2. What is the working principle of the waist wheel flowmeter
Abstract: The waist wheel flowmeter is a type of volumetric flowmeter, named after one or two pairs of waist wheels that can rotate tangent to each other inside the housing. The waist wheel flowmeter measures the flow rate by interlocking the two waist wheels, calculating the volume of the measuring chamber and the number of waist wheel rotations.
. The waist wheel flowmeter has a novel design, beautiful appearance, high accuracy, easy installation and use, and long service life. However, it also has disadvantages such as large volume, heaviness, high pressure loss, and significant vibration during operation. Lets learn about the installation requirements of the waist wheel flowmeter together.
What is the working principle of the waist wheel flowmeter? The waist wheel flowmeter, also known as the Roots flowmeter, belongs to the volumetric flowmeter and is a high-precision measuring instrument used for continuous or intermittent measurement of flow in pipelines. It is commonly used for flow measurement of large-diameter gas, liquid, and steam medium fluids in industrial pipelines.
. The working principle of the waist wheel flowmeter is that there is a measuring chamber inside the housing of the waist wheel flowmeter, and there are one or two pairs of waist wheels that can rotate tangentially in the measuring chamber. A pair of transmission gears are coaxially installed with two search wheels outside the casing of the flowmeter, and they mesh with each other to enable the two waist wheels to interlock. When fluid passes through the flowmeter, the two waist wheels will r
2. Advantages and disadvantages of waist wheel flowmeter. The waist wheel flowmeter can be used for flow measurement of various clean liquids, especially for oil metering, and can also be made into a flowmeter for measuring gases. It has both advantages and disadvantages.
1、 The advantages of waist wheel flowmeter include innovative design, beautiful appearance, high precision, easy installation and use, long service life, etc. The waist wheel flowmeter has high accuracy, reaching 0.1-0.5 level. However, factors such as viscosity, temperature, pressure, flow rate, impurities, etc. can have a certain impact on the measurement accuracy.
2、 The disadvantages of a waist wheel flowmeter are its large size, heaviness, high pressure loss, and significant vibration during operation. However, in terms of noise, the use of two pairs of waist wheels at a 45 degree angle can greatly reduce the vibration noise during operation.
3. Installation requirements for waist wheel flowmeter: The waist wheel flowmeter is a high-precision measuring instrument, so there are also high requirements for installation. The requirements for installing the waist wheel flowmeter are:
1. The flow direction is consistent, and the horizontal pipeline is installed perpendicular to the generator. The vertical pipeline requires a bottom in and top out direction.
.2、 The diameter of the pipeline s
