What is the impact of an oil-free lubricated piston compressor with the primary inlet valve closed on the equipment?
Thread Content
One of our trainees, who wasn’t properly supervised by the instructor, operated a two-stage piston compressor by connecting it to the system with the inlet valve closed. I wonder what effects such operation might have on the equipment
The import function isn’t activated; is the equipment creating negative pressure? Open the outlet valve – is the outlet pressure higher than that of the pipeline network? Is there a check valve on the outlet?
Since no intake air is supplied, it’s as if the system is operating under no load; therefore, the pressure at the second-stage outlet will not be higher than the system pressure. How can it then be connected to the grid?
Reply to 2# zxzxx321: There is a check valve at the outlet, and the check valve is leaking
It’s okay, I’ve driven before: lol
Reply to 6# Bi Jian: There will be no problem. Since the inlet valve isn’t open, it’s as if the system is operating under no load; there’s no gas in the cylinder to be compressed, and therefore the outlet valve also won’t do any work. It doesn’t matter even if it’s connected to the grid; the outlet pipes are equipped with check valves, so the gas in the pipeline won’t flow into the compressor. Operating under these conditions will not have any adverse effects on the cylinders or the transmission components.
