WESSEL Generator control TYP FC1-3G
Descripton
The electrohydraulic drive control was originally developed to supply the drive of a power generator. However, it can also be used for other drive systems where precise speed control is required. Systems are designed for power ratings of 13, 20 and 30 kW.
The speed of the connected load is constantly controlled via a speed signal generated by the load. Load changes of the consumer are compensated for by dynamic damping of the hydraulic circuit. The system is optimized for energy savings compared to conventional systems
Applications
For single-acting rotary drives that are operated at a precisely controlled, constant speed and must be actively damped during load changes.

1 +3 3-way Flow Control Valve with pressure cut off (Pressure Compensator)
2 controlled mainvalve fort he supply of the hydromotor
4 Pressure reducing valve. Generates piloting pressure (30 bar) for the supply of the proportional valves 5 and 6
5 Electrical-proportional piloting valve for the return spool (7)
6 Electrical-proportional piloting valve for the inlet spool (2) The valves 5 and 6 are operated by the electronic control inside a regulating circuit
7 controlled mainvalve for the throtteling of the hydromotor´s return line
8 safety pressure valve fort he hydromotor
9 anti-cavitation valve fort he hydromoto
