Ebunjiniyela bemaphayiphi, kukhetsa lokufanele kwemavalvu agezi kungenye yetimo tesicinisekiso sekuhlangabetana netidzingo tekusebentisa. Uma ivalvu kagesi lesetjentisiwe ingakhetfwa kahle, angeke ithinte kusetjentiswa kuphela, kepha futsi iletse imiphumela lemibi noma kulahlekelwa lokukhulu, ngako-ke, kukhetsa lokufanele kwemavalvu agezi ekwakhiweni kwebunjiniyela bemaphayiphi.
Indzawo yekusebenta yevalve kagesi
Ngaphezu kwekunaka imikhawulo yephayiphi, kunakwa lokukhetsekile kufanele kukhokhelwe timo temvelo tekusebenta kwayo, ngoba idivayisi kagesi ku-valve kagesi yimishini ye-electromechanical, futsi simo sayo sekusebenta sitsintseka kakhulu yimvelo yayo yekusebenta. Kuvamile, imvelo yekusebenta valve kagesi ngalendlela lelandzelako:
1. Kufakwa ngekhatsi endlini noma kusetjentiswa ngaphandle ngetindlela tekuvikela;
2. Kufakwa ngaphandle emoyeni lovulekile, ngemoya, sihlabatsi, imvula kanye nematolo, kukhanya kwelilanga kanye nalokunye lokugugulekako;
3. Inendzawo levutsako noma igesi leqhumako noma lutfuli;
4. Indzawo leshisako lenemanti, leyomile;
5. Lizinga lekushisa lendzawo lesemkhatsini wemaphayiphi liphakeme nga 480°C noma ngetulu;
6. Lizinga lekushisa lelikhona lingaphansi kwa -20°C;
7. Kulula kukhukhulwa nobe kucwiliswa emantini;
8. Tindzawo letinetintfo letikhipha imisebe (tikhungo temandla enuzi kanye netintfo tekuhlola tintfo letikhipha imisebe);
9. Indzawo yemkhumbi noma idokodo (ngekufafata luswayi, sikhunta, kanye nemswakama);
10. Tikhatsi letinekudvudvuta lokukhulu;
11. Tikhatsi letivame kuba nemlilo;
Kumavalvu agezi kuletindzawo letishiwo ngenhla, sakhiwo, tintfo kanye netinyatselo tekuvikela tetintfo tagezi tehlukile. Ngakho-ke, idivayisi kagesi valve ehambisanayo kufanele ukhethwe ngekuya kwesimo sekusebenta lesishiwo ngenhla.
Tidzingo tekusebenta tageziemavalvu
Ngekuya kwetidzingo tekulawula tebunjiniyela, ngevalve kagesi, umsebenti wekulawula ugcwaliswa yidivayisi kagesi. Inhloso yekusebentisa emavalvu agezi kutsi kufezekiswe kulawula kwagezi lokungekho ngesandla noma kulawula kwekhompyutha kwekuvula, kuvala kanye nekulungisa kuhlanganiswa kwemavalvu. Tintfo tagezi talamuhla atisetjentiselwa nje kuphela kusindza emandla ebantfu. Ngenca yemehluko lomkhulu emsebentini kanye nelizinga lemikhicito levela kubakhiciti labehlukene, kukhetsa tintfo tagezi kanye nekukhetsa emavalvu kubaluleke ngendlela lefanako kulephrojekthi.
Kulawula kwagezi kwageziemavalvu
Ngenca yekutfutfuka lokuchubekako kwetidzingo tekusebenta ngekuzenzakalela kwetimboni, ngakulolunye luhlangotsi, kusetjentiswa kwemavalvu agezi kuyakhula, futsi ngakulolunye luhlangotsi, tidzingo tekulawula emavalvu agezi tiyakhula futsi tiyinkimbinkimbi. Ngakho-ke, umklamo emavalvu kagesi ngekwekulawula kagesi nako njalo kuvuselelwa. Ngekuchubeka kwesayensi netebucwepheshe kanye nekutsandvwa kanye nekusetjentiswa kwemakhompyutha, tindlela letinsha naletehlukahlukene tekulawula gezi titawuchubeka tivela. Kute kulawulwe konkhe kwagezi .ivalvu, kunakwa kufanele kukhokhelwe kukhetsa imodi yekulawula valve kagesi. Sibonelo, ngekuya kwetidzingo tephrojekthi, noma ngabe kusetjentiswa imodi yekulawula lesemkhatsini, noma imodi yekulawula yinye, noma ngabe kuxhumana naletinye tintfo tekusebenta, kulawula luhlelo noma kusetjentiswa kwekulawula luhlelo lwekhompyutha, njll, simiso sekulawula sehlukile. Isampula yemkhiciti wetintfo tagezi tevalve iniketa kuphela simiso sekulawula gezi lesijwayelekile, ngako-ke litiko lekusebentisa kufanele lente kuveta kwebuchwepheshe nemkhiciti wetintfo tagezi bese ucacisa tidzingo tebuchwepheshe. Ngetulu kwaloko, nawukhetsa i-valve kagesi, kufanele ucabange kutsi ungatsenga yini umlawuli we-valve kagesi lowengetiwe. Ngoba jikelele, umlawuli kudingeka kutsengwa ngekwehlukana. Etimeni letinyenti, uma usebentisa kulawula lokukodwa, kuyadzingeka kutsi uthenge umlawuli, ngoba kulula futsi kushiphile kutsenga umlawuli kunekutsi uklanye futsi ukhicite ngumsebentisi. Lapho kusebenta kwekulawula kagesi kungakhoni kuhlangabetana netidzingo tekuklama kwebunjiniyela, umkhiciti kufanele aphakanyiswe kutsi agucule noma aklanye kabusha.
Ledivayisi legezi yevalve yidivayisi lebona kuhlelwa kwevalvi, kulawula lokuzenzakalelayo kanye nekulawula lokukhashane *, futsi inchubo yayo yekunyakata ingalawulwa linani lekushaya, i-torque noma i-axial thrust. Njengobe timphawu tekusebenta kanye nelizinga lekusetjentiswa kwe-valve actuator kuya ngeluhlobo lwe-valve, kucaciswa lokusebenta kwedivayisi, kanye nesikhundla se-valve kuphayiphi noma imishini, kukhetsa lokufanele kwe-valve actuator kubalulekile kuvimbela kulayishwa kakhulu (i-torque lesebentako iphakeme kune-torque yekulawula). Ngalokuvamile, isisekelo sekukhetsa lokufanele kwetintfo tagezi tevalve kunjalo:
I-torque yekusebentaI-torque yekusebenta yipharamitha leyinhloko yekukhetsa idivayisi kagesi ye-valve, futsi i-torque yekukhipha idivayisi kagesi kufanele ibe tikhatsi letingu-1.2 ~ 1.5 te-torque yekusebenta ye-valve.
Kukhona takhiwo letimbili letiyinhloko temshini tekusebenta idivayisi kagesi ye-valve yekucindzetela: munye akahlonyiswa nge-disc yekucindzetela futsi ukhipha ngco i-torque; Lomunye kutsi ulungiselelwe ipuleti lekucindzetela, bese i-torque lephumako iguculwa ibe yi-thrust lephumako nge-nati yesicu epuletini lekucindzetela.
Inani lekujika lokujikeletako kweshaft yekukhipha yevalve yedivayisi kagesi lihlobene nebubanti lobubitwako bevalve, umsindvo wesicu kanye nenani lemicu, lekufanele ibalwe ngekuya kwe M = H / ZS (M linani leliphelele lekujika kwe valve kutsi idivayisi kagesi kufanele ihlangabetane nayo, S he yi the pitch of the kudluliswa kwesicu sevalve, futsi Z linani letinhloko letinetintsambo te .ivalvulutsi).
Uma umkhawulo lomkhulu wesicu lovunyelwe yintfo legezi ungakhoni kudlula esicu sevalve lefakwe, angeke uhlanganiswe ube yivalve legezi. Ngakho-ke, ububanzi bangaphakathi shaft lokukhipha imbobo actuator kumele kube mkhulu kunebubanti bangaphandle sicu valve induku evulekile. Ku-valve yendvuku lemnyama ku-valve lejikeletako leyingcenye kanye ne-valve lejikako leminyenti, noma inkinga yekudlula yebubanti besicu sevalve ayicatshangelwa, bubanti besicu sevalve kanye nebukhulu be-keyway kufanele buphindze bucatshangelwe ngalokugcwele uma kukhetsa, kute kutsi kusebente ngendlela lejwayelekile ngemuva kwekuhlanganiswa.
Uma sivinini sekuvula nekuvala sevalve yesivinini sekukhipha sishesha kakhulu, kulula kukhicita isando semanti. Ngakoke, sivinini lesifanele sekuvula nekuvala kumele sikhetfwe ngekuya kwetimo letehlukene tekusebentisa.
Valve actuators babe tidzingo tabo letikhetsekile, lokusho kutsi kumele bakhone kuchaza torque noma emandla axial. Ngalokuvamileivalvuema-actuators asebentisa tihlanganiso letinciphisa i-torque. Uma bukhulu bedivayisi kagesi kuncunywa, torque yayo yekulawula nayo inqunywa. Ngalokuvamile gijima ngesikhatsi lesibekiwe, injini ngeke ilayishwe kakhulu. Kepha, uma letimo letilandzelako tenteka, kungaholela ekulayisheni kakhulu: kwekucala, ivoltheji yekuniketa emandla iphansi, futsi i-torque ledzingekako ayikhoni kutfolakala, kute kutsi imoto iyekele kujikeleta; lesibili kutsi ngephutsa ulungise indlela yekunciphisa i-torque kute yente ibe nkulu kune-torque yekuma, lokuholela ekuchubekeni ne-torque lengetulu kwemkhawulo kanye nekumisa imoto; kwesitsatfu kusetjentiswa ngesikhatsi lesitsite, futsi kugcwala kwekushisa lokukhicitwako kwedlula linani lekukhuphuka kwekushisa lelivumelekile lemoto; Kwesine, umjikeleto wendlela yekunciphisa i-torque yehluleka ngesizatfu lesitsite, lokwenta kutsi i-torque ibe nkulu kakhulu; Kwesihlanu, lizinga lekushisa le-ambient liphakeme kakhulu, lokunciphisa umthamo wekushisa kwemoto.
Esikhathini esidlule, indlela yekuvikela imoto bekukusebentisa emafusi, ema-relays lasebenta kakhulu, ema-relays lashisako, ema-thermostat, njll, kepha letindlela tinetinzuzo tato kanye nebubi bato. Kute indlela yekuvikela letsembekile yemishini yemtfwalo logucukako njengetintfo tagezi. Ngako-ke, inhlanganisela lehlukahlukene kumele yamukelwe, lekungafingqwa ibe tinhlobo letimbili: munye kwehlulela kwandza noma kwehla input current motor; Kwesibili kutsi wehlulele simo lokushisa motor ngokwayo. Nganoma nguyiphi indlela, noma nguyiphi indlela icabanga umkhawulo wesikhatsi lesiniketwe semandla ekushisa kwemoto.
Ngalokuvamile, indlela lesisekelo yekuvikela yekulayisha kakhulu kutsi: kuvikela kulayisha kakhulu kusebenta lokuchubekako noma kusebenta kwekugijima kwemoto, kusetjentiswa i-thermostat; Kute kuvikelwa kwe-rotor yesitolo semoto, kudluliselwa lokushisako kuyamukelwa; Kuletingoti tekucitsa sikhatsi lesifishane, kusetjentiswa emafusi noma ema-relay lasebenta kakhulu.
Kuhlala lokucinile kakhuluemavalvu evivane,Ivalvu yesango, hlola ivalvuimininingwane, ungatsintsana natsi nge whatsapp nobe nge E-mail.
