Bayan da aka tattara compressor, ya zama dole don duba gaba ɗaya coaxial na taron.Idan coaxiality ya fita daga juriya, zai haifar da karce tsakanin sassa ko kuma rotor ya makale.
4. Haɗari da gano lalacewar rotor
Yayin aiki na yau da kullun na injin damfara, idan sautin da ba na al'ada ba, ƙarar rawar jiki, zazzabi mai tsayi na dogon lokaci, ko kuma abin hawa na yanzu yana faruwa, dole ne a rufe shi don dubawa da kyau.Ya kamata ku mai da hankali kan bincika ko damfaran iska sun lalace kuma ko ƙarshen ramin rotor ya lalace.Idan za'a iya gano lalacewar na'urar ta rotor a cikin lokaci kuma na'urar ta mutu nan da nan, ba zai haifar da zafi ba kuma ya makale, kuma ba zai haifar da lalacewa ga manyan kayan aikin injiniya ba.Idan ba'a gano lalacewar ƙarshen rotor a cikin lokaci ba kuma ana sarrafa na'urar kwampreshin iska na dogon lokaci, juzu'i da zamewa tsakanin da'irar ciki na ɗaukar hoto da matsayi na shigarwa na rotor gaba ɗaya zai faru.A cikin lokuta masu tsanani, matsayi mai ɗaukar rotor zai zama shuɗi, mai laushi da bakin ciki, ko kuma ƙarshen rotor ya bayyana.Da'irar ciki na ɗaukar murfin yana makale, yana haifar da da'irar waje ta jujjuya, yana haifar da rami mai ɗaukar murfin ƙarshen ya girma ko kuma daga zagaye.Yana iya ma ya faru cewa lalacewa ta hanyar kai tsaye yana haifar da rotor don lalacewa a ƙarƙashin aikin babban iko, yana lalata rotor coaxiality.
Duban rotors yin da yang gabaɗaya ya dogara da lalacewa da karce na rotor.Gilashin saƙar sa ba zai zama ƙasa da 0.5mm-0.7mm na diamita mara kyau ba.Yankin karce bazai zama mafi girma fiye da 25mm2 ba, zurfin ba zai zama mafi girma fiye da 1.5mm ba, kuma rashin axiality na ƙarshen rotor shaft ba zai zama mafi girma fiye da 0.010mm ba.
