1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

CFM, or Cubic Feet per Minute, is a crucial metric in assessing the performance of air compressors. It indicates the volume of air that the compressor can deliver at a specific pressure level. The CFM 185 air compressor typically delivers an impressive 185 CFM, making it suitable for a wide range of applications that require substantial air supply. This high CFM rating enables the compressor to power multiple tools simultaneously, effectively enhancing productivity on job sites.

In summary, choosing the right pump for slurry applications is crucial to ensure efficient operation and minimize operational costs. Centrifugal and positive displacement pumps each have their distinct advantages, depending on the specific needs of the slurry being handled. By considering the properties of the slurry, pump material, required flow rates, operating conditions, and maintenance needs, industries can optimize their slurry handling processes for better performance and longevity. Ultimately, the right pump selection can lead to increased productivity and reduced wear and tear in industrial operations.

  • Metal enclosure boxes are the standard choice for circuit breakers. That’s because a conductive metal box is necessary for grounding the control panel. In case of a malfunction of contactors or other electrical equipment in the panel, the fault current can be discharged harmlessly into the ground, avoiding potential damage and injuries.
