What is a pneumatic drill?

The pneumatic drill is a type of large, hand -powered hand drill used for disintegration or digging on hard surfaces such as concrete. Pneumatic drills are also called jackhammers, used primarily for construction and rescue work. As the term "pneumatic" indicates, these drills rely on air pressure, which provide them with air compressors driven diesel to move their drill pieces up and down. Pneumatic exercises often require training for use and should only be used by experts.

The pneumatic drill is formed by an outer cover, a handle, thick hoses that connect the drill to the air compressor and the drill bit that starts inside the cover and can be changed depending on the task. Inside the housing are also a simple network of pipes, valve and pile driver. The pressure air is pumped over the hoses into the inner tube tubes. The pilot driver, the heavy metal rod, lifts or falls depending on the air pressure into the tube, repeatedly hit the drill bit and forces IT tocountry. The air flow is controlled by a valve that alternately blocks one of the two tubes depending on its position.

The process begins when the bore operator presses down on the handle. This allows high -pressurized air from the compressor to push the drill. This high pressure pushes the pilot driver down the tube and hits a drill bit, which is then forced to the ground. The impact of the drill in combination with vibrations created by two hard surfaces encounters force, causing the valve to switch positions, blocking the other tube and moving in a different direction. The air then forces the pile driver back up, causing the valve to re -switch the position and the process is repeated.

Pneumatic exercises are very effective. SDAGEHAMMER can hit the ground five or ten times every minute, but a pneumatic drill bit can hit the ground of 25 time in a second. At 1,500 interventions every minute creates pneumatic drills forceLU, which allows their operators to break large pieces of concrete in seconds.

For this reason, pneumatic exercises are also very noisy and operators must wear hearing protection. In addition, the severity of vibration requires a solid adhesion and strength for hammer control. Too much time to work with a pneumatic drill can cause a carpal tunnel or negatively affect the circulation of the shoulders.
