    Advantages of drilling rigs


    1. Small and light, convenient for high altitude geological operations;

    2. The hydraulic automatic feeding mechanism is adopted to improve the drilling efficiency and reduce the labor intensity of workers.

    3. The vertical shaft box 4 sets ensure that the gyrator has sufficient rigidity to deal with complicated terrain conditions such as gravel layer and pebble layer;

    4. It adopts national patent taper clutch, which has large transmission torque, convenient operation and maintenance-free.

    Five Main Steps of Hydraulic Dewatering Rig


    1. Check the water and pipes frequently. The bolts and nuts at different parts of the drill are very solid.

    2. Be sure to check the condition of fan oil.

    3. When the working face is immersed in water, use a large diameter drill bit to insert the drill pipe when inserting the hole, and make the surface of drill pipe 1 prevent mud and slag from falling into the hole. 2 meters.

    4. During drilling operation, the drilling rig is not allowed to turn in the afternoon to prevent the drill pipe from falling into the borehole.

    5. After the drill stops working for a short period of time, apply a small amount of pressure to prevent sand from entering the drill hammer. If the drilling rig stops for a long time, the impactor should be lifted 1 to 2 meters from the bottom of the well to prevent the drilling tool from being covered by mud.
