真空压力浸漆是真空压力浸渍技术应用之一.首先以浸漆罐的真空系统为例.比较了国内外的几种方案.认为利用国内产品组成的真空系统。其性能可达国外同类真空系统水平.对要求工作真空度为13.3帕.极限真空为6.65帕.抽空时间不得大于45分钟的真空系统.选择罗茨一滑阀泵和罗茨一水环泵机组.并对主泵.前级泵、抽气时间等分别进行了计算.最后从制冷剂与载冷剂选择.保温层厚度确定.冷负荷计算方面介绍了制冷系统的设计与计算.指出真空压力浸渍设备的真空系统和制冷系统的国产化是可行的。
Vacuum pressure impregnation is one of the applications of vacuum pressure impregnation technology.Firstly, the vacuum system of dipping paint tank is taken as an example.Several schemes at home and abroad are compared, and the vacuum system using domestic products is considered. Its performance up to the level of similar foreign vacuum system requirements for the working vacuum of 13.3 Pa. The ultimate vacuum of 6.65 Pa. Pumping time should not exceed 45 minutes of the vacuum system. Choose Roots a spool valve pump and Roots water pump unit .And the calculation of the main pump, the foreline pump, the extraction time and so on were respectively carried out.Finally, the thickness of the insulation layer was selected from the refrigerant and the refrigerant.The design and calculation of the refrigeration system were introduced in terms of the cooling load calculation.The vacuum pressure Impregnation equipment vacuum system and refrigeration system localization is feasible.
