Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.

  • 3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm. The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards

  • In the world of agricultural machinery, the rotavator, also known as a tiller, is an indispensable tool for soil preparation. It helps break up and loosen the soil, making it ready for planting. However, the efficient functioning of this equipment heavily relies on a critical component - the oil seal.
  • In conclusion, E3 2022 served as a platform for showcasing the future of spark plug technology. From advanced materials and AI integration to potential applications in electric vehicles, the innovations presented at the event point towards a more efficient, reliable, and environmentally friendly future for the automotive industry.
  • In HVAC systems, 40mm rubber gaskets are used in ductwork and ventilation systems to seal joints and seams. These gaskets help improve energy efficiency by preventing air leaks, ensuring that heated or cooled air is distributed evenly throughout the building. The flexibility and resilience of rubber make these gaskets easy to install and maintain, saving time and money on repairs and replacements.
  • Perhaps one of the most significant advantages of cork rubber gaskets is their eco-friendliness. Cork is a renewable resource that is harvested from the bark of cork oak trees, which are grown in sustainable forests. In addition, cork rubber gaskets are typically made using non-toxic materials, making them an environmentally friendly alternative to other types of gaskets.
  • Replacing a power steering oil seal is a relatively straightforward process for a trained technicianpower
  • Oil

  • In conclusion, oil seals are essential components in machinery and equipment that play a critical role in preventing oil leaks and ensuring smooth operation. The 65x90x10 oil seal, with its specific size and design, offers reliable sealing performance for a wide range of applications. By selecting the right size, material, and design, and following proper installation and maintenance procedures, operators can effectively protect their equipment and prolong its service life.


  • A square rubber gasket is a vital component in various mechanical applications, providing a seal between two surfaces to prevent leakage or contamination. These gaskets are commonly used in machinery, engines, piping systems, and automotive applications.
