1,Umgomo wokusebenzaI-piston compressor iyisilinda, i-valve kanye nesilinda sokunyakaza okuphindaphindayo kwe-piston okwakhiwa yivolumu yomsebenzi eshintsha njalo ukuze iqedwe. Uma ungacabangi ngomsebenzi wangempela wokulahlekelwa kwevolumu ye-piston compressor kanye nokulahlekelwa kwamandla (okungukuthi, inqubo yokusebenza efanelekile), i-crankshaft ye-piston compressor ngokujikeleza kwesonto ukuze kuqedwe umsebenzi, ingahlukaniswa ngenqubo yokumunca, yokucindezela kanye neyokukhipha umoya.
Inqubo yokucindezela:Uma i-piston isuka endaweni engezansi yokuma iye phezulu, i-valve yokumunca nokukhipha igesi ivaliwe, igesi elisesilinda elivaliwe liyacindezelwa, njengoba ivolumu yesilinda incipha kancane kancane, ingcindezi, izinga lokushisa landa kancane kancane kuze kube yilapho ingcindezi yegesi yesilinda kanye nengcindezi yokukhipha igesi ilingana. Inqubo yokucindezela ngokuvamile ibhekwa njengenqubo ye-isentropic.
Inqubo yokukhipha ugesi: i-piston iyaqhubeka nokunyuka, okuholela ekutheni ingcindezi yegesi yesilinda inkulu kunengcindezi yokukhipha, i-valve yokukhipha iyavuleka, igesi yesilinda episton isunduze ingcindezi iphume kwisilinda iye epayipini lokukhipha, kuze kube yilapho i-piston inyakaza iye esitobhini esiphezulu. Kuleli qophelo, ngenxa yamandla entwasahlobo ye-valve yokukhipha kanye nendima yamandla adonsela phansi e-valve uqobo, i-valve yokukhipha yavala ukuphela kokukhipha.
2, izicelo ze-piston compressor
Izicelo eziyinhloko: imakethe yokugcina ebanda kanye nemakethe yokuqandisa kanye nokufaka esiqandisini kusetshenziswa ama-compressor e-piston angenawo umoya omningi; izicelo ezincane: umoya opholile oqandisiwe webhizinisi.
I-semi-hermetic piston compressor yokugcina ebandayo ivame ukuqhutshwa yinjini enama-pole amane, futhi amandla ayo alinganiselwe ngokuvamile aphakathi kuka-60-600 KW. Inani lamasilinda lingu-2 - 8, kuze kufike ku-12.2, izinhlelo zokusebenza ze-piston compressor
Izicelo eziyinhloko: indawo yokugcina ebanda kanye nefriji kanye nemakethe yokubanda kusetshenziswa i-compressor ye-piston ethambile kakhulu; izicelo ezincane: i-air conditioner yefriji yezentengiselwano.
I-compressor ye-piston ethambilengobaindawo yokugcina ebandayongokuvamile iqhutshwa yinjini enama-pole amane, futhi amandla ayo alinganiselwe ngokuvamile aphakathi kuka-60-600KW. Inani lamasilinda lingu-2 - 8, kuze kufike ku-12.
3, izinzuzo zama-compressor e-piston
(1) Ingcindezi edingekayo ingatholakala kungakhathaliseki ukuthi ingakanani ijubane lokugeleza, ngobubanzi obukhulu bezingcindezi zokukhipha ezifika ku-320MPa (izicelo zezimboni) ngisho no-700MPa, (elabhorethri).
(2) Umthamo womshini owodwa wanoma yiliphi izinga lokugeleza elifika ku-500 m3/min.
(3) Izidingo zezinto eziphansi ebangeni lokucindezela elijwayelekile, ikakhulukazi ezenziwe ngezinto zensimbi ezivamile, kulula ukuzicubungula futhi kushibhile ukuzakha.
(4) Ukusebenza kahle kokushisa okuphezulu, ngokuvamile amayunithi amakhulu naphakathi angafinyelela cishe ukusebenza kahle kwe-adiabatic okungu-0.7 ~ 0.85.
(5) Ukuzivumelanisa nezimo okunamandla lapho kulungiswa ivolumu yegesi, okungukuthi ububanzi bokukhipha umoya bubanzi futhi abuthinteki yingcindezi ephezulu noma ephansi, futhi bungavumelanisa nobubanzi bokucindezela kanye nezidingo zevolumu yokuqandisa.
(6) Ubunzima kanye nezici zegesi azinawo umthelela omkhulu ekusebenzeni kwe-compressor, futhi i-compressor efanayo ingasetshenziswa kumagesi ahlukene.
(7) Umshini wokushayela ulula kakhulu, ikakhulukazi usebenzisa ama-motor kagesi, ngokuvamile awunawo umthetho wejubane, futhi ulungiseka kahle kakhulu.
(8) ubuchwepheshe be-piston compressor buvuthiwe kakhulu, ukukhiqizwa kokusetshenziswa kolwazi oluqoqiwe.
4, izinkinga zama-compressor e-piston
(1) isakhiwo esiyinkimbinkimbi nesibanzi, izingxenye ezigugile, isikhala esikhulu sephansi, ukutshalwa kwezimali okuphezulu, umthwalo womsebenzi wokulungisa, ukusetshenziswa komjikelezo omfushane, kodwa ngemva kwemizamo kungafinyelela emahoreni angaphezu kuka-8000.
(2) Isivinini asiphezulu, umshini mkhulu futhi unzima, futhi umthamo wokukhipha umoya womshini owodwa ngokuvamile ungaphansi kuka-500 m3/min.
(3) Ukudlidliza ekusebenzeni komshini.
(4) Igesi yokukhipha umoya ayiqhubeki, ukugeleza komoya kune-pulsation, okulula ukubangela ukudlidliza kwepayipi, okuvame ukubangela umonakalo kunethiwekhi yamapayipi noma izingxenye zomshini ngenxa ye-pulsation kanye ne-resonance yokugeleza komoya ezimweni ezimbi kakhulu.
(5) Ukulawulwa kokugeleza kwamanzi kusetshenziswa ama-volume noma ama-valve e-bypass axhaswe ngemali, yize elula, elula futhi ethembekile, kodwa ngokulahlekelwa kwamandla okukhulu kanye nokusebenza kahle okuncishisiwe ngesikhathi sokusebenza komthwalo oyingxenye.
(6) Ama-compressor agcotshwe ngamafutha anegesi edinga ukususwa.
(7) Izitshalo ezinkulu ezisebenzisa amasethi amaningi e-compressor uma kunezinjini eziningi noma umfutho wokusebenza uphezulu.
