Ukuhlukaniswa kwezilinganiso zokucindezela ngaphakathii-heater kagesi yokushisa amafutha, ukukhethwa kwezikali zokucindezela nokufakwa nokugcinwa kwansuku zonke kwamageji okucindezela.
1 Ukuhlukaniswa kwamageji okucindezela
Izikali zokucindezela zingahlukaniswa zibe izigaba ezine ngokuya ngemigomo yazo yokuguqula:
Uhlobo lokuqala luyi-manometer yekholomu ye-liquid:
Ngokomgomo we-hydrostatics, ingcindezi elinganisiwe iboniswa ukuphakama kwekholomu ye-liquid. Ifomu lesakhiwo nalo lihlukile, ngakho-ke lingahlukaniswa libe yi-U-shaped tube gauge gauge, i-tube eyodwa ye-pressure gauge nokunye. Lolu hlobo lwe-manometer lunesakhiwo esilula futhi kulula kakhulu ukusisebenzisa, kodwa ukunemba kwalo kuzothinteka kakhulu yizici ezifana nesenzo samashubhu e-capillary, ukuminyana kanye ne-parallax. Ngenxa yokuthi ububanzi bokulinganisa buncane kakhulu, ngokuvamile busetshenziselwa ukukala ingcindezi ephansi, umehluko wengcindezi noma i-vacuum degree.
Uhlobo lwesibili luyi-elastic manometer:
Iguqulwa ibe yingcindezi elinganisiwe ngokugudluzwa kwe-deformation ye-element elastic, njenge-spring tube manometer kanye ne-manometer yemodi kanye ne-spring tube manometer.
Uhlobo lwesithathu igeji yomfutho kagesi:
Yithuluzi eliguqula ingcindezi elinganisiwe ibe yinani likagesi lezingxenye zikagesi (ezifana ne-voltage, i-current, frequency, njll.) ukuze kukale, njengama-transmitter okucindezela ahlukahlukene nezinzwa zokucindezela.
Uhlobo lwesine i-piston pressure gauge:
Kukalwa kusetshenziswa umgomo we-hydraulic press liquid transfer pressure, futhi kuqhathaniswe nenqwaba yekhodi ye-silicon elinganiselayo engezwe ku-piston nengcindezi elinganisiwe. Inokunemba kwesilinganiso esiphakeme, kuncane njengo-0.05 amathumbu ~ 0? Iphutha elingu-2%. Kodwa intengo ibiza kakhulu, isakhiwo siyinkimbinkimbi. Ukuhlola ezinye izinhlobo zamawashi okucindezela ayatholakala njengezisetshenziswa ezijwayelekile zokulinganisa ingcindezi.
Isistimu kawoyela oshisayo isetshenziswa kugeji yengcindezi evamile, inesici esibucayi ishubhu le-bourdon, itafula elingaphakathi kokunyakaza komshini wokuguqula, lapho kukhiqizwa ingcindezi, ishubhu yeBourdon izoba yi-elastic deformation, ukunyakaza komshini ukuya. guqula ukwakheka kwe-elastic kube ukunyakaza okujikelezayo, futhi isikhombisi esixhunywe kumshini sizoncishiswa ukukhombisa ingcindezi.
Ngakho-ke, i-gauge yokucindezela esetshenziswa ohlelweni lwesithando somlilo esishisayo iyigeji yesibili yokucindezela okunwebekayo.
2 Ukukhethwa kwegeji yokucindezela
Lapho ingcindezi ye-boiler ingaphansi kwama-2.5 mi, ukunemba kwesilinganiso sokucindezela akukho ngaphansi kwezinga le-2.5: ingcindezi yokusebenza ye-boiler ingaphezu kuka-2. I-SMPa, ukunemba kwegeji yokucindezela ayikho ngaphansi kwezinga le-1.5 ; Kuma-boilers anengcindezi yokusebenza enkulu kune-14MPa, ukunemba kwegeji yokucindezela kufanele kube yizinga 1. Ukucindezela kokusebenza komklamo wesistimu yamafutha ashisayo yi-0.7MPa, ngakho-ke ukunemba kwegeji yokucindezela esetshenzisiwe akufanele kucindezeleke i-2.5 grade 2 Ngoba i ububanzi begeji yokucindezela kufanele kube izikhathi ezingu-1.5 kuya kwezingu-3 ukucindezela okukhulu kwe-boiler, sithatha inani eliphakathi izikhathi ezingu-2. Ngakho-ke ku-gauge ye-pressure isamba singama-700.
I-gauge ye-pressure igxiliwe ku-boiler yezindlu, ukuze kungabi lula nje ukubuka, kodwa futhi kube lula ukwenza imisebenzi evamile yokuhlanza nokushintsha indawo ye-gauge ye-pressure gauge.
3. Ukufakwa nokugcinwa kwansuku zonke kwesilinganiso sokucindezela kwesithando somlilo esishisayo
(l) Izinga lokushisa elizungezile legeji yokucindezela lingu-40 kuya ku-70 ° C, futhi umswakama ohlobene awukho ngaphezu kuka-80%. Uma igeji yokucindezela ichezuka ekushiseni okuvamile kokusetshenziswa, iphutha elengeziwe lokushisa kufanele lifakwe.
(2) I-gauge yokucindezela kufanele ime mpo, futhi ilwele ukugcina izinga elifanayo nephuzu lokulinganisa, njengokuthi umehluko uphezulu kakhulu kwiphutha elengeziwe elibangelwa ikholomu yoketshezi, ukukalwa kwegesi akukwazi ukucatshangelwa. Lapho ufaka, vimba ukuvuleka okungaqhume ngemuva kwekesi ukuze ungaphazamisi ukusebenza kokuvikela ukuqhuma.
(3) Ububanzi bokulinganisa bokusetshenziswa okuvamile kwegeji yokucindezela: hhayi ngaphezu kwe-3/4 yomkhawulo ongaphezulu wokulinganisa ngaphansi kwengcindezi ye-static, futhi hhayi ngaphezu kwe-2/3 yomkhawulo ongaphezulu wokulinganisa ngaphansi kokuguquguquka. Kulezi zimo ezimbili ezingenhla zengcindezi, ukulinganisa okuncane kwegeji yokucindezela okukhulu akufanele kube ngaphansi kuka-1/3 womkhawulo ophansi, futhi ingxenye ye-vacuum isetshenziswa yonke lapho kukalwa i-vacuum.
(4) Uma usebenzisa, uma i-press gauge pointer yehluleka noma izingxenye zangaphakathi zixega futhi zingakwazi ukusebenza ngendlela evamile, kufanele ilungiswe, noma uxhumane nomkhiqizi ukuze uyilungise.
(5) Ithuluzi kufanele ligweme ukudlidliza nokushayisana ukuze kugwenywe umonakalo.
Uma unemibuzo mayelana nesithando somlilo esishisayo sikagesi, sicelaXhumana nathi.
