With the substantial promo progressively for Slip Ring applications, the need for slip ring has actually additionally been included various applications a good deal, which has more strict criterion for technical requirements. slip ring is made of brush and also blades generally, it can beam and also power device between fixed part and also turning component under any turning condition for different of devices.
No doubt, mercury slip ring, just benefit from mercury as a transmission media for slip ring assembly. Mercury is the just one liquid steel can work under typical temperature status, this design creation could come true as a result of its function and metal transmission. Mercury slip ring just secure mercury in the within slip ring, which combines with set part as well as turning component with each other and also use mercury to transfer current/signal without noise and also high accuracy or dependability while running. As a result, the structure of mercury slip ring is not made complex contrasted various other types of mechanical slip rings. From the measurement, its dimension is smaller sized a great deal compared to mechanical one, this is among the most significant advantage. The turning of mercury slip ring is mostly for the friction amongst inside mercury molecules and also sealed components. So mercury slip ring has the highlight of lesser wearings, longer life time, higher functioning speed and also maintenance cost-free.
Nevertheless, mercury slip rings additionally has some negative aspects, because of the big thermal development coefficient of mercury, then it could not run in the high temperature. Generally, the temperature level can not exceed 60 centigrade. Secondly, the expense is pricey as a result of high accuracy and also mechanical closed framework. On the other hand, Mercury Slip Ring has strict need for workplace and shock condition, otherwise, it needs to affect the life time substantially.
Nowadays, there is around 10 percent of wind turbine slip ring is fiber brush contact materials on the market, this kind of slip ring only have to keep hardly ever. One more 60 percent of slip ring part is made from composite steel brush as well as generally it combines with metal as well as graphite. Also if this kind could satisfy around 75 million rotations service life time that several of suppliers stated, but its additionally need maintenance regularly. The recurring 30 percent wind turbine slip ring embrace solitary rare-earth element brush, usually talking, the performance of fiber brush is better compared to over 2 of types.
The primary reason is for: composite steel brush design can use brush ahead of time to prevent slip ring attrition, likewise it requires long brush just might postpone brush exchanging circle in the best constraints. This kind of products will fulfill 3 obstacles generally in the large power or high reliability slip ring application.
Solitary steel brush compared to composite brush style, the biggest benefit is that residues is minimal as well as greater ability for signal circuits. Yet, single metal brush style likewise exist some drawbacks:
1. Single brush will certainly lead to restricted current-carrying for smaller sized dimension.
2. As an example, the majority of materials between gold and also gold needs lubrication, it is very tough to keep adequate lubrication constantly.
We trust that there will certainly be increasingly more slip ring needs in wind turbine application in the near future, wish completion user could choose dependable as well as finest slip ring producer to provide company and also layout an appropriate slip ring option for you.
