Control of fire water
Thread Content
There are currently two voltage-stabilizing pumps, each with a capacity of 2 kW; they share one inverter and operate in a one-in-use-one-backup configuration. There are also fire pump units with a capacity of 220 kW, operating in a two-in-use-one-backup setup. The pressure in the pipeline system is to be maintained at 0.8 – but how is this controlled? There is no control mechanism for it
The installation of fire protection facilities requires blueprints and must be registered. So, check the design drawings.

The system is quite large. 2. The flow rate of the pressure stabilizing pump is definitely too low; if it operates normally, it basically cannot be stopped. Normally, fire protection systems determine the operating conditions of various pumps by adjusting the pressure in the piping network to specific values or through fire alarm signals.
