Screw compressor pafupifupi imatenga gawo lalikulu la msika wamakina a mpweya pamwamba pa 22kW, ndi mphamvu yadzina ya 0.7 ~ 1.0MPa.Chomwe chimapangitsa kuti izi zitheke ndikuwongolera magwiridwe antchito ake ndi kudalirika, komanso kuchepetsa kukonza ndikuchepetsa ndalama zoyambira.
Komabe, kompresa ya pistoni yochita kawiri ikadali kompresa yothandiza kwambiri.Mawonekedwe a rotor a screw amachepetsa magwiridwe antchito apamwamba a screw compressor.Chifukwa chake, mbiri yabwino ya rotor, kukonza bwino komanso kapangidwe katsopano ndiye zinthu zazikulu za screw compressor.
Mwachitsanzo, kompresa yothamanga kwambiri, yoyendetsa mwachindunji imatha kutulutsa mphamvu ya 0.7MPa ndi mpweya wa 0.13-0.14m³, womwe ndi 90-95% wa kompresa ya pistoni yochita kawiri.Kwa ogwiritsa ntchito ambiri, pokhapokha nthawi zina pomwe mphamvu yogwiritsira ntchito mphamvu imakhala yochulukirapo, chifukwa cha ndalama zake zoyambira (mtengo wogula), kompresa ya piston yogwira ntchito pawiri nthawi zambiri sikhala yotsika mtengo chifukwa cha nthawi yayitali yobwezera ndalama.
Compressor yosamalidwa bwino imatha kugwira ntchito kwa zaka 10 kapena kuposerapo.Panthawi imodzimodziyo, dongosolo lake lolamulira ndi matenda olakwa ndi luso lokonzekera likhoza kusonyeza kusiyana kwa kusintha kwa mafuta kutengera kutentha kwa ntchito, komwe kumapangitsanso kudalirika ndi moyo wa kompresa .
sungani
Pamitengo yokonza, ma screw compressor ali ndi zabwino kuposa ma piston compressor.Ma compressor a pistoni ochita kawiri amakhala ndi nthawi yayitali yokonza kuposa zomangira.Vavu, mphete ya pistoni ndi zida zina zovala pa pistoni kompresa zimafunikira kukonzedwa pafupipafupi.
Kukonza kwakukulu kwa screw compressor ndi mafuta, fyuluta yamafuta ndi cholekanitsa mafuta.Nthawi zina, m'malo mwa screw rotor mpweya ndi zida zoyendera mbali zimafunikira ndalama zambiri, koma zimatha kugwira ntchito kwa zaka 10 kapena kupitilira apo.
Msonkhano wokhazikika wa screw compressor uli ndi chowongolera chotengera microprocessor kapena mphamvu zamagetsi.Owongolera awa amathandizira screw rotor kusunga katundu 100% ya nthawiyo.Imodzi mwa ntchito zazikulu za woyang'anira ndikusintha kayendedwe ka mpweya kuti makina azitha kuthamanga kwambiri pansi pa katundu wathunthu, kulemedwa pang'ono komanso kusanyamula katundu.
Zowongolera zina zamakina zili ndi ntchito zina zambiri zothandiza, monga kuyang'anira kachitidwe, chenjezo lotseka ndi chikumbutso chokonzekera.
Chipinda chokhala ndi pistoni yoyendetsedwa bwino komanso yosamalidwa kawiri ndi yopindulitsa kugwira ntchito.Zida zamtunduwu zimatha kulumikizidwa ndikugawidwa, pogwiritsa ntchito kukonza ndi kukonza nthawi zonse kuti zikhale njira yabwino yopanikizira mpweya.
mafuta
Malinga ndi mikhalidwe yosiyanasiyana yamafuta, ma compressor a piston amatha kugawidwa m'mitundu iwiri: yothira mafuta komanso yopanda mafuta.Mugawo lopaka mafuta, mafuta opaka mafuta amalowetsedwa mu silinda yopondereza kuti achepetse kukangana pakati pa silinda ndi mphete ya pistoni.Nthawi zambiri, mphete ya pistoni yothira bwino imatha zaka zingapo, ndipo kugwiritsa ntchito zida zapamwamba kumatha kukulitsa moyo wa mphete ya pistoni mumtundu wowuma mpaka 8000h.
Mtengo wapakati pa injini za pistoni zopaka mafuta komanso zosapaka mafuta ndizofunikira kuziganizira.Nthawi zina, mpweya wopanda mafuta kapena gasi umafunika.Ndalama zoyamba za unit yopanda mafuta ndi 10-15% yapamwamba, ndipo pali kusiyana kochepa pakati pa kugwiritsa ntchito mphamvu ndi mphamvu.Kusiyana kwakukulu kwagona pakukonza kofunikira pamitundu iwiri ya mayunitsi.Mtengo, mtengo wokonzanso wa unit unlubricated ndi kanayi kapena kuposa wa unit mafuta.
Mphamvu yosakwanira komanso kulemera kwa pistoni kompresa ndizomwe zimathandizira pakuyika mtengo.Nthawi zambiri, pisitoni imafuna maziko olemera komanso maziko olimba.Zachidziwikire, wopanga kompresa adzapereka zofunikira zofunika kuti amange maziko.
Ngakhale mtengo woyambira ndi kuyika kwa pisitoni kompresa ndi wochuluka kuposa wa screw compressor, moyo wa pisitoni kompresa posamalidwa bwino ukhoza kukhala 2 mpaka 5 nthawi yayitali kuposa ya screw compressor.
Kwa zaka zambiri, pisitoni kompresa yakhala makina odalirika olemetsa.Ndi kupita patsogolo kwaukadaulo, popereka mpweya wabwino kwambiri, mtengo wokonza ma compressor a piston wachepetsedwa kwambiri.M'mayunitsi okhala ndi kuthamanga kwadzina kwa 0.7 ~ 1.0MPa, kaya ndi mpweya woponderezedwa kapena mpweya wina, pisitoni kompresa akadali chisankho chabwino kwambiri.
