1. Earth Drilling Bullet teeth are ideal for drilling through dense and rocky soils. Their robust design allows operators to bore holes for foundations, utility poles, and other structures without compromising efficiency.

The primary function of a drainage pump is to collect and remove water from a specified area. Most commonly used in basements, crawl spaces, and construction sites, these pumps are equipped with a float switch that activates the pump when water reaches a certain level. Once the water is detected, the pump will turn on, drawing the water into its casing and expelling it through a discharge pipe to a designated drainage area. This process continues until the water level drops below the float switch, at which point the pump turns off.

Maintenance Considerations

Problem: The pump does not produce water, and the vacuum gauge indicates a high vacuum

Conclusion

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.
