Compressor stuffing box construction

Widely used in LNG liquefied gas station, BOG gas small displacement filling bottle, the machine has less energy consumption, low noise, low vibration, high reliability, easy to operate and so on.

Welding quality significantly impacts the manufacturing quality of low-temperature pressure vessels.

Compressor Maintenance and Troubleshooting

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.

The compressor set is ZW type, oil-free, one-stage compression, and the whole set is arranged on a common base. The set has a compact structure, smooth operation, easy maintenance, low noise, low vibration, safe and reliable.

Gas compressors are reciprocating devices that raise gas pressure and pressurize the gas; this allows LPG (liquefied petroleum gas) to be transported via pressure differential and vapour transfer.

Widely used in LPG liquefied gas station, BOG gas small displacement filling bottle, the machine has less energy consumption, low noise, low vibration, high reliability, easy to operate and so on.

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.

The structure of compressors produced by our company are simple and reliable. The cylinder seat is made of grey cast iron and is positioned with the middle body using a pin or stop. The valve is arranged axially on the cylinder seat.

Beyond static storage, low-temperature tanks play a vital role in the dynamic field of LNG transportation.

Types and Applications of Compressors

How Compressors Work

The crankshaft is made of high quality carbon steel, with a single abduction and balance weight. The crankshaft is made of high quality carbon steel, with a single turn and a balancing weight.

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.
