Imboni Yokukhiqiza Izimoto zikagesi, iqondisa ukukhiqizwa nokugqugquzelwa kwemishini yokonga amandla kagesi (imikhiqizo), ihlanganise umsebenzi wangempela wokonga ugesi nowokunciphisa ukungcola kwemboni yezokuxhumana, futhi inconywe, ukubuyekezwa kochwepheshe kanye nokwazisa umphakathi yiminyango enekhono. yezimboni kanye nobuchwepheshe bolwazi kanye nezimboni ezihlobene ezindaweni ezahlukene.Ikhathalogi ihlanganisa ingqikithi yamamodeli angama-344 ezigabeni eziyi-9.Phakathi kwabo, amamodeli we-transformer angu-96, ama-motor kagesi angu-59 amamodeli, ama-boilers angu-21 wezimboni, imishini yokushisela amamodeli angu-77, amamodeli angama-43 esiqandisini, amamodeli we-compressors angu-27 wemikhiqizo, umshini wepulasitiki onobuhle 5, amamodeli angu-13 fan, ukwelashwa kokushisa amamodeli amathathu.

Uhla lwemibhalo lusebenza iminyaka emithathu kusukela ngosuku olushicilelwe ngalo.Ngesikhathi sokuqinisekisa, uma kunokuqanjwa okusha kubuchwepheshe bomkhiqizo kanye noshintsho olukhulu kumazinga okuhlola, ibhizinisi lizophinde limemezele.^[2]

Izinyathelo zokuzivikela

Hlela Izwi

(1) Ngaphambi kokususwa, phephetha uthuli ebusweni benjini ngomoya ocindezelwe bese usula ukungcola okungaphezulu kuhlanzekile.

(2) Khetha indawo lapho injini ihlakazeka khona futhi uhlanze indawo yasensimini.

(3) Yazi izici zesakhiwo semoto kanye nezidingo zobuchwepheshe zokulungiswa.

(4) Lungiselela amathuluzi (kuhlanganise namathuluzi akhethekile) kanye nempahla edingekayo ukuze kuhlakazwe.

(5) Ukuze kuqondwe kabanzi amaphutha ekusebenzeni kwemoto, ukuhlolwa kokuhlola kungenziwa ngaphambi kokususwa lapho izimo zikhona.Kuze kube manje, injini izoba ukuhlolwa komthwalo, ukuhlolwa okuningiliziwe kwezingxenye zemoto zezinga lokushisa, umsindo, ukudlidliza nezinye izimo, kanye ne-voltage yokuhlola, yamanje, isivinini, njll. test, kukalwe ukulahlekelwa kwamanje okungenalutho nomthwalo ongenalutho, yenza irekhodi elihle.

(6) Nqamula ugesi, susa izintambo zangaphandle zenjini, futhi wenze irekhodi elihle.

(7) Hlola ukumelana nokufakwa kwezimoto ngemitha ye-meE enevoltheji efanele.Ukuze uqhathanise amanani okumelana nokufakwa kukalwa kusevisi yokugcina ukuze kutholwe izitayela zokufakwa kwezimoto kanye nesimo sokugquma, amanani okumelana nokufakwa kukalwa kumazinga okushisa ahlukene kufanele aguqulelwe kuzinga lokushisa elifanayo, ngokuvamile libe ngu-75degrees C.

(8) Isilinganiso sokuhlola sokumuncwa K. Uma isilinganiso sokumuncwa singaphezu kuka-1.33, ukushunqiswa kwemoto akumanzi noma akuswakama kakhulu.Ukuze kuqhathaniswe nedatha yangaphambilini, isilinganiso sokumuncwa esikalwa kunoma yiliphi izinga lokushisa siphinde siguqulelwe kuzinga lokushisa elifanayo.
