Hydraulic oil selection and use skills
Hydraulic oil is an indispensable and important part of the hydraulic system, it plays the role of lubrication, sealing, cooling and transferring pressure. The correct selection and use of hydraulic fluids is essential for the proper functioning of the hydraulic system. When choosing a hydraulic fluid, there are a few key factors that should be considered.
1.Working conditions of hydraulic system: The working conditions of different hydraulic systems are different, so the selection of hydraulic oil should be based on the working pressure, temperature range, working environment and other factors of the system. For example, hydraulic fluids with high flash points and low volatility should be selected in high-temperature environments to ensure the safety and stability of the system.
2.Viscosity grade of hydraulic fluid: The viscosity of hydraulic fluid determines its fluidity and lubricating properties in the hydraulic system. In general, the viscosity grade of the hydraulic system should be determined according to the requirements of components such as hydraulic pumps, valves, and hydraulic cylinders. Too high or too low viscosity will affect the normal operation of the hydraulic system.
3.Oxidation stability of hydraulic oil: Oxidation and degradation of hydraulic oil during long-term use, which reduces the performance of the hydraulic system. Therefore, when choosing a hydraulic fluid, its oxidative stability should be considered. Hydraulic oil with good oxidation stability can maintain stable performance under high temperature and high pressure working conditions, and prolong the service life of the hydraulic system.
4.Filtration performance of hydraulic oil: Fluids in hydraulic systems are often affected by contaminants, such as particles, moisture, gases, etc. Therefore, it is essential to select a hydraulic oil with good filtration performance to protect the components of the hydraulic system and improve the reliability of the system.
When using hydraulic fluid, you also need to pay attention to the following tips.
1.Regularly check the quality of hydraulic fluid: Regularly check the quality of hydraulic fluid, including the color, odor, viscosity of the fluid, etc. If the oil is found to be abnormal, it should be replaced in time.
2.Keep your hydraulic fluid clean: The cleanliness of your hydraulic fluid is critical to the proper functioning of your hydraulic system. Therefore, when using hydraulic fluid, the working environment should be kept clean and avoid the entry of impurities and contaminants.
3.Control the temperature of the hydraulic oil: Too high a temperature of the hydraulic oil will reduce its viscosity and affect the performance of the hydraulic system. Therefore, when using the hydraulic system, the temperature of the hydraulic oil should be controlled to avoid overheating.
4.Change the hydraulic oil regularly: The hydraulic oil will gradually degrade and contaminate during long-term use, so the hydraulic oil should be changed regularly to maintain the normal operation of the hydraulic system.
To sum up, the correct selection and use of hydraulic fluid is essential for the proper functioning of the hydraulic system. By considering factors such as the working conditions of the hydraulic system, the viscosity grade of the hydraulic oil, the oxidation stability and the filtration performance, and following the tips for using the hydraulic oil, the performance stability and service life of the hydraulic system can be guaranteed.
