The HydroCOM system has failed
Thread Content
Problem description: I would appreciate it if someone who knows how this works could explain it to me regarding the operation of HydroCOM. The first issue is that the HydroCOM system is not connected to the system’s pressure control mechanisms; it operates independently. In such a case, if there is a malfunction in the HydroCOM system, will the load on the new hydrogen generator be 100%, and can this be adjusted by controlling Reactor 1/1 and Reactor 2/2? Since our device is equipped with primary and secondary pressure difference interlocks, can we adjust the situation by shutting down Reactor 1-1 and Reactor 2-2? Will this cause the system to shut down due to the interlocks? The interlock value is 5.04 for level 1 and 8.66 for level 2. How is it possible, how can adjustments be made? Question two: if HydroCOM and the system’s pressure settings are set to automatic, how does that work?
When the system fails, automatic operation will cease; it is necessary to switch to one reverse cycle followed by two reverse cycles right away, controlling the pressure between stages as well as the system pressure, and then switch from automatic to manual mode.
We use a hydraulic pressure interlock system; once the pressure drops below the set interlock value, stage 1 and stage 2 automatically adjust to 30%, after which manual adjustment is made to stabilize the level. Operating in automatic mode causes large fluctuations in the pressure ratio between stage 1 and stage 2, which is harmful to the compressor; we have always used manual mode to adjust the pressure ratio to an appropriate level, resulting in very stable operation. Given that you have pressure interlocks, the determination of the opening degree for the return line will need to take your empirical values into account.
