Question 1

What is the calculation method of elliptical gear flowmeter?
Cx-m series flowmeter is the pressure of elliptical gear. Under the action of liquid pressure difference between the inlet and outlet ends of the instrument measuring chamber, a pair of elliptical gears continuously rotate on the bearing and discharge the liquid. The total value of liquid flowing through the instrument can be known by measuring the rotation number of the elliptical gear. Suppose that the volume Q discharged by the elliptic gear in one cycle of rotation is n, then the volume of liquid flowing through it is NQ

Question 2
What is the working principle of elliptical gear flowmeter?
As the first metering unit of the gear box (the metering unit of the next month) is the sealing of the gear box and the gear box, which is not the sealing unit of the next month. When the measured liquid enters the flow meter through the pipeline, a pair of gears are driven to rotate continuously due to the pressure difference generated at the inlet and outlet, and the liquid measured by the moon shaped cavity is continuously transported to the outlet. The product of the rotation number of the elliptical gear and four times of the displacement each time is the total flow volume of the measured liquid body. It is mainly composed of axial coupling, gear coupling and magnetic coupling.

Question 3
What are the characteristics of elliptical gear flowmeter? ?
Oval gear flowmeter It is the most commonly used flowmeter in industry and laboratory. It has the characteristics of simple structure, direct viewing, small pressure loss, convenient maintenance, high measurement accuracy and little influence by liquid viscosity. After proper installation Oval gear flowmeter It can ensure enough precision when using. It is a more accurate flow meter.

Question 4
What medium is suitable for elliptical gear flowmeter?
Oval gear flowmeter Especially suitable for measuring gasoline, diesel oil Lubricating oil Several hundred kinds of liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid, liquid. Buy Porcelain Xi flowmeter is to buy safety, convenience, ease of worry, rest assured.

Question 5
What are the advantages of elliptical gear flowmeter?
1. The measurement accuracy of elliptical gear flowmeter is high, the basic error is generally ± 0.5% R, and in special cases it can reach ± 0.2% R or higher. It is especially suitable for the field which needs high precision measurement.
2. There is no influence on the measurement accuracy when measuring the velocity field distortion of rotating flow and pipe choke, and there is no requirement for the front straight pipe section.
3. Porcelain Xi oval gear flowmeter can be used in the liquid level viscosity range of 0.3 ~ 100000 CPS, the range is generally 1:100, or 1:1000, and can achieve full range accuracy

Question 6
Why can't elliptical gear flowmeter be cleaned with gas?
Oval gear flowmeter A pair of elliptical rotors are meshed with each other to rotate and measure the fluid driven by the measured fluid. The maximum speed of the flow meter is relatively low, otherwise it will accelerate the wear and tear and even scrap the whole flowmeter. The gas has compressibility. When the gas pressure gradually increases and the elliptical rotor is started, the elliptical rotor will suddenly accelerate to rotate due to the large pressure difference between the front and rear of the flowmeter, far exceeding the maximum allowable speed, resulting in excessive wear and tooth beating of the rotor until the rotor can not be used.

Question 7
What measurement method does elliptical gear flowmeter belong to?
Elliptical gear flowmeter is a kind of volumetric flowmeter, also known as displacement flowmeter. It is a kind of flow meter with high measurement accuracy in Cixi instrument series. When the measured liquid enters the elliptical gear flow meter through the pipeline, a pair of gears are continuously rotated due to the pressure difference generated at the inlet and outlet, and the liquid measured by the initial moon cavity is continuously transported to the outlet. The product of the rotation number of the elliptical gear and four times of the displacement each time is the total amount of the measured liquid flow. Therefore, it is not difficult to find out from the measurement principle of the elliptical gear flowmeter that it is measured by the pressure head of the measured medium to drive the elliptical gear to rotate, and has nothing to do with the flow state of the fluid.

Question 8
What is the principle of an elliptical flowmeter?
The elliptical gear flowmeter uses mechanical measuring elements to continuously divide the fluid into a single known volume part, and measures the total flow volume according to the number of times that the metering chamber fills and discharges the fluid of the volume part successively and repeatedly. Porcelain Xi oval gear flowmeter can select different materials according to different industry media, which is suitable for flow measurement in chemical industry, petroleum, medicine, electric power, metallurgy, food, lubrication, odorization and so on. At present, the domestic elliptical gear flowmeter is only suitable for high viscosity liquid. Dto and OGM series are more common in the market. When the viscosity is low, it is easy to leak from the gap between gears, thus affecting the accuracy. The original national patent technology of Cixi elliptical gear flowmeter is applied in Siemens CNC cutting center, with cutting accuracy as high as 0.001mm, which ensures that our elliptical gear flowmeter can measure viscosity from 0.3 to 100000 CPS, and ensure the accuracy and no leakage. The role of the manufacturer's technical personnel, we preferred to put the product selection in the first place, only to do the correct selection, in order to avoid future problems, so we should pay attention to every detail problem, do a good job in every detail.
