Construction machinery

There is a lot of rain in summer, so be careful not to get internal injuries to your construction machinery!

Summer is rainy, especially in temperate and subtropical areas, where rainfall is abundant. Construction machinery is easily exposed to water and rain if it is not paid attention to during construction. Not only will it cause corrosion of some components and damage to electrical components, this water enters the engine and fuel system. It will also bring internal injuries to your machine.

Sulfides contained in rainwater will cause corrosion of related parts of construction machinery engines

Rainwater contains a lot of bacteria and various corrosive substances, just like eating bad things can cause gastrointestinal damage. These substances are mixed into daily fuel with high sulfur content, which will bring about the acid-base balance of the fuel system. The corrosion and abrasion of fuel contact parts will bring great hidden dangers to the use of construction machinery in the future.

The infiltration of water will make the engine parts of the construction machinery running at high speed lose its protection

Many parts of the engine need to move at high speeds at high temperatures. If water penetrates into them, not only will the viscosity of the fuel drop, but the increase in friction will also cause the high-speed movement of fuel injectors, oil pumps, and various shaft valves to continue to produce a large amount Heat directly causes deformation and damage of related parts.

Impurities and inorganic salts in rainwater can cause blockage of the fuel system

The mixing of a large amount of rainwater with impurities in the fuel will not only reduce the viscosity and lubrication effect of the construction machinery oil, but also make the surface of the filter element of the fine filter unable to form a good oil film to assist the filter to filter out the impurities, causing the large particles to pass through. The filter element causes the function of the filter element to fail. Many parts of the engine are exposed to danger, so as to cause internal injuries to the fuel system of the entire construction machinery and even the engine.

Rainwater mixing into the engine and fuel system will not only directly damage the fuel injectors and other components, but also cause damage to invisible key components such as engineering machinery engine bearing valves and oil pumps. In order to avoid internal injuries caused by water ingress of construction machinery, attention must be paid to local weather changes during construction, and the parking and maintenance of construction machinery in summer must be paid attention to.
