In hydraulic transmission, hydraulic oil is the working medium that transmits motion and power. It has been proved by practice that hydraulic system failures caused by hydraulic oil account for 75% of the entire hydraulic failure rate, so we must increase the degree of attention. For the newly-made hydraulic oil tank, we may concern how does the pollution cause? How can we effectively clean up?

Causes of Pollution: There are many reasons for the pollution of newly-made oil tanks.

1. The pollutants mixed from the external environment are mainly air, dust, cotton yarn, water droplets, etc.

2. The contaminants that remain incompletely cleaned include iron filings, burrs, welding slag, rust, cotton yarn, grit, cleaning fluid, etc.

3. The contaminants generated during the installation process mainly include unclean hydraulic accessories, wearing gloves during installation, and not re-checking before closing the cover.

Clean-up Measures:

1. The new hydraulic oil tank formed by welding shall be treated as follows before phosphating.

• Use a spatula to thoroughly remove the welding slag and weld nodules at the surrounding welds.
• Use a file to clean the burrs and burrs of the oil tank orifice and the connecting threaded orifices everywhere.
• Wipe all parts with a lint-free cloth and clean kerosene.
• Use compressed air to blow off the dust on the surface of the oil tank and the cleaned parts.
• If you need to install a gasket on the plane of the sealing cover, you must make the gasket in advance.

2. Clean the appearance of the oil tank after phosphating

• Use a spatula to clean the phosphating solution residues and particles on the inner surface of the oil tank.
• If there are rust spots, use the sand cloth to remove rust, and apply phosphating solution to the rust-removed parts, and clean the phosphating solution residue after 2 minutes.
• Clean kerosene with a lint-free cloth, clean the oil ports of the connecting threads everywhere and blow dry with compressed air, seal the oil port with a clean screw plug in time, and thoroughly scrub the inner surface of the tank with clean kerosene.
• Knead the dough with clean anti-wear hydraulic oil (L-HM46#), paste the welds, holes, corners and other parts of the surface one by one, and repeat the operation until the dough is free of impurities, fine dust and particles.
• Blow the inside of the oil tank thoroughly with compressed air, and apply clean L-HM46# anti-wear hydraulic oil (to prevent the inside of the oil tank from rusting).
• If the cleaned oil tank is not assembled for the time being, it should be covered immediately, and it can be sealed with a large tape. And put on the oil tank cap to prevent secondary pollution, and put it in a proper position to avoid knocking.
