How To Ensure The Optimal Performance Of Hydraulic Jack
Precautions for replacing hydraulic oil
Over time, the quality of hydraulic oil in a jack can deteriorate due to environmental factors and temperature changes.
Therefore, replacing the hydraulic oil is crucial for maintaining the jack's performance over the long term.
Unfortunately, many people are unsure about the proper procedure for replacing hydraulic oil,
leading to a significant decline in the jack's performance.
In general, the hydraulic jack has an oil filling port located on its side.
To begin, locate the rubber plug of the oil filling port and remove it.
Then, position the hydraulic jack upright so that the filling port is facing upward.
Slowly pour the hydraulic oil into the filling port until it is filled.
Afterward, push the piston rod tightly and reinsert the rubber plug, ensuring it is tightly secured.
Here are a few important details to consider during the oil replacement process:
First: Prior to adding new oil, clean out the old oil residue from the jack.
Second: To prevent spillage, you can use a funnel while pouring the oil.
Third: Consider adding a layer of filter screen when pouring the oil.
This will help filter out tiny impurities present in the hydraulic oil, resulting in higher oil purity.
Fourth: Avoid overfilling the hydraulic oil. In general, the oil level should be equal to the horizontal position of the oil port.
By following these steps and paying attention to these details, you can successfully
replace the hydraulic oil in your hydraulic jack, ensuring its optimal performance.
Precautions when using hydraulic jacks
1. When multiple hydraulic tools are used simultaneously, designate a person to provide commands
to ensure synchronous lifting or lowering. Place wooden blocks between adjacent
hydraulic jacks to maintain proper spacing and prevent sliding.
2. The hydraulic tool should be stable during lifting operations.
Lift the heavy object slightly and check for any abnormalities.
Proceed with lifting only if there are no issues.
Avoid extending the handle excessively or applying excessive force.
3. Do not overload the hydraulic tool or exceed the height limit.
If a red line appears on the sleeve, it indicates that the rated
height has been reached, and the lifting operation should be stopped.
4. Regularly inspect the sealing and pipe joints of the hydraulic tool, ensuring that they are safe and reliable.
5. Avoid using the hydraulic tool in environments with acid, alkali, or corrosive gases.
6. Ensure that the hydraulic tool is placed on a flat and sturdy surface.
Use oil-free planks to expand the bearing surface and ensure safety.
Avoid using iron plates to prevent sliding.
Emergency Hydraulic Jack Maintenance Procedures
1. Check for Visible Damage
Inspect the hydraulic jack for any visible signs of damage, such as cracks, leaks, or bent components.
If any damage is found, do not use the jack and seek professional assistance.
2. Secure the Area
Ensure that the area where the hydraulic jack will be used is clear of any obstacles or hazards.
This will prevent accidents and provide a safe working environment.
3. Check Hydraulic Fluid Level
Verify the hydraulic fluid level in the jack's reservoir.
If the fluid level is low, add the appropriate hydraulic fluid as recommended by the manufacturer.Be cautious not to overfill.
4. Bleed Air from the System
If the hydraulic jack is not operating properly or there is air trapped in the system,
bleeding the air out may help restore functionality.
Refer to the manufacturer's instructions on how to properly bleed the Hydraulic System.
5. Lubricate Moving Parts
Apply lubrication to the moving parts of the hydraulic jack, such as the piston rod and hinges,
to ensure smooth operation. Use the recommended lubricant as specified by the manufacturer.
6. Test the Jack
Before using the hydraulic jack in an emergency situation, perform a test lift with a light
load to ensure that the jack is functioning correctly and can handle the intended load.
Observe the jack's stability and listen for any unusual noises.
