(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

  • 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

  • A7TC spark plugs work by creating a high-energy spark that is capable of igniting the fuel-air mixture more efficiently. The unique electrode design of A7TC spark plugs ensures that the spark is sustained for a longer duration, which in turn leads to more complete combustion and improved engine performance.

  • The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.

  • Homeowners and DIY enthusiasts also appreciate the convenience of a 1-inch rubber gasket. It's a straightforward solution for fixing leaky pipes under sinks or securing loose-fitting appliances. The ease of installation, combined with the low cost and wide availability of these gaskets, makes them an accessible option for quick fixes and long-term maintenance.

  • Car engine oil seal is a crucial component in any vehicle's engine system. It plays a vital role in preventing oil leaks and maintaining proper lubrication of the engine components. In this article, we will discuss the importance of car engine oil seals, their functions, and the consequences of a failing oil seal.

  • Installation techniques must be carefully selected and executed to ensure the seal functions correctly throughout its service life. Each technique addresses specific installation needs and ensures long-term reliablity.

  • Metallic oil seals consist of a metal casing or carrier that houses a flexible sealing element made of a resilient material such as rubber orPTFE (polytetrafluoroethylene). The sealing element is designed to conform to the surface of the shaft or housing it is，。 The metal casing provides strength and durability, while the flexible sealing element ensures a tight seal even under extreme conditions.

  • Different Types of Oil Seals

  • Rubber sheet white gaskets are essential components in a wide range of industrial applications. These gaskets are used to create a seal between two surfaces, preventing leakage of liquids or gases. They are commonly made from flexible rubber materials that can conform to irregular surfaces and provide a reliable barrier against environmental elements.
  • Rubber edge gaskets are widely used in industries such as automotive, aerospace, construction, and manufacturing, where sealing performance is critical to the safety and efficiency of operations. In the automotive industry, these gaskets are used in engine components, fuel systems, and HVAC systems to prevent leaks and ensure proper functioning of the vehicles.

  • The 38x52x7 oil seal is a popular size that is used in a variety of applications. It is commonly used in automotive engines, industrial gearboxes, and hydraulic systems. The seal is designed to withstand the high speeds and temperatures that are common in these types of machinery, and it provides reliable protection against oil leakage.

  • A more comprehensive study of aeration by Dinzburg8 showed that even a minimal level of aeration of an aggressive European SF oil led to protection of a VDF/HFP/TFE compound, but to severe deterioration of an HNBR compound. He notes that aeration increases the severity of aging in oil for silicone and acrylic elastomers, while decreasing the severity for FKM elastomers.

  • Oil seals are typically made from materials such as rubber, silicone, or PTFE (polytetrafluoroethylene). These materials are chosen for their ability to withstand harsh environments, resist wear and tear, and maintain flexibility over time. The choice of material depends on factors such as the type of fluid being sealed, the operating conditions, and the required durability of the seal.
