Process Gas Compressor
Typical cross-section
Crankcase/Crankshaft
Crankshaft are made of
forged steel with built-in
counterweights, for medium
and high powers.
SIAD Macchine Impianti
can carry out the finite
element calculations as
well as the torsional
analysis of the shaft-line.
Bearings
Specific design of TWIN
BEARING at flywheel
side
Advantages:
-limits the crankshaft
deformation
-avoid high stress on
bearings and crankshaft
Cylinders
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.
Piston and Piston rod
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 rod
Hydraulic tightening on
crosshead for medium and
high power
Piston rod packings
Multipieces rings in
individual casings.
Floating elements
are metallic
(lubricated) or
PTFE (oil free or
mini lub). Automatic
compensation
of wear clearance.
Possible venting
buffer gas (N2),
lubrication and
direct cooling.
Valves
SIAD Macchine Impianti is extremely strict
in selecting automatic valves a/c to the
process (valve dampening, gas speed,
power losses, materials).
The valve assembly is designed to make
impossible any inversion between the inlet
and the outlet.
Direct or reverse unloaders.
Distance piece
Our process compressors are
designed to avoid
impossible any introduction
of oil into the cylinders and
gas into the crankcase.
Double compartment
distance pieces
- intermediate packing
- wiper packing rings
- oil slinger
Crossheads
Crosshead moves in a lubricated guide that can be easily
dismantled.
For medium and high power, it is fitted through removable
shoes.
Capacity control (page 1 of 2)
A wide variety of capacity controls systems allows to adapt
compressors to the real operating conditions.
1. Stepped control by suction valve unloading piloted by the
outlet pressure
2. Progressive capacity control (action on inlet valves)
3. By-pass capacity control
4. Additional clearance pocket

- remote control
Oil circuit-frame oil lube system
- Main oil pump driven by crankshaft
- Prelube pump for starting and stand by
- Design conform to API 618
