Leybold Vacuum Pump Leybold Vacuum Pump agent, Leybold Vacuum pump system price oerlikon leybold Oerlikon Leybold company in 1850, was founded in Cologne, Germany. Leybold has been at the forefront of the world of vacuum technology. Is one of the largest vacuum equipment suppliers in the world, with factories in four countries in the world: Germany, Cologne (headquarters): production of all series of products; Pennsylvania factory: specializing in the production of dry semiconductor industry pumps, cryogenic pumps; French tile Lang Sri Lanka factory: specializing in the production SOGEVAC series single-stage rotary vane pump; China's Tianjin factory: specializing in the production TRIVAC C series two-stage rotary vane pump and a single-stage rotary vane pump SV200B below. The key question is called the vacuum system vacuum system vacuum pump system pumps and other accessories designed by the combination of two sets or two more than the completion of a system to achieve the required degree of vacuum purpose is to select the main pump vacuum pumping unit of the main pump type is determined ( 1) determine the type of the main pump of the vacuum chamber of the need to establish a limit pressure. Usually the main pump limit selection pressure than the limit pressure chamber to an order of magnitude lower half. (2) The Commission main pump vacuum chamber according to the process required for the production of working pressure. Should correctly select the main pump operating point within the working pressure range, should be able to exclude all of the amount of gas produced in the vacuum chamber of the process. Therefore, the vacuum chamber working pressure must be within the optimum pumping speed pressure range of the main pump. (3) The volume of the chamber pumping time required to choose the size and the main pump. Vacuum chamber volume size of the system time affect the ultimate vacuum pumped. When the pumping time required by law, if the vacuum chamber volume increases, the main pumping speed is greater. (4) the right mix of vacuum pumps, vacuum pumps due to the selective extraction, thus sometimes choose one suction pump can not meet the requirements, requires several pump combination, complement each other to meet the pumping requirements. (5) If the stringent requirements of oil-free vacuum system, then you should choose a variety of free pump primary pump. If the requirements are not strict, you can choose a pump, then add some oil pollution prevention measures, such as adding cold trap, baffle, blocked oil wells, but also to achieve clean vacuum requirements. (6) When choosing pumps, you should know pumped gas composition, for selecting the appropriate pump was pumping gas composition. If the gas contains corrosive gas, dust particles, etc., you should consider choosing dry vacuum pumps, vacuum pumps and other corrosion-resistant. Or auxiliary equipment installed on the gas inlet duct of the pump. (7) Select the main pump based on the initial investment and ongoing maintenance costs of the entire vacuum system and other economic indicators.
