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.

El mantenimiento de los chocks es vital para el funcionamiento eficiente de los laminadores. Con el tiempo, el desgaste natural y las condiciones operativas pueden debilitar la estructura de los chocks. Las inspecciones regulares son necesarias para detectar cualquier signo de daño, como grietas o deformaciones. Ignorar el mantenimiento adecuado puede llevar a fallas catastróficas, que no solo provocan tiempos de inactividad prolongados, sino que también pueden resultar en costosas reparaciones y en la pérdida de materia prima.

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.

  • Choosing the Right Oil Seals:

  • An oil seal serves three crucial purposes within any machinery. First, it prevents the leakage of lubricants or fluids outside the seal, even under high pressure. This function ensures the effective operation of equipment, as sufficient lubrication is a key requirement for the smooth functioning of machinery. Second, it retains the lubricating oil within the machinery. This retention function reduces the need for constant maintenance or re-lubrication, saving time and resources. Third, the oil seal acts as a barrier against contaminants. It prevents dirt, dust, and other potential contaminants from entering the machinery, protecting sensitive parts from damage or wear.

  • Shaft surface speed

  • All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.

  • An oil seal is a device used to prevent dirt, dust, water, or any other foreign matter from contaminating shafts and bearings in the rotary shaft equipment. Also known as a shaft seal or dirt seal, it also blocks the leakage of lubricants such as grease and oil along a rotating shaft.

  • There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
