Ubucwebo Basebenzayo Obungaphansi Kwemishwa Yokuphendula: Ubucwebo Obumandla Bakhothazwa Komkhiqizo

Ubucwebo Besono Obulindeleke Kabusha (ANSI Z87.1+) Nokuhlanganiswa Kwekheshi Yonke Yomzimba

Xa izikithi ze diamond saw zizala kune-10,000 RPM, zingasabela izinxenye zemetal njengalokhu 300 miles per hour okwakhiwa kakhulu imiphumela engcono. Izicathulo ezivikelekileyo eziqinisekisiweyo ANSI Z87.1+ zizokulahla iindlela eziphakathi kwe-steel engu-quater inch ezihamba ngama-150 feet per second, kodwa lezo azifanele ukuvikelwa xa kusekelwa kwizixhenxe ezikhulu evela kwi-blades ezivilekileyo noma i-hard alloys ezitshondayo. Ngokuvikela kwasebenzayo, abasebenzi bangadinga icibonga epheleleyo engungethu 0.1 inches ebekwe ku-polycarbonate. Le cibonga inakekela both heat nakanye impact, ibuyisela leso sihlangu esikhazimula ekufeni elineminyaka engu-2,000 degrees Fahrenheit. Ize zibonise ukuthi izicibongo zilahlaza imphumela yezono ngaphansi kwesono nge-92% kunokuba usebenzisa kuphela izicathulo. Kanti ngoba ukusebenzisa isitya ne-cast iron kwenza izinto ezibomvu ezingu-30% kunazo onke amayeza, akukho muntu ofanele ahlaselani ngaphandle kokuvikela isono esifanelekileyo endaweni.

Ukukhuseleko Kwezindlela NRR 25—30 dB: Ukwehluleka Kwesivimba Sokuphazanyiswa Kwemoto

Xhoba lapho i-diamond blades zikhipha ngemitholimba ezigcwele, umgqigqo wokuzukulula kwenza amalangwe amaningi ngaphezulu kuka-115 dB, okhangele kakhulu kune-85 dB okuthathazwa njengesivinini ngu-OSHA. Fikrishini ukuthi usemnye wokuthuma kwe-jet engine - lokhu kuyiliphi amalangwe amaningi. Ngokwesiqiniseko sase-CDC/NIOSH wokweminyaka engu-2023, ukusebenzisa i-earmuffs ezilungile ezitholakala ngokuthola amalangwe amaningi okukhupha kuka-25-30 dB angakhusela ukuthola kwamanje kuze kube ngama-82 dB noma ngezansi ngexesha elijulile lokukhipha i-steel elilima ngokungafutshane ngemizuzu engu-15. Oku kuthatha i-aluminum ngendlela eyahlukile. Ngokungathi kunezici zokulawula, kakhulu kwenza le mitholimba yobude obuphakathi kakhulu ngokungafutshane kuka-8-12 dB. Lokhu kakhuthaza amandla okuthi kungekho mntu ayithola ingqondo yoko ngokungafutshane kumva. Kulolu daba, abasebenzi kufuneka bafundze ukusebenzisa ukuphepha okubini - ukufaka i-foam earplugs ngapha kwe-earmuffs. Akukho mntu amandla ukulweseka lolu hlobo ngexesha lonke, kodwa xa usebenza ne-aluminum ngokukhipha okungaphezulu kuka-120 meters ngosekhiye, kuyakha kakhulu ukuphepha kwezivinini.

Imiphakathi Emikhulu Yemetal Ethelela Imfoko Lethulwa Ngaphezu Kwesivinini Esikhulu

Ukugayezeka Kweblade Nokuphazanyiswa Kwethulwa Ngaphezu Kweminyaka Engama-10,000 KuSteel NaseAluminum

Xa izimoto ze-diamond zizuma kusuka kwi-10,000 RPM, zizama izinhliziyo eziphakeme kakhulu kune-20,000 Gs okwenzela ukuthi ubunzima bokwakha kube ngcono uma kudityaniswa ngezinhliziyo zeqobo. Ukugcina isiteleyi kuyenza izimo zibe phezu kwezingu-500 Fahrenheit ngokushesha, lokhu kukhupha ukuqhagamshelwa phakathi kwezinkinga ze-diamond neqanda lesteeli. Izinto ziyaphilisa kangcono nge-aluminium ngoba libeka iqobo ngokushesha, kwenza iqobo elibuthakathaka elivame ukusabalalisa izimoto ngokushesha. Sigabona izilingo apho izimoto eziphulayo zithumela izici zihlelela ngokushesha kangcono kune-180 imitha ngosuku, ngokushesha kungethuli lenziwa yi-.357 magnum, futhi lezi zici zingasebenza njengoko ziqhamuka kwezimali ezijwayelekileyo. Kumele kube khona izixhobo zokuphepha, ngalesikhathi ke ngabe i-face shields enconyelwe ngu-ANSI nakho ne-goggles ebomvu yepolycarbonate ayizalwandle kodwa zikumele kube khona. Bese bangemaqashi onke ukufaka uhlobo lwe-infrared yokulandela izimo zeqobo ngokuxhaswa nezinhlelo zokulima, kanti le zinhlelo zibiza izimo eziphulayo ngokungu-2/3. Le ayizingcinwa zonke, kepha zisahluko esibalulekile sokuphepha okumele kube khona kuwo wonke umsebenzi.

Imikiniso Yekhishisi Namaqondo Okuvula KweSpark KwiZisekelo Zokusebenza Kwesilisa Ngaphandle Kwesilisa

Ukuthukwa kwezimpendulo kubaluleke kakhulu ekukhetheni uhlosi oluthile lwezimvu esiyakuphakathi. Fula izimpendulo ezinezamagugu njengezamagugu zomoya, zibangela izinkuni ezihlupheleyo zezimvu zomoya zazitholakala ezinkunini ezingaphezu kuka 2000 degrees Fahrenheit. Lezi zinkuni zihlanzekile zingakhiqa izinkuni ezivuthiwe ngaphakathi kwezintathu ezingu-10 ezindaweni ezizoluthola.
