Diamond friction-increasing gasket knowledge small popular science
Features: High hardness: diamond is one of the hard substances in nature, so diamond friction increasing gasket has extremely high hardness and wear resistance. High friction coefficient: The surface roughness and microstructure of diamond increase the friction between it and the contact surface, thereby improving the tightness of the connection. High temperature resistance: diamond has good high temperature resistance and can maintain stable friction coefficient and mechanical properties in high temperature environment. Chemical stability: Diamond has good chemical stability in most chemical media and is not susceptible to corrosion and oxidation.

Application of Diamond Friction Gasket in Petroleum Field
In the petrochemical industry, diamond friction pads mainly play a role in the following ways: First of all, in some high pressure, high temperature and the presence of complex fluid medium environment, diamond friction gasket with its excellent wear resistance and hardness, can effectively resist fluid erosion and wear in good condition, to ensure the performance of the equipment, to prevent damage Secondly, in the connection parts of some key valves, pumps and other equipment, it can provide a stable and reliable coefficient of friction to ensure the accuracy and reliability of equipment adjustment and operation. Furthermore, due to the petrochemical process may produce vibration and shock, diamond friction pads can withstand these dynamic loads, reduce the risk of loosening and damage to the connection parts, and maintain the normal operation of the equipment.
Diamond friction pads on automobile engines
With the continuous development of the automobile industry, the requirements for engine performance and reliability are increasing. As an advanced engineering material, diamond friction gasket is gradually showing its extensive and important application value in automobile engines.
Classification of automotive rubber products and their role in automobiles
The rapid development of China's automobile industry promotes the development of other related industries in China, especially the rubber industry. In the past few years, automotive rubber products have developed into a unique specialized product industry. Automotive rubber products are an indispensable and important component in auto parts. About 100-200 kinds of rubber products are installed on each car, and about 200-500 rubber accessories are used. In addition to tires, due to different specifications of cars, the consumption of rubber materials is about 15-60kg, and automotive rubber products (excluding tires) account for about 6% of the total cost of the car. There are more than 1000 varieties of non-tire rubber products for the automotive industry, with more than 8000 specifications. According to statistics, the automotive industry accounts for more than 70% of the world's annual consumption of raw rubber, of which tires account for 60% and automotive rubber parts account for 40%.

Working of Rubber Diaphragm Original Science
Diaphragm pump is a special form of positive displacement pump. It relies on a rubber diaphragm to drum back and forth to change the volume of the working chamber to inhale and discharge the liquid. The pneumatic diaphragm pump is mainly composed of two parts: the transmission part and the diaphragm cylinder head. The transmission part is a driving mechanism that drives the diaphragm to drum back and forth. Its transmission forms include mechanical transmission, hydraulic transmission and pneumatic transmission, among which hydraulic transmission is widely used. The working part of the diaphragm pump is mainly composed of a crank connecting rod mechanism, a plunger, a hydraulic cylinder, a diaphragm, a pump body, a suction valve and a discharge valve. Among them, the driving mechanism composed of a crankshaft connecting rod, a plunger and a hydraulic cylinder is reciprocating. The plunger pump is very similar.
