Noise Treatment of Hand - held Rock Drill

Author:kaishan Time:2017-01-06

Hand-held rock drill noise is a very tangled problem, I think a lot of friends in use will have this feeling, today hand-held rock drill manufacturers - Hill Electrical, here for everyone to say on hand-held rock drilling machine noise, First take everyone to see the hand-held rock drill machine noise is from there, and then for noise exclusion.
Hand-held rock drilling machine noise comes mainly from the work of four aspects:
1) noise generated by exhaust gas discharge.
2) noise generated by the impact of the piston hit the drill tail.
3) the impact of the rock drill caused by various components and the drill rod vibration.
4) Rocks subjected to impact.
The above-mentioned several kinds of noise, the comprehensive management method is to use the tubular muffler to wrap the whole hand-held rock drill, so not only eliminate the exhaust noise, but also to avoid the solid noise (ie rock drilling machine noise reflection sound), even the piston hit the drill tail Noise is no longer spread, and can be reduced. Another method is to use the fiber to prevent the sound of the body wrap, the sound-absorbing material to consume sound energy.
