Oil analysis and vibration analysis make a great tag team when it comes to assessing rotating equipment condition. Even if oil analysis trending is carried out by itself it still can be a powerful tools assessing whether or not there may be trouble coming down the pike – rolling element bearings, gears and other key components leave key evidence of them failing behind in the lubricant. Depending on your plant size and usage of lubricant, quite a few lubricant suppliers also offer free oil analysis. While that seems great at the first glance, there are quite a few wrinkles that can lead straight to catastrophes that the analysis was supposed to help prevent. I will review a few issues and elaborate on what an analysis report should cover in the course of this blog.
Aerzen USA insights and guidance for blower, compressor and vacuum pump applications
Trending is the key to success with precision maintenance. At Aerzen USA we make good use of state of the art condition monitoring devices that fit any budget. From low cost vibration sensor based switches to full blown online monitoring systems ranging from IFM Efector's VKS, Octavis and Multiplex devices we have the trending system that will fit anyone's budget.
There are many solutions that can help avert such issues. One effective one comes from the Lean Manufacturing program called 5S in which - among other important aspects - lets you sort and mark all items you need to do your job with. This is perfect for lubricants. Visual signals such as color coding bins, drums and cans and using the same colors on markings on the actual equipment will make anyone's life a lot easier and also help you reach the maximum service life of your equipment.
Oil-free compressors are most often used in process gas applications. Hazardous, poisonous or simply dangerous gases are usually being compressed and conveyed by our screw compressors. It is critical therefore, that such conveying media be sealed against leaks to the atmosphere or, in the case of gases incompatible with lubrication oils, against leaks into the compressor's lubrication system. Dry gas sealing systems are often applied for such tasks.

The refinery flare gas can be considered one of the most challenging, but it can be handled with the right compressor.

Performance - Only buy Aerzen's blower packages... just kidding, but there is a serious point here. Any manufacturer's claims of performance need to be verified to insure the correct amount of pressure will be generated for the application. Insist on knowing the performance and efficiencies (power requirements) of the complete blower package you buy not just the performance of the bare stage. An undersized drive motor will limit performance.
Is the blower sized for the correct amount of air? Too much air will lead to higher pressure drops and increased power consumption. Too little air will result in line plugging.
- Is the blower and motor sized with enough safety to overcome upset conditions?
- When comparing blowers from various manufacturers, did you look at:
- Maintenance requirements
- If you are conveying food products, you also want to make sure that no particles of the silencer absorption material and no lubrication oil can enter the compressed air stream and thus mix with the conveyed product.
