- 摘要:
- 天然气从接收站输送到输配管网，再从输配管网输送到城市燃气管网均需要调压，天然气调压器是连接天然气输配管网、城市燃气管网的核心设备，分析调压器的性能有其独特性。以天然气输送过程中广泛应用的自立式调压器为对象，从力学角度分析自立式调压的一般原理，以及管道出口压力、噪音、节流效应等因素对调压器的影响，结果表明控制调压器上下游压差，天然气中的杂质含量，根据当地气温情况是否加设加热设备等措施，对于提高调压器运行可靠度，保障天然气站场具有现实作用。
Pressure regulation is necessary for nature gas transported from gas delivery station to gas transmission and distribution network and to city gas network. Gas pressure regulator is the key equipment in gas transmission and distribution network and city gas network. Taking self-operated gas pressure regulator widely applied in natural gas transportation and transmission system for an example， described are general principles of the pressure regulator by means of mechanics and analyzed are effects of such factors on the pressure regulator as pipeline outlet pressure， noise and throttling effect. The findings suggest that such measures as control on differential pressures of upstream and downstream pressure regulators and gas impurity content and heating equipment addition have realistic effects on operation reliability of pressure regulator and proper operation of gas compressor station.
