ST 200 Water Well Drilling Rig Applications
The utility model relates to an efficient and multifunctional drilling equipment, which is mainly suitable for drilling wells, agricultural irrigation wells, ground source heat pump wells and other wells, especially for water intake projects in mountain areas and rock formations. The drill can be used for drilling in different formations, and the maximum drilling diameter can reach 350mm.
The drilling rig adopts new hydraulic technology, supporting large torque hydraulic motor rotation and large-diameter hydraulic cylinder propulsion. The engine of the famous factory provides power for the hydraulic system. The two-stage air filter and the intake design of the compressed air lead extend the service life of the diesel engine. The unique pump unit design facilitates maintenance and reduces maintenance cost. Centralized control hydraulic console for easy operation.
Four aspects of rural water wells
1, Select appropriate well type
The well types of water source wells are divided into deep wells, large wells, counterpart pumping wells, foreign wells, and small-diameter tube wells. In areas with abundant deep groundwater, it is appropriate to drill deep wells. In areas with abundant shallow groundwater, it is appropriate to drill large wells, counterpart pumping or small-diameter tube wells.
2, Reasonable well layout
The location and layout of wells shall be reasonably arranged according to the local actual hydro geological conditions. If there is no hydro geological data, refer to the existing water source wells around as the basis for the layout of wells. In areas where shallow groundwater is not abundant, shallow wells should not be drilled blindly; In areas with abundant shallow groundwater, it is suitable for farmers to build their own shallow wells, but the well hole layout should not be too dense to avoid the interaction between adjacent water source wells.
3, Configure appropriate water pump
After the well is completed, measure the water level of the water outlet well and the corresponding water output according to the drainage condition of the drilling machine, and then determine the total head of the water pump according to the height difference from the ground to the dynamic water level and the irrigation method you adopt, and the required working head of the water pump. The flow of the water pump shall not exceed the water flow through the well. The corresponding water pump shall be purchased on the premise of the above two items.
