Construction, function
Jet starter:
Jet starter are supplied as machines to be installed.
Completed with adequate accessory the screw compressor is ready for use.
The screw compressors are suitable for steady operation as well as for installation
in mobile compressor units. Operation in mobile units may be effected only when the
running gear is in idle position. Due to the travelling motion there would be a risk of
high damage to bearing and rotors when the compressor is in full operation. Oil leaka-
ges and interruptions in lubrication oil feed lead to further problems.
Operating oil filling quantity:
In the majority of cases, the directly driven Delta Screw units are not filled with oil
when supplied.
Please observe the machine‘s oil filling quantity and check the level using the mark-
ings on the sight glasses.
Drive:
An combustion engine drives the unit via a flexible coupling.
Shutdown of the compressor is effected by stopping the engine.
Resetting may be effected only after standstill of the compressor. Otherwise there will
be the risk of severe breakdown of machinery.
Intake side:
The intake side has to be equipped safely with accessory that meets the operation
requirements.
Please find the fineness of the air intake filter in the enclosed data sheet.
Please note also DIN EN 779 “Particle Air Filter for compartment air technology”.
The filter material has to be changed according to the pollution degree of the absorbed
air and according to the information stated in the maintenance schedule of the manu-
facturer of the aggregate.
Discharge side:
Due to the high compressed discharge temperatures, -> high surface heat emission in
the range of the discharge side can lead to stripping or bubble formation of the var-
nish. This process does not impair the compressor operation and is not considered as
defect of fabrication.
Due to the high compressed discharge temperatures --> high surface heat emission,
stripping or blistering of the varnish may occur in the vicinity of the discharge side.
However, this does not impair the useful properties of the compressor and does not
constitute a defect.
Instrumentation:
Operation without instrumentation, protective devices, etc. is not permitted.
