Agricultural Machinery Parts Cleaning And Maintenance Tips
Agricultural machinery parts cleaning and maintenance tips
To keep the cleaning of Agriculture Machinery Parts for the normal operation of agricultural machinery is very good, but the different dirt in the treatment is indeed very difficult, the following describes several ways to clear the dirt dirt for reference.
1 scale removal method
Remove the iron cast cylinder and other scale, the concentration of 8% -10% hydrochloric acid and the amount of hydrochloric acid equivalent to 3% of the Jodi corrosion inhibitor solution heated to 50-60 ℃ after the injection into the water jacket, Hour after the discharge, and then add potassium dichromate aqueous solution for cleaning, or with 5% concentration of caustic soda solution into the water jacket, Agriculture Machinery Parts and the residual acid solution. And then rinse with water several times, until the clean so far.
B In addition to caustic soda solution
2% -3% caustic soda solution is added to the cooling system, Clean the cooling system.
2 oil removal method
A alkaline solution to remove oil
On the surface of the animal and vegetable fats and oils and fines and oil can be removed, can be used to add a small amount of solid solution into the emulsifier, after heating and cleaning. Agriculture Machinery Parts If the use of pressure jet, the effect is better. After cleaning, and then heated water spray, rinse off the surface of the residual alkali solution.
B organic solvent to remove oil
In order to prevent the alkali solution on the precision parts (such as high pressure oil pump, injector, etc.) corrosion, generally can use organic solvents (such as gasoline, kerosene, alcohol, etc.) for cleaning.
C aluminum alloy cleaning solution to remove oil
Alkaline solution has strong corrosion effect on aluminum alloy, and organic solvent cost is high, so in the cleaning of aluminum alloy parts, can be prepared aluminum alloy cleaning solution. Agriculture Machinery Parts Generally use sodium silicate or sodium carbonate solution plus a small amount of potassium dichromate to prepare, heated to 60-70 ℃ can get the best results.
3 Coke removal method
A mechanical method
Can be used metal brush, blade and other tools to remove carbon deposition. But this method is easy to scratch the surface of the parts, so the removal of precision parts on the coke should be used wood or bamboo scraper to clear, but also in the cork on the back and forth friction clearance. After removal of carbon from the parts by mechanical means, the oil should be carefully cleaned. This method is simple to operate, the shortcomings are difficult to access the site is not easy to clean.
The parts immersed in the preparation of a good chemical solution, Agriculture Machinery Parts until the coke softening loose, and then remove the parts, with a brush or cotton wipe, washed with hot water can be.
