What are the material of the oil seal
Oil seal commonly used materials are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, PTFE and so on. 1. nitrile rubber (NBR) It has good heat resistance, wear resistance, resistance to various lubricants, greases, oil and gas mixtures, and the use temperature is -30~120 degrees Celsius, but it cannot be phosphate ester hydraulic oil and gear oil containing extreme pressure additives. Stable performance in gasoline and low aniline point mineral oil.

What is the purpose of the combination gasket seal ring
The combined gasket sealing ring is formed by integrally bonding and vulcanizing a rubber ring and a metal ring. It is a sealing ring used to seal threaded and flange connections. The ring includes a metal ring and a rubber gasket. When configuring, we must pay attention to the corresponding metal ring and rubber gasket, so we must understand the use of the combined gasket.

What factors should be considered when choosing an O-ring
O-ring because of its low manufacturing cost and easy to use, which is widely used in a variety of dynamic and static sealing occasions. O type sealing ring sealing mechanism: O-ring is an automatic two-way sealing element. The pre-compression of its radial and axial aspects during installation gives the O-ring its own initial sealing capability. It increases with the increase of system pressure.

Installation and Use of Silicone Seal
The installation method of mechanical seals, the form of mechanical seals, and the types of machinery and equipment are different and different, but the essentials of installation and use are almost the same. Mechanical seals are one of the basic mechanical components with high precision and relatively complex structure types. Installation methods and common precautions are as follows:

How to accurately calculate the number of friction values of seals (oil seals)
How can we accurately calculate the friction coefficient of surface sealing products such as seal oil seal seal ring? We believe that the force between a moving seal and the sealing surface is related to many factors, such as the structure factor of the seal, the sealing material factor, fluid and fluid pressure, humidity, friction speed and cleanliness.

Introduction and application of O-ring
O-ring is a rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called O-shaped rubber sealing ring, also called O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element for steam engine cylinders. O-rings are a common mechanical design for seals because they are inexpensive, simple to manufacture, reliable in function, and have simple installation requirements.

Standard and Material Selection of Gasket
The main function of the washer is to reduce the compressive stress of the bearing surface and protect the surface of the connected piece. In order to prevent the loosening of the connecting pair, anti-loosening spring washer, multi-tooth lock washer, round nut stop washer and saddle, wave and cone-shaped elastic washers can be used. The flat washer is mainly used to reduce the pressure. When the axial force of tightening some parts is large, the washer can be easily pressed into a disc shape. At this can be solved by using materials and increasing hardness.
