MING DTH Hammer Processing defect

The hammer piston and cylinder liner are tightly matched, mating length is long, the machining accuracy and surface are smoothness .

This requires a very high for cylinder piston and cylinder liner. If the cylinder can not be guaranteed, piston will be intermittently stuck, or will lift the drill pipe and repair the hammer frequently.

In addition,outer casing rigidity of hammer is also an important factor that limits the service life of hammer. If rigidity is poor, hammer will be deformed due to frequent collision. When the hammer does not work, it is necessary to disassemble and clean hammer, which causing deformation of the outer casing. The deformation of the outer casing will cause stuck to disassemble, which will eventually cause scrapped.
