1. Manual Cleaning: For impellers with light dirt, manual cleaning can be used. First, apply a suitable amount of cleaning agent to a brush and carefully scrub the impeller surface, focusing on the blades and hub. During scrubbing, be careful to use moderate pressure to avoid damaging the impeller surface. Then, rinse the impeller thoroughly with clean water to remove any residual cleaning agent and dirt.
2. High-Pressure Water Gun Cleaning: When the dirt on the impeller surface is thick, a high-pressure water gun can be used. Aim the nozzle of the high-pressure water gun at the impeller surface, starting from the edge and gradually moving towards the center, evenly rinsing all parts of the impeller. During the cleaning process, be careful to control the pressure and angle of the high-pressure water gun to avoid excessive pressure that could damage the impeller. Simultaneously, ensure that the cleaning water fully covers the impeller surface for a good cleaning effect.
3. Immersion Cleaning: For some stubborn oil stains and impurities, the impeller can be disassembled and immersed in a container filled with cleaning agent. Soaking time depends on the severity of the dirt, generally ranging from several hours to a day. During soaking, the cleaning agent can be stirred appropriately to accelerate the dissolution of the dirt. After soaking, remove the impeller and rinse it thoroughly with clean water.
