Woodward 9906-732
Product Name: 723PLUS Digital Speed Governor Controller (Mud Pump, Industrial Drive Engine Firmware)
Product Introduction: 723PLUS low-voltage hardware body, preloaded with industrial non-power-generation drive firmware. For reciprocating engines driving non-generating loads, such as mud pumps, water pumps, transmission equipment. Only performs constant-speed process drive, with no generator grid-connection logic.
Detailed content
Technical Specifications: Hardware I/O electrical specifications same as 9906-719; firmware removes generator paralleling logic, strengthens process constant-speed control.
Functional Features:
-
Local / remote analog setting of process target speed
-
Load overload speed reduction protection logic
-
Process interlock discrete shutdown input
-
Fault diagnosis, event recording, parameters saved after power loss
Application Scenarios: Oilfield mud pump driving diesel engines, large industrial water pumps, fixed power main engines for construction machinery.
Performance Parameters: Hardware environment and electrical metrics same as 9906-719.
Material Composition: Metal sheet metal enclosure, industrial wide-temperature PCB components.
Structural Features: Hardware body completely identical to 9906-719.
Working Principle: Receives process given speed, collects engine speed for PID closed-loop, outputs signal to drive fuel actuator, maintaining constant process speed of equipment, receives external interlock signal to execute protection shutdown.
Installation Requirements: Control cabinet flush-mount installation, away from engine body vibration, all analog signals use shielded twisted pair; 24 V DC stabilized power supply.
Usage Precautions: This model firmware has no generator paralleling function, cannot be used in generator set grid-connection scenarios.
