Why is your hydraulic cylinder moving slowly?
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…
Compressed air fail: Air-oil separator failure
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 […]
Where and when should you use wire-reinforced hose?
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 […]

Troubleshooting challenge: Low pressure halts digger derrick truck movement
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…
Why use point-of-use dryers with compressed air systems?
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 […]
