Performance increasing upgrade solutions for suction rolls
Wear detection for all suction rolls: SealView
How can we help you?
Total utilization of the seal strip capacity due to exact wear detection.
The reliable SealView technology, which can be used with conventional and HydroSeal seal strips, records the wear progress of each individual seal strip. The system informs the operator and our service staff about the current status and the expected remaining service life of the seal strip and draws their attention to a necessary roll change in time.
The system is based on a non-electrical system, which makes it highly reliable. Once SealView is completely installed in a suction roll during roll servicing and put into operation by our service staff at the operator's site, the wear of each individual strip can be visualized on a monitor in the control room.
The system warns the operator when half of the seal strip service life is reached. If a safety reserve is reached before the end of the complete wear area, an alarm is triggered. With this information, the operator has enough time to plan a stress-free removal of the roll and to coordinate further steps of the roll service as well as the procurement of replacement strips with the Voith Service Center.
The system reveals its full potential especially when roll running times are extended beyond the usual period of time. By displaying the wear of the seal strips, the operator knows that he is safe even with extended operating times, without the worry of an unplanned standstill.
- Total utilization of the seal strip capacity
- Longer running time of the suction rolls
- No unscheduled shutdowns
- Planning time for spare parts procurement
Excellent savings in lubrication water consumption
HydroSeal is the first to provide the option of dispensing with the conventional lubricating shower regardless of the type of suction roll or manufacturer.
Thanks to HydroSeal, the lubricating water is distributed continuously over the entire width of the seal strip, which allows the surface to be continuously covered with a homogeneous film of lubricating water. The efficient feed substantially reduces the amount of lubricating water required. Moreover, this new design prevents remoistening of the paper web and also improves the CD moisture profile.
Trials carried out in the field on our customers' machines demonstrated that, by using HydroSeal, lubricating water consumption could be reduced by up to 87%. Specific energy consumption was cut by 9%. This means that even on just one suction roll, HydroSeal can achieve savings of 100,000 euros or more per year, offering a distinct economic benefit as well as an ecological advantage.
