毛(mao)病阐发:机器密封(feng)破坏;密封(feng)压(ya)盖未压(ya)平;拆卸地位错误(wu)。

处(chu)理方式(shi):改换机器密封(feng);调剂密封(feng)压(ya)盖;从(cong)头按(an)手(shou)艺请求拆卸。

05泵过热(re)

毛病阐发:泵(beng)螺(luo)杆(gan)与泵(beng)套共(gong)同太紧;机器密封回油孔梗塞;介(jie)子温(wen)渡过高。

处理(li)方式:查抄调(diao)剂泵螺杆与泵套空隙,须要(yao)的话,要(yao)改换部(bu)件;疏浚回(hui)油孔;采用须要(yao)的办法,下降介子温度(du)。

06泵振动大

毛病阐发:泵(beng)(beng)与电念头不齐(qi)心;泵(beng)(beng)内有氛(fen)围;螺杆与泵(beng)(beng)套不齐(qi)心或空隙大;装置高渡过(guo)高,泵(beng)(beng)内发生(sheng)气(qi)蚀(shi)。

处(chu)理方式:调(diao)剂(ji)地位,从头对中(zhong);查抄吸入管路,解除漏气部(bu)位;检(jian)验调(diao)剂(ji)或(huo)改换;下降装置(zhi)高度。

07运转超负(fu)荷

毛病阐发:介子黏(nian)渡过大;解除管路梗塞;螺杆与泵(beng)套发生严峻磨(mo)擦。

处理方式(shi):将介子恰当升温;停泵,疏(shu)浚排挤(ji)管路;检验或改换相干部件。
