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.
Slurry pumping is an essential process in various industrial sectors including mining, construction, and wastewater treatment. A slurry is a mixture of solid particles and liquid, which can vary widely in properties, making the choice of pump critical for efficiency and effectiveness. In this article, we will explore the types of pumps used for slurry applications, their working principles, and the factors to consider when selecting the right pump.
In the world of industrial machinery, compressors play a crucial role in various applications, from manufacturing to energy production. Among the many types of compressors, the 185% compressors stand out due to their efficiency and reliability. In this article, we will delve into what 185% compressors are, their importance, and how they contribute to operational success in various industries.
In theater, the tableau takes on an entirely different dimension. It serves as a staging technique where actors create a living picture, freezing in dynamic poses to convey emotions and pivotal moments in the narrative. This technique has been particularly prominent in classical theater, where a single scene can encapsulate the essence of a play. The tableau vivant, or living picture, engages the audience's imagination, compelling them to derive meaning from the stillness and the relationships portrayed among the characters. This method not only enhances the visual experience of the performance but also deepens the audience's emotional engagement with the story.
Mining has been an integral part of human development and industrialization, providing essential minerals and resources that fuel economies worldwide. Among the various operations involved in mining, drilling plays a pivotal role in the extraction and exploration processes. Drilling machines have significantly transformed the mining landscape, enhancing efficiency, safety, and productivity.
(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank
