useplanterWhen used for a long time, the attachment will produce dirt or oil stains. If it is not removed, it will have an adverse effect on the use of the machine. But how do we clean it up? How to effectively remove the dirt in the planter? Let us follow the editor of the vegetable planting machine manufacturer to understand clearly.

One, descaling method

When removing scale from the cast iron barrel. Heat 8-10% hydrochloric acid and a corrosion inhibitor equivalent to 3% hydrochloric acid, and then inject it into the water jacket at a temperature of about 50°C to 60°C. After being immersed for 2 to 3 hours, the corrosion inhibitor is released. Then wash with potassium dichromate aqueous solution, or inject a 5% caustic soda aqueous solution into the water jacket to neutralize the residual acid solution, and then repeatedly rinse with water. Remove scale from the cooling system. The main component of these parts is silicate, so please add 2% to 3% caustic soda aqueous solution to the cooling system, wait for the locomotive to drive for 1/2 day, and then repeatedly rinse with water until it is taken out.

2. Methods to remove oil stains

Remove animal and vegetable oil and mineral oil from the surface of the part, and remove it with an alkaline solution. A small amount of emulsifier can be added to the lye. After heating, use pressure to clean or inject, and then rinse the residual liquid on the surface of the part with warm water. Remove the oil from the parts. Alkaline solutions are corrosive to high-pressure fuel pumps, fuel injectors and other parts, so organic solvents (including gasoline, kerosene, alcohol, etc.) should be used to clean the oil stains in these parts.
