SCFM Introduces the Vilter Single Screw Compressor
After Several Years of working with the Vilter Single Screw, in Mid 2004 SCFM signed an Exclusive Distributorship Agreement for the Natural Gas Industry.
What it does best is Run! Run! Run! – almost maintenance free. Because of the Superior & Unique Design of this equipment, many of the existing placements have been in service for over 5 years without experiencing any maintenance downtime except for routine PM’s.
Can your current compression equipment make this claim?
The Single Screw History
First C-P design patented by Bernard Zimmern in France in the early 1960’s. First mass marketed in Japan in 1973. Now over 400,000 single screw compressors are utilized in air, refrigeration and process gas applications world-wide. The earliest single screw compressors were used in air service only.
Why Use the New SCFM/Vilter
Single Screw Compressor
When the new unit applications fit, the SCFM/Vilter Single Screw Compressor is simply the Best Compressor on the Market Today. It has the Lowest Total Life-Cycle Cost and is one of the most efficient.
– Tooth Area Decreases as Pressure Increases
– Easily Defined Loads – Inherent Low Bearing Loads
Design Features
Typical Rotor Assembly has:
– Pair of Angular Contact Bearings to Axially Locate the Assembly
– Eleven Teeth – Rotate at 6/11 of Driveshaft Speed – PPS Composite Material
Compression
Operation at 3600 RPM Results in 21,600 Simultaneous Compression Strokes Per Minute Smooth Operation with Low Torque and Pulsation Levels
源自文库
Single Screw Design
Main screw utilizes six helical grooves.
Gate rotors utilize eleven teeth.
Gate rotors turn at 6/11 of main shaft speed.
Results in 43,200 compression “strokes” per minute at 3,600 RPM. Parallex™ slide system for capacity and volume ratio control, resulting in peak part-load efficiency.
Process Applications
Wellhead Compression Gas Gathering LNG Boil Off Fuel Gas Boosters (Methane, H2 Mixtures) Compression (Propylene, CO2, CO, N2 ) Digester Gas Flare and Vent Gas Landfill Compression Recycle Gas
Design Features
Balanced Loading of the Main Screw
– Radially Balanced – Axially Balanced – Resulting Low Bearing Loads
Design Features
Gaterotor Loading
Major Components
Main Screw
– Six Helical Grooves – Cast Iron Material
