Primer On Wind Turbine Energy From US Department of Energy

This video is entitled “Energy 101: Wind Turbines – 2014 Update” and is really informative. It comes to us via the U. S. Department of Energy.

The video starts out by explaining how creaky, old windmills on farms (used to mill grain or pump water or both) were the predecessors for new, modern wind turbines that generate electricity.

The same wind that used to pump water for cattle is now turning giant wind turbines to power cities and homes.

Wind Power Creates Electricity

The principle of today’s enormous wind turbines remains the same – that is to capture wind’s energy which is free and convert it to electricity. This electrical energy is used to power cities and homes.

A video animation shows how the wind turbine works in simple terms.

The blades of the wind turbine work similar to those of an airplane wing. Air waves pass along either side of the blade. It is the blade’s shape that causes the air pressure to be uneven. That pressure is higher on one side of the blade while lower on the other. This uneven pressure causes the blade to spin around the center of the turbine.

The wind turbine’s blades attach to a shaft which connects to a series of gears which increase the rotation. At a high enough speed this starts to produce energy.

A weather vane sits on the top of the wind turbine. The weather vane is connected to a computer which turns the turbine into the wind so it can capture the maximum amount of energy.

Why wind turbines are so tall.

That’s simple. The higher up the windier it gets. And more wind naturally means more electricity.

Larger turbines also can capture wind energy more efficiently. The long blades can sweep a circle in the sky.

Even small wind farms are capable of generating enough electricity to power thousands of homes. Larger farms provide much more clean energy for our businesses and homes.

Another source of wind power lies in our oceans and the Great Lakes. The U.S. Energy Department supports innovative offshore wind projects. This will help build offshore wind turbines in U.S. waters.

Over 50% of the U.S. population lives within 50 miles of a coastline. Thus capturing wind power off of America’s shores can provide energy to countless homes and businesses.

Brake Clutch and Friction Systems Needed In Heavy Industry

Crane Brakes

Crane Brake

A typical braking system applies a (i.e. electromagnetic) force to apply friction, or mechanical resistance. This friction causes heat in its attempt to slow down and even stop a device in motion or to simply maintain it’s position without any motion.

Think of pressing your brake while driving your car. Your foot sends hydraulic brake fluid to a piston which in turn causes each brake pad to apply friction on your tires’ brake discs. The friction slows down each wheel and eventually stops your car.

Heavy Industry Brake, Clutch and Friction Systems

In heavy industry the brake, clutch and friction system is also used to slow and stop passenger or freight trains, wind turbines, cranes or hoists, etc. Even though there many types of brake system designs, their operation remains basically the same – to stop the movement.

When it comes to the selection of a heavy industrial brake, clutch and friction system it is imperative that one understands some key variables. These requisite and relevant variables are most critical to selecting the optimal product for your application.

I suggest there are three primary steps one should take in properly assessing an application.

  1. Recognizing and realizing the application and its fundamentals is the first step in the brake, clutch and friction selection process. To do so, you should identify the industry, application and specific parameters involved for the particular application. Is it a static or dynamic application? What is the operating environment like? (I.E. Is it hazardous?) What is the brake function and requirements? What is the system being used for?
  2. Now you must understand how to use this information and apply it to your specific application. In order to do this, one must fully understand exactly what these variables mean. You must comprehend such concepts as: static vs. dynamic; full motor and mechanical braking torque; friction coefficient as well as several others. These will be paramount when it comes to properly selecting a brake, clutch and friction material.
  3. Once you understand the variables and industry application specific aspects to your application it is time to apply these fundamentals and select your brake, clutch and friction material. You might consider collaborating with application engineers to perform a careful due diligence. This will ultimately lead to a better decision making process.

There are many brake and clutch manufacturers and many options to choose from. Our fast paced and price sensitive society has propelled business culture into often times rushing to decisions. This definitely has not necessarily helped industry as a whole.

At times the least expensive option is not the best alternative nor does the good old boy network work to your advantage. Take your time to investigate your alternatives.

This may help you make the best decision about a capital business expenditure. Ultimately in the long run it may prove to save your company a great deal of time and money.

Finding The Missing Link In The Heavy Industry OEM Process

Heavy Industry Construction Crane

Heavy Industry Construction Crane

An OEM (original equipment manufacturer) manufactures a large piece of equipment for you, the end user. This may be an overhead crane or a gantry crane, a conveyor, stacker/reclaimer or “any equipment used for (non-automotive) heavy industry.

The OEM sells this piece of equipment to an end user. These could be a steel mill, mine, food processing plant, airport, container port, or literally any type of manufacturing entity within an industrial application.

This piece of equipment must do its job regularly and reliably for the end to profit. For example, a steel mill needs an overhead crane to help move material and process in the manufacturing of steel. Without this crane, the process comes to a halt and the job can not be done due to downtime.

An efficiently operating crane is part of the life blood surging through the veins of a successful steel making plant. So it’s only natural for end user companies to want to ensure their equipment runs at optimal capacity ensuring maximum uptime. They also want to keep costs minimal to reduce operating expense and add to their profit margin.

Therefore you might ask: “Does the OEM provide parts and service for this equipment in the long run?”

Not the Core Competency of an OEM

The answer is simply yes. The OEM does provide parts and service. However, it is NOT their core competency.

There are several variables that come into play in this scenario which create the opportunity for a MRO distributor to enter into the scene.

OEMs primarily specialize in making the equipment. They are typically very expensive products that include multiple components such as electrical, mechanical, hydraulic, etc. Some of these OEM’s do not provide the individual components. They neither service nor repair them.

Retrofit and Modernize Good Heavy Industry Equipment

Furthermore, as the heavy industry’s capital equipment ages and depreciates, there comes a definite need to retrofit and/or modernize it. For instance, a crane might be 30-40 years old.

Although it is still fundamentally a good piece of equipment, technology has improved dramatically since it was first put into production throttling efficiency.

Their also might be issues trying to keep the crane in service. The original parts may be obsolete or the OEM no longer provides maintenance manuals or instructions.

At the other extreme replacing the crane is costly and time consuming. The capital investment for a new crane might be close to $2 million alone. Plus there’s the downtime of replacement.

MRO Companies Fill the OEM Void by:

  1. repairing or providing service to an existing piece of equipment at a more affordable price versus replacing it with new equipment.
  2. troubleshooting, providing replacement parts or even reverse engineering a new part (both the latter combined with educating the customer).
  3. analyzing the situation and modernizing the operation. Finding suitable replacements for existing parts and thus making the process more efficient while saving the end user time and money versus buying new.

That is precisely where Kor-Pak Corporation excels if and when you find yourself in one of these situations. Kor-Pak is a service company that fills the void. We can furnish parts no longer available in standard catalogs or provide assistance with technical solutions and problem solving.

Hoist Crane Brakes, Hoist Disc Brakes, Crane Hoist Braking Systems for cranes are imperative for the safety and performance of your crane application.  Whether it be a Ship-To-Shore Crane, Gantry Crane, Overhead Crane, or another crane type, Hoist

Hoist Brake Setup

Hoist Brake Setup

Brakes are vital components of the industrial ecosystem that should be taken seriously and be properly specified and maintain.

To insure best practices for Hoist Brakes for Crane Application, it’s good to get back to the basics.

Hoist Brakes consist of shoe or disc brakes on the high speed side of the motor which are typically Thruster Disc Brakes, Thruster Drum  Brakes, or Magnetic Drum Brakes.  On the low speed side, it is important to have a Emergency Disc Brake system to prevent a load from falling in the event of a low-speed failure, such as gearbox or coupling failure or shaft breaking.

Specifying Hoist Crane Brakes, Hoist Disc Brakes, Crane Hoist Braking Systems

Low-speed brakes for hoist crane brakes applications are specified according to full motor torque plus a service factor.  In the USA this is called out in AISE standards.  The low-speed brakes are either used as dynamic stopping or static holding brakes, depending on whether there is a VFD controlling the motor as a primary brake.  There are several variables that are involved when specifying these brakes such as:

  • Environmental Factors (i.e. ambient temperature, dust/grime, saltwater exposure, etc.)
  • Required torque
  • Friction coefficient
  • Duty Cycle

Emergency Disc Brakes

For the low-speed brakes, the brake(s) typically interface with a disc that is mounted on a flange on the drum.  If this is not possible then the shaft can be extended or other alternatives are available.  The emergency brake system is typically a caliper brake that is magnetic, hydraulic, or pneumatically released.  An encoder can be mounted on the shaft that counts the pulses of the drum to measure the RPM and when a predetermined speed is reached, and “Overspeed Condition” is detected which triggers the E-Brakes to apply via a proportional controlled power unit so the brakes will not come to an “immediate stop” and the brakes will stop the load from falling without creating a “shock load.”

More detailed information regarding Crane Brakes, and specifically hoist brakes for cranes and emergency crane brake can be found in this Technical Paper.  In this paper you will see that Europe has implemented strict standards on the requirement for emergency brakes for hot metal cranes and certain hoist applications, but this is still not a requirement in the USA.  There have been numerous reported incidents of low-speed failures which have resulted in catastrophic failures that are extremely costly and some have caused fatalities.  It is imperative that the USA adopts the same standards as Europe to create safer operating environments.  While there is a cost to Emergency Crane Brake Systems, the benefits unequivocally exceed the costs when it comes to equipment protection, downtime, and most importantly, human lives.
