Description

Technical Field

[0001] The utility model relates to the technical field of elliptical gear flowmeters, in particular to a combined elliptical gear flowmeter. Background Art

[0002] The oval gear flowmeter is a type of volumetric flowmeter, which is used for precise continuous or intermittent measurement of the flow rate or instantaneous flow rate of liquid in a pipeline. It is particularly suitable for the flow measurement of high viscosity media such as heavy oil, polyvinyl alcohol and resin. The oval gear flowmeter uses mechanical measuring elements to continuously divide the fluid into a single known volume portion, and measures the total volume of the fluid according to the number of times the metering chamber is successively and repeatedly filled and discharged with the fluid in the volume portion.

Multiple individual tests will increase the labor intensity of personnel and reduce work efficiency. The gear transmission system in the flowmeter is generally a pure mechanical component, and long-term operation is not conducive to its service life. The gap in the transmission component will also affect the fluid flow rate, thereby affecting the measurement accuracy.

However, the elliptical gear flow meter is fixed by the cooperation of an elastic gasket and a clamping part. The size of the clamping part is a fixed size, which is not convenient for fixing and then combining flow meters of different specifications, thereby reducing the use effect. Therefore, a combined elliptical gear flow meter is proposed to solve the above problem. Utility Model Content
