Ama-valve amabhizinisi azoba nomthelela wokuphela "kokushoda kwabasebenzi" izindinganiso ezibalulekile zobuchwepheshe

Amabhizinisi amavalvu abe nomthelela wokuphela "kokushoda kwabasebenzi" amazinga okhiye obuchwepheshe be-valve Ukusebenza kwamandla acindezelayo Ukusebenza kwamandla kwevalvu kusho ikhono levalvu ukuthwala ukucindezela kokusebenza kwendawo. I-valve kufanele ithwale ingcindezi yegesi yezimpahla zemishini, ngakho-ke kufanele ibe namandla anele nokuqina kokugoba, ukuqinisekisa ukuthi ukusetshenziswa kwesikhathi eside ngaphandle kokuqhekeka noma ukuguqulwa. Ukusebenza kokuvala Ukusebenza kokuvalwa kwe-valve kubhekisela endaweni yokuvala i-valve evimba ikhono lokuvuza eliphakathi nendawo, iyinkomba yenkomba yokusebenza kobuchwepheshe eyinhloko yevalvu. Indawo yokuvala i-valve inezindawo ezintathu: ukuxhumana phakathi kwezingxenye zokuvula nokuvala kanye ne-valve yesango lokucindezela okuphezulu; Izinto zokugcwalisa kanye nesihlalo se-valve kanye nokufanisa ngokuhlanganyela komkhono; Ukuhlangana kwepuleti lesekhethi kawoyela kanye nesivalo sevalvu. Engxenyeni yokuqala yokuvuza kubizwa ngokuthi ukuvuza, okuvame ukubizwa ngokuthi ukuvala, kuzolimaza ikhono le-valve lokunqamula okuphakathi. Kuma-valve okunqamula, ukuvuza kwangaphakathi akuvunyelwe. Ukuvuza okubili kokugcina kubizwa ngokuthi ukuchayeka, okungukuthi, ukuvuza okuphakathi nendawo kusuka kuvalvu kuya ngaphandle kwevalvu. Ukuchayeka kuzoholela ekulimaleni kwezinto ezingavuthiwe, ukungcoliswa kwemvelo, okubi nakakhulu kuzoholela ezingozini zokuphepha. Ezintweni ezivuthayo neziqhumayo, imidiya eyingozi noma ekhipha imisebe, ukuchayeka akuvunyelwe, ngakho-ke i-valve kufanele ibe nokusebenza okuzinzile kokuvala. I-Fluid medium Medium ngokusebenzisa i-valve izodala umonakalo wengcindezi (kokubili ngaphambi nangemva komehluko we-valve yokucindezela), okungukuthi, i-valve inokumelana okuthile kokungqubuzana kwe-fluidity ye-medium, okuphakathi ukuze kukhishwe ukumelana nokushayisana kwe-valve kuyodingeka. ukusebenzisa inani elithile lamandla e-kinetic. Kusukela ekucatshangelweni kwezinsiza, ukuklama nokukhiqizwa kwama-valve, ukunciphisa ukumelana nokungqubuzana kwe-valve ku-flow medium. Amandla okuvula nawokuvala kanye ne-torque Amandla okuvula nawokuvala kanye ne-torque amandla afanayo noma ama-torque okufanele anyuswe ukuze avule noma avale i-valve. Vala i-valve, kufanele wenze ingxenye evulekile-vala futhi uthumele ukukhiqiza ingcindezi ethile yokuvala phakathi kobuso obubili be-tu, ngasikhathi sinye futhi ukuqeda isihlalo nezinto zokugcwalisa, phakathi kwentambo yangaphandle kanye nesihlalo, ukusekelwa kwesihlalo. in friction kanye isikhundla sakhe phezulu ukungqubuzana beya, ngakho qiniseka ukwandisa kumele ucime amandla kanye torque, valve in inqubo yokuvula nokuvala, Amandla okuvula nokuvala edingekayo kanye torque yokuvula nokuvala ziyaguquguquka, futhi inani eliphezulu lisesikhathini sokugcina sokuvala noma umzuzu wokuqala wokuvulwa. Ama-valve kufanele aklanywe futhi enziwe ukuze kuncishiswe amandla okuvala kanye ne-torque yokuvala. Isivinini sokuvula/sokuvala Isivinini sokuvula nokuvala siboniswa yinkathi yesikhathi edingekayo endaweni eyodwa yokuvula noma yokuvala i-valve. Izinga elijwayelekile lokuvula nokuvala i-valve ngaphandle kokuphathwa okuqinile, kodwa kunezimo ezithile zokusebenza ekuvuleni nasekuvaleni izinga kunezidingo ezikhethekile, uma ezinye izinhlinzeko zivuleka ngokushesha noma zivala, ukuvimbela izingozi zokuphepha, ezinye izinhlinzeko zihamba kancane, ukuvimbela iziteleka zamanzi, okuyinto kufanele kucatshangelwe ekusetshenzisweni kwezinhlobo zama-valve. Ukuzwela kwe-Postural kanye nokuzinza Lokhu kuphinde kubhekisele kuvalvu yezinguquko eziyinhloko zepharamitha phakathi nendawo, ukukhombisa izinga elihambisanayo lokuba sengozini. Ku-valve yendlela eyodwa, i-valve elawula ingcindezi, i-valve elawulayo namanye ama-valve asetshenziselwa ukulungisa imingcele eyinhloko ye-medium kanye nama-valve ayo, i-valve ye-steam trap namanye anendima ekhethekile, ukuzwela kwawo nokuzinza kuyinkomba ebaluleke kakhulu yokusebenza kwezobuchwepheshe. inani. Isikhathi sokusebenzisa Ibonisa izinga eliqinile levalvu, inani eliyinhloko lenkomba yokusebenza kwevalvu, futhi linokubaluleka okukhulu okungokoqobo kwezenhlalo nezomnotho. Ngokuvamile kuboniswa imvamisa yokuvula nokuvala ukuze kuqinisekiswe izinga lokuqina, futhi kungaboniswa nesikhathi sesevisi. Valve amabhizinisi ukuba nomthelela ekupheleni "ukuntuleka kwabasebenzi" Valve amabhizinisi ukuba nomphumela ukushoda ekupheleni konyaka zabasebenzi " Eminyakeni yamuva, njalo ngonyaka ngasekupheleni kwalesi sikhathi, "ukuntuleka kwabasebenzi" like a inkani. isifo njengoba kwenzeka njalo, futhi ngaleyo ndlela kwaholela uchungechunge ukusabela ahlobene The valve izingxenye uchungechunge amasimu abasebenzi kakhulu, ukushoda kwezimali zabantu ngokushesha kuholela izingxenye valve amabhizinisi amaningi ukunciphisa ukukhiqizwa kanye nokukhiqiza, futhi ngisho ezinye. amabhizinisi alinge ukwamukela oda ngobumpumputhe, ukuze kuvinjwe inhliziyo evumayo futhi enganele, okuholela umonakalo omkhulu ukushoda kwabasebenzi eShayina akuyona into entsha, kusukela ekuqaleni eminyakeni emibili edlule ezindaweni ezisogwini olusempumalanga kanye nezifunda eziphambili ukushoda kwabasebenzi kanye. ubunzima bokuqasha, kanye nokushoda kwezabasebenzi ngo-2022 kuza ngaphambi kwesikhathi, kunolaka, amabhizinisi amaningi ama-valve akhathazekile Ekuhlaziyeni umbiko, ezinkampanini eziningi zezingxenye zama-valve ezweni lethu zinendlela yakamuva yokukhiqiza eyisidala, inzuzo ephansi yempahla, isidingo sabasebenzi. mkhulu, umqondo wokuphatha ophelelwe yisikhathi nokunye ukuhlaselwa; Futhi ezimpahleni ezithuthukisiwe kancane kancane zibe imakethe yokuthengisa yesikhathi esizayo kumele, inzuzo ebalulekile yokusebenza kwebhizinisi kanye nokusinda komkhuba wokuthuthukiswa kwendawo yasendlini, ngakho-ke ukudlala impi yentengo njengomncintiswano wemakethe ukuhola ingxenye yomoya yebhizinisi le-valve, ingqikithi yomoya eningi enesisindo selungelo lezisebenzi. Ukuqonda izinsiza ithalenta futhi ihlanganisa ukubaluleka okukhulu embonini noma akwanele, bazizwa nje ukunikeza iholo elanele, ezimele, ukuntuleka lolu hlobo umkhuba abakwazi ukusebenza, ibhizinisi ithalente donsa futhi ngokuvamile isimo sokuhamba evelele kakhudlwana, izici eziyinhloko. noma ukuntuleka kwesistimu yokuqasha amabhizinisi asheshayo, ukuntuleka kwamathalente nokuxhumana okulungile, Ngakolunye uhlangothi, izinguquko ezinjalo zikhuthaza amabhizinisi ukuthi anamathisele ukubaluleka okukhulu kumathalente amahle kakhulu futhi azame konke okusemandleni awo ukugcina amathalente. Uma sibheka imboni yama-valve ezweni lakithi, iyiphi indlela esingagcina ngayo amathalente? Ngicabanga ukuthi ukuhlala kuphela kufanele unake, ufuna ukugcina ithalente, ukuze uthole imali, okokuqala kufanele kube nohlelo lwentuthuko, vumela isisebenzi ebhizinisini sibe nenhloso yesikhathi eside, sibe nesibindi sokukulandela, simenze ngaphandle kokuziphilisa, okukhulu kakhulu noma ukusebenza, ukuqedela impilo yabo ekahle, unomgomo wesikhathi eside, yebo, ngizoshiya inhliziyo yokuhamba, Hhayi nje ukutshala imali ezibophweni zabo, ithalente, umdlandla kanye intsha; Futhi emisha yezobuchwepheshe, ukukhuthala okuqhubekayo kanye nenqubekelaphambili. Ngaphezu kwalokho, kuyadingeka futhi ukwakha ngenkuthalo ukwethembana okusebenzayo nokubambisana esikweni lebhizinisi nobuciko, ukuze babe namathuba amaningi okusebenzisa amathalenta abo futhi baqedele inani labo lokusebenzisa. Imikhiqizo yepompo ye-Ze de centrifugal eya esiphakamisini sendle, umshini wokuphakamisa amabhakede angcolile, isiteshi sokuphakamisa amanzi angcolile, isiteshi sepompo esididiyelwe, iphampu ephakamisa indle, imishini yokuphakamisa indle, iphampu yasengadini, iphampu yejet, impompo ye-centrifugal, isihlukanisi se-slag, iphampu yendle, iphampu yendle engaphansi kwamanzi njenge idivayisi ehamba phambili yokuphakamisa indle. Umshini ngamunye wokuphakamisa indle uklanyelwe ukuba ube lula kakhulu ukuwufaka, futhi ngesikhathi esifanayo, kunesethi ephelele yezingxenye ezisele ezidingekayo ukuze zifakwe. Sinekhava yokuthengisa emakethe ezwakalayo I-inthanethi, ingakulethela amaphrojekthi esevisi alula, eFrance, Isifunda saseYurophu, iningi lezwe lethu lingaqedela umgomo oseduze wokuthenga. Imishini yokuphakamisa indle ye-Ze de ilungele abantu abajwayelekile (umndeni), i-villa yomndeni owodwa, ingadi, izinsizakalo zezentengiselwano nezinye iziza, ezigxile epayipini lokudonsa amanzi elingaphansi kwe-villa, i-drainage efanayo yaphansi, ukuphakelwa kwamanzi okuphuza asekhaya, ukuchelela engadini kanye nezinye izingcweti. kanye nemishini edidiyelwe yokuthutha emanzini nezixazululo!
