  • Water Well Rig Truck Mounted Drilling - China

    price: contact company for price

    level is much lower than the crawler water well drill rigs hydraulic

    rock drill pneumatic rock drills (pneumatic rock drill 1m distance of

    the sound pressure level of 110db (a) above), but still higher than90db

    (a), up to 100db (a) around, and the sound energy concentrated in the 1

    ~ 5khz frequency segment does not exceed the human ear is sensitive

    frequency range, if not take the well drilling rigs for sale noise

    protection measures body of workers is still harmful. Hydraulic rock

    drill pilot study noise source of the noise generated by the impact

    mechanism broken rock noise, the noise generated by the rotating

    mechanism and drill bits. Noise generated by the impact mechanism

    striking piston solder tail closed space generated jet noise, impact

    structural noise generated after the piston impact solder and is

    deformed due to an down the hole drill rig impact surface is generated

    around the pressure pulse noise, wherein the structure-borne noise is

    the main ingredient noise frequency characteristics of the structural

    vibration frequency consistent. The slewing mechanism noise from the

    slewing mechanism hydraulic and mechanical noise, but the noise

    intensity lower than the noise generated by the impact mechanism, sound

    pressure level difference of more than 10db (a), so little effect on the

    hydraulic rock drill noise evaluation. The drill head broken rock noise

    generated hydraulic rock drill noise test chiseled into the rock drill

    head 0.5m deep, this effect is negligible. Therefore, the research,

    testing and analysis of hydraulic rock truck mounted drilling rig drill

    noise, mainly focus on the noise generated in the shock structure.

    Experimental study on hydraulic rock drill impulsive noise and its

    impact mechanism vibration frequency characteristics test and analysis

    of well drilling trucks for sale hydraulic rock drill noise is mainly

    related to the size of the impact energy and impact frequency has little

    effect. Since under certain conditions, the impact of the hydraulic rock

    drill size depending on the working pressure, to select the appropriate

    working pressure is the key to reduce the noise of the hydraulic rock

    drill. Hydraulic rock drill noise is caused mainly by the structure of

    the noise, the
