The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

  • 6 Things about Oil Seals You Need to Know

  • When it comes to maintaining the performance and longevity of your vehicle's engine, one critical component that often gets overlooked is the valve cover gasket. This small yet essential piece plays a crucial role in preventing oil leaks and ensuring that the engine runs smoothly. Over time, exposure to high temperatures and engine oil can cause the gasket to deteriorate, leading to leaks and potential damage to other engine components.
  • Regular maintenance and inspection of oil seals are also critical to ensuring their continued effectiveness. This includes checking for signs of wear or damage, such as cracks or tears, and replacing the seal as necessary. Failure to do so can lead to leaks and other issues that can cause significant damage to the machine and its components.
