Typical cross-section

Process Gas Compressor

Crankshaft are made of forged steel with built-in counterweights, for mediumand high powers.

SIAD Macchine Impianti can carry out the finite element calculations as well as the torsional analysis of the shaft-line.

Crankcase/Crankshaft

Specific design of TWIN BEARING at flywheel side

Advantages:

-limits the crankshaft deformation

-avoid high stress on bearings and crankshaft

Bearings

A range of more than 200 models.The result of a large experience.

Material : cast iron or steel

They are with or without liners.They are water cooled.

Cylinders

Designed for optimum balancing of rod load.Piston materials adapted to gas composition.Piston rod special treatments/coatings possible : * Plasma and detonation techniques. * Induction hardening.

Piston and Piston rod

Hydraulic tightening oncrosshead for medium andhigh power

Piston rod

Multipieces rings in individual casings. Floating elements are metallic(lubricated) or PTFE (oil free or mini lub). Automatic compensationof wear clearance. Possible venting buffer gas (N2), lubrication anddirect cooling.

Piston rod packings

SIAD Macchine Impianti is extremely strictin selecting automatic valves a/c to theprocess (valve dampening, gas speed,power losses, materials).

The valve assembly is designed to make impossible any inversion between the inletand the outlet.

Direct or reverse unloaders.

Valves

Our process compressors aredesigned to avoid impossible any introduction of oil into the cylinders andgas into the crankcase.

Double compartmentdistance pieces

- intermediate packing- wiper packing rings- oil slinger

Distance piece

Crosshead moves in a lubricated guide that can be easilydismantled.For medium and high power, it is fitted through removable shoes.

Crossheads

A wide variety of capacity controls systems allows to adaptcompressors to the real operating conditions.

1. Stepped control by suction valve unloading piloted by the outlet pressure2. Progressive capacity control (action on inlet valves)3. By-pass capacity control

4. Additional clearance pocket
