PEM large electrolysis equipment
Key words:
Classification:
● Minimum gas volume in the system
● Minimal pressure can be detected to prevent air from entering
● Fail-safe standard communication protocol
● Continuous hydrogen leakage detection
● Fail-safe logic control
● Uninterruptible power supply to ensure safe shutdown in case of power failure
● Continuously monitor the purity of the oxygen product
● Multi-layer control system
● Multiple redundant protection of key safety parameters
● Pressure control: The operator can select the appropriate gas pressure (8-10 bar) through the HMI (human machine interface) on the control panel, which can automatically adjust the production rate to maintain the set pressure.
● automatic cooling: cooling water through the control of the flow control valve to control its flow into the heat exchanger. When the temperature rises, the flow rate is automatically increased to ensure a stable hydrogen production temperature.
● Set energy consumption: In order to integrate the fluctuation of power resources, the maximum output of hydrogen can be produced under limited conditions according to the set power, while ensuring the normal operation of other utilities.
● Fully automatic nitrogen purge: the control system will program the operation of different valves to complete the nitrogen purge. Make sure that all air is removed from the system before hydrogen production.
● Remote I/O: Using the most advanced profibus connection system, based on this technology, we have greatly reduced the connection of field cables. The control system is more safe and reliable and meets the most stringent safety standards and specifications. The control system will automatically analyze and diagnose any communication failure, which not only improves the safety of the system, but also reduces the time of fault analysis, search and maintenance.
