You want to put what where?: Real Life Examples of Navigating Special Challenges of Life Support Equipment
Steven Richie, Aquarium of the Pacific Watch Video (Login required) Full Abstract
The Aquarium of the Pacific is located in downtown Long Beach, California. It opened its doors in June of 1998 and has been evolving ever since. Over the years, the life support team has taken on a large number of plumbing and automation projects. Two of these projects stand out in a unique way in that they required our life support team to get creative in the placement and plumbing of the life support components. The two systems include a stand-alone cylinder tank with LSS components in a nearby closet and an outdoor Jelly Touch system with all major LSS components stuffed into a 4’ wide wedge between a curved retaining wall and the Aquariums perimeter fence. Completing the cylinder tank project included having to build a custom triangular sump and well and a completely vertical build of the life support pieces. The Jelly Touch system require a custom curved concrete sump attached to an existing retaining wall as well as multiple plumbing points to allow for proper cleaning and care of a jelly system. Both of these projects show examples of real world challenges that can arise and how looking outside the box for solutions can lead to successful competition of even the trickiest of projects. |
Performance and Energy Saving Demonstrated Using Magnetically
Coupled Pumps Steve Massar, Vancouver Aquarium Watch Video (Login required) Full Abstract
In an effort to reduce energy costs and address operability issues with vacuum DE filters, the Vancouver Aquarium installed FLUX Drive magnetic couplers on a variety of filter pumps up to 40 hp. These were chosen over VFDs or throttling the pump discharge. The existing DE filter installation requires that the flow be reduced as vacuum increases to minimize incipient cavitation or pulling air past the shaft packing. Tests were performed to determine which pump control would perform best. The FLUX drive system demonstrated similar energy consumption compared to the VFD controlled pump. Mechanical heat transfer was reduced as indicated by a 1C drop in measured temperature. Other installations have been successful in eliminating bearing damage due to induced electrical current where VFDs were previously used. This type of drive could be beneficial for many pumping applications. |
