Definitions of Lubricants in High and Low Temperatures
Your lighter oils are mainly used when there is high speed and lower temp processes. The heavier oil are used for slower speeds and higher temp processes. The viscosity of the oil thickens in lower temperatures and in the higher temperatures it decreases the viscoity.
Flash point in a lubricant is when the temperature that is needed to heat it up to the point when it vapors or steams and it will flash into the flame. When it is this way, the heat is not enough to burn of the vapor that has formed.
Fire point is when it is at it’s highest temperature needed to form enough vapor from the lubricant you use to make it burn at a steady pace.
Pour point is when it will not pour out anymore because the temperature is so low. This is used in jobs that the temperature outside is so cold. That is the reason you have to be aware of the job and the temperature of elements to use the correct lubricants in order to do application. You will need to pick oils that have a high resistance to oxidation. Oxidation of an oil is when the acids form and will corrode a part made of a certain material. Oxidation is when oil and air mix and it may change any properties of another part you are using. Thus leading to a breakdown in your part and then you will not be able to finish the task at hand.
That is why you need to read labels or ask a dealer for information before starting your unit up.
