Ukusetshenziswa Nokunakekelwa Kwe-Down-the-hole Hammer

1. Okuvamile

Ama-DTH ochungechunge lwe-HD acindezelwe ngomoya ophezulu aklanywe njenge-hammer drill. Nokho, ahlukile kwezinye izimbobo zamatshe, ngokusebenzisa ukusebenza okuqhubekayo phansi ngokumelene ne-drill bit.

Umoya ocindezelwe uholelwa ekubholeni ngamatshe udlula ngentambo yethubhu le-dill. Umoya wokukhipha umoya ukhishwa ngembobo entweni yokubhoboza bese usetshenziselwa ukuhlanza imbobo yokubhoboza. Ukujikeleza kulethwa kusuka kuyunithi yokujikeleza bese amandla okudla avela ekudleni adluliselwa ekubholeni kwe-DTH ngamathubhu okubhoboza.

2. Incazelo yobuchwepheshe

I-DTH dill yakhiwe ngethubhu elincane elide eliqukethe i-impact piston, isilinda sangaphakathi, umsabalalisi womoya, i-check valve. I-sub ephezulu yangempela, enezintambo ifakwe i-spanner slot kanye nentambo yokuxhumanisa kuma-drill tubes. Ingxenye engaphambili, i-driver check, efakwe nentambo, ifaka i-bit shank efakwe i-splines futhi inika amandla okudla kanye nokujikeleza ku-drill bit. Indandatho yokuma ikhawulela ukunyakaza kwe-axial kwe-drill bit. Inhloso ye-check valve ukuvimbela ukungcola ukuthi kungene ku-rock drill lapho umoya ucindezelwe uvaliwe. Ngesikhathi sokubhoboza, i-drill bit idonswa ngaphakathi kwe-DTH futhi icindezelwe ku-drive chuck. I-piston ishaya ngqo ebusweni bokushayisana kwe-shank ye-bit. Ukuphefumula komoya kwenzeka lapho i-bit ilahlekelwa ukuthintana nephansi lomgodi.

3. Ukusebenza nokugcinwa

• I-drive chuck kanye ne-sub ephezulu kufakwe ku-cylinder ngezintambo zesandla sokudla. I-drill kumele ihlale ihlanganiswe nokujikeleza kwesandla sokudla.
• Qala ukufaka ikhola nge-throttle encishisiwe endleleni yokushaya kanye nokudla, vumela i-bit isebenze kancane ingene edwaleni.
• Kubalulekile ukuthi amandla okudla avumelane nesisindo sentambo yokubhoboza. Amandla avela kumoto yokubhoboza adinga ukulungiswa ngesikhathi sokubhoboza, kuye ngesisindo esiguquguqukayo sentambo yokubhoboza.
• Ijubane elijwayelekile lokujikeleza le-DTH liphakathi kuka-15—25rpm. Umkhawulo ophezulu ngokuvamile ukhiqiza izinga elihle kakhulu lokukhiqiza, noma kunjalo, edwaleni elinolaka kakhulu, i-rpm kufanele ibe ukuze kugwenywe ukuguguleka ngokweqile kwe-drill bit.
• Ukuvaleka noma ukugoba komgodi, kungaholela ekubholeni okubambekile. Ngakho-ke kungcono ukuhlanza umgodi ngezikhathi ezithile, ngokwenza ukuvunguza umoya ngebholi yamatshe.
• Umsebenzi wokuhlanganisa uwuchungechunge lomsebenzi lapho i-drill engaphansi kwembobo ingase ibhekane nokungcola, ngokusika kanye nokungcola okuhlukahlukene okuwela phansi emgodini. Ngakho-ke, kwenze kube umthetho, ukumboza njalo ukuphela kwentambo yepayipi lokubhoboza ngesikhathi sokujoyina. Qiniseka nokuthi amapayipi okubhoboza awanazo izingcezu nokungcola.
• Ukubaluleka kokugcoba okulungile kwe-rock drill akunakugcizelelwa ngokweqile. Uma i-greasing ifanele isheshisa ukuguguleka futhi ingaholela ekuqhekekeni.

4. Ukuxazulula izinkinga

Iphutha (1): Ukugcotshwa okubi noma okungenakho nhlobo, okubangela ukwanda kokuguguleka noma ukwehla kwesisindo

Imbangela: Uwoyela awufinyeleli endleleni yokushayisana kwe-rock drill

Ikhambi: Hlola ukugcotshwa, gcwalisa ngamafutha uma kudingeka, noma wandise umthamo we-luboil

Iphutha (2): Indlela yomthelela ayisebenzi, noma isebenza ngomphumela oncishisiwe.

imbangela:

①Ukunikezwa komoya ogobile noma ovinjiwe

②Isikhala esikhulu kakhulu, phakathi kwepiston nesilinda sangaphandle, noma phakathi kwepiston nengaphakathi, noma phakathi kwepiston ne-air distributor.

③Ukushayela kuqhutshwa yi-imparites

④Ukwehluleka kwepiston noma ukwehluleka kwevalvu yonyawo.

Ikhambi:

①Hlola umfutho womoya. Hlola ukuthi izindlela zomoya eziya endaweni yokubhoboza idwala zivulekile.

②Qaqa i-drill yedwala bese uhlola ukuguguleka, shintsha ingxenye egugile.

③Hlubula i-drill yedwala bese ugeza zonke izingxenye zangaphakathi

④Hlubula i-drill yedwala bese ushintsha i-piston ephukile noma ulungise kabusha.

Iphutha(3): I-drill bit elahlekile kanye ne-driver chuck

imbangela: Indlela yokushaya isebenze ngaphandle kokuzungeza ngesandla sokunene.

Ikhambi: Bamba imishini ewile ngethuluzi lokudoba. Khumbula ukusebenzisa njalo ukujikeleza ngesandla sokudla, kokubili lapho ubhoboza nalapho uphakamisa intambo yokubhoboza.
