1. Chokometsera choziziritsa kutentha cha piston chopanda chopopera.
Pakati pa mitundu yosiyanasiyana ya ma compressor oziziritsa, ma compressor a piston ndi oyamba kwambiri ndipo amagwiritsidwabe ntchito mobwerezabwereza. Mwachitsanzo, ma compressor oziziritsa a piston omwe amagwiritsidwa ntchito kwambiri mu zida zoziziritsira. Opanga wamba ndi awa: Emerson, Bitzer, ndi ma compressor ena.
Makhalidwe a ma compressor oziziritsa a piston okhala ndi mpweya wochepa: kupanikizika kwakukulu ndi mphamvu yoziziritsira, zosowa zochepa za zinthu, ukadaulo wokhwima, makina oziziritsa osavuta, koma amaopa kwambiri kugwedezeka kwamadzimadzi.
Pali zolakwika ziwiri zomwe zimachitika mu ma compressor oziziritsira a piston okhala ndi semi-hermetic: zolakwika za makina ndi zolakwika zamagetsi. Zolakwika zomwe zimachitika kawirikawiri ndi kuwonongeka kwa ndodo yolumikizira, crankshaft, valve plate ndi valve plate; zolakwika zamagetsi zimapezeka kwambiri mu short circuit, open circuit ndi kuyaka kwa mota.
2. Koperani compressor yoziziritsira.
Chokometsera cha scroll chimapangidwa makamaka ndi: diski yosuntha (chokokera chozungulira), diski yosasuntha (stator yozungulira), bulaketi, mphete yolumikizirana, chipinda chopanikizika kumbuyo, ndi shaft yosiyana. Ikhoza kugawidwa m'zigawo monga chipinda chopanikizika chochepa ndi chipinda chopanikizika kwambiri.
Chokometsera cha cavity chotsika mphamvu chimasonyeza kuti chipolopolo chonse chili ndi kutentha kochepa, ndipo chipolopolocho (kupatula doko lotulutsa utsi ndi chipolopolo chotulutsa utsi) chili ndi kuthamanga kochepa; chokometsera cha cavity chokwera mphamvu chimasonyeza kuti chipolopolocho chonse chili ndi kutentha kwakukulu, ndipo chipolopolocho (kupatula doko lotulutsa utsi ndi chipinda chotulutsira utsi) chili ndi kuthamanga kwakukulu.
Zinthu zomwe zimapangitsa kuti Scroll compressor igwire ntchito ndi izi: kugwira ntchito mokhazikika, kugwedezeka kochepa, malo ogwirira ntchito chete, zida zochepa zogwiritsidwa ntchito, kugwira ntchito mokhazikika, phokoso lochepa, kukhala nthawi yayitali, EER yapamwamba, ndipo zimagwiritsidwa ntchito mu makina oziziritsa ndi oziziritsira mpweya.
3. Chokometsera choziziritsira ndi siponji.
Chokometsera choziziritsira cha screw chimapangidwa makamaka ndi casing, rotor, bearing, shaft seal, balance piston, ndi chipangizo chosinthira mphamvu. Chokometsera choziziritsira cha screw chili ndi zomangira ziwiri zokhala ndi ming'alu ya mano ozungulira, zomwe zimapangitsa kusintha kwa voliyumu pakati pa mano, kuti njira yoyamwa ndi compressor ithe, ndipo mphamvu yoziziritsira imatha kusinthidwa mosalekeza pakati pa 10% ndi 100%. Ma compressor oziziritsira a screw tsopano amagwiritsidwa ntchito kwambiri mu zida zoziziritsira ndi HVAC.
Makhalidwe a ma compressor oziziritsira ndi screw: rotor, mphamvu ya bearing ndi kukana kutopa ndi okwera; kuchuluka kwa utsi sikukhudzidwa ndi kuthamanga kwa utsi; imasunga magwiridwe antchito apamwamba m'malo osiyanasiyana ogwirira ntchito; imatha kusintha mphamvu mosasinthasintha, osakhudzidwa ndi madzi.
Winawake adafunsa kale mu Refrigeration Encyclopedia Technology Group ngati ma screw compressor amaopa kugwedezeka kwamadzimadzi, ndipo anthu ambiri adayankha kuti saopa kugwedezeka kwamadzimadzi. Ndipotu, screw compressor imaopanso kugwedezeka kwamadzimadzi, koma screw compressor siikhudzidwa kwambiri ndi kuchuluka kochepa kwa madzi obwerera m'mbuyo, ndipo kuchuluka kwakukulu kwa madzi obwerera m'mbuyo kungayambitse vuto la compressor, lomwe likufunika kusamalidwa.
