Compressors

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 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.

Types and Applications of Compressors

How Compressors Work

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.

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.

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.

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

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.

Compressor Maintenance and Troubleshooting

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

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.
