Recently, Hebei Xuangong SD9, 430 horsepower drive bulldozers exported to Russia. The SD9 bulldozer is the "honor product" from the day of birth. Honor ★ SD9 high-drive crawler-type bulldozer is the largest horsepower bulldozer currently launched in China. ★ It was jointly awarded as “National Key New Product†by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce, and the General Administration of Quality Supervision, Inspection and Quarantine, and was awarded the Science and Technology Award of Hebei Province. ★ The product series of SD9 high-drive bulldozers was successfully selected in the "China Machinery Industry Famous New Mechanical and Electrical Products Catalogue". Is SD9 originally so concerned? ! What characteristics does it have compared to a typical bulldozer? Let's take a look at the structure of SD9: The overall features are outstanding. Modular design makes assembly, disassembly and maintenance more convenient. SD9 not only pays attention to the whole, but also tries its best to achieve "the perfect" in the details: 1. The front and rear guide wheels of the driving sprocket and the traveling system are arranged in a triangle shape, and the driving sprocket is placed high and away from the ground, thereby avoiding the direct impact load of the traditional bulldozer due to the contact of the driving sprocket with the ground, thereby improving the service life of the transmission system. 30%. 2, modular design, assembly, disassembly and maintenance is more convenient. 3. The pivotal connection structure improves the joint rigidity of the frame and the frame, so that the center of gravity of the whole machine can be easily adjusted to meet the requirements of different machines for the center of gravity of the whole machine. 4. The walking system adopts elastic suspension device, which can absorb the ground impact carrier and reduce the impact carrier that is transmitted to the chassis. 5. The hydraulic mechanical torque converter has the characteristics of strong adaptability of hydraulic transmission and high mechanical transmission efficiency. 6. The final drive system of the power shift transmission and the secondary planetary reduction mechanism has a more compact structure, higher transmission efficiency and less power loss. 7. The hydraulic system of the working device adopts the pressure compensation circuit, which reduces the hydraulic power consumption and improves the stability of the operation. The vertical design of the working device cylinder improves the shovel force of the blade. The oblique support structure brings the blade closer to the fuselage, which can control the load more accurately. The S-type blade has large capacity and the working efficiency is much higher than that of the ordinary bulldozer. 8. The vibration-proof installation of the anti-rollover protection frame is equipped with an electronic monitoring system to make driving more comfortable. All adjustable hanging chairs are deflected to the right by 15°, which is convenient for controlling the front and rear working devices, and has superior working vision, working performance and climbing ability. 9. The electronic monitoring system of the sound and light three-level alarm records and monitors the parameters such as water temperature, oil temperature, oil pressure, fuel quantity and working time of the diesel engine and hydraulic system. 10, a wealth of optional configuration, heavy ripper, centralized lubrication system, air conditioning system, cold start system, anti-fall protection, winch and so on. Hebei Xuangong is the only high-driven bulldozer development and manufacturer in China, and is a leading enterprise in the construction machinery industry in North China with integrated production, supply, sales and service. Deep research and development and manufacturing experience, achieving outstanding quality. With all the top ten advantages, such products are certainly more popular. (This article is from Xuangong)
PTFE Flange is a type of flange made from polytetrafluoroethylene (PTFE), which is a synthetic fluoropolymer of tetrafluoroethylene.
PTFE is known for its excellent chemical resistance, high temperature resistance, and low friction coefficient, making it an ideal material for use in various industrial applications.

PTFE Flanges are commonly used in piping systems to connect pipes, valves, and other equipment. They are designed to provide a leak-free seal and prevent the escape of fluids or gases. PTFE Flanges come in different types and sizes, such as slip-on flanges, socket weld flanges, blind flanges, and threaded flanges.
One of the main advantages of PTFE Flanges is their chemical resistance. They are resistant to a wide range of chemicals, including acids, bases, and solvents. This makes them ideal for use in chemical processing plants, where corrosive chemicals are present. PTFE Flanges also have excellent temperature resistance, and can withstand temperatures ranging from -200°C to +260°C.
