After a natural gas compressor increases the outlet pressure, does the compressor frequency rise or fall?
Thread Content
The maximum inlet pressure for natural gas is 0.15 MPa; the inlet pressure is set at 0.12 MPa, while the outlet pressure of the compressor is set at 1.70 MPa. The compressor frequency is 31 Hz. The intake pressure control valve is set at 0.13 MPa, and the compressor frequency is 32 Hz. If the outlet pressure of the compressor is increased to 1.8 MPa now, will the compressor frequency rise? After a natural gas compressor increases the outlet pressure, does the compressor frequency rise or fall?
When the outlet pressure is increased, the compressor frequency usually rises. Since more energy is required to overcome a greater pressure difference, the compressor must increase its operating speed in order to achieve a higher outlet pressure. .
It is recommended to strictly follow the process conditions specified for the equipment when carrying out operations; overloading should be avoided. There are also two ways to increase the outlet pressure of a compressor: one is by increasing the compressor’s speed, and the other is by reducing the opening degree of the outlet valve or by decreasing the amount of gas used. For reference.
Do you have an interlock value for the inlet pressure? If the inlet pressure is slightly positive, it’s okay; in that case, the frequency can be increased further to raise the outlet pressure
