Drive Coupling - Chicago Pneumatic CPVS 20 Product Description

CONTROL DEVICES
- Minimum pressure check-valve
- Rapid discharge for quick, automatic depressurization system to ensure a reliable
idle restart without foaming the lubricant or damaging components
- Visible oil level via sight glass on the separator tank
- Gauge for the reading of the air-oil separator pressure
- Pressure transducer for the setting and the reading of the operation pressure
- Thermal probe for the control and the reading of the temperature value of the air/oil
mixture delivered to the airend
LUBRICATING SYSTEM
The CHICAGO PNEUMATIC CPVS 40-250 is supplied with an 8,000 synthetic blend
lubricant. Within the compression unit, the air and lubricating oil are mixed together
and sent to the oil/air separation system in order to reduce the oil carryover in
suspension. The oil and the compressed air are separately cooled by means of a
final air and oil cooler. It is kept in constant transit by the pressure difference of the
compressed air circuit, thereby avoiding the use of power consuming oil pumps.
Proper filtration and effective cooling ensure optimal operating conditions for the oil
and grant performance longevity of the compressor. The oil has three main
functions:
- Lubrication of the airend and reduction of frictional losses
- Cooling of the airend by transmitting heat from the compression elements
- To provide a seal between the rotors of the airend

DRIVE COUPLING

The gear drive used on the CHICAGO PNEUMATIC CPVS 40-250 compressors
requires no maintenance and no periodic change. A rigid housing is fitted to
guarantee perfect alignment between the motor and the airend, this combined with
the flexible coupling reduces vibration and extends the life of the compressor. The
coupling is also a sacrificial piece that provides added protection to the airend and
motor. Should the airend lock-up for any reason, the coupling will break, thereby
preventing the motor from burning-up.
THE LATEST EVOLUTION OF THE ASSYMETRICAL PROFILE AIREND
Combining proven technology with advanced materials and production methods, we
have developed a new airend that sets the standard for efficiency and reliability. The
oil flooded asymmetrical screw type element ensures peak performance with no loss
in efficiency throughout the life of the compression element.
COOLING AIR
Cooling air is drawn in at high level to ensure the minimum amount of dust
contamination enters the package. The inlet baffles optimize the air flow entering in
the unit allow the compressor to be installed next to a wall which lowers the
installation space required and saves on maintenance costs. The baffles also
minimize the velocity of cooling air entering the package which prevents pre-filters air
