Dredger maintenance

 Dredgers mainly suck the mud through a suction pump, so the suction 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 dredge pump of the dredger must be subject to regular maintenance work, so that it can be ensured that the suction dredge pump can perform higher power during excavation work.
  1. Smoothness of suction pump
  Suction pump is made of smooth oil to make bearing parts to operate. If there is no smooth oil, the friction coefficient between the various parts will increase, and if it is severe, the risk of seizing the tiles will also occur. Therefore, we must regularly apply the smooth oil to the suction pump in daily operation 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 lot 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 a waterproof paint, the waterproof paint will show different degrees of falling even if it is 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 varying degrees of wear, so it is often necessary to regularly check and protect the blades. If it is found that the blades are worn out, new blades should be replaced immediately so that the suction pump can function normally.
