Seals are materials or parts that prevent fluid or solid particles from leaking from between adjacent bonding surfaces and prevent foreign impurities such as dust and moisture from entering the components inside the machine. The storage temperature of the seal is preferably below 30 ° C to avoid high temperature aging of the seal. Seal development Although the rubber seal is small, its role makes it a basic component and accessory in the main national economic industries such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and it plays a very important role in the development of the national economy. In recent years, with the rapid economic growth, the rubber and plastic seal manufacturing industry has maintained double-digit growth. The data shows that in 2011, the size of China's rubber and plastic seal manufacturing industry (above companies (according to the statistical caliber of the National Bureau of Statistics, sales revenue of more than 20 million yuan) achieved a total industrial output value of nearly 10 billion, an increase of more than 20%. China Rubber and Plastic Seals There are more than 150 companies in the manufacturing industry (with an annual income of 20 million yuan), and the domestic rubber seal industry generally shows a small-scale and low-tech development situation. From the perspective of the economic type of enterprises, private and foreign-funded enterprises account for The ratio is over 95%, which is the main economic type of the industry. At the same time, enterprises are basically concentrated in East China. From the number of enterprises, sales revenue and asset scale, East China has occupied a considerable share and the market concentration is high. A private enterprise in China's seal industry serves a variety of customers with high-quality products and efficient service concepts.

Common hydraulic seal classification Different types of seals are available depending on the application requirements, such as V ring, U ring, O ring, Y ring, etc.The original type of sealing ring is different, the medium resistance, hardness, and range of use are different! YD seals will guide you to learn more knowledge about hydraulic seal.

Basic introduction of dust seal The dust seal is a rubber seal ring for vehicles, machinery, construction machinery, and special purpose to prevent the intrusion of dust and dirt. The dust seal is generally used with a rubber rubber ring. It is used in some mechanical equipment and hydraulic piston systems, and is installed at the mechanical connection to prevent external dust and dirt from entering the equipment, especially in harsh environments. Large excavator dozers require a large amount of dust-proof packaging on the four-wheel, hydraulic system to prevent sand intrusion and protect machinery.

Piston Seal SPGO Application Range This is a standard combination seal for a wide range of applications. Has the same performance as SPG. Standard Material Seal: Filled with polytetrafluoroethylene F-PTFE O Ring: NBR or FKM Feature The sliding material is filled with polytetrafluoroethylene, which has a low frictional resistance, eliminates creep and ensures high wear resistance. Since the single seal has a two-way sealing capability, the installation space is eliminated.
