Imported vacuum pump oil what is the common problem? - - - - - -

as the name implies, vacuum pump oil is used in the vacuum pump oil imports. In addition to the ordinary so-called lubricating oil lubrication, cooling and features, such as anti-oxidation, oil-water separation was more of an emphasis on low pressure, light component is far less than the conventional oil. In general, vacuum without oil and gas. Vacuum pump in this way, you will soon get a vacuum effect, rather than the extraction, vacuum degree will not always able to achieve. This requires a great deal of oil refining, should choose to synthetic oil when necessary. Imported vacuum pump oil, however, what is the common problem? How to change a vacuum pump vacuum pump oil?

imported vacuum pump oil, what is the common problem? Problems caused by vacuum pump oil change what method is there?

1。 discharge have injection phenomenon: come on too much, reduced the add input; Air intake should be added to avoid extraction for a long time.

2。 discharge fog: check the entrance and other parts for air leakage phenomenon.

3。 Low vacuum: other lightweight liquid is mixed in the pump chamber and oil. After changing the oil, pump should run normally for a period of time, to check whether all seal parts of pump with air leakage.

4, proofreading test instrument.

we are all familiar with the vacuum pump, they are widely used. How to save the import vacuum pump vacuum pump oil?

the following is the summary of the main points, for your reference.

( 1) The container with the gravity method is put below the oil drain port, tighten the oil drain screw, let the old oil in the vacuum pump automatically into the container. After discharge of the old oil, from the inlet into a clean vacuum water pump oil ( 100 ~ 500 ml) , flush the pump cavity, internal, and then start the vacuum pump runs for 1 minute, close vacuum pump, again from the injection of new oil. If you do not get the release of oil, should continue to use the new oil flushing, until clean. Then, the screw in the oil drain screw. Unscrewing, the screw on the oil hole, before will inject vacuum pump and vacuum pump oil, the oil level at oil tag line, and then screw on and screw.

( 2) The container with added pressure on the oil mouth, tighten the oil drain screw. Closed suction, at the same time open the vacuum pump, open the gas ballast valve, to cover part of the vacuum water pump exhaust outlet, so as to generate enough internal pressure, make dirty oil discharge quickly. Then, according to the method of cleaning inside the vacuum pump cavity, and new oil replacement.

in the end, replace the vacuum pump oil should also pay attention to the point:

( 1) Should pay attention to clean, prevent the dust mixed with vacuum pump;

( 2) Start the vacuum pump should not be too long, lest the exhaust valve slice beat is too dry and produce strong fatigue;

( 3) It is forbidden to use kerosene, gasoline, alcohol, etc. Do not remove the clean vacuum pump.

( 4) High oil temperature rise after the best oil change, in order to make the oil vacuum pump internal flow properly.
