Also, it is more problematic to t a labyrinth seal to these units, and a standard oilseal could leak lubricant into the process. Given these requirements, the apparently simple planetary solution begins to look increasingly expensive. Drawing on its extensive experience in this sector, Brevini provided a solution to cover all application requirements, in time and in budget. Drive effi ciency The Brevini drive arrangement was deemed to be far more e• - cient, generating the required output from a much smaller prime mover. The Brevini drive has an electric motor, a plane- tary gear unit, a nal-stage slew- pinion and bearing, plus sup- portive steelwork. With no separate method of torque limitation or monitoring speci ed, Brevini proposed to utilise the motor supply current as the generator of the torque level. While this is, technically, the least accurate position, the total combined drive e• ciency of 86% is an improvement over the original drive. Brevini o„ ered this option in part due to the application requirement, where a normal torque-limiter would not have been suitable, in case the system might stall or be disengaged. Once the solution was approved, the new drives were installed safely to MS2JV requirements – delivered, installed, completed and works- tested ahead of schedule. ReŽ ecting on the project, Andrew Baggaley, a' ermarket manager at Brevini UK, says: "We're delighted with the suc- cess of this project. With an original brief that had a very tight deadline for completion, we needed to look at a novel solution for replacement and improvement of the original drives. "Given the nature of the pro- ject, working with hazardous gases and other safety concerns, we worked to the highest safety standards, and the highest standards of PPE, a capability that we at Brevini are very proud of. That we were able to improve on the original speci cation, while still delivering ahead of schedule, is testament to the expertise of our engineers and the breadth of the range of prod- ucts we have at our disposal."
