At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

2). Features:
1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
3, simple and easy to move, the weight of the drill machine is less than 500Kg, and can be broken down into three pieces, easy to move and put on the shelf.
4, the selection of rolling drag plate, the track is not easy to wear.
5, the drilling machine uses semi-automatic cloud dynamic disassembling drill pipe, high efficiency.

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.

  • 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.
