Can hydraulic fluid be used as lubricating oil?

In daily application, many old equipment in the instruction materials, it is written that the use of oil lubrication, the old equipment marked with oil is actually not the current conventional use of internal combustion engine oil, but mechanical oil, most of these old equipment lubrication has been hydraulic oil.

Instead, some factories will use internal combustion engine oil lubrication.

Internal combustion engine oil is produced according to the requirements of the engine engineer and is specially used in gasoline engines.

and lubricating oil for diesel engines, which require a variety of performance such as high cleaning and dispersion, and the oil contains several functional additives such as cleaning and dispersion.

Hydraulic oil is mainly used in various hydraulic oil systems, and its viscosity grade is based on the hydraulic system.

The additives used are anti-oxidation, anti-rust, anti-wear and other additives, which are completely different from internal combustion engine oils. In general, hydraulic fluids cannot be used as internal combustion engine oils due to their lack of clean dispersibility. However, in order to simplify the variety of oil used on site, internal combustion engine oil (viscosity suitable) is also used as hydraulic oil in individual cases.

However, its performance indicators such as demulsification, hydrolysis stability, etc. cannot meet the requirements of hydraulic oil specifications. Therefore, in underground, water, and humid environments, internal combustion engine oil must not be used as a substitute for hydraulic oil.

Hydraulic fluids. It can be used as lubricating oil.

Hydraulic oil is a hydraulic system that uses the pressure energy of liquid.

The hydraulic medium used plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling and so on in the hydraulic system. 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. There are many types of hydraulic fluids and different classification methods, and for a long time, it has been customary to classify them by use, but also 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.

OK. First of all, hydraulic oil itself is a type of lubricating oil. In different mechanical components and the selection of different types of lubricating oil, according to its lubrication requirements to determine, if there is no lubricating oil and the mechanical friction is not very large, it can be temporarily replaced by hydraulic oil.

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.

Not exactly. Hydraulic oil works in a hydraulic system, although it also lubricates the system. But now that technology is so developed, the additives of hydraulic oil and engine oil are different, it is best for you to see what kind of lubrication you need?

If it's a swipe, you can.

Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy, which plays the role of energy transmission, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system. It itself is lubricating, depending on what the landlord wants to do with the lubricant? In the case of automobiles, the lubricating oil used for each mechanical component may be different, there is a special type of oil, each oil has its own composition, and the indiscriminate use may cause damage to the machinery or fail to achieve the expected effect.

Summary. Of course not. Hydraulic oil and lubricating oil are different and cannot be used as lubricating oil, there are similarities and differences between them. What are the dangers of hydraulic oil as lubricating oil?

Can hydraulic oil and lubricating oil be mixed?

Of course not. Hydraulic oil and lubricating oil are different and cannot be used as lubricating oil, there are similarities and differences between them. What are the dangers of hydraulic oil as lubricating oil?

Can hydraulic oil and lubricating oil work equally? Some customers ask: Can hydraulic oil and lubricating oil be used equally?

Zhongyang Lubrication Technology tells you: Of course not. Hydraulic oil and lubricating oil are different and cannot be used as lubricating oil, there are similarities and differences between them.

What are the dangers of hydraulic oil as lubricating oil? Let's make Zhongyang Lubrication Technology Department our home. Lubricating oil is a kind of lubricant, in various types of automobiles, mechanical equipment to reduce friction, protect machinery and parts of liquid or semi-solid lubricant, it is between two objects in relative motion, with the function of reducing friction caused by contact between two objects.

In addition, it also has lubrication, cooling, rust prevention, cleaning, sealing and cushioning. Lubricants are divided into diesel engine lubricants and gasoline engine lubricants, each of which is available in different grades. Hydraulic oil is the hydraulic medium used by the hydraulic system of liquid pressure, which plays a role in energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, sealing and so on in the hydraulic system.

Hydraulic oil is a kind of special oil that transmits and increases the strip pressure (dynamic), which is divided into ordinary hydraulic oil, anti-wear hydraulic oil and low condensation point hydraulic oil. Hydraulic oil for engineering machinery is a special oil for the hydraulic system developed according to the actual environmental requirements of engineering machinery and die-casting machines, and has better anti-wear, anti-rust, anti-emulsibility, anti-oxidation stability, destabilization and thermal stability than other hydraulic oils.

1.Lubricatability of hydraulic fluids.

Hydraulic oil is a special lubricating oil, which is mainly used in hydraulic systems to transmit power, transfer energy, control movement and other functions. Therefore, whether it can have both lubrication function is one of the important criteria for measuring hydraulic oil. Normally, the lubricating properties of hydraulic oil are the result of the combined action of its added extreme pressure agents, antioxidants, anti-wear agents and other components.

2.Precautions for hydraulic oil as lubricating oil.

Although hydraulic fluid has some lubricating properties, it does not mean that it can completely replace lubricating oil. When using hydraulic fluid instead of lubricating oil, the following points need to be noted. First of all, it is necessary to ensure that the base oil properties of the hydraulic oil match the lubricating oil required by the equipment.

Secondly, the type and amount of additives of hydraulic oil should be selected according to the operating environment and use conditions of the equipment. Finally, parameters such as viscosity of hydraulic oil should be adjusted according to the operating temperature and load conditions of the equipment to ensure the stability and reliability of lubrication performance.

3.Advantages of hydraulic oil as lubricating oil.

Compared with traditional lubricating oils, hydraulic fluids have the following advantages. First of all, the hydraulic oil has a high viscosity index and oxidation stability, and can maintain good lubrication performance at high temperature and high pressure. Secondly, the additives in hydraulic oil can effectively inhibit the corrosion and wear of metal surfaces and protect the normal operation of equipment.

In addition, the hydraulic fluid has good sealing properties, which can reduce leakage and contamination inside the equipment.

4.Hydraulic oil as a limiting condition for lubricating oil.

There are also certain limitations to the use of hydraulic oil as lubricating oil. First of all, due to the large number of additives added to the hydraulic oil, its base oil is gradually being replaced. Secondly, the advantages of hydraulic oil in terms of lubrication performance are mainly reflected in the hydraulic system, and in the high-speed, high-load mechanical transmission system, the lubricating performance of hydraulic oil often cannot meet the requirements.

In addition, there are also certain limitations in the adjustability and fluidity of liquid dust pressure oil.

In short, the application range of hydraulic oil as a lubricating oil is relatively limited, and it is only suitable for some equipment that requires the cooperation of hydraulic systems. At the same time, when using hydraulic oil instead of lubricating oil, the applicability and feasibility of hydraulic oil need to be carefully considered to ensure the normal operation and service life of the equipment.

What are the dangers of using hydraulic oil as lubricating oil?

1. The viscosity of hydraulic oil is generally relatively small, and the viscosity of lubricating oil is generally relatively large, so when hydraulic oil is used as lubricating oil, the formation of oil film is more difficult, and this is easy to lead to greater wear and tear of the machine, and even bring more serious consequences.

2. The main role of hydraulic oil and lubricating oil is different, therefore, the additives in them are also different, and the mixing of the two oils will lead to changes in the performance of the prudent, and even chemical reactions will occur to deteriorate the oil, which will lead to greater wear and tear of the machine.

3. The working temperature of the hydraulic system is not high, but the unit pressure transmitted by the hydraulic oil is very large. However, the high operating temperature of the engine crankcase, coupled with the infusion of high-temperature and high-pressure gas into the combustion chamber, will make the functions of the hydraulic oil fail faster, resulting in increased wear and tear on the machine, and in severe cases, greater losses.

Although hydraulic oil and lubricating oil have something in common, that is, anti-wear, cooling, anti-rust, cleaning, sealing, etc. But there are also many differences, and it is these differences that make hydraulic oil not available as lubricating oil. If there is a special indication that hydraulic oil can be used as lubricant, it is a different matter.

Therefore, remind friends in the industry that the hydraulic oil of the wide car cannot be used as lubricating oil.

However, hydraulic oil cannot be used as lubricating oil, there is a big difference between the two, and the two cannot be used interchangeably or mixed because of the same.

Hydraulic oil plays the role of lubrication, pressure transfer, cooling and corrosion protection, and its function and preservation should be placed in a clean container device to prevent contamination.

The role of hydraulic fluid:

1. Pressure transmission: The compressibility of the hydraulic oil is usually very small, so we can approximate that it is an incompressible fluid. So the hydraulic oil can transmit the pressure acting on it in all directions at its original size, thus lifting the hydraulic pressure of the equipment to prepare the intended action.

This is the pressure transfer function of the hydraulic oil.

2. Lubrication: In the dispersion of the hydraulic transmission system, after the friction coupling surface that forms relative motion is separated by the hydraulic oil film with a certain strength, the oil film can bear the load, so it can reduce the friction coefficient and reduce the wear of parts.

3. Cooling: The hydraulic oil has good thermal conductivity, which can take away the friction heat generated on the surface of the friction coupling in time, and wash the wear and debris and other dirt generated on the surface of the friction coupling in time, so as to reduce the temperature and reduce the wear effect on the surface of the friction coupling.

4. Anti-corrosion: At present, the main components of the hydraulic transmission system are metal parts, especially ferrous metal parts. If exposed to the atmosphere for a long time, they will be eroded and rusted due to the contact of water and air with harmful substances such as celery, which seriously endangers their performance. <>
