Inkinga yokubuyisa kawoyela ye-Reburficer Compressors bekulokhu kuyisihloko esishisayo ezinhlelweni zokuqandisa. Namuhla, ngizokhuluma ngenkinga yokubuyisa kawoyela ye-screw compressors. Ngokuvamile, isizathu sokubuyiselwa kwamafutha ampofu nge-compressor yesikulufa ikakhulukazi ngenxa yento yokuxubana yegesi yokuxubana kwamafutha okugcotshwa kwamafutha nesiqandisi sesikhathi sokusebenza. Ngesikhathi sokusebenza kohlelo lwefindisi, okuqandisayo kanye no-oyili wokuthambisa kwesiqandisi kuyancibilika, okwenza ukuba amafutha okugcoba akhishwe ku-condenser ngendlela ye-aerosol ne-Droplet gesi ngokusebenza komshini kanye nesiqandisi. Uma umhlukanisi kawoyela engasebenzi noma ukwakheka kwesistimu akukuhle, kuzodala umphumela wokuhlukanisa ompofu kanye nokubuyiselwa ko-oyela okopile.
1. Iziphi izinkinga ezizokwenzeka ngenxa yokubuya kwamafutha ampofu:
Ukubuyiselwa kwamafutha ampofu kwe-compressor yesikulufa kuzodala inani elikhulu lamafutha okuthambisa ukuze uhlale kupayipi e-evaporator. Lapho ifilimu kawoyela inyuka ngezinga elithile, kuzothinta ngqo ukupholisa kohlelo; Kuzoholela ekuqongeleleni kwamafutha okugcoba okwengeziwe ohlelweni, okuholela embuthanweni ononya, ukukhulisa izindleko zokusebenza nokwehlisa ukuthembeka kokusebenza. Ngokuvamile, ngaphansi kwe-1% yokugeleza kwegesi esiqandisini kuvunyelwe ukujikeleza ohlelweni ngenhlanganisela yomoya kawoyela.
2. Izisombululo zokubuya kawoyela ompofu:
Kunezindlela ezimbili zokubuyisa uwoyela ku-compressor, eyodwa ukubuyisa uwoyela ohlukanisi lowoyela, kanti enye ukubuyisa uwoyela kwipayipi lokubuya komoya.
Isihlukanisi samafutha sifakiwe epayipi eliphumayo le-compressor, elingahluka ngokuvamile ama-50-95% amafutha agijimayo. Umphumela wokubuya kawoyela muhle futhi ijubane liyashesha, elinciphisa kakhulu inani lamafutha angena ngepayipi lesistimu, ngaleyo ndlela amukele kahle ukusebenza ngaphandle kokubuya kwamafutha. isikhathi.
Okwezinhlelo ezibandayo zokugcina amapayipi ama-pipelines amade, kwagcwala amasistimu okwenza ama-Ice-wokwenza ama-Ice, kanye nemishini yokumisa iqhwa elinamazinga okushisa aphansi kakhulu, akujwayelekile ukubona ukuthi kungabikho mawoyela noma amaminithi amancane ngemuva kwemizuzu eyishumi ngemuva kokuqala umshini. Uhlelo olubi luzodala ukuthi i-compressor ivale ngenxa yokucindezela kawoyela okuphansi. Ukufakwa kwesihlukanisi samafutha asebenza kahle kulolu hlelo esiqandisi kungandisa kakhulu isikhathi sokusebenza se-compressor ngaphandle kokubuya kwamafutha, ukuze i-compressor idlule esigabeni senhlekelele ngaphandle kokubuya kwamafutha ngemuva kokuqala. Amafutha okugcoba okungahlukaniswa azongena kulolu hlelo futhi ageleze nesiqandisi esiqandisiwe ku-tube ukwenza ukujikeleza kwamafutha.
Ngemuva kokuthi uwoyela wokuthambisa ungena ku-evaporator, ngakolunye uhlangothi, ngenxa yokushisa okuphansi kanye ne-solubity ephansi, ingxenye yamafutha okugcoba ihlukaniswe nesiqandisi; Ngakolunye uhlangothi, izinga lokushisa liphansi futhi ukuhlakanipha kukhulu, uwoyela ohlukanisiwe kulula ukunamathela odongeni lwangaphakathi lweshubhu, futhi kunzima ukugeleza. Okwehlisa izinga lokushisa lokuhwamuka, kulapho kunzima kakhulu ukubuyisa uwoyela. Lokhu kudinga ukuthi ukwakhiwa nokwakhiwa kwepayipi lokuhwamuka kwepayipi kanye nepayipi elibuyayo kumele lilungele ukubuyiselwa kwamafutha. Umkhuba ojwayelekile ukusebenzisa ukwakheka kwepayipi ehlelayo futhi uqinisekise ukuthi i-velocity enkulu ye-airflow. Okwezinhlelo eziqandisini ezinamazinga okushisa aphansi, ngaphezu kokukhethwa kwamafutha asebenza ngamandla kawoyela, izixazululo ezikhethekile zivame ukungezwa ukuvikela uwoyela wokuthambisa kusuka kumashubhu we-capillary nama-valves e-capillary kanye nokunwetshwa, ukusiza uwoyela.
Kuzinhlelo zokusebenza ezisebenzayo, izinkinga zokubuyisa uwoyela ezibangelwa ukwakhiwa okungafanele kwe-evaporator kanye nepeni yegesi yokubuyisa akujwayelekile. Ngezinhlelo ezingama-R22 no-R404A, ukubuyiselwa kwamafutha kwe-evaporator enezikhukhula kunzima kakhulu, futhi ukwakheka kwamapayipi okubuyisa uwoyela kumele kuqaphele kakhulu. Ngohlelo olunjalo, ukusetshenziswa kokwehlukanisa kwamafutha asebenza kahle kunganciphisa kakhulu inani lamafutha okufaka ipayipi lesistimu, ukunwebeka ngempumelelo isikhathi lapho ipayipi lembuyiselo yegesi lingabuyiseli uwoyela ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini ngemuva kokuqala umshini.
Lapho i-compressor iphakeme kune-evaporator, i-oyili yokubuyisa ipayipi lokubuya mpo iyadingeka. Isicupho sokubuya kawoyela kufanele sibe njengehlandla ngangokunokwenzeka ukunciphisa isitoreji samafutha. Isikhala phakathi kokugoba okubuyayo kawoyela kufanele kufanelekile. Lapho inani lama-balling Return Bends likhulu, kufanele kungezwe uwoyela wokugcoba. Ukunakekelwa kumele futhi kuthathwe emigqeni yokubuyisa yezinhlelo zomthwalo eziguqukayo. Lapho umthwalo usuncishisiwe, ijubane lokubuya komoya lizokwehla, futhi ijubane liphansi kakhulu, elingalungile ekubuyiseleni uwoyela. Ukuze uqinisekise ukuthi uwoyela ubuyela ngaphansi komthwalo ophansi, ipayipi eliqonde mpo lingasebenzisa i-Riser ephindwe kabili.
Ngaphezu kwalokho, ukuqala okujwayelekile kwe-compressor akukuvumeli ukubuya kwamafutha. Ngoba isikhathi esiqhubekayo sokusebenza sifushane kakhulu, i-compressor iyama, futhi asikho isikhathi sokwakha ijubane eliqinile elisheshayo ngepayipi lokubuya, ngakho-ke uwoyela wokuthambisa angahlala epayipini. Uma uwoyela wokubuya ungaphansi kwamafutha okugijima, i-compressor izoba mfushane kawoyela. Isikhathi esifushane isikhathi esisebenzayo, isikhathi eside ipayipi, uhlelo oluyinkimbinkimbi kakhulu, inkinga evelele kakhulu i-Oyili Return Inkinga. Ngakho-ke, ngaphansi kwezimo ezijwayelekile, ungaqali i-compressor njalo.
Ukuntuleka kwamafutha kuzodala ukuntuleka okukhulu kokuthambisa. Imbangela yokushoda kwamafutha akuyona into engakanani futhi ushesha kangakanani isikulufa isikulufa compressor egijima, kodwa ukubuya kwamafutha ampofu ohlelweni. Ukufaka isihlukanisi samafutha kungasheshe ukubuyisa uwoyela futhi kunwebe isikhathi sokusebenza se-compressor ngaphandle kokubuya kwamafutha. Umklamo we-evaporator nomugqa wokubuya kumele athathe amafutha abuyiselwe. Izindlela zokulungisa ezifana nokugwema ukuqala kabusha, zihlambalaze njalo, ziphindaphinda esiqandisini ngesikhathi, futhi zithathe indawo ukugqoka izingxenye (ezinjengeBearings) ngesikhathi futhi zisiza ukubuyisa kawoyela.
Lapho uhlela uhlelo lokuqapha, ucwaningo ngenkinga yokubuya kawoyela lubaluleke kakhulu. Kuphela ngokubheka zonke izici, ingaqinisekiswa uhlelo oluphephile noluthembekile lwefriji.
