Centrifugal Compressor

With aerodynamic design, standard guide vanes, intercooler, backward inclined impellers, the compressor still maintains high efficiency when running in partial load, and minimizes the times of loading and unloading. The finned heat exchanger has a high cooling efficiency with low pressure loss. The water flows in pipes, while gas flows in the shell to reduce the maintenance cost.

The horizontal gear box facilitates the maintenance of bearings, gears, sealing element and the rotor. The cooling water flows in pipes to shorten the downtime to a minimum. When overhauling, there is no need to dismantle the pipeline. The screw tail cone pin enables convenient assembly and replacement. The intercooler is easy to clean, inspect and maintain.

The bearing runs stably in high speed. It should be aligned to ensure excellent anti-vibration and cooling effects. The using of gas seal, oil seal and other seals significantly reduces production and maintenance costs.

The automatic control system achieves safe and trouble free operation, surveillance and linkage control of multiple machines. With self-diagnostic function, the control system has a swift response to self-inspection. The large touch screen enables easy monitoring and simple maintenance.

Centrifugal compressor designed by Shanghai Xinran Compressor Co., Ltd. is driven by motor to meet the technological requirements of customers. It can provide 100% oil-free compressed air.

The air enters into the compressor through the regulating valve on the inlet. The impellers rotate in high speed to accelerate the air. Then the air enters into the diffuser, meanwhile the velocity is converted into pressure and heat. Finally, the air enters into the air cooler.
Such a process is repeated until the required pressure is reached.

The compressor unit includes: air system, lubricating system, drive system, control system equipment and other optional devices.
The air system mainly includes: the nose section and accessories.
