Analysis of advantages and disadvantages of RX900 regional voltage regulation
1. Regional pressure regulation technology is that after the city medium pressure gas pipeline enters the regional pressure regulation station (room), after the pressure is adjusted to the user's need pressure, it is transported to the user through the low pressure pipeline network.
1.1 Advantages of Regional Voltage Regulation:
It has large gas supply capacity and is convenient for centralized management and maintenance.
The distance of medium pressure gas pipeline is short and the operation risk is reduced.
1.2 Disadvantages of Regional Pressure Regulation:
Pressure regulating station location requirements are high, not only to meet the safety distance requirements with other buildings and structures, but also to be located in the center of gas load or close to large users. In today's urban land inch by inch, location selection is more difficult.
Medium and low pressure gas pipelines may be parallel for a long distance, and the diameter of low pressure pipeline network is large.
Not only takes up more underground resources, but also the pipeline is very difficult.
The construction cost of surge station (room) is higher.
The gas supply range is large, so the pressure of each gas point is unstable, and it is prone to overpressure or underpressure.
The pipeline network and pressure regulating facilities have a large impact on customers when they are repaired.
