采用气体循环法是使气体样品充分混合获得均匀试样的一种方法.为此目的设计试制了电磁循环泵,泵的主要特点是可在高温及压力下使用,不用滑润剂,避免污染,结构简单易于制作,可以调节活塞冲程数.
The gas circulation method is a method for thoroughly mixing gas samples to obtain a uniform sample. For this purpose, an electromagnetic circulating pump was designed and manufactured. The main features of the pump are that it can be used under high temperature and pressure without the use of lubricants to prevent contamination. Simple and easy to make, you can adjust the number of piston strokes.
