New hydrogen reciprocating compressor
Thread Content
For the new hydrogen reciprocating compressor 2D20-3.3/20-185, manufactured by Yuanda Compressors, what are the reasons for the high temperatures at the angle valves located after the fillers and cylinder oil injectors? Is it due to excessive wear of the filler and piston rings? An oil injection volume of 6~15 drops per minute by the oil injector is normal.
It has flowed back. Isn’t there a small valve for releasing air at the end? Release the air by pressing it a few more times, and then use the oil injector to push the oil in
If the check valve leaks, hydrogen will flow back.
On the devices I’ve seen, there is no valve behind the check valve; it’s directly connected to the oil filling point. Both locations are at high levels, so mechanical damage to the valve is likely to be ruled out. Where does the high temperature come from? It comes from the hydrogen at high temperature. With such a high pressure ratio, how is it a 2D model there? It should be a 3M or 4M model, right? . .
It consumes less air; it is designed on a grand scale, with the second and third cylinders being single-row double-acting types, and the second cylinder being located on the cover side.
With such a high compression ratio in the future, it is best to use three-stage compression. In the process design, using single-acting compressors or 23 stages in series is merely a last resort due to the lack of better options, and it introduces many factors of instability. The temperature is high; the only thing that comes to mind is a leak. It’s best to have the manufacturer analyze it – they will surely cooperate to resolve the issue.

If the amount of oil applied is normal, then there should be no problem with the check valve. You can measure the temperature of each angle valve, as well as the temperature of each exhaust outlet. Consult the manufacturer regarding the operating temperature range for these angle valves to see if they are within the normal limits
