Title:
FAULT PROTECTION FOR A PUMP-MOTOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2019/152959
Kind Code:
A3
Abstract:
A fault control protects a pump-motor assembly from monitored faults. The pump-motor assembly includes an electrical motor mechanically coupled to a pump. The fault control determines a speed of the motor. If the speed is determined to be less than a minimum speed, the fault control generates a fault signal to affect the operation of the motor. The fault control can also determine if a phase of the power provided to the motor is missing based on vibrations sensed by a vibration transducer. The fault control can also determine temperature faults based on signals from two thermocouples, including determination of loss of inlet or discharge flow.
