Aisiphethu segesi, eyaziwa nangokuthi i-gas strut noma i-gas lift, iyisakhi somshini esisebenzisa igesi ecindezelwe ukuhlinzeka ngokusekelwa nokulawula ukunyakaza ezinhlotsheni ezahlukene zokusebenza. Umehluko omkhulu phakathi kwentwasahlobo yegesi evamile (ejwayelekile) kanye nentwasahlobo yegesi kagesi usekutheni ezikhiqiza futhi zilawule amandla azo.
1. Intwasahlobo Yegesi Ejwayelekile:
- Indlela:Iziphethu zegesi ezivamilezisebenza ngokusekelwe ezimisweni ezibonakalayo zokucindezela igesi. Zakhiwe isilinda esigcwele igesi ecindezelwe (ngokuvamile i-nitrogen) kanye ne-piston ehamba ngaphakathi kwesilinda. Ukunyakaza kwe-piston kukhiqiza amandla angasetshenziswa ukusekela noma ukuhambisa imithwalo.
- Ukulawula: Amandla asetshenziswa yintwasahlobo ejwayelekile yegesi ngokuvamile ahlala eqinile futhi ancike kugesi ecindezelwe ngaphambilini ngaphakathi kwesilinda. Amandla awakwazi ukulungiswa kalula ngaphandle kokuthi intwasahlobo yegesi ishintshwe noma ilungiswe ngesandla ngesikhathi senqubo yokukhiqiza.
2. Intwasahlobo Yegesi Kagesi:
- Indlela:Imithombo kagesi kagesiNgakolunye uhlangothi, faka injini kagesi noma i-actuator ngaphezu kwesilinda esigcwele igesi. Injini kagesi ivumela ukulawula okunamandla nokunembile kwamandla asetshenziswa yintwasahlobo yegesi.
- Ukulawula: Inzuzo eyinhloko yeziphethu zikagesi zikagesi ukuthi zinikeza amazinga amandla angahlelwa futhi alungisekayo. Lokhu kulungiswa kuvame ukufezwa ngokulawula imoto kagesi, okuvumela ukulungiswa kwesikhathi sangempela emandleni asetshenziswa yiphethu. Leli zinga lokulawula liwusizo ikakhulukazi ezisetshenzisweni lapho kudingeka khona amandla aguquguqukayo noma lapho kungadingeka khona ukulungiswa ngokushesha.
Ngamafuphi, umehluko omkhulu usekusetshenzisweni kokulawula. Iziphethu zegesi ezivamile zithembele ekucindezelweni ngokomzimba kwegesi ukuze kube namandla, futhi amandla azo ngokuvamile azinzile. Iziphethu zegesi kagesi zihlanganisa injini kagesi yokulawula amandla aguqukayo nahlelekile, okuhlinzeka ngokuguquguquka okukhulu kanye nokuzivumelanisa nezimo ezinhlelweni ezahlukahlukene. Ukukhetha phakathi kwazo kuncike ezidingweni ezithile zesicelo kanye nezinga lokulawula kanye nokulungiswa okudingekayo.
