1000m water well rig belongs to water well rotary drill rig truck. Its components are mounted on the "HOWO” brand truck. Most parts of the machine adopt hydraulic driven and the other part is mechanical driven. In addition to the main operating mode of rotary drilling, the1000mwater well rig can be adapted to other drilling mode if it is equipped with drilling tool which is suitable for drilling through various strata such as clay, sand and matrix etc. At the beginning of boring, pressuring mechanism is used by water well drill rig truck to promote the efficiency of shallow-hole drilling. With the increasing depth, when the weight of the drill tool is greater than the pressure required applying to the drill tool, the main hoisting system should be used to carry out reduced pressure drilling.
