400M Hydraulic Well Drilling Rig Sales Of Water Well Drilling Rigs For Engineering
Introduction of crawler type Crawler Mounted Drill Rig
Water gas dual-purpose drilling rig is a mechanical top drive
drilling rig integrating water drill and air drill. It effectively
solves the problems of difficult drilling with air DTH hammer in
soil layer and low efficiency of water drilling mud in hard rock
layer, gravel and pebble layer.
The drilling rig is suitable for various complex strata, drilling
and geological exploration, drilling core, high efficiency and
energy saving. It is the inevitable trend of equipment development
in water well drilling and geological engineering exploration
industry in the future.

Operation of well drilling machine when adding drill pipe
1. When the depth of one drill pipe needs to be connected after
drilling, stop the propulsion first, then stop the rotation, and
turn off the cooling water;
2. Stop the rotation and operate the fast forward and backward
handle to the fast backward position to make the chuck quickly back
in place; 3. The gyrator reverses, at the same time, it retreats
the feed oil cylinder to rotate the water braid shaft away from the
drill pipe;
4. Operate the clamping handle to make the gripper clamp the drill
pipe and open the micro regulating flow valve (right rotation)
5. Connect the drill pipe to be added to the previous drill pipe,
and the rotator moves forward while rotating. When the trapezoidal
conical thread of the water braid shaft is in screw contact with
the conical thread of the newly added drill pipe, immediately
operate the gripper handle, loosen the gripper and complete the
drill pipe addition.
Drilling rig characteristics
1. The drilling rig has advanced structure and reasonable layout,
which is easy to maintain, maintain and repair.
2. The drilling rig has many positive speed stages and 14-500r /
min speed range, and the output torque is 13428-250n. M.
3. The drilling rig has a reverse speed of 2 gears, which is
convenient to deal with accidents.
4. The drilling rig adopts long travel speed doubling mechanism and
mechanical power head, with a travel of 3400mm, which is used to
improve drilling efficiency and reduce the occurrence of drilling
plugging and burning accidents.
5. The drilling rig adopts double oil pump for oil supply, single
pump for drilling and double pump for confluence during tripping;
Less power loss and short auxiliary time.
6. The drilling rig is mechanically driven and the others are
hydraulically driven, making effective use of power. The overall
power loss is small and the drilling cost is low.
7. The crawler chassis is adopted, and the leg oil cylinder has a
stroke of 1.5m, which can be loaded automatically and is convenient
for relocation and transportation.
8. Some functional interfaces are reserved in the mechanical
hydraulic system of the drilling rig, which can be expanded
according to the process requirements of different users.
