Inspections during operation
The following inspections have to be carried out during operation:
The liquid level in the reservoir must not be lower than the
minimum mark during operation.
Always turn the four-way cock until it hits the stop.
Intermediate positions are not permitted
Check whether pressure or vacuum builds up.
Pay attention to abnormal noises and leaks during operation.
If necessary, switch off VacuStar WR.
Drain the condensate at the safety trap. Vessel may not be
in a state of vacuum when condensate is drained.
Checking the operating data:
The speed must be between:
800…1600 min
-1
(WR 2500 / WR 3000) or
800…1300 min
-1
(WR 4000).
The cooling water outlet temperature (return flow to radiator)
may be max. 60 °C.
Check the positive working pressure at the pressure gauge
(permissible pressure see Tab. 4, page 15).
Check the operating vacuum at the vacuum meter
(permissible vacuum see Tab. 3, page 15).
CAUTION!
The following points must be observed when
explosive gases and gas mixtures are conveyed:
– Prior to every start of the VacuStar WR and
during operation:
– Check the process liquid levels
(VacuStar WR and reservoir).
– Check for leaks
– Listen for abnormal noise during the suction
process. Switch off the VacuStar WR if
necessary.
– Check the VacuStar WR at regular intervals
(daily) for signs of overheating and exceptional
deformations. If necessary, switch off the
VacuStar WR or do not put it into operation.
