PUMP SUCTION PRESSURE LIMITING SPEED CONTROL AND RELATED PUMP DRIVER AND SPRINKLER SYSTEM
摘要
<p>A building sprinkler system includes a pump that feeds a plurality of sprinkler heads. A driver is operatively connected to the pump for driving the pump. A speed control is responsive to suction pressure at a suction side of the pump. The speed control is configured to reduce driver speed when the suction pressure falls below a set threshold pressure value to maintain the suction pressure above the set threshold pressure value.</p>
