Uchungechunge lwe-JPCF yokuthinta okukodwa kwangaphakathi kokufakwa kwethumbu lomoya eliqondile kungama-couplings asheshayo wekhwalithi ephezulu. Yenziwe nge-nickel ehlanganiswe yonke into yethusi, enokumelana nokugqwala okuhle nokumelana nokugqoka, futhi ingasetshenziswa ezindaweni zokusebenza ezinokhahlo ezahlukahlukene.
Lesi sixhumi samukela idizayini yokuxhuma okukodwa, okwenza kube lula ukuxhuma ngokushesha nokunqamula amapayipi. I-threaded yayo yangaphakathi eqondile ngokuklama ivumela igesi ukuthi ihambe kahle ngokuhlanganyela, iqinisekisa ukudluliswa kwe-pneumatic okuphumelelayo. Iphinde ibe nokusebenza okuhle kokuvala, okungavimbela ngempumelelo ukuvuza kwegesi.
Izixhumi zochungechunge lwe-JPCF zisetshenziswa kakhulu ezinhlelweni zomoya, njengamathuluzi omoya acindezelwe kanye nemishini yomoya. Zingasetshenziswa emigqeni yokukhiqiza yezimboni, ukulungiswa kwezimoto, ukucutshungulwa kwemishini, neminye imikhakha. Lawa malungu alula ukufaka nokusebenza, okungathuthukisa kakhulu ukusebenza kahle komsebenzi.
