Vibration measurement, training and installation of fixed measuring points
We have received another handheld vibration meter for condition-based maintenance + software for data collection and analysis. This time for Samsø Rederi aboard M/F Prinsesse Isabella.
In collaboration with Chief Engineer Allan Daugaard Jensen, we have drawn up and installed a complete measurement route on the ship, so that they can now monitor their rotating equipment on board. The instrument automatically indicates on the route where the next measurement point is to be taken. TME measuring chips are installed at the measurement points, ensuring good measurement surfaces and enabling the measurements to be repeated with great accuracy.
As the four engine room fans are not easily accessible, we had to install fixed vibration sensors on the electric motors and run a cable to a secure box so that the plug from the data collector could simply be inserted into the box and the values measured inside the fan.
Balancing and condition monitoring
Can you test a plaster mill for imbalance and vibrations? That was the request we received on Thursday morning from Hans Jakobsen, foreman at the KNAUF plaster factory in Hobro. Within an hour, we drove down to the factory to examine the equipment in question.
After visual inspection while the mill was in operation, we agreed that the mill should be tested the following day. The vibration measurements left no doubt that there was an imbalance in the system. We had to balance the system over the weekend.
The hammers mounted inside the mill had been removed to test whether it was the mill wheel itself, on which the hammers were mounted, that had become unbalanced. A test was carried out on the plant without hammers, and the plant was found to be in perfect balance, so it was ruled out that this was the cause of the imbalance.
It turned out that the hammers that were installed did not comply with the correct tolerances and were worn unevenly, so it was decided to install new, precisely balanced hammers and measure the system again. The imbalance in the measurements was low, and we also performed a bearing analysis on the bearings, but no damage had occurred.
Classification and reporting of generator sets according to ISO 10816-6
Nordhavn A/S supplies, among other things, engine/generator sets to the maritime industry. In connection with a delivery, it was a customer requirement that the delivery should include an ISO 10816-6 report and classification number for the new generator sets. Nordhavn A/S has laboratory facilities for testing engines on new generator sets, which meant that we could also come and carry out vibration measurements at different loads in accordance with the standard's regulations.
We then analysed the measurements and compiled them into a comprehensive report, in which we provided a detailed report with the vibration classification number of the generator set based on all the measurements.
Troubleshooting and condition monitoring
The main motor on a Koenig & Bauer printing press had been reported by the operator as making an unusual noise, so TME solutions ApS was asked to locate the cause of the noise and perform a condition check.
Before visiting the customer, Koenig & Bauer A/S sent us data sheets on the engine so that we could do some preparatory work before arriving on site. Important bearing frequencies, etc. and ISO standards were programmed into our measuring instruments, and the best measuring points on the engine frame were located according to the position of the bearings on the sectional drawing.
The measurements showed that there were very serious bearing faults on both main bearings, after which we sent a report recommending that the engine be serviced immediately in order to avoid a breakdown.
The NDE bearing was damaged and was replaced, after which the engine was able to continue running.
