Blowing a jet of compressed air at an object is a common but “poor” use of compressed air. Often the blowing nozzle is a piece of pipe on a hose with a manual valve for control. This quickly solves a production problem when a more efficient factory made nozzle is either physically too big, too expensive, or not on site when needed. Retrofitting with factory made nozzles is often ruled out by for the same reasons, and the time needed by managers and fitters to change a nozzle for often little gain in production.
In this article, we will provide detail on the characteristics of the baseline system and then share the energy-saving work identified in two projects. These two projects represent work which can be performed by the maintenance teams in every plant. These are also project opportunities we find in almost every plant we visit. The two projects are to (1) repair/replace condensate drains wasting compressed air and (2) to perform a compressed air leak survey.
If your vacuum pump is malfunctioning, you are faced with a choice: repair or replacement. Our guide will take you through both options and provide recommendations on when it makes sense to repair vacuum pumps and when to replace them. We will also take a look at how to spot and diagnose common issues before they lead to system failure.
Whatever the path of action, the decision to repair or replace always begins with testing and diagnosis. A factory-trained service technician who specializes in vacuum pump services inspects the equipment and identifies the problem.
The impact of compressed air on industries globally is undeniable, spanning from small tire shops to vast oil and gas sectors, as well as specialized domains like laboratories and pharmaceuticals. Amid this industrial transformation, many have taken control by employing in-house air compressors, air dryers, and related equipment to autonomously generate compressed air. In-house compressed air generation eliminates the need for relying on external sources, whether through cylinder bulk packs, Dewars, or tankers delivering compressed air.
Industrial ceramics have been produced in Hermsdorf, near Jena, since 1890. In the past, high-voltage insulators; now, ceramic honeycomb bodies for heat exchangers, ventilation and emission control systems. They have always kept up with the times, developing innovative materials, products and state-of-the-art production processes to do so.
Laird & Company has been pioneering and perfecting Applejack brandy for 325 years. In 1698, William Laird immigrated from County Fyfe, Scotland to Monmouth County, New Jersey, bringing nothing but the distillation skills of his homeland with him. Keen to experiment with the ingredients of the New World, William began to dabble in the distillation of the most abundant crop in the area – apples.
This article dealt with all the various conditions that can and do affect the performance capacity of various types of air compressors in actual flow capacity (SCFM at site conditions).
Over the last two decades, there has been a significant increase of manufacturing facilities deciding to produce their own nitrogen on-site, using compressed air systems and nitrogen generators. They are choosing on-site nitrogen generation, instead of purchasing and receiving deliveries of nitrogen by the cylinder or having a “Nitrogen Over the Fence” supplier.
A ‘Process’ application, is one where it’s all about controlling the contents of a vessel, pipeline, or chamber. What is the gas makeup inside the vessel? How much of it is in there? All means to control a chemical and/or thermodynamic reaction so that we add value to some base ingredients to convert them into a marketable product.
There were two situations brought to our attention. The first was that production at times was having to slow down, or even stop, due to compressed air system pressure falling below the required levels. The second reason was due to reports, from plant personnel, of compressed air moisture problems negatively affecting the bag life of the dryer baghouses.
This assessment identifies a path to reduce the energy consumption from \$85,000 to \$51,000 per year. This can be done with little capital by fixing poppet-valve control problems on the air compressors and reducing flow and pressure requirements. Due to article space limitations, this article does not provide detail on the flow reduction projects. It focuses only on the impact these projects have on the air compressors and provides readers with a template on the information they should have on their units, by shift.
