Compressor Maintenance and Troubleshooting

Content

Compressors can be divided into two categories based on their working principles: positive displacement compressors and dynamic compressors. Positive displacement compressors include piston, screw and vane types, which increase pressure by reducing the volume of gas. Dynamic compressors, such as centrifugal and axial flow, use the principle of kinetic energy conversion for compression. Each type of compressor has its specific advantages and usage scenarios. For example, piston compressors are often used in situations where intermittent compression is required, while centrifugal compressors are suitable for continuous large-flow compression operations. Choosing the right type of compressor is crucial to ensuring industrial production efficiency and energy conservation.

How Compressors Work

The destruction of pressure vessels at low temperatures is influenced not only by the quality of the steel but also by manufacturing and installation defects causing internal stress concentration.

LNG Compressor

The piston rod is made of 38CrMoAlA and the surface of the packing is nitrided to improve surface hardness and increase wear resistance. Threaded connection to the crosshead is used.Stuffing box structure: the packing is loaded from the working chamber of the cylinder, and a packing is placed in the first small chamber close to the working chamber of the cylinder for throttling.
