  • 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

Regular inspection and replacement, as recommended by the manufacturer's guidelines, are essential. The interval for changing spark plugs varies depending on the vehicle and the type of spark plug used.
  • Non-corrosive spring
  • This refers to the component of the oil seal that makes contact with the shaft.
    It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
  • In conclusion, PU oil seals are a testament to the power of material innovation in solving engineering challenges. Their superior properties, resistance to harsh environments, and adaptability make them a go-to choice for engineers seeking reliable sealing solutions. As technology continues to evolve, we can expect further advancements in the design and application of PU oil seals, contributing to increased efficiency and reliability in industrial operations.
  • The valve cover gasket is a small but essential component that seals the valve cover to the engine block. It is designed to prevent oil from leaking out of the engine and onto the ground. A worn or damaged valve cover gasket can allow oil to seep out, causing a mess under the hood and potentially damaging the engine.
