In addition to its agricultural benefits, water well drilling plays a crucial role in infrastructure development. Urban areas are often overburdened with the demands of a growing population, leading to issues such as water shortages and reliance on insufficient municipal supplies. By investing in drilling projects, cities can enhance their water security and reduce their dependence on external sources, which can often be unreliable. Furthermore, establishing decentralized water systems through well drilling can help improve resilience against climate-related disruptions.

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.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
