Electric Fertilizer Spreader Oil Removal Method

  • When using an Electric fertilizer spreader, once used for a long time, the attachment will produce dirt or oil. If it is not completely removed, it will have a bad effect on the use of the machine. But how do we clean it up? How can the dirt in the planter be effectively removed? Below, follow the editor to understand clearly.

    One, descaling method

    When removing the scale at the cast iron barrel. Heat 8-10% hydrochloric acid and a corrosion inhibitor equivalent to 3% hydrochloric acid and inject it into the water jacket at about 50℃-60℃. After immersing for 2 to 3 hours, the corrosion inhibitor is released. Then wash with potassium dichromate aqueous solution, or inject 5% caustic soda aqueous solution into the water jacket to neutralize the residual acid solution, and then rinse with clean water repeatedly.

    Remove scale from the cooling system. The main component of these parts is silicate, so add 2~3% caustic soda water solution to the cooling system, wait for the locomotive to drive for 1/2 day, and then rinse again and again with clean water until it is removed.

    1. Oil pollution removal method

    Remove animal and vegetable oil and mineral oil from the surface of the part and remove it with an alkaline solution. The lye can be added with a small amount of emulsifier. After heating, use pressure cleaning or injection, and then rinse the residual liquid on the surface of the part with warm water.

    Remove oil from precision parts. Alkaline solution has a corrosive effect on high-pressure oil pumps, fuel injectors and other precision parts. Therefore, the oil stains in these parts should be cleaned with organic solvents (including gasoline, kerosene, alcohol, etc.).

    Remove oil from the aluminum alloy parts of the Manual fertilizer spreader. Alkaline solutions have a strong corrosive effect on aluminum alloys, but organic solutions are expensive and not suitable for large-area use. Therefore, the oil stains of these components can be removed with aluminum alloy cleaning fluid. The specific preparation method is that potassium dichromate is added with a small amount of water glass or sodium carbonate solution, heated to 60°C-70°C and used.
