The tushen gine na tsaye bututun sinadarai famfo ne kunshe da sassa shida, su ne impeller, famfo jiki, famfo shaft, bearing, hatimi zobe, cikawa wasika.
1, impeller ne babban ɓangare na sinadarai famfo, shi juyawa gudun babban fitarwa karfi, impeller a kan impeller kuma taka muhimmiyar rawa, impeller kafin taro ya wuce matsayi daidaitaccen gwaji. A ciki da waje surface a kan impeller bukatar smoothness don rage hasarar gogewa na ruwa.
2, jikin famfo kuma aka kira famfo shell, shi ne babban jikin famfo. Yi aiki a matsayin goyon baya da kuma haɗi da rack da aka shigar da bearings.

3, rawar famfo shaft ne ta karɓi mai haɗi da injin lantarki, watsa nesa na injin lantarki zuwa impeller, don haka shi ne babban sashi na watsa makamashi na inji.
4, bearing ne kayan da aka sanya a kan famfo shaft don tallafawa famfo shaft, akwai jinguwa bearing da kuma motsawa bearing biyu. Rolling bearing amfani da man fetur a matsayin lubricant don ya dace gabaɗaya ne 2/3 ~ 3/4 da yawa zai zafi, da ƙananan kuma da sauti da kuma zafi! Ana amfani da bearings masu motsawa na man fetur mai haske a matsayin lubricant, don saka man fetur zuwa layin matakin man fetur. Man fetur da yawa dole ne ya fita a gefen shaft na famfo kuma ya shafi, ƙananan bearings dole ne su ƙone da zafi don haifar da hatsari! A lokacin da famfo aiki, bearing zafin jiki mafi girma a 85 digiri yawanci aiki a kusan 60 digiri, idan shi ne mafi girma don neman dalilin (ko akwai gurɓataccen abu, ko man fetur baƙar fata, ko ruwa) da kuma kula da shi a kan lokaci!
