Automation of the start-up of the screw pumps of the rainwater pumping station

Control cabinet system for automation of rainwater pumping station

In the rainwater pumping station are installed two independent screw pumps for drainage of rainwater. First softstarter SINAM 400/191 starts the pump motor #1. Second SINAM 400/191 starts the #2 pump motor. The control system for the rainwater pumping station automation includes controls for automatic control of pump switching, manual mode or manual mode to the level. The rainwater height is sensed by a level switch, and the control system in automatic mode decides which pump is to be operated while maintaining the pump alternation condition. In all control modes, the critical level level is sensed by the vibrating fork level switch, and in automatic mode, at the critical rainwater level, both pumps are switched on at the same time.

The display has 4 screens showing total data, level height, softstarter status information, setting options, etc. In manual mode, it is possible to manually operate the start / stop buttons. At the critical level of the rainwater, it is possible to select the control of both pumps at once. In the event of a power failure, the control system has backup power, meets safety requirements, and sends individual information about softstarter, level, backup power to the JABLOTRON JA80 control panel and the entire system is visualized locally on the intranet. In the future, the Control System will also manage the system for automatic lubrication of individual pumps #NOFRONTPAGE#
