1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
Sump pumps play a crucial role in managing water accumulation in basements, crawl spaces, and other low-lying areas of buildings. Particularly relevant in regions prone to heavy rainfall or flooding, these pumps are designed to remove excess water that can lead to property damage and potential health hazards. However, this article will delve into a specific aspect of sump pumps their application in the evacuation of mud and sediment, a process essential for maintaining clean, dry, and safe environments.
Submarine hammer drilling represents a significant advancement in underwater drilling technology, offering effective and efficient solutions for a variety of applications. Its capacity to penetrate tough materials, versatility in use, and adaptability to different projects underscore its importance in maritime engineering and natural resource exploration. As industries continue to evolve and adapt to the demands of underwater construction and resource extraction, submarine hammer drilling will undeniably play a pivotal role in shaping the future of marine operations. The continued research and innovation in this field will likely expand its capabilities and applications, ensuring that it remains a crucial technique in the modern engineering landscape.
First, the classification of drilling RIGS:
1, according to the use of the address is not the same, the drill can be divided into underground and open air two categories. According to the presence or absence of traveling structure, the drilling rig can be divided into self-propelled type and non-self-propelled type. There are many open-pit drilling RIGS in China, most of which are self-propelled.
2, according to the aperture is not the same, the drill can be divided into light drilling rig, medium drilling rig, heavy drilling rig.

In the realm of heavy industries, where the transport of abrasive and viscous fluids is commonplace, the ZJ slurry pump has emerged as a pivotal solution. Known for its durability and efficiency, the ZJ slurry pump addresses the specific challenges associated with moving slurries, which are mixtures of solids and liquids, often used in mining, mineral processing, and construction.
Slurry pumps are vital for transporting mixtures of liquid and solid particles, commonly found in mining, construction, and agricultural applications. Unlike standard pumps, slurry pumps must withstand harsh conditions, such as high wear rates from abrasive materials like sand, gravel, and metals. The design of these pumps, especially their blades, plays a crucial role in their efficiency and durability.
