What are the performance requirements of hydraulic rock drill water seal?
The working condition of the rock drill is more complicated. The drill tail has both axial movement under the impact of the piston and rotation under the action of the motor. At the same time, due to the long drill rod, the drill has a certain degree of swing.
The working condition of the rock drill is more complicated. The drill tail has both axial movement under the impact of the piston and rotation under the action of the motor. At the same time, due to the long drill rod, the drill has a certain degree of swing. The water seal is in a state of composite wear caused by strong impact, high-frequency axial jitter and rotation. It is required that the water seal material must have high mechanical properties such as tensile strength, hardness, tear strength, resilience, wear resistance and hydrolytic stability. Indicators.
