Indima yoMzimba weValve kwiNkqubo yoLawulo lweMizi-mveliso kunye nokuqwalaselwa koKhetho

Umzimba wevalvu yeyona nxalenye ilula kwaye kulula ukuyihoya kwivalvu. Ulwakhiwo lubonakala lulula, eneneni, ukusuka kwindlela yokuphosa, ukukhethwa kwezinto ukuya kubungakanani obuchanekileyo, zonke ezi zinto zigqiba ukuba ivalvu ingasebenza ixesha elide ngaphandle kokuvuza, ngaphandle kokuguquka.

Sibone iingxaki ezininzi zeevalvu kwintsimi phezu komphezulu weendawo zangaphakathi zokuguguleka, eneneni, unobangela kukuba umzimba wevalvu awanelanga ukuba lukhuni, okanye ubukhulu bodonga olungalinganiyo bomngxuma wangaphakathi obubangela uxinzelelo. Ingakumbi xa kukho umahluko ophezulu woxinzelelo okanye ukutshintsha kwamaza aphezulu, umzimba wevalvu awuzinzanga phantsi koxinzelelo, kwaye kwenzeka utshintsho oluncinci emva kwexesha elide, okubangela ukuguguleka kwe-spool bias, ukungalungelelani komgca wokutywina, emva koko kuvuza okanye kume.

Kukwakho nengxaki yokwenyani kukuba abavelisi abaninzi ukuze bonge iindleko, kwiimeko ezingezizo ezisemgangathweni besebenzisa ngqo umzimba wevalvu yemveliso yomngundo endala, isiphumo kukuba iflange ayivumelekanga ukuba ijongane nayo, indawo yomngxuma wevalvu ayanelanga, indibano yesihlalo sevalvu ayikho endaweni yayo kwaye kukho iingozi ezininzi ezifihlakeleyo, kwaye ekugqibeleni inokuxhomekeka kuphela ekuwelding nasekugayweni kwindawo, 'ukulungisa ukufakelwa'. Oku kwisityalo samandla, ishishini leekhemikhali alivumeli inkqubo yexesha elide lokungasebenzi, yingozi enkulu kakhulu efihliweyo.

Ukususela kwizinto ezisetyenzisiweyo, i-WCB eqhelekileyo, i-CF8, i-CF8M, i-2205 duplex steel, i-316, i-304, kwane-F51, njl.njl., ukukhetha izinto ezingalunganga kulula nje ukubola yi-medium, kodwa nakwiindawo ezishushu nezibandayo zokuqhekeka okanye ukusilela koxinzelelo. Sakha sabona kwiprojekthi ye-chlor-alkali, umzimba wevalvu owenziwe nge-CF8M osebenza isiqingatha sonyaka umngxuma wangaphakathi ubenemingxunya yokubola, kwaye kamva saqinisekisa ukuba umbhobho one-ions ze-chlorine kuxinzelelo lokufuma uphezulu kakhulu kunexabiso loyilo.

Ngokwesakhiwo, umzimba wevalvu akufuneki nje kuphela uxinzelelo, ubushushu, kodwa uvumelane nendlela yokufakela yangaphakathi. Umzekelo, umzimba wevalvu yebhola kufuneka ube nobukhulu obaneleyo bodonga ukuxhasa ukutyhala kwe-axial, umzimba wevalvu yebhabhathane kufuneka uqwalasele indawo yokugoba iringi yokutywina, umzimba wevalvu yesango kufuneka ulawule ukuchaneka kwesikhokelo sepleyiti yesango, ezi azizo nje imizobo embalwa engacwangciswanga.

I-One Lime Machinery iqokelele amava amaninzi kwiprojekthi yokwenza umzimba weevalvu, igubungela ukusuka kwiivalvu ezincinci zezixhobo ukuya kwimizimba yeevalvu zebhola ezinzima ezingama-intshi ezingama-24, ixhasa ukuphoswa ngokuchanekileyo, ulawulo lobukhulu beqokobhe, ukuqhumisa isanti kumphezulu kunye novavanyo olungonakalisiyo lweemingxuma zeevalvu. Sinikezela ngoluhlu olubanzi lwezinto ezisetyenziswayo ezifana ne-CF8M, i-WCB, i-2205, njl.njl., kwaye sixhasa utshintsho olwenziwe ngokwezifiso kunye neprototyping ngokwesakhiwo esixhasayo somthengi.

Ukuqukumbela, nangona umzimba wevalvu ungengawo awona malungu abiza kakhulu, kodwa iseti epheleleyo yeevalvu inoku "thwala" umbindi. Kucetyiswa ukuba abasebenzi boyilo lobunjineli kunye nokuthengwa, kwasekuqaleni kweprojekthi ukuze bacacise iiparameter zomzimba wevalvu, iifom zonxibelelwano kunye neemfuno zesakhiwo somngxuma, bangalindi de kube kuxinzelelo lokudibanisa okanye lovavanyo kuphela baze bafumane ukuba 'ayinakufakelwa' okanye 'phezulu'.
