Operating limit values
Operating range
Avoid the following conditions for the liquid ring pump:
•
Combination of several limit values
•
Starting frequency (
≤
10 1/h)
If more than one operating limit value is reached, consult the manufacturer for operating conditions.
Ambient conditions
• Temp
erature
between -20°C and +40°C
•
Air humidity
maximum 60%
•
Installation site
dry
If temperatures are below +5°C, measures must be taken on the operator's side to prevent frost damage.
Conveyed product
General
•
Avoid the flow of several phases in waves or in plugs.
Operating pressures
•
Suction pressure:
e
operating fluid
(vapour pressure of the operating fluid) + 20 mbar
•
Compression overpressure:
≤
0,3 bar
•
Difference between suction and exhaust side: 200 mbar to 1 1 00 mbar
In case of non-condensed gas pure steam transport, supply the suction side according to the plant design
Inlet temperature
•
Saturated inlet temperature
≤
100°C
•
Dry inlet temperature
≤
200°C
