把動(dòng)環(huán)壓向彈簧能自由地彈回來）。（2）密封面潤滑油量不足引起干摩擦或拉毛密封端面。對(duì)策：油室腔內(nèi)潤滑油面高度應(yīng)加到高于動(dòng)、靜環(huán)密封面。（3）轉(zhuǎn)子周期性振動(dòng)。原因是定子與上、下端蓋未對(duì)中或葉輪和主軸不平衡，汽蝕或軸承損壞（磨損），這種情況會(huì)縮短密封壽命和產(chǎn)生滲漏。對(duì)策：可根據(jù)維修標(biāo)準(zhǔn)來糾正上述問題。2、由于壓力產(chǎn)生的滲漏（1）高壓和壓力波造成的機(jī)械密封滲漏由于彈簧比壓力及總比壓設(shè)計(jì)過大和密封腔內(nèi)壓力超過3MPa時(shí)，會(huì)使密封端面比壓過大，液膜難以形成，密封端面磨損嚴(yán)重，發(fā)熱量增多，造成密封面熱變形。對(duì)策：在裝配機(jī)封時(shí)，彈簧壓縮量一定要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象，高壓條件下的機(jī)械密封應(yīng)采取措施。為使端面受力合理，盡量減小變形，可采用硬質(zhì)合金、陶瓷等耐壓強(qiáng)度高的材料，并加強(qiáng)冷卻的潤滑措施。（2）真空狀態(tài)運(yùn)行造成的機(jī)械密封滲漏泵在起動(dòng)、停機(jī)過程中，由于泵進(jìn)口堵塞，抽送介質(zhì)中含有氣體等原因，有可能使密封腔出現(xiàn)負(fù)壓，密封腔內(nèi)若是負(fù)壓，會(huì)引起密封端面干摩擦，內(nèi)裝式機(jī)械密封會(huì)產(chǎn)生漏氣（水）現(xiàn)象，真空密封與正壓密封的不同點(diǎn)在于密封對(duì)象的方向性差異，而且機(jī)械密封也有其某一方向的適應(yīng)性。蘇州泵用機(jī)械密封件件</p><p
