In the hydraulic system, the hydraulic oil acts on the hydraulic system just like blood is to the human body, so its importance is not much to say. With the increasing application of hydraulic equipment and the progressive development of technology, the importance of hydraulic oil has also received more and more attention. Many institutions at home and abroad have continued to increase investment in the research and development of the latest generation of hydraulic oil and have achieved results - a new era of hydraulic oil is approaching. As we all know, hydraulic oil is one of the necessary components of almost any hydraulic system powered by a hydraulic pump. Through the accurate calculation of the fluid flow resistance (ie, viscosity), the proper viscosity of the hydraulic oil can provide the necessary protection for the hydraulic pump to ensure that the moving parts are in an effective lubrication state and their wear is minimized. However, providing the necessary lubrication protection is only the most basic requirement for hydraulic oil; what is more important is how to make the hydraulic oil perform its function under high load conditions or under changing operating conditions. For example, for the hydraulic equipment for outdoor operations, the ambient temperature of the hydraulic equipment varies greatly not only with the season, but also with the sudden change of day and night or the change of operating location. At high temperatures, the hydraulic oil becomes lean, resulting in insufficient lubrication and increased wear. At low temperatures, the hydraulic system is difficult to start and wear starts to increase. Improper hydraulic fluids not only cause wear problems, but also cause problems such as excessive corrosion, sludge deposits, cavitation, filter clogging, and stuck valves. If these equipment problems are not solved in time, not only the noise will increase, the work accuracy will decrease, but also the maintenance frequency will increase, the fault shutdown will occur, and eventually the equipment will be damaged prematurely, which will greatly increase the maintenance cost of the equipment and reduce the production efficiency of the equipment. . Therefore, choosing the right hydraulic oil can make hydraulic equipment users get more than expected return, although the importance of hydraulic oil is often overlooked. What customers need is a solution, not just a product Shell Lubricants is committed to providing users with a comprehensive solution for hydraulic oils. Many customers received help from Shell Lubricants when they encountered various problems with hydraulic equipment. When a customer encounters a hydraulic problem, Shell will send technical experts in the field to inspect and evaluate the current working environment of the customer, and then recommend the optimal technical solution for the hydraulic oil product according to the customer's demand, and at the same time, how to improve the customer's equipment Operational efficiency is an important part of a comprehensive solution. For example, the world-famous company KEC has more than 100 die stamping equipment in the semiconductor device manufacturing branch at Wuxi. The customer once found that two axial piston pumps in the production line were damaged, resulting in serious long-term downtime. Subsequently, they switched to Shell Tellus S2M68, which not only lasted longer but also protected the hydraulic system more reliably and stably. By using this product and adopting Shell's hydraulic equipment maintenance specifications, the oil change period was increased from 12 months to 2 years, and the maintenance cost and downtime were significantly reduced, which greatly improved the production efficiency and saved KEC directly. $32,824. For Shell Lubricants, hydraulic oil that fully protects equipment and helps customers improve energy efficiency under different conditions is a good hydraulic oil, and the corresponding hydraulic oil technology is also essential. Wide temperature hydraulic oil technology In addition to providing the most basic protection for hydraulic systems, hydraulic fluids are even more notable for how hydraulic fluids operate efficiently under extreme conditions and provide equal protection in different environments. Shell Lubricant's research in this area is very good. For example, the Tellus S4VX hydraulic oil has a viscosity index of 300, and can maintain a smooth flow at very low temperatures where conventional hydraulic fluid becomes very viscous and cannot support equipment operation, ensuring that the equipment can be kept at extremely low temperatures. The start-up requires no or only a simple heating system to increase the equipment reliability and operating efficiency of the hydraulic system, helping the user to increase productivity. The product has been widely used in the hydraulic system of wind turbines and other equipment in extremely harsh environments and has been highly recognized by customers. In the outdoors, the temperature will change daily and seasonally, or the device will change from one place to another. In the case of relatively high temperatures, many hydraulic oils will become thinner during operation and lose their resistance, thus reducing the protection of the equipment.
