What is the kinematic viscosity of No. 46 anti wear hydraulic fluid at 10 degrees Celsius

What is the viscosity of this hydraulic oil, the user does not need to analyze and study, the user only needs to know, what grade of hydraulic oil is suitable for use in what kind of ambient temperature. If oil viscosity analysis is required, it can only be sent to a unit with testing equipment for testing. You're right?

The size of the oil number is related to the thick viscosity of the hydraulic oil, the small size is thin, the large size is thick, and the thin hydraulic oil is used in a place where the ambient temperature is relatively low, which is more in line with the working principle and physical principle, and the same way, 46 is large, thick, suitable for equipment with high ambient temperature, annoying working frequency, and easy to heat up the hydraulic oil. Your current use temperature is about 10 degrees, obviously the hydraulic oil is bigger, please choose 32, I believe you have understood.

So the viscosity index of each oil is different, and it will be very different at 10 degrees, but it will be about 46 at 40 degrees, and if you are afraid of using it in the northern winter, the pressure is insufficient, you can change it to 32 and look at it. However, if the summer of 46 is normal, the winter is basically normal, and 10 degrees is not a very low temperature.

The kinematic viscosity is generally measured at 40 degrees, and the 10 degrees are not very clear

kinematic viscosity, 40

The density is between 860 870kg m3.

1. Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy, which plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system.

2. For hydraulic oil, first of all, it should meet the requirements of the liquid viscosity of the hydraulic device at the working temperature and the starting temperature, because the viscosity change of the lubricating oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, and also requires that the viscosity temperature performance and shear stability of the oil should meet the various needs of different uses.

3. There are many types of hydraulic oil, and the classification methods are different, for a long time, it is customary to classify them by use, and there are also classified according to the type of oil, chemical composition or flammability. These classification methods only reflect the earning of oil products, but they are not systematic and difficult to understand the interrelationship and development of oil products.

Kinematic viscosity (40 digging) auspicious nucleus, about 46 cover Chang.

The kinematic viscosity of Scarland No. 46 ashless anti-wear hydraulic fluid is:

No. 46 anti-wear hydraulic oil can withstand a temperature of 80.

Anti-wear hydraulic oil (HM hydraulic oil) is developed from the anti-rust and anti-oxidation hydraulic oil, it has alkaline high zinc, alkaline low zinc, neutral high zinc type and ash-free type and other series of products, they are all according to 40'cKinematic viscosity is divided into four grades.

On the one hand, the role of hydraulic oil is to realize the energy transfer, conversion and control of the working medium, on the other hand, it also plays the role of lubrication, rust prevention, cooling, shock absorption and so on.

HL hydraulic fluids are made from neutral base oils with a high refining depth, plus antioxidant and anti-rust additives. HL hydraulic oil can be divided into six grades: E69DA5E887AA62616964757A686964616F according to the kinematic viscosity of 40.

HL hydraulic oil is mainly used for the lubrication of bearing boxes, low-pressure circulation systems or similar mechanical equipment circulation systems of various machine tools with no special requirements for lubricating oil and ambient temperature above O. It can be used for more than twice as long as mechanical oil. The product has good rubber sealing adaptability, and its maximum service temperature is 80.

2.Anti-wear hydraulic oil (HM hydraulic oil) is developed from the anti-rust and anti-oxidation hydraulic oil, it has alkaline high zinc, alkaline low zinc, neutral high zinc type and ash-free type and other series of products, they are all according to 40'cKinematic viscosity is divided into four grades.

Suitable for: l) Anti-wear hydraulic oil is mainly used for heavy-duty, medium-pressure, high-pressure vane pumps, piston pumps and gear pumps of hydraulic systems J mesh YB-D25 vane pumps, PF15 piston pumps, CBN-E306 gear pumps, YB-E80 40 duplex pumps and other hydraulic systems.

2) Hydraulic systems for medium-pressure and high-pressure construction machinery, imported equipment and vehicles. Such as the hydraulic system of computer numerical control machine tools, tunnel boring machines, crawler cranes, hydraulic backhoe excavators and shearers.

3) In addition to the medium and high pressure hydraulic system suitable for various hydraulic pumps, it can also be used for the lubrication of medium-load industrial gears (except worm gears and hyperbolic gears). The ambient temperature of its application is -10 40. The product has good adaptability to nitrile rubber.

HR hydraulic oil is the hydraulic oil used in low and medium pressure hydraulic systems with large changes in ambient temperature. The oil has good anti-rust and anti-oxidation properties, and on this basis, a viscosity index improver is added to make the oil have good viscosity and temperature characteristics. Due to the small amount of this kind of oil, it has not been vigorously developed.

Viscous temperature properties of the body.

The viscosity temperature characteristic is expressed by the viscosity index, which is the relative comparison value of the viscosity temperature characteristics of the oil.

Viscosity index The viscosity of lubricating oil decreases with the increase of temperature and increases with the decrease of temperature, which is the viscosity temperature characteristic of lubricating oil. Therefore, the report on viscosity must indicate the temperature at the time of the determination.

The viscosity index (VI) is generally used to evaluate the viscosity and temperature characteristics of oils, which is also an important quality index of lubricating oils.

Viscosity index (VI) = (L-U) (L-H) 100

l- The kinematic viscosity of petroleum products with the viscosity index is the same at 100, while the kinematic viscosity of petroleum products with zero viscosity index is 40, mm2 s;

u-The kinematic viscosity of the petroleum product at 100 for which the viscosity index is calculated, mm2 s;

h- The kinematic viscosity of petroleum products with the viscosity index is the same at 100, while the kinematic viscosity of petroleum products with viscosity index of 100 is at 40, mm2 s;

If you want to calculate the viscosity index of lubricating oil, you must first know the viscosity index of the base oil, which is blended with several base oils.

Viscosity of 100 degrees, viscosity of 40 degrees of 68, ask what the viscosity index is.

The viscosity bids are as follows:

1. The kinematic viscosity of industrial oil is 40 degrees, and the automotive oil is 100 degrees.

2. Dynamic viscosity: the internal friction generated when two layers of fluids with an area of 1 and a distance of 1m are in relative motion at a speed of 1m s. Unit:

n·s (Newton-seconds per meter) is also the coefficient of internal friction that characterizes the viscosity of a liquid, and is denoted by .

The viscosity of common liquids decreases with increasing temperature, and the viscosity of common gases increases with increasing temperature.

Conventional hydraulic fluids, such as No. 15, No. 32, No. 46, No. 68, are measured at 40 hours for kinematic viscosity.

Kinematic viscosity. It is the dynamic viscosity of the oil.

Ratio to the density of oil at the same temperature:

The CST said.

Specifically, it is to determine the time "seconds" required for a certain amount of sample to flow through the capillary tube of the kinematic viscosity nuclear meter at a specified temperature (such as 40 and 50), and then multiply it by the calibration constant of the viscometer to obtain the viscosity CST of the broad land sample

That is to say, when 32 hydraulic oil is 40, the kinematic viscosity is 32·· Changed from gold to rock runna.

En's viscosity = (153s 500c) * 200c 51s kinematic viscosity = (En's viscosity Enxun leakage mu) * 10 to the negative sixth power.

Dynamic viscosity = kinematic viscosity * density.
