Changing hoses and fittings
Problem: Changing hoses and fittings on tanks usually requires complete draining, or playing the old "how fast can you swap" game.
Problem: Changing hoses and fittings on tanks usually requires complete draining, or playing the old "how fast can you swap" game. The first is time consuming and possibly expensive, and the second is dangerous if dealing with certain types of materials. Is there a third choice?
Solution: Plumb a vacuum generator into the air pressure port at the top of the pressure tank using the existing air supply and a quick disconnect for supply. This approach quickly evacuates the tank of air, creating just enough vacuum to hold the material in the tank, and pulls material back into the tank through the lines. Hoses can be changed and fittings replaced or repositioned with minimal downtime using just one employee.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
