First, prepare the right concentration. The effect of metal cleaning agent is related to the concentration of cleaning solution, but when the concentration increases to a certain value, the cleaning performance will not be significantly improved. Different parts should be prepared with different concentrations of cleaning solution. Cleaning general parts, the concentration of 2% ~ 3% is appropriate; Cleaning heavy-duty parts, the appropriate concentration is 5%; When cleaning the rear axle gear and shaft parts, the concentration is preferably 3% ~ 4%.

Second, don't use ineffective cleaning agents. Pay attention to the shelf life when buying and using, and don't use invalid cleaning agents. Metal cleaning agents should be prepared quantitatively, as soon as possible. If the amount of waste cleaning liquid is small, the environmental pollution is small; If the quantity is large, it will pollute the environment and need to be treated with waste liquid. Agricultural machinery parts should be dried or dried before use after cleaning.

Third, the correct cleaning method. After the cleaning solution is prepared, two cleaning containers should be used for rough cleaning and fine cleaning respectively. Before cleaning, scrape the parts with thick dirt and carbon deposits on the surface, then soak them in a rough washing container for a certain period of time, and then wash them from rough to fine. When cleaning, clean the precision parts first, and then clean the general parts. When cleaning the waterway and oil circuit of crankshaft and other parts, it is best to use a pressure gun or other injection tools for pressurized flushing. After cleaning for a certain period of time, the cleaning liquid in the fine washing container should be poured into the coarse washing container, and then replaced with clean cleaning liquid to ensure the quality of fine washing. When ultrasonic cleaning equipment is used, the pH value should also be checked. If the pH value is less than 7, cleaning agent should be added to ensure the cleaning quality.

Fourth, master and control the temperature. In a certain temperature range, metal cleaning agent is beneficial to the dissolution of grease and grease. Therefore, cleaning should be carried out in strict accordance with the appropriate temperature range specified by various metal cleaning agents. General parts can be cleaned at room temperature in summer, and properly heated or prepared with warm water in spring and autumn. When cleaning heavy-duty parts with heating B in winter, the temperature should be raised appropriately. If JD- 1 103 cleaning agent is used and the temperature is controlled between 65℃ and 70℃, the cleaning effect will be better. Heating can be done by soaking water or directly heating water, depending on the specific situation.
