Rubber-lined pumps are specifically engineered with an inner lining made of high-quality rubber. This lining acts as a protective barrier between the pump components and the fluids being transferred. The primary reason for using rubber as a lining material is its excellent resistance to abrasion, corrosion, and wear. Compared to traditional metal pumps, rubber-lined pumps can significantly extend the lifespan of pump components, reducing maintenance costs and downtime.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

  • 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.
