Off-the-shelf reverse circulation multifunctional water well drilling rig

Full hydraulic control is convenient and flexible
The rotation speed, torque, thrust axial pressure, reverse axial pressure, thrust speed, and lifting speed of the drilling rig can be adjusted at any time to meet the needs of different drilling tool operating conditions and different construction processes

Top drive rotary propulsion lift
It is easy to connect and unload the drill pipe, shorten the auxiliary time, and also facilitate the drilling with the pipe.

multifunctional drilling
Various drilling techniques can be used on this rig, such as: DTH drilling, through air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, roller cone drilling, pipe drilling and Core drilling in development and more. The drilling rig can be equipped with mud pump, foam pump and generator according to user needs. The rig also comes standard with a variety of winches.

High working efficiency
Due to the full hydraulic and top drive rotary propulsion lifting, it is suitable for various drilling processes and various drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so the operation efficiency is high.

low cost
The drilling on the rock is mainly based on the down-the-hole hammer drilling process. The down-the-hole hammer rock drilling operation efficiency is high, and the drilling cost per meter is lower.


high outrigger tracked
The high outriggers are convenient for loading and transportation, and can be loaded directly without a crane. Crawler walking is more suitable for muddy field movement.

Positive and negative axial pressure adjustment
The best impact efficiency of each impactor has its optimum shaft pressure and rotation speed. During the drilling process, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more matching axial pressure. The impact efficiency is higher at this time.

The role of the lubricator
Efficient and durable lubricators and oil mist pumps. During the drilling process, lubricate the impactor running at high speed all the time to maximize its service life.

Rig chassis
It can be a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis.


The value of second-hand mobile phones in the same industry is higher
As the main components of the drilling rig are imported brands, and the main frame of the drilling rig is made of high-quality high-strength low-carbon alloy steel, which increases the overall strength and is very wear-resistant, as well as the more important hydraulic system, which is very valuable.
