Technology and the Future of the Offshore Industry

 

Since oil prices have collapsed in 2014, the North American shale industry has reportedly suffered lower activity levels. However, with more projects offshore that are being restored in 2017, experts are optimistic about the future of the industry. According to a research carried out by Rystad Energy, shale-focused operators are expected to increase spending by 30% in 2017 while offshore spending

Mechanisms of Heat Transfer

 

Heat transfer plays a huge role in the application of the First Law of Thermodynamics, which refers to the application of the conservation of energy principle to heat and thermodynamic processes. The first law is used extensively in the discussion of heat engines. A heat engine converts heat or thermal energy, as well as chemical energy, to mechanical energy.

The Growing Role of Control Valves in Various Industries

 

Control valves are used to manipulate the flow of fluid and are described as possibly the most important, and in some cases the most neglected, part of a control loop. Control valves, aside from heater or other device, are actuated to produce a change in the process variable of a control loop and ensure safe and efficient operation of the process.

Three Common Hydraulic Mistakes

 

Hydraulic systems are of great importance to a number of industries worldwide given the fact that they assist in carrying out tasks that need extensive labor. That said, companies work to ensure that their hydraulic systems are functioning or operating at their very best at all times. Unfortunately, hydraulic systems, just like any other machine can fail to operate efficiently and in most cases, this is because of mistakes made knowingly or unknowingly either by the company’s employees or by those in charge of the hydraulic system. To help you in your quest of having a hydraulic system performing at it’s very best, this post will get to highlight three common hydraulic mistakes made throughout various industries.

The Top Three Causes of Hydraulic Pump Failures

 

Hydraulic pumps, in addition to being one of the most expensive components of a hydraulic system, play a very important role and as such, many facilities, especially ones that use hydraulic systems for their day-to-day critical processes, work tirelessly to see to it that they protect them at all cost. Despite their efforts, many of them fail to take into account well-known causes of hydraulic pump failure and as such, still find themselves dealing with matters hydraulic pump failures that ultimately end up damaging expensive components of their hydraulic system. This post will highlight the top three causes of hydraulic pump failures.

Energy-Efficiency Tips for Compressed Air Systems

 

Compressed air systems are of extreme value to many industrial facilities countrywide. In fact, many facilities (big or small) consider compressed air systems as a “fourth utility” given the part they play in their day-to-day business processes. Despite the benefits, compressed air systems do have one big con and that is energy consumption.

How To Test A Hydraulic Cylinder

 

The conventional way of testing the integrity of the piston seal in a double-acting cylinder is to pressurize the cylinder at the end of stroke and measure any leakage past the seal. This is commonly referred to as the "end-of-stroke bypass test". The major limitation of the end-of-stroke bypass test, is that it generally doesn't reveal ballooning of the cylinder tube caused by hoop stress.

How to Maintain a Hydraulic Steering System

 

Hydraulic steering is a wonderful thing, especially for those of us who remember old-fashioned, jump-the-sheave cable systems or, even worse, the chain-and-sprocket setups popular on sailboats. While some folks (sailors, mostly) criticize hydraulics for the lack of “feel,” others say that’s one of the main benefits: You’re not constantly fighting the pressure of water rushing past the rudder. Even better, hydraulic steering is reliable and demands little maintenance—like a Timex, it takes a licking and keeps on ticking. But you can make the ticking smoother, and ensure against the odd system failure, by adding periodic steering-system checks to your maintenance schedule.

How well do you know your hydraulic fluid?

 

It's no secret demands on hydraulic oil have increased in the past 20 years. Systems are generally smaller, so less oil is used. Pumps have been tasked to produce as much or more output, resulting in higher operating pressures. Smaller oil volume and higher pressures result in higher oil temperatures. Hotter oil temperatures mean an increase in oxidation rates and more thermal stress on the additive system. At the same time, end users want to spend as little as possible for fluid that lasts as long as possible and maintains a high level of protection for the equipment.

How to Improve Hydraulic Efficiency

 

Hydraulic efficiency in terms of hydraulic fluid depends on a few factors, all of which relate to the viscosity of the hydraulic fluid. Low viscosity, either from poor fluid selection or high temperatures, results in a loss of volumetric efficiency, overheating and wear. High viscosity, either from poor fluid selection or low temperatures, results in poor mechanical efficiency, difficulty starting up and wear.

Caring For Your Hydraulic Steering

 

Some marine systems are so reliable we tend not to notice them. I've owned a few boats in my time, and most of them had hydraulic steering. It's one of those reliable systems so widespread, it's all but universal except for boats that use a tiller, cable, or other form of mechanical steering. Good steering systems work as they should, year after year, and typically don't get on the schedule of routine maintenance, unless there is a problem.

How Hydraulics are Applied in Environmental Testing

 

Environmental testing occurs before a construction project gets underway. Technicians carry out a range of tests on the ground so that any issues can be identified and dealt with. Certain factors can affect the feasibility of projects and while they may not prevent work from going ahead, they can determine whether other treatments or preparations are required before construction begins.

Cause of darkening hydraulic fluid

 

"After pulling a fluid sample from one of our hydraulic systems, we noticed that the hydraulic fluid had become darker. We were concerned, so we rushed the sample to the lab for analysis. The results of the fluid analysis appeared normal. The acid number, viscosity and oxidation by FTIR have all remained stable. A quick inspection of the hydraulic system revealed that the hydraulic valves have turned goldish in color. What should we do?"

Hydraulic Contamination Control

 

Proper filtration and monitoring is absolutely paramount in order to keep a hydraulic system operating efficiently and effectively. Up to 80% of all system failures are related to or directly caused by contamination in the system. These system failures always result in increased machine downtime and therefore decreased production. The downtime and lost production are directly responsible for a company’s lost revenue. The added up-front cost to insure proper system filtration and monitoring can easily be justified by having eliminated just one hour of machine downtime.

Why you should clean new hydraulic hoses

 

When I was still very young my mother used to take me shopping with her. Whenever she bought dishes, she would bring them home and wash them before putting them away. That seemed kind of silly to me at the time because, after all, they were brand new! But when I asked her why she did that she said, “You never know where those dishes have been!”

The Seven Most Common Hydraulic Equipment Mistakes

 

There are only two conditions that mandate a hydraulic oil change: degradation of the base oil or depletion of the additive package. Because there are so many variables that determine the rate at which oil degrades and additives get used up, changing hydraulic oil based on hours in service, without any reference to the actual condition of the oil, is like shooting in the dark.

Hydraulics Know-How: Just-In-Case versus Just-In-Time

 

On a recent flight, I listened to an audio recording in which a business coach talked about just in time versus just in case learning. His premise was, when an entrepreneur or manager is starting and/or growing a business, there is much to learn - but the time available to do so is scarce. So this coach's suggestion was to learn what you need to know - as and when you need to know it - something he referred to as just in time learning, as opposed to spending scarce time learning about something which may be useful to know at some point in the future - just in case learning.
