Ukwahlulahlulahlulahlulwa kwe-gaugsI-heater yokufudumeza kweoyile, Ukukhetha idrafti yedrafti kunye nofakelo kunye nokugcinwa kwemihla ngemihla koxinzelelo.
I-1 yokuhlelwa kwe-gaugs
I-Gagues Gagues inokuthi ihlulwe ngokwamanqanaba amane ngokwemigaqo yabo yokuguqula:
Uhlobo lokuqala yi-manometer yolwelo:
Ngokomgaqo-siseko we-hydrostatics, uxinzelelo olulinganisiweyo lubonakaliswa kukuphakama kwekholam yolwelo. Ifomu yesakhiwo ikwahlukile, ukuze ihlulwe ibe yi-gebe yoxinzelelo lwe-tube, ye-tube enye ye-tube kunye nokunye. Olu hlobo lwe-manometer lunokufumaneka ngokulula kwaye lubalulekile kakhulu ekusetyenzisweni, kodwa ukuchaneka kwayo kuya kuchaphazeleka kakhulu ngezinto ezinje ngesenzo se-capillary tubes, uxinano kunye neParallax. Kuba uluhlu lomlinganiso lumxinwa, lusetyenziswa ngokubanzi ukulinganisa uxinzelelo olusezantsi, umahluko woxinzelelo okanye isidanga sokuphumla.
Uhlobo lwesibini yimali ye-elate:
Iguqulwa kwingcinezelo elinganiswe ngokufuduka kwento engekhoyo yento ephosakeleyo ye-hlcthoti, njengeManometer yeTube yasentwasahlobo kunye ne-Manometer yeTube.
Uhlobo lwesithathu luphawu lombane:
Sisixhobo esiguqula uxinzelelo olulinganayo kwinani lombane kunye nezinto zombane (ezinje nge-voltage, efana ne-voltancy, efana nokuhanjiswa koxinzelelo.
Uhlobo lwesine sisixhobo se-piston soxinzelelo:
Ilinganiswe ngokusebenzisa umgaqo-siseko we-hydraulic cofa uxinzelelo loxinzelelo lwamanzi, kwaye uthelekise ubunzima bekhowudi elungeleleneyo besilika yongezwa kwi-piston ngoxinzelelo olulinganayo. Inemilinganiselo ephezulu yokulinganisa, incinci njenge-0.05 yamathumbu e-0.05 ~ 0? Impazamo ye-2%. Kodwa ixabiso libiza kakhulu, ulwakhiwo lunzima ngakumbi. Ukujonga ezinye iintlobo zokucinezelwa kwexesha ziyafumaneka njengesixhobo sokulinganisa esifanelekileyo.
Inkqubo yeoyile eshushu isetyenziswa kwi-Gephar yoTyhilo ngokubanzi, inezinto ezibuthathaka ityhubhu ye-bourddon Tube, ityhubhu ye-cube ivele, kwaye ityhubhu ye-cube idluliselwe ukuhambisa uxinzelelo ukubonisa uxinzelelo.
Therefore, the pressure gauge used in the thermal oil furnace system is the second elastic pressure gauge.
I-2 yokukhethwa kwegeji yoxinzelelo
Xa uxinzelelo lwe-Boiler lungaphantsi kwe-2,5 mi, ukuchaneka kwe-gege yoxinzelelo kungaphantsi kwe-2,5 yenqanaba: I-SMPA, ukuchaneka kwenqanaba loxinzelelo kungaphantsi kwe-1.5 inqanaba; Kwisiza soxinzelelo lokusebenza ngaphezu kwe-14MPA, ukuchaneka kwe-Gaugest kufuneka ibe yi-1,7MPA ye-GAURE ye-oyile kufuneka ibe yi-1.5MPA yoxinzelelo lwe-1,5 ukuya kwi-3 ephezulu yexabiso le-2. Ke ngenxa yokuhlola igeji inani liyi-700.
I-gauge yoxinzelelo ilungiselelwe izindlu ze-Boiler, ukuze kungabikho lula ukujonga, kodwa kulula ukwenza imisebenzi yokutyibilika rhoqo kwaye itshintshe imeko yegeji yoxinzelelo.
3. Ufakelo kunye nolondolozo lwemihla ngemihla loxinzelelo lwe-Irrmage
. Ukuba uxinzelelo lwe-gauge uphakamisa kubushushu obuqhelekileyo bokusebenzisa, iqondo lobushushu Impazamo eyongezelelweyo kufuneka ibandakanywe.
. Xa ufaka, ibhlokhi ukuvula isiqhushumbisi ngasemva kwetyala ukuze ungachaphazeli ukusebenza kwesiqhulo.
. Kwezi meko zimbini zoxinzelelo, umlinganiso osezantsi wegeji enkulu yoxinzelelo mayingaphantsi kwe-1/3 yomda ophantsi, kwaye icandelo le-vacuum lonke lisetyenziswa xa kulinganiselwe vacuum.
.
(5) Isixhobo kufuneka sikuphephe ukuntywila kunye nokungqubana ukuthintela ukonakala.
Ukuba unayo nayiphi na imibuzo malunga ne-I-Irmal ye-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-I-IOTI YOOLONGE, ncedaQhagamshelana nathi.
IXESHA LOKUQALA: Jun-27 ukuya ku-4024
