Isimo lapho isikulufu singakwazi ukukhishwa futhi singakwazi ukususwa sibizwa ngokuthi "ukukhiya" noma "ukuluma", okuvame ukwenzeka kuzibophelelo ezenziwe ngensimbi engagqwali, i-aluminium alloy, i-titanium alloy nezinye izinto. Phakathi kwazo, izixhumi ze-flange (njengamaphampu nama-valve, imishini yokunyathelisa nokudaya), udonga lwesitimela nodonga lwamakhethini izinga lokuqala lokukhiya izinga eliphezulu, kanye nezicelo zokukhiya amathuluzi kagesi yizindawo ezisengozini enkulu yokukhiya izinsimbi zensimbi ezingenasici.
Le nkinga ibilokhu ikhathaza imboni yokubopha insimbi engagqwali isikhathi eside. Ukuze kuxazululwe le nkinga, ochwepheshe bezimboni ze-fastener baye bazama konke okusemandleni abo ukuqala kusukela emthonjeni, kuhlanganiswe nezici zezinsimbi zensimbi engagqwali, futhi bafingqa uchungechunge lwezinyathelo zokuvimbela.
Ukuze uxazulule inkinga ye-"lock-in", kuyadingeka ukuthi uqale uqonde imbangela futhi unikeze imithi efanele ukuze iphumelele kakhulu.
Isizathu sokukhiya izinsimbi zensimbi engagqwali kufanele sihlaziywe kusuka ezicini ezimbili: impahla kanye nokusebenza.
Ezingeni lempahla
Ngoba impahla yensimbi engagqwali inokusebenza okuhle kokunqanda ukugqwala, kodwa ukuthungwa kwayo kuthambile, amandla aphansi, futhi ukuqhutshwa kwe-thermal kubi. Ngakho-ke, phakathi nenqubo yokuqinisa, ukucindezela nokushisa okukhiqizwa phakathi kwamazinyo kuzolimaza ungqimba lwe-chromium oxide engaphezulu, okubangela ukuvinjelwa / ukugunda phakathi kwamazinyo, okubangela ukunamathela nokukhiya. Ukuphakama kokuqukethwe kwethusi kokokusebenza, kuthambisa ukuthungwa, futhi kuyanda namathuba okukhiya.
Izinga lokusebenza
Ukusebenza okungalungile ngesikhathi sokukhiya kungabangela nezinkinga "zokukhiya", njenge:
(1) I-engeli yokusetshenziswa kwamandla ayinangqondo. Phakathi nenqubo yokukhiya, ibhawodi kanye namantongomane kungase kutsheke ngenxa yokufaneleka kwawo;
(2) Iphethini yentambo ayihlanzekile, inokungcola noma izinto zangaphandle. Lapho amaphuzu we-welding nezinye izinsimbi zengezwa phakathi kwezintambo, cishe kubangele ukukhiya;
(3) Amandla angafanele. Amandla okukhiya asetshenzisiwe makhulu kakhulu, adlula ububanzi bokuthwala uchungechunge;
(4) Ithuluzi lokusebenza alifanelekile futhi isivinini sokukhiya sishesha kakhulu. Uma usebenzisa i-wrench kagesi, nakuba isivinini sokukhiya sishesha, sizokwenza ukuthi izinga lokushisa likhuphuke ngokushesha, okuholela ekukhiyeni;
(5) Awekho ama-gasket asetshenzisiwe.
