Vortex vacuum pump design and processing

Vortex vacuum pump design and processing, scroll vortex vacuum pump exists where the value? Vortex vacuum pump concept put forward, and how the design is produced? What are the design principles of vortex vacuum pump? World valve network for your troubleshooting, scroll vacuum pump design and processing. The concept of vortex true attractive for vacuum applications are: (1) simple structure, reliable work, a small number of parts (2) clean and pollution-free, vacuum pumping channel without oil (3) to save energy, a 30 (8.33 l / s) vortex vacuum pump requires only 0.6 ~ 0.75kW motor (4) to save running costs, vortex vacuum pump oil-free work, sealing or cooling are not required oil (5) fully balanced dynamic components , The concept of low vibration and low noise vortex was invented by Creux in 1905 and the world's first vortex model was manufactured in 1973 with a long history of 70 years. The basic reason why the vortex mechanism can not be machined and manufactured is the lack of sophisticated machining technology, the precise tolerance and meshing between the vortex lines, and the inability to control the leakage of the working medium and the performance index of the vortex vacuum pump. However, the scroll mechanism has the characteristics of no oil pollution in the exhaust passage, simple pump structure, low running cost, long working life, low energy consumption, stable operation and low noise, which is of great attraction and potential to the vacuum application industry The application value. In order to translate the concept of a scroll mechanism into a practical scroll vacuum pump product, over the past two decades, people have drawn lessons from the experience in the design and processing of scroll compressors to successfully design and produce a scroll driven scroll pump Vice and base plate, crankshaft, seals, anti-rotation mechanism and drive motor composed of five parts of the scroll vacuum pump. In order to ensure the performance of scroll vacuum pump performance, high efficiency and reliability, people have conducted a lot of theoretical research and experimental exploration. Work so far has focused on: Design Principles To translate the concept of a scroll mechanism into a practical scroll vacuum pump product, the following key technical issues have to be addressed: (1) improved sealing to reduce leakage; (2) less Small clearance, improve compression ratio; (3) optimize the structure and improve reliability; (4) simplify the production and processing technology, reduce the manufacturing precision requirements and reduce costs. In the vortex vacuum pump design from the pump efficiency and reliability of the starting, select the pump structural parameters. The first consideration is the performance of the pump, such as the ultimate vacuum, pumping speed, energy consumption, speed, size, weight and external dimensions, etc .; then according to the performance indicators to determine the pump internal structural parameters such as vortex type, Size, vortex wall thickness, vortex wall height and crankshaft radial eccentricity, etc. On the basis of performance index, the overall optimization of the pump is carried out, including the optimization of structural parameters, selection of pump body and sealing material, bearing selection, Surface treatment and drive motor matching and so on.

High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The Steel Tie Rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650, grade 785, grade 830, grade 930, grade 1080 etc.
