Advantages, disadvantages and working principle of electric hammer; what are the characteristics of a high-quality electric hammer？？？
Electric tool is a kind of low value consumables, so this kind of electric tools selling hammer. Do you know what kind of hammer? The following details hammer advantages and disadvantages, working principle and a good hammer with which the characteristics of.
一、The advantages and disadvantages of electric hammer
Hammer has the advantages of high efficiency, large aperture and long drilling depth.
Hammer shortcomings: the disadvantage is vibration, damage degree of surrounding structures. For reinforced concrete structures, can not be passed, due to the scope of work, can not be too close to the building.
二、The working principle of electric hammer
Hammer principle is driving mechanism drives the drill bit to do rotary motion and a direction vertical to head reciprocating hammer hammer motion. Hammer is by a transmission mechanism to drive the piston in a cylinder of reciprocating air and cylinder air pressure, periodic change drive cylinder hammer hammer back and forth to hit a brick at the top, if we use a hammer to knock brick, named hammer.
三、What kind of a good hammer?
A good hammer should have what characteristics：
1、Accurate speed control switch：The rotational speed is lower when touching the switch, which can help the machine to pull out of hole stably (for example, when the machine is used to pull out of hole on ceramic tile or other smooth surface, it can prevent skidding, and protect the drill hole from being cracked). When in normal work, the machine can run at high speed to ensure efficiency.
2、Stable and reliable safety clutch ：It also called torque limitation clutch, can prevent from transferring high torque counter-acting force arising from stuck drill bit to users, this is a safety protection for users. Furthermore, it also can prevent gear device and motor from stopping. 。
3、Forward and reverse rotation ：It provides the electric hammer a wider application range, and is mainly realized by a switch or by regulating the position of carbon brush. Famous-brand tools can realize forward and reverse rotation by regulating the position of carbon brush (rotating the brush carrier) generally, which makes operation convenient, effectively inhibits spark to protect commutator, and prolongs the service life of motor.
