1..screw air compressorlubricating oil
a) cooling effect
as a coolant, it can Effectively control the temperature rise caused by the compression exotherm;
b) Lubrication
As a lubricant, it can form a lubricating oil film between the rotors;
c) Sealing effect
As a sealant It fills the gap between the rotor and the housing and between the rotor and the rotor.
d) Noise reduction
The injected oil is a viscous fluid that absorbs and dampens sound energy and sound waves. Generally, the noise can be reduced by 10 to 20 dB (A) after injection. 2. Viscosity
is an indicator of the oiliness and fluidity of the oil. Common viscosity indicators are dynamic viscosity and kinematic viscosity. 3. Dynamic Viscosity
Two oil layers each with an area of ​​1 cm2 and a distance of 1 cm away. When one of the oil layers is at a speed of 1 cm/s to the other oil layer The resistance generated during relative motion is the dynamic viscosity. The unit is Pa·s, commonly used unit mPa·s (centipoise). 4. Kinematic Viscosity
The ratio of the dynamic viscosity of a liquid to its density at the same temperature is called the kinematic viscosity. Unit m2/s, commonly used unit mm2/s (centimeter cSt). 5. Coagulation point
The maximum temperature at which the oil stops flowing under the specified cooling conditions. It is an important quality indicator for the low temperature fluidity of lubricating oils. Both the pour point and the pour point are indicators of the low temperature fluidity of the oil. There is no principle difference between the two, but the measurement method is slightly different. Generally, the pour point is higher than the freezing point of 2-3 °C.
6. Pour point
The pour point and the pour point are indicators of the low temperature fluidity of the oil. There is no principle difference between the two. The method is slightly different. Generally, the pour point is higher than the freezing point of 2-3 °C. 7. Flash point
The oil is heated under the specified experimental conditions to raise the temperature, and some of the components evaporate or decompose to produce flammable gas. After a certain temperature and mixed with air, the lowest temperature at which a flash can occur when in contact with the flame is called the flash point.
8. Antifoaming
refers to the size of the foaming volume and the speed of defoaming when the air is introduced into the oil or when stirring. performance. In actual use, the lubricating oil is mixed into the oil due to the action of oscillation, agitation, etc., so that the formation of bubbles causes the fluidity of the lubricating oil to deteriorate, the lubricating performance is deteriorated, and even the gas resistance affects the oil supply, so that the machine parts Lack of lubrication, wear and even sintering
9. Emulsifying resistance
The anti-emulsification property of oil refers to the prevention of oil emulsification, or emulsification at one time. However, it can be rapidly decomposed by the static oil.
