Muri sisitemu ya feri ya pneuamtic, umwuka wafunzwe ni uburyo bukoreshwa bukoreshwa mukugumya umuvuduko uhoraho kandi ukareba ko umwuka usukuye bihagije kugirango imikorere isanzwe ya valve muri sisitemu.Ibintu bibiri bigize molekile ya sikeri yumye hamwe nubushakashatsi bwumuvuduko wumwuka byashizweho kugirango bitange umwuka usukuye kandi wumye kuri sisitemu yo gufata feri no gukomeza umuvuduko wa sisitemu muburyo busanzwe (mubisanzwe kuri 8 ~ 10bar).
Muri sisitemu ya feri yimodoka, compressor de air isohora umwuka urimo umwanda nkumwuka wamazi, iyo itavuwe, ishobora guhinduka mumazi yamazi hanyuma igahuzwa nindi myanda itera ruswa, ndetse igahagarika trachea mubushyuhe bukabije, bigatuma valve itakaza efficacy.
Imashini yumwuka yimodoka ikoreshwa mugukuraho amazi, ibitonyanga byamavuta nibindi byanduye mumuyaga wafunzwe, bishyirwaho nyuma ya compressor de air, mbere ya valve irinda imirongo ine.Kandi ikoreshwa mugukonjesha, kuyungurura no gukama umwuka wafunzwe, nanone irashobora gukuraho imyuka yamazi, amavuta, umukungugu nibindi byanduye, bitanga umwuka wumye kandi usukuye kuri sisitemu yo gufata feri.
Imashini yumwuka wumuyaga nicyuma gishya cyumubyimba hamwe na sikeli ya molekile nkicyuma cyayo.JZ-404B icyuma cya molekuline nigicuruzwa cyogukora hamwe ningaruka zikomeye za adsorption kuri molekile zamazi.Ibice byingenzi bigize ni microporome yuburyo bwa alkali icyuma cya aluminium silikatike hamwe nu mwobo mwinshi kandi mwiza.Amazi ya molekile cyangwa andi marekile byerekanwa hejuru yimbere binyuze mu mwobo, hamwe ninshingano yo gushungura molekile.Amashanyarazi ya molekuline afite igipimo kinini cya adsorption kandi iracyafite molekile zamazi neza mubushyuhe bwo hejuru bwa 230 ℃.
Ubushuhe buri muri sisitemu buzonona umuyoboro kandi bugire ingaruka kuri feri, ndetse birashobora no kunanirwa na sisitemu yo gufata feri.Kubwibyo, hagomba kwitonderwa gusohora amazi kenshi muri sisitemu no gusimbuza buri gihe icyuma cyumisha.
