Today, the manufacturer of Shandong gantry cranes will share with you how many cleaning methods there are for lifting machinery parts?

1. Cold cleaning: Using kerosene, gasoline, and diesel as cleaning agents, place the parts into an oil basin with a mesh screen, rinse with a wire brush, and the oil stains sink into the bottom of the basin through the mesh screen. The cleaned parts can be dried in the air.

It should be noted that when cleaning oil stains on friction plates, a small amount of gasoline should be used to rinse them clean. For oil stains on rubber and leather parts that are not resistant to oil, oil should not be used for cleaning. In order to save oil and achieve better cleaning results, smaller parts with cleaner and more lubricating appearances should be washed first. Then clean the larger parts with heavy oil stains on the surface.

2. Hot washing: Clean by heating with alkaline and emulsifier solutions, as engine oil, gear oil, etc. cannot dissolve in alkaline solutions and can form emulsions. So emulsifiers need to be added to the alkaline solution.

The function of emulsifiers is to penetrate into the interior of the oil layer, weaken the binding force between oil and metal, and promote the rupture of the oil film for separation. The solution needs to be heated to 70-80 ℃, and the parts should be immersed in the solution for boiling. After cleaning the parts, they should be rinsed with water at 60-80 ℃ and then dried in the sun.

3. Chemical cleaning solution: It is an aqueous solution prepared with a chemically synthesized water-based metal cleaning agent. The metal cleaning agent is mainly composed of surfactants and has strong cleaning ability. In addition, there are some auxiliary agents in the cleaning agent that can improve or increase the comprehensive performance of metal cleaning agents, such as anti-corrosion, rust prevention, and carbon removal.

The principle is that the cleaning solution prepared with cleaning agents first wets the surface of the parts, and then penetrates into the interface between the dirt and the parts, causing the dirt to fall off, disperse, dissolve in the cleaning solution, or form emulsions or suspensions on the surface of the parts, achieving the purpose of cleaning the parts.
