Method to control source of vacuum in vacuum sewage system Method to control source of vacuum in vacuum sewage system / 2509844
Vacuum, i.e. pressure level, and efficiency of the system is maintained and controlled, whilst controlling the speed of rotation of a source/sources of vacuum measured by number of rotations per minute. The source of vacuum has a liquid-ring screw pump driven by an electric motor. Number of rotations per minute of each motor in the system is controlled by means of a programmable logical controller. The controller is programmed to maintain the one first source of vacuum as connected, until it reaches the specified maximum number of rotations per minute, with subsequent connection of the next, second, source of vacuum, if the vacuum system requires higher efficiency of pumping. The programmable logical controller may also be programmed to control the number of rotations per minute for each source so that sources operate with identical speed of rotation in the range from least or highest number of rotations per minute depending on the required vacuum, but with connection of the additional source of vacuum, when higher efficiency is required.
