Reciprocating hydrogen compressor
Thread Content
What is the function of the reciprocating hydrogen compressor loader? Can any expert please help answer this question?
Mainly to protect itself under overload conditions and adjust pressure\temperature\flow
The load controller should control the operating load of the compressor. I have seen three gears: 0%, 50%, and 100%.
I agree with the statement on the third floor. In order to reduce the motor starting current when the compressor is started, the loader is gradually loaded from 0% to 100%.
In fact, it is an unloader, called UNLOADER in English. Its purpose is to adjust the load according to external needs when driving a prime mover with a constant speed.
So, does the loader use wind to start?
The unloader can open the cylinder intake valve to adjust the flow, and at the same time, it can realize no-load driving (all intake valve unloaders work, 0 load, but the time cannot be too long, load immediately after starting)
The unloader is actually a set of air valve top-opening devices, with only fully open and fully closed positions. It can run smoothly when switching the compressor without causing large pressure and flow fluctuations. Since the friction of the air flow at the air valve will generate heat and form heat accumulation in the cylinder, which will increase the temperature of the cylinder, so the unloader is only used to start and stop the compressor, and is not suitable for long-term operation.
