Isixhobo sokugcina ubushushu esibandayo njengentliziyo yenkqubo yonke yokukhenkcisa, kufuneka sigxile ingqalelo, nokuba ukusilela okuncinci kunokubangela ukungaphumeleli kwenkqubo yokukhenkcisa ebandayo, okubangela ilahleko, ngoko ke umqhubi osebenzayo kwinkqubo yokukhenkcisa kufuneka alumke, alumke. Apha ukukunika isishwankathelo seengxaki zokusebenza kwesixhobo sokugcina ubushushu.
Okokuqala, ngenxa yeziphene kwiindawo ezihambayo ezibangelwa kukusebenza kwecompressor yokugcina izinto ezibandayo, le meko ingaqhelekanga ichazwe ngezantsi:
1, kunye nokutywina iindawo zokungqubana kwesinye isiqwenga sobushushu esingaphezulu kunesiqhelo;
2, kunye nenxalenye yempembelelo yesandi sokungcangcazela;
3, ukuqina okufunekayo komonakalo wevalvu yomphunga okanye umonakalo kwivalvu ngokwayo;
4, umonakalo wokuqina kwecompressor yokugcina ebandayo.
Iinxalenye zokungqubana kwesilinda, isitywina se-crankcase shaft kunye neqondo lokufudumeza lebheyari liphezulu kunesiqhelo, lingenziwa ngokuthe ngqo ngesandla okanye ngokungathanga ngqo ngokweqondo lobushushu be-crankcase lubricant compressor yokugcina indawo ebandayo kunye nangokuxhomekeke kwiqondo lobushushu bokukhupha umoya ukuze kuchongwe. Iinxalenye zokungqubana kobushushu ngaphezu kobushushu begumbi lomatshini zimalunga nama-20 ℃ ngaphezulu kobushushu obuthathwa njengobuvumelekileyo.
Okwesibini, inxalenye yokungqubana kwezinga lokufudumeza iphezulu kunexabiso eliqhelekileyo, izizathu eziphambili zezi zilandelayo:
1, ngenxa yokusilela kwepompo yeoyile; ukuvaleka kwesihluzo, umonakalo wokuqina kwenkqubo yokuthambisa, ukuhla kwenqanaba leoyile ye-crankcase okanye ukulungiswa komlawuli woxinzelelo lweoyile akulunganga, njl.njl., kwiindawo zokungqubana kobonelelo lweoyile alwanelanga;
2. I-oyile esetyenzisiweyo ayifanelekanga okanye ayingcolanga kakhulu;
3, xa kuhlanganiswa ezinye iindawo akulunganga, isiphumo sokwakheka komsantsa asanele, okanye kwezinye iindawo akukho msantsa konke konke;
4, itywina leshaft lishushu ngaphezu kobushushu obuqhelekileyo, lisenokuba libangelwa yimpembelelo yoxinzelelo oluphezulu kwi-crankcase yecompressor yokugcina ebandayo. Kule meko, uxinzelelo lweoyile ngaphakathi kwetywina leshaft ludlula kakhulu uxinzelelo lomoya, ngaloo ndlela uxinzelelo lweyunithi yetywina leshaft seal luyanda.
Okwesithathu, izizathu zesandi sempembelelo zezi:
1, iindawo zokungqubana phakathi komsantsa ziyanda ngenxa yokuguga nokukrazuka;
2, umonakalo wesinye isiqwenga (i-valve yomphunga kunye neringi yepiston zihlala zonakele);
3, umthamo wokucoca umgca awanelanga, ngoko ke ipiston ibetha intloko yesilinda okanye ivalvu yokukhupha umoya;
4, i-compressor yokugcina ebandayo icinezelwe ngamanzi, ukuze i-refrigerant yolwelo ingene kwi-compressor yokugcina ebandayo, ibe ngaphezu kwe-cylinder kwi-she clearance volume, ingene kwi-cylinder yamanzi kunye ne-oyile engaphezulu okanye elinye iqhekeza eliqhekekileyo liwele kwi-cylinder;
5, umonakalo weendawo ezinkulu (intonga yokudibanisa, ukususwa kwephini yentonga yokudibanisa, umonakalo we-crankshaft). Ivalvu yomphunga ngenxa yokuguguleka okanye umonakalo obangelwe kukuqina komonakalo, okanye umonakalo wayo, iya kwenza ubushushu begesi yokukhupha umoya. Icompressor yokugcina ebandayo ye-multi-cylinder umonakalo wevalvu yomphunga yesilinda, ingasetyenziselwa ukumisela ngesandla ngokwesilinda kunye nesinye isilinda xa kuthelekiswa nobushushu obuphezulu kunesiqhelo;
6, i-compressor yokugcina ubanda ethe tye inokusekelwe kwi-valve yokufunxa i-valve kwiqondo lokunyibilika kwe-frost maleko ukuze kuqinisekiswe ukuba i-valve yokufunxa ayisebenzi na;
7, iindawo zoqhagamshelo ezinokususwa (intloko yesilinda, i-crankcase, i-valve flange, i-shaft seal) yokukhululeka kwe-refrigerant kunye nokulahleka kweoyile yokuthambisa kunye nomoya ofunxwa kwinkqubo. Ekusetyenzisweni kweefriji ezinetyhefu neziqhumayo ngaphakathi kwesixhobo, ukuvela kokungabikho kokuqina kuya kubangela ityhefu kunye nokuqhuma komsebenzi wengozi.
