Development and implementation of drill rig hydraulic drives
(2007) Artymiuk, Jan; Bednarz, Stanisław; Falbo, Giuseppe; Małozięć, Tomasz
Rotary and translatory motions are a basic form of transforming other type of energy on mechanical energy in the driving systems. The proper use of fundamentals of hydromechanics decides about the design and build of the driving systems, hydraulic systems with hydraulic control. Technical feasibility, especially tightness of hydraulic systems, is of big importance. This factor has been a drawback in the power hydraulics applications for years. A higher reliability of sealings caused a fast development of hydraulic drives. Hydraulic drives as the advantages have wide possibilities of control and transmission of drive to long distances, high efficiency, relatively simple design of control elements, possibility of making still and flexible drives as well as direct connection of the motor with the working machine or its sub-assembly. These drives require qualified attendance and strict following instructions and technical procedures. The dynamic torque of hydraulic drives is considerably higher than in other types of drive, resulting in short time constants of the system. Hydraulic Drillmec rigs have been supplied for different applications (oil, gas, geothermal and water researches) and tested in many field conditions - besides workover operations yet - confirming the flexibility, reliability and good performance of this idea. They are operating all around the world having a number of technical advantages.
