To keep the cleaning of agricultural machinery accessories 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.Agricultural Machinery Parts
Scale removal method
1, in addition to scale. When the scale of iron casting cylinder is removed, the concentration of 8% ~ 10% hydrochloric acid and 3% hydrochloric acid amount of the solution can be heated to 50 ~ 60 ℃ after pouring into the water jacket, soaking 2 ~ 3 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, and the residual acid solution. And then rinse with water several times, until the clean so far.Agricultural Machinery Parts
2, with caustic soda solution in addition to scale. Remove the silicate as the main component of the scale, the 2% to 3% of the caustic soda solution can be added to the cooling system, the locomotive driving 1 to 2 days after the release, rinse with water, so repeat 1, and finally with water thoroughly Clean the cooling system.Agricultural Machinery Parts
Oil removal method
1, 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. 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.
2, the 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.
3, aluminum alloy cleaning fluid 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. Generally use sodium silicate or sodium carbonate solution plus a small amount of potassium dichromate to prepare, heating to 60 ~ 70 ℃ can get the best results.Agricultural Machinery Parts
Coke removal method
1, 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.
2, chemical method. The parts immersed in the preparation of a good chemical solution, until the coke softening loose, and then remove the parts, with a brush or cotton wipe, washed with hot water can be.
