Rotary Drilling Rig

Digital Hydraulic Rotary Drilling Rig


Precision Rotation Control of Digital Hydraulic Motor

The rotary drilling rigging requires frequent rotation and accurate positioning, and the rotary inertia reaches tens of tons-meters. At present, there is no automatic control system, which can only be realized through the experience accumulated by the operator for many years and with highly centralized control. 

The rotary drilling rig driven by AEMETEC's digital hydraulic motor realizes high precision repeated positioning and slow start and slow stop, which not only greatly improves the operation accuracy and efficiency, but also reduces the fault and fuel consumption, and cooperates with the digital hydraulic motor crawler control, Combined with DGPS, automatic drilling operation can be realized.

▉ Rotation error: + /-0.2 degrees

▉ Rotation speed: + /-0.2 ~ 60 degrees / second


Precision Control of main Winding of Digital hydraulic Motor

By using the digital hydraulic motor to control the main winch and release cable, not only the slow start and slow stop can be realized, but also the length of the cable corresponding to the rotation angle of the digital hydraulic motor can be accurately controlled, at the drill pipe can be slowed down and braked accurately when the drill pipe is played back, it can greatly improve the efficiency of operation and reduce the incidence of accidents.

▉ The main winch speed can be adjusted arbitrarily from rest to maximum and realize slow start and stop.

▉ The length of hoisting wire rope can be measured accurately.

Precision Crawler Control of Digital hydraulic Motor

The precise operation control of bilateral crawler controlled by digital hydraulic motor can not only realize rapid positioning, but also cooperate with DGPS to realize automatic drilling operation.

▉ Moving speed error: + /-0.5%

▉ Displacement error: + /-10 mm

Digital hydraulic Motor and Digital hydraulic cylinder provide innovative guarantee for Automation and Intelligent Operation of Construction Machinery
