High pressure cleaning machine is one of the commonly used cleaning equipment in the field of rail transit. It utilizes high-pressure water jet technology to generate high-pressure water through a high-pressure pump, and converts the pressure energy into highly concentrated water jet kinetic energy through a nozzle, thereby completing the cleaning of the surface of rail transit equipment. High pressure cleaning machines can remove oil stains, rust, paint and other pollutants, and have the advantages of high cleaning efficiency, no pollution, and no corrosion. In the field of rail transit, high-pressure cleaning machines are mainly used to clean key components such as axles, bogies, tracks, gearboxes, brake discs, etc., ensuring the surface cleanliness of these components and improving the service life and safety of the equipment.

Ultrasonic cleaning machine is also one of the commonly used cleaning equipment in the field of rail transit. It utilizes the cavitation effect of ultrasound in liquid to generate tiny bubbles that quickly close, resulting in a water hammer effect that forcefully flushes the surface of objects. Ultrasonic cleaning machine has the advantages of good cleaning effect and powerful function, which can remove various stubborn dirt. In the field of rail transit, ultrasonic cleaning machines are mainly used to clean train components such as engines, brake pads, gears, as well as precision parts of rail transit equipment. Through ultrasonic cleaning, the surface cleanliness of these components can be ensured, improving the performance and safety of the equipment.

When choosing a cleaning machine, various factors need to be considered in the field of rail transit, including the material of the cleaning object, the type of dirt, and cleaning requirements. At the same time, it is also necessary to consider the performance parameters of the cleaning machine, such as pressure, flow rate, temperature, etc. In practical applications, the operation and maintenance of cleaning machines are also very important. Operators need to be familiar with the operating procedures and precautions of the cleaning machine to ensure its normal operation and cleaning effectiveness. At the same time, it is necessary to regularly maintain and upkeep the cleaning machine to extend its service life and performance.
