Central control system
★The central control system adopts our self-developed Siemens control system, which can realize temperature, pressure, flow, leakage alarm and chain cut-off function.
★Touch screen display and operation adopts comprehensive Chinese interface, which is simple, intuitive and easy to operate.
★The central control system is mainly for remote display and chain control of the following parameters:     
★Gas inlet pressure;
★One-level regulator outlet pressure;
★The gas temperature before and after the primary heat exchanger;
★1st class heat exchanger return water temperature;
★Inlet high pressure cut-off;
★Secondary regulator outlet pressure;
★Gas temperature before and after the secondary heat exchanger;
★Secondary heat exchanger return water temperature;
★Gas outlet pressure and temperature of regulating station;
★Flow measurement;
★Gas leak alarm
★The amount of odor added by the odorizing machine.

★Firstly, it is connected to the skid-mounted tanker or cylinder set with high-pressure hoses and quick-fit fittings. 
★The 20MPa compressed natural gas enters the primary heat exchanger through the ball valve and high-pressure shut-off valve. 
★The gas is heated in the primary heat exchanger.           
The gas is then depressurized to 1.0~4.0MPa by the first stage regulator. 
★Enter the flowmeter for metering, and finally add odor to the gas and input to the medium pressure pipeline network.                
★Can then be reduced to 0.2-0.4MPa after the second regulator
★The gas pressure, temperature, heat, water temperature at all levels in the regulator station, control of key valves and switching between the two circuits are controlled by the central console.
Applicable medium:CNG compressed natural gas.
