    ST 400 Pneumatic Borewell Machine Features

    1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.

    2. The drill rig has more positive speed stages and 14-500r / min speed range, and the output torque is 13428-250N.m.
    3. The drilling rig has 2 reverse speeds, which is convenient for handling accidents.
    4. The air compressor drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 3400MM to improve drilling efficiency and reduce the occurrence of plugging and burning accidents.
    5. The water well drilling rig rig uses dual oil pumps for oil supply. A single pump is used for drilling, and a double pump is used for confluence when lifting. The power loss is small and the auxiliary time is short.
    6. The drilling rig machine has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.
    7. The crawler water drilling rig machine chassis is adopted, and the trip of the outrigger
    cylinder can be automatically loaded for 1.5m, which is convenient for relocation and transportation.
    8. The drill rig reserves some functional interfaces in the hydraulic system, and can expand the functions according to the technological requirements of different users.

    What is the construction technology of de watering well?


    Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → de watering completion, pipe pulling → well sealing.

    Precautions for drilling machine working at low temperature


    1. In the low temperature environment, the land will become hard, so when we choose the site, we need to have some requirements. The site needs to be flat and the road needs to be unblocked. This must be ensured.

    2. The drilling machine mainly uses triangular support, especially in the case of low temperature, we should ensure that the support of the drilling machine is firm and reliable. Our staff need to regularly check and deal with hidden dangers in time once they are found. We must not be careless

    3. Although we work at low temperature, we can not ignore the problem of fire prevention. The configuration of fire-fighting equipment must be reasonable and meet the fire-fighting requirements.

    4. Low temperature, low temperature, what is the most important? Of course, our friends should pay attention to their warmth when working. Only when they are warm can we better put ourselves into work.

    5. The temperature is low, which will definitely have certain impact on the construction. We must pay attention to warmth and safety
