Common troubles of vacuum oil filter
Failure cause, elimination method, vacuum degree can not be reachedTechnical standard 1, filtered oil contains more water, vacuum pump exhaust gas, excessive steam;2, due to the use of altitude, not in the standard atmospheric pressure, the impact of changes in vacuum;3 、 vacuum oil low oil level line in vacuum pump;
The pressure is greater than 0.3MPa 1, the tubing is too long, the oil level is too high, the oil outlet is small or the pipe is too small;2, filter oil absorption has many impurities. 1, change the working environment;2. Replace filter paper or filter core. Vacuum pump starting oil injection 1, filtered oil, water content, oil floating upward, was sucked into the vacuum pump, vacuum pump oil level rise;2, vacuum pump gasket shift or damage. 1, the vacuum oil shall not be higher than the oil level line;2, overhaul. Oil control or no temperature 1, oil temperature and thermometer does not match;2 、 heater burn out or line break or contact arm end anastomosis. 1, adjust oil control;2 、 maintenance line change heater. No pressure out of the oil pump
5, the sealing gas leak at each connection;6, wearing parts of vacuum pumps. 1, is a normal phenomenon, you need to filter many times;2, it is normal to raise the temperature of the oil, so that the water evaporates;3. Increase the vacuum pump;4, need to replace the new oil;5, inspection and maintenance;6. Replace the wearing parts. Under normal working conditions
