SIAD Macchine Impianti new API 618 process gas compressors range
2
Scope Product range (page 1 of 2)
Reciprocating horizontal balanced compressors Maximum power : up to kW Maximum Pressure : bar Maximum Capacity : m3/h
3
Product range (page 2 of 2)
4
Compressor configuration
Balanced, opposed 2 C.R. horizontal Balanced, opposed 4 C.R. horizontal
5
HPX model Max 1000 kW - Max rod loading : N 2 to 4 connecting rods
6
HD model Max kW - Max rod loading : N 2 to 4 connecting rods
7
Operational data (page 1 of 2)
Compressed gas : All gases Gas inlet dew point : Bone dry Nitrogen Gas inlet temperature : successful experience up to -150°C (-238°F)
8
Specialisation in oil free
Operational data (page 2 of 2) Specialisation in oil free Number of stages : up to 6 Outlet pressure : bar (1450 psi) in oil free application bar (2900 psi) with mini lubrication and PTFE type rings bar (5000 psi) with full lubrication and metal rings Minimum pressure ratio : around 1.2

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
