1,Umgaqo wokusebenzaI-compressor yepiston yi-cylinder, i-valve kwaye kwi-cylinder yentshukumo yokuphindaphinda yepiston eyenziwe ngumthamo womsebenzi otshintsha rhoqo ukuya kugqityezelwa. Ukuba awucingi ngomsebenzi wokwenyani wokulahleka komthamo we-compressor yepiston kunye nokulahleka kwamandla (oko kukuthi, inkqubo yokusebenza efanelekileyo), i-crankshaft ye-compressor yepiston ngokujikeleza kweveki ukugqiba umsebenzi, inokwahlulwa ibe yinkqubo yokufunxa, yokucinezela kunye neyokukhupha umoya.
Inkqubo yokucinezela:Xa i-piston isuka kwindawo yokuma esezantsi iye phezulu, ivalvu yokufunxa kunye nokukhupha igesi ivaliwe, igesi ekwisilinda evaliweyo iyacinezelwa, njengoko umthamo wesilinda uncipha kancinci kancinci, uxinzelelo, ubushushu bunyuka kancinci kancinci de uxinzelelo lwegesi yesilinda kunye noxinzelelo lokukhupha igesi lulingane. Inkqubo yokucinezelwa ngokubanzi ithathwa njengenkqubo ye-isentropic.
Inkqubo yokukhupha umoya: I-piston iyaqhubeka isiya phezulu, nto leyo ebangela ukuba uxinzelelo lwegesi yesilinda lube lukhulu kunoxinzelelo lwe-exhaust, ivalvu yokukhupha umoya iyavuleka, igesi yesilinda ekwipiston ityhale uxinzelelo luphume kwisilinda luye kumbhobho wokukhupha umoya, de intshukumo yepiston iye kwindawo ephezulu. Kweli nqanaba, ngenxa yamandla entwasahlobo yevalvu yokukhupha umoya kunye nendima yomxhuzulane wevalvu ngokwayo, ivalvu yokukhupha umoya ivale isiphelo se-exhaust.
2, izicelo ze-piston compressor
Iimfuno eziphambili: ukugcinwa kwindawo ebandayo kunye nokukhenkceza kunye nokukhenkceza kwimarike kusetyenziswa iicompressor zepiston ezithambileyo; usetyenziso oluncinci: ukupholisa umoya obandayo kwifriji.
I-semi-hermetic piston compressor yokugcina kwindawo ebandayo idla ngokuqhutywa yimoto enezibonda ezine, kwaye amandla ayo alinganiselweyo ngokubanzi aphakathi kwama-60-600 KW. Inani leesilinda yi-2 - 8, ukuya kuthi ga kwi-12. 2, izicelo ze-piston compressor
Ezona zicelo ziphambili: indawo yokugcina ebandayo kunye nefriji kunye nemarike yokukhenkceza kusetyenziswa icompressor yepiston ethambileyo; ezinye izicelo zincinci: i-air conditioner yorhwebo.
I-compressor yepiston engenantongenxaindawo yokugcina ebandayoidla ngokuqhutywa yimoto enezibonda ezine, kwaye amandla ayo alinganiselweyo aphakathi kwama-60-600KW. Inani leesilinda liyi-2 - 8, ukuya kuthi ga kwi-12.
3, iingenelo ze-piston compressors
(1) Uxinzelelo olufunekayo lunokufumaneka nokuba ingakanani na isantya sokuhamba kwamanzi, kunye noluhlu olubanzi loxinzelelo lokukhupha amanzi ukuya kuthi ga kwi-320MPa (izicelo zoshishino) kunye ne-700MPa, (kwilebhu).
(2) Umthamo womatshini omnye walo naliphi na izinga lokuhamba kwamanzi ukuya kuthi ga kwi-500 m3/min.
(3) Iimfuno zezinto eziphantsi kuluhlu loxinzelelo oluqhelekileyo, uninzi lwazo zenziwe ngezinto zentsimbi eziqhelekileyo, kulula ukuzicubungula kwaye zingabizi kakhulu ukuzakha.
(4) Ukusebenza kakuhle kobushushu obuphezulu, ngokubanzi iiyunithi ezinkulu neziphakathi zinokufikelela malunga nokusebenza kakuhle kwe-adiabatic malunga ne-0.7 ~ 0.85.
(5) Ukuguquguquka okunamandla xa kulungiswa umthamo wegesi, oko kukuthi, uluhlu lokukhupha umoya lubanzi kwaye aluchaphazeleki luxinzelelo oluphezulu okanye oluphantsi, kwaye lunokulungela uluhlu olubanzi loxinzelelo kunye neemfuno zomthamo wokukhenkceza.
(6) Ubunzima kunye neempawu zegesi azinampembelelo ingako ekusebenzeni kwecompressor, kwaye icompressor efanayo ingasetyenziselwa iigesi ezahlukeneyo.
(7) Umatshini wokuqhuba ulula kakhulu, uninzi lwawo lusebenzisa iimoto zombane, ngokubanzi azinawo umgaqo wesantya, kwaye zilungele ukulungiswa.
(8) iteknoloji ye-piston compressor ikhulile ngakumbi, imveliso yokusebenzisa amava aqokelelweyo ivelisa.
4, iingxaki ze-compressors zepiston
(1) isakhiwo esintsonkothileyo nesinkulu, iindawo ezigugileyo, indawo enkulu yomgangatho, utyalo-mali oluphezulu, umthwalo womsebenzi wokulungisa, ukusetyenziswa komjikelo omfutshane, kodwa emva kwemizamo kunokufikelela kwiiyure ezingaphezu kwama-8000.
(2) Isantya asiphezulu, umatshini mkhulu kwaye unzima, kwaye umthamo wokukhupha umoya womatshini omnye ngokubanzi ungaphantsi kwama-500 m3/min.
(3) Ukungcangcazela ekusebenzeni komatshini.
(4) Igesi yokukhupha umoya ayiqhubeki, ukuhamba komoya kune-pulsation, okulula ukubangela ukungcangcazela kombhobho, nto leyo edla ngokubangela umonakalo kuthungelwano lombhobho okanye kwiindawo zomatshini ngenxa ye-pulsation kunye ne-resonance yokuhamba komoya kwiimeko ezinzulu.
(5) Ulawulo lokuhamba kwamanzi kusetyenziswa iivalvu zevolumu ezixhaswayo okanye ezidlulayo, nangona zilula, zilula kwaye zithembekile, kodwa zinokulahleka kwamandla amakhulu kunye nokusebenza okunciphileyo ngexesha lokusebenza komthwalo ongaphelelanga.
(6) Iicompressor ezithanjiswe ngeoyile ezineoyile kwigesi ekufuneka zisuswe.
(7) Izityalo ezinkulu ezisebenzisa iiseti ezininzi zecompressor xa kukho abaqhubi abaninzi okanye ubunzulu bomsebenzi buphezulu.
