Trip speed compressor
WebMost problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost … WebThe compressor is brought to the rated speed and then runs for 30 minutes to get lube oil temperature, viscosity, bearing temperatures and vibration amplitudes stabilized.After …
