Motar kwandishan kwandishan.
Motar kwandishan kwampreso shine zuciyar tsarin sanyaya iska na mota, wanda ke taka rawa na matsawa da jigilar tururi mai sanyi.
An kasu na'urorin damfara zuwa nau'i biyu: ƙaura maras canzawa da ƙaura mai ma'ana.
Compressors na kwandishan bisa ga yanayin aiki na ciki daban-daban, gabaɗaya zuwa ga maimaituwa da juyawa.
Dangane da ka'idodin aiki daban-daban, ana iya raba na'urorin kwantar da iska zuwa kompressors na ƙaura akai-akai da masu matsawa masu sauyawa.
Compressor na yau da kullun
Matsar da kwampreshin matsawa na yau da kullun yana daidai da haɓakar saurin injin, ba zai iya canza wutar lantarki ta atomatik bisa ga buƙatun firiji ba, kuma tasirin injin injin yana da girma. Ikon sarrafa shi gabaɗaya shine ta hanyar tattara siginar zafin jiki na kanti na evaporator, lokacin da zafin jiki ya kai ga yanayin da aka saita, an saki kamannin lantarki na kwampreso, kuma compressor ya daina aiki. Lokacin da zafin jiki ya tashi, ana haɗa nau'in lantarki na lantarki kuma compressor ya fara aiki. Hakanan ana sarrafa kwamfaran matsawa akai-akai ta hanyar matsa lamba na tsarin kwandishan. Lokacin da matsa lamba a cikin bututun ya yi yawa, compressor ya daina aiki.
Mai canza matsawa kwandishan kwandishan
Maɓallin maɓalli masu canzawa suna iya daidaita ƙarfin wutar lantarki ta atomatik gwargwadon yanayin da aka saita. Tsarin kula da kwandishan ba ya tattara siginar zafin jiki na fitarwar iska, amma ta atomatik yana daidaita yanayin zafin fitarwa ta hanyar sarrafa ma'aunin matsawa na kwampreso bisa ga canjin siginar matsa lamba a cikin bututun kwandishan. A cikin duka tsarin na'ura na refrigeration, compressor yana aiki ko da yaushe, kuma daidaitawar ƙarfin refrigeration gaba ɗaya ya dogara ne akan mai sarrafa matsa lamba da aka sanya a cikin compressor don sarrafawa. Lokacin da matsa lamba a babban matsin ƙarshen bututun kwandishan ya yi girma sosai, matsa lamba mai daidaita bawul yana karkatar da bugun piston na kwampreso don rage ƙimar matsawa, wanda zai rage ƙarfin firiji. Lokacin da matsa lamba a ƙarshen ƙarshen matsa lamba ya ragu zuwa wani matsayi kuma matsa lamba a ƙarshen ƙarancin matsa lamba ya tashi zuwa wani matsayi, matsa lamba mai daidaitawa bawul yana ƙara bugun piston don inganta ƙarfin sanyaya.
Dangane da hanyoyin aiki daban-daban, ana iya raba compressors gabaɗaya zuwa juzu'i da jujjuyawar, na'ura mai ɗaukar nauyi na yau da kullun suna da nau'in haɗin sandar crankshaft da nau'in piston axial, na yau da kullun rotary compressors suna da nau'in rotary vane da nau'in gungurawa.
Crankshaft da haɗa sandar kwampreso
Tsarin aiki na wannan kwampreso za a iya raba zuwa hudu, wato matsawa, shaye-shaye, fadadawa, tsotsa. Lokacin da crankshaft ya juya, piston yana motsawa ta hanyar haɗin haɗin don amsawa, kuma ƙarar aiki wanda ya ƙunshi bangon ciki na Silinda, shugaban Silinda da saman saman piston zai canza lokaci-lokaci, don haka yana taka rawar matsawa sufuri na refrigerant a cikin tsarin refrigeration. The crankshaft haɗa sanda compressor ne na farko ƙarni na kwampreso, wanda aka yadu amfani, balagagge masana'antu fasahar, sauki tsari, da kuma low bukatun ga aiki kayan da fasaha da fasaha, kuma in mun gwada da low cost. Ƙarfafawa mai ƙarfi, zai iya daidaitawa zuwa nau'i mai yawa na matsa lamba da buƙatun ƙarfin sanyaya, mai kyau kula.
Duk da haka, crankshaft connecting sanda compressor shima yana da wasu kurakurai a bayyane, kamar rashin iya samun saurin gudu, injin yana da girma kuma yana da nauyi, kuma ba shi da sauƙin cimma nauyi. Shaye-shaye yana katsewa, motsin iska yana da saurin canzawa, kuma akwai babban girgiza yayin aiki.
Saboda halaye na sama na crankshaft mahada kwampreso, akwai ƴan ƙananan komfutoci masu amfani da wannan tsarin, kuma crankshaft link compressor yawanci ana amfani dashi a cikin babban tsarin kwantar da iska na bas da manyan motoci.
Axial piston compressor
Axial piston compressors za a iya kira na biyu ƙarni na compressors, kowa lilo farantin ko karkata farantin compressors, wanda shi ne na al'ada samfurin a mota kwandishan compressors. Babban abubuwan da ke tattare da kwampresar farantin mai karkata su ne babban shaft da farantin da aka karkata. Ana shirya kowace silinda a tsakiyar da'irar kwampreso spindle, kuma alkiblar motsin piston yana layi daya da na'urar kwampreso. Yawancin kwampressor na farantin karfe ana yin su ne da pistons masu kai biyu, irin su axial 6-cylinder compressors, sannan silinda 3 a gaban kwampressor, sauran 3 cylinders a bayan kwampreso. Pistons masu kai biyu suna zamewa a gaban silinda, piston ɗaya yana matsawa tururi mai sanyi a cikin silinda ta gaba, ɗayan kuma yana zana tururi mai sanyi a cikin silinda ta baya. Kowane Silinda yana sanye da bawul mai ƙarfi da ƙarancin ƙarfi, kuma ana amfani da bututu mai ƙarfi don haɗa ɗakin babban matsa lamba na gaba da na baya. Ana gyara farantin da aka karkata tare da sandal ɗin kwampreso, sannan gefen farantin ɗin yana sanye cikin wani tsagi a tsakiyar fistan, kuma fistan ɗin da gefen farantin ɗin suna goyan bayan ƙwan ƙarfe na ƙarfe. Lokacin da dunƙulewar ta juya, farantin mai karkata shima yana jujjuya shi, kuma gefen farantin ɗin yana tura piston don mayar da martani. Idan farantin da aka karkata ya juya sau ɗaya, pistons biyu kafin da bayan kowannensu sun cika zagayowar matsawa, shayewa, faɗaɗa da tsotsa, wanda yayi daidai da silinda biyu. Idan axial 6-Silinda kwampreso ne, 3 Silinda da 3 pistons biyu-head pistons ana rarraba daidai a kan sashin Silinda, kuma lokacin da spindle ya juya sau ɗaya, yana daidai da matsayin 6 cylinders.
