Umgomo wokusebenza wesando se-DTH somoya
Njengoba kuboniswe kuMfanekiso 2-5, kunepiston kusilinda.Lapho umoya ocindezelwe ungena ekamelweni eliphezulu lesilinda usuka endaweni yokungena komoya, ukucindezela komoya ocindezelwe kusebenza ekugcineni kwepiston bese kuphusha iphiston liye phansi.Uma ifika endaweni yokugcina Umsila we-drill drill bit, ngesikhathi sokunyakaza okuya phansi kwepiston, igesi endaweni ephansi yegumbi le-cylinder ikhishwa echwebeni lokukhipha.Ngokuphambene, lapho umoya ocindezelwe ungena egumbini elingaphansi usuka endaweni yokukhipha umoya, i-piston iya phezulu, futhi umoya ongaphezulu uyaphuma esikhumulweni sezindiza.Uma isiqondiso sokuthatha kanye ne-exhaust sishintshwa ngokuqhubekayo, ukunyakaza okuphindaphindayo kwepiston kusilinda kungenziwa, ukuze kube nomthelela kaningi emsileni webhithi yokubhoboza futhi kuqashelwe ukusebenza okuqhubekayo kwebhithi lokubhola lomthelela.Ibanga lokuvula lekhodi yokurekhoda yaseMelika (NU-MA) isando somoya we-DTH ngu-89～1092mm, imvamisa yomthelela ingu-1750～925 izikhathi/min, ingcindezi yokusebenza ngu-2.4～1.4MPa;ububanzi bokuvuleka kwesando sasekhaya se-Jiaxing pneumatic DTH singama-85～450mm, futhi imvamisa yomthelela ingu-85–450mm.1200 ~ 840 izikhathi/min, ingcindezi yokusebenza 0.63～1.6MPa.
