2. Ihame rya slide valve ihindura compressor ya screw
Agace kanyerera gakoreshwa mukugenzura intambwe idafite ubushobozi.Mugihe cyo gutangira bisanzwe, iki gice ntabwo kiremerewe.Agace kanyerera kayoborwa na micye igenzura binyuze mumavuta ya peteroli, amaherezo igahindura ubushobozi bwakazi bwa compressor.
Ubushobozi bwo guhinduranya slide valve nikintu cyubatswe gikoreshwa muguhindura amajwi muri compressor ya screw.Nubwo hariho uburyo bwinshi bwo guhindura amajwi ya compressor ya screw, uburyo bwo guhindura ukoresheje slide valve bwakoreshejwe cyane, cyane cyane mugutera inshinge.Gukonjesha amavuta hamwe na compressor zitunganijwe zirazwi cyane.Nkuko bigaragara ku gishushanyo cya 1, ubu buryo bwo guhindura ni ugushiraho valve yoguhindura slide kumubiri wa screw compressor hanyuma ugahinduka igice cyumubiri wa compressor.Iherereye mu masangano yinziga ebyiri zimbere kuruhande rwumuvuduko ukabije wumubiri kandi irashobora kugenda ninyuma mucyerekezo kibangikanye na silindiri.
Ihame rya slide valve kugirango uhindure umuvuduko wikigereranyo cya flux compressor ya screw ishingiye kubikorwa byakazi biranga compressor ya screw.Muri compressor ya screw, nkuko rotor izunguruka, umuvuduko wa gaze ya compression igenda yiyongera buhoro buhoro ukurikije umurongo wa rotor.Kubireba umwanya uhagaze, bigenda buhoro buhoro biva kumpera ya compressor kugeza kumpera.Nyuma yumuvuduko ukabije wumubiri ufunguye, mugihe rotor ebyiri zitangiye gushya no kugerageza kongera umuvuduko wa gaze, gaze zimwe zizanyura mumfunguzo.Ikigaragara ni uko ingano ya gaze yarenganye ifitanye isano n'uburebure bwo gufungura.Iyo umurongo wo guhuza wimukiye kumpera yo gufungura, gaze isigaye irafunzwe rwose, kandi inzira yo kwikuramo imbere itangira kuriyi ngingo.Imirimo ikorwa na compressor ya screw kuri gaze ya bypass kuva ifungura ikoreshwa gusa kugirango isohore.Kubwibyo, gukoresha ingufu za compressor ahanini ni igiteranyo cyimirimo yakozwe yo guhagarika gaze yarangije gusohoka hamwe nakazi ko guteranya imashini.Kubwibyo, mugihe ubushobozi bwo guhinduranya slide valve ikoreshwa muguhindura umuvuduko wa volumetric umuvuduko wa compressor ya screw, compressor irashobora gukomeza gukora neza murwego rwo guhinduka.
Muri compressor nyirizina, muri rusange ntabwo ari umwobo mu kabati, ahubwo ni imiterere.Igice cya slide kigenda mumashanyarazi munsi ya rotor kandi ikwemerera guhora uhindura ubunini bwifungura.Gazi isohoka mu gufungura izasubira ku cyambu cya compressor.Kubera ko compressor mu byukuri idakora kuri iki gice cya gaze, ubushyuhe bwayo ntibwiyongera, ntabwo rero bukeneye gukonjeshwa mbere yuko bugera kuri gazi nyamukuru ku cyambu..
Igice cya slide kirashobora kugenda mubyerekezo byose ukurikije ibisabwa na sisitemu yo kugenzura.Hariho inzira nyinshi zo kuyitwara.Uburyo busanzwe ni ugukoresha silindiri ya hydraulic, kandi sisitemu yamavuta ya compressor ya screw ubwayo itanga umuvuduko wamavuta asabwa.Mu mashini nkeya, slide valve itwarwa na moteri yagabanutse.
Mubyukuri, igituba kigomba kuba kingana na rotor.Mu buryo busa nabwo, intera isabwa kugirango slide yimuke ive mumitwaro yuzuye ijya mumuzigo wubusa igomba kuba imwe na rotor, kandi silindiri hydraulic nayo igomba kugira uburebure bumwe.Nyamara, imyitozo yerekanye ko niyo uburebure bwa slide valve ari ngufi gato, ibintu byiza byo kugenzura birashobora kugerwaho.Ibi ni ukubera ko iyo gufungura bypass byafunguwe bwa mbere hafi yisura ya suction, ubuso bwayo ni buto cyane, umuvuduko wa gaze ni muto cyane muriki gihe, kandi umwanya ufata kugirango rotor amenyo amenyo akure mu gufungura nayo ni ngufi cyane, bityo hazabaho umubare muto gusa wa gaze isohoka.Kubwibyo, uburebure nyabwo bwa slide valve irashobora kugabanuka kugera kuri 70% yuburebure bwigice cya rotor ikora, naho igice gisigaye kigakorwa neza, bityo bikagabanya ubunini rusange bwa compressor.
Ibiranga ubushobozi bwo guhinduranya slide valve bizatandukana na diameter ya rotor.Ni ukubera ko ubuso bwicyambu cya bypass buterwa no kugenda kwa valve ya slide iringaniza na kare ya diameter ya rotor, mugihe ingano ya gaze mucyumba cyo guhunika ihwanye na diameter ya rotor.Kugereranya na cube ya.Birakwiye ko tumenya ko iyo compressor ihagaritse gaze, nayo yongera umuvuduko wamavuta yatewe, amaherezo ikayirekura hamwe na gaze.Kugirango amavuta asohore ubudahwema, ingano runaka igomba kubikwa.Bitabaye ibyo, mugihe rwose nta mutwaro urimo, amavuta azegeranya mucyumba cyo guhunika, bigatuma compressor yo mu kirere idashobora gukomeza gukora.Kugirango amavuta asohore ubudahwema, mubisanzwe umuvuduko wikigereranyo cya byibuze 10%.Rimwe na rimwe, umuvuduko wa volumetricike ya compressor igomba kuba zeru.Muri iki gihe, umuyoboro wa bypass usanzwe utunganijwe hagati yo guswera no gusohora.Iyo umutwaro wuzuye wa zeru usabwa, umuyoboro wa bypass urakingurwa kugirango uhuze amasoko n'umuriro..
Mugihe ukoresheje ubushobozi bwo guhinduranya slide valve kugirango uhindure umuvuduko wa volumetricike ya compressor ya screw, ibintu byiza ni ugukomeza igipimo cyimbere cyimbere kimwe nuburemere bwuzuye mugihe cyo guhindura.Ariko, biragaragara ko iyo slide valve yimutse kandi umuvuduko wa volumetric umuvuduko wa compressor uba muto, uburebure bukora bwakazi bwa screw buba buto kandi igihe cyibikorwa byo kwikuramo imbere nacyo kiba gito, bityo igipimo cyumuvuduko wimbere kigomba kuba yagabanutse.
Mu gishushanyo nyirizina, icyerekezo cya slide gifite umwobo wa radiyo isohoka, igenda yerekeza hamwe na slide valve.Muri ubu buryo, kuruhande rumwe, uburebure bukomeye bwa rotor ya mashini ya rotor iragabanuka, kurundi ruhande, orifice ya radiyo isohoka nayo iragabanuka, kugirango wongere igihe cyo kwikuramo imbere kandi wongere igipimo cyo kwikuramo imbere.Iyo imishwarara ya radiyo yumurongo kuri slide valve hamwe na orifice ya axial isohoka ku gipfukisho cyanyuma ikozwe mubice bitandukanye byumuvuduko wimbere, igipimo cyumuvuduko wimbere gishobora gukomeza kuba kimwe nuburemere bwuzuye mugihe cyo guhindura ibintu murwego runaka .Kimwe.
Iyo ingano yoguhindura amajwi ya valve ikoreshwa muguhindura icyarimwe ingano ya radiyo yumuriro wa orifice ya mashini ya screw hamwe nuburebure bwakazi bukora bwa rotor, isano iri hagati yo gukoresha ingufu za mashini ya screw nigipimo cyijwi kiri mubitemba igipimo cyo guhindura 100-50%.Imbaraga zikoreshwa ziragabanuka hafi ugereranije no kugabanuka k'umubyigano wa volumetric, byerekana ubukungu bwiza bwo kugenzura ibicuruzwa bya slide.Birakwiye ko tumenya ko mugice cyanyuma cyurugendo rwa slide valve, igipimo cyumuvuduko wimbere kizakomeza kugabanuka kugeza igihe kigabanijwe kugeza kuri 1. Ibi bituma ingufu zikoreshwa ningufu zingana mugihe iki gihe gitandukana kurwego runaka ugereranije nu ibintu byiza.Ubunini bwo gutandukana biterwa nigipimo cyumuvuduko wimbere wimashini ya screw.Niba umuvuduko wo hanze ugenwa nuburyo ibintu bigenda ni muto, gukoresha ingufu zidafite imizigo ya mashini ya screw irashobora kuba 20% gusa muribyo byuzuye, mugihe mugihe igitutu cyo hanze ari kinini, gishobora kugera kuri 35%.Birashobora kugaragara kuva hano ko inyungu ikomeye yo gukoresha ubushobozi bwa slide valve ari uko imbaraga zo gutangira imashini ya screw ari nto cyane.
Iyo igenamigambi rya slide valve ikoreshwa, hejuru yubuso bwa slide ikora nkigice cya silinderi ya screw compressor.Hano hari orifice yuzuye kuri slide valve, kandi igice cyayo cyo hepfo nacyo kiyobora icyerekezo cya axial, bityo ibisabwa kugirango imashini ikorwe ni ndende cyane., bizatuma ibiciro byinganda byiyongera.Cyane cyane muri compressor ntoya, igiciro cyo gutunganya slide valve izabarirwa mugice kinini.Mubyongeyeho, kugirango tumenye neza imikorere yimashini ya screw, ikinyuranyo kiri hagati ya slide valve na rotor mubisanzwe ni kinini kuruta icyuho kiri hagati yumwobo wa silinderi na rotor.Mumashini ntoya, iyi ntera yiyongereye nayo izagira ingaruka kumikorere ya compressor.Kugabanuka gukabije.Kugirango tuneshe ibitagenda neza hejuru, mugushushanya imashini ntoya, ibikoresho byinshi byoroheje kandi bidahenze bigenga slide valve nabyo birashobora gukoreshwa.
Igishushanyo cyoroshye cya valve cyashushanyijeho umwobo wa bypass kurukuta rwa silinderi ihuye nuburyo bwa rotorike ya rotor, bigatuma gaze ishobora kuva muri ibyo byobo iyo bidapfunditswe.Igikoresho cya slide ikoreshwa ni "rotary valve" hamwe numubiri wizunguruka.Iyo izunguruka, irashobora gupfuka cyangwa gufungura umwobo wa bypass uhujwe nicyumba cyo guhunika.Kubera ko slide valve ikenera gusa kuzunguruka muriki gihe, uburebure rusange bwa compressor burashobora kugabanuka cyane.Igishushanyo mbonera kirashobora gutanga neza guhoraho ubushobozi.Ariko, kubera ko ingano yumwobo usohoka idahindutse, igipimo cyumuvuduko wimbere kizagabanuka mugihe gupakurura bitangiye.Muri icyo gihe, kubera ko hariho umwobo wa bypass ku rukuta rwa silinderi, hashyizweho umubare munini wa “clearance volume”.Gazi iri muri ino njwi izajya ihura nogusenyuka no kwaguka, bigatuma kugabanuka kwa volumetric na adiabatic bikora neza.
3. Inzira yo guhindura valve ya slide compressor
Kwimura slide valve ibumoso niburyo, ingano nziza yo kwikuramo iriyongera cyangwa igabanuka, kandi ingano yo gutanga gaze irahindurwa.Iyo gupakira: piston yimukira ibumoso na valve ya slide igenda ibumoso kandi gaze itanga gazi iriyongera;iyo gupakurura: piston yimuka iburyo na valve ya slide igenda iburyo kandi itangwa rya gaze rigabanuka.
4. Ibyifuzo byo gukoresha screw compressor slide valve ihinduka
Mubisanzwe, compressor zitagira amavuta ntizikoresha igikoresho cyo guhindura ubushobozi kugirango uhindure slide.Ibi ni ukubera ko icyumba cyo guhunika cyubwoko bwa compressor kitarimo amavuta gusa ahubwo nubushyuhe bwo hejuru.Ibi bituma ikoreshwa ryibikoresho bya slide valve bigorana tekiniki.
Mumavuta yinjizwamo amavuta ya compressor yindege, kubera ko uburyo bwo guhunika buguma budahindutse kandi imikorere yimikorere ikaba yarashizweho, igikoresho cyo guhindura ubushobozi bwa slide valve ntabwo gikoreshwa.Moteri ihindagurika ya moteri ikoreshwa muburyo bwo gukora compressor imiterere yoroshye ishoboka kandi ihuza nibikenewe kubyara umusaruro..
Birakwiye ko twerekana ko kubera igikoresho cyo guhindura ubushobozi gihindura slide valve, compressor irashobora gukomeza gukora neza mugihe cyimikorere ikora.Mu myaka yashize, ibikoresho byo guhindura ubushobozi byakoreshejwe no muri compressor zitagira amavuta hamwe na compressor yo mu kirere yatewe amavuta.Guhindura imyumvire ya slide valve.
