Izisekelo
Ngaphezu kwamanye amadivayisi wezimboni, izinzwa zokucindezela / izidluliseli zokucindezela / ukuhanjiswa kwengcindezi, zisetshenziswa kaningi ngokuhlangana nezinsimbi ezihambisanayo, njengezishintsheli zokucindezela, amageji wengcindezi, kanye nezilawuli zengcindezi yedijithali. Ngokwengezwa kwalawa madivayisi, izidlulisi zokucindezela zandisa ukungazinzi ngaphandle kwamaphutha akhiqizwe kusuka kuzinsimbi zamandla ezimboni ngenxushunxushu kazibuthe. Bangaphinde bahlonyiswe nokuxhumana kukagesi okuzwakala ama-alamu, kuvule amalambu esignali, noma ukulawula i-valve noma ipompo. Izibonelo ezimbili ezithile zezesekelo ezisetshenziselwa ukukhulisa ukusebenza kwama-gauge ngama-adaptha wokuhlola nama-gauge ahlukanisiwe. Ama-adaptha wephoyinti lokuhlola afanela ama-gauges futhi awavumela ukuthi ashaye amaphuzu ahlukahlukene ngaphakathi kohlelo, ukunika amandla okulinganisa okucindezela kokuhlolwa ngaphandle kokuthengwa kwama-gauge amaningi, ahlukene. Abahlukanisi be-Gauge baphendula igeji yengcindezi ibe yindlela "e-on / off" ngokunyuka phakathi kwegeji nesekethe yayo; ngaphandle kokuthi inkinobho isebenze, igeji ngeke ivezwe futhi ngeke ifunde ingcindezi yoketshezi.
Izisekeli eziningi zezidlulisi zokucindezela zinezinhloso zokuvikela. Njengezinsimbi zezimboni eziyinkimbinkimbi, izidlulisi zokucindezela zibhekene nezinsongo ezahlukahlukene ezinjengokudlidliza kwamapayipi, ukucindezelwa kwamanzi, njll. I-gauge isolator eshiwo ngenhla isebenza nomsebenzi wokuphepha ngokuvikela indlela yangaphakathi yokudlulisa ingcindezi kusuka ku-sud. den spikes yengcindezi. Ama-snubber dampers ahlinzeka ngomsebenzi ofanayo ngokunciphisa ukuguquguquka okukhulu kwengcindezi. Abavikeli abahlukahlukene bangathengwa ukuvikela ingaphandle legeji ekushaqekeni okunzima, ngenkathi izimpawu zamakhemikhali ziyatholakala ukuvikela izidlulisi zokucindezela ekugcineni noma kufakwe phansi. Ngenkathi izilinganiso zengcindezi ngokuvamile zingadingi izinga eliphakeme lokugcinwa, Ukutshala imali kumasekeli okuvikelayo kungenye yezinto ezinhle kakhulu abasebenzisi be-gauge abangakwenza ukuvikela nokunweba impilo yegeji.
Ukucatshangela
Lapho ukhetha isidlulisi sengcindezi sokusebenza okuthile, kufanele kucatshangelwe izinto eziningana. Okunye kokucatshangelwa okukhulu kufaka phakathi usayizi wokudayela, usayizi wokuxhuma noma ichweba elizosetshenziswa igeji, amayunithi wokulinganisa umdlulisi wengcindezi akwaziyo (e. g. I-PSI, mmHg, PA, njll.), ukuhambisana kwezinto zegaji nezimo zokusebenza (kufaka phakathi izinga lokushisa, ukuwohloka, njll.).. Nokuthi ngabe igeji kufanele yome noma igcwaliswe ngoketshezi (le yokugcina ivame ukuba nempilo ende ngenxa yokumunca okushaqisayo).
Esinye sezici ezibaluleke kakhulu okufanele sicatshangelwe uhla lwengcindezi. Ngokuvamile, kufanele usebenzise isidlulisi sokucindezela esikwazi ukufunda okungenani kabili inani lengcindezi yokusebenza okulindelekile. Lokhu kunikeza umkhawulo onengqondo wokuphepha wokusebenzisa umdlulisi wengcindezi. Njengomthetho wesithupha, ingcindezi yokusebenza akufanele neze ihambe ngaphezu kwezine ezintathu zebanga lokufunda lokudlulisa ingcindezi. I-corollary yemithetho yesithupha ebandakanya ingcindezi ukubaluleka kokukhetha amageji wengcindezi eqondene nezicelo. Izinhlelo ze-Hydraulic, ngokwesibonelo, kufanele zisebenzise kuphela ama-hydraulic gauges aklanyelwe ukusebenza ngaphansi kwezimo ezijwayelekile ezindaweni ze-hydraulic.
Ngokunemba okukhulu kakhulu - kanye nejubane elikhulu, ukuthembeka, nokuqina - izidlulisi zokucindezela zedijithali kufanele zisetshenziswe esikhundleni samadivayisi wengcindezi (yize izindleko zazo ezishibhile). Khumbula, nokho, ukuthi ukulinganiselwa kwamadivayisi wokudlulisa kunganqotshwa ngezinhlobonhlobo zezesekelo ezitholakalayo kubadlulisi bengcindezi. (Isibonelo, ezinye izidlulisi zokushisa zinemishini yokusinxephezela yokushisa kanye nokulinganisa okuningiE isekethe ukukhulisa ukunemba kokufundwa kwabo.)
Njengoba izici eziningi zakha ukukhethwa kokudlulisa ingcindezi efanele, Ukutshala imali kumhlinzeki wezingcindezi ezisezingeni eliphakeme kungenye yezinqumo ezinhle kakhulu abathengi abangazenza. Kufanele ugxile ekutholeni umhlinzeki odumile onikeza uhlu olubanzi lokuzwa ingcindezi / imikhiqizo yokulawula kanye / noma izinsizakalo (e .. g. Izinsizakalo zokubuyisa kabusha.) Ukusebenza nomhlinzeki wekhwalithi kuzoqinisekisa ukuthi ukwazi ukukhulisa usizo nokusebenza kokudlulisa ingcindezi yakho isicelo sakho esithile.
