By Josh Cosford, Contributing Editor In part 5 of this series covering hydraulic oil analysis, we move on to discuss acidity. As it pertains to hydraulic oil, we need to know the total amount of acidic substances found within the sample. Most commonly referred to as the Total Acid Number, or TAN for short, the […]

By Josh Cosford, Contributing Editor If your hydraulic cylinder is moving slowly and you’re reading this article, your cause is not likely a lazy operator. Your situation is obviously one where an expected performance isn’t being met, or there was a sudden and dramatic slowdown of your cylinder velocity. Diagnosing the cause of a cylinder…

  A compressed air auditor regularly flow-tested the compressors under his study. This generally would be done if the air compressor was drawing low amps — a telltale sign that the unit is producing low flow output — or if the compressor has excessive hours. Often times, internal wear due to age will reduce output […]

By Josh Cosford, Contributing Editor Hydraulic hoses come in many sizes and designs, and the expression of each design is a result of the purpose of that hose. Generally, there are three common locations where a hose is used in a hydraulic system: suction lines, working lines and return lines. Each location has its own […]

Contributed by Robert Sheaf, Founder of CFC Industrial Training In this month’s challenge, we go out into the utility world, where digger derrick trucks operate to prepare worksites. Here, a digger derrick truck could not operate any function that required pressure above 50 psi. The pump load sense was set at 300 psi with the…

It is common to see the air in a complete plant dried by a desiccant dryer only to service one small end-use that is subject to freezing temperatures. The purge from a large desiccant dryer is much more costly than that of a small point-of-use dryer, which can be placed on the outdoor feed. The […]

At iVT Expo last week, Sun Hydraulics was highlighting some of its newer technologies, including its eSense counterbalance solution. This load-holding technology allows users to save energy without sacrificing performance. Designated as part of Sun’s ecoline program, this solution adapts to any load and provides up to 85% of energy-efficient power to applications. Combatting the […]

By Josh Cosford, Contributing Editor In the bustling battlefield of pneumatic systems’ hose and tubing, two contenders stand ready for combat: polyethylene and nylon tubing. Armed with unique strengths and weaknesses, they prepare to face off in the high-pressure war, so let’s dive into this skirmish and see who emerges victorious. Round 1: The Durability […]

Proportion-Air is expanding its proportional electro-pneumatic pressure and flow control into the testing equipment field with its newest product, the Proportion-Air Supply. This benchtop unit for lab or manufacturing use is designed to regulate compressed air and other gases within prescribed pressure and flow limits for easy use. Suitable for developing, testing, and diagnosing pneumatic […]

Operator comfort and ergonomics are significant considerations in mobile machine design.

Features include: Can be fully sealed up to IP69K Rated […]

Unitized sealing solutions feature over-molding and precision machining to eliminate challenges inherent in standard piston and gland designs. Contributed by Andrew Iddeson, Product Technology Director, Advanced Sealing Technologies and Chuck White, Global Product Development Manager Hydraulic cylinders are a key component in efficiently harnessing the power created by a fluid power system into usable linear […]

In linear motion applications, pneumatics, servo pneumatics, and controlled pneumatics each deliver unique motion and force capabilities. Contributed by By Frank Langro, Director of Product Market Management, Pneumatic Automation, Festo Pneumatic linear actuators are fundamental for automation because of their low cost, ease of installation and operation, high yet compliant force, speed, compactness, safety in hazardous areas, […]

Contributed by Gary Molton • BSc, Owner, Engineering Adventures Poor assembly or using the wrong type of fluid power fitting has been shown to increase risk of fluid leakage and industrial injury. Fitting designs have changed considerably over the last 30 years to reduce these risks but this has resulted in a myriad of assembly […]

Compactness is crucial for many equipment applications, with machine builders aiming for smaller parts that maintain high power. Finnish hydraulic motor manufacturer Black Bruin launched its new X-series for such applications, including recycling, marine and offshore, construction, mining, and material handling. With its patent-pending design, the company aims to enhance the performance, durability, serviceability, and […]

A compressed air auditor was excited to see logbooks for each of the compressors at a large mineral processing facility. Each book was protected from the environment by a really nice orange plastic case. The auditor was interested to see the compressor history and opened the book, only to discover it was blank — no […]

By Josh Cosford, Contributing Editor Comparing electrical with hydraulics is one of my favorite topics to write about. When you study both fields, you quickly realize how much the concepts, mathematics and symbology coincide. However, not all readers share my same enthusiasm for the analogy. Many years ago, one LinkedIn member commented that I was […]

By Josh Cosford, Contributing Editor If you’re not terribly familiar with hydraulic fittings, you may think BSPT is a typo. Is it supposed to be BSPP (British Standard Pipe Parallel) or perhaps NPT (National Pipe Thread)? No, it’s not a typo – we’re actually talking about British Standard Pipe Taper, which is the version of […]

A compressed air auditor recently performed an energy audit at a mineral processing facility. Plant personnel were constantly complaining about production outages due to low pressure. The problem was that when the pressure dips down below 80 psi, the drive clutches on the large ball mills — that grind the processed down minerals to powder […]

A compressed air auditor found, during a site visit to a mine, that compressed air condensate was left to drain from stopcock at the bottom of piping low spots. The oily condensate pooled on the ground, creating a slippery mess that polluted the environment and caused a safety hazard. This mine had no air dryers […]
