When used for a long timeFlower planterDirt or oil stains will be generated in the accessories of the rear equipment. If the dirt is not completely cleaned, it will have an adverse effect on the use of the machine. But how do we clean it up? How can we effectively remove the dirt on the planter? Let's follow the editor to understand it.

1. Descaling method

When removing the scale from the cast iron cylinder. Heat 8-10% hydrochloric acid and a corrosion inhibitor equivalent to 3% hydrochloric acid, and inject it into the water jacket at a temperature of about 50-60°C. After immersing for 2 to 3 hours, the corrosion inhibitor is released. Then wash with potassium dichromate aqueous solution, or inject 5% sodium hydroxide aqueous solution into the water jacket to neutralize the residual acid solution, and then rinse with clear water repeatedly.

Remove scale from the cooling system. The main component of these accessories is silicate, so add 2% to 3% sodium hydroxide aqueous solution to the cooling system, let the machine run for half a day, and then rinse it again and again with clean water until it is taken out. .

2. Oil removal method

Remove animal and vegetable oil and mineral oil from the surface of the part, and remove them with an alkaline solution. A small amount of emulsifier can be added to the lye. 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 solutions will corrode high-pressure fuel pumps, fuel injectors and other precision parts. Therefore, organic solvents (including gasoline, kerosene, alcohol, etc.) should be used to clean the oil stains in these parts.

Remove the oil on the aluminum alloy parts. Alkaline solution has a strong corrosive effect on aluminum alloy, but organic solution is 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.
