Extension laum rods, tseem hu ua extension drill steels, MM rods, yog ib qho ntawm cov khoom siv drilling nrog threaded txuas ntawm ob qho kawg. Nws txuas nrog shank adapters lossis coupling tes tsho thaum ua haujlwm. Nws tuaj yeem txuas lossis tshem tawm hauv cov koob kom ncav cuag qhov xav tau qhov tob tob rau ntev - qhov drilling.
Extension laum rods yuav tshwm sim rau cov teeb meem hauv qab no thaum siv:
1) Cov xov hlau hnav, khaus, ntes. Lub sij hawm ntev - cuam tshuam, torsion, thiab plua plav paug ua rau cov xov nrawm nrawm thiab deformation. Nyob rau hauv cov xwm txheej hnyav, threads txeeb ua ke, ua rau disassembly tsis yooj yim sua thiab ua rau cov khoom ncaj qha.
2) Qws lub cev khoov thiab deformation. Inclined drilling, unbalanced quab yuam, lub pob zeb nyuaj, lossis kev ua haujlwm tsis zoo tuaj yeem khoov tus pas nrig, txo qhov raug drilling thiab cuam tshuam rau kev ua haujlwm ib txwm muaj.
3) Kev tawg. Kev puas tsuaj rau qaug zog, cov khoom siv tsis raug, kev kho cua sov tsis zoo, thiab dhau - cuam tshuam yog qhov ua rau tseem ceeb. Kev tawg feem ntau tshwm sim ntawm cov hauv paus hniav los yog kev ntxhov siab- thaj chaw sib xyaw.
4) Loose los yog poob lub tes tsho coupling. Cov xov tsis zoo haum, tsis txaus xauv, thiab siab - zaus vibration ua rau lub tes tsho xoob, txo lub zog xa mus thiab ua rau cov pas nrig poob lossis jamming.
5) Qhov sib txawv. Tsis txaus tus pas nrig rigidity, tsis zoo ncaj tom qab kev sib txuas, thiab tsis sib xws pob zeb hardness ua rau lub qhov deflection, txo blasting thiab kev tsim kho efficiency.
6) Cov teeb meem dej ntws tawm thiab cov pas nrig jamming. Cov huab cua tsis txaus lossis dej tsis txaus, kev tsim cov pob zeb tawg, lossis lub qhov tawg ua rau cov dej ntws tsis zoo, ua rau hnyav hnyav thiab ua rau jamming.
7) Lub neej ua haujlwm luv. Cov khoom siv tsis zoo, kev kho cua sov tsis zoo, lossis tsis sib haum nrog lub tshuab tho ua rau lub neej ua haujlwm luv.
Txhawm rau zam cov teeb meem zoo li no, cov tho tho yuav tsum nruj me ntsis ua raws li cov thawj coj hauv qab no: A) Xaiv cov rods zoo rau lub tshuab tho. B) Ua haujlwm kom raug. C) Txhim kho kev tshuaj xyuas thiab kev saib xyuas. D) Khaws kom raug kom tsis txhob muaj kev puas tsuaj. E) Xaiv cov khoom siv thiab cov khoom siv txhim khu kev qha.
Raws li ib tug kws tshaj lij Tuam Tshoj extension laum rods tsum, Gdrills tsom rau cov khoom zoo raw xaiv, nruj zoo soj ntsuam, thiab sov so tom qab -muag kev pab cuam los muab cov neeg siv khoom siab - zoo rods. Nrog kev paub nplua nuj, ua tiav cov khoom lag luam, Gdrills muab tus nqi- cov kev daws teeb meem zoo thiab ruaj khov rau cov neeg siv khoom thoob ntiaj teb hauv kev mining, tunneling, quarrying, thiab kev tsim kho vaj tse, ua rau peb muaj kev ntseeg siab ntev ntev - tus khub rau kev ua haujlwm drilling.
