Fuel systems in agricultural machinery primarily rely on diesel engines, making proper diesel purification essential for engine performance and longevity. There are three effective methods for diesel purification. First, purchased diesel should be allowed to settle for at least 96 hours to let impurities sink to the bottom. Second, when refueling, it's recommended to use a filter and place a layer of fine silk cloth over it to trap additional particles. Third, when drawing fuel from a drum, a similar method can be applied by using a layer of silk cloth or wax paper, which should be cleaned or replaced regularly to maintain efficiency.
It is also crucial to use clean, approved lubricants. The oil filter elements should be cleaned periodically. For rotor-type filters, attaching a suitable piece of kraft paper—either wide or narrow—helps in capturing dirt more effectively through centrifugal force. When cleaning the filter cartridge, it's best to use an air pump to blow out the dirt from the inside out, followed by brushing with a soft brush. Never touch the filter with your hands to avoid contamination.
When using calcium-based grease, always ensure it's clean and avoid mixing it with other types of lubricants. This helps maintain the integrity of the machine’s moving parts.
For the air system, the engine typically draws in 2 to 4 cubic meters of air per minute. To ensure the air entering the cylinder is free from contaminants, the air filter must be inspected and cleaned regularly. A clogged or dirty air filter can significantly reduce engine efficiency and cause damage over time.
Regarding the cooling system, it's best to use soft water such as rainwater, snowmelt, treated tap water, or clean well water. To keep the cooling system clean, you can add 1% caustic soda and 0.5% kerosene to the water. This mixture helps prevent scale buildup and keeps the system operating smoothly.
Most agricultural machinery operates outdoors, often in dusty, muddy, or wet environments. As a result, the machine's body is prone to getting dirty quickly. Regular cleaning is necessary to prevent rust and corrosion. If needed, repainting the affected areas can help protect the metal and extend the life of the equipment. Keeping the machine clean not only improves its appearance but also ensures better performance and longer service life.
