Screw air compressor ndi ma compressor abwino osamutsidwa, omwe amakwaniritsa cholinga cha kuponderezana kwa gasi kudzera pakuchepetsa pang'onopang'ono kuchuluka kwa ntchito.
Voliyumu yogwira ntchito ya screw air compressor imapangidwa ndi ma cogs a rotor omwe amayikidwa mofananirana wina ndi mnzake ndikulumikizana wina ndi mnzake ndi chiphaso chomwe chimakhala ndi ma rotors awa. amalowetsedwa m’zibowo za wina ndi mzake, ndipo pamene rotor ikuzungulira, mano olowetsedwa m’chiguduli cha winayo amasunthira ku mapeto a utsi, kotero kuti voliyumu yotsekeredwa ndi mano a mnzakeyo imachepa pang’onopang’ono, ndipo kupanikizika kumawonjezeka pang’onopang’ono mpaka mphamvu yofunikira ifike. Pamene kuthamanga kwafika, ma cogs amalumikizana ndi doko lotulutsa mpweya kuti akwaniritse utsi.
Pambuyo pa alveolar kulowetsedwa ndi mano a mdani omwe akugwira nawo ntchito, mipata iwiri yolekanitsidwa ndi mano imapangidwa. Alveolar pafupi ndi mapeto akuyamwitsa ndi voliyumu yoyamwa, ndipo yomwe ili pafupi ndi mapeto a mpweya ndi kuchuluka kwa mpweya woponderezedwa. kuti voliyumu yoyamwa ikupitiliza kukulirakulira ndipo kuchuluka kwa gasi wopanikizidwa kumapitilirabe kuchepa, potero kuzindikira njira yoyamwa ndi kuphatikizika mu cogging iliyonse. Pamene kupanikizika kwa gasi wa gasi woponderezedwa mu cogging kufika pa mphamvu yotulutsa mpweya wofunikira, kugwedeza kumangolankhulana ndi mpweya ndipo ndondomeko ya mpweya imayamba. amabwerezedwa, kotero kuti kompresa akhoza mosalekeza kupuma, compress ndi utsi.
Mfundo yogwirira ntchito ndi kapangidwe ka screw compressor:
1. Njira yoyamwitsa: Doko loyamwa lomwe lili kumbali yolowera pamtundu wa screw liyenera kupangidwa kuti chipinda chopondera chizikoka bwino. Mpweya wa compressor wamtundu wa screw ulibe gulu la valve yolowera komanso yotulutsa. Kudya kumangosinthidwa ndi kutsegula ndi kutseka kwa valve yolamulira. Pamene rotor ikuzungulira, danga la dzino la rotor lalikulu ndi lothandizira limasamutsidwa kumalo otsegulira khoma la mpweya, danga z * ndi lalikulu, panthawiyi malo a groove a rotor amalankhulana ndi mpweya waulere wa mpweya. polowera, chifukwa mpweya wonse wa m'mphepete mwa dzino umatulutsidwa panthawi yopuma, ndipo mphuno ya dzino imakhala yopanda phokoso kumapeto kwa kutulutsa. Akasamutsidwa kumalo olowera mpweya, danga z* ndi lalikulu. Panthawiyi, danga la dzino la rotor limalankhulana ndi mpweya waulere wa mpweya wolowera, chifukwa mpweya wonse wa m'mphepete mwa dzino umatulutsidwa panthawi yopuma. Pa kupwa kupwila, kino kyelekejo kidi na mvubu mpata. Ikasamutsidwa ku mpweya wolowera, mpweya wakunja umayamwa ndikulowa m'mphepete mwa dzino la ma rotors akuluakulu ndi othandizira. Mpweya wolowera mbali ya rotor umachotsedwa polowera mpweya wa chassis, ndipo mpweya pakati pa ma grooves amatsekedwa.
2. Kusindikiza ndi kutumiza njira: Kumapeto kwa kuyamwa kwa ma rotor akuluakulu ndi othandizira, mphuno ya dzino la ma rotor akuluakulu ndi othandizira ndi chassis amatsekedwa. Panthawiyi, mpweya umatsekedwa m'mphepete mwa dzino ndipo sutulukanso, ndiko kuti, [kusindikiza] .Ma rotor awiriwa akupitirizabe kusinthasintha, ndipo nsonga zawo za mano ndi nsonga za mano zimagwirizana kumapeto kwa kuyamwa, ndipo pamwamba pa anastomosis. pang'onopang'ono amapita ku mapeto a utsi.
3. Kuponderezedwa ndi jekeseni wamafuta: Panthawi yotumizira, ma meshing amasunthira pang'onopang'ono mpaka kumapeto kwa utsi, ndiko kuti, poyambira dzino pakati pa meshing pamwamba ndi doko lotulutsa mpweya limachepa pang'onopang'ono, ndipo mpweya womwe uli m'mphepete mwa dzino umakanizidwa pang'onopang'ono. ndipo kuthamanga kumawonjezeka. Iyi ndiyo [compress process].Panthawi yomweyi ngati kupanikizika, mafuta opaka mafuta amawapoperanso mu chipinda choponderezedwa ndikusakanikirana ndi mpweya wa chipinda chifukwa cha kusiyana kwapakati.
4. Njira yotulutsa mpweya: Pamene ma meshing mapeto a nkhope ya screw air kompresa yokonza rotor imasamutsidwa kuti ilumikizane ndi utsi wa chassis, (panthawiyi kupanikizika kwa gasi wopanikizidwa ndi z * mkulu) mpweya woponderezedwa umayamba kutulutsidwa. mpaka meshing pamwamba pa dzino pachimake ndi dzino groove anasamukira ku utsi mapeto nkhope. Panthawiyi, malo otsetsereka a dzino pakati pa meshing pamwamba pa ma rotor awiri ndi doko lotulutsa chassis ndi zero, ndiye kuti, (njira yotulutsa mpweya) yatha. Panthawi imodzimodziyo, kutalika kwa mphuno ya dzino pakati pa meshing pamwamba pa rotor ndi mpweya wolowetsa mpweya wa chassis umafika z * yaitali, ndipo njira yoyamwa ikuchitika.
Screw air compressors amagawidwa kukhala: mtundu wotseguka, mtundu wotsekedwa, mtundu wotsekedwa kwathunthu
1. Chotsekera bwino wononga kompresa: thupi limatenga mawonekedwe achitsulo apamwamba kwambiri, otsika-porosity okhala ndi mapindikidwe ang'onoang'ono amafuta; thupi limatenga kamangidwe ka khoma kawiri ndi ndime yotulutsa mpweya, mphamvu zambiri komanso zotsatira zabwino zochepetsera phokoso; mphamvu zamkati ndi zakunja za thupi ndizokhazikika, ndipo palibe chiopsezo chotsegula ndi theka-otsekeredwa kuthamanga kwakukulu; chipolopolocho ndi chitsulo chokhala ndi mphamvu zambiri, maonekedwe okongola komanso kulemera kwake. chonyamula m'munsi chimamizidwa mu thanki yamafuta, ndipo kunyamula kumayikidwa bwino; mphamvu ya axial ya rotor imachepetsedwa ndi 50% poyerekeza ndi mtundu wotsekedwa ndi wotseguka (kusinthasintha kwa shaft yamoto kumbali ya utsi); palibe chiopsezo yopingasa galimoto cantilever, mkulu kudalirika; pewani kukhudzidwa kwa screw rotor, spool valve, ndi kulemera kwa motor rotor pakulondola kofananira, ndikuwongolera kudalirika; ndondomeko yabwino ya msonkhano.Mapangidwe ozungulira a wononga opanda pampu ya mafuta amathandiza kuti kompresa kuthamanga kapena kuyima popanda kusowa kwa mafuta.Kutsika kwapansi kumamizidwa mu thanki yamafuta lonse, ndipo kumtunda kumatenga kuthamanga kwa kusiyana kwa mafuta; dongosolo osiyana kuthamanga zofunika ndi otsika. Pakachitika mwadzidzidzi, ntchito yoteteza mafuta otsekemera imapewa kusowa kwa mafuta opangira mafuta, zomwe zimathandiza kuti pakhale kutsegulidwa kwa unit panthawi yakusintha. zomwe zingapangitse kuti koyilo yamoto ipse mosavuta; kuwonjezera apo, kulephera sikungathetsedwe mu nthawi.
2. Semi-otsekeredwa screw kompresa
Utsi-utakhazikika injini, otsika kutentha ntchito galimoto, moyo wautali; kompresa yotseguka imagwiritsa ntchito mpweya kuziziritsa mota, kutentha kwa injini kumakwera, komwe kumakhudza moyo wagalimoto, komanso malo ogwirira ntchito a chipinda cha makompyuta ndi osauka; kugwiritsa ntchito utsi kuziziritsa galimotoyo, kutentha kwa galimoto ndi kwakukulu kwambiri, moyo wa galimoto ndi waufupi.Kawirikawiri, mafuta akunja ndi okulirapo, koma mphamvu zake ndizokwera kwambiri; mafuta omangika amaphatikizidwa ndi compressor, yomwe ndi yaying'ono kukula kwake, kotero zotsatira zake zimakhala zosauka.Mphamvu yachiwiri yolekanitsa mafuta imatha kufika 99.999%, yomwe ingathe kuonetsetsa kuti mafuta abwino a compressor apangidwe pansi pazikhalidwe zosiyanasiyana zogwirira ntchito. Plunger semi-enclosed screw compressor imayendetsedwa ndi giya kuti iwonjeze liwiro, liwiro limakhala lalitali (pafupifupi 12,000 rpm), kuvala ndikwambiri, ndipo kudalirika kwake ndi koyipa.
Chachitatu, tsegulani screw compressor
Ubwino wa mayunitsi otseguka ndi awa: 1) Compressor imasiyanitsidwa ndi mota, kotero kuti kompresa imakhala ndi ntchito zambiri; 2) Compressor yemweyo angagwiritsidwe ntchito pa mafiriji osiyanasiyana. Kuwonjezera pa refrigerants halogenated hydrocarbon, ammonia angagwiritsidwenso ntchito ngati firiji posintha zinthu za mbali zina; 3) Malingana ndi mafiriji osiyanasiyana ndi machitidwe ogwiritsira ntchito, ma motors a mphamvu zosiyana angagwiritsidwe ntchito.Zoyipa zazikulu zamagulu otseguka ndi: (1) Chisindikizo cha shaft ndi chosavuta kutulutsa, chomwe chimakhalanso chinthu chokonzekera kawirikawiri ndi ogwiritsa ntchito; (2) Galimoto yokhala ndi zida imazungulira pa liwiro lalikulu, phokoso la mpweya ndi lalikulu, ndipo phokoso la compressor palokha limakhalanso lalikulu, lomwe limakhudza chilengedwe; (3) Ndikofunikira kukonza cholekanitsa chosiyana chamafuta, choziziritsa mafuta ndi zida zina zovuta zamafuta, gawoli ndi lalikulu, losavuta kugwiritsa ntchito ndikulisamalira.
