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.  

In the ever-evolving fields of mining and construction, the need for efficient, precise, and powerful drilling techniques is paramount. Among various methods, down-the-hole (DTH) hammer drilling has emerged as a pivotal technology, providing a range of benefits that enhance productivity and reduce operational costs.

In conclusion, progressive cavity pump slurry plays a crucial role in the industrial equipment sector, especially in the realm of pump and vacuum equipment. Understanding its working principle, applications, and benefits can help businesses make informed decisions when it comes to selecting the right pump for their specific needs.

Die Bedeutung von Sandpumpen

Une barre de forage est un long tube en acier qui est utilisé pour transférer la rotation et le couple du moteur de forage au bit de forage. La barre de forage est généralement conique à une extrémité, ce qui lui permet de se connecter à d'autres barres ou à un bit de forage. Les barres de forage sont disponibles dans une variété de tailles et de configurations, en fonction des exigences spécifiques du projet de forage.

Дизельный воздушный компрессор – это устройство, которое преобразует механическую энергию, получаемую от дизельного двигателя, в сжатый воздух. Такой компрессор может быть использован в самых различных отраслях, включая строительство, горнодобывающую промышленность, металлообработку и многие другие. Модель с производительностью 200% CFM (Cubic Feet per Minute) означает, что компрессор способен выдавать воздух в объеме, в два раза превышающем средние значения, принятые для аналогичных устройств.
