A simple vane pump includes a circular rotor that rotates in a larger circular cavity. The centers of the two circles are offset, causing eccentricity. The blades are allowed to slide in and out of the rotor and are sealed at all edges to form a blade chamber to complete the pumping work. On the intake side of the pump, the volume of the vane cavity is increasing. These increasing volume vane cavities are filled with fluid driven by inlet pressure. The inlet pressure is actually the pressure from the pumping system, usually just atmospheric pressure. On the discharge side of the pump, the volume of the vane cavity decreases, forcing fluid out of the pump. The function of the blade is to expel the same volume of fluid with each rotation.


Generally, the pump mechanism includes a cylindrical...  Moins

First, methyl silicone was synthesized, and then polysiloxane was synthesized. Because their structure is composed of si repeating units with organic group components directly bonded to silicon atoms, silicones are in a transitional position between inorganic and organic polymers. It is considered to be an organic derivative of silica sand or silica.


　　
The industrial production speed of silicone is extremely fast, and the world’s current output is 300,000 islands, which reached 600,000 islands in 2003, and the value is about 5 billion US dollars. Silicone is now widely used in defoamers for detergents and dyeing aids in elastomer materials, cosmetics, papermaking, textiles, resin preparations, and electronics industries. The first application of silicone in textiles is dimethyldichlorosilane for waterproof finishing. Later, more advanced polymethylhydrogen siloxane was developed, which made the application of silicone additives in waterproof...  Moins
