Work Principles of Demolition Breaker Hammers
A demolition breaker hammer operates on a straightforward yet effective principle. The core mechanism involves a heavy piston that moves rapidly up and down inside a cylinder, driven by compressed air, electricity, or hydraulic power. When the piston strikes the chisel or breaker bit, it generates a powerful impact force that is transferred to the material being broken.
Power Source: Modern demolition breaker hammers can be powered by various sources:
Pneumatic (Air-Powered): These hammers use compressed air to drive the piston. They are widely used due to their high power-to-weight ratio and reliability.
Electric: Electric demolition breaker hammers are powered by an electric motor. They are generally lighter and more portable than pneumatic models but may have less power.
Hydraulic: Hydraulic demolition breaker hammers are often used in heavy-duty applications. They provide consistent power and are suitable for continuous operation.
Impact Mechanism: The piston in a demolition breaker hammer is designed to move at high speeds, typically between 1,000 and 2,000 impacts per minute. The frequency and force of these impacts are crucial for breaking through tough materials. The chisel or breaker bit, which is attached to the end of the hammer, is designed to concentrate the impact force on a small area, making it highly effective for demolition tasks.
Control and Operation: Operators control the direction and force of the demolition breaker hammer using handles and levers. Most modern models come with ergonomic designs to reduce operator fatigue and improve control. Some advanced hammers also feature adjustable impact settings, allowing operators to tailor the power output to the specific task at hand.
