对小流量的测量,转子流量计很受欢迎。由于它是根据定压差的原理来考虑的,要根据各种重度不同的介质,选用各种不同材质的转子。在有些转子流量计中,干脆附带了一套由各种材质,如铜、铝、铅、不锈钢等做成的转子。在盐酸工业中转子材质问题尚难用金属来解决。为了使转子既能防腐,又具有相当的重度,这里提出的一种配重转子,是比较合用的。用具有一定机械强度,能在车床上加工的防腐材质做转子的外壳,其中灌入水银等重度较大的液态物质作配重,最后加以密封,这样就能成为一个既能防腐又具有一定
For small flow measurement, rotor flow meters are very popular. Because it is based on the principle of constant pressure to consider, according to a variety of heavy different media, use a variety of different materials of the rotor. In some rotameters, a set of rotors made of various materials, such as copper, aluminum, lead, stainless steel, etc., is simply attached. Rotor material in the hydrochloric acid industry is still difficult to use metal to solve the problem. In order for the rotor to be both anticorrosive and fairly heavy, the counterweight rotor proposed here is more compatible. With a certain mechanical strength, can be processed in the lathe anti-corrosion material to make the rotor housing, which was filled with mercury and other heavier heavy liquid material for the counterweight, and finally be sealed, so that it can become both a preservative and have a certain
