摘要
目前用于煤矿瓦斯抽采计量的流量计普遍存在节流阻力损失、检测元件易受侵蚀、抗干扰能力较差等问题。通过研制矿用弯管流量计,利用流体的惯性在弯管处产生的差压计量管道流量,较好的解决了上述问题。
Currently,the loss of throttle resistance,susceptible erosion of test components and poor anti-interference ability and other issues is widespread existed in the flow meter used for coal mine gas drainage measuring.Through the development of mining elbow flow,using differential pressure of fluid inertia generated at the elbow pipe flow measured pipe flow.It solved these problems better.
