Hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor, and the oil is inhaled from the hydraulic tank to form a pressure oil discharge and sent to the executive component. Hydraulic pump according to the structure is divided into gear pump, piston pump, vane pump and screw pump.

The project was approved in 2007. After three years of hard exploration, Chongqing International Composites Co., Ltd. broke through the foreign technology blockade, mastered the design and manufacturing technology of large-scale spinning tank kiln structures, and built the world’s largest and world-class level. The 36,000-ton/year electronic grade glass fiber demonstration production line breaks the monopoly position of Japan and the United States in ultra-fine electronic grade glass fiber products and realizes the localization of E225, DE300, D450 and D900 series ultrafine electronic grade glass fiber products. Large-scale production. During the research process, the research group developed 5 key technologies, 4 high-end new products, and formed 7 invention patents and 4 technical standards.
At present, the ultra-fine electronic grade glass fiber and products developed and produced by this project have been applied in the fields of electronics, aerospace, aerospace and defense. In addition, the ultra-fine electronic yarn developed by this project has also effectively promoted the development and upgrading of electronic grade glass fiber-electronic cloth-copper laminate and PCB industry chain.
The role of hydraulic pump:
Hydraulic pump is a hydraulic component for hydraulic transmission to provide pressure liquid, is a kind of pump. Its function is to convert the mechanical energy of power machines (such as motors and internal combustion engines, etc.) into liquid pressure energy. Figure shows the working principle of single plunger pump. The CAM is driven by a motor to rotate. When the CAM plunger upward movement, the piston and cylinder formed by the sealing volume is reduced, oil extruded from the sealing volume, through the one-way valve to the place where you need to go. When the CAM is rotated to the curve of the falling part, the spring forces the plunger down, the formation of a certain vacuum, the oil in the oil tank under the action of atmospheric pressure into the sealing volume. The convex wheel keeps the plunger rising and falling, the sealing volume periodically decreases and increases, and the pump keeps absorbing and discharging oil.
The development and industrialization of the key technology of ultra-fine electronic grade glass fiber under the project of the National Science and Technology Support Plan undertaken by Yuntianhua Group's subsidiary Chongqing International Composite Materials Co., Ltd. has successfully passed the site acceptance of the Ministry of Science and Technology.
