Design concept:
MWT-300 water well drilling rig is specially designed for water well project construction. MWT-300 with its strong reliability, high efficiency of well completion, and relatively simple structure, not easy to damage, easy to operate and other characteristics, by the customer's praise.
Depth:
The depth that drilling equipment can reach is related to the bearing capacity and lifting capacity of the drilling tower
Bearing capacity determines the number of drill pipes that can be used. The greater the bearing capacity is, the more drill pipes can be used, so as to achieve deeper drilling depth.
The lifting force determines the weight of the drill pipe that can be lifted. The greater the lifting force is, the more drill pipes can be lifted, so as to reach a deeper drilling depth.
With good bearing capacity and lifting force, the drill pipe with larger inner diameter can be used to increase drilling efficiency.
Drill tower form: integrated welding forming telescopic type
Material: Q345B high temperature and low temperature resistant
Structure: after 30 years of practical use, no problem, all parts are strengthened welding. With auxiliary rack
Parameters: the bearing capacity of the drill tower is 30t, and the actual bearing capacity is 50t.
Advantages: the drill tower is very firm, it can use more drill pipes, and it can use the drill tower itself to carry out the construction operation of lowering the well pipe. It has a very strong anti torsion performance, and it is not stuck or buried for the complex formation.
Lifting form: special pressure reducing cylinder for construction machinery.
Lifting force: 25t φ 89 drill pipe as an example) each meter weighs 20kg, and the 300 meter drill pipe weighs 6T. When lifting the drill pipe, the friction and reverse resistance at the bottom of the hole must be calculated, and the lifting force of 25t is enough to meet the depth requirements of 300-400M
Advantages: hydraulic valve control, accurate operation, large lifting force. In drilling construction, the equipment must have strong lifting force. If the lifting force of the equipment is not strong, the drill pipe cannot be forced out when the hole bottom collapses or shrinks. Especially in the use of air DTH hammer drilling, it is very easy to bury the drill and collapse the hole, our equipment has a strong ability to get rid of difficulties.
