Liquid Ring Vacuum System Troubleshooting Guide
system is:
WE SUGGEST YOU CHECK THIS:
A. Low line voltage. Power consumption is a function of line voltage and amperage draw (P=IxE). If the facility's line voltage dips below required levels, the pump and motor may draw excessive amps, resulting in excessive heat and motor trip out.
B. The motor starter could have a defective contactor. Such a situation would not allow the contactor to handle the proper level of amperage, causing it to interrupt power to the motor prematurely.
C. There could be a loose wire in the main power feed or the circuit to the pump motor. Loose or inadequate wire connections will cause excessive resistance and subsequent high amp draw.
D. Heavy rust or scale buildup in the pump. If the pump is old or the seal water contains significant mineral deposits, the pump may build up heavy scale or rust. This will present a heavy load on the pump's motor and could cause it to trip out.
E. A weak motor. If the pump's motor is old, it could become weak due to numerous occasions of heating and cooling. The motor may need to be replaced.
F. Excessive sealing water in pump or excessive liquid carry over to the pump's inlet. Too much liquid in the pump will cause high amp draw and could damage the pump.
