Design The fully automatic pressure booster system is equipped with two to six vertical
variable speed high-pressure centrifugal pumps (4) for pumping the fluid handled to
the consumer installations in the set pressure range.
Function Motor-mounted frequency inverters (2) control and monitor two to six high-pressure
pumps (3). Each pump set is operated on a motor-mounted variable speed system
(frequency inverter) and controlled so as to ensure a constant discharge pressure of
the pressure booster system. As the demand increases or decreases, peak load pumps
are started and stopped automatically.
As soon as the demand increases again after one pump set has been stopped,
another pump set which has not been in operation before is started up. When the
last pump set has been stopped and the demand increases again, the next pump set
in line is started up. The stand-by pump is also included in the alternating cycle.
The actual pressure is measured by means of an analog pressure gauge (pressure
transmitter) which is monitored by integrated broken wire detection (4-20 mA). In
the standard setting, the pressure booster system starts up and stops automatically.
The pump sets are started and stopped as a function of demand. Variable speed
control reduces the frequency of starts of the pump sets in parallel operation. If a
pump set that is in operation fails, the next pump set is started up immediately. If the
demand drops towards 0, the pressure booster system slowly runs down to the stop
point. A fault message can be transmitted via volt-free contacts, e.g. to a control
station. The operating status is displayed via LEDs.
