Key Components and Working Principles of Hydraulic Hammers

A hydraulic hammer, also known as a hydraulic breaker, is a powerful tool used in construction and demolition projects. It is designed to break through tough materials such as concrete, rock, and asphalt. Hydraulic hammers are commonly used in road construction, mining, and quarrying operations. In this article, we will explore the key components and working principles of hydraulic hammers.

The main components of a hydraulic hammer include the housing, piston, cylinder, and tool. The housing is the outer shell that encloses all the internal components. It is made of heavy-duty steel to withstand the high impact forces generated during operation. The piston is a cylindrical component that moves back and forth inside the cylinder. It is powered by hydraulic pressure and delivers the striking force to the tool.

The cylinder is a hollow tube that houses the piston and controls its movement. It is filled with hydraulic fluid, which is pressurized to create the necessary force for the hammer to operate. The tool, also known as the chisel or bit, is the part of the hammer that makes direct contact with the material being broken. It is made of hardened steel to withstand the high impact forces and is replaceable when worn out.

The working principle of a hydraulic hammer is based on the principle of hydraulics. When hydraulic fluid is pressurized, it creates a force that can be used to perform work. In the case of a hydraulic hammer, the pressurized hydraulic fluid pushes the piston forward, which in turn strikes the tool with a high impact force. This force is transmitted to the material being broken, causing it to fracture and break apart.

The hydraulic fluid used in hydraulic hammers is typically oil-based. It is stored in a reservoir and pumped into the cylinder under high pressure. The pressure is controlled by a valve system, which regulates the flow of hydraulic fluid into the cylinder. This allows the operator to adjust the striking force of the hammer according to the requirements of the job.

To operate a hydraulic hammer, it needs to be attached to a carrier machine such as an excavator or a skid steer loader. The carrier machine provides the necessary power and stability for the hammer to function effectively. The hydraulic hammer is connected to the carrier machine through hydraulic hoses, which allow the flow of hydraulic fluid between the two.

In conclusion, hydraulic hammers are powerful tools used in construction and demolition projects. They are made up of key components such as the housing, piston, cylinder, and tool. The working principle of a hydraulic hammer is based on the principle of hydraulics, where pressurized hydraulic fluid creates a force that is used to break through tough materials. Hydraulic hammers are operated by attaching them to carrier machines and using hydraulic fluid to generate the necessary force.
