Dual Point Aeration Blower Control

By Tom Jenkins, President, JenTech Inc.; Jun Inai, Senior Design and Project Engineer, and Hayato Sakamoto, Principal Project Leader, Kawasaki Heavy Industries

Historically, the most common dual point control has been combining inlet guide vanes and variable discharge diffuser vanes. These are both mechanical systems and predate the availability of economical variable speed control. Recent advances in power electronics technology and improved VFD economics have led to implementing other combinations for dual point control. These include combining VFD control with either VDVs or IGVs.

Advanced Aeration Control for Blowers

By Tom Jenkins, President, JenTech Inc.

The ideal blower control matches the blower airflow to the process demand. The process demand, in turn, must be established by the aeration control system. This control strategy has become standard practice in most treatment facilities because of its proven effectiveness in reducing energy consumption and improving process stability.

Centralized vs. Point of Use Vacuum Filtration

By Jamie Stebbins, Solberg Manufacturing

In this article, we will isolate and review one system common to many plants and industries: the vacuum system. Within this system, we will further drill down to the filtration required to maintain a healthy process, which contributes directly to the bottom line. The vacuum system does not exist in many production process lines without filtration. Throughput and quality of the end product are closely tied to the necessary vacuum levels achieved when filtration is properly deployed.

7 Best Practices for Leak Detection in Vacuum Systems

By Sinja W. Stentoft, Editor Communications, Busch Vacuum Solutions

Leaks in vacuum systems can cause considerable damage to sensitive industrial processes. The vacuum pump’s ability to generate and maintain the desired vacuum level is compromised as the process gas escapes the pump or contaminants – such as air, dust and debris – enter. This leads to accelerated wear and tear of internal components such as seals and gaskets, and the vacuum pump may fail or require more frequent servicing. As a result, energy bills and overall operating costs increase drastically, while output quality suffers.

Vacuum Receivers: Full of Vacuum or Full of Myth?

By Jackson Redline, Engineered System Solutions Project Manager, Rogers Machinery

In this article, we’ll discuss some of the uses for receiver tanks for positive pressure systems where the pressure inside the system is greater than atmospheric pressure, and the uses, or lack thereof of, receiver tanks in vacuum systems where the system pressure is less than atmospheric pressure.

VFDs Improve Multistage Blower Performance

By Tom Jenkins, JenTech and Lee Pinkerton, Metropolitan Council Environmental Services

Many designers and operators believe that multistage centrifugal blowers are not suitable for variable speed control. They also feel that multistage centrifugal blowers are an inefficient option for wastewater aeration. Implementing VFD control of their aeration blowers allowed the plant to improve energy efficiency. The reduction in energy expense paid for the system upgrade in less than two years.

The Future of Vacuum Automation for AMRs and AGVs

By Markus Schmider, Industry Segment and Key Account Manager Robotics & Composites, Schmalz

Autonomous Mobile Robots and Automated Guided Vehicles can automate receiving and unloading, picking, stacking, storing and even inventory management. However, there are challenges to powering these vehicles and their attachments. Because they are smaller and lighter, the size of components and the power they need to operate matters. Most AMRs and AGVs are battery operated, so it’s important to balance the need for high efficiency with also providing high levels of torque.

Boosting Process Vacuum Performance at a High-Tech Electronics Plant

By Bryan Jensen, Corporate Projects Manager, Rogers Machinery Company

Electronics applications typically run their tooling requiring Process Vacuum based on differential pressure from barometric; that is, they control their PVAC pumps to “Inches of Mercury Vacuum”. This is because the parts and pieces being manipulated by vacuum are of certain sizes, shapes, and weights. If the differential pressure across the part is not great enough, then the tooling will fail and result in a loss of product, adverse impact to quality, and production downtime.

Measuring Blower Airflow Rates with Calibrated Ammeters

By Tom Jenkins, JenTech Inc.

One definition of “calibrate” is “to determine, rectify, or mark the graduations of something”. An ammeter is an instrument for measuring electric current. Therefore the simple definition of a calibrated ammeter is a current measuring device marked with units of measure, presumably amperes. In the blower industry, however, the term has developed a specific meaning. A calibrated ammeter is an instrument that measures a blower motor’s current draw and converts the measurement to a display of blower airflow rate.

Fresh Food and Clay Extrusion Vacuum System Case Studies

By Uli Merkle, Busch Vacuum Solutions

Vacuuming fresh food using chamber machines is often a daily activity in butcher shops, at fresh food counters for meat, sausage, and cheese products, as well as in the foodservice industry. All fresh foods contain more or less unbound water, which partially evaporates during vacuum packaging. This can influence the quality of the product. Furthermore, if the packaging machine is not permanently in operation, the packaging result may deteriorate, or the packaging process may take too long.

Centralized Vacuum System Evaluations: Part 2 Audit Measures

By Hank van Ormer, APenergy

Operating the vacuum system at higher levels (then necessary) affects the needed volumetric flow to compensate for leaks. This required compensation of volume (ACFM) must be added to the nominal production flow demand. The ambient air leak into the system will expand to the highest vacuum level, which is known as the “Expansion Ratio.”
