2023-08-16

Lokacin shigar da mai tsabtace fitilar fitila, wajibi ne a yi amfani da samfurin da ya dace da mai tsabtace fitilar, in ba haka ba za'a iya samun ɓoyayyiyar ɓoyayyiyar ƙarancin ƙarancin dafa abinci da ƙarancin tsarkakewa. Daga murfin hayaki zuwa shaye-shaye, mafi kyawun tsarin shigarwa shine shigar da kayan aikin tsarkakewa da farko, sannan shigar da ma'aunin iska. Bayan an shigar da mai tsabtace hayaƙin mai, rarrabawa, tsaftacewa da haɗuwa da fan na centrifugal yakamata ya cika waɗannan buƙatu:

Da farko, tarwatsa mahalli da akwatin ɗaukar hoto kuma cire rotor don tsaftacewa, amma ba za a iya rarraba fan tare da watsa motar kai tsaye don tsaftacewa ba; Tsaftacewa da kuma duba tsarin daidaitawa, juyawarsa ya kamata ya zama mai sassauƙa. Bututun ruwa mai sanyaya ya kamata ya zama mai santsi kuma yakamata a yi gwajin matsa lamba akan tsarin duka, kuma gwajin gwajin kada ya zama ƙasa da 4 kg ƙarfi / cm 2 idan ba a ƙayyade takaddar fasaha na kayan aiki ba.

Na biyu, shigarwa na duka naúrar ya kamata a sanya shi kai tsaye a kan tushe tare da nau'i-nau'i na nau'i na nau'i na nau'i na ƙarfe. Wurin yankan da ke gindin rukunin da aka taru a filin ya kamata a kiyaye shi da kyau kuma kada a yi tsatsa ko sarrafa shi. Lokacin da aka sanya tushe a kan tushe, ya kamata a daidaita nau'i biyu na baƙin ƙarfe mai karkata. Wurin zama mai ɗaukar nauyi da tushe ya kamata a haɗa su tare, ƙarancin ƙarancin tsayi bai kamata ya wuce 0.2/1000 ba, auna shi tare da matakin akan sandal, ƙasa mara nauyi kada ta wuce 0.3/1000, auna tare da matakin a cikin a kwance tsakiyar jirgin saman wurin zama. Kafin scraping da bearing daji, da rotor axis line da gidaje axis line kamata a gyara da farko, da kuma yarda tsakanin impeller da iska ci tashar jiragen ruwa da yarda tsakanin sandal da raya gefen farantin na gidaje ya kamata a gyara don yin. ya dace da abubuwan da aka tanadar da takardun fasaha na kayan aiki.Don fan ɗin da aka taru tare da ƙuƙwalwar ƙuƙwalwa, nau'i-nau'i daban-daban na ramukan ramuka a kan nau'i-nau'i guda biyu na iya zama ƙarƙashin juyawa mai sauƙi bayan an shigar da rotor. Lokacin hada harsashi, ya kamata a yi amfani da layin axis na rotor azaman ma'anar gano wuri na harsashi, kuma axial da radial yarda tsakanin mashigar iska da mashigin harsashi ya kamata ya zama babban sauri zuwa kewayon da aka ƙayyade a cikin kayan aiki. takardun fasaha, yayin da ake duba ko an ƙarfafa kusoshi na anka. Idan ba a ƙayyade ƙimar izinin ba a cikin takaddun fasaha na kayan aiki, ƙaddamarwar axial gabaɗaya ya kamata ya zama 1/100 na diamita na waje na impeller, kuma ya kamata a rarraba izinin radial a ko'ina, kuma ƙimarsa ya zama 1.5/1000 ~ 3/ 1000 na diamita na waje na impeller (ƙananan diamita na waje shine ƙimar mafi girma). Lokacin daidaitawa, yi ƙoƙari don rage ƙimar rata don inganta ingantaccen aikin fan.Lokacin da fan na centrifugal ke yin lokaci, daban-daban coaxiality na fan shaft da kuma mota shaft: radial sakawa motsi kada ya wuce 0.05 mm, da karkatar ya kamata. bai wuce 0.2/1000 ba. Lokacin da ake hada igiya da harsashi mai ɗaukar nauyi, ya kamata a duba shi bisa ga takaddun fasaha na kayan aiki. Ya kamata a kiyaye tsangwama tsakanin murfin ɗaukar hoto da daji mai ɗaukar hoto ta 0.03 ~ 0.04 mm (aunawa diamita na waje na daji mai ɗaukar hoto da diamita na ciki na wurin zama).
