Dual Vent Seals with Stainless Steel Rings
Lubricantion of Gears and Bearings
Our patented Super Rotor profile is the most efficient in the in
dustry. The
machined forged steel rotor sets have the most precise tolerances in the industry. FDA
approved rotor coating further increases volumetric efficiency. In addition, the new
profile provides 20% more displacement per revolution thus lowering rotor speeds and
increasing bearing life.
Dual Vent Seals with Stainless Steel Rings
Each shaft seal consists of floating stainless steel rings and an oil labyrinth inserted between the rotor chamber and the bearings.
 |
Each seal is buffered by gas from the compression chamber which is purged to atmosphere ensuring that no lubricating oil or its vapor can enter the compression chamber. |
Lubrication of Gears and Bearings
Lubrication
prior to start-up, during operation and after shutdown is supplied by an independent motor
driven gear pump. Compressor operation is not allowed until oil pressure is established.
During the coast down period the oil pump continues to provide full lubrication until the
compressor stops. This design increases gear and bearing life and is not standard on
competitive units.
The efficient and simple capacity control system is a load/unload type with a direct operating disc valve and no discharge air recirculation. During unloading the bleed-off air is released to atmosphere through a muffler. This eliminates the need for a bleed-off cooler and the associated problem of condensed moisture entering the inlet of the compressor. The control is an electro-pneumatic device. No oil, hydraulic cylinders, or rolling diaphragms are used in the operation of this valve.
This control provides energy efficient operation while eliminating adjustments and minimizing maintenance. When the compressor unloads the brake horsepower drops to approximately 18% of full load, significantly reducing overall energy cost. The compressor will shut down after operating unloaded for a period of time and will automatically restart on pressure demand.
