Automatische Anpassung des Stellbereiches eines Druckregelkreises in Mehrpumpenanlagen |
摘要 |
<p>Two parallel circulation pumps (11, 21) circulate variable quantities in a pipeline system. A microprocessor (4) controls the revs of at least one pump in dependence on the detected feed pressure on the pressure side (9), provided by a sensor (5). The microprocessor automatically adapts the lower setting limit in dependence on the actual or required feed pressure, by discrete activation or de-activation of at least one of the pumps.</p> |
