How much do you know about the "oil film strength" and "oil film thickness" of engine oil?

How much do you know about the "oil film strength" and "oil film thickness" of engine oil? Regarding the strength of the oil film, I read the information and it is defined as follows: The oil film has the ability to resist pressure without breaking, and to maintain sufficient oil film thickness to prevent direct contact with the friction surface. What is oil film strength? In terms of definition, the difference between oil film strength and oil film thickness is well stated. A parameter indicating the strength of the oil film is called "HTHS". This parameter is the apparent viscosity of the oil through the capillary viscosity test at 150°C, which is the dynamic viscosity. Because HTHS reflects the adhesion ability of the lubricating oil between the piston and the cylinder and between the shaft and the bearing bush, it is related to the oiliness agent or polar agent added to the lubricating oil. Many people call it "oil film strength". It is understood that the strength of the oil film is vivid and accurate. What is the oil film thickness? The oil film refers to the protective film formed by the oil in the engine, which will exist at all times. Since there is a film, there will be thickness. How is the thickness of the oil film measured? It can be simply understood as: high viscosity oil means thick oil film, thin oil means thin oil film. Why do you say that? Let's first look at the definition of viscosity. Viscosity is the internal resistance of the fluid, so the viscosity of lubricating oil is usually the thi
The difference between hydraulic oil and anti-wear hydraulic oil, can it be replaced?
2021 / 04 / 07
Hydraulic oil and anti-wear hydraulic oil look very similar, which has caused many people to be confused between the two. Today I will tell you the difference between hydraulic oil and anti-wear hydraulic oil. The difference between hydraulic oil and anti-wear hydraulic oil 1. Different composition: Hydraulic oil = refined base oil + anti-oxidant and anti-rust additives. Anti-wear hydraulic oil = hydraulic oil + anti-wear additives, etc., with better lubrication effect. 2. Different applications: Hydraulic oil: In addition to being used in the medium and high pressure hydraulic systems of various hydraulic pumps, it can also provide lubrication for medium-duty industrial gears. Anti-wear hydraulic oil: more emphasis is placed on the hydraulic system of heavy-duty, medium-pressure, high-pressure vane pumps, plunger pumps and gear pumps. 3. The use time is different: Hydraulic oil: There are many types, and the use time of each type is different. Anti-wear hydraulic oil: The use time of high-
Is there a difference between gear oil and automatic transmission fluid (ATF)?

This is a problem that many car owners are confused, is there a difference between gear oil and automatic transmission fluid (ATF)? The simplest explanation is that gear oil is usually used in manual transmissions, while transmission oil is generally used in automatic transmissions. However, as with car lubricants, there are exceptions to this rule. In order to fully understand the differences between them, we must first study the main differences between gearboxes and automatic transmissions. Manual Gearbox The manual gear is based on a two gear shaft system. After the user inputs through the clutch and the shift lever, the gears will mesh together. This means that when two moving objects are gathered together, the manual gearbox will generate a lot of heat and friction. Therefore, the gear oil must be able to make these gear transitions as smooth as possible to prevent damage to them when the components are moved. Gear oil should have good anti-wear, load-resistant performance and suitable viscosity. In addition, it should also have good thermal oxidation stability, anti-foaming properties, water separation properties and anti-rust properties.
