What is the effect of mixing 68 anti wear hydraulic oil and 46 anti wear hydraulic oil?

Because different types of lubricating oil have their own particularities or differences in performance. Therefore, it is required to choose lubricating oil correctly and reasonably, avoid mixing, and do not allow random substitution. The following principles should be followed for the substitution of lubricating oil:

Try to use the same type of oil or oil with similar performance.

The viscosity should be comparable, and the viscosity of the substitute oil should not exceed 15% of the original oil, and the oil with slightly higher viscosity should be given priority for substitution.

The quality is replaced by the high.

Attention should also be paid to the environment and operating temperature of the equipment when choosing alternative oils.

Different types of grades, different manufacturers, and new and old oils should be avoided as much as possible. Mixing of the following oils is absolutely prohibited.

Military special oil and special oil cannot be mixed with other oil products.

Oils with anti-demulsibility requirements should not be mixed with oils without anti-demulsibility requirements.

Ammonia-resistant turbine oil should not be mixed with other turbine oils.

Zinc-containing anti-wear hydraulic fluids should not be mixed with anti-silver hydraulic fluids.

Gear oil should not be mixed with worm gear oil.

The following situations can be mixed:

The same manufacturer has the same different brand of products.

Different types of oils, if you know that the two components of the mixture do not contain additives.

Provided by Beijing Runshi.

The two grades are distinguished by the different viscosity of 40, and the other indicators are basically the same. In principle, oil products from different brands of manufacturers cannot be mixed, but in fact, we have done many oil mixing tests, in fact, they are all possible.

Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize the pressure energy of liquidsIt plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system. Due to the different application scenarios, the viscosity of the required hydraulic oil is also different, which also gives birth to many different types of hydraulic oil, the common ones are 46 hydraulic oil and 68 hydraulic oil.

Quality requirements: 1) Suitable viscosity and good viscosity and temperature performance to ensure that the hydraulic components are well lubricated, cooled and sealed under the conditions of changing working pressure and working temperature.

2) Good extreme pressure wear resistance to ensure that the friction pair in the oil pump, hydraulic motor, control valve and oil cylinder can be properly lubricated under high pressure, high speed and harsh conditions, and reduce wear.

Answer: Hello, the difference between No. 46 hydraulic oil and No. 68 pressure oil is mainly different viscosity properties and different pour points, No. 46 is thinner than No. 68 viscosity, and No. 68 hydraulic oil viscosity is relatively high, generally speaking, if the viscosity is relatively high, the oil film formed is relatively thick, in the case of low temperature in winter, it is recommended to choose No. 46 hydraulic oil.

Question: I used to use the number 68, but now I use the number 46, is it okay?

If you're from the north, it's just right to change to number 46 now.

Ask the South. Answer: Well, the weather in the south is still relatively hot, 46 and 68 will not affect your use, choose which one you can choose according to your actual needs, will not hurt the car.

Question: Now that the fuel tank is No. 68, can I almost add No. 46 to it?

Do not use different models and brands of hydraulic oil can not be mixed, in case the hydraulic oil has a chemical reaction, and its performance will change after the dark brown, milky white, odorous hydraulic oil is a deteriorated oil, so it can not be used.

Dear, it is highly recommended that you do not mix it up.

Isn't it okay to ask a question with one brand?

Question Okay, thank you.

No. 46 is a little thinner, and No. 68 is a little thicker.

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 divided into four grades according to the 40 C kinematic viscosity.

It can be widely used in industrial, shipping and mobile hydraulic and transmission systems, and is also suitable for the lubrication of gear drives, bearings and other industrial machinery with normal loads, which can be used in high-pressure piston pump systems.

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.

There are the following differences between No. 46 anti-wear hydraulic oil and No. 32 anti-wear hydraulic oil:

1. Viscosity. No. 32 anti-wear hydraulic oil: viscosity index of 98;

No. 46 anti-wear hydraulic oil: viscosity index of 101.

2. Pour point temperature.

No. 32 anti-wear hydraulic oil: pour point temperature is -18;

No. 46 anti-wear hydraulic oil: the pour point temperature is -12.

3. Anti-emulsibility time.

No. 32 anti-wear hydraulic oil: anti-demulsibility is 8min;

No. 46 anti-wear hydraulic oil: anti-emulsibility is 10min, 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 products, they are all according to 40'cKinematic viscosity is divided into four grades.

No. 46 is better, economical and durable, and No. 46 is different from No. 68 in stickiness and flash point. No. 46 is a little thinner, and No. 68 is a little thicker. Generally speaking, when the temperature is low in winter, use a 46 hydraulic belt with a lower viscosity to carry the oil, and when the temperature is high in summer, use a 68 hydraulic oil with a higher viscosity, and treat it especially in special circumstances.

There is also a difference between the two in the flash point, as we all know, the current hydraulic oil, also has its own flash point, so now No. 46 and No. 68 hydraulic oil, there will be a difference in the flash point, the flash point of No. 46 hydraulic oil is relatively low, so it is suitable for different industries, different environments to use, but both in anti-wear, as well as oxidation resistance are very good.

It is important to choose the appropriate viscosity, the viscosity of the hydraulic oil is too large, the energy loss of the hydraulic system is large, the system efficiency is low, and the oil pump is difficult to absorb oil; If the viscosity is too small, the amount of leakage in the pump is large, and the volume loss increases, which also reduces the efficiency of the system.

Comparatively speaking, No. 46 hydraulic oil is better, economical and durable, does not produce sludge for long-term use, and has the effect of keeping the hydraulic system highly clean. You can also choose according to your own needs.

How many kilograms is No. 46 anti-wear hydraulic oil 18 liters?

Hello Lu Qiqin No. 46 anti-abrasion liquid code early pressure oil kilogram is equal to 18 liters. The density of No. 46 anti-wear hydraulic oil is generally in liters, and its average value is taken in liters for the convenience of calculation. So kilogram = kilogram kilogram liter = 18 liters.

No. 46 anti-wear hydraulic oil from anti-rust and anti-oxidation hydraulic oil.

On the basis of development, it has alkaline high zinc, alkaline low zinc, neutral high zinc type and ash-free products, which are widely used in high-pressure hydraulic systems of industrial, shipping and mobile machinery and equipment.

It is also widely used in high-pressure hydraulic systems such as construction machinery, construction machinery, mining machinery, metallurgical equipment, etc.

1. Suitable viscosity and good viscosity temperature performance to ensure that the hydraulic components are well lubricated, cooled and sealed under the conditions of changing working pressure and working temperature.

2. Good extreme pressure anti-wear performance to ensure oil pump and hydraulic motor.

Control valves and cylinders.

The friction pair in the high pressure, high speed and harsh conditions get normal lubrication, reduce wear.

It is normal to be below 1000ppm, and in the hydraulic system, the water content of the closed beam for anti-wear hydraulic oil containing water should be controlled below, that is, below 1000ppm. Because when the moisture content of anti-wear hydraulic oil exceeds, it will lead to problems such as viscosity change, oxidation acceleration and corrosion, which will damage the normal operation of the hydraulic system. Therefore, if the 46 anti-wear hydraulic oil contains more than 1000 ppm of water, it is not normal and needs to be replaced in time or take corresponding treatment measures to ensure the normal operation of the hydraulic system.
