Ukuqonda Umsebenzi Wokuhlolwa Okushisiwe Kwe-Choke Manifold
Embonini kawoyela negesi, ukubaluleka kokuhlolwa kwemithombo akukwazi ukweqiwa. Ukuhlola umthombo kuyinqubo ebalulekile evumela abaqhubi ukuthi bahlole ukukhiqiza komthombo namandla. Ingxenye ebalulekile yokuhlolwa komthomboukuminyanisa okunengi, edlala indima ebalulekile ekulawuleni ukugeleza koketshezi emthonjeni. Ngokuqondene,umthombo oshisayo uminyanisa ngokuphindaphindiweyakhelwe ukubhekana nezinselele eziyingqayizivele ezilethwa imisebenzi yokuhlola umthombo wokushisa okuphezulu. Kule bhulogi, sizobhekisisa ukusebenza kwangaphakathi kweisivivinyo somthombo oshisiwe siminyanisa ngokuphindaphindiwefuthi uhlole ukuthi isebenza kanjani ukuze kuqinisekiswe ukuphepha nokusebenza kahle kwemisebenzi yokuhlola umthombo.
Okokuqala, kubalulekile ukuqonda injongo eyisisekelo yokuminyanisa okuhlukahlukene. Ekuhlolweni komthombo, ukuminyanisa okuhlukahlukene kusetshenziselwa ukulawula ukugeleza koketshezi olusuka emthonjeni, okuvumela opharetha ukuthi alawule ingcindezi nokugeleza ngesikhathi sokuhlolwa. Lokhu kubalulekile ekugcineni ubuqotho bomthombo kanye nokuqinisekisa ukuphepha kwabasebenzi kanye nemishini. Esimeni sokuhlolwa komthombo wokushisa okuphezulu, ukuminyanisa okujwayelekile okujwayelekile kungase kungafaneleki ngenxa yezimo ezimbi kakhulu ezihilelekile. Kulapho kungena khona ukuhlolwa komthombo oshisisiwe kaningi.
Ukushisisa kahle ukuminyanisa okuhlukahlukenezenzelwe ukuhlangabezana nezinselele zokuhlola umthombo wokushisa okuphezulu. Esinye sezici eziyinhloko zalolu hlobo lwe-throttling manifold amandla alo okumelana nezinga lokushisa eliphezulu ngaphandle kokuphazamisa ukusebenza kwawo. Lokhu kufinyelelwa ngokusebenzisa izinto ezikhethekile kanye nokwahlukanisa ukuze kuvikelwe inqwaba ekushiseni okukhiqizwa ngesikhathi sokuhlolwa. Ngaphezu kwalokho, ukushisisa kahle kokuhlola ukuminyanisa okuhlukahlukene kufakwe izinto zokushisisa ezigcina i-viscosity yoketshezi futhi zivimbele ukwakheka kwama-hydrates noma upharafini ongavimbela ukugeleza koketshezi oluvela emthonjeni.
Ngokusebenza,umthombo oshisayo uminyanisa ngokuphindaphindiweisebenza ngokufana nokuminyanisa okujwayelekile okuhlukahlukene kodwa kunomsebenzi owengeziwe wokulawula izinga lokushisa eliphezulu. Ukuminyanisa okuhlukahlukene kulawula ukucindezela nokugeleza ngokulungisa usayizi we-valve yokuminyanisa njengoba uketshezi lugeleza lusuka emthonjeni. Lokhu kubalulekile ukuvimbela izimo zokucindezela ngokweqile nokugcina izimo zokugeleza ezidingekayo ngesikhathi sokuhlolwa. Ngisho nasezindaweni ezinezinga lokushisa eliphezulu ngokwedlulele, izinto zokushisisa ngaphakathi kokuningi ziqinisekisa ukuthi uketshezi lugcinwa emazingeni okushisa afanele ukuze kugeleze kahle.
Ukwengeza, ama-multifold test okuminyanisa okushisa afakwe izici zokuphepha ukuze kuncishiswe izingozi ezihlobene nokuhlolwa kwemithombo yokushisa ephezulu. Lokhu kuhlanganisa amasistimu okuqapha ingcindezi, izindlela zokuvala ucingo ezimeni eziphuthumayo, kanye nezinhlelo zokuvikela ukushisa ukuze kuvikelwe abasebenzi namathuluzi emazingeni okushisa aphezulu. Lezi zinyathelo zokuphepha zibalulekile ekuqinisekiseni ukuthi imisebenzi yokuhlola kahle ingenziwa ngokwethembeka nangokuphepha ngisho nangaphansi kwezimo eziyinselele.
Kafushane, ukushisisa kahle ukuminyanisa umthombo wokuhlola kuyisici esibalulekile semisebenzi yokuhlola umthombo wokushisa okuphezulu. Lokhu okuhlukahlukene kokuminyanisa okukhethekile kudlala indima ebalulekile empumelelweni yemikhankaso yokuhlola umthombo ngokunikeza izindlela zokulawula ukugeleza koketshezi, ukugcina amazinga okushisa asezingeni eliphezulu nokuqinisekisa ukuphepha. Ukuqonda imisebenzi namandla ayo kubalulekile kunoma ngubani obambe iqhaza embonini kawoyela negesi njengoba igcizelela ukubaluleka kokusebenzisa imishini efanelekile emsebenzini, ikakhulukazi ezindaweni ezinesidingo.
