干式螺杆真空泵是技术含量非常高的科技产品,其制造的难度集中在两螺杆的型线设计和加工过程中。螺杆真空泵的内核部分——螺杆转子,是三维立体结构,要求在螺杆研发设计中采用三维曲面数学模型进行设计和求解,通过三维数学模型形成的实体加工需要在五坐标联动的数控设备上加工,设备造价昂贵、同时该设备的进口也受发达国家技术封锁的限制。为了能够在国产的三维数控设备上加工,需要将三维立体曲面模型方程通过傅立叶变换,求解转化为某断面的二维数学模型,方可应用于实际生产加工过程。整个螺杆真空泵的设计和加工过程,是一个极其复杂的理论求解和数控过程,技术含量相当高,同时螺杆泵的整机控制也是涉及了光、机、电等多领域的技术。由于螺杆真空泵的技术特点,采用双螺杆转子形成真空,因此,具有其他真空获得设备所*的技术优势。 性能特点Specificatin: 1、工作腔内无任何介质,可获得清洁真空。There is nothing in the pump cavity, so we can get a clean vacuum environment. 2、工作腔及螺杆转子表面有防腐涂层,可适应恶劣工况。There are antisepsis coat in the surface of pump cavity, so our pump can work in the abominable environment. 3、气体在泵内无压缩,适宜抽取可凝性气体。Air can not be compressed in the pump, so our pump can get coagulable air. 4、单台泵可从大气抽至1Pa,真空系统可大大简化。Air can be deflated to 1 pa by a single pump 5、水温对真空影响小,节水达90%以上,甚至可以不耗水。Less influence by the water temperature, economize 90 percent water so much as waste no water. 6、不耗油,无滴漏。No oil waste, no leek 7、旋转部件间无摩擦,可高速运转,整机体积小。No attrition between revolving part, high-speed and little cubage 8、结构简单,维护方便。Simple structure and convenient maintain 9、被抽气体直接排出泵体,不污染水,无环保压力,气体回收更便捷。Air can be took out directly and no pollution. 10、可与罗茨泵、分子泵组成无油机组。The DP Series Screw Dry Vacuum Pump can be able to work with ROZI pump and Molecule pump to make up of a whole dry vacuum set. |
