Distance Piece
Distance Piece
Globagon manufactures distance pieces engineered to customer specifications, providing critical separation between the crankcase and cylinder assembly in reciprocating compressors.
Our distance pieces are designed to accommodate various frame configurations, pressure ratings, and sealing arrangements, while maintaining structural integrity and leak-tight performance. Options for single- or double-compartment designs are available to suit both lubricated and non-lubricated service.
Manufactured with precision machining and strict dimensional control, Globagon distance pieces ensure compatibility with related components and contribute to the overall reliability and cleanliness of the compressor system.
Working Principle
Distance Piece
The distance piece is a separable housing that connects the compressor cylinder to the frame and plays a key role in isolating internal components. Depending on the application, it can be open or closed and comes in single, double, or extra-long configurations, often with multiple internal compartments to suit specific process requirements.
In non-lubricated service, a longer distance piece is essential for keeping the piston rod area that enters the crankcase separate from the portion exposed to process gas. This separation prevents oil contamination in the cylinder and allows for the use of synthetic lubricants when needed, maintaining gas purity and system integrity.
In compressors handling toxic or flammable gases, the internal compartments of the distance piece help manage packing leakage by containing and directing escaped gas. Leaked gases can be vented to a flare system or controlled with a buffer gas, ensuring safe operation and minimizing environmental risk.
