Hydraulic hammers like the Yutani MD120 rely heavily on the hydraulic system of the host excavator to operate. The Kobelco K905A and similar machines use complex hydraulic piping setups to ensure the hammer gets a consistent supply of hydraulic oil at the correct pressure and flow rate.
Components of the Hydraulic Piping System:
- Hydraulic Pump: The pump delivers pressurized oil to the hydraulic hammer. The flow rate must be balanced to provide adequate power to the hammer without causing overpressure or inefficiency.
- Hoses and Pipes: These carry the hydraulic fluid from the pump to the hammer. The size, material, and length of the hoses or pipes can affect the system’s efficiency. If the pipes are too long or of the wrong size, the flow can be restricted, reducing the hammer’s effectiveness.
- Control Valve: A control valve regulates the flow of hydraulic fluid to the hammer, enabling the operator to adjust the impact force. It is crucial to ensure that the valve is calibrated correctly for the specific hammer being used.
- Filters: Hydraulic filters are essential for keeping the fluid free of contaminants. Any debris or dirt in the hydraulic fluid can damage the pump, control valves, and hammer components. Regular maintenance of the filters is essential to prolong the life of the entire system.
Proper installation of the hydraulic piping for the Yutani MD120 hammer is critical for optimal performance. Misaligned pipes or improper connections can lead to leaks, inefficient operation, or even damage to the hammer and excavator. Below are some essential steps for installation and maintenance:
