Hydraulic system is a system that uses liquid to transfer energy, while the hydraulic fluid is an important part of the hydraulic system, and its selection of the appropriate hydraulic fluid not only ensures the normal operation of the hydraulic system, but also extends the service life of the system. In this paper, we will introduce the selection of hydraulic fluid and precautions to help readers better understand the operating principle of the hydraulic system, so as to achieve optimal design.

  Selection of hydraulic fluid and precautions in the hydraulic system

  Hydraulic system through the liquid transfer of energy to realize the operation of mechanical equipment, and hydraulic oil is one of the key components of the hydraulic system. The selection of hydraulic fluid directly affects the normal operation and service life of the hydraulic system, so in the design of the hydraulic system, you need to carefully consider the selection of hydraulic fluid and precautions.

  First, the selection of hydraulic oil

  The basic properties of hydraulic fluid

  The basic properties of hydraulic oil refers to its viscosity, fluidity, oxidation resistance, anti-wear, anti-emulsification and so on. According to different working conditions and requirements, the need to choose different properties of hydraulic oil. For example, in the high-temperature environment of the hydraulic system, you need to choose a smaller viscosity of the hydraulic oil to ensure the normal operation of the system.

  Brand and quality of hydraulic fluid

  The brand and quality of hydraulic fluid is also very important. Generally speaking, it is recommended to choose the famous brand of hydraulic oil, and pay attention to its production date and shelf life. In addition, in order to ensure the quality of the hydraulic fluid, it is also necessary to carry out regular testing and replacement of the hydraulic fluid.

  Additives in Hydraulic Fluid

  The additives of hydraulic oil can improve the performance of hydraulic oil, such as improving its oxidation resistance, anti-wear and so on. Therefore, when choosing hydraulic oil, you need to pay attention to the type and content of its additives to meet different working conditions and requirements.

  Second, precautions

  Avoid mixing different brands or models of hydraulic fluid

  Different brands or models of hydraulic oil may contain different additives and components, if mixed will lead to unstable performance of the hydraulic oil, or even produce chemical reactions, thus affecting the normal operation of the hydraulic system.

  Pay attention to the service life of the hydraulic oil

  The service life of the hydraulic oil and its quality, operating temperature, working environment and so on. If the hydraulic oil is used for too long or contaminated, it will lead to a decline in its performance, thus affecting the normal operation of the hydraulic system. Therefore, when using hydraulic oil, you need to pay attention to its service life, and regularly replaced.

  Avoid contamination of hydraulic oil

  The hydraulic fluid in the hydraulic system is often contaminated by air, moisture, dust, etc., which affects its performance. Therefore, when using the hydraulic system, you need to pay attention to its sealing and cleanliness, and take appropriate measures, such as regular replacement of filter elements.

  Pay attention to the storage and transportation of hydraulic oil

  The storage and transportation of hydraulic oil also need attention. Hydraulic oil needs to be stored in a ventilated, dry, cool place, avoid direct sunlight and high temperature environment. In the transportation of hydraulic oil, need to pay attention to its sealing and stability, and avoid mixing with other substances or shock.

  Hydraulic oil is a very important part of the hydraulic system, its selection and use need to pay attention to a variety of factors. In the design of the hydraulic system, you need to carefully consider the selection of hydraulic fluid and precautions to ensure the normal operation and service life of the hydraulic system.
