Izibonelo zohlelo lokusebenza lweUhlobo lwesiqeshana sesiShayina amavalvu ovemvane asebenza kahlekumaphrojekthi wobunjiniyela
Ngokuyinkimbinkimbi nokuhlukahluka kwamaphrojekthi wobunjiniyela besimanje, ama-valve, njengemishini ebalulekile yokulawula uketshezi, ukusebenza kwawo kanye nokusebenza kwawo kuthinta ngqo ukuphepha, ukwethembeka, kanye nomnotho wayo yonke iphrojekthi. Eminyakeni yamuva nje, ama-valve evemvane ohlobo lwe-clamp asebenza kahle kakhulu asetshenziswe kabanzi kumaphrojekthi wobunjiniyela ahlukahlukene ngenxa yezimpawu zawo ezihlukile zesakhiwo nokusebenza okuphakeme. Lesi sihloko sizohlola izibonelo zohlelo lokusebenza lweUhlobo lwesiqeshana sesiShayina amavalvu ovemvane asebenza kahlekumaphrojekthi wobunjiniyela, ukuze kunikezwe ireferensi yokukhethwa nokusebenzisa amaphrojekthi wobunjiniyela ahlobene.
1. Isizinda sephrojekthi kanye nendlela yokukhetha yamavalvu ovemvane ohlobo lwesiqeshana esisebenza kakhulu
Inkampani ye-petrochemical yakha isitshalo esisha se-ethylene esinomphumela wonyaka wamathani ayizigidi ezingu-1, okubandakanya inani elikhulu lemishini yokulawula uketshezi. Lapho likhetha okokusebenza kwe-valve, ithimba lephrojekthi licabangele ngokugcwele izici ezifana nokusebenza kwemishini, ukwethembeka, ukuphepha, kanye nokusebenza kalula nokunakekelwa, futhi ekugcineni lakhetha uhlobo lwe-wafer yase-Chinese esebenza kahle kakhulu. Imibandela yokukhetha ihlanganisa ikakhulukazi amaphuzu alandelayo:
(1)I-China inomsebenzi omuhle kakhulu wokuvala wamavalvu ovemvane ohlobo lwe-clamp asebenza kahle kakhulu, okungaqinisekisa ukunemba nokuzinza kokulawula uketshezi.
(2) I-China inesivinini esikhulu sokusebenza nokuthembeka kwamavalvu ovemvane ohlobo lwe-clamp asebenza kahle, angahlangabezana nokuma kokuqala okusheshayo kanye nezidingo zokusebenza ezivamile zamaphrojekthi wobunjiniyela.
(3) I-China inempilo ende yesevisi yamavalvu ovemvane ohlobo lwe-clamp asebenza kahle kakhulu, okunciphisa izindleko zokushintshwa nokugcinwa kwemishini.
(4) Amavalvu ovemvane ohlobo lweziqeshana ezisebenza kahle kakhulu anokumelana nokugqwala okuhle nokungagugi, futhi afanelekela izindawo zokusebenza ezinokhahlo njengamakhemikhali kaphethroli.
2. Izibonelo zohlelo lokusebenza zeUhlobo lwesiqeshana sesiShayina amavalvu ovemvane asebenza kahlekumaphrojekthi wobunjiniyela
(1) Ukufakwa kwe-ethylene plant
Kunemishini eminingi ebalulekile ehilelekile esitshalweni se-ethylene, njengezithando zomlilo eziqhekekayo, ama-compressor, ama-coolers, njll. Ama-valve ovemvane ohlobo lwe-clamp asebenza kakhulu adlala indima ebalulekile kule mishini. Ohlelweni lokushiswa kwezithando zomlilo, uhlobo lwe-clamp yase-China olusebenza kahle kakhulu lwe-butterfly valve lungafinyelela ukulawula okunembile kwegesi yamafutha (njengegesi yemvelo, i-petroleum gas eliquefied, njll.), ukuqinisekisa ukuzinza nokuphepha kokuvutha; Endaweni yokungena nokuphuma kwama-compressor, uhlobo lwe-clamp yase-China olusebenza kahle kakhulu lwevamvane lungafinyelela ukuqalisa kokumisa ngokushesha kanye nokulawulwa kokugeleza kwama-compressor, kuthuthukise ukusebenza kahle kwama-compressor.
(2) Isicelo kuyunithi yokuqhekeka kwe-catalytic
Iyunithi yokuqhekeka kwe-catalytic ingenye yezinto ezibalulekile ekuhluzeni, futhi uhlobo lwesiqeshana sase-China amavalvu ovemvane asebenza kahle nawo asetshenziswa kakhulu kumayunithi abangela ukuqhekeka. Ezindaweni ezifana nesikhuphukeli, umbhoshongo wokuhlukanisa, nombhoshongo wokuhlubula,Uhlobo lwe-clamp yaseShayina iveluvu yevemvane esebenza kahle kakhuluingafinyelela ukulawulwa okunembile koketshezi, iqinisekise ukusatshalaliswa okufanayo kwama-catalyst kanye nokusebenza kahle kokusabela, futhi ithuthukise isivuno somkhiqizo kanye nekhwalithi.
(3) Isicelo kubunjiniyela bokuhlanza indle
Kubunjiniyela bokuhlanza indle,I-China futhi idlala indima ebalulekile ohlotsheni lwe-clamp ama-valve uvemvane asebenza kahle . Ezindaweni ezinjengamathangi okukhipha umoya, amathangi okuthungatha indle, namathangi okugxilisa udaka, amavalvu evemvane ohlobo lwe-clamp yaseShayina asebenza kahle angakwazi ukufinyelela ukulawula ukugeleza kanye nokulawulwa kokungenisa umoya kokukhucululwa kwendle, akhuthaze ukubola kwendle nokugxilwa kwendle, futhi athuthukise ukusebenza kahle kokuhlanza indle.
3. Izinzuzo zohlobo lwe-clamp yase-China yamavalvu evemvane asebenza kahle kumaphrojekthi wobunjiniyela
(1) Ukwenza ngcono ukuphepha kwephrojekthi
Ukusebenza okuhle kakhulu kokuvalwa kweAmavalvu evemvane ohlobo lwe-clamp asebenza kahle kakhuluingaqinisekisa ukunemba nokuzinza kokulawula uketshezi, inciphise ngempumelelo izingozi zokuvuza, futhi ithuthukise ukuphepha kobunjiniyela.
(2) Ukuthuthukisa ukusebenza kahle kwephrojekthi
Isivinini esikhulu sokusebenza saseShayina kanye nokuthembeka kohlobo lwe-clamp amavalvu ovemvane olusebenza kahle lungahlangabezana nokuma kokuqala okusheshayo kanye nezidingo zokusebenza ezivamile zamaphrojekthi wobunjiniyela, futhi kuthuthukise ukusebenza kahle kwemishini.
(3) Yehlisa izindleko zokulungisa izinto zokusebenza
I-China inempilo ende yesevisi yamavalvu ovemvane ohlobo lwe-clamp asebenza kahle kakhulu, inciphisa izindleko zokushintshwa kwemishini kanye nokuyilungisa, kanye nokonga ukutshalwa kwezimali kumaphrojekthi wobunjiniyela.
(4) Ukuzivumelanisa nezimo zokusebenza nezimo ezicindezelayo
Ama-valve ovemvane ohlobo lwe-clip asebenza kahle anokumelana nokugqwala okuhle nokungagugi, alungele izindawo zokusebenza ezinokhahlo njengamakhemikhali e-petrochemical, ukuze kuqinisekiswe ukusebenza okuvamile kwemishini.
Ngokufigqiwe,Amavalvu evemvane ohlobo lwe-clamp asebenza kahle kakhulu babe namathemba abanzi okusebenza kumaphrojekthi wobunjiniyela. Izici zabo eziyingqayizivele zesakhiwo nokusebenza okuphezulu kunikeza izixazululo eziphephile, ezinokwethenjelwa, nezisebenzayo zokulawula uketshezi kumaphrojekthi ahlukahlukene wobunjiniyela.
