ST 50 Trailer Mounted Drilling Rig Feature
1. Equipped with double oil cylinder hydraulic feeding system, the drilling speed is fast and the working efficiency is high.
2. The drilling rig is equipped with a fixed clamping mechanism and an integrated main rod
3. Equipped with 4-speed transmission system. The operator can freely adjust the forward rotation speed through three gears, and is also equipped with a slow reverse gear, which is convenient for the operator to disassemble the drill pipe and drill tool.
4. The handle is centralized, easy to operate, safe and feasible.
5. It is equipped with a pressure gauge at the bottom of the hole to indicate the pressure
6. It has strong decomposition ability and is easy to move. It is suitable for working in hilly, mountainous and other complex terrain.
Rural Water Wells Aspects
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.
