Ungayikhetha kanjani ukuncipha kwengcindezi yegesi?

Ukukhetha umfutho wegesi we-gesi kudinga ukubheka izici eziningana, sifingqa lezi zinto ezinhlanu ezilandelayo.

Ⅰ.Uhlobo lwegesi

1. I-Complosive Amagesi

Uma umoya-mpilo, i-argen namanye amagesi angewona awonakele, ngokujwayelekile ungawukhetha ithusi elijwayelekile noma unciphise ingcindezi yengcindezi yensimbi. Kepha kumagesi awonakalisayo afana ne-hydrogen sulfide, chlorine namanye amagesi awonakele, kufanele ukhethe izinto zokulwa nokuphikiswa ezenziwe ngengcindezi ukunciphisa ukuncipha, ukuze kuvikeleke ukuncishiswa kwengcindezi ekucindezelweni futhi kulimele, ukuqinisekisa ukuphepha nokusetshenziswa okujwayelekile.

2. Amagesi ahlangene

Amagesi avuthayo anjenge-hydrogen, acetylene, njll., Khetha ukuncipha kwengcindezi enzelwe ngokukhethekile amagesi avuthayo. Lokhu kunciphiswa kwengcindezi kuvame ukuba nesakhiwo esikhethekile sokubopha kanye nezindlela zokufakazelwa kwe-proof, njengokusetshenziswa kokwakheka kwamafutha angenayo uwoyela, ukugwema oxhumana naye wokuthambisa kawoyela namagesi ahlanganayo abangelwa umlilo noma izingozi zokuqhuma.

Ⅱ.Ukufaka nokukhishwa kwezingcindezi

1.Uhla lokucindezela lokufaka

Uhla lwengcindezi lomthombo wegesi ludinga ukucaciswa. Ingcindezi yokufaka ephezulu yengcindezi yokunciphisa umfutho kumele ikwazi ukufeza isidingo esikhulu sengcindezelo yomthombo wegesi. Isibonelo, uma ingcindezi ephezulu ye-yslinder yegesi iyi-15mpa, bese kuba nengcindezi ephezulu yokufaka yengcindezi ekhethiwe yokunciphisa umfutho kufanele ingabi ngaphansi kwe-15mpa, futhi kunconywe ukuthi kudonswe ingcindezi yokucindezela okuphezulu kwe-10% - 20% ephakeme kunokucindezela okuphezulu komthombo wegesi.

2. Ukuphuma kwengcindezi kububanzi

Nquma ububanzi bengcindezi bokukhipha ngokuya ngezidingo zemishini yangempela. Imishini ehlukene inezidingo ezihlukile zokucindezela kukagesi, okufana ne-laboratory gas chromatograph kungadinga ingcindezi eqinile kagesi engu-0.2 - 0.4MPA, imishini yokufaka i-welding ingadinga u-0.3 - 0.7mpa acetylene noma ingcindezi yomoya-mpilo. Ukukhetha uhla lwezingcindezi zokukhipha kungamboza imishini edingekayo ukuncipha kwengcindezi, futhi kungashintsha ngokunembile ingcindezi yokuphuma ukuze ihlangabezane nezidingo zokulawula izingcindezi zemishini.

Ⅲ.Izidingo Zokugeleza

1. Izidingo zokugeleza kwemishini

Qonda izidingo zokugeleza kwemishini usebenzisa igesi. Isibonelo, imishini enkulu yokusika yezimboni idinga i-oksijini enkulu kanye negesi, izinga lokugeleza kwalo lingafinyelela inqwaba yamamitha ayi-cubic ngehora, kuyadingeka ukukhetha ingcindezi yokucindezela okuphezulu ukuze uhlangabezane nezidingo zegesi zomshini. Ngezinsimbi ezincane zelebhu, isidingo sokugeleza singaba amalitha ambalwa kuphela ngomzuzu, futhi ngenxa yalokho ukunciphisa ukugeleza okuncane okuncane kungakhethwa.

2. Ingcindezi yokunciphisa ukugeleza kwamapharamitha

Hlola amapharamitha wokugeleza we-Pressure Recer, evame ukuvezwa ngokuya ngokugeleza okuphezulu kokuphuma ngokucindezela okuthile kokufaka. Lapho ukhetha, qiniseka ukuthi isilinganiso sokuphuma esiphezulu sengcindezelo yokunciphisa ingcindezi singahlangabezana nokufunwa okuphezulu kwemishini nokuthi ukunciphisa ukucindezela kungagcina ingcindezi yokuphuma okusebenzayo kwemishini.

Ⅳ.Izidingo Zokunemba

1. Ukunemba Ukuqinisekiswa Kwengcindezelo

Kwabanye izidingo zokunemba zokucindezela kwemishini ephezulu yokunemba, njengokuhlaziywa kwensimbi yokunemba, ukukhiqizwa kwe-chip ye-elekthronikhi neminye imikhakha yemishini, kudingeka ukhethe umsebenzi wokuhlola oqondile wokucindezela. Lezi zincindezi zokucindezela zivame ukusebenzisa izingcindezi eziphezulu zokulawula izingcindezi kanye nama-gauges abucayi ama-gauges, angalawula ukuguquguquka kwengcindezi yokukhipha ngaphakathi kwebanga elincane kakhulu, njenge- ± 0.01MPA.

2. Ukunemba kwe-Gauge

Ukunemba kwegeji yengcindezi ekunciphiseni kwengcindezi nakho kubalulekile. Igeyimu yokunemba ephezulu ingabonisa i-Pressure Value ngokunembe kakhudlwana, okulungele umsebenzisi ukuguqula nokubheka ingcindezi ngokunemba. Ukunemba kwama-Gares Gauges ekucindezelweni kwengcindezi kokusetshenziswa kwezimboni ezijwayelekile kungaba ± 2.5%, kanti izicelo ezidinga ukunemba okuphezulu, ukunemba kwama-gressges ama-gauges angadinga ukuba yi- ± 1% noma ngaphezulu.

Ⅴ.Ukusebenza Kwezokuphepha

1. Ukulungiswa kwe-valve yephepha

Ukuncipha kwengcindezi kufanele kufakwe i-valve esebenzayo yokuphepha. Lapho ingcindezi yemiphumela idlula ingcindezi yokuphepha ebekiwe, i-valve yokuphepha ingavula ngokuzenzakalela ukukhulula igesi, ivikele ingcindezi ekubeni phezulu kakhulu ukubangela ukulimala kwemishini emihle noma kubangele izingozi zokuphepha. Ingcindezi yokuvula ye-valve yezokuphepha kufanele iguqulwe futhi ngeke ingasebenzi kahle ngaphakathi kwebanga elijwayelekile lokucindezela.

2. Ezinye izindlela zokuphepha

Abanye ukuncipha kwengcindezi kuhlotshiswe ngezinto zokuphepha ezifana nokuvikelwa okungaphezulu kwe-anti-flameback (ngamagesi avuthayo). Okwehliswa kwengcindezi esetshenziswe ezindaweni ezikhethekile, njengokushisa okuphezulu, umswakama noma izimo eziyingozi zokuqhuma, kuyadingeka ukubheka izinga lokuvikela legobolondo layo (njengokulinganisa kwe-IP) ukuqiniseka ukuthi ukuncipha kwengcindezi kungasebenza ngokuphephile nangokwethembekile.
