9. Process Gas Compressor
Typical cross-section

10. 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.

11. Bearings Specific design of TWIN BEARING at flywheel side Advantages:
limits the crankshaft
deformation
avoid high stress on
bearings and crankshaft

12. 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.

13. 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.

14. Piston rod
Hydraulic tightening on
crosshead for medium and
high power

15. 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.

16. 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.

17. 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

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

19. 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
Capacity
steps

20. Capacity control (page 2 of 2)
5. Capacity control by additional clearance pocket
* manual * automatic
- local control - remote control

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