Iyo torque inokanganisa jenareta ye dth sando inoshandiswa pamwe chete nePDC drill bit.Kutsemuka kwedombo kunoenderana nekupwanya uye kutenderera kugera kuumbwa kwedombo.Basa guru ndere kuona kunaka kwemuviri wetsime uku uchinatsiridza kukurumidza kudhiraivha.Iyo torque impactor inobvisa imwe kana kupfuura vibration (transverse,
longitudinal uye torsional) zviitiko zvinogona kuitika panguva yekufamba kweiyo downhole drill bit, inochengeta torque yetambo yese yekuchera yakagadzikana uye yakadzikama, uye nehungwaru inoshandura simba remvura yematope kuita torsional, high-frequency, yunifomu uye yakagadzikana mechanical impact. simba uye rinoendesa zvakananga kuPDC drill bit, kuitira kuti chibooreso uye pasi petsime nguva dzose zvichengetedze kuenderera.
DTH sando chigadzirwa maficha:
1) Iyi mhando ye dth sando yakagadzirwa ine yakasimba kuvhuvhuta system, iyo inogona kushandisa ese akakwira-kudzvanywa magasi ekuburitsa slag.
2) Yakagadzirwa iine air regulating plug, iyo inogona kugadzirisa mhepo inoshandiswa kuburitsa slag zvinoenderana nekuoma kwakasiyana kwedombo, kupfeka kuramba, uye kudhiraivha kuti uwane yakanakisa slag discharge mhedzisiro uye nekudaro kuwana yakanyanya kuchera.
3) Chimiro chacho chiri nyore, kune zvikamu zvishoma, uye kushandiswa kwezvikamu zvisingapfekeki kunoita kuti nguva yekushanda yedth nyundo irebe.
4) Mubatanidzwa wepamberi unotora shinda-yemusoro yakawanda kuti ibatane neyekunze humburumbira, zvichiita kuti zvive nyore kuti dth nyundo iparadze chibooreso.
Chikamu chekushandiswa kwesando dzedth:
Migodhi, zvicherwa, migwagwa mikuru uye mamwe mapurojekiti anochera makomba anoputika, makomba anovhara, kusimbiswa kwemakomo, anchoring uye mamwe makomba einjiniya, makomba emhepo emhepo, makomba emvura, nezvimwe.
Kana iyo dth nyundo ichishanda zvakajairika, chibooreso chinopesana nepasi pegomba, uye iyo dth nyundo simba kubva papiston inotumirwa zvakananga kuzasi kwegomba kuburikidza ne drill bit. Pakati pavo, cylinder block haimiri. the impact load.Apo dth sando inosimudza chigadziro chekuchera, haibvumiri cylinder block kuti irambe iine simba.Uyezve, chimiro chinoshanda uye chinogona kuwanikwa nekurova.Izvi imhaka yekuti chibooreso uye piston inotsvedza pasi nehuremu hwayo kune imwe chinhambwe, uye kuputika kwekudzivirira kwemhepo kunoburitswa, saka kudzvanywa kubva pakurongeka kunoiswa. mucylinder block, uye nepakati orifice yechibooreso uye piston inopukunyuka ichienda mumhepo, zvichiita kuti dth hammer imire kushanda yega.
