Umshini wokomisa ubhekisela kumshini osetshenziswa ukomisa into ngokusebenzisa amandla okushisa ukuze kuncishiswe umswakama wezinto.Isomisi sihwamulisa umswakama kumpahla (ngokuvamile ibhekisela emanzini nezinye izakhi zoketshezi eziguquguqukayo) ngokufudumeza ukuze uthole into eqinile enomswakama oshiwo.Inhloso yokomisa ukuhlangabezana nezidingo zokusetshenziswa kwempahla noma ukucubungula okwengeziwe.Imishini yokomisa ihlukaniswe yaba izinhlobo ezimbili, okomisa ukucindezela okujwayelekile kanye nokomisa i-vacuum, kuye ngengcindezi yokusebenza.Izimiso zokusebenza ze-adsorption dryer nezomisi eziqandisa nazo zethulwa ngokuningiliziwe.

1. Umgomo Osebenzayo We-Adsorption Air Dryer

I-adsorption dryer ifinyelela umphumela wokumisa "ngokushintsha kwengcindezi" (isimiso sokushintshashintsha kwengcindezi i-adsorption).Ngenxa yokuthi ikhono lomoya lokubamba umhwamuko wamanzi lilinganisa ngokuphambene nokucindezela, omunye womoya owomile (obizwa ngokuthi umoya wokuvuselela kabusha) uyacindezelwa futhi unwetshwe kungcindezi yasemkhathini.Lokhu kushintsha kwengcindezi kubangela ukuthi umoya owandisiwe wome nakakhulu futhi ugeleze emoyeni ongaxhumekile.Kusendlalelo se-desiccant esivuselelwe (okungukuthi, umbhoshongo wokomisa obambe umhwamuko wamanzi owanele), igesi eyomile yokuvuselela izothatha umswakama ku-desiccant futhi iwukhiphe esomisini ukuze ufeze injongo yokunciphisa umswakama.Le mibhoshongo emibili isebenza ngemijikelezo ngaphandle komthombo wokushisa, ihlinzeka ngokuqhubekayo umoya owomile, ocindezelwe ohlelweni lwegesi lomsebenzisi.

2. Isimiso sokusebenza sesomisi somoya esiqandisiwe

I-dryer yefriji isekelwe kumgomo wokukhipha umswakama esiqandisini.Igesi ecindezelwe ekhishwa ku-compressor yomoya ipholiswa ngohlelo lwesiqandisi sokucindezelwa oluvalwe ngokugcwele, futhi inani elikhulu lesitimu esigcwele kanye namaconsi ajiyile enkungu kawoyela equkethwe kuyo ayahlukaniswa.Okuzo kwenziwa.Ekugcineni, lapho ikhishwa i-drainer ezenzakalelayo, igesi ecindezelwe eshisayo ingena kumshini wokushisa ophansi we-precooler, ishintshisane ngokushisa negesi eyomile yokushisa ephansi evela ku-evaporator, futhi ingena ku-evaporator yesomisi sokupholisa.Pholisa uhlelo lwesiqandisi ngemva kokwehlisa izinga lokushisa.Ukushintshaniswa kokushisa kwesibili nomhwamuko oyisiqandisi kwehlisa izinga lokushisa lifinyelele eduze nezinga lokushisa elihwamukayo lesiqandisi.Phakathi nezinqubo ezimbili zokupholisa, umhwamuko wamanzi kugesi ecindezelweyo uyajiya ube amaconsi amanzi awuketshezi afaka umfudlana womoya kusihlukanisi somusi lapho ehlukaniswa khona.Amanzi awuketshezi awayo akhishwa emshinini nge-drainer ezenzakalelayo, futhi igesi eyomile ecindezelwe izinga lokushisa layo lehlile ingena ku-pre-cooler bese ishintshana ngokushisa ne-pre-cooler.Igesi egcwele amanzi esanda kufakwa, eyenyuse izinga layo lokushisa, ihlinzeka ngegesi eyomile ecindezelwe enomswakama ophansi (okungukuthi indawo ephansi yamazolo) kanye nomswakama ophansi ohlobene nendawo yokukhipha umoya yokomisa izinga lokushisa eliphansi.Ngesikhathi esifanayo, sebenzisa ngokugcwele umthombo womoya obandayo we-outlet air ukuze uqinisekise umphumela wokufingqa wesistimu yesiqandisi somshini kanye nekhwalithi yomoya endaweni yokuphuma komshini.Iziqandisi zokomisa isiqandisi seziphenduke inketho yokuqala njengemishini yokuhlanza iziteshi ze-compressor zomoya ezimbonini ezahlukahlukene ngenxa yokusebenza kwazo okuthembekile, ukuphatha okulula kanye nezindleko eziphansi zokusebenza.
