The emulsion pumping station system of fully mechanized mining face is equipped with 5 hydraulic pumps with 400kW motor power and is driven by a BPQJ2-(3×500,525)/1140 combined flameproof and intrinsically safe variable frequency starter. Among them, 2 power frequency pumps, 3 frequency conversion pumps, several auxiliary power frequency motors (including cooling fans, oil pumps, etc.). The intelligent liquid supply controller detects the pressure of the liquid supply pipeline in real time through the pressure sensor, and outputs the running speed of the variable frequency pump through PID operation to meet the demand of constant pressure liquid supply.
