Challenge
When starting turbine pumps in hydroelectric power stations, water must be removed from the pump chamber to enable a safe and unloaded start-up. This requires a reliable compressed air supply at a sufficiently high pressure.

Solution
Reciprocating compressors generate the required compressed air and enable the system to be drained in a controlled manner.

The compressors used are designed for high pressures and ensure a stable supply even under demanding operating conditions.

Implementation in Austria
A reciprocating compressor is used in a hydroelectric power station to compress atmospheric air to up to 36 bar. The compressed air is used to remove excess water from the pump chamber and to relieve the load on the turbine pump during start-up.

The system is designed for reliable operation and ensures consistent performance in daily use.

Results

• Safe and unburdened start-up of the turbine pump
• Reliable compressed air supply up to 36 bar
• Stable operation even under demanding conditions
• Efficient drainage of the pump chamber
