Introduction Hammer Hammer Hammer drill is based on the increase driven by an electric motor crank rod piston reciprocating in a cylinder of compressed air, so that the air pressure inside the cylinder was a cycle, changes in air pressure driven cylinder The hammer hit the top of the drill back and forth, as if we are struck with a hammer drill. Named Hammer! zmjt04 Hammer Hammer principle is the principle of the transmission mechanism in driving the rotary motion of the drill at the same time, there is a direction perpendicular to the rotor hammer reciprocating motion. Hammer is driven by the actuator piston reciprocating in a cylinder of compressed air, the air pressure inside the cylinder cycle driven cylinder reciprocating hammer blow in the top of the bricks, as if we are struck with a hammer bricks, named Hammer. Features a hammer, good shock absorption system: allows the operator comfortable grip, relieve fatigue. Approach: The "vibration control system" to achieve; increase by soft comfort grip handle; 2, precise speed control switch: Touch the switch when the speed is low, can help smooth from drilling machine (for example, tiles and other smooth on the surface from the drilling, the drill bit can not only prevent slip, you can also be used to prevent rupture at high speed drilling work to ensure the efficiency of three, reliable safety clutch: Also known as torque limiting clutch to avoid during use large torque reaction force due to catching the drill bit and is transmitted to the user, which is a security protection to the user. This feature also prevents the gear unit and the motor stops rotating. 4, full motor protection apparatus : there will be inevitable in the use of hard particulate matter into the machine (especially for machines up drilling operations, such as drilling on top of the wall), if the motor is not necessarily protective, high-speed rotation can easily be hit hard objects broken or scratched wire, eventually leading to failure of the motor 5, reversing function: Hammer can use a wider range, and its implementation in the form mainly through the switch or adjust the position to achieve carbon brushes, usually big adjustment tool will employ carbon Brush position (rotating brush holder) to achieve benefits of doing so is easy to operate, effectively inhibit spark to protect the commutator and prolong motor life 6, hammer drill dual function of the product have been exported to the United States, France, Canada, Indonesia, Russia many countries Vietnam, Australia, South Korea, Iran, etc., to get the client's praise. due to production batches, depending on the model, the above picture is only for reference, the details can contact our sales staff to carry out specific verification.
