Maintaining the Changsha photovoltaic pile driver is a crucial task, of which cleaning is a part. During the construction period, the pile driver is exposed to a relatively large amount of dust. Without cleaning, and with dust accumulating over time, the wear on the Changsha photovoltaic pile driver will accelerate. Water is used for washing, but it cannot effectively remove oil stains. Let's take a look at common cleaning solutions and their characteristics. First, there are chemical cleaning solutions, which are chemically synthesized aqueous solutions (mainly surfactants) with strong degreasing abilities. They first need to wet the components with additives to prevent corrosion and rust. These solutions penetrate the dust-contacting surfaces to dissolve the dust on the surface of parts and dissolve it in the cleaning solution. The most common chemical cleaners include LCX-52 water-based metal cleaner, JSH high-efficiency metal cleaner, D-3 metal cleaner, 817-C oil cleaner, and CJC-8 liquid metal cleaner, among others. The second type is organic solvent cleaners, which can dissolve various types of oils without the need for heating, are easy to operate, do not damage metals, and have very good cleaning effects. They are non-oily, petrol, alcohol, but have some drawbacks, such as being commonly flammable and expensive, more suitable for precision parts such as plastics, nylon, and other materials, but rubber parts cannot be cleaned with organic solvents.

The third type is alkaline solution cleaners, which use emulsifiers to emulsify non-saponifiable oils and have a degreasing effect, making them the most widely used cleaning liquids. Emulsifiers can be added to alkaline solutions to form emulsions. The surface tension and adhesion of the oily film cause the oily film to break into very small droplets and prevent them from adhering to the surface of metal parts to achieve a degreasing effect. Common emulsifiers include water glass, xanthan gum, and synthetic detergents. When cleaning parts with an alkaline solution, the solution should first be heated to 80-90°C, followed by cleaning. After degreasing, rinse with hot water to remove any alkaline liquid remaining on the surface of the parts to prevent corrosion. Everyone should choose the appropriate cleaning solution based on the various parts and materials of the pile driver. The degree of corrosion of alkaline solution cleaners to metals varies, especially since they are corrosive to aluminum, so they must be heated before cleaning. Organic cleaning solvents are mostly flammable. Pay attention to storage conditions. Do not use organic solvents to clean rubber parts. To protect and lubricate, it is best to apply a bit of oil after cleaning the Changsha photovoltaic pile driver.
