Rotary vane vacuum pumps to use specific lubricating oil? - - - - - -

many people will ask this question: can rotary-vane vacuum pump are used car engine oil? The answer is not. So why rotary-vane vacuum pump application specific lubricating oil? Below small make up to analyze.

some users of the rotary-vane vacuum pump in order to save cost and application of general motor oil instead of the application of vacuum pump for oil, in fact, this to a certain level not only promoted the application of the vacuum pump, maintenance costs, could also serious harm to the vacuum pump.

1, vacuum pump oil has certain viscosity, viscosity of height decision the airtight sex of the vacuum pump, the viscosity is too small, is not so good in sealing; Viscosity is too high, will increase the friction of leaves in the pump and engine block, immediately RunHua effect worse, in addition, the rotation of the rotor of the motor may be more and more difficult, the work of the motor pressure may rise, will also become more and more high oil temperature. Oil temperature rise will accelerate the pump oil emulsification degree, really harm the height of the vacuum value.

2, vacuum pump oil physical property is more stable, moisture content, water-soluble acid, insoluble alkali and other residue composition is much, much smaller, used for oil energy consumption level of monarch from several conversion problem of vacuum pump oil and ensure cleanliness in the pump.

3, vacuum pump oil full product vapor pressure, lower volatile light fraction as far as possible. If it is the general vacuum pump oil or car engine oil is very easy to evaporate, the application of vacuum pump for oil is often encounter to the situation in oil.

can see from the above aspects, the reasonable application of vacuum pump for oil can avoid pump oil emulsification and carbonization on the elements of vacuum pump is not good, from the source to solve the difficulty of the vacuum pump maintenance coefficient, could improve the vacuum pump.

and the whole process of application of vacuum water pump, should often check, the application of vacuum pump for oil pump oil emulsification, carbonization, with is not a residue or unknown liquid and its vacuum pump oil suddenly increase, etc. , are sure to as soon as possible to carry out the conversion vacuum pump oil, the conversion of additionally make sure is the same specifications 100 special vacuum pump oil, to ensure the normal application of vacuum pump.
