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.

  • In conclusion, metallic oil seals are vital components in numerous industrial processes due to their durability, temperature resistance, and compatibility with a variety of fluids. They not only contribute to the efficiency of machines but also to the overall safety and sustainability of operations. As technology advances, the development of more advanced metallic oil seals will likely further enhance their performance, making them an indispensable element in the future of engineering and manufacturing.

  • ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.

  • Oil tank gaskets are typically made of rubber or other flexible materials that can withstand the high temperatures and pressures that are present in an oil tank. They are designed to create a tight seal between the tank and its components, such as the lid or access port, to prevent oil from escaping and causing a mess or posing a safety hazard.
  • Moreover, silicone oil seals exhibit excellent resistance to ozone, weathering, and aging, which significantly extends their service life. They are also resistant to a variety of chemicals, making them suitable for use in harsh chemical environments. In the medical and food industries, where hygiene is paramount, silicone oil seals are preferred due to their non-toxicity and ease of cleaning.
  • The versatility of round gaskets is truly remarkable. They can be found in a wide range of industries, from automotive to aerospace, from plumbing to power generation. In the automotive industry, for example, round gaskets are used to seal engine blocks, transmission cases, and exhaust systems, ensuring that fluids and gases remain where they belong. In the aerospace industry, they are used to prevent leaks in fuel tanks and hydraulic systems, which is critical for safe flight.
