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.

(1) If the horizontal slurry pump causes a blockage of solid hard deposits in the volute, measures can be taken to remove the blockage.
(2) If the shaft is different from the stuffing box axis, it is mainly due to processing errors and incorrect installation. Then pay attention to check whether the installation is correct after installation. If the sealing water ring is badly worn, a new water ring needs to be replaced. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, resulting in rapid wear of the packing, resulting in material leakage, you should dredge the blocked water pipe and keep the sealing water clean.
(3) If the impeller or the inlet and outlet water pipe is blocked, the impeller or pipe can be cleaned, and if the impeller is seriously worn, it should be replaced. If the filler mouth leaks, press the filler. If the conveying height is too high or the tube loss resistance is too large, the conveying height should be reduced or the resistance reduced.

  • For instance, in automotive engines, these seals prevent engine oil from escaping, ensuring efficient lubrication and reducing wear on critical parts
  • Oil or other seals can be used for grease and oil seals. A flexible lip, radial lip, or rotating shaft seal are different names for an oil seal. Single lip, double lip, triple lip, and four or more lips are frequent configurations. Double dust lip seal A seal with a garter spring design is the Double Dust Lip (DDL) seal. It has two dust lips, as the name would imply, plus a fluid lip with a garter spring to keep the lip firmly attached to the wear ring. Given the ongoing evolution of bearing seal designs, this seal would be considered a starting seal. For more than 50 years, this design has been the workhorse of the freight business; it still is in some regions. NBC Brenco Bearing Seal performs the fundamental task of keeping contaminants and grease out. Because of the garter spring, this seal would add the most torque and temperature to the bearing. Efficiency plus bearing seals Due to eliminating the fluid lip using poly inserts and rotors, the Efficiency Plus (EP) seal has a reduced torque value of fewer than 15 in-lbs. Although it features a triple dust lip rather than a double dust lip, the dust lip is still a molded component of the design. A labyrinth-like insert and rotor interlock each other to replace the fluid lip. NBC Brenco labyrinth provides excellent grease while lowering the torque required to rotate the seal. Other types of oil seal and grease seals include:
  • The integration of E6RTC and Spark offers several benefits for businesses
  • Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.

  • Maintenance and Replacement of Oil Seals

  • There are several key factors to consider when choosing the right spark plugs for your vehicle. The first is the type of spark plug, which can vary depending on the make and model of your car. There are three main types of spark plugs copper, iridium, and platinum. Copper spark plugs are the most common and affordable option, but they also have the shortest lifespan. Iridium and platinum spark plugs are more durable and offer better performance, making them a popular choice for many drivers.

  • Installing and replacing the 75x100x10 oil seal is a straightforward process that can be done by maintenance personnel with basic mechanical skills. It's important to ensure that the shaft and housing where the oil seal will be placed are clean and free of any debris or damage. Proper lubrication of the shaft is also crucial to prevent premature wear of the oil seal.


  • In the intricate mechanical symphony that is an automobile, each component plays a pivotal role in ensuring a smooth and safe driving experience. Among these components, the rear shock absorber, often overlooked, stands as a silent guardian against the harsh realities of our roads. Its oil seal, a diminutive yet indispensable part, ensures the integrity of the damping mechanism, preventing oil leaks that could compromise vehicle control and ride comfort.
  • One of the main advantages of Iridium Spark Plug is its ability to generate a more powerful and consistent spark, leading to improved engine performance and increased fuel efficiency

  • In the realm of engineering and mechanics, oil seals play a critical role in ensuring the efficient and safe operation of various machinery and systems. These seals, often overlooked, are the unsung heroes that prevent lubricants from leaking and contaminants from infiltrating. A unique trifecta - 35%, 2047%, and 7% - holds significant importance in understanding the intricacies of oil seal performance.
  • Another benefit of twin spark plug technology is enhanced engine durability. With two spark plugs firing simultaneously, the workload is evenly distributed, reducing the wear and tear on individual components. This results in a longer lifespan for the engine and its components, ultimately saving the driver time and money on maintenance and repairs.
  • The size and shape of the seal must also be considered. Seals come in a variety of sizes and shapes to fit different applications. It is important to select a seal that is the correct size and shape for the application in question.
