Igumbi elihlanzekile linemithetho eqinile ngokushisa kwemvelo, umswakama, umthamo womoya omusha, ukukhanya, njll., okuqinisekisa ikhwalithi yokukhiqizwa kwemikhiqizo kanye nenduduzo yendawo yokusebenza yabasebenzi. Lonke uhlelo lwegumbi elihlanzekile lufakwe uhlelo lokuhlanza umoya olunezigaba ezintathu olusebenzisa izihlungi zokuqala, eziphakathi kanye neze-hepa ukulawula inani lezinhlayiya zothuli kanye nenani lamagciwane okuthuthwa kanye namagciwane antantayo endaweni ehlanzekile. Isihlungi se-hepa sisebenza njengedivayisi yokuhlunga yokugcina yegumbi elihlanzekile. Isihlungi sinquma umphumela wokusebenza kwesistimu yonke yegumbi elihlanzekile, ngakho-ke kubaluleke kakhulu ukuqonda isikhathi sokushintsha kwesihlungi se-hepa.
Ngokuphathelene nezindinganiso zokufaka esikhundleni izihlungi ze-hepa, amaphuzu alandelayo afingqiwe:
Okokuqala, ake siqale ngesihlungi se-hepa. Ekamelweni elihlanzekile, kungakhathaliseki ukuthi isihlungi se-hepa esikhulu esifakwe ekugcineni kweyunithi yokupholisa umoya noma isihlungi se-hepa esifakwe ebhokisini le-hepa, lezi kumele zibe namarekhodi esikhathi sokusebenza anembile njalo, ukuhlanzeka kanye nomthamo womoya kusetshenziswa njengesisekelo sokushintsha. Isibonelo, ngaphansi kokusetshenziswa okuvamile, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu konyaka owodwa. Uma ukuvikelwa kwangaphambili kwenziwe kahle, impilo yesevisi yesihlungi se-hepa ingaba yinde ngangokunokwenzeka. Ngeke kube nenkinga nhlobo iminyaka engaphezu kwemibili. Vele, lokhu kuncike nasezingeni lesihlungi se-hepa, futhi kungaba yinde;
Okwesibili, uma isihlungi se-hepa sifakwe emishinini ehlanzekile yegumbi, njengesihlungi se-hepa eshaweni yomoya, uma isihlungi esiyinhloko sangaphambili sivikelwe kahle, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu kweminyaka emibili; njengokuhlanza isihlungi se-hepa etafuleni, singasishintsha isihlungi se-hepa ngokusebenzisa izinkomba zegeyiji yokucindezela ebhentshini elihlanzekile. Ngesihlungi se-hepa esiku-laminar flow hood, singanquma isikhathi esingcono kakhulu sokushintsha isihlungi se-hepa ngokuthola ijubane lomoya lesihlungi se-hepa. Isikhathi esingcono kakhulu, njengokushintsha isihlungi se-hepa kuyunithi yesihlungi sefeni, ukufaka isihlungi se-hepa ngokusebenzisa izinkomba ohlelweni lokulawula lwe-PLC noma izinkomba ezivela ku-geyiji yokucindezela.
Okwesithathu, abanye babafaki bethu bezihlungi zomoya abanolwazi bafingqe ulwazi lwabo olubalulekile futhi bazokwethula lapha. Sithemba ukuthi kungakusiza ukuthi uqonde kangcono isikhathi esingcono kakhulu sokushintsha isihlungi se-hepa. Isilinganiso sokucindezela sibonisa ukuthi lapho ukumelana kwesihlungi se-hepa kufinyelela izikhathi ezimbili kuya kwezingu-3 zokumelana kokuqala, ukulungiswa kufanele kumiswe noma isihlungi se-hepa kufanele sishintshwe.
Uma kungekho i-pressure gauge, unganquma ukuthi idinga ukushintshwa ngokusekelwe esakhiweni esilandelayo esilula esinezingxenye ezimbili:
1) Hlola umbala wezinto zokuhlunga ezinhlangothini eziphezulu nezingezansi zesihlungi se-hepa. Uma umbala wezinto zokuhlunga ohlangothini lokukhipha umoya uqala ukuba mnyama, lungela ukuwushintsha;
2) Thinta izinto zokuhlunga ebusweni bokuphuma komoya wesihlungi se-hepa ngezandla zakho. Uma kunothuli oluningi ezandleni zakho, lungela ukulishintsha;
3) Qopha isimo sokufakwa esikhundleni sesihlungi se-hepa izikhathi eziningi bese ufingqa umjikelezo wokufakwa esikhundleni ofanele kakhulu;
4) Ngaphansi kwesisekelo sokuthi isihlungi se-hepa asikafiki ekumelaneni kokugcina, uma umehluko wokucindezela phakathi kwegumbi elihlanzekile negumbi eliseduze wehla kakhulu, kungenzeka ukuthi ukumelana kokuhlunga okuyinhloko nokuphakathi kukhulu kakhulu, futhi kuyadingeka ukulungiselela ukushintshwa;
5) Uma ukuhlanzeka ekamelweni elihlanzekile kwehluleka ukuhlangabezana nezidingo zomklamo, noma kukhona ingcindezi engemihle, futhi isikhathi sokushintsha izihlungi eziyinhloko neziphakathi singakafinyelelwa, kungenzeka ukuthi ukumelana kwesihlungi se-hepa kukhulu kakhulu, futhi kuyadingeka ukulungiselela ukushintshwa.
Isifinyezo: Ngaphansi kokusetshenziswa okuvamile, izihlungi ze-hepa kufanele zishintshwe njalo eminyakeni emi-2 kuya kwemi-3, kodwa le datha iyahlukahluka kakhulu. Idatha eyisisekelo ingatholakala kuphela kuphrojekthi ethile, futhi ngemva kokuqinisekiswa kokusebenza kwegumbi elihlanzekile, idatha eqinisekisiwe efanele igumbi elihlanzekile inganikezwa kuphela ukuze isetshenziswe eshaweni lomoya lalelo gumbi elihlanzekile.
Uma ububanzi bokusetshenziswa bunwetshwa, ukuphambuka kwesikhathi sokuphila akunakugwenywa. Isibonelo, izihlungi ze-hepa emakamelweni ahlanzekile njengezindawo zokusebenzela zokupakisha ukudla kanye namalebhu ziye zahlolwa futhi zashintshwa, futhi impilo yesevisi ingaphezu kweminyaka emithathu.
Ngakho-ke, inani elibonakalayo lokuphila kwesihlungi alinakwandiswa ngokungahleliwe. Uma ukwakheka kohlelo lwegumbi elihlanzekile kungenangqondo, ukwelashwa komoya omusha kungekho, futhi uhlelo lokulawula uthuli lweshawa lomoya wegumbi elihlanzekile aluhambisani nesayensi, impilo yesevisi yesihlungi se-hepa ngokuqinisekile izoba mfushane, futhi ezinye kungadingeka zishintshwe ngemva kwesikhathi esingaphansi konyaka sokusetshenziswa.
Isikhathi sokuthunyelwe: Novemba-27-2023
