Down - {{1}- Lub qhov rauj tau siv ntau zaus, hauv paus engineering, thiab kev tshawb nrhiav thiab geological. Powered los ntawm compressed huab cua lossis cov hluav taws xob, lawv cuam tshuam cuam tshuam lub zog tawg pob zeb thiab ua tiav kev ua haujlwm zoo. Raws li ib qho kev sib xyaw ua ke ntawm down {4 4}}- lub qhov cub ua haujlwm hauv kev txhim kho kev siv hluav taws xob thiab kom muaj zog siv hluav taws xob.
Hais txog ntawm lawv txoj kev ua haujlwm, cia {{}} qhov kev ua kom muaj zog ntawm lub zog ntawm lub zog, uas ncaj qha ua rau cov laum me me los tsoo lub pob zeb. Lawv cov qauv feem ntau suav nrog cov khoom tseem ceeb xws li lub piston, valve thaiv, kheej kheej, txhua yam ua haujlwm sib xyaw ua ke ntawm kev cuam tshuam lub zog. Ua raws li cov tsav tsheb nruab nrab, qis -- lub qhov rauj tuaj yeem faib ua pneumatic thiab ntau hom. Pneumatic Hammers yog cov kev xaiv tseem ceeb vim lawv qhov kev yoog tau thiab yooj yim ntawm kev saib xyuas.
Hauv kev thov engineering, kev ua yeeb yam ntawm nqes - {1} {1} {1} {1}- lub qhov cub rauj thiab tus nqi. Siab - rauj rauj yog tsim rau cov chaw ua haujlwm nyuaj pob zeb, thaum tsawg} cov qauv qis yog qhov haum ntawm cov pob zeb muag lossis xoob xoob. Tsis tas li ntawd, cov tsis muaj xws li cuam tshuam ntau, lub zog tso tawm, thiab coj kev ua haujlwm tsis zoo rau kev pabcuam lub neej thiab txo qis hauv qab rau kev saib xyuas. Nyob rau hauv xyoo tsis ntev los no, nce qib nyob rau hauv cov ntaub ntawv science thiab kev tsim khoom siv rau cov impression tungsten steel olds thiab kev txhim kho saum ntuj hardening durability thiab lub zog txuag.
Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm ntse thiab txhais cov thev naus laus zis, thiab kev tswj hwm lub taub hau ntxiv, muab kev txhim kho ntau dua rau kev txhim kho hauv av thiab cov peev txheej kev txhim kho.
