Rarraba Piston:
Tun da pistons na ciki konewa injuna aiki a karkashin high zafin jiki, high matsa lamba da kuma high load yanayi, da bukatun ga pistons ne in mun gwada da high, don haka muka yafi magana game da rarrabuwa na ciki konewa pistons.
1. Dangane da man da ake amfani da shi, ana iya raba shi zuwa pistons injunan mai, da injin dizal, da piston gas.
2. Dangane da kayan aikin fistan, ana iya raba shi zuwa simintin ƙarfe na ƙarfe, fistan ƙarfe, fistan alloy na aluminum da piston haɗaka.
3. Dangane da tsarin kera fistan blank, ana iya raba shi zuwa fistan simintin nauyi, fistan simintin matsi da fistan ƙirƙira.
4. Dangane da yanayin aiki na piston, ana iya raba shi zuwa nau'i biyu: piston da ba a matsawa ba da piston da aka matsa.
5. Dangane da amfani da fistan, ana iya raba shi zuwa pistons na mota, pistons na manyan motoci, pistons babur, pistons na ruwa, pistons na tanki, pistons na tarakta, pistons na lawnmower, da sauransu.
Bukatun Fasaha:
1. Dole ne a sami isasshen ƙarfi, ƙwanƙwasa, ƙaramin taro da nauyi mai sauƙi don tabbatar da ƙaramin ƙarfi mara ƙarfi.
2. Kyakkyawan halayen thermal, babban juriya na zafin jiki, matsa lamba mai girma, juriya na lalata, isasshen ƙarfin zafi, da ƙananan yanki na dumama.
3. Ya kamata a sami ɗan ƙaramin juzu'i tsakanin fistan da bangon fistan.
4. Lokacin da yawan zafin jiki ya canza, girman da girman siffar ya kamata ya zama ƙananan, kuma ya kamata a kiyaye ƙananan rata tare da bangon Silinda.
5. Ƙimar haɓakar haɓakar thermal ƙananan ƙananan, ƙayyadaddun nauyin ƙananan ƙananan ƙananan ƙananan, kuma yana da kyakkyawan raguwa da ƙarfin zafi.
Yanayin aiki:
Piston yana aiki a ƙarƙashin yanayin zafi mai zafi, babban matsin lamba, babban sauri da lubrication mara kyau.Piston yana cikin hulɗa kai tsaye tare da iskar gas mai zafi, kuma zafin jiki na nan take zai iya kaiwa fiye da 2500K.Sabili da haka, dumama yana da tsanani kuma yanayin zafi yana da kyau sosai, don haka yawan zafin jiki na piston yana da yawa yayin aiki, saman ya kai 600-700K, kuma yawan zafin jiki yana da rashin daidaituwa;saman fistan yana fuskantar matsin lamba na iskar gas yana da girma sosai, musamman matsin bugun jini na aiki shine mafi girma, injin mai ya kai 3-5MPa, injin dizal kuma ya kai 6-9MPa, wanda hakan ya sa piston yana haifar da tasiri kuma yana ɗaukar tasirin matsa lamba;~ 12m / s) motsi mai maimaitawa, kuma saurin yana canzawa akai-akai, wanda ke haifar da babban ƙarfin da ba zai iya aiki ba, wanda ya sa piston ya zama babban ƙarin kaya.Lokacin da piston ya yi aiki a ƙarƙashin irin wannan yanayi mai tsanani, zai zama lalacewa da kuma hanzarta lalacewa, kuma zai haifar da ƙarin kaya da damuwa na zafi, kuma a lokaci guda, gas zai lalata shi da sinadarai.
Binciken fistan galibi shine auna diamita na siket, tsayin zobe na piston da girman ramin kujerar piston:
①Ya kamata a ƙayyade zaɓi na piston bisa ga girman gyaran silinda.Yawancin lokaci, girman girman girman yana alama akan saman fistan;
②A cikin jerin masu ciyar da kifi iri ɗaya, tsarin pistons ba lallai bane iri ɗaya bane.Don haka, lokacin siyan pistons, dole ne a zaɓi nau'ikan pistons daidai da nau'in injin.A kan injin guda ɗaya, iri ɗaya, rukuni ɗaya ko Pistons tare da lambar samfurin iri ɗaya;wannan ƙirar dole ne ta yi amfani da pistons tare da lambar samfurin iri ɗaya don tabbatar da cewa bambancin diamita da ingancin piston bai wuce kewayon da masana'anta na asali suka kayyade ba.In ba haka ba, zai sa injin ya ƙone sosai, ya yi aiki mai tsanani, kuma ya rage tattalin arziki da wutar lantarki..Don haka, lokacin zabar pistons, dole ne a zaɓi nau'in piston daidai gwargwadon nau'in injin.
