Abstract:
标准孔板流量计计量装置是确定天然气产量和质量的关键设备，其上下游测量管内壁的光洁度对计量装置的精度和稳定性至关重要。通过建立标准孔板流量计流场分析模型，定量分析了不同管径、不同测量管粗糙度对孔板计量精度的影响，并优化设计了励磁振动除垢装置，通过实验研究确定了最优操作条件，证明了该测量管维护方法的有效性。该新型装置可以有效保障天然气计量系统的安全性、高效性、标准性，减轻员工的劳动强度，降低运行维护费用，具有较好的安全效应和广泛的应用前景。
The standard orifice flowmeter metering device is a key equipment for determining the output and quality of natural gas. The smoothness of the inner wall of the upstream and downstream measuring tubes is crucial to the accuracy and stability of the metering device. By establishing a flow field analysis model for a standard orifice flowmeter, the influence of different pipe diameters and different measuring tube roughness on the orifice metering accuracy is quantitatively analyzed, and the excitation vibration descaling device is optimized and designed. The optimal operating conditions are determined through experimental research, and the effectiveness of the measuring tube maintenance method is proved. This new device can effectively ensure the safety, efficiency, and standardization of the natural gas metering system, reduce the labor intensity of employees, and reduce the cost of operation and maintenance. It has a good safety effect and a broad application prospect.
