<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">YT-LC椭圆齿轮流量计(又称排量流量计、齿轮流量计),属于容积式流量计一种,在流量仪表中是精度较高的一类。它利用机械测量元件把流体连续不断地分割成单个已知的体积部分,根据计量室逐次、重复地充满和排放该体积部分流体的次数来测量流量体积总量。椭圆齿轮流量计可以选用不同的材料(铸铁、铸钢、304不锈钢、316不锈钢)制造,适用于化工、石油、医药、电力、、船舶、燃油、冶金和食品等工业部门的流量计量工作。特别适合于重油、聚乙烯醇、树脂、润滑油机油、柴油等粘度较高介质的流量测量。*n>*n>*n>*n>

<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">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。*n>*n>*n>*n>
<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">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。*n>*n>*n>*n>
