The Firmware 5.0 update helps to boost efficiency and allows maintenance technicians to scan large areas quickly and visually pinpoint technical issues before they become critical.
To help users identify and localise ‘mechanical areas of interest’ within short timeframes, COMTEST, a local representative of Fluke – a global technology leader in the manufacture of compact, professional electronic test and measurement tools and software – has added a unique new feature to the ii910 precision acoustic imagers. The Firmware 5.0 update brings a MecQ facility to the ii910, which helps minimise unplanned downtime and cut repair costs by enabling early identification of potential mechanical problems. Energy savings are also achieved by carrying out repairs early and reducing faults.
The update was developed following extensive research involving Fluke customers worldwide. Maintenance specialists and technicians said their crucial focus was identifying issues on the potential failure curve as early as possible.
Looking at various types of conveyor systems, the research showed that non-driven bearings are often the root cause of many mechanical faults. Because these systems are integral to the overall production process, lengthy downtime could significantly impact the factory and cause significant issues along the supply chain. This applies in food and beverage production as much as it does in the logistics, electronics, automotive and mining/raw materials sectors.
Never inspected
Despite a line going down representing a huge concern (and costing anything up to R2,430,000 an hour), Fluke found that around 59% of conveyor belt systems are never inspected. In comparison, another 11% are checked manually. The research showed that human sensing was the least effective way of detecting a problem, followed by contact temperature and thermography. Testing using contact vibration or airborne ultrasound also represented a challenge – with ease of use being a significant issue with the latter – but acoustic imaging offered the most effective method.
Not only did customers say that the ability to localise issues was vital if substantial cost savings were to be achieved, but they also needed a scalable solution that could help those with lengthy conveyor systems (a significant warehouse could operate up to 80km of conveyor belts) or where accessibility was an issue (perhaps because of conveyor guards).
Using the Fluke ii910 acoustic imager with MecQ, the process of carrying out non-contact inspection on conveyor systems is simplified considerably, with the unit immediately identifying the locality of a mechanical area of interest through sound pattern comparison. Once the issue is displayed on-screen, the maintenance professional can note it, share it with their team and address it on their maintenance schedule.
User-selectable frequencies
MecQ was developed to bring an extra layer of detection to the ii910 in addition to taking a picture, taking a video, carrying out leak detection with LeakQ, and detecting partial discharge in PDQ mode.
Although the most common frequency for ultrasound instruments is 30kHz, the ii910 with MecQ now offers user-selectable frequencies from 2kHz to 100kHz and fixed multi-mode frequency bands of 15kHz, 20kHz, 30kHz, 40kHz and 60kHz to check various stages of bearing deterioration. The user can choose whether to turn these pre-set frequency bands on or off, depending on the environment.
Tako Feron of Fluke says: “Any member of a maintenance team will love the ease-of-use the new MecQ facility provides with its intuitive interface and seamless integration with existing leak and partial discharge detection tools. They will also appreciate the ability to boost efficiency, maximise uptime (by reducing meantime-to-repair) and lower costs while ensuring high safety levels through contactless inspection and eliminating hazardous situations. Thanks to MecQ, the ii910 now enables maintenance engineers to locate a problem, annotate a screenshot, share that with the team and then schedule repairs during planned downtime. Having all these workflow enablement solutions built into a single tool is unique to Fluke. The Firmware 5.0 upgrade has also simplified what could ordinarily be a highly complex and time-consuming inspection and maintenance operation.”
Feron adds: “It is important to remember that the ii910 with MecQ is designed to offer a first-line scanning solution that identifies an area of interest at scale for a follow-up inspection.”
