The inner cylinder plays the role of guiding and bearing the impact force. The material and structural design of the piston and inner cylinder have a crucial impact on the performance and life of the impactor.
Structural features of DTH hammer
Piston and inner cylinderPiston and inner cylinder are the core components of the DTH drill bit impactor. The piston reciprocates in the cylinder to generate impact energy. The inner cylinder plays the role of guiding and bearing the impact force. The material and structural design of the piston and inner cylinder have a crucial impact on the performance and life of the impactor.Gas distribution seat and valve plateGas distribution seat and valve plate are the control components of the down-the-hole drill bit impactor. The gas distribution seat is responsible for introducing compressed air, while the valve plate controls the flow direction of compressed air and the size of the impact energy. The structural design of the gas distribution seat and valve plate can affect the reversing accuracy and impact force of the impactor, thereby affecting the drilling quality and efficiency.Variation designVariable diameter design of the DTH drill bit impactor is its unique structural feature. This design can reduce the resistance of the drill rig when gravel and soil are stuck during drilling, and effectively reduce the probability of failure of the impactor to be lifted. The taper of the variable diameter design can be adjusted according to different working conditions, making the DTH drill bit impactor more suitable for drilling operations in various complex environments.
