What are the consequences of excessive inlet flow to the compressor?
Thread Content
For a centrifugal compressor used to transport natural gas, if two compressors operate in parallel and one of them stops functioning due to a fault, the inlet flow rate of the remaining operating compressor increases sharply. What effects will this have on that operating compressor?
The current will increase significantly; monitor the changes in current. Answer completed
The inlet of the gas compressor requires positive pressure. If the inlet and outlet openings remain unchanged and one unit is suddenly shut down, the operating current of the other unit will increase. A system designed in accordance with standards takes into account the diameter of the inlet and outlet pipes to match the power of the motor of a single compressor when the valve is open to its maximum extent, thereby preventing the motor from tripping due to overcurrent. Usually, this step is checked during the single-unit load test of the equipment.
