Several Ways To Remove Dirt From Agriculture Machinery Parts

  Several ways to remove dirt from Agriculture Machinery Parts:

  ◆ 1, the removal of dust

  Compressed air blowing method. On the adhesion of the dirt is not strong, you can use compressed air to sweep the surface of parts, will cover the parts of the dust, iron and other debris clean.

  Manual removal method and tool cleaning method. Use nylon brush, metal brush, scraper, hook and other tools, with manual way to clean up, and then use cotton fabric, Agriculture Machinery Parts synthetic fiber products, white silk cloth and other parts of the dust to wipe clean the surface. The brush, scraper installed on the power tools, relying on mechanical power can quickly remove parts of the surface dirt.

  High pressure water cleaning method. Rely on high-pressure water guns, rotary cleaning machines, general-purpose washing machines and other equipment to produce high-speed flow generated by the impact of kinetic energy, the parts surface, dead ends, blind holes and cavity parts of the dirt rinse.

  Abrasive jet method. In the water mixed with abrasive, the formation of solid and liquid mixed media, the mixed medium in the form of high pressure spray to the surface of the parts, Agriculture Machinery Parts high pressure water and abrasive impact dirt layer after the dirt layer crushing, and parts of the surface rinse.

  ◆ 2, the removal of oil

  2.1, organic solvent degreasing

  Organic solvents can be a good solution to the surface of a variety of oil on the surface, so as to achieve the purpose of cleaning. Commonly used organic solvents are gasoline, kerosene and diesel. With organic solvent degreasing process is simple, no heating, no damage to the metal. But the high cost of cleaning and flammable, only for small and medium-sized maintenance enterprises and temporary repair. Large and medium-sized maintenance enterprises can use synthetic metal cleaning agent. Some companies use trichlorethylene in addition to oil, Agriculture Machinery Parts the practice proved good results, but the environment has a certain degree of pollution, the operator's health have a certain impact.

  2.2, electrochemical degreasing

  Electrochemical degreasing, also known as electrolytic degreasing. In this way, the part is placed in the electrolytic cell containing the degreasing solvent as the cathode, and the steel plate with good alkali resistance is placed in the electrolytic cell as an anode. In the role of direct current generated by electrochemical reaction, with the bubble generated in the cathode on the oil film tearing to remove the surface of the oil surface. Electrochemical degreasing is usually used in the current density of 5 ~ 15A / d resistance, operating voltage 6 ~ 8V, operating temperature 60 ~ 80 ℃, duration 15 ~ 30min. When the part material is high strength alloy steel, Agriculture Machinery Parts in order to prevent hydrogen absorption caused by hydrogen embrittlement phenomenon, the oil parts should be connected to the anode.
