Ama-screw compressor athatha cishe ingxenye enkulu yemakethe yezinhlelo zomoya ezingaphezu kuka-22kW, ngokucindezela okuncane okungu-0.7～1.0MPa. Okuholela kulo mkhuba ukuthuthukiswa kokusebenza kwayo nokuthembeka, kanye nokunciphisa ukulungiswa kanye nezindleko zokuqala eziphansi.
Noma kunjalo, i-compressor ye-piston esebenza kabili iseyiyona compressor esebenza kahle kakhulu. Ukuma kwe-rotor yesikulufu kunciphisa ububanzi bokusebenza kahle kwe-screw compressor. Ngakho-ke, iphrofayili ye-rotor engcono, ukucubungula okuthuthukisiwe kanye nomklamo omusha yizinto ezibalulekile ze-screw compressor.
Isibonelo, i-compressor yesikulufu esinejubane eliphansi, esiqhutshwa ngqo inganikeza ingcindezi yokukhipha engu-0.7MPa kanye nomthamo womoya ongu-0.13-0.14m³, okungu-90-95% we-compressor ye-piston esebenza kabili. Kubasebenzisi abaningi, ngaphandle kwezinye izimo lapho ukusetshenziswa kwamandla kukhulu khona, ngenxa yokutshalwa kwezimali kwayo kokuqala okuphezulu (intengo yokuthenga), i-compressor ye-piston esebenza kabili esebenza kangcono ngokuvamile ayibizi kakhulu ngenxa yesikhathi eside sokukhokha sokutshalwa kwezimali.
I-screw compressor enakekelwe kahle ingasebenza iminyaka eyi-10 noma ngaphezulu. Ngesikhathi esifanayo, uhlelo lwayo lokulawula olunekhono lokuthola amaphutha kanye nokucubungula lungabonisa igebe lokushintsha uwoyela ngokusekelwe ekushiseni kokusebenza, okuthuthukisa nokuthembeka nokuphila kwe-compressor.
londoloza
Ngezindleko zokulungisa, ama-screw compressor anezinzuzo ngaphezu kwama-piston compressor. Ama-piston compressor asebenza kabili anezikhawu zokulungisa ezimfushane kune-screw compressors. I-valve, indandatho ye-piston kanye nezinye izingxenye ezigugile ku-piston compressor zidinga ukulungiswa njalo.
Ukunakekelwa okuyinhloko kwe-screw compressor uwoyela, isihlungi samafutha kanye nesihlukanisi samafutha. Ngezinye izikhathi, ukushintshwa kwemishini yomoya we-screw rotor kanye neyokuhlola kudinga izindleko ezinkulu, kodwa ngokuvamile ingasebenza iminyaka eyi-10 noma ngaphezulu.
I-compressor yesikulufo ejwayelekile inomlawuli osekelwe ku-microprocessor noma kulawulo lukagesi. Laba balawuli bavumela i-screw rotor ukuthi igcine umthwalo isikhathi esingu-100%. Omunye wemisebenzi eyinhloko yomlawuli ukulungisa ukugeleza komoya ukuze umshini ukwazi ukusebenza kahle kakhulu ngaphansi kwezimo zomthwalo ogcwele, umthwalo oyingxenye kanye nokungabi nomthwalo.
Ezinye izilawuli zemishini yezikulufo zineminye imisebenzi eminingi ewusizo yokulawula, njengokuqapha ukusebenza, isixwayiso sokuvala kanye nesikhumbuzi sokulungisa.
Iyunithi ehlonyiswe nge-compressor ye-piston esebenza kahle futhi enakekelwa kahle iwusizo ekusebenzeni. Lolu hlobo lwemishini lungahlanganiswa futhi lusatshalaliswe, kusetshenziswa ukulungiswa nokugcinwa njalo ukuze lube uhlelo lomoya olucindezelwe oluphumelelayo.
ukugcoba
Ngokwezimo ezahlukene zokugcoba, ama-compressor e-piston angahlukaniswa ngezinhlobo ezimbili: agcotshwe kanye nalawo angagcotshwe. Kuyunithi egcotshwe, uwoyela wokugcoba ufakwa kusilinda sokucindezela ukuze kuncishiswe ukungqubuzana phakathi kwesilinda kanye nendandatho ye-piston. Ngaphansi kwezimo ezijwayelekile, indandatho ye-piston egcotshwe kahle ingahlala iminyaka eminingana, futhi ukusetshenziswa kwezinto ezithuthukisiwe kungandisa impilo yendandatho ye-piston kuyunithi yohlobo olomile ibe ngaphezu kwamahora angu-8000.
Izindleko phakathi kwezinjini zepiston ezigcotshwe kanye nezingenawo amafutha ziyisici okufanele sicatshangelwe. Kwezinye izimo, kudingeka umoya noma igesi ecindezelwe engenawo uwoyela. Ukutshalwa kwezimali kokuqala kweyunithi engagcotshwe amafutha kuphakeme ngo-10-15%, futhi akukho mehluko omkhulu phakathi kokusetshenziswa kwamandla kanye nokusebenza kahle. Umehluko omkhulu usekugcinweni okudingekayo kwezinhlobo ezimbili zamayunithi. Izindleko, izindleko zokugcinwa kweyunithi engagcotshwe amafutha ziphindwe kane noma ngaphezulu kuneyunithi egcotshwe amafutha.
Amandla angalingani kanye nesisindo esinzima se-compressor ye-piston yizinto eziyinhloko ezithonya izindleko zokufaka. Ngokuvamile, iyunithi ye-piston idinga isisekelo esinzima kanye nesisekelo esijiyile. Vele, umenzi we-compressor uzohlinzeka ngemininingwane efanele edingekayo ukwakha isisekelo.
Nakuba izindleko zokutshalwa kwezimali zokuqala kanye nokufakwa kwe-piston compressor zingaphezu kwe-screw compressor, impilo ye-piston compressor ngaphansi kokunakekelwa okuhle ingaba yinde ngokuphindwe kabili kuya kahlanu kuneye-screw compressor.
Sekungamashumi eminyaka, i-piston compressor isibe umshini oqinile othembekile. Ngokuthuthuka kobuchwepheshe, ngenkathi inikeza umoya osezingeni eliphezulu, izindleko zokulungisa ama-piston compressor zincishiswe kakhulu. Kumayunithi anomfutho ophansi ongu-0.7 ～1.0MPa, kungakhathaliseki ukuthi umoya ocindezelwe noma amanye amagesi, i-piston compressor iseyisinqumo esingcono kakhulu.
