本文重点介绍了作者在弯头流量计研究方面的成果以及在煤矿排水设备上经常使用的可能性.文章从理论上推导出弯头流量计计算流量的公式以及运用此公式计算流量系数的方法.这个公式与迄至目前国外发表的有关公式相比,更加有理有据,形式简单,阻力损失小,不怕混水污水,并且随时可以逆向使用等优点,适合于矿井排水使用.文章还对具体使用弯头流量计的技术问题,提出了具体意见.
This article focuses on the authors’ achievements in the research of elbow flowmeters and the possibility of frequently used in the draining equipment of coal mines.This paper theoretically deduces the formula of elbow flowmeter calculating flow and the method of calculating flow coefficient using this formula. Compared with the formula published in foreign countries till now, this formula is more rational and evidence-based, simple in form, less resistance loss, not afraid of mixed water and sewage, and can be reversely used at any time, which is suitable for mine drainage. Elbow flowmeter technical problems, made specific comments.
