Information

Is hydraulic fluid lubricating oil or not? The question popped up, but it was a bit hard to answer. To understand the difference, let's first explain what lubricants are and what hydraulic fluids are.

Lubricating oil is a kind of lubricant, which is between two objects in relative motion and has the function of reducing friction caused by contact between two objects. In addition, it also has cooling, rust, cleaning, sealing and buffering and other functions. And lubricating oil is divided into diesel engine lubricating oil and gasoline engine lubricating oil, they have different grades to choose from.

Hydraulic oil is the hydraulic medium used in the hydraulic system using liquid pressure energy. It plays the roles of energy transfer, anti-wear, system lubrication, corrosion prevention, rust prevention, cooling, sealing and so on in the hydraulic system. Hydraulic oil is a kind of special oil to transfer pressure (power), it is divided into ordinary hydraulic oil, anti-wear hydraulic oil and low freezing point hydraulic oil and so on. The hydraulic oil of construction machinery is a special oil for hydraulic system developed according to the actual working environment requirements of construction machinery and die casting machine. Compared with other hydraulic oil, hydraulic oil of construction machinery has better anti-wear, anti-rust, anti-emulsification, anti-oxidation stability, hydrolysis stability and thermal stability.

Similarities and Differences between hydraulic oil and lubricating oil:

1. Similarities

From the above explanation, we can see that lubricating oil and hydraulic oil have the same anti-wear, cooling, rust, cleaning, sealing and so on. And that's one of the main reasons we hear a lot about hydraulic fluids being used as lubricants. Hydraulic lubricating pump

2. Differences

(1) The main function is different. In the main role, lubricating oil and hydraulic construction machinery oil or different. The main function of lubricating oil is to reduce the friction of the object caused by mechanical damage; The main function of hydraulic oil in construction machinery is to transfer pressure (power).

. Different concerns. It is because of their different main functions that lubricants pay more attention to reducing friction, slowing down wear and preventing metal sintering. Hydraulic oils, on the other hand, pay more attention to the viscosity index, which requires hydraulic oils to perform well at high temperatures and at low temperatures to ensure easy flow and reduce energy consumption.

Hazards 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 a lubricating oil, the formation of oil film is relatively difficult, and this will easily lead to relatively large machine wear, and even bring more serious consequences.

2, the main role of hydraulic oil and lubricating oil is different, therefore, they are also different additives, and the two oils mixed will lead to changes in performance, and even chemical reaction to make the oil deteriorated, leading to greater machine wear.

3, the working temperature of the hydraulic system is not high, but the unit pressure transferred by the hydraulic oil is very large. However, the working temperature of engine crankcase is very high, coupled with the surge of high temperature and high pressure gas in the combustion chamber, which will make various functions of hydraulic oil fail faster, thus leading to increased wear and even greater loss.
