Inspections during operation
The following inspections have to be carried out during operation:
Prior to every start-up and during operation, the oil level and the
coolant level must be checked and topped up if necessary.
Open shut-off devices. Always turn the four-way cock until it hits
the stop. Intermediate positions are not permitted
Switch on drive and check whether pressure or vacuum are
created.
Pay attention to abnormal noises and leaks during operation. If
necessary, switch off VacuStar W.
Drain condensate at the condensate and safety traps. Vessel
may not be in a state of vacuum when condensate is drained.
Checking the operating data:
The speed must be between 1000…1,500 min
-1
The cooling water outlet temperature (return flow to radiator)
may be max. 60 °C.
Check positive working pressure at the pressure gauge
(permissible pressure refer to rating plate).
Check the operating vacuum at the vacuum meter (permissible
vacuum refer to rating plate).
The compression end temperature at 20 °C suction temperature
may not exceed the following values:
–
140 °C at 400 mbar operating vacuum
–
120 °C at 0.5 mbar excess pressure
