  Hydraulic Oil Selection Guide

  Selection Based on Hydraulic System Type

  • Open Hydraulic System: If your hydraulic system is an open system, the oil has more opportunities to contact with air and is prone to mixing with impurities and moisture. It is recommended to choose hydraulic oils with good anti – emulsification and antioxidant properties, such as Eunaquer – B2 and Eunaquer – B3 in our anti – wear hydraulic oil series. They can effectively resist the erosion of moisture and impurities, prevent the deterioration of the oil, extend the service life of the hydraulic oil, and ensure the stable operation of the hydraulic system.
  • Closed Hydraulic System: Closed hydraulic systems have higher requirements for the cleanliness of hydraulic oil. High – cleanliness and strong anti – wear hydraulic oils should be preferred, such as Eunaquer – S1 and Eunaquer – S2 in the synthetic hydraulic oil series. These products can maintain good performance during the internal circulation of the system, reduce the generation of wear particles, reduce the risk of system failure, and ensure the high – precision operation of the equipment.

  Consideration of Working Pressure Factors

  • Low – Pressure Hydraulic System (Working Pressure Less Than 7MPa): For low – pressure hydraulic systems, generally, hydraulic oils with lower viscosity can be selected, such as Eunaquer – H1 Hosiery Spindle Oil (ISO Viscosity Grade 32) or Eunaquer – SP1 Spindle Oil (ISO Viscosity Grade 5). The lower viscosity helps the oil to flow quickly in a low – pressure environment, reduces energy loss, ensures the timeliness and accuracy of system response, and makes the equipment operate more smoothly and efficiently.
  • Medium – Pressure Hydraulic System (Working Pressure 7 – 14MPa): Medium – pressure hydraulic systems can use hydraulic oils with medium viscosity, such as Eunaquer2 Anti – wear Hydraulic Oil (ISO Viscosity Grade 46). Its moderate viscosity can meet the lubrication needs of the equipment while maintaining stable pressure transmission, ensuring the reliable operation of the system under medium – pressure working conditions and effectively preventing various problems caused by the oil being too thin or too thick.
  • High – Pressure Hydraulic System (Working Pressure Greater Than 14MPa): High – pressure hydraulic systems require high – viscosity and excellent anti – wear hydraulic oils, such as Eunaquer3 Anti – wear Hydraulic Oil (ISO Viscosity Grade 68) or Eunaquer – B3 Anti – wear Hydraulic Oil (ISO Viscosity Grade 68). Such hydraulic oils have strong load – carrying capacities, can withstand the huge pressure in a high – pressure environment, avoid the rupture of the oil film and the direct contact and wear of metal parts, provide reliable lubrication and protection for the system, and ensure the long – term stable operation of the high – pressure hydraulic system.

  Consideration in Combination with Working Temperature Range

  • Low – Temperature Environment (Working Temperature Below -15°C): For hydraulic systems working in a low – temperature environment, hydraulic oils with good low – temperature fluidity should be 优先 selected, such as Eunaquer – V1 High VI Hydraulic Oil (ISO Viscosity Grade 32), whose pour point is as low as -36°C. Hydraulic oils with good low – temperature fluidity can quickly start the equipment in cold conditions, reduce wear and energy consumption during startup, enable the hydraulic system to operate normally in a low – temperature environment, and avoid equipment failures caused by the solidification or excessive viscosity of the oil.
  • Normal – Temperature Environment (Working Temperature -15°C – 50°C): For hydraulic systems working in a normal – temperature environment, most conventional hydraulic oils can be used, such as Eunaquer2 Anti – wear Hydraulic Oil (ISO Viscosity Grade 46). These hydraulic oils can maintain stable performance at normal temperatures, provide reliable lubrication, sealing, and power transmission for hydraulic systems, and meet the needs of general industrial production.
  • High – Temperature Environment (Working Temperature Above 50°C): High – temperature environments have extremely high requirements for the thermal stability of hydraulic oils. Synthetic hydraulic oil series are recommended, such as Eunaquer – S2 Synthetic Hydraulic Oil (ISO Viscosity Grade 46). Such hydraulic oils have excellent thermal stability, can maintain low evaporation loss and good antioxidant performance at high temperatures, effectively prevent the deterioration of the oil and the formation of carbon deposits, ensure the continuous and stable operation of the hydraulic system under high – temperature working conditions, and extend the maintenance cycle and service life of the equipment.

  Adaptation Based on Equipment Material

  • Equipment Containing Copper Alloy Components: When the hydraulic system contains copper alloy components, zinc – free hydraulic oil must be used, such as Eunaquer – Z1 Zinc – free Hydraulic Oil (ISO Viscosity Grade 32). Some additives in ordinary hydraulic oils may react chemically with copper alloy components, leading to corrosion and damage of the components. Zinc – free hydraulic oils are specially formulated to effectively avoid this situation and protect the integrity and performance of the equipment.
  • Equipment with Requirements for Rubber Compatibility: If there are many rubber components such as seals or hoses in the hydraulic system, the compatibility between the hydraulic oil and rubber needs to be considered. For example, Water – glycol Fire Resistant Hydraulic Oil (Eunaquer – F) has good compatibility with most rubbers. Using a hydraulic oil with good compatibility can prevent rubber components from swelling, hardening, or aging, ensure the sealing of the hydraulic system, avoid leakage and other problems, and ensure the normal operation of the equipment.

  Key Points for Hydraulic Oil Use and Maintenance

  Usage Points

  • Storage: Hydraulic oil should be stored in a dry, cool, and well – ventilated place, away from direct sunlight and high – temperature environments to prevent the oxidation and deterioration of the oil. The storage container should be well – sealed to prevent the entry of dust, moisture, and impurities. Different brands, models, and batches of hydraulic oils should be stored separately to avoid confusion.
  • Filling: Before filling the hydraulic oil, it is essential to ensure that the filling tools and the hydraulic system of the equipment are clean to prevent impurities from entering the system. The filling amount and oil level should be strictly in accordance with the requirements of the equipment Manufacturer. Excessive or insufficient hydraulic oil will affect the normal operation of the equipment. The filling process should be carried out slowly to avoid the generation of foam, because foam will reduce the lubrication performance and transmission efficiency of the hydraulic oil and may even lead to system failure.

  Maintenance Points

  • Regular Inspection of Oil Quality: Hydraulic oil samples should be regularly taken for testing. The test items include viscosity, acid value, flash point, water content, impurity content, etc. Generally, a test should be carried out every 6 months of operation according to the usage frequency and working environment of the equipment. If it is found that the oil quality indicators exceed the specified range, such as a viscosity change of more than ±10%, an increase in acid value, or a water content exceeding 0.1%, measures should be taken in a timely manner, such as replacing the hydraulic oil or performing oil purification treatment.
  • Replacement of Filters: The function of the hydraulic oil filter is to filter impurities in the oil and keep the oil clean. Generally, the filter should be replaced every 24 months according to the severity of the working environment and the operating time of the equipment. In harsh environments such as dusty, humid, or high – temperature, the replacement cycle of the filter should be appropriately shortened. Regularly check the blockage of the filter. If it is found that the pressure difference of the filter is too large or the filter element changes color or deforms, it should be replaced immediately.
  • Prevention of Contamination: During the use and maintenance of the hydraulic system, special attention should be paid to preventing contamination. Keep the working environment clean to avoid the entry of dust, sand, and other impurities into the system. Regularly check the seals of the hydraulic system. If they are damaged or aged, they should be replaced in a timely manner to prevent external contaminants from entering the system. When adding hydraulic oil or performing equipment maintenance, clean tools and containers should be used to avoid bringing impurities into the system.

  Actual Application Case

  The hydraulic system of the rolling production line in a large steel enterprise previously used ordinary hydraulic oil. Under the high – temperature, high – pressure, and high – load working conditions, problems such as oxidation and deterioration of the oil, a decrease in viscosity, and insufficient anti – wear performance frequently occurred. This led to severe wear of key components such as hydraulic pumps and control valves, high equipment failure rates, huge maintenance costs, frequent shutdowns of the production line, and a serious impact on production efficiency. Later, after switching to our Eunaquer – S3 Synthetic Hydraulic Oil, due to its excellent high – temperature stability, high viscosity index, and outstanding anti – wear performance, the oxidation rate of the hydraulic oil in a high – temperature environment was significantly reduced, the viscosity remained stable, and the wear of components was effectively reduced. The maintenance cost was reduced by 25%, the shutdown time of the production line was significantly reduced, and the production efficiency was increased by 15%, bringing significant economic benefits and an improvement in production stability to the enterprise.
