Ma compressor a screw amakhala pafupifupi gawo lalikulu pamsika wa makina ampweya opitilira 22kW, ndi mphamvu yocheperako ya 0.7~1.0MPa. Zomwe zimapangitsa izi kukhala bwino ndikuwongolera magwiridwe antchito ake komanso kudalirika kwake, komanso kuchepetsa kukonza ndi kuchepetsa ndalama zoyambira.
Komabe, compressor ya piston yogwira ntchito kawiri ndiyo ikadali compressor yogwira ntchito bwino kwambiri. Kapangidwe ka rotor ya screw kamachepetsa kuchuluka kwa mphamvu ya screw compressor. Chifukwa chake, mawonekedwe abwino a rotor, kukonza bwino komanso kapangidwe katsopano ndizomwe zimapangitsa kuti screw compressor ikhale yogwira ntchito bwino.
Mwachitsanzo, compressor yothamanga pang'ono komanso yoyendetsa mwachindunji imatha kupereka mphamvu yotulutsa ya 0.7MPa ndi voliyumu ya mpweya ya 0.13-0.14m³, yomwe ndi 90-95% ya compressor ya piston yogwira ntchito kawiri. Kwa ogwiritsa ntchito ambiri, pokhapokha ngati nthawi zina mphamvu imagwiritsidwa ntchito kwambiri, chifukwa cha ndalama zake zoyambira zapamwamba (mtengo wogulira), compressor ya piston yogwira ntchito kawiri nthawi zambiri siigwira ntchito bwino chifukwa cha nthawi yayitali yobwezera ndalama.
Chokometsera chokulungidwa bwino chingathe kugwira ntchito kwa zaka 10 kapena kuposerapo. Nthawi yomweyo, njira yake yowongolera yokhala ndi luso lozindikira zolakwika ndi kukonza zinthu imatha kusonyeza kusiyana kwa kusintha kwa mafuta kutengera kutentha kwa ntchito, zomwe zimathandiziranso kudalirika ndi moyo wa chokometsera.
sungani
Pa ndalama zokonzera, ma screw compressor ali ndi ubwino kuposa ma pisitoni compressor. Ma double-acting piston compressors ali ndi nthawi yochepa yokonza kuposa ma screw compressor. Valavu, mphete ya piston ndi zida zina zosweka pa piston compressor zimafunika kukonzedwa nthawi ndi nthawi.
Kusamalira kwakukulu kwa screw compressor ndi mafuta, fyuluta yamafuta ndi cholekanitsa mafuta. Nthawi zina, kusintha kwa screw rotor air ndi zida zowunikira kumafuna ndalama zambiri, koma nthawi zambiri zimatha kugwira ntchito kwa zaka 10 kapena kuposerapo.
Chojambulira chojambulira chokhazikika chimakhala ndi chowongolera chozikidwa pa microprocessor kapena chowongolera chamagetsi. Zowongolera izi zimathandiza chozungulira chowongolera kuti chizisunga katundu nthawi zonse. Chimodzi mwa ntchito zazikulu za chowongolera ndikusintha kayendedwe ka mpweya kuti makina azigwira ntchito bwino kwambiri pansi pa katundu wonse, katundu pang'ono komanso wopanda katundu.
Ma screw machine controller ena ali ndi ntchito zina zambiri zothandiza zowongolera, monga kuyang'anira ntchito, chenjezo lotseka ndi chikumbutso chokonza.
Chipangizo chokhala ndi compressor ya piston yogwira ntchito bwino komanso yosamaliridwa bwino ndi chothandiza pa ntchito. Zipangizo zamtunduwu zimatha kugwirizanitsidwa ndikugawidwa, pogwiritsa ntchito kukonza ndi kukonza nthawi zonse kuti zikhale njira yopambana yopumira mpweya.
kudzola mafuta
Malinga ndi momwe mafuta amagwiritsidwira ntchito, ma compressor a piston amatha kugawidwa m'mitundu iwiri: mafuta ndi osapakidwa mafuta. Mu unit yopaka mafuta, mafuta opaka mafuta amalowetsedwa mu silinda yokanikizira kuti achepetse kukangana pakati pa silinda ndi mphete ya piston. Nthawi zonse, mphete ya piston yopaka mafuta bwino imatha kukhala kwa zaka zingapo, ndipo kugwiritsa ntchito zipangizo zamakono kumatha kukulitsa moyo wa mphete ya piston mu unit youma mpaka maola opitilira 8000.
Mtengo pakati pa injini za pistoni zodzola ndi zosadzola ndi chinthu chofunikira kuganizira. Nthawi zina, mpweya wopanikizika wopanda mafuta kapena gasi umafunika. Ndalama zoyambira zogwiritsira ntchito chipangizo chosadzola mafuta ndi 10-15% kuposa, ndipo pali kusiyana kochepa pakati pa kugwiritsa ntchito mphamvu ndi kugwiritsa ntchito bwino. Kusiyana kwakukulu kuli pakukonza komwe kumafunika pa mitundu iwiri ya mayunitsi. Mtengo, mtengo wokonza chipangizo chosadzola mafuta ndi kanayi kapena kuposerapo kuposa cha chipangizo chodzola mafuta.
Mphamvu yosalinganika komanso kulemera kwakukulu kwa compressor ya piston ndizomwe zimapangitsa kuti mtengo wake ukhale wotsika. Nthawi zambiri, piston unit imafuna maziko olemera komanso maziko olimba. Zachidziwikire, wopanga compressor amapereka deta yoyenera yofunikira kuti amange maziko.
Ngakhale ndalama zoyambira zoyika ndi kuyika kwa compressor ya pistoni ndi zambiri kuposa za compressor ya screw, nthawi yogwira ntchito ya compressor ya pistoni ikasamalidwa bwino imatha kukhala yayitali nthawi ziwiri mpaka zisanu kuposa ya compressor ya screw.
Kwa zaka zambiri, makina osindikizira a piston akhala makina odalirika komanso olemera. Chifukwa cha kupita patsogolo kwa ukadaulo, ngakhale akupereka mpweya wabwino kwambiri, ndalama zosamalira ma compressor a piston zachepetsedwa kwambiri. M'mayunitsi omwe ali ndi mphamvu yocheperako ya 0.7 ~ 1.0MPa, kaya ndi mpweya wopanikizika kapena mpweya wina, makina osindikizira a piston akadali chisankho chabwino kwambiri.
