Iphethini yokugeleza ye-piston compressor encane epholile emoyeni ingalandelelwa emuva ekuqaleni kwekhulu le-19.Zisetshenziswa kabanzi kumishini ehlukahlukene, ingcindezi ephakeme kakhulu ingafinyelela ku-1.2MPa.Amayunithi apholile emoyeni anosayizi abahlukahlukene angashintshwa ukuze avumelane nemvelo yasehlane.
I-compressor encane ejwayeleke kakhulu iyi-single acting.Izinga lokushisa lokukhipha umoya lingafinyelela ku-240°C, futhi iningi lomsindo wokusebenza kweyunithi lingaphezu kuka-80dBA.
Kumayunithi anamandla aphansi, ngenxa yokuthi izindleko zokuqala zokutshala imali zingaphansi kuka-40-60% kunalezo ze-screw compressors, ama-piston compressor anenani eliphezulu lokusetshenziswa.Lapha futhi kudingeka kucatshangelwe ezinye izinto ezisizayo, ezifana nesecondary cooler, isiqalisi kanye neswishi yokuvala shaqa, lezi zindleko kufanele zifakwe enanini eliphelele.
Ama-piston compressor amancane anganikeza umoya ocindezelwe osezingeni eliphakeme wemishini eminingi esikhathini eside sokuphila.Idizayini elula, ububanzi bokusebenza okubanzi nokuthembeka okuphezulu amandla abo abaluleke kakhulu.
Nakuba ukutshalwa kwezimali kokuqala kwama-screw compressors kubiza kakhulu kune-piston compressor, aya ngokuya aduma ebangeni lamandla angu-7.4-22kW.Esinye sezizathu ukuthi amayunithi ngezikulufu ngokuvamile apakishwa njengamamojula.Ezimweni eziningi, imojuli yeyunithi yesikulufa ejwayelekile ipakishwa ngesiqalisi, i-aftercooler, nesilawuli se-compressor esinekhono lokuqapha umthamo.
Ama-screw compressor nawo angasetshenziswa ebangeni lamandla amancane, ukusuka ku-3.7 ukuya ku-22kW.Ngaphansi kwesimo samandla esifanayo, inzuzo eyodwa phezu kwama-piston compressor ukuthi izinga lokushisa lokuphuma kwawo liphansi.I-screw compressor yakhelwe ukusebenza ngaphansi komjikelezo wokulayisha ongu-100%, ngowoyela wokugcoba ophansi futhi inikeza umoya ocindezelwe wekhwalithi ephezulu.
Faka
Ama-piston compressor amancane adinga ukuhlonyiswa ngamathangi okugcina igesi.Ithangi lokugcina umoya lisetshenziselwa ukugcina umoya ocindezelwe nokunciphisa isikhathi sokusebenza komthwalo we-compressor.Amanye ama-piston compressor amancane ngokuvamile asebenza ngaphakathi cishe ku-66% wesikhathi somjikelezo wokusebenza (umthwalo).
Ukuphila kwenjini ye-piston enethangi legesi elikhulu ngokwanele kubaluleke kakhulu.Kungakhathaliseki ubukhulu bethangi legesi noma isakhiwo se-compressor kanye nethangi legesi, ukufakwa kwe-piston compressor encane kuhlale kulula.Ngenxa yamandla angalingani, noma iyiphi i-piston compressor kufanele imiswe phansi.
Amamojula amaningi omshini wesikulufa aklanyelwe ukuthi akwazi ukuhamba ngokuzimela, futhi isisekelo sawo sokufakwa singabekwa ngisho nangaphezulu kwethangi legesi.Akukho ukushaya kwe-pulsation ekukhishweni kwe-screw compressor.Noma kunjalo, uhlelo oluhlanganisa ithangi lokugcina umoya luzuzisa kakhulu ukubuyisela kahle isignali yomoya kusilawuli se-compressor nokusebenza okuzinzile kwesistimu.
Ama-screw compressor amancane angahlinzeka abasebenzisi ngebhokisi lonke, elingasetshenziswa ezinhlelweni zomoya ezicindezelwe ezidinga umthamo womoya ongashintshi.Izinga lomsindo elisebenzayo lamayunithi amaningi ayisikulufu avalelwe lingaphansi kuka-80dBA.I-compressor yesikulufu esipakishiwe ingafakwa kalula phansi, futhi ngokuvamile kusetshenziswa idivayisi yokuxhumana enephoyinti elilodwa kuphela ukuxhuma ugesi negesi.
Ukukhetha indawo yokufaka efanele kubalulekile ekuthembekeni nasekuphileni ende kwesevisi ye-compressor epholile emoyeni.Ukugeleza komoya okuhle emzimbeni we-compressor kuyisimo esidingekayo ukuze usebenze kahle nempilo ende yomshini.
Ngokuvamile, ikhwalithi yomoya ecindezelwe ye-screw compressors ingcono.Ngisho noma kuyiyunithi yesikulufu esigcotshwe uwoyela, isihlukanisi segesi kawoyela esisebenza kahle kakhulu singanciphisa okuqukethwe kukawoyela okukhishelwe kusistimu yomoya ecindezelwe ibe ngu-5ppm.Ngasikhathi sinye, izinga lokushisa eliphansi le-screw ngokwemvelo lomshini wesikulufa lingathuthukisa ikhwalithi yomoya ocindezelweyo.Izinga lokushisa lokukhipha umoya lamayunithi amaningi ngezikulufu licishe libe ngu-50°C ngaphezu kwezinga lokushisa elizungezile.
