Precautions For Cleaning Eccentric Reducers

The chemical composition of Stainless Steel Concentric Reducer stainless steel will keep the surface of the eccentric reducer from being corroded and rusted for a long time. Correct cleaning of the eccentric reducer can improve its performance and extend its service life.

1. Use alkali cleaning, water-soluble cleaning agent, chlorine solvent sandblasting, shot blasting and other methods to clean according to the requirements of the workpiece and the surface condition;

2. Clean the eccentric reducer, generally do not use the acid pickling method to clean it.

The welding rod should be kept dry when used. The titanium calcium type should be dried at 150℃ for 1 hour, and the low hydrogen type should be dried at 200-250℃ for 1 hour (it cannot be dried repeatedly, otherwise the coating will crack and peel off easily). Prevent the welding rod coating from sticking oil and other dirt, so as not to increase the carbon content of the weld and affect the quality of the weldment. When welding elbows, carbides are precipitated by repeated heating, which reduces corrosion resistance and mechanical properties. The hardening property after welding is large and cracks are easy to occur. If the same type of welding rod is used for welding, preheating above 300℃ and slow cooling at about 700℃ after welding must be performed. If the weldment cannot be heat treated after welding, chromium-nickel stainless steel welding rods should be used.
