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
