AC Drilling Rig

タイトルまたは説明

It is designed and manufactured according to API Spec Q1, 4F, 7K, 8C, RP**0 and other specifications.²The main equipment (drawworks, rotary table and mud pump) of rigs is driven by AC frequency conversion motor, which realizes the stepless speed regulation of drawworks and rotary table, and the motor adopts AC frequency conversion digital control.²It adopts parallelogram integral hoisting substructure, which can realize low-level installation of table top and derrick and holistic hoisting in place depending on the power of drawworks.² The main brake of drawworks adopt hydraulic disc brake, the auxiliary brake adopts dynamic braking, and it is equipped with an automatic driller.² The rotary table adopts an independent driving structure, which is placed under the rig table top, so the rig operating space is large.
