Kuwunika kwa mfundo yogwirira ntchito ya compressor air compressor system

Injini yayikulu/magalimoto:

The single screw air compressor imatchedwanso worm air compressor. Ma meshing awiri a single screw air compressor amapangidwa ndi 6-head screw ndi 2 11-tooth star mawilo. Ma meshes a nyongolotsi okhala ndi mawilo a nyenyezi ziwiri nthawi imodzi ngakhale mphamvu ya nyongolotsi imakhala yolinganizika, kusamukako kumawirikiza kawiri. Nthawi zambiri timati screw compressor nthawi zambiri imatanthawuza kuwirikiza kawiri.
Ma screw-type (ie, mapasa-screw) amakhala ndi ma rotor okhala ndi mano ozungulira omwe amazungulira mozungulira mozungulira. Rotor yokhala ndi dzino lotukuka pansi imatchedwa rotor yabwino, ndipo rotor yokhala ndi dzino lopindika imatchedwa rotor negative. Ndi kuzungulira kwa rotor m'thupi, kuchuluka kwa ntchito chifukwa cha kuwukira kwa dzino kapena kutulutsa ndikusintha kosalekeza, motero nthawi ndi nthawi kusintha voliyumu pakati pa mano a rotor, kuti akwaniritse cholinga choyamwa, kuponderezana ndi kutopa.
Makina akuluakulu ndiye gawo lalikulu la makina omata, mtundu uliwonse wa makina omangira makina ake akulu ndi makina ogwirira ntchito ndi ofanana.

A. Kupuma mukuchita

The rotor atembenuza, ndi mano mosalekeza kuchokera Yin Yang rotor rotor wa dzino, dzino pakati buku kukula pang'onopang'ono, ndi kuyamwa orifice ogwirizana, mpweya ndi kuyamwa orifice mu voliyumu pakati mano, mpaka voliyumu kufika pa mtengo pazipita pakati mano, ndi kuyamwa orifice kusagwirizana, olowa kanthu ndi dzino ndi zipolopolo kutsekedwa voliyumu pakati pa mano, kuyamwa ndondomeko. Ndikoyenera kudziwa kuti voliyumu pakati pa mano a Yang rotor ndi Yin rotor sagwirizana wina ndi mnzake.

B. Njira yophatikizira

Rotor imapitilira kuzungulira. Voliyumu yapakati pa mano a Yin ndi Yang rotor isanalumikizidwe, mpweya wa voliyumu pakati pa mano a rotor ya Yang umakanizidwa poyamba ndi kulowerera kwa mano a Yin rotor. Pambuyo pa ngodya inayake, voliyumu pakati pa mano a Yin ndi Yang rotor imalumikizidwa ndikupanga voliyumu yofanana ndi v (voliyumu yoyambira). Ndi kulumikizana kwa mano awiri a rotor, voliyumu yoyambira imakankhidwira patsogolo pang'onopang'ono ndipo voliyumu imachepetsedwa pang'onopang'ono kuti izindikire njira yopondereza ya gasi. Njira yopondereza imatsirizidwa mpaka voliyumu ya chinthu italumikizidwa ndi exhaust orifice.

C. Njira yotulutsa mpweya

Pamene rotor ikuzungulira, voliyumu ya chinthu choyambirira imachepa, ndipo mpweya woponderezedwa umatumizidwa ku chitoliro chotulutsa mpweya, ndondomekoyi imapitirira mpaka voliyumu ndi yaying'ono kwambiri.
Ndi kasinthasintha kosalekeza kwa rotor, kuyamwa pamwambapa, kuponderezana, kutulutsa mpweya, kuchuluka kwa chinthu chilichonse motsatizana kumagwira ntchito, kumapanga kuzungulira kwa wononga firiji kompresa.
Kuchokera pakuwunika kwazomwe tafotokozazi, zikuwoneka kuti ma rotor awiri amatembenukira kumbali yodyera wina ndi mzake, ndiko kuti, mbali yomwe mano a convex ndi mano a concave amachitirana wina ndi mzake, ndipo mpweya wa mpweya umachepa ndipo umapanga kuthamanga kwakukulu, komwe kumatchedwa malo othamanga kwambiri. M'malo mwake, wononga anatembenukira ku mbali moyang'anizana wina ndi mzake, ndiko kuti, otukukira mano mano ndi concave mano wina ndi mzake kuchokera mbali, voliyumu pakati pa mano mu kukulitsa kuthamanga m'munsi, lotchedwa otsika mavuto m'dera. Madera awiriwa amasiyanitsidwa ndi mzere wolumikizana ndi nyumba ndi rotor, ndipo ndege ya axial ya rotor iwiri imatha kuonedwa ngati mawonekedwe pakati pa madera apamwamba ndi otsika. Kuonjezera apo, njira yozungulira yomwe imapangidwa ndi mizere ya ma meshing pakati pa Yin ndi Yang rotor imapangitsa kuti mpweya mu voliyumu ya chinthu choyambira usunthike mozungulira kuchokera kumapeto mpaka kumapeto kwa utsi uku akukanikizidwa.
Screw kompresa ngati kompresa rotary, mu kapangidwe ali ndi makhalidwe a centrifugal kompresa, mfundo ntchito ndi wa gulu la zabwino kusamuka kompresa.

kuipa

·Kulondola kwa makina a spiral rotor space space ndikokwera kwambiri
· Mzere wa meshing pakati pa ma rotor sungathe kukwaniritsa kusindikiza kwabwino kwapakati ndipo umachepetsedwa ndi kuuma kwa rotor. Pakadali pano, screw compressor siyingafikire kuthamanga kwambiri kumapeto
· Sing'anga nthawi ndi nthawi amadutsa mumsewu woyamwa komanso wotulutsa mpweya pa liwiro lalikulu, kudzera pakutha kwa ming'alu ndi zifukwa zina, kuti phokoso la compressor likhale lalikulu, ndikofunikira kuchitapo kanthu zoletsa phokoso kuti muchepetse phokoso.

Chifukwa cha mawonekedwe omwe ali pamwambapa, screw compressor nthawi zambiri imagwiritsidwa ntchito pazotsatira zotsatirazi

·Magalimoto sakwera kwambiri ·Amafunika nthawi yayitali kuti aziyenda bwino ·Kuchepa kwa exhaust pressure

galimotoyo

Zimapangidwa ndi chimango cha mpweya, mpando wakumapeto woyamwa ndi mpando wakutha, womwe ndi gawo lalikulu la kompresa. Thupi ndilo gawo lapakati lomwe limalumikiza gawo lililonse, limapereka malo oyenera osonkhana pagawo lililonse, limatsimikizira kuti Yin ndi Yang rotor meshing mu silinda, imagwira ntchitoyo modalirika. Maonekedwe a nkhope yomaliza ndi ∞, yomwe ili yoyenera kwa silinda yakunja ya ma rotor awiri a meshing, kotero kuti rotor imayikidwa molondola m'thupi. Khoma lamkati la thupi limaperekedwa ndi radial suction orifice yomwe imakwaniritsa zofunikira za rotor rotation Angle kuonetsetsa kuti rotor ikhoza kuzindikira njira yoyamwa bwino panthawi yozungulira.
The kuyamwa ndi utsi mapeto mpando ndi kusindikiza cholumikizira ili kutsogolo ndi kumbuyo malekezero a injini thupi. Izo osati zimapangitsa mapeto nkhope chisindikizo cha injini thupi, komanso amapereka kubala msonkhano udindo wa Yin ndi Yang rotor ndi kuthandizira rotor.

Rotor

Zigawo zazikulu za kuponderezedwa kwa voliyumu yosinthika zimapangidwa ndi Yin ndi Yang rotor. Mbiri ya rotor imapangidwa ndi zida zapadera zamakina, zida zapadera zodulira, ndi imodzi mwamagawo ofunikira a kompresa. Mbiri ya rotor nthawi zambiri imakhala ya unilateral asymmetrical cycloid - mbiri ya arc. Yin ndi Yang rotor mu dongosolo la njira ziwiri zotsatirazi.
Rotor yabwino imalumikizidwa ndi mota ngati chozungulira chogwira kuti chisamutse torque ndikuyendetsa chozungulira choyipa (chozungulira choyendetsedwa) kuti chizungulire kudzera muubwenzi wa meshing. Ma rotor a Yin ndi Yang amatumiza torque polumikizana ndi zida zoyendetsera galimoto zoyendetsedwa ndi magiya awo.

Kuchitira

Kunyamula ndikuthandizira Yin ndi Yang rotor, ndikuwonetsetsa kuti magawo ozungulira kwambiri. Mapeto a injini nthawi zambiri amatenga zodzigudubuza kuti zithandizire. Kachiwiri, pamene rotor imazungulira ndikukakamiza mpweya, axial thrust imapangidwa. Pofuna kuthana ndi mphamvu ya axial iyi, mapeto ena a rotor amatenga oblique column bearing, zomwe sizimangogonjetsa mphamvu ya axial ya rotor, komanso imakhala ndi mphamvu yozungulira.  
Ma screw compressor ambiri amathiridwa ndi jekeseni wamafuta. Kupyolera mu kusakaniza kwa mafuta odzola ndi kudula mu kompresa, ndi kutuluka kwa sing'anga kwa mafuta ndi kusindikiza makina.
Ubwino wake ndi awa
•Chepetsani kutentha kwa mpweya.
· Chepetsani kutayikira kwapang'onopang'ono ndikuwongolera kusindikiza
· Limbikitsani mafuta azigawo, sinthani moyo wautumiki wa magawo
· Imakhala ndi mayamwidwe ndi kunyowetsa pamafunde amawu ndipo imatha kuchepetsa phokoso
·Chotsani zonyansa zamakina ndi kuchepetsa kutha
Komabe, chifukwa cha kuchuluka kwa jekeseni wamafuta, ndikofunikira kuwonjezera mafuta opaka mafuta ndi cholekanitsa mafuta ndi gasi pamalo opangira kompresa, zomwe zidzakulitsa kuchuluka kwake komanso zovuta za unit. Panthawi imodzimodziyo, njirayi singagwiritsidwe ntchito pazinthu zosaipitsa. Chifukwa chake, palinso magawo amakina a screw compressor ndi mafuta opanda mafuta.
Kugwiritsiridwa ntchito kwa kompresa wopanda mafuta kumakhala ndi zofunika kwambiri pa chilolezo chololeza, kuuma ndi kulemera kwa rotor ndi mtundu wa makina a unit yonse.
