人造粘胶强力丝生产中的纺丝原料——粘胶是一种高粘度的碱性流体,其粘度为55～90秒,换算成动力粘度时为7233～11835cp;使用处的实际流量为4～5m~3/h;介质呈碱性,且在安装方面工艺上不允许设副线等。这些均与流量计的使用技术要求有很大差距。经过对涡轮、电磁、靶式、齿轮等各种用于较高粘度介质的流量计的比较,我们认为椭圆齿轮流量计虽然与实际使用条件相比差距甚
Artificial viscose filament yarn production of raw materials - viscose is a high viscosity of the alkaline fluid, the viscosity of 55 to 90 seconds, converted to kinematic viscosity of 7233 ~ 11835cp; the actual use of traffic at 4 ~ 5m ~ 3 / h; medium is alkaline, and in the installation process is not allowed to set the secondary line. These are with the use of flowmeter technical requirements have a big gap. After the turbine, electromagnetic, target, gear and other flowmeters for higher viscosity media comparison, we believe that although the oval gear flowmeter compared with the actual conditions of use even worse
