Chiyambi cha mitundu ya ma compressor oziziritsa m'malo ozizira:
Pali mitundu yambiri ya ma compressor osungira zinthu zozizira. Ndi chipangizo chachikulu chomwe chimagwiritsidwa ntchito mu makina oziziritsira. Chimasintha mphamvu zamagetsi kukhala ntchito yamakina ndipo chimakanikiza firiji ya gasi yotsika kutentha komanso yotsika mphamvu kukhala mpweya wotentha kwambiri komanso wothamanga kwambiri kuti zitsimikizire kuti nthawi yoziziritsira ikuyenda bwino.
Ma compressor amagawidwa m'magulu otsatirawa:
1. Kompresa yoziziritsira ya semi-hemetic: Mphamvu yoziziritsira ndi 60-600KW, yomwe ingagwiritsidwe ntchito mu zida zosiyanasiyana zoziziritsira mpweya komanso zosungiramo zinthu zozizira.
2. Chokometsera choziziritsira chomwe chili ndi malo otsekedwa kwathunthu: Mphamvu yake yoziziritsira ndi yochepera 60KW, ndipo imagwiritsidwa ntchito kwambiri mu ma air conditioner ndi zida zazing'ono zoziziritsira.
3. Chokometsera choziziritsira cha screw: Mphamvu ya firiji ndi 100-1200KW, yomwe ingagwiritsidwe ntchito mu ma air conditioner akuluakulu ndi apakatikati komanso zida zoziziritsira zosungiramo zinthu zozizira.
Kusiyana pakati pa ma compressor oziziritsira osakhala ndi chotenthetsera ndi osakhala ndi chotenthetsera:
Msika wamakono uli makamaka ndi ma compressor osungira zinthu zozizira a piston okhala ndi semi-hermetic (tsopano ma compressor okulirapo), ma compressor osungira zinthu zozizira a piston okhala ndi semi-closed nthawi zambiri amayendetsedwa ndi ma mota a pole zinayi, ndipo mphamvu yawo yovomerezeka nthawi zambiri imakhala pakati pa 60-600KW. Chiwerengero cha masilinda ndi 2-8, mpaka 12.
Chokometsera chotsekedwa bwino ndi mota yomwe imagwiritsidwa ntchito zimagawana shaft yayikulu ndipo zimayikidwa mu casing, kotero chipangizo chotsekera shaft sichikufunika, zomwe zimachepetsa kuthekera kwa kutuluka kwa madzi.
ubwino:
Compressor ndi mota zimayikidwa mu chipolopolo cholumikizidwa kapena cholimba, ndipo zimagawana shaft yayikulu, yomwe sikuti imangoletsa chipangizo chotseka shaft, komanso imachepetsa kwambiri ndikuchepetsa kukula ndi kulemera kwa compressor yonse. Mapaipi okoka ndi otulutsa mpweya, mapaipi opangira ndi mapaipi ena ofunikira (monga mapaipi opopera), malo olowera magetsi ndi mabulaketi a compressor okha ndi omwe amalumikizidwa kunja kwa casing.
kusowa:
Sikophweka kutsegula ndi kukonza. Popeza injini yonse ya compressor imayikidwa mu chikwama chotsekedwa chomwe sichingathe kuchotsedwa, sikophweka kutsegula kuti ikonze mkati. Chifukwa chake, mtundu uwu wa compressor umafunika kuti ukhale wodalirika komanso wautali. Zofunikira pakuyika nazonso ndizokwera, ndipo kapangidwe kameneka kamagwiritsidwa ntchito kwambiri mu ma compressor oziziritsa omwe ali ndi mphamvu zochepa zomwe zimapangidwa mochuluka.
Ma compressor a semi-hermetic nthawi zambiri amagwiritsa ntchito kapangidwe kake konse ka silinda ndi crankcase, ndipo chivundikiro cha mota nthawi zambiri chimakhala chowonjezera cha crankcase ya silinda kuti achepetse malo olumikizirana ndikuwonetsetsa kuti ma motors a compressor ali bwino; Kuti zikhale zosavuta kuponyera ndi kukonza, zimapangidwa kuti zilekanitsidwe, ndipo zimalumikizidwa ndi ma flanges pamalo olumikizirana. Crankcase ndi chipinda cha mota zimalumikizidwa ndi mabowo kuti zithandize kubweza mafuta odzola.
Shaft yaikulu ya semi-hermetic compressor ili mu mawonekedwe a crank shaft kapena eccentric shaft; zina mwa ma motors omangidwa mkati zimaziziritsidwa ndi mpweya kapena madzi, ndipo zina zimagwiritsidwa ntchito kupumira nthunzi yapakatikati yogwira ntchito yotsika kutentha. Pa ma compressor a semi-hermetic omwe ali ndi mphamvu zochepa, mafuta a centrifugal nthawi zambiri amagwiritsidwa ntchito popaka mafuta.
Njira yopaka mafuta yamtunduwu ili ndi kapangidwe kosavuta, koma mphamvu ya compressor ikawonjezeka ndipo mafuta osakwanira, njira yopaka mafuta imasinthidwa.
ubwino:
1. Ikhoza kusintha kuti igwirizane ndi kuchuluka kwa kupanikizika komanso zofunikira pa kuzizira;
2. Kugwira ntchito bwino kwa kutentha kumakhala kwakukulu, ndipo mphamvu zomwe zimagwiritsidwa ntchito pa chipangizocho ndizochepa, makamaka kukhalapo kwa valavu ya gasi kumapangitsa kuti kusiyana ndi kapangidwe kake kuonekere bwino;
3. Zofunikira pa zinthuzo ndizochepa, ndipo zipangizo zachitsulo wamba nthawi zambiri zimagwiritsidwa ntchito, zomwe zimakhala zosavuta kuzikonza komanso zotsika mtengo;
4. Ukadaulowu ndi wokhwima pang'ono, ndipo pali zambiri zomwe zapezeka popanga ndi kugwiritsa ntchito;
5. Dongosolo lokhazikitsa ndi losavuta.
Ubwino wa semi-hermetic piston compressor womwe watchulidwa pamwambapa umapangitsa kuti ikhale mtundu wa mafiriji ogwiritsidwa ntchito kwambiri komanso opanga ambiri m'zida zosiyanasiyana zoziziritsira ndi zoziziritsira mpweya, makamaka m'malo ozizira apakatikati ndi ang'onoang'ono. Nthawi yomweyo, semi-hermetic piston compressor sikuti imangosunga ubwino wosavuta kusokoneza ndi kukonza compressor yotseguka, komanso imaletsa chipangizo chotsekera shaft, zomwe zimapangitsa kuti chitsekere. Chipangizocho chikhale chocheperako komanso chimakhala ndi phokoso lochepa. Madzi ogwirira ntchito akamaziziritsa injini, zimakhala zothandiza pakuchepetsa mphamvu ya makinawo komanso kuchepetsa kulemera kwake.
Pakadali pano, ma compressor oziziritsa a piston okhala ndi mpweya wochepa monga R22 ndi R404a amagwiritsidwa ntchito kwambiri posungira zinthu zozizira, zonyamula zinthu zoziziritsa, zoziziritsa, makabati owonetsera zinthu ndi mafiriji a kukhitchini.
Nthawi yotumizira: Feb-18-2022
