How to use hydraulic oil correctly

The correct use of hydraulic oil is crucial to the stability and life of hydraulic press equipment. The following are the key steps and precautions in the use of hydraulic oil compiled by experts from Jianlong Hydraulic Technology, a Chinese intelligent professional hydraulic press manufacturer, for reference.

1. Choose the right hydraulic oil

1.1 Viscosity grade: Select hydraulic oil with appropriate viscosity according to the recommendations in the equipment manual. Viscosity that is too high or too low will affect the efficiency and response speed of the hydraulic system.

1.2 Operating temperature range: Ensure that the hydraulic oil can maintain stable performance within the operating temperature range of the equipment to avoid oil quality deterioration caused by high temperature or viscosity increase caused by low temperature.

1.3 Anti-wear performance: Select hydraulic oil with good anti-wear performance to reduce friction in the hydraulic system and extend the service life of the equipment.

2. Keep the hydraulic oil clean

2.1 Avoid contamination: Hydraulic oil is easily contaminated by external factors such as dust, moisture and metal particles during use. Contaminated hydraulic oil will accelerate the wear of the equipment and affect the normal operation of the hydraulic system.

2.2 Regular filtration: Install high-efficiency filters and check and replace them regularly to ensure the cleanliness of the hydraulic oil.

3. Regularly replace hydraulic oil

3.1 Follow the maintenance plan: According to the equipment manufacturer's recommendations, replace the hydraulic oil regularly, usually when the oil reaches its service life or the oil quality deteriorates significantly.

3.2 Check oil quality changes: Regularly check the color and viscosity changes of the hydraulic oil. If the oil is found to be black or has an odor, it should be replaced immediately.

4. Check the oil level

4.1 Maintain the appropriate amount of oil: The hydraulic system should operate within the specified liquid level range. Too low a liquid level will cause bubbles to enter the hydraulic system, causing cavitation and affecting system pressure and efficiency.

4.2 Check for oil leaks: Regularly check the sealing of the hydraulic system to prevent hydraulic oil leakage.

5. Pay attention to the effect of ambient temperature on hydraulic oil

In low temperature environments, hydraulic oil may become too viscous, affecting the start-up and operation of the hydraulic press; in high temperature environments, the fluidity of hydraulic oil may be too high, resulting in a decrease in lubrication effect.

6. Use the correct storage method

6.1 Storage environment: Hydraulic oil should be stored in a dry and cool place, avoiding direct sunlight and high temperature environments to prevent oil deterioration.

6.2 Prevent oil mixing: Hydraulic oils of different brands and types may have different additive components. Mixing may produce adverse chemical reactions and affect the performance of the oil.

By using hydraulic oil correctly, the service life of the hydraulic system can be extended, the efficient operation of the equipment can be ensured, and the failure rate and maintenance costs can be reduced.
