Precautions for replacing hydraulic oil
Choose the right hydraulic oil: Choose the right hydraulic oil model according to the requirements of the equipment and environmental conditions. The wrong hydraulic oil may cause the hydraulic system to degrade or be damaged.
Preparation: Before changing the hydraulic oil, you need to prepare the necessary tools such as hydraulic oil, filters, seals, open-end wrenches, oil drums suitable for the equipment, and ensure that the selected hydraulic oil model meets the equipment requirements.
Clean the working environment: The hydraulic oil should be replaced in a clean working environment to avoid dust and impurities from entering the hydraulic system. Use a clean cloth or paper towel to wipe the relevant parts to remove old oil and dirt.
Drain the old oil: Open the bottom drain plug or valve of the hydraulic oil tank to drain the old oil. Make sure to drain the old oil thoroughly and check the oil pan for metal particles or other impurities, which may be signs of wear.
Clean the hydraulic system: In some cases, it may be necessary to use a cleaning agent to clean the inside of the hydraulic system to remove sediment and dirt. After cleaning, drain the cleaning fluid again and replace with clean hydraulic oil.
Replace the hydraulic oil with good quality: You get what you pay for. We do not advocate that you buy expensive hydraulic oil, but choose relatively good quality hydraulic oil, which has a longer service life and is also a protection for the hydraulic system and the entire device.
Do a good job of exhausting the cylinder, etc.: After filling the hydraulic oil and connecting the pipe joints, the residual air in the hydraulic pump and hydraulic cylinder must be discharged again. If it is not discharged, the residual air may cause problems such as reduced pressure, vibration, noise and performance degradation.
Replace the hydraulic oil on the same day: The replacement and addition of the hydraulic oil in the cylinder needs to be continuous. The exhaust of the cylinder and the oil circuit is mentioned above. If the interval is too long, one may cause gas to enter the hydraulic system, or liquid and other media to penetrate, which will also cause rust to the metal parts of the system.
