On a global scale, organizations working on water access initiatives emphasize the importance of sustainable practices in water well drilling. This means not just focusing on immediate access to water, but also considering the long-term implications of groundwater extraction. Over-extraction can lead to depletion of aquifers, land subsidence, and deterioration of water quality, which is why responsible management practices are essential. Awareness campaigns, training programs, and community engagement are vital components of these initiatives, ensuring that local populations are equipped to manage their water resources wisely.

The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

  • 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.
