Construction of cylinder diesel hammer

It mainly consists of a hammer body, a fuel supply system, a cooling system, and a starting system.

1. Hammer body

It is mainly composed of guide cylinder 1, upper cylinder 2, lower cylinder 9, upper piston 4, lower piston 11, and buffer rubber pad 17. The guiding cylinder guides the direction of the upper piston when driving the inclined pile, and can also prevent the upper piston from jumping out of the hammer body. The upper cylinder is located between the guiding cylinder and the lower cylinder, serving as the guiding device for the upper piston. The lower cylinder is the working cylinder. Both the upper and lower pistons are working pistons that withstand significant impact forces. During the pile driving process, the upper piston is prone to breakage. The buffer pad is installed at the connection between the piston and the lower cylinder, and its function is to reduce the impact of the upper piston on the cylinder. Inertial lubrication is used between the upper cylinder and the upper piston, while forced lubrication is used between the lower piston and the lower cylinder. The lubricating oil is pressurized by the lubricating oil pump, which is operated by the movement of the lower cylinder.

2. Fuel supply system

Composed of fuel tank 5, filter 6, fuel delivery pipe 7, and fuel pump 8. There are two types of fuel pumps for cylindrical diesel hammers: low-pressure plunger type and high-pressure nozzle type.

The fuel supply can be adjusted by adjusting the lever.

3. Cooling system

The cylindrical diesel hammer releases a large amount of heat energy during operation, causing the temperature of components such as the cylinder and piston to rise. Therefore, it will reduce the viscosity of the lubricating oil, intensify the wear of components, and easily cause premature ignition, which will prevent the pile hammer from working properly. The commonly used cooling systems include water-cooled and air-cooled. The cylindrical diesel hammers produced by German company Delmag are all air-cooled, and small pile hammers are also commonly air-cooled. The cooling method is to install heat sinks outside the water tank. Air cooling structure is simpler and more convenient to use than water cooling, but the cooling effect is better than air cooling.

4. Landing gear

The landing gear of the cylindrical diesel hammer has two main functions: one is to lift the upper piston for starting, and the other is to lift the entire pile hammer.
