Isicupho Se-Bellows
Iyunithi eyinhloko yokusebenza ye-bellows, egcwele uketshezi olunezinga lokushisa lokuhwamuka eliphansi kunezinga lokushisa lokugcwala kwamanzi. Lapho umshini usanda ukuqala, kuvela amanzi ajulile anezinga lokushisa eliphansi emapayipini futhi uketshezi oluse-bellows lusesimweni sokujiya. I-trap iyavulwa. Lapho izinga lokushisa lamanzi ajulile likhuphuka kancane, uketshezi oluse-bellows luqala ukuhwamuka futhi ingcindezi ngaphakathi kuyanda. Ngenxa yalokho, i-film ihambisa i-valve core ibheke ohlangothini lokuvala. Ngaphambi kokuthi amanzi ajulile afinyelele ezingeni lokushisa lokugcwala, i-trap ivalwa ngokuphelele. I-bellows ilawula ukuvula nokuvala kwama-valve ngokushintsha kwezinga lokushisa lesitimu ukuze imelane nesitimu futhi ikhiphe amanzi. Kukhona ama-bellows amabili akhethwayo anezinga lokushisa lokuvula eliphansi ngo-15°C noma 30°C kunezinga lokushisa lokugcwala.

Kukhona ukujiya okushisayo okuphezulu phambi kwe-Bellows Trap (uhlobo lokulinganisa umfutho we-steam) lapho isebenza, futhi akukho ukuvuza komhwamuko, ngakho-ke umphumela wokonga amandla ubalulekile.

I-Bellows trap, phakathi kwayo yonke imibhobho ye-steam ekhona, okwamanje iyisikhundla esifanele se-low-pressure (ngomfutho ongaphansi kuka-PN25) hot motive (disc) traps noma ama-bimetallic elements traps (ngomfutho ongaphansi kuka-PN16).

1.Ijubane elisheshayo lokusebenza nokungavuzi.
2.Isakhiwo esilula nokulungiswa okulula.
3.Zonke izingxenye zenziwe ngensimbi engagqwali enziwe nge-alloy, imelana nokugqoka, ukugqwala kwegesi, ukuqina isikhathi eside.
4.Ikhono lokukhipha okuhle ngokukhishwa okusheshayo nokufakwa okulula.
5.Iyakwazi ukuhlanganisa ama-bellows amaningi, ifanele ukukhishwa okukhulu.
6.Amakhono amahle okukhipha umoya, anokumelana namakhaza, ukungavuzi, nokucindezela emuva okungu-75%.
