Generator Construction

A generator is an industrial machine that converts input mechanical energy produced by burning fuel or other sources into electrical energy as the output. The main moving components in the generator are - Engine and Alternator. The engine produces mechanical energy by burning fuel like diesel, gasoline, propane (in liquefied or gaseous form), or natural gas. The size of the engine is directly proportional to the maximum power output the generator can supply. There are a number of generator engine manufacturers like Yamaha, Honda, Kohler, Yanmar, Cummins and Perkins.

The alternator, also known as the ‘genhead’, is the part of the generator that produces the electrical output from the mechanical input supplied by the engine.The modern-day generator works on the principle of electromagnetic induction discovered by Michael Faraday in 1831-32. The alternator contains an assembly of stationary and moving parts encased in a housing. The relative movement between the magnetic and electric fields inside the alternator generates electricity.

The other components of the generator like Fuel and Lubrication systems, Voltage Regulator, Cooling and Exhaust Systems and Control Panel etc. are all mounted together on the Main Assembly Frame to complete the generating system.

The Need for AV Mounts in Generators

Since the generator comprises of moving and electrical parts in its engine and alternator, it is pertinent that these 2 main components be mounted through Anti-Vibration mounts on the Main Assembly Frame. Generator vibration is caused unbalanced, electromagnetic or mechanical failure of the rotating part. Vibrations in gensets could be caused by imbalance of the rotor, the coupler, the coupling, or the transmission wheel (brake wheel). Electromagnetic causes like rotor core deformation caused by stator and rotor air gap unevenness causes the air gap flux to be unbalanced causing vibrations. When using a diesel generator set, many users might encounter abnormal noise and excessive vibration during the operation of the diesel engine. These vibrations cause damage to the equipment and create unsafe working conditions. Vibration isolation mounts protect generator and surrounding structures by reducing the amplitude and frequency of vibrational waves.

There are several factors that you need to keep in mind while deciding the AV mounts for your generator:
-> Technical Specifications: It's necessary to consult the engine and alternator manufacturer to obtain full technical operation specifications and engineering drawings.
-> Operating Location: Generators installed on roof-top of industrial buildings or housing complexes need to be free from vibration to avoid vibrations travelling through the building.

Why choose our Generator mounts

Egana has been providing Vibration Damping solutions for industrial machinery like generators, compressors, pumps and engines for more than 50 years. The main aim of using an Anti-Vibration mount in a generator is to reduce the amount of vibration that the machine transmits to the frame and the surrounding structure and buildings. EGANA's Anti Vibration mounts for generators provide the following advantages:

-> Natural Rubber Construction: Natural Rubber has the ability to accept and recover from extreme deformation of 200 percent or more. Our Rubber compound is formulated with the utmost precision to make sure that our rubber compound has longevity, resilience, resistant to high temperature variations and good ability to bond with metals. Another important characteristic of our rubber compound is it's ability to dissipate hear when it is subjected to continuous vibrational forces.
-> Superior Vulcanization Techniques: Our Anti-Vibration mounts are made by vulcanizing the specially formulated rubber compound at high temperature and pressure. The vulcanized rubber molecules so formed have higher polysulphidic crosslinks which are much stronger. This vulcanization technique has been perfected over the years with our final moulded rubber products which are far stronger, last longer and provide the highest possible vibration absorption.
-> Metallic Bottom and Top Dome: Our EGA series of generator mounts come with metallic plates on the top and bottom with a layer of rubber sandwiched in between to provide the vibration absorption. The metallic dome at the top prevents the rubber mounts from oil, water, dirt, ozone degradation and other harmful chemicals that the machine might be exposed to.
-> Fail-Safe Design: The EGA and EGA-MARINE series of Anti-vibration mounts are equipped with a metallic fail-safe. This fail-safe design ensures that the engine and the alternator are securely connected to the main assembly frame of the generator. This prevents the generator from toppling over while transportation or in mobile installations.
-> Versatile and Compact Design: Our generator mounts can be mounted on both external and internal generator frames. The compact design of the av-mounts provide easy fitting below the engine and alternator in the generator assembly. Our range of generator mounts are suitable for damping vibrations in generators weighing from 100 Kgs to 12,000 Kgs.
-> Premium Quality yet Economical: The generator mounts are manufactured in our highly efficient presses which churn out multiple mounts in a single run. This provides us the opportunity to provide our generator mounts with the highest quality yet in very economical prices. In most of the cases a complete set of our anti-vibration mounts for generators works out to less than 1% of the total cost but provides substantial advantages.
-> Product testing and quality certifications: We have extensive facilities and engineering resources to perform product, material and vibration damping tests under real-world conditions.

It’s important to keep in mind that picking the wrong Anti-Vibration mount for your generator could actually make vibration worse than if there were no mount at all. We recommend consulting with a vibration control expert early in the product design process when selecting the materials and mounts for any genset.

Power generators now a must for big buildings in Dubai

There have been recent regulations in Dubai that have made the installation of additional power generators in huge buildings and landmark projects a must for any contractor or company. These backup power generators need to be fully functional meeting all essential services including elevators and emergency lights. Real estate developers will be installing additional power generators at projects under their portfolio within UAE. With these generators being installed in residential/commercial locations, it is imperative that they do not produce excessive noise and vibration. According to the buildings department of Dubai Municipality (DM) there are close to 26,000 buildings under construction as of June 2017. With each building project, as per the regulations back-up generators need to be installed - hence there is huge demand for generators within UAE.

Egana has been supplying their anti-vibration mounts to reputed generator manufacturers in UAE and Middle East. With the highest focus on quality products providing maximum vibration isolation, Egana's EGA mounts have been the first choice for all generators manufacturers and generator canopy manufacturers in the MENA region.
