The principle of power hammers mainly involves the working mechanism of different types of power hammers. The following are several common power hammers and their working principles:
Gas powered hammer: a hammer mechanism with a hammer body that uses gas power. This type of hammer is driven by gas power and has a hammering function.
Electric hammer: The piston is driven by a transmission mechanism to compress air back and forth in a cylinder. The periodic variation of air pressure inside the cylinder drives the hammer in the cylinder to hit the top of the drill bit back and forth, equivalent to hitting the drill bit with a hammer. This working principle gives the electric hammer the advantages of high efficiency, large aperture, and long drilling depth when drilling holes on hard materials.
Vibration hammer: generates up and down vibrations through the relative motion of two eccentric gears, separating the object being acted on from the surrounding soil layer, reducing frictional resistance, and achieving the purpose of sinking and pulling. It has the characteristics of strong grouting force, good pile sinking quality, durability, few faults, convenient use, strong power adaptability, and low noise.
Pneumatic hammer: Using the principle of aerodynamics, adjust the striking force by adjusting the air supply pressure. There is a strong magnetic magnet inside the pneumatic hammer, and before it moves, the magnetic hammer head is tightly attached to the magnetic substrate. When the three-way solenoid valve is energized and the intake pressure is greater than the magnetic force, the magnetic hammer head quickly detaches from the substrate and impacts towards the bottom; After the impact, the three-way solenoid valve is powered off, the gas inside the product is discharged, and the hammer head is reset.
