ST 300 Meters Customized Water Well Drilling Rig Equipment Features:
1. The speed range of the drilling rig is 14-1030r / min, and the maximum output torque is 9500n. M.
2. The drilling rig adopts long travel speed doubling mechanism and mechanical power head with a stroke of 3500mm, which is used to improve drilling efficiency and reduce drilling plugging and burning accidents.
3. The drilling machine is in mechanical operation. Some functional interfaces are reserved in the hydraulic system, which can be expanded according to the process requirements of different users.
ST 300 Customized Water Well Drilling Rig Equipment Woking Attentions:
During the working process of water well drilling rig, the pump is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive the drill bit to rotate for drilling. The negative pressure established by the suction of the mud pump sucks the debris mud into the inner cavity of the drill pipe and discharges it into the sedimentation tank through the mud pump.
Drill rigs are coated with anti-rust liquid naked, drill pipes are bundled and packed, impactors, drill bits and other accessories are packed in plywood boxes.
