Idizayini yevalvu yesando se-DTH inikeza ukusebenza okuthembekile, ukusetshenziswa komoya okuphansi, ukunakekela okulula nokwakha kabusha okunezindleko eziphansi.Isithombe sihlonishwa yiCaterpillar.
Isando se-DTH singama-intshi angu-6 ububanzi futhi saba ngesokuqala ukwethulwa emgqeni womkhiqizo we-DTH.Ngokwenkampani, umklamo wayo wamavalvu uhlinzeka ngokusebenza okuthembekile, ukusetshenziswa komoya okuphansi, ukunakekelwa okulula nokwakhiwa kabusha okungabizi kakhulu. Ngaphezu kwalokho, umklamo we-piston uhlinzeka. impilo ende kanye nokudluliswa kwamandla okuphumelelayo.
Isando singasebenza ngesistimu yomoya ocindezelweyo kuze kufike ku-500 psi. Lokhu kucindezela okwengeziwe emuva, kuhlanganiswe nokugeleza komoya okuhambisanayo okudingekayo, kuveza ukushaywa okwengeziwe ngomzuzu, okuholela emazingeni okungena ngokushesha.
Iphinde inikeze ngemishini yokubhoboza imbobo ephansi.Izingcezu manje seziyatholakala ekucushweni okuningana okuhlukile (amayintshi angu-6.75) kuzinguqulo ezijwayelekile nezinzima ukuze kufaniswe izingcezu nezakhiwo zamatshe kanye nezidingo zomsebenzi.
Izinketho zamabhithi zihlanganisa ukuhlukahluka kwe-carbide shape (i-spherical, ballistic) kanye nokwakheka kobuso (i-concave, flat, i-convex), futhi ilungiselelwe ukumelana nokugqokwa okuphakeme kanye nokuthuthukiswa kwamadwala. hlinzeka ngokungena okukhethekile.
