qū)銷售離心泵——靖江市瑞鑫泵業(yè)有限公司。</p><div
