Equilibrium operation and soft start-up technology of high-power pump based on PLC

Aiming at the problem of drainage pump station for more than high-power pumps impacting largerly the power,the operation programe was determined using S7-200 PLC as a controller,combining the soft starter ATS48C41Q and comparing the running time of equipment,thus a soft start dragging 4 blanced operation and soft-start pump was achieved.This technology reduces the cost and improves efficiency,having value for promotion.
