TAILIEUCHUNG - ON THE LUBRICATION OF MECHANICAL FACE SEALS

If demagnitizing is required, place a resistance in series with a switch across two of the three phases. A voltmeter should be connected to these phases to monitor voltage (figure 10). Start with approximately 200 ohms resistance and close the switch momentarily with the unit running at rated speed. The measured voltage will drop when the switch is closed and then return to a value less than the original when the switch is opened. If the voltage is still higher than the rated voltage, close the switch again. If the voltage is dropping in very small. | ON THE LUBRICATION OF MECHANICAL FACE SEALS Harald Lubbinge The research project was sponsored by Flowserve . and was carried out at the University of Twente.
