FLUID POWER: Daniel E. Cook, president and CEO of Proportion-Air Inc. recently announced the introduction of the new MizAir® energy savings device for Air Operated Double Diaphragm (AODD) pumps. The product will save up to 50 percent of the energy used by AODD pumps.AODD pumps use a tremendous amount of compressed air to operate and are notoriously inefficient. The most effective way to make AODD pumps more energy efficient is to better manage the air they consume. The obstacle has always been that no two AODD pumps are the same, making it nearly impossible to design a product that consistently works. Until now.
MizAir is a patent protected electro-pneumatic “smart” device. It uses “fuzzy” logic to analyze each stroke of the pump and “learns” the pump’s unique characteristics. MizAir then automatically makes internal adjustments to reduce the air consumption of the pump by as much as 50 percent, therefore reducing the energy required to run it by the same amount with little to no effect on pump throughput, fluid flow or flow rate. On approved pumps, no pump modification is necessary. MizAir is literally plumbed to the air input side of the pump and provided with 24V dc power.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
