Iphethini yokugeleza kwe-compressor encane ye-piston epholiswe ngomoya ingalandelelwa emuva ekuqaleni kwekhulu le-19. Zisetshenziswa kabanzi emishinini ehlukahlukene, umfutho ophezulu ungafinyelela ku-1.2MPa. Amayunithi apholiswe ngomoya anobukhulu obuhlukahlukene angashintshwa ukuze avumelane nendawo yasehlane.
I-compressor encane ye-piston evame kakhulu yi-single-acting. Izinga lokushisa lokukhipha umoya lingafinyelela ku-240°C, futhi umsindo omningi wokusebenza kweyunithi udlula u-80dBA.
Kumayunithi anamandla aphansi, ngoba izindleko zokutshalwa kwezimali zokuqala zingaphansi ngo-40-60% kunezama-screw compressor, ama-piston compressor anenani eliphezulu lokusetshenziswa. Lapha futhi kudingeka sicabangele eminye imishini yokusiza, njenge-cooler yesibili, i-starter kanye ne-shutdown switch, lezi zindleko kufanele zifakwe entengo iyonke.
Ama-compressor amancane e-piston anganikeza umoya ocindezelwe wekhwalithi ephezulu ofanele imishini eminingi isikhathi eside. Umklamo olula, ububanzi bokusebenza kanye nokuthembeka okuphezulu yiwona amandla awo abaluleke kakhulu.
Nakuba ukutshalwa kwezimali kokuqala kwama-screw compressor kubiza kakhulu kune-piston compressors, aya ngokuya ethandwa kakhulu ebangeni lamandla angu-7.4-22kW. Esinye isizathu ukuthi ama-screw unit avame ukupakishwa njengamamojula. Ezimweni eziningi, i-standard screw unit module ipakishwa nge-starter, i-aftercooler, kanye ne-compressor controller enekhono lokuqapha umthamo.
Ama-screw compressor angasetshenziswa futhi ebangeni elincane lamandla, kusukela ku-3.7 kuya ku-22kW. Ngaphansi kwesimo esifanayo samandla, inzuzo eyodwa ngaphezu kwama-piston compressor ukuthi izinga lokushisa lokukhipha kwawo liphansi. I-screw compressor yenzelwe ukusebenza ngaphansi komjikelezo womthwalo ongu-100%, ngamafutha aphansi okugcoba futhi enikeza umoya ocindezelwe wekhwalithi ephezulu.
Faka
Ama-compressor amancane e-piston adinga ukuhlonyiswa ngamathangi okugcina igesi. Ithangi lokugcina umoya lisetshenziselwa ukugcina umoya ocindezelwe nokunciphisa isikhathi sokusebenza komthwalo we-compressor. Amanye ama-compressor amancane e-piston avame ukusebenza ngaphakathi cishe kwama-66% wesikhathi somjikelezo wokusebenza (womthwalo).
Impilo yenjini yepiston enethangi likaphethiloli elikhulu ngokwanele ibaluleke kakhulu. Kungakhathaliseki ukuthi ithangi likaphethiloli lingakanani noma isakhiwo se-compressor kanye nethangi likaphethiloli, ukufakwa kwe-compressor encane yepiston kulula ngaso sonke isikhathi. Ngenxa yamandla angalingani, noma iyiphi i-compressor yepiston kufanele ibekwe phansi.
Amamojula amaningi omshini wezikulufo aklanyelwe ukuba ahambe ngokuzimela, futhi isisekelo sawo sokufakwa singabekwa ngisho naphezu kwethangi likaphethiloli. Akukho ukushaya komoya ekukhishweni kwe-screw compressor. Noma kunjalo, uhlelo oluhlanganisa nethangi lokugcina umoya luwusizo kakhulu ekubuyiseleni isignali yomoya kumlawuli we-compressor kanye nokusebenza okuzinzile kohlelo.
Ama-screw compressor amancane anganikeza abasebenzisi ibhokisi lonke, elingasetshenziswa ezinhlelweni zomoya ezicindezelwe ezidinga ivolumu yomoya engaguquki. Izinga lomsindo wokusebenza kwamayunithi amaningi ezikulufo ezivalekile liphansi kune-80dBA. I-screw compressor epakishiwe ingafakwa kalula phansi, futhi ngokuvamile kusetshenziswa idivayisi yokuxhuma enephuzu elilodwa kuphela ukuxhuma ugesi negesi.
Ukukhetha indawo efanele yokufaka kubalulekile ekuthembekeni nasekuphileni isikhathi eside kwe-compressor epholile emoyeni. Ukugeleza komoya okuhle emzimbeni we-compressor kuyisimo esidingekayo ukuze umshini usebenze kahle futhi uhlale isikhathi eside.
Ngokuvamile, ikhwalithi yomoya ocindezelwe wama-screw compressors ingcono. Ngisho noma kuyiyunithi yesikulufu egcotshwe ngamafutha, isihlukanisi segesi kawoyela esisebenza kahle kakhulu singanciphisa okuqukethwe kwamafutha okukhishelwa ohlelweni lomoya ocindezelwe kube ngu-5ppm. Ngesikhathi esifanayo, izinga lokushisa eliphansi lokukhipha umoya lomshini wesikulufu lingathuthukisa kakhulu ikhwalithi yomoya ocindezelwe. Izinga lokushisa lokukhipha umoya lamayunithi amaningi esikulufu liphakeme cishe ngo-50°C kunezinga lokushisa elizungezile.
