Problems solved by technology

The oil temperature of flame-retardant hydraulic oil is high during use, and the temperature drops slowly. After the oil temperature increases, the performance of the seals will be greatly reduced. Especially in high-temperature environments, the oil leakage of the oil cylinder is serious, which increases the cost and seriously affects the use of hydraulic cylinder seals. life

preparation example Construction

[0018] The preparation method of the above-mentioned hydraulic oil is that the water glycol N46 and the SP846 fire-resistant hydraulic oil are uniformly mixed in a weight ratio of 100:3-7 to obtain the hydraulic oil of the present invention.

[0019] Wherein, the preferred weight ratio of water glycol N46 and SP846 fire-resistant hydraulic oil in the above-mentioned preparation method of hydraulic oil is 100:5.

Embodiment 1

[0021] Embodiment 1, preparation hydraulic oil of the present invention

[0022] Mix the aforementioned water glycol N46 and SP846 fire-resistant hydraulic oil in a weight ratio of 100:5, and put them into a 180L barrel for later use. The water glycol with the model number N46 was produced by Rongcheng Industrial Co., Ltd. of Panzhihua Steel City Group. Production date: January 2010. The fire-resistant hydraulic oil of model SP846 was produced by Rongcheng Industrial Co., Ltd. of Panzhihua Steel City Group. Production date: January 2010. The specifications of the raw materials are shown in Table 1.

Embodiment 2

[0026] Embodiment two, using the hydraulic oil of the present invention as the hydraulic system oil

[0027] Between February and July 2010, the applicant worked on a set of hydraulic system (steelmaking electric furnace hydraulic system, the hydraulic oil equipment for this system mainly includes: 3 sets of hydraulic oil pumps; 25 sets of hydraulic valves; 12 sets of hydraulic oil cylinders ) The hydraulic oil prepared in Example 1 is used as the oil for the hydraulic system. The oil pump and hydraulic valve were not damaged within 6 months of using the oil, and the hydraulic system was cleaned and maintained 3 times on a regular basis. A total of 40 barrels of oil were used (180L per barrel). The cost of this hydraulic system was about 130,000 yuan during this time. The results show that the hydraulic oil has little damage to hydraulic system equipment, and has good anti-wear, lubricating, anti-rust, anti-corrosion and other functions.

Abstract

The invention discloses hydraulic oil and a preparation method thereof, belonging to the field of metallurgy. The invention aims to solve the problems that the common hydraulic oil has large damage to an oil pump and a hydraulic valve and has high use cost. The hydraulic oil provided by the invention comprises water glycol and fire-resistant hydraulic oil, wherein the weight ratio of the water glycol to the fire-resistant hydraulic oil is 100:(3-7). The preparation method of the hydraulic oil comprises the step of uniformly mixing the water glycol and the fire-resistant hydraulic oil in the weight ratio of 100: (3-7). The hydraulic oil has small damage to the oil pump and the hydraulic valve, has the functions of wear resistance, lubrication, rust protection, corrosion prevention and the like, can effectively prolong the service life of a hydraulic element and reduce the phenomenon of oil leakage of a hydraulic oil cylinder, is suitable for being used in high-temperature environments,and has the advantages of simple preparation method and wide application prospect.

Description

technical field [0001] The invention belongs to the field of chemical industry, and particularly designs a hydraulic oil and a preparation method thereof. Background technique [0002] The oil used in the hydraulic system is referred to as hydraulic oil, and hydraulic oil is a kind of lubricating oil. As the working medium in the hydraulic transmission system, hydraulic oil has the functions of lubricating, cooling and rust prevention. Hydraulic oil is usually made of highly refined petroleum lubricating oil base oil or synthetic lubricating oil by adding anti-wear and antioxidant and other petroleum product additives. It is widely used in machine tools, mining engineering machinery, steelmaking machinery, transportation machinery, aviation, Aerospace and other aspects play an important role in industrial and agricultural production. [0003] Because water glycol has excellent flame resistance, cold resistance, wear resistance, foam resistance, rust resistance and extremel...
