Hydraulic systems are widely used in mining, construction, manufacturing, transportation, forestry, and in a variety of industrial applications, etc.; Hydraulic fluids are the medium in which force is transmitted in hydraulic machines. The power loss of the hydraulic machine is mainly in the machine and the hydraulic system. The energy loss in hydraulic systems includes the following: (1) the loss due to sliding friction in the hydraulic pump and the motor and (2) the lack of pressure inside the pipes (3) the loss due to oil leakage inside the hydraulic pump, hydraulic motor and control valves. The hydraulic oil delivered from the hydraulic pump reaches Through the control valve to the actuators such as transmission motors, work equipment cylinders, etc. to carry out the work of Jie drilling, travel, swing 0 and so on.

The temperature of the hydraulic oil in a variety of hydraulic machines varies from 50 to 70°C during normal operation, though it reaches about 50 to 80°C in off-highway hydraulic equipment and may sometimes rise from 80 to 100°C in summer. in the tropics; The internal leakage of the hydraulic component is lower for the new oil with higher viscosity compared to the conventional oil and in the operating temperature range; Sliding friction resistance increases in the hydraulic pump and hydraulic motor and pressure loss inside the pipes increases, and as a result (SUN) the efficiency of the hydraulic pump decreases. From Lali, the new oil is characterized by a lower viscosity compared to the special viscosity of conventional hydraulic oil in a low temperature range for operation in cold regions. When a hydraulic system is operated in 0 cold zone, its workability may be less than normal due to the low fluidity of the new hydraulic oil in the hydraulic system.Therefore, it may provide good fluidity and obtain good workability, and this feature will result in a decrease in pump efficiency.

5 on a higher overall efficiency of the hydraulic system in a wide range of temperatures. In order to enhance the efficiency of the pump; A fluid with a higher ISO viscosity can traditionally be used at a higher operating temperature, but care must be taken regarding the efficiency of the temperature fluid during cold starting. That all hydraulic coils should protect components from excessive wear and maintenance costs even under 0 levels of excessive temperature. Lay may deteriorate due to a variety of factors. Taal is a common problem that can create serious problems in machines, transmissions and hydraulic systems. It is commonly blamed on the presence of excessive water vapor in the system. Oxidation and foaming are other problems that form over time and affect the performance of hydraulic systems. to achieve perfect operation; Any hydraulic fluid must be partially incompressible and flow easily. Furthermore, the fluid must provide adequate lubrication of the moving parts and stability under foreseeable conditions of use and is compatible with the materials used to construct the hydraulic system; The fluids must have the ability to protect the components of the system from the chemical effect with Al materials that can Jax the system.

The hydraulic shaft acts as the power transmission medium in any hydraulic system. The most commonly used fluids are petroleum oils, synthetic lubricants, oil-water emulsion, and water-glycol mixtures. The basic requirements for a hydraulic fluid are that it has a suitable high viscosity index, wear protection, good oxidation stability, suitable spill point, good emulsification, rust inhibitor, foaming resistance and sealant compatibility. Anti-wear oils are typically used in compact, high-pressure, high-capacity pumps that require superior lubrication protection. Certain synthetic lubricants and water-based fluids are used as fire retardant coatings. Synthetic lubricants are also used in extreme temperature conditions. Typically, the initial viscosity of the bit is selected based on considerations other than energy efficiency, flow rate, temperature range, and internal leaks; Etc. The energy losses are determined by cull's initial viscosity, temperature, pressure and its shear rate. It is usual that conventional hydraulic fluids for hydraulic systems inside factories contain OY viscosity index improvers. These fluids are generally used at temperatures below zero. It has been observed that there is a shear-thinning effect attributed to the [sale] temporary alignment of a polymeric viscosity index improver (7) for multigrade 5 motor oils to give a fuel economy advantage over monograde oils. Nevertheless; Index 7 may help to take advantage of the effect of shear thinning to reduce friction and save energy. There are a large number of synthetic fluids as well as mineral mixtures that can be used as base fluids for contemporary industrial oils, in particular hydraulic oils. The most common (Bad) 0 for butter with a conventional mineral base is the synthetic Wl poly-alpha-—olefins (PAO) and poly-glycols and esters. Unconventional oils are produced with a mineral base called “La hydrogenated base oil” from petroleum with a “very high las viscosity index” (VHVI) either by excessive hydrocracking techniques or by ISO dewaxing. The hydrocracking process results in base stocks containing more paraffin and less 5-aromatic hydrocarbons, while PAO consists mostly of paraffin only. that this molecular structure

It has better heat of viscosity and better pressure plate behavior Lan respectively with higher viscosity index and lower compressive viscosity coefficient. The high pressure viscosity behavior of VHVI base stock types is substantially lower than that of the solvent-refined base stock types. Therefore, hydrocracked oils and PAO oils show a significant advantage over solvent-refined base oils in reducing friction under EHD lubrication systems. Compressibility is vitally important for hydraulic fluids and one of its main functions is power transmission. Accurate power transmission in high-pressure hydraulic systems requires fluid viscosity (as well as volume) to be accurate and must be the least pressure-sensitive or have the lowest pressure-viscosity coefficient. Low viscosity at high pressure is also useful for reducing the losses in viscosity-related churning ability under loading conditions. The viscosity, temperature, and viscosity-temperature properties of liquid hydrocrionies depend to a large extent on their molecular structure. According to the existing theories of liquid composition; The greater the degree of freedom in the molecular structure of the liquid, the higher the compressibility. Various types of viscosity index improvers are available in the market for the preparation of industrial fluids including 5 hydraulic fluids which can be olefin copolymer (OCP) or styrene butadiene copolymer (SBR) or styrene copolymer (SIP) or polymethacrylate (PMA) or maleic anhydride styrene co-polymer or “poly isobutylene (PIB) or dispersive polymethacrylate (DVM) or viscosity modifier (AVM) 516110 etc. The most commonly used improvers of the Vils category are polymethacrylates and copolymers of 0 olefin. The poly methacrylates have more stable properties than the CuA viscosity copolymer of olefins. The shear thinning effect should be more pronounced for polymers with higher molecular weight and higher polymer concentration in the oil. The reflexive behavior reduces the effective viscosity of the lubricant under high shear operating conditions resulting in reduced viscosity resistance and improved fuel economy. simultaneously The behavior of the non-Newtonian oil causes a decrease in the thickness of the thin layer (EHD) to a defined value.

It is an effective high shear viscosity. So; The potential negative effect of oil thinning becomes beneficial to energy savings; Which made the effect reverse. Friction enhancers create boundary layers on rubbing metal surfaces, physical adsorption, and chemical interference with metallic surfaces. The structure of the boundary layer is different from the surface layer formed by sulfur, phosphorus or chlorine containing additives and anti-wear materials.

normal or super pressure. Normally these additives (additives) do not decrease or increase frictional force and energy consumption. Friction enhancers react chemically with metal surfaces and are considered effective for boundary systems 5 at high temperature. The friction reduction of the enhancers is based on the reaction

0 Thermally active chemical with metal surfaces and its effectiveness is higher at higher temperature levels. Long-chain, polar organic acids and esters function at lower temperatures and then provide thin anti-friction coatings on the metal's surfaces. The anti-friction efficiency of the friction enhancer depends on the composition and thickness of the surface layers formed on the surfaces of the metal. The losses in industrial equipment consist of friction faces in bearings, gear meshes and vanes ring

5 The piston liner, the friction faces in the joints, and the losses due to fluctuations in the seals, filters, valves, etc. In the previous field of producing hydraulic oils; in general; Mineral oils or mineral cul are used with synthetic fluids or ester complexes of fatty acids. That such context is in use for this cul base enhances performance.
