Cost comparison of Run Feng RX600 gas regulator and regulator station
Comparison of operation cost between console and regulator station
1. personnel cost comparison. At present, there are 54 regional pressure regulating stations in our city. Each regulator station has 1 managers. If it is calculated at 1000 yuan per person per month, it will be 54,000 yuan per month; the regulator cabinet does not need to be closely guarded by professionals; the inspector can watch four regulator cabinets by one person, which can save about 40,500 yuan per month.
2. comparison of operating costs of pressure regulating cabinet. The heating, water supply and drainage and electrical installations of the traditional pressure regulating stations are all available, and the maintenance costs are huge.
For example, the heating fee for each heating period is 33.6 yuan / m2, the area of the pressure regulating station is 55.65 m2, about 1 870 yuan; the pressure regulating cabinet heating is the electric mixing tropical zone, and the electricity consumption for each heating period is about 2 000 kWh, 1 400 yuan, and there is no other cost.
Three, problems and improvement methods
(1) the problems occurred during the past two years, a series of pressure regulating cabinets appeared.
Question:
(1) in winter, the flange interfaces in the box with different temperatures have been leaked in varying degrees.
(2) there is no power supply and explosion-proof lamp in the pressure regulating cabinet, and can not be maintained at night.
(3) export pressure is too high for 2.3KPa.
(4) filters are often blocked by dirt.
(two) improvement method
(1) Change the sealing of pressure regulating cabinet and pipe network interface from screw connection sealing ring to high pressure oil-resistant asbestos gasket sealing of flange interface;
(2) re access to power and explosion protection;
(3) replace the spring in the regulator.
(4) add a layer of polyester fiber on the outer surface of the filter core and replace it regularly. According to the above method improvement, our city added 22 pressure regulator cabinets, did not occur a gas shutdown, overpressure, low pressure phenomenon, running well.
Conclusion The improved pressure regulating cabinet not only meets the requirements of pressure regulating and gas supplying, but also meets the requirements of reducing engineering cost and beautiful garden environment. It is suitable for popularization and use in the North area. Now it has replaced the traditional regional pressure regulating station and become the preferred pressure regulating system in our city.
