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.  

4. Эффективность Дизельные компрессоры обладают высокой топливной эффективностью, что позволяет снизить эксплуатационные расходы в долгосрочной перспективе. Несмотря на то что первоначальные инвестиции могут оказаться высокими, экономия на топливе и обслуживание часто окупает эти затраты.

2. Rock drill: used to drill holes with a diameter of 20 ~ 100 mm and a depth of less than 20 meters in rocks above medium and hard. According to its different power can be divided into pneumatic, internal combustion, hydraulic and electric rock drill, of which pneumatic rock drill is the most widely used.

Downhole drilling equipment plays a pivotal role in the exploration and extraction of natural resources such as oil, gas, and minerals. This specialized equipment is designed to operate in the harsh and challenging environments found deep beneath the Earth’s surface. As the demand for energy and minerals continues to rise, advancements in downhole technology have transformed the efficiency and safety of drilling operations.

The Manufacturing Process

DTH hammer drilling is widely utilized in various sectors, including

1. 효율성 디젤 엔진은 다른 연료에 비해 연료 효율성이 높습니다. 이는 장시간 동안 작업해야 하는 건설 현장에서 특히 중요한 요소입니다. 덕분에 작업자는 연료 비용을 절감할 수 있습니다.

3. Environmental Assessments Environmental scientists often employ submarine hammer drilling to collect sediment cores and geological samples from the seabed. This data is essential for assessing the health of marine ecosystems and understanding sedimentology for future projects.
