PUMPS

Pumps have been through the process design always overdimensioned in relation to the safety factor. At the time of the design, the exact operating conditions are unknown. 75% of alle pumps are minimum 20% to large (Fraunhofer Institute). Furthermore, there are often implemented process optimization after installation. Result is usually that the pump is not working in its optimum operating point. With Zytec coupling you can now easily optimise your pump immediately after commissioning.

Keeping pumps operating successfully for long periods of time requires careful pump design selection, proper installation, careful operation, the ability to observe changes in performance over time, and in the event of a failure, the capacity to thoroughly investigate the cause of the failure and take measures to prevent the problem from re-occurring. Pumps that have been: properly sized, are dynamically balanced, that sit on stable foundations with good shaft alignment, with proper lubrication, where operators start, run, and stop the machinery with care and where the maintenance personnel observe for unhealthy trends that begin to appear and act on them usually never experience a catastrophic failure.

This is true with a large percentage of pumping systems but, it is definitely not true with all of them. Frequently pumps are asked to operate way off their best efficiency point, or are perched on unstable baseplates, or run under moderate to severe misalignment conditions, or were lubricated at the factory and never see another drop until the bearings seize, and vibrate to the point where bolts come loose. When the unit finally stops pumping, new parts are thrown on the machine and the deterioration process starts again with no conjecture as to why the failure occurred.

Recently a supervisor at a pharmaceutical company who has been trained in root cause failure analysis stated that when a failure occurs on a piece of machinery it should be treated as a police crime scene where corrective action is not initiated until all the evidence is gathered by the scientific crime lab personnel to find the primary source of the malady. Until the real criminal is apprehended and banished, the crime is most likely to occur again and again. Take a moment to reflect on how many times you and your organization have thoroughly investigated a failure until you found the primary cause(s).

It becomes now possible to design a system preventing the cause of failure. With a magnetic coupling you can make your overall installation more robust and reliable.

FANS

Industrial fans take a significant share of total electricity consumption in the industry for their account. In addition, installations with fans are often subject to a high degree of vibration in the system. Maintenance or repair must be carried out regularly. Theses recurring cost are due to the nature of a fan installation. In ATEX environment, the cost of maintenance of fan installations increase rapidly and are often double to triple. Typically for fans are the high current peaks during the start of the installation. The non-contact magnetic coupling also provides a mechanical soft start preventing these current peaks. Often fans are indispensable in the production and cost of downtime can therefore be excessive.

In fan applications applying the magnetic coupling has many advantages. Significant energy savings could be achieved. In case of a mechanical error the damage to other equipment is prevented which reduces high costs for maintenance and repairs and avoids downtime. Applying the magnetic coupling means "FIT AND FORGET".

GENERATORS

Industrial gas or diesel generators are often used for temporary energy supply. This is usually in fail situations of the regular supply of energy. It is therefore of great importance that the temporary power is reliable, so that processes or climate control also are available.

In the maritime sector generators are used in driveline and for the basic energy supply. Reliable systems may even be more vital in this sector. Or generators are applied to the land or on the water, the characteristic of these systems is that the connection between the motor and the generator has a high degree of mobility. Alignment errors of the couplings can simply not be avoided. This results in vibrations that can cause damage to all other components in the system. The magnetic coupling isolate the components and eliminates the vibrations. The contactless connection is the easy solution to achieve this. Vibrations by misalignment, torsional vibration, or other kind of vibrations are not passed on to other components in the system by applying a magnetic coupling. This will prevent downtime and reduce maintenance and repair. The reliability of the entire system will increase.

COMPRESSORS

Industrial compressors have a high start/stop frequency and are often utilized with an VFD. At the start the installation experiences high loads and a electronically controlled soft start is applied. A compressor has jolting components in the system. A constant correct alignment of the stationary coupling assembly is of great importance. Reliability and thus a high degree of available compressed air needs on the other hand during operation to be very high. Downtime needs to be prevented because of the immidiately resulut in lack of compressed air. With the current fixed couplings and control systems it is not easy to ensure continious available air. Failing couplings, damage to components from vibration, space limited electronic speed control, electrical fault, remain a constant subject of inspection and maintenance.

The contact-free magnetic coupling can improve the reliability of a compressed air system to a large extent. Whether you chose for an VFD combined with an F-TORQ or whether you chode for a speed-regulating V-TORQ, you always chose for longer service life of many components in the system, increased MTBF (Mean Time Between Failure) and lower frequency inspection and maintenance. Therefore lower operating costs.

CONVEYOR BELTS

Conveyor systems often have varying loads and high peak loads at starting or stalling. This causes excessive wear or elongation of the conveyor belt which as a result, a lot of maintenance and downtime. Long conveyor belts such as in ports or mining are hundreds of meters or even several kilometers long. In order to prevent a rack in the loaded start band, multiple actuators may be used. Fluid couplings are used, inter alia, in order to divide the driving power equal between the motors. The fluid coupling is used exclusively to mitigate the run electrically and mechanically. Each fluid coupling is combined with (a V-belt transmission or) a flexible coupling. The alignment of this is even more difficult if no fluid coupling because of the greater length of such a coupling combination.

Where normal misalignment though inevitable (given the size of the sector alignment, training other technologies, expertise, photographic equipment, -Studies), the vibrations are caused by the same flexible couplings on the end of a fluid coupling even greater. To a lesser degree can also be in a case of transportation systems that are used in the packaging industry or packet processing. The actuators must be perfectly aligned and balanced to additional but not to contribute to the many harmful vibrations. As a full-rate production line comes to a standstill, there is a very high starting currents when the tape is put back into operation. Here, it often happens that the fluid reaches such a high temperature in the couplings which escapes the liquid via the safety of the coupling. This may cause a dangerous situation for bystanders. It also involves high costs of cleaning of the immediate vicinity of the coupling, refilling and downtime along with it.

The contact-free magnetic coupling is an excellent alternative to (liquid) couplings in such systems, without all the disadvantageous properties as described above. Vibration and therefore sound, and damages are prevented to a significant extent. Unsafe situations by escaping hot oil are history. Shock loads are absorbed by the magnetic coupling and a "soft" start is guaranteed.
