辽河石油勘探局于92年3月底召开了“环式离心流量计现场试用及技术考核鉴定会”,对建设部中国市政工程西北设计院研制的环式离心流量计进行了技术鉴定。 环式离心流量计采用离心原理,以结构简单的矩形过流断面的圆环导槽为主体,构成内部高光洁度的等截面流体过流通道,迫使流体改变流动方向,沿矩形过流断面的圆环导槽作圆周运动,产生离心力。该流量计是利用圆环导槽在同一横截面上内外侧的压力差测量流体流量。精度为0.5、1.0、1.5三种,公称直径D_N300以下。
Liaohe Petroleum Exploration Bureau held the “Ring Centrifugal Flowmeter Field Trial and Technical Appraisal Meeting” at the end of March 1992 to conduct technical appraisal on the ring centrifugal flowmeter developed by China Civil Engineering Northwestern Design Institute. Centrifugal centrifuge ring centrifugal principle, a simple structure of the rectangular cross-section of the circular guide channel as the main body to form a high-profile cross-section of the fluid flow passage cross-section, forcing fluid to change the flow direction along the rectangular cross-section of the circle Ring guide groove for circular motion, resulting in centrifugal force. The flowmeter is the use of annular guide groove in the same cross-section of the pressure difference between the inside and outside the fluid flow measurement. Accuracy of 0.5,1.0,1.5 three, nominal diameter D_N300 the following.
