Description of Hydraulic Control System Components

The hydraulic control system is a completely self-contained system. A 10-horse power, 1800 rpm, AC motor, drives two hydraulic pumps and powers the hydraulic system. A fixed displacement pump drives the lube oil system motor. A variable displacement pump provides hydraulic power for the AC motor brakes, powered rotating head, remote actuated IBOP, pipe backup clamp cylinder, link tilt, and counterbalance system. Three hydropneumatic accumulators are located on the main body.

The hydraulic manifold attaches to the main body and contains solenoid, pressure and flow control valves.

A sealed stainless steel reservoir supplies hydraulic oil, eliminating the need for draining and refilling during normal rig moves. The reservoir is mounted between the AC drilling motors and is equipped with strainers and an oil level sight gauge.
