Cause Analysis of Deformation of Orifice Flow Meter

Abstract: The information on the cause analysis of the deformation of the orifice flowmeter is provided by the excellent flowmeter and flowmeter manufacturers. The orifice flowmeter belongs to the ancestors of the measuring instruments. It is favored by the majority of customers because of its low price and easy installation and use. Therefore, due to the limitations of its own principle and manufacturing process, deformation will occur after the working conditions become worse. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the analysis of the deformation of the orifice flowmeter. The orifice flowmeter belongs to the ancestors of the measuring instruments. It is favored by the majority of customers because of its low price and easy installation and use. Therefore, due to the limitation of its own principle and manufacturing process, deformation will occur after the working conditions become worse. The following flowmeter technology will analyze and explain this phenomenon for your reference: 1. The reason for the deformation of the orifice plate Analysis of the deformation of the orifice plate is because the gap between the outer diameter of the orifice plate and the annular chamber disappears after thermal expansion. When the orifice plate continues to expand, it cannot expand in the direction of the outer diameter, so under the action of the differential pressure on both sides of the orifice plate, the outlet side is generated. bulge deformation. Correlative clues are often found when investigating a site where orifice plate deformation has occurred. 1. It is related to the poor thermal insulation at the throttling device. The well-insulated throttling device did not leak. 2. It is related to the weather. The throttling device originally had no leakage phenomenon, but due to the cold weather and strong northwest wind blowing, it caused leakage at the junction of the positive and negative ring chambers. 3. It is related to the leakage at the junction of the positive and negative ring chambers. The leakage could not be eliminated by tightening the bolts, so the throttling device was removed to replace the gasket, and the orifice plate was found to be deformed. The above related clues can be combined to make a reasoning analysis of the deformation reason of the orifice plate. In the design and calculation of the throttling device, the gap between the outer diameter of the orifice plate and the ring chamber is large enough to assume that the temperature of the orifice plate and the ring chamber are the same, but in fact they cannot be the same. The orifice plate is surrounded by the ring chamber, and there is a high temperature. The fluid provides it with heat, so the temperature is high and it is fully expanded. The inner circle of the ring is in contact with the fluid, but the outer circle is in contact with the atmosphere, and the external ambient temperature and other factors make the temperature drop very low, resulting in insufficient reserved clearance and deformation of the orifice plate. The deformation of the orifice plate is related to the leakage at the positive and negative ring chambers. If the leakage is not caused by the damage of the sealing gasket, it is because the gap between the positive and negative ring chambers increases after the deformation of the orifice plate, and the gap between the sealing gasket and the ring chamber increases. gap. Second, the solution to the deformation of the orifice plate After finding the root cause of the deformation of the orifice plate, there is a simple and effective method to prevent the deformation of the orifice plate, that is, when designing and calculating, considering that the temperature of the ring chamber may be much lower than that of the orifice plate According to the actual situation, calculate the clearance reasonably. During the calculation, the temperature at the outer circle of the ring should not be higher than 100°C. Therefore, when the customer selects the model, it is necessary to fully communicate with the manufacturer and take all adverse factors into consideration. As a professional manufacturer of velocity meters, volumetric meters, differential pressure meters, and area meters, flowmeter manufacturers have been insisting on developing new technologies and products. Summarize the experience of production practice over the years, actively communicate with domestic and foreign flow fields, and strive to develop various flow measurement products to form a large-scale, systematic and diversified production pattern. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Analysis of the Causes of Deformation of Orifice Flow Meters'
