Process and apparatus for controlling a pumping station and modular detection device for such a station. |
摘要 |
<p>The control apparatus for the pumping station comprises at least one pump driven by a motor, a sensor for the delivery pressure of the pump or for the level of a volume, and a minimum delivery flow rate sensor for the pump capable of triggering the stopping of the motor. The minimum flow rate sensor 12 is of a type which does not give rise to a substantial head loss when the pump is in normal operation and consists, for example, of an oscillating flap 14 submerged in the delivery duct 1 of the pump and connected to a switch 10% for controlling the motor, and capable of causing this motor to stop. Application to controlling the operation of pumps capable of undergoing abrupt variations in flow rate. <IMAGE></p> |
