About dredger suction pump maintenance

 Dredgers mainly suck the mud through suction pumps, so the suction dredge pump is the center of the dredger. Especially on the cutter suction dredger, it is totally relying on the suction pump to pick up the sludge. Therefore, the dredger's suction pump must be subject to regular maintenance operations, so as to ensure that the suction pump performs higher efficiency in excavation operations.
  1. Smoothness of suction pump
  Suction pump is made of smooth oil to make bearing parts to work. If there is no smooth oil, the friction coefficient between the various parts will increase, and if it is severe, the risk of holding the tiles will also occur. Therefore, in the daily use, we must regularly modify the suction pump with smooth oil, so as to ensure the normal operation of each component.
  2. Corrosion protection
  Suction pumps are often exposed to mud and water during the operation process. A large amount of muddy water is splashed on the pump for a long time. If it is not protected for a long time, the pump casing will be oxidized. Although the exterior of the pump casing is painted with waterproof paint, the waterproof paint will show different degrees of shedding when used for a long time. Therefore, it is necessary to regularly paint waterproof paint, and also to do a good job of suction pump waterproof operation.
  3. Blade replacement
  After a long period of use, the blades will also exhibit different degrees of wear, so it is often necessary to regularly check and protect the blades. If it is found that the blade wear is severe, it is necessary to immediately replace the new blade so that the suction pump can function normally.
