Centrifugal Compressors with Vertically Split Casing

Depending on required compression degree the centrifugal compressors with vertically split casing may have one or more compression stages, wherein each stage consists of an aerodynamic unit (“inner casing"), placed inside a steel cylinder. The aerodynamic unit, in its turn, consists of a rotor and a stationary flow path in form of horizontally split diaphragms.

The basic models can be modified in accordance with the customer requirements.

DESIGN FEATURES AND ADVANTAGES

• A vertically split casing allows fabrication of high-pressure compressors for explosive gases
• Flow path with high-performance compression stages
• Special locks securing solid forged caps that cover the ends of the steel cylinder, provide quick and easy maintenance and repair of the compressor
• Dry gas seals to provide complete purity of compressed gas and prevent its leakage into compressor room
• Active magnetic bearings for the rotor suspension
• Intercooling of compressed gas between sections in the two-stage casings
• Automation system based on microprocessor controller
• Many years of operation in real condition have proven high reliability and efficiency of the construction components

INSTALLATION

• Version for compressor stations (placement inside the permanent building)
• Hangar version with all engineering systems (easily construction buildings)
