Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.

2. Drill String The drill string is a series of interconnected pipes that transmits drilling fluid and rotational force from the surface to the drill bit. It consists of drill pipes, heavy-weight drill pipes, and drill collars. The drill string must be robust enough to withstand the high pressures and stresses encountered during drilling.

Чулуу бутлуур нь барилга, зам барилгын салбарт хэрэглэгддэг чухал төхөөрөмж юм. Энэ төхөөрөмж нь том хэмжээний чулуу, хүдэр зэрэг материалуудыг жижиг, зөөлөн хэсгүүдэд хуваах, бутлах зориулалттай. Чулуу бутлуурын плита нь энэ төхөөрөмжийн гол бүрдэл хэсэг бөгөөд бутлах процессыг амжилттай гүйцэтгэхэд чухал үүрэгтэй.

The hammer itself can be operated using a pneumatic or hydraulic system, with hydraulic hammers being the preferred choice in most cases due to their consistent performance and reliability. The drill bit used is often designed specifically for marine environments, featuring reinforced materials and cutting edges optimized for hard substrates.

In mining applications, high density slurry pumps play a crucial role in transporting mineral slurries from the processing plant to the tailings storage facility. Their robust construction and efficient design help minimize downtime and maintenance costs, ultimately improving productivity and profitability for mining companies.
In the construction industry, high density slurry pumps are utilized for handling concrete mixtures, grout, and other construction materials. Their ability to handle high-density slurries with ease ensures smooth and efficient operations, leading to faster project completion times and cost savings.

Whether in mining, construction, or waste management, the ZJ slurry pump proves to be more than just a piece of machinery—it is a cornerstone of operational excellence in an increasingly competitive industrial landscape.

Moreover, the environmental sector has also adopted the use of 20mm drill rods for soil testing and environmental assessment. These applications are vital for understanding contamination levels, groundwater flow, and other environmental factors that influence land use and development projects.

(1) If the horizontal slurry pump causes a blockage of solid hard deposits in the volute, measures can be taken to remove the blockage.
(2) If the shaft is different from the stuffing box axis, it is mainly due to processing errors and incorrect installation. Then pay attention to check whether the installation is correct after installation. If the sealing water ring is badly worn, a new water ring needs to be replaced. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, resulting in rapid wear of the packing, resulting in material leakage, you should dredge the blocked water pipe and keep the sealing water clean.
(3) If the impeller or the inlet and outlet water pipe is blocked, the impeller or pipe can be cleaned, and if the impeller is seriously worn, it should be replaced. If the filler mouth leaks, press the filler. If the conveying height is too high or the tube loss resistance is too large, the conveying height should be reduced or the resistance reduced.
