The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

  • Oil seals serve an important function in preventing lubricant leaks by closing in the spaces between the parts of the rotary shaft equipment. They also prevent dirt, dust, and other contaminants from clogging up the unit. Having them properly installed enables engines, pumps, and pipes to operate more efficiently.

  • They are generally utilised for the following purposes:

  • 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:

  • Moreover, the 7mm spark plug wires are designed to withstand high temperatures and mechanical stress, making them more durable and less prone to degradation over time
  • When it comes to shopping for spark plugs, understanding their construction and how they interact with your vehicle's specific requirements is essential. Spark plugs come in various materials such as copper, iridium, or platinum, each with its own set of benefits and drawbacks. Copper plugs are known for their excellent conductivity and are often more affordable. However, they wear out quicker compared to the premium metals. Iridium and platinum plugs, although pricier, offer longer lifespan and better performance under high stress conditions.
  • Lastly, 10% oil seals are designed for low-pressure applications. Their smaller contact area reduces friction, thereby minimizing heat generation and prolonging the life of the seal. These seals are ideal for applications where minimal wear and tear is expected, such as in light-duty machinery or in situations where a more dynamic sealing action is required.

  • Regular inspection and maintenance of spark plugs are essential to identify signs of wear, fouling, or deterioration. Proper replacement of worn or fouled spark plugs, including the transition to iridium spark plugs where applicable, is crucial for maintaining the efficiency and reliability of the vehicle's ignition system. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's engine.

  • OIL SEALS

  • How do oil seals work?

  • The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s. 

  • Steering Oil Seal and Its Impact on Vehicle Steering Mechanism

  • a) The shaft on which the oil seal is to be mounted should be ground with the surface finish or surface roughness between 0.2 to 0.8 Microns. It is best for the shaft to be hardened atleast to 40 – 45 HRc in order to prevent groove formation on the shaft due to the pressure exerted by the spring.

  • In addition to its durable construction, the AM5C spark plug is also designed to provide a strong and reliable spark. This is essential for ensuring that the air-fuel mixture is properly ignited, resulting in efficient combustion and optimal engine performance. The design of the AM5C spark plug ensures that it delivers a powerful spark every time, regardless of the operating conditions.

  • In the intricate world of mechanical engineering, oil seals play an indispensable role in ensuring the efficient and safe operation of machinery. The 40x52x7 oil seal is a specific type of sealing solution that is designed to prevent the leakage of lubricants while preventing the ingress of contaminants into critical mechanical components. This article delves into the details of this crucial part, its specifications, and its significance in various industrial applications.
  • In the intricate world of automotive engineering, every component plays a pivotal role in ensuring the smooth operation of a vehicle. Among these components is the unsung hero of the engine bay – the B18B1 valve cover gasket. This humble yet essential piece of automotive hardware safeguards against oil leaks and maintains the integrity of the engine's valve cover, making it a critical part of any well-maintained automobile.

  • When the total eccentricity is excessive, the sealing edge of the seal lip cannot accommodate shaft motions and leakage may occur.
    Total eccentricity is the sum of shaft runout and the housing-bore eccentricity.
    Total eccentricity, shaft runout and housing-bore eccentricity are generally expressed in TIR (Total Indicator Reading).

  • One of the key advantages of die-cut silicone gaskets is their ability to withstand extreme temperatures. They can maintain their integrity and properties in environments ranging from -100°C to 250°C (-148°F to 482°F), making them suitable for use in automotive, aerospace, and industrial machinery sectors. Their heat resistance also makes them ideal for use in cooking appliances and HVAC systems.
  • The choice of materials for metallic oil seals depends on the specific application requirements. Common materials used in the construction of these seals include stainless steel, carbon steel, aluminum, and brass. The sealing element, on the other hand, is typically made from materials such as nitrile rubber, fluoroelastomers, or PTFE, which offer excellent resistance to heat, chemicals, and wear.
