To ensure the effective operation of a sump pump designed for mud evacuation, regular maintenance is crucial. This includes routine inspections, cleaning out the sump basin, checking the float switch, and ensuring that the discharge line is clear of obstructions. Neglecting these maintenance tasks can lead to pump failure, potentially resulting in severe flooding or mud accumulation.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
