3.2 Description
ROBOX SCREW is a compressor compact unit based on an innovative screw compressor with all the accessories needed for the
correct operation descrivbed below (refer to the figures 1A and 1B at pages 30 and 31):
1) Compressor
The compressor has two rotors with screw coniugate lobes with special ROBUSCHI profile PTFE coated supported by roller
bearings and syncronized with helicoidal gears
Bearing and gears lubrication is carried out by lubrication by forced oil circulation by an oil pump coupled directly on the
compressor drive shaft, oil filter and oil/air heat exchanger
2) Suction line
The compressor suchs the atmospheric air by mean a suction silencer integrated in the unit base frame.
In the base frame is integrated also th suction filter in such a position to facilitate the filter maintenance operation
When the compressor suchs the gas from a closed circuit it is possible insert a starting strainer instead the filter element
3) Discharge line
The compressor discharges the gas in the circuit by mean a discharge silencer directly flanged on the compressor nozzle, an
elastic metallic connector and a non return valve.
On the discharge silencer is installed a safety relief valve set at the maximum design pressure of the discharge silencer to
protect the discharge components from high overloads induced by the discharge pressure.
On the dishcarge line it is possible to install the starting valve VSM to allow the reduced load start in the plant where there is
a static counterpressure.
4) Drive
The compressor is driven by an asyncronous electric motor via a special POLY-V or toothed belt transmission protected with
proper belt guard.
The unit is delivered without the electric supply cabinet for the main motor. As an option can be supplied the auxiliary electric
cabinet which controls the noise enclosure fan controlled by the electronic device SENTINEL2 or Sentinel PRO.
On request it is possible to deliver an electric supply cabinet with all the safety devices and following the custumer
specifications
5) Instrument
The unit is provided complete with manometer for monitoring discharge pressure, vacuometer to monitor inlet filter
depressure and oil lube pressure switch.
On request unit is provided with the electronic device SENTINEL2 to monitor the main operating parameters on of the
compressor.
If the unit is delivered without the elctric supply cabinet the customer has to wire SENTINEL2 to the electric supply cabinet to
grant the main operating parameters monitoring and the detection of the fault/alarm, if the unit is delivered with the electric
supply cabinet the SENTINEL2 is wired directly by ROBUSCHI
