KONE approves NAPL new facility at SIPCOT Industrial Park, Vallam

KONE, the 100-year-old lift manufacturing company approved the new facility of NAPL at SIPCOT Industrial Estate, Vallam Vadagal, Kanchipuram.  An extensive assessment of the new facility was conducted by KONE and was satisfied with the new facility’s plant, machinery, lab, and other infrastructure.  All KONE requirements were met by NAPL satisfactorily.  The physical assessment was carried out on video call due to CoVID19 Pandemic.

FUJITEC approves NAPL’s new facility at SIPCOT Industrial Park, Vallam

After an extensive assessment of the new facility of NAPL at SIPCOT Industrial Estate, Vallam Vadagal Village, Kanchipuram District, Tamil Nadu, the Japanese major FUJITEC approved the new NAPL facility at SIPCOT Industrial Park for manufacturing the anti-vibration components for its requirements.  NAPL manufactures components for FUJITEC Elevators.

NAPL Moves to Brand New Facility at SIPCOT Vallam, Kanchipuram, Tamil Nadu

NAPL has moved its manufacturing operations to a brand new facility at SIPCOT Industrial Park, Vallam Vadagal Village in Sriperumbudur Taluk, Kanchipuram District, Tamil Nadu.  This facility will exclusively manufacture NAPL’s range of anti-vibration products.

This facility is spread over 5000 Square Meters.  Currently, 1000 Square Meters are covered for the existing production requirements and the balance is available for future expansion needs.  The facility is located in the well-known SIPCOT Industrial Park and is approachable easily from Chennai.

Although we had planned for a grand inauguration of the facility, the CoVID19 Pandemic came in the way.  However, we will have a ceremony and celebration once the Pandemic fades away with our existing and potential customers, suppliers, and other key stakeholders.

In a dynamically changing world of technological advancement, we are inherently aware that we need to be at the cutting edge of technology and R&D. NAPL was founded and is operating on the principles of application-oriented product range, high-quality products as well as dedication to innovation and individual solutions. We have a strong bias towards technology which has helped us to become a 100 products company within a short span of time.

Rubber has been used in vibration isolation for a considerable time

All engines and many other mechanical and electrical devices require mounting and restraining. These mounting systems often have the added function of isolating the machine vibrations from the mountings.

If we now consider a typical system where we have a vibrating body attached to a bed via a rubber mounting system we have 3 units to consider:

1. The vibrating body, the freer this is to move the more the vibration energy will be dissipated away from the source of the vibration. This will reduce one cause of damage and prolong the life of the equipment. To allow for this vibration we need the mounts to be as soft as possible.

2. The bed and fixings are isolated from the vibrations by an elastic mounting system which prevents transmission of the vibrations to the bed. This reduces the fatigue of the fixings and stops any distress caused by the transmitted vibration. Again the softer the mount the lower the amount of vibration energy transmitted.

3. The rubber mounting system should be capable of carrying the weight of the equipment mounted on it, along with any other loads applied as a result of the equipment’s operation. It must also isolate the vibrations from the bed. The mounting system should also have a long life. For a long life we need strains to be as low as possible, and therefore the stiffness as high as practical.

When considering the above requirements there is a requirement for the mount to be soft and hard at the same time. This requirement to compromise poses a significant challenge to the mount designer to reduce the strain on the rubber at the applied loads, and on the manufacturer to make the mount to the highest standards to extend the life. These considerations require a significant understanding of both vibration engineering and rubber.

Vibration isolation theory is well documented, however, real solutions are complicated by the difficulty in defining and measuring the relevant properties of the rubber. Also as can be seen from the schematic wind generator drive chain the complex interactions require skilled analysis.

IMPORT SUBSTITUTION ENGINEERING FOR VESTAS WIND TURBINES

• The MAKE IN INDIA Experience

Vestas is the energy industry’s global partner in sustainable energy solutions. They design, manufacture, install, and service wind turbines across the globe, and with +136 GW of wind turbines in 84 countries, they have installed more wind power than anyone else.

Through their industry-leading smart data capabilities and +117 GW of wind turbines under service, they use data to interpret, forecast, and exploit wind resources and deliver best-in-class wind power solutions.  

One of the core objections to wind power has been the amount of vibration and noise they create.  So when Vestas approached NAPL for indigenizing some of the anti-vibration components as a substitute for imported components as per the Government of India’s vision of MAKE IN INDIA, it came as no surprise.

But the job was very difficult.  One on hand, NAPL had to meet the global Vestas standards.  On the other hand, the components had to be completely MADE IN INDIA.

Working with the Global Technology Team of Vestas, NAPL embarked on the journey.  Today, Vestas India is an OEM customer for NAPL for several parts including anti Vibration components.  After the parent organization of NAPL, NUTECH INDUSTRIAL PARTS has a stated position – ANYTHING EVERYTHING FOR WIND PARTS.
