Ivalve yesango lomoya elijikelezayo liyinxalenye ephambili yenkqubo yezinto. Ngokuqhelekileyo kuqwalaselwa ukuba ivalve yivalve nje enokusetyenziswa kulo naliphi na inani leenkqubo zokuphatha izinto ezahlukeneyo. Zonke iintlobo zeevalvu ziquka amacandelo asisiseko afanayo: i-valve body ene-inlet kunye ne-outlet, iipleyiti ezimbini zokuphela, kunye ne-rotor enamacangca. Ngexesha lokusebenza, i-shaft iqhutyelwa ukuba ijikelezwe yi-motor kunye nekhonkco. Xa i-blade ijikeleza, umthamo othile wezinto eziphathekayo ungena kwi-pocket ye-rotor nge-inlet ye-valve, uze uhambe uye kwi-valve outlet.
Ngokweempawu zezinto eziza kucutshungulwa, i-valve ineendlela ezahlukeneyo zokucwangciswa. Uninzi lwabavelisi babonelela ngeevalvu ezijikelezileyo, zesikwere okanye ezixande. Umzimba wevalvu udla ngokwenziwa ngentsimbi etyhidiweyo, i-aluminiyam okanye isinyithi esingenasici, kwaye unokuba nengubo ekhethekileyo yokwaleka kwiimveliso zokusila okanye ukugqiba okukhazimliswe kakhulu kushishino lokutya kunye nobisi. I-rotor inokuvulwa okanye ivalwe, kunye namaqabunga amathandathu ubuncinane, kwaye inokulungiswa ngamacwecwe, okanye isinyithi kunye neengcebiso eziguquguqukayo, kuxhomekeke kwisicelo. Iindidi zevalvu yesango lomoya elijikelezayo ziquka ukutyhutyha, ukuvuthela kunye nokungena ecaleni â????? Nganye ineenzuzo zayo kwaye ifanelekile kwizicelo ezahlukeneyo.
Ivalve yesango lomoya ejikelezayo yenzelwe ukusetyenziswa njengesitshixo somoya, isixhobo sokulinganisa iimitha, okanye zombini. Zenzelwe ukunciphisa ukuvuza komoya ngelixa zivumela izixhobo ukuba zidlule phakathi kwezixhobo ezahlukeneyo phantsi koxinzelelo olwahlukileyo. I-valve iphinda isebenze njengesixhobo sokulinganisa esiza kusebenza phantsi komthwalo wentloko yezinto eziphathekayo kunye nokulungelelanisa ukuhamba kwezinto kwizinga elifunekayo phakathi kwezixhobo ezinoxinzelelo olufanayo.
Nangona i-valve elula, zonke iinxalenye zichanekile ukuba zenze i-tight, i-gap encinci yokusebenza phakathi kwe-rotor kunye nezindlu. Oku kunyamezelwa okuqinileyo kudla ngokuba yi-0.004 ukuya kwi-0.006 intshi, nto leyo yi-avareji yobunzima beenwele zomntu. Zeziphi ezi zikhewu zincinci zidala "???? isitshixo somoya”???? Ngenxa yokuba banciphisa ukuvuza komoya phakathi kwendawo yokungena kunye ne-outlet flanges kwaye bavumela izinto ukuba zidlule kwivalve. Ukusuka kwinkqubo yokuqokelela uthuli ukuya kwi-vacuum receiver ukuya kwinkqubo yokuhambisa uxinzelelo lwe-dilution, i-valve yesango lomoya elijikelezayo livumela ukuhanjiswa kwezinto ezinokulahlekelwa komoya omncinci kwaye ivumela inkqubo ukuba iqhube ngokuqhubekayo.
Kweli nqaku, ndiya kugxininisa izizathu zokuvala i-airlock ye-rotary kunye nendlela yokuthintela, kwaye uxoxe ngeendlela zokuphatha iimveliso ezinamaqhekeza amakhulu (izinto ezinzima ezifana nezixhobo ze-fibrous okanye iiplastiki zeplastiki), apho imveliso icheba kwaye Iivalvu ezivaliweyo ziyingxaki enkulu.
Njengoko bekutshiwo ngaphambili, uninzi lweevalvu ze-airlock ezijikelezayo zinokunyamezela okungqongqo phakathi kwe-rotor kunye neqokobhe lomzimba wevalve, ke xa ujongana nothuli, umgubo kunye namasuntswana amancinci, imveliso idlula kwi-airlock yesiqhelo ejikelezayo ngaphandle kweengxaki. Ukucheba kunye nokuvala kwenzeka xa iinqununu ezinkulu, ezinzima zingeniswa kwaye zifakwe phakathi kwee-rotor blades ezijikelezayo njengoko zingena kwi-casing. Esi senzo sokucudisa sinokubangela ukungcangcazela, ukukhala, kunye neejam, kwaye kubangele umonakalo kwimveliso. Ukuvala kungenzeka kwakhona xa ubungakanani bevalvu buncinci kakhulu. Umzekelo, i-intshi ezi-3. Igaqa alinako ukudlula i-intshi ezi-6. I-valve, kuba ubunzima bukhulu kunobukhulu be-rotor cavity kwi-valve.
Ukuba ufumana i-jam yephepha ngexesha lokusebenza, nceda ubhekisele kwincwadana yokusebenza kunye nokugcinwa komenzi kwaye ukhangele iingxaki ezinjalo eziqhelekileyo. Nantsi eminye imibuzo onokuyibuza:
Kwakhona kunokwenzeka ukuba ukuphazamiseka kunokwenzeka kwiinyanga okanye iminyaka emva kokugunyaziswa. Ngaba kukho naluphi na utshintsho kwinkqubo-umzekelo ukufumana imathiriyeli evela kubaboneleli abahlukeneyo (enokuba neempawu ezahlukileyo ezifana nesiqulatho sokufuma) okanye ukuqala kwemozulu ebandayo yofakelo lwangaphandle? Ezinye izithintelo ezinokuthi zibekho ngenxa yezinto zangaphandle ezingena kule nkqubo, ezifana nezitshixo okanye iintsimbi ze-welding, okanye inkunkuma exutywe ngababoneleli.
Ngokuxhomekeke kwinkqubo yakho, kukho iindlela ezininzi zokunciphisa ingxaki enokubakho yokuvala ivalvu. Usebenzisa ivalve yemveli ethe tye, ungafaka incam yerubha ebhetyebhetye kwirotor ehlengahlengiswayo (efana nepolyurethane okanye iTeflon) kwizicelo zokuhambisa ngoomatshini, okanye ufakele isiphambukisi sokucheba esifakwe kwindawo yokungena yesitshixo somoya esijikelezayo ukwenza. Izinto eziphathekayo ukuphepha ukudibanisa phakathi kwee-rotor blades kunye ne-valve inlet. Enye inketho kukulinganisa imveliso kwisitshixo somoya esijikelezayo ukuze isingxobo sigcwaliswe ngokuyinxenye kuphela, ukuze i-airlock ejikelezayo icuthe ukuvuza komoya, kodwa ingasasebenzi njengesixhobo sokulinganisa. Â
Esona sisombululo silungileyo sokuthintela ukucheba kunye nokuvala kukutshixa umoya ojikelezayo osecaleni, olungiselelwe ngokukodwa ukoyisa le ngxaki yokucudisa, kwaye yenzelwe uxinzelelo olulungileyo kunye ne-vacuum / suction pneumatic transveying systems. Igama levalve livela kumqala wokungena, ongekho ngokupheleleyo kwiziko, okuvumela ukuba umkhiqizo ungene kwicala le-rotor endaweni ephezulu. Ngoyilo lwecala lokungena komqala, imveliso ibanjwe ngokunyuka kwee-rotor blades, ezigcina imveliso ingekho kwindawo yokucheba. Oku kunciphisa ukugcwaliswa kwepokotho, okunciphisa amathuba okucheba imveliso. Umqala wokungena nawo une?????V???? Ubume be-rotor obungena kwizindlu, ukunciphisa amanqaku e-pinch kunye nokunceda ukutyhala imveliso kude. Uyilo lwale valve lunciphisa amandla okucheba kwemveliso kwaye kunciphisa amathuba okuba nomthwalo wempembelelo, onokubangela umonakalo kumacandelo okuqhuba. Ivalve ilunge kakhulu kushishino lweplastiki, nokuba ilungisa amasuntswana eplastiki ekrwada okanye imathiriyeli esetyenzisiweyo kushishino lokurisayikilisha. Isenokusetyenziswa ukuphatha amasuntswana amakhulu, abuthathaka ukunciphisa uloyiko lokucheba kumonakalo wemveliso.
Ukuba unayo nayiphi na inkqubo exhalabisayo malunga nokuvaleka kwemveliso enokwenzeka, nceda uqhagamshelane nomvelisi wevalvu yakho ukuqinisekisa ukuba uyifakile ivalve yesango lomoya echanekileyo kwinkqubo yakho. Imibuzo eqhelekileyo ekufuneka bayibuze ibandakanya imveliso elungiswayo, ukuxinana kwesambuku, ukuhanjiswa kobungakanani bamasuntswana, ukuba ingaba imveliso ibuthathaka na, ubushushu obuphezulu, umahluko woxinzelelo, izinga lokukhupha, kunye noyilo lwenkqubo. Ngokuxhomekeke kwimveliso kunye nobungakanani bamasuntswana, iisampulu ezincinci zinokufuneka ukuze zivavanywe, okanye iisampulu ezinkulu zinokufuneka kuvavanyo. Ngolwazi oluchanekileyo lwesicelo, uhlobo lwevalvu, kunye nokukhetha koyilo, uninzi (ukuba asilulo lonke) ukuxinana, ukucheba, kunye neengxaki zengxolo zinokoyiswa.
