一、用途:
椭圆齿轮流量计是一种指针显示,字轮累积计数装置及回零装置的轻型容积式流量仪表,广泛应用于各工业领域的液体流量控制,适用于各种类型的液体测量,如原油、柴油、汽油等,具有量程大,精度高,使用和维修方便等特点,选用不同的制造材料,可满足石油、化工、医药、食品、冶金、电力、交通等各领域的液体流量计量。
二、工作原理与结构:
流量计是由计量箱和装在计量箱内的一对椭圆齿轮,与上下盖板构成一个密封的初月形空腔(由于齿轮的转动,所以不是密封的)作为一次排量的计算单位。当被测液体经管道进入流量计时,由于进出口处产生的压力差推动一对齿轮连续旋转,不断地把经初月形空腔计量后的液体输送到出口处,椭圆齿轮的转数与每次排量四倍的乘积即为被测液体流量的总量(原理见图1)。
流量计主要是由壳体、计数器、椭圆齿轮和联轴器(分磁性联轴器和轴向联轴器)等组成(结构见图)。

流量计的安装
1、安装前应*清洗管道,并在流量计前安装过滤器,以防止杂物进入流量计。被测液体含有气体时,应安装空气分离器。
2、应注意必须把流量计的椭圆齿轮轴安成水平位置,即表盘与地平面垂直。调节流量和启动,关闭的阀门应分别安装在流量计的进出口端。
3、流量计壳体上箭头指向应与被安装管道的液体流动方向*。
4、连续流程的管道,安装流量计的水平管道应装有旁路阀,以便定时清洗、检修。在垂直管道上流量计,应装在旁路管道中以防止杂物落入仪表内。
5、流量计在正确安装的条件下,为便于读数,可根据需要将计数器旋转180o或90o安装要求见
