Daya gefen bakin karfe eccentric rage ne lebur. Wannan zane yana sauƙaƙe shaye-shaye ko magudanar ruwa kuma yana sauƙaƙe kulawa. Don haka, ana amfani da shi gabaɗaya don bututun ruwa a kwance.

Tsakiyar bakin karfe mai rahusa rahusa yana kan layi, wanda ke haifar da kwararar ruwa kuma yana da ƙarancin tsangwama tare da tsarin kwararar ruwan yayin rage diamita. Don haka, ana amfani da shi gabaɗaya don rage diamita na iskar gas ko bututun ruwa a tsaye.

3. Hanyoyin shigarwa daban-daban

Bakin karfe eccentric rage suna halin da sauki tsari, sauki masana'antu da amfani, kuma zai iya saduwa da iri-iri na haɗin bututun bukatun. Yanayin aikace-aikacen sa musamman sun haɗa da:

Haɗin bututun kwance: Tun da tsakiyar wuraren ƙarshen ƙarshen ƙarshen ƙarfe na bakin karfe ba a kan layin kwance ɗaya ba, ya dace da haɗin bututun kwance, musamman lokacin da bututun bututu ya buƙaci canza.

Mai shigar da famfo da shigar da bawul mai daidaitawa: Shigar saman lebur da shigarwa na ƙasa lebur na bakin karfe eccentric

Rarraba bakin karfe masu rarrafe suna da ƙarancin tsangwama ga kwararar ruwa kuma sun dace da rage diamita na iskar gas ko bututun ruwa a tsaye. Yanayin aikace-aikacen sa musamman sun haɗa da:

Haɗin bututun iskar gas ko a tsaye: Tunda tsakiyar ƙarshen biyu na bakin karfe mai raɗaɗi mai raɗaɗi yana kan axis guda ɗaya, ya dace da haɗin iskar gas ko bututun ruwa na tsaye, musamman inda ake buƙatar rage diamita.

Tabbatar da kwanciyar hankali na kwararar ruwa: Mai rage bakin karfe yana da ɗan tsangwama tare da tsarin kwararar ruwa yayin aikin rage diamita kuma yana iya tabbatar da daidaiton kwararar ruwan.

4. Zaɓin masu ragewa na eccentric da masu ragewa a cikin aikace-aikace masu amfani

A cikin ainihin aikace-aikacen, ya kamata a zaɓi masu rage masu dacewa bisa ga takamaiman yanayi da bukatun haɗin bututun. Idan kana buƙatar haɗa bututun kwance kuma canza diamita na bututu, zaɓi masu rage bakin karfe na eccentric; idan kana buƙatar haɗa iskar gas ko bututun ruwa na tsaye kuma canza diamita, zaɓi masu rage bakin ƙarfe na ƙarfe.
