Ukukhetha ukuthi yiluphi uhlobo lwesakhiwo senzwa yokukala ngokuyinhloko kuncike ohlelweni lokukala olusebenzisa imvelo kanye nesakhiwo sesikali.
Indawo yokusebenza yesistimu yokukala
Uma inzwa yokukala isebenza ngaphansi kwemvelo yokushisa okuphezulu, kufanele isebenzise izinzwa ezimelana nezinga lokushisa eliphezulu, ikakhulukazi izikhathi ezinokhahlo kufanele zengezwe ngokufaka ukushisa, ukupholisa amanzi noma izisetshenziswa zokupholisa umoya. inzwa esebenza endaweni yokushisa okuphezulu kufanele isebenzise izinzwa ezimelana nokushisa okuphezulu, ikakhulukazi izikhathi ezinokhahlo kufanele zengezwe ngokufakwa kokushisa, ukupholisa amanzi noma imishini yokupholisa umoya.
Imithelela yothuli, umswakama, nokugqwala
Imikhiqizo yochungechunge lwensimbi engagqwali ifanele umswakama wendawo> 80% RH ngaphezulu, kanye nenye i-asidi, i-ammonia corrosion;Imikhiqizo yensimbi ye-Glue sealing ilungele umswakama wemvelo < 65% RH ngaphandle kokungenwa kwamanzi, ayikho enye igesi egqwalayo, uketshezi. Imikhiqizo yensimbi yokutywina yokutywina ilungele umswakama osendaweni engu-< 80% RH, ene-drainage ebushelelezi, ayikho enye. igesi eyonakalisayo, i-liquid.Imikhiqizo yochungechunge lwe-Aluminium alloy ifanele umswakama wendawo ezungezile <65%RH.Akukho ukungena kwamanzi, ayikho enye igesi ebolayo, uketshezi
Ezinhlelweni zokukala eziphakeme, ukuphepha nokuvikela ukugcwala ngokweqile kufanele kubhekwe
Izinzwa ezivikela ukuqhuma noma izinzwa eziphephile ngaphakathi kufanele zikhethwe uma zisetshenziswa endaweni evuthayo neziqhumane.Isembozo sokuvala sezinzwa ezivikela ukuqhuma akufanele nje sicabangele ukungangeni kwayo umoya, kodwa futhi sicabangele amandla okuvikela ukuqhuma, kanye nokungangeni kwamanzi, umswakama-umswakama kanye nokuqhuma-ubufakazi bezintambo zezintambo njll.
Izidingo zezici zesakhiwo seplathifomu yesikali
1.Isikhala sokufaka isithwali.Kwezinye izindawo ezinomkhawulo wesikhala, umkhawulo wesikhala kufanele ucatshangelwe lapho kukhethwa inzwa yokukala.
2.Kulula ukufaka nokunakekela.Kungakhathaliseki ukwethembeka kwanoma iyiphi imishini, kuyadingeka ukucabangela inkinga yokufaka nokugcinwa.Ngaphezu kokunethezeka kokufakwa, kuyadingeka futhi ukuthi ucabangele ukuthi ukugcinwa kulula yini ukusetshenziswa nokuthi ngabe inzwa yokukala ikulungele yini ukushintshwa.
3.Umphumela wamandla asemaceleni.Lapho ukhetha inzwa yesisindo, kuyadingeka ukucabangela ukuthi inkundla yesikali inamandla asemaceleni asetshenziswayo.Inzwa yesisindo eklanyelwe ngokuvumelana nesimiso sokucindezeleka kwe-shear inamandla aqinile okumelana namandla ahlangene, kuyilapho inzwa yesisindo eklanywe ngesimiso sokucindezeleka esivamile inamandla abuthakathaka okumelana namandla ahlangene.
4. Izinkinga zokuqina kwabathwali bomthwalo, ingqalasizinda kanye nezinsiza.Ukuqina kwalezi zakhiwo kuzothinta ngokuqondile inani lokuguqulwa futhi ngaleyo ndlela kuthinte ukunemba kokulinganisa.
5.Ithonya lokushisa endaweni yesikali.Kuzinhlelo zokukala zangaphandle ezinamadivaysi amade okuthwala kanye nendawo enkulu, njengesikali samaloli kanye nethangi elikhulu lezinto ezibonakalayo, i-coefficient yokwandisa yedivayisi yokuthwala kufanele icatshangelwe.
Khetha inombolo yezinzwa zokukala
Ukukhethwa kwenombolo yezinzwa zokukala kusekelwe enjongweni yesistimu yokukala kanye nenani lamaphuzu adingekayo ukuze kusekelwe isiteji sesikali (inani lamaphuzu kufanele linqunywe ngokuvumelana nesimiso sokuthi isikhungo sejiyomethri sokuvuthwa kwesikali futhi isikhungo sangempela samandla adonsela phansi siyaqondana).Ngokuvamile, inkundla yesikali inamaphuzu ambalwa okusekela ekukhethweni kwezinzwa ezimbalwa.
Ukukhetha ububanzi bebanga lezinzwa zokukala
Ukukhethwa kobubanzi benzwa yesisindo kunganqunywa ngokusho kokuhlolwa okuphelele kwenani eliphakeme lesisindo sesikali, inani lezinzwa ezikhethiwe, isisindo seplatifomu yesikali ubukhulu bomthwalo ongase ube ingxenye nomthwalo oguquguqukayo.Uma sikhuluma ngokwethiyori, lapho inani lesisindo sohlelo lokukala lisondelana nomthamo olinganiselwe wenzwa, kulapho ukunemba kwesisindo kuzoba phezulu.Kodwa-ke, ekusebenzeni, ngenxa yobukhona besisindo, isisindo se-tare, ukudlidliza, umthelela, kanye nomthwalo oyingxenye wesilinganiso, isimiso sokukhetha umkhawulo wezinzwa wezinhlelo zokukala ezahlukene zehluke kakhulu.
Amazwana:
Lapho ukhetha umthamo olinganiselwe wenzwa, kungcono ukuhambisana nenani lochungechunge lomkhiqizo olujwayelekile lomkhiqizi ngangokunokwenzeka, ngaphandle kwalokho, ukukhethwa kwemikhiqizo engeyona evamile, hhayi kuphela i-ost ephezulu, kodwa futhi kunzima ukuyibuyisela ngemva kokulimala.
Kuhlelo olufanayo lokukala, akuvunyelwe ukukhetha izinzwa zamandla ezilinganiselwe ezihlukene, ngaphandle kwalokho, uhlelo alukwazi ukusebenza ngokujwayelekile.
Ukukhetha ileveli yokunemba kwenzwa yokukala
Izinga lokunemba liyinkomba yokusebenza ebalulekile yenzwa, futhi iyisixhumanisi esibalulekile esihlobene nokunemba kokulinganisa kwalo lonke uhlelo lokulinganisa.Ukukhuphuka kwezinga lokunemba kwenzwa yokukala, intengo ibiza kakhulu.Ngakho-ke, inqobo nje uma ukunemba kwenzwa kuhlangabezana nezidingo zokunemba zalo lonke uhlelo lokulinganisa, asikho isidingo sokukhetha eziphakeme kakhulu.Ukukhethwa kwezinga lenzwa kufanele kuhlangabezane nezimo ezimbili ezilandelayo:
Ukuze uhlangabezane nemfuneko yokufaka inkomba enesisindo
Okusho ukuthi, isignali yokuphuma kwenzwa kufanele ibe nkulu noma ilingane nenani lokuzwela okokufaka elidingwa inkomba.
Landela imfuneko yokunemba kwesilinganiso sonke se-elekthronikhi
Ngaphezu kokuhlangabezana nezidingo zokufaka zenkomba, ibanga lenzwa yesisindo nalo lidinga ukuhlangabezana nezidingo zokunemba zaso sonke isikali sikagesi.
Ngokuvamile, isikali sikagesi sakhiwe izingxenye ezintathu: isiteji sesikali, inzwa yokukala kanye nenkomba.Uma ukhetha ukunemba kwenzwa yokukala, ukunemba kwenzwa yokukala kufanele kube kukhulu kancane kunevelu yokubala yetiyori.Kodwa-ke, ngenxa yokuthi ithiyori ivamise ukukhawulelwa yizimo zenhloso, isibonelo, amandla enkundla yesikali angaphansi kwalawo yenani lokubala lethiyori.Ukusebenza kwenkomba akukuhle kakhulu, indawo yokusebenza yesilinganiso imbi kakhulu njalonjalo.Izizathu zithinta ngokuqondile ukunemba kwesilinganiso, ngakho-ke kufanele sithuthukise izidingo ezivela kuzo zonke izici, hhayi nje ukucabangela izinzuzo zezomnotho, kodwa futhi nokuqinisekisa ukuthi inhloso yokulinganisa.
