  • Method to control out pumping from a sewage pump station
    Patent number: 6203282
    Abstract: A method to control stops of an intermittently operating electric motor that drives a submersible pump arranged in a pump station for sewage water, wherein starts and stops of the motor depend on the water level in the pump station or on any other electric parameter possible to measure, and where a stop of the motor is initiated when the water level has gone down to the upper part of the motor. The method involves the steps of selecting intervals for pumping down to a level below that of the upper part of the motor where the pump starts sucking air, and pumping down to the lower level at each of the selected intervals until the pump starts sucking air.
