Présenté sur RTL Z - Le nouveau joint d'arbre CinchSeal NVB

En collaboration avec notre client Van Beek, Neocooper Industrial Solutions
a développé un nouveau joint à usage intensif pour les convoyeurs à vis.


Modèle en acier inoxydable CinchSeal NVBSS (à gauche), modèle en aluminium à revêtement dur NVBH (au milieu) et modèle en aluminium anodisé NVB (à droite)

Pour l'étanchéité des convoyeurs à vis ascendante pour les produits légers à très abrasifs, nous avons développé un nouveau joint, la série CinchSeal NVB pour des tailles d'arbre de 20 mm à 80 mm. Les joints ont toujours une plaque d'extrémité en acier inoxydable 304 résistant à l'usure qui est installée contre la bride de la machine et un boîtier en acier inoxydable 304 (à gauche), en aluminium à revêtement dur (au milieu) ou en aluminium anodisé (à droite).

Les joints sont équipés d'un élastomère large et résistant, qui a une plus grande surface de contact avec l'arbre et peut éventuellement être équipé d'un collier de serrage. Les deux larges coupelles de rotor robustes sont extrêmement robustes, résistantes à l'usure et offrent une plus grande surface d'étanchéité. Par conséquent, ces joints peuvent également être utilisés sur des convoyeurs à vis ascendants et partout où un joint est soumis à de lourdes charges.

Le logement et la disposition des trous sont adaptés aux roulements blocs carrés SKF standard, qui peuvent être montés directement contre le joint. Les boîtiers sont disponibles dans des tailles standard, mais une conception personnalisée est toujours possible. Un aperçu des données techniques se trouve au bas de la page.

Ces joints sont une solution idéale et éprouvée pour le transport ou le traitement de matériaux en vrac, de produits alimentaires (abrasifs), de produits chimiques, mais aussi de semi-solides, de boues et de liquides. Par exemple, nous avons déjà appliqué avec succès les trois modèles de joints NVB dans de nombreuses industries et avons ainsi pu augmenter la valeur de production de nombreux clients.

New Sealing System for Hot-Oil Applications

New Sealing System for Hot-Oil Applications

To eliminate vegetable oil and steam leaks in the production of snack foods, Neocooper Industrial Solutions has developed together with the seal manufacturer CinchSeal a brand new mechanical sealing system for drive shafts of frying processors, making the production of fried foods safer, more hygienic and more ecological as well as economical. The result of a three-year test and improvement period, the new CinchSeal NECAS seal is the solution for all “Hot Oil” applications in the food and process industry.

The core of the seal is a split elastomer made from AFLAS®, a new synthetic rubber that has all the benefits of Viton® but is also resistant to hot organic steams and vapours. The split AFLAS® elastomer is placed around the drive shaft and is glued together at the dovetail joint. It is secured with a hose clamp and rotates together with the drive shaft, protects the shaft against wear and prevents leakage along the shaft. The elastomer transfers the rotational movement onto two PTFE sealing discs, the Rotor Cups, which also rotate with the shaft. The PTFE Rotor Cups on the product and atmospheric side seal off against a stainless steel housing which creates an internal compression, thereby forming an internal and external sealing surface. The PTFE Rotor Cups and the housing are also split, so that no disassembly of the bearing and motor is required during installation.

This project has been started at an international snack foods manufacturer with an iconic crisps brand who was looking to replace the old packing seals, because the constant leakage burned the frying oil in the cord gaskets, causing smoke, odor and harmful substances such as trans fats and carbons. In addition, the cord gaskets caused wear and damaged the drive shafts, so they had to be metal sprayed after ten years in operation. This had been a time-consuming and expensive maintenance job for 13 shafts with a length of 2.5 meters and a diameter of 200 millimeters per processor line. The constant leakage also led to intensive cleaning and frequent bearing damage.

After an initial test phase of eight weeks with mechanical seals from different manufacturers, CinchSeal’s sealing system was the only solution that showed no leakage and the customer decided to cooperate with Neocooper Industrial Solutions to develop a seal model that would meet the specific requirements and a service life of at least 24 months. The seals could not be provided with a compressed air connection, usually necessary to support the compression in the seal housing, so a model with hose clamp was designed. The connection of the split PTFE Rotor Cups had to be reinforced in order to achieve the required service life with an operational process time of 4 times 6 months continuously, with one week for maintenance and cleaning in between. In addition, the standard silicone elastomer was found not to be sufficiently resistant to the hot organic steam and had to be replaced after 18 months. Therefore, after an intensive study of different rubber materials, a test with the new AFLAS elastomer was conducted and this was the breakthrough to meet all the customer's requirements.

The customer has since taken the decision to equip all six processor lines with the new CinchSeal NECAS seal and has mad this seal his Global Standard for all future production lines. The first processors have been retrofitted in 2021 and will continue to be upgraded during the next years.

Défis et innovations dans la production de cellules de batterie

Défis et innovations dans la production de cellules de batterie

When the Dutchman Sibrandus Stratingh developed the first electrically powered vehicle in the world in 1835, he could barely know that almost 200 years later his invention would become a world success. 45,000 fully electric and 94,000 plug-in hybrid cars are now driving on the roads in the Netherlands and this number is still growing sharply. This also means that the demand for batteries will increase further in the future and both the production volume and the efficiency will have to increase. A kilo battery can store a maximum of 150 watt hours (Wh) of energy, compared to 11,000 Wh per kilo of gasoline. But what are the main challenges in the production of batteries?

A battery cell consists of a cathode, an anode, a separator and the so-called electrolyte. The negative anode is usually graphite, but the positive cathode can consist of various metals such as Lithium, Nickel, Manganese, Cobalt and Aluminum. These metals are mixed in a certain proportion to each other and processed into a suspension with binder and additives. This suspension is poured under vacuum on a thin aluminum foil and, after drying, processed into battery cells.

No quality assessment can take place during the entire production process. Only after the battery cell has been completely assembled can the quality of a whole batch of cathodes be tested by discharging and recharging these cells with maximum voltage for several days. At the end of this cycle, the capacity, density, voltage drop and other quality factors are determined and the cells are assigned a category, from A to F. Only batteries of quality class A may be built into electric cars. If the batch does not meet the requirements, the manufacturer must use the cells at a loss for another application or they have to be destroyed, because there is no process to break up and reprocess once produced cells. Because a cost-effective concept for recycling batteries has not yet been developed, these are currently stored in large sheds.

E Auto Charging

The most important factor for the quality of a battery is the purity of the metal mixture. If foreign molecules enter the mixture during the production process of the suspension, for example from a seal that causes wear to the shaft, the quality will decrease and the batteries may become unusable. CinchSeal has developed the solution for this! A seal that does not cause any wear on the shaft and seals abrasive powders as well as suspensions for a long time, making the production of batteries much more efficient. As CinchSeals don’t require any maintenance work, use 30% less energy than other sealing systems and can even accommodate radial shaft runout and misalignment, the whole production process becomes more efficient, increasing long-term value.

The next major step in this sector is the introduction of solid-state cells, which do not have a liquid but a solid electrolyte and can therefore be produced much lighter and thinner. As a result, the capacity increases considerably and the safety of the cells will also make a major step forward.
