Izicindezi zomoya

Ama-compressor omoya ayindawo ebalulekile kumishini eyengeziwe ekwakheni izisekelo ezijulile, anikeza umoya ophumayo ophakanyisiwe kumasistimu apneumatic abalulekile ekuzinziseni komhlabathi, ukufakwa kwezindonga zokugcina, kanye nemisebenzi yokushintsha umhlaba. Lezi zinhlelo zifaka umoya ophansi ophumelelayo ukuze kukhanyiswe imishini, amathuluzi, kanye nezinqubo ezibalulekile ekwakheni izisekelo ezijulile zanamuhla, ikakhulu ezicini ezihlobene nezindonga zediyafram, amabha ahlukanisiwe, izindonga zokuphuma, kanye nemisebenzi ye-jet grouting. Indima eyinhloko yezinhlelo zokucindezela umoya emsebenzini wezisekelo ezijulile ihlanganisa izindawo eziningi zokusebenza. Ama-hammer apneumatic nama-breakers asetshenziswa durante ekwakhiweni kwezindonga zokugcina kanye nemisebenzi yokuhlanganisa umhlabathi-ne-cement, angadinga ngokuphelele umoya ophumelelayo ophakanyisiwe. Ukwengeza, ama-compressor omoya asebenza njengezinsiza zokucindezela kumasistimu okukhuthaza asetshenziswa ezinhlelweni ezikhethekile ze-grouting, ukunciphisa uthuli ngesikhathi sokuv drilling, kanye nezindlela zokwenza kube lula kumasokisi asetshenziswa ekwakheni izindonga zediyafram. Emtakeni wokuhlanganisa (MIP) nasezinhlelweni zokuhlanganisa umhlaba oguqugquzayo (DSM), umoya ophakanyisiwe uphakamisa imoto ye-pneumatic esebenza kumathuluzi okuhlanganisa futhi u facilitating izinqubo zokushintsha umhlaba ezidinga ukuhlinzekwa okwandisiwe okuphezulu. Izicelo ezikhethekile emaphahleni e-jet grouting nasezindongeni zokugcina umhlaba ne-bentonite zincika kumkhawulo ocacile wokucindezela komoya ukuze kuqinisekiswe ikhwalithi yokwelapha evamile ezindaweni ezahlukene zokujula. Ngokwenziwa, izinhlelo zokucindezela umoya zisebenza ngokuhamba noma izindlela zokucindezela eziphilayo. Ama-compressor e-reciprocating piston, uhlobo olujwayelekile emsebenzini wezisekelo, acindezela umoya ngokomchanjiswa ngesikhathi sokuhlinzeka nokukhishwa, enikeza ucindezelo oluvamile olukhuluma phakathi kuka-7 no-25 bar kuye ngezidingo zohlelo. Ama-compressor e-rotary screw anikeza ukuhamba okuqhubekayo ngokuphumelela okuphezulu kwezokusebenza okuqhubekayo, okujwayelekile ekwakhiweni kokuhlola okuphezulu kanye nemisebenzi yokuhlanganisa. Ama-compressor e-centrifugal, asetshenziswa kancane emsebenzini wezisekelo, anikeza umthamo omkhulu wezicelo ezikhethekile. Zonke izinhlelo zifaka ukuhlinzwa kwamanzi, ukuhluza, kanye nokulawulwa kocindezelo ukuze kuqinisekiswe ukuphila kwemishini nokuphumelela kokusebenza. Izingxenye zokugcina ezibambene zigcina umoya ophakanyisiwe, ziqinisa ukuhlinzeka futhi zikhoshe izincazelo ezivela ekusebenzeni kwamathuluzi apneumatic. Izimo zamadivayisi zihluka ngokuya ngecala lokusebenza. Ama-compressor kagesi aphathekayo (200–600 CFM) afanelekile emisebenzini ephathekayo kanye nezindawo ezinomkhawulo emishini. Izinsiza ezihamba ngogesi (800–2000+ CFM) zisebenza njengezinhlelo eziyinhloko zezimayini ezinkulu. Ama-compressor amabili ahlukanisiwe athuthukisa ukusebenza ngesikhathi sokusebenza okuqhubekayo okudingeka ucindezelo oluqhubekayo. Izingxenye zokuhlukanisa amanzi kanye nezihlungi zemikhiqizo zimele izinhlaka ezibalulekile ezivikela imishini ephasi futhi ziqinisekisa ikhwalithi yomkhiqizo ezinhlelweni zokuhlanganisa eziqhubekayo. Izinkomba zokukhetha ama-compressor omoya zifaka ucindezelo oludingekayo (bar), umthamo wokuhamba (CFM/m³/min), ukutholakala komthombo wamandla, izinkinga zokuhamba ezindaweni, kanye nezidingo zecyclus yezenzo. Abakhi bahlola izindleko zodumo, kuhlanganiswe nezindleko zokuphishekela, izikhathi zokunakekelwa, kanye nokuphindaphindeka kwemishini ezinhlelweni ezibalulekile. Ukucabangela kwemvelo kuphinde kuthinte ukukhethwa kokuhamba edolobheni kwemishini kagesi noma izinhlelo ezinezikhawuzo zokukhishwa. Ukuthembeka nokutholakala kwezinsiza ezindaweni zephrojekthi kuthinta izinqumo zokuhlanza imishini. Izindinganiso ezihlobene ezilawulayo izinhlelo zomoya ophakanyisiwe zifaka i-ISO 8573-1 (ukuhlukaniswa kokuhlanzeka komoya ophakanyisiwe), i-EN 60204-32 (ukuphepha kwamagajethi apneumatic), kanye ne-PED 2014/68/EU (umhlahlandlela wezinsiza zocindezelo). Ukuhlolwa kwemishini ngokwemigomo ye-EN 12622 yokuphepha kwezizinda ezipneumatic kanye nokuhambisana nezikhombisi ze-ATEX (zezimpathe zomoya ezivunguza) kukhombisa lokho okungaba yisixhaso sokuhlanganyela okubalulekile kumphakeli wemishini yezisekelo ezisebenza emakethe ezilawulwayo.
