Mapangidwe apadera a dth hammer

Jenereta ya torque ya nyundo ya dth imagwiritsidwa ntchito molumikizana ndi kubowola kwa PDC.Njira yothyola mwala imatengera kuphwanya kwamphamvu ndikuzungulira ndikumeta miyala.Ntchito yayikulu ndikuwonetsetsa kuti chitsimecho chikuyenda bwino ndikuwongolera liwiro lobowola makina. The torque impactor imachotsa kugwedezeka kumodzi kapena zingapo (zodutsa,

Longitudinal ndi torsional) zochitika zomwe zingachitike pakuyenda kwa pobowola pansi, zimasunga makokedwe a chingwe chonse chobowola kukhala chokhazikika komanso chokhazikika, ndipo mochenjera amasintha mphamvu yamadzi am'matope kukhala torsional, high-frequency, uniform and khola makina mphamvu ndikutumiza mwachindunji ku PDC kubowola pang'ono, kotero kuti kubowola pang'ono ndi pansi pa chitsime nthawi zonse kumapitilirabe.

Zochita za DTH hammer:
1) Nyundo yamtundu wa dth idapangidwa ndi makina owombera mwamphamvu, omwe amatha kugwiritsa ntchito mpweya wothamanga kwambiri potulutsa slag.
2) Idapangidwa ndi pulagi yowongolera mpweya, yomwe imatha kusintha mpweya womwe umagwiritsidwa ntchito potulutsa slag molingana ndi kuuma kosiyanasiyana kwa thanthwe, kukana kuvala, komanso kubowoleza kuti akwaniritse bwino kwambiri kutulutsa kwa slag ndikukwaniritsa bwino kwambiri kubowola.
3) Kapangidwe kake ndi kophweka, pali magawo ochepa, ndipo kugwiritsa ntchito zida zosagwira ntchito kumapangitsa kuti nthawi yogwira ntchito ya dth nyundo ikhale yayitali.
4) Cholumikizira chakutsogolo chimatenga ulusi wokhala ndi mitu yambiri kuti ulumikizane ndi silinda yakunja, kupangitsa kuti nyundo ya dth ikhale yosavuta kusokoneza pobowola.

Kuchuluka kwa kugwiritsa ntchito nyundo za dth:
Migodi, ma quarries, misewu yayikulu ndi ntchito zina zimabowola mabowo ophulitsa, mabowo otchinga, kulimbitsa mapiri, ma nangula ndi mabowo ena aumisiri, mabowo owongolera mpweya wa geothermal, mabowo amadzi, ndi zina.

Pamene nyundo ya dth ikugwira ntchito bwino, kubowola kumatsutsana pansi pa dzenje, ndipo mphamvu ya nyundo ya dth kuchokera ku pistoni imaperekedwa mwachindunji pansi pa dzenje kupyolera mu kubowola. katundu wokhudzidwa.Nyundo ya dth ikakweza chida chobowola, sichilola kuti chipika cha silinda chitha kupirira katundu wokhudzidwa.Kuphatikiza apo, mawonekedwewo ndi othandiza ndipo amatha kupindula ndi nkhonya. Izi ndichifukwa choti kubowola ndi pisitoni kumatsika ndi kulemera kwawo kwa mtunda wina, ndipo kuphulika kwa chitetezo cha mpweya kumawonekera, kotero kukakamizidwa kochokera kumakina owongolera kumayambitsidwa. kulowa mu silinda block, ndi orifice chapakati pa kubowola biti ndi pisitoni kuthawira mu mlengalenga, kuchititsa dth nyundo kusiya kugwira ntchito palokha.
