Issues regarding the circuit of reciprocating compressors
Thread Content
Generally, a circuit is present before the outlet of a reciprocating compressor, which is used to protect the equipment and control the outlet pressure. However, a return line is also added from behind the outlet valve of the reciprocating compressor to the compressor inlet. What is the purpose and advantage of this return line?
Its function is similar to that of the circuit valve mentioned earlier; the difference is that one controls the pressure of a single unit while the other controls the system flow rate. It’s a bit similar to the function of a system vent and recovery valve.
This should be an outlet circuit, whose main function is to regulate the outlet flow rate
For an accurate analysis, it’s best to provide detailed drawings; generally, the final check valve that comes with the compressor is sufficient to solve the problem.
Firstly, this valve is completely unnecessary for this machine – it’s an extra addition with no real purpose. Secondly, if such a circuit (valve) does exist, it can only serve one purpose, such as using external gas for replacement purposes. After all, the machine itself can also carry out gradual gas replacement upon startup; therefore, this approach must be related to your specific manufacturing process, and it’s impossible to determine anything without further detailed information. Otherwise, please refer to the previous one
:Lol, I guess their system operates more than two compressors at the same time; having a main return line on the main pipe makes things safer and more convenient for temporary adjustments
The main function of this line is to regulate the flow rate
Is it similar to the counter-rotation valve of a centrifuge, used to regulate the inlet flow? I haven’t dealt with restoring from a backup before. . :(:(
This check valve is used to regulate the pressure in the inlet air storage tank, ensuring that the pressure at the compressor’s inlet remains constant. This prevents negative pressure at the inlet due to unstable conditions, which could lead to air being drawn in
