Ukuziqonda Izindlebe Zokungcola Kukhuniwa Kwesawu Yediamond

Izindlebe Ezikhulu Zokungcola Kukhuniwa Okuphakade Ngaphandle Kwediamond

Ukungcola kusuka kusindvo esithathu uma usebenzisa izibhobho zomgwa wodiamond. Okokuqala kukhona uhlangano lwasebenzini phakathi kwebhobho nemongo, okwenzeka kungenza amazwi angama-80 ukuya ku-110 decibels. Emva koko sithola indiza yesithombe njengoba ibhobho iyaphakama kakhulu, ikhiye ngaphezulu kwamadecibels angu-95 uma ivalela i-4,000 RPM. Kwanokugcina kukhona ukuthembekayo okuphindaphindwa futhi kwenza izinkinga zokuxhasana. Uma izibhobho zicubungula kakhulu kunama-35 emeta ngosikhashana, wonke lokhu kuhlanganisa kuhlela kusebenza ngendlela engabi noma yini. Izigaba ze-diamond zihambe nemongo zenza izinketho ezimfushane zamazwi angama-1 ukuya ku-5 kilohertz. Ngasikhathi esifanalo, indiza yokuzijijela iyophaka kwi-bhobho eyodwa, iyenza iphinde iphinde kakhulu. Lokhu kugcina kwenza ukuthi kube luhlaza kakhulu kunesidingo lokusebenzisa okunye ngokwesilinganiso kuphela.

Umxheshana Phakathi KweThembeko LeBhobho Nenkulumo Ye-Acoustic

Umbuzo ubonakala ukuthi kukhona uxabiso oludlulililo phakathi kwegcobo le-thembeko kwebhobho nezilinganiso zomculo:

Amandla okudlidliza	Umbiko wesikrini	Umsebenzi Womculo (dBA)
0.05 mm	800–1,200 Hz	82 ± 2
0.12 mm	2,000–3,500 Hz	94 ± 3

Lokhu kuchazwa ngokuthi izikhuthazo ezinezinhliziyo eziphathelene zihamba ngendlela efanelekileyo kumoya, kepha izikhathi eziphezulu kakhulu zizohlwaya ukuthi ziyehlukene kakhulu. Ngakho-ke ukulawula okungcono kokuvila kufuneka kube yisidingo sokuzimisa isimo.

Ukumelela Ukuvila Emasimini Angempela Ngasebenzisa Izixhobo Ezivumelekileyo Kwe-OSHA
