NL400 Water Well Drilling Rig Features:

1.The series of drill rig adopts a excavator crawler chassis and has strong off-road performance.

2. independent module design allows the drill to be mounted on the truck to increase its mobility. Two speeds of rotating and advancing speed can meet the different needs of soil and rock drilling. Combined positioner, the positioning disc can be adjusted and replaced according to different types of drill pipe and impactor, so as to ensure the accuracy and reliability of the positioning and centering.

3.The hoisting mechanism is convenient for hoisting of drill pipe and impactor, so as to reduce the labor intensity.
4.This machine can be applied to various strata, used in water well engineering, geothermal well, anchor pile hole and so on, and can be used with follow-pipe drilling. It has the advantages of whole machine hydraulic control, automatic loading and unloading drill pipe, crawler type chassis, large horsepower diesel engine, four hydraulic support leg balance, stronger terrain application ability and so on.


NL 400 drilling rig Application scope


The pneumatic drilling rig is multifunction, with different configurations suitable for different geologies.Accept customization,any good ideas please contact us, our engineers will help you get what you want, we can also put the platform on a truck mounted chassis Cr


Structure and working principle


1. Chassis rubber wheel chassis. Drag to walk.
2. The frame of frame welding structure is welded on the chassis.
3. The carriage with welded structure adopts hot-rolled carbon channel steel and square steel pipe as the guide rail of the swivel head,
The oil cylinder is controlled to rise and fall smoothly through the one-way throttle valve.
4. The slewing mechanism is composed of hydraulic motor and slewing reducer. Two high-performance low-speed high torque hydraulic horses
To drive the rotary reducer, you can obtain different torque and speed.


What should be paid attention to when using DTH bit?


1. according to the rock conditions (hardness, corrosion) and drill type (high wind pressure, low wind pressure) to choose the drill bit.

Different forms of alloy and cloth teeth are suitable for drilling different rocks.

Choosing the right drill bit is the premise to get the best use effect;

2. When installing the drill bit, gently insert the bit into the drill bit bit sleeve of the drill bit impactor. Do not force collision to avoid damaging the drill bit

In the process of rock drilling, it is necessary to ensure that the pressure of air on the drilling rig is sufficient;

3.In case of intermittent work , the compressed air system of the drilling machine should be checked to ensure that there is no rock slag in the hole during the drilling process;

4. If a metal object is found falling into the hole, it should be pulled out with magnet or other methods in time to avoid damaging the bit;

5.Pay attention to the size of the hole drilled when replacing the drill bit.

If the bit diameter is too worn out but the hole has not been drilled, do not update the bit to avoid sticking.

The operation can be completed with old drill bits that have been used and worn out to approximately the same diameter
