    椭圆齿轮流量计 工作原理 :椭圆齿轮 流量计属 容积式流量计,主要部分是计量箱和装在计量箱内的一对椭圆齿轮,它们与盖板构成一密封的初月形空腔,作为量具。 I. Working principle of oval gear flow meter : The oval gear flow meter is a volumetric flow meter. The main part is a measuring box and a pair of oval gears installed in the measuring box. , As a measuring tool. 可以 推动椭圆齿轮旋转。 The pressure difference at the inlet and outlet of the flow meter can push the oval gear to rotate. The fluid is discharged after being measured by the lunar cavity, so the oval gear can output 4 times the volume of the lunar cavity every one revolution . Therefore, the number of revolutions of the oval gear is proportional to the flow rate of the fluid.

椭圆齿轮流量计 结构: 椭圆齿轮 流量计主要由本体、一对椭圆齿轮、磁性联轴器、调整齿轮、计数器 及发讯装置组成。 Structure of elliptic gear flowmeter : The elliptic gear flowmeter mainly consists of the body, a pair of elliptical gears, a magnetic coupling, an adjustment gear, a counter and a signaling device.

为两种: 单体和双体,单体 就是 体和 量箱为一体 双体 就是 壳体和计量箱为两体 The body of the flowmeter is divided into two types: single body and double body. The single body is the housing and the measuring box as a whole , and the double body is the housing and the measuring box as two bodies . 流量计 椭圆齿轮转数,通过磁性联轴器和一系列齿轮组成的减速机构,传到表头计数器。 The elliptical gear rotation number of the elliptical gear flowmeter is transmitted to the meter counter through the magnetic coupling and a series of gear reduction mechanism. Magnetic coupling is mainly composed of active magnetic steel and driven magnetic steel. The use of magnetic coupling can increase the working pressure and temperature of the flowmeter, ensure safe operation and reduce maintenance work.
