|Flash point(open cup)||ºC||GB443-89|
|Demulsification value||New oil≤15min,running oil≤30min|
|Clean degree||≤6 Grade(NAS1638)|
|The quantity of inlet oil is less that of outlet oil when the machine runs stably||The primary filter is jammed,the resistance of the secondary filter is increased||Unpick and wash the filter,rearrange the process of the secondary purification.|
|Abnormal noise with oil pump on start or in running||1.There is air blockage in pump, producing noise.|
2.Oil not sufficient or too much air in oil pump.
|1.Adjust openness of inlet valve.|
2.Release air form oil inlet pipe.
|Heater if on but oil temperature does not rise.||1.Temp. sensor probe is out.|
2.Poor contact of heater.
4.Heating tube is burnt.
|1.Fix the probe;|
2.Check or replace
|Vacuum drops below the rated value||1.There is air leakage stemmed from poor joint or otherwise untightness.|
2. Insufficient oil in vacuum pump
3. Dirty oil in vacuum pump
4. Air release valve or other part of vacuum pump is broken.
5. Vacuum meter does not work.
2.Replenish oil to mark line
|It is difficult to start vacuum pump||1. There is foreign matter in pump|
2. Belt is too loose or tight or coupling goes wrong.
3. Poor power line wiring or motor goes wrong.
|1.Check ,esp. whether there is any piece of broken copper gauze of air inlet in pump.|
There is oil spray from air outlet of vacuum pump.
|1.There is too much oil in pump;|
2.Purified oil contains too much moisture, vaporized content and foam;
3.There is too much oil in vacuum tank.
|1. Reduce oil to a little below the centerline of oil gage.|
2.Open ballast valve to reduce vacuum and raise oil temp.
3.Stop machine, start oil-discharge pump to lower oil level and restart vacuum pump.
|Purified oil is not satisfactory|
|The outlet oil is less|
