Cleaning a press hydraulic system is a meticulous and important process that requires certain steps and precautions to be followed. The following are detailed steps on how to clean the hydraulic system of the bending machine:

First, the preparation stage

Make sure the machine is shut down and disconnected from the power supply to ensure safety.

Prepare necessary cleaning tools and materials, such as cleaning cloths, cleaners (for hydraulic systems), oil drums, etc.

Second, the cleaning process

Clean the tank:

Open the tank cap and inspect and clean the inside of the tank for impurities and sediment.

Use a special tank cleaner or solvent such as kerosene and diesel to clean and ensure that the inside of the tank is clean and free of dirt.

Cleaning hydraulic lines:

Remove the hydraulic pipe, soak and clean it with detergent or solvent to remove the oil and impurities inside the pipe.

Use high pressure air or clean water to flush the inside of the pipe to ensure that there is no residue.

Clean hydraulic pumps and motors:

Remove hydraulic pump and motor, wipe housing and connection with cleaner.

Inspect and clean the inside of the pump and motor for dirt and wear.

Replace hydraulic oil and filter:

Drain the old hydraulic oil, and replace the new hydraulic oil to ensure that the oil is clean.

Replace or thoroughly clean the filter to remove oil and impurities.

Check and clean hydraulic valves and seals:

Check the working condition of the hydraulic valve, and clean the dirt on the valve body and valve core.

Check seals for wear and replace them if necessary.

Third, the work after completion

Reassemble the hydraulic system to ensure that the components are tightly connected without leakage.

Add new hydraulic oil to specified oil level.

Start the machine for trial operation to check whether the working state of the hydraulic system is normal.

Fourth, precautions

During the cleaning process, harsh cleaners or solvents should be avoided to avoid damaging the seals and components of the hydraulic system.

After the cleaning is completed, check whether the various components of the hydraulic system are installed correctly to ensure that there are no leaks and failures.

Regular cleaning and maintenance of the hydraulic system to extend the service life of the machine and maintain stable performance.
