Registered Member Dave, We use the skf tked1 to check for electrical discharge It registered about 49000 pulses in a minute. This is approx 5 times more than other motors tested. This Bearing was checked and installed properly. Just sent out a sample to see the condition of the oil. This motor and bearing isn’t 2 weeks old. Thanks for the info, Keith [ more ]

key performance indicators
Registered Member One thing to look at depending on the number of machines you have in the program is the percentage that meet or exceed the recommended ISO cleanliness code. That is not only a good start on oil condition but also shows how you treat your machines-are they kept clean and water free, do you have good breathers installed and are you filtering any top off oil. There are also the sampling indicators-% on time; % missed; number of resamples required per year due to inadequate sampling locations or... [ more ]

Registered Member We have a number of these types of machines installed on our site and found similar problems, although not as severe as this and normally only after 4 years operation. API672 refers to a FZG load stage of 5, but we have found that a FZG load stage greater than 8 is much better. There are tremendous forces generated between the bull gear and the pinion teeth which compress the oil film, this pressure converts to heat energy and if the oil film is not strong enough to withstand these forces...

Electric Motor Bearing Grease - quantity and frequency
Registered Member Hi There, Depending on the calculation used the returned "interval" may be the L10 or L1 life of the grease. This means by going longer than the calculated relive interval, there is a 10% or 1% chance the grease will fail. There are a lot of other factors at play here, and some calculators have a bit more fat built in, i.e some will give an interval of 1/3rd the "grease life". Grease thickener will have an impact also. Most relube calculators will assume a basic lithium soap/mineral oil but... [ more ]

Oil Storage and Use
Registered Member Tagging lubricants for date of receipt is good practice, but you may also want to investigate how to decipher the coding on the drums which may provide information on the date of manufacture as well. Sometimes, lubricants can reside at a local distributor for many months before you receive it at the plant, and often in less than ideal storage conditions. In addition to tagging the drum with date of manufacture and/or date of receipt, consider a color and shape code schema. The color and... [ more ]
Registered Member Drums should be identified with the receipt date when they are received and then put into inventory - to make it easier to pick the FIFO drum inventory should be rotated so that the FIFO drum is the first item to choose - one other possibility would be to place drums in racks so that again it is easy to identify the oldest product drum there [ more ]

Difference between pore blockage and laser test for particle count.
Registered Member Pore blockage method will always yield better ISO numbers than laser method unless you ask the lab to pre treat the sample by agitate/deaerate the sample before putting through laser. I was dealing with a situation where "before filter" sample had a better ISO # than after filter sample. It just didn't make sense. Then I found out about pore blockage method and found a new lab to perform using this method. Samples came back the way its suppose then. [ more ]
Registered Member Very good. Thanks. [ more ]
Registered Member The methodologies are different so the "accuracy" cannot be compared. The laser or any optical based particle count will include everything that blocks the signal-wear particles, water, varnish etc. The pore blockage only counts the captured particles. In gas turbine LOA where varnish is an ongoing issue I always run both-if there is a big difference between the 2 (> 3 or 4 ISO codes) I know I have something in the oil that needs to be investigated. Take a look at the ASTM test codes and... [ more ]

Pressure relief grease zerks and drain plugs
Registered Member I am interested in this topic, as well. Our factory has a number of applications where it is very difficult to get to the grease drain plug to remove with the equipment running. I would like to be able to grease these motors during the shift with Ultrasound. I was thinking that it may be a good idea to install these relief zerks in new greasable motors with no means of relief built into the design. We would only install these zerks in new motors or in motors that have been observed to... [ more ]
Registered Member Overall, are they worth the change? Do they perform as described below? The pressure relief drain valve would eliminate the need to remove the drain plug and run the motor for 20 minutes. That's a nice labor savings if you could just start up and turn the equipment back over. The pressure relief grease zerk would help eliminate the possibility of over-greasing the bearing, thereby reducing failures. [ more ]

Modified ASTM D2272 RPVOT Test
Registered Member We use the RPVOT test on our steam turbine lub oils but only because I have to due to some archaic site requirements. I have found with back to back testing that RULER and MPC tests to be far more reliable and give more linear results (confirmed via lab testing of all three on a sample of oil to which was added increasing quantities of fresh oil). RPVOT is to me a test used by lub manufacturers to sell you oil and they will often quote very high numbers for their oils as some kind of... [ more ]

trafo oil
Registered Member I agree with everything rgf12 wrote, as usual. To add a little (trying to guess what might be the question) Different tests are done on transformer oils than lube oils. It may be sent to a different lab. Often the plant people assigned to monitor/trend transformer oil results are different than the people assigned to monitor/trend lube oil (depends on the plant). If you replace radiator without draining main tank, think carefully about whether your flapper valves will hold. If you replace... [ more ]
Registered Member What are you talking about here? Is this a transformer? When you post a question please include all the information you have-a detailed description of the equipment in question, model number, oil type and quantity, age etc. You can get a good deal of help and advice here but you need to provide some details on what you need or most readers will ignore your postings.

What to call a condition directed oil change
Registered Member Agree that the initial task to get the oil sampling would be considered part of a PM but the oil change based on the results would be a corrective measure. PM tasks are what would be applied to all similar assets in the portfolio and you would not change oil for all assets, only an oil analysis. [ more ]
Registered Member To the original question as to what the follow up work should be coded - I certainly believe that the initial oil sampling work order would be a PM or PdM (preventive or predictive) and the follow up for an oil change would be a CM (corrective) as the condition no longer warrants further use. We have created in our CMMS work order system a code called a CPM (corrective from a PM) which helps us understand how effective our PM work orders are in finding abnormal conditions. [ more ]
Registered Member I would say yes. Rarely have I see an OEM tell me what preservative oil they used and if that is the same as the recommended oil. I wouldn't want to use an oil that has sat in a machine during storage without knowing the details of the lubricant and it's condition. Too much opportunity for water or particulate contamination. Drain/flush and start fresh. Don't forget to baseline the new oil with your lab. [ more ]

Steam Turbine Hydrauluc Oil Problem
Registered Member A little background please-what is the specific oil type-MFG/ISO Grade? Age of oil? Duty cycle? Is this a peaking or baseload unit? The reason I ask is that different lubricants used as hydraulic fluid in turbines have different acceptance criteria and different mitigating actions. [ more ]
Registered Member Filter elements never chocked in history. Lube oil is different. See Lube oil report attached. [ more ]
Registered Member I'm not sure but the report shows very high water content (926 ppm). Is the oil used also to lubricate the turbine's bearing? Look at the system on the site to find a low drain point. You may remove a large deal of the water by draining the accomulated water from low points. In my previous post, i suggested to replace the filter elements not the conditioner as a whole. Regards- Ali M. Al-Shurafa [ more ]

High bearing Wear Particles in a new bearing
Registered Member I overlooked that this is a slow-speed application 17rpm. I don't have any machines like that, but I understand bearing defects are a lot harder to see in vibration for those applications. Others can contribute better about how best to detect bearing defects on slow speed bearings. I gather maybe you've had several bearing problems and in the past they were detectable both by grease sampling and vibration. Now upon installing a new bearing it shows similar symptoms by grease and not... [ more ]
Registered Member Hi RGF, Grease is directly supplied from the grease barrel with 55 pulse per minute.Cage is of steel. As per my previous experience,when ever we opened the bearing the outer race was having heavy scoring and it gets cracked after opening. Hi E'pete, total wear particle concentration is 497.(limit 100). PLP is 30%. I think for grease also same procedure is followed as oil.Please find the attached spectrum of the roller brg. RPM=16.8.Bearing= KRW 12.70.01 four row cylindrical roller bearing. [ more ]
Registered Member Now that I think about it a 700 micron particle is huge in the oil contamination world. I would think that it maybe a sampling thing. In my experience its tough to get a good grease sample from a bearing unless it is laying on the shop bench. The grease tests basically wash the carrier from the grease (lithium/calcium etc.) and test the base oil. Rich Wurzbach from MRG is the grease testing guru. http://www.mrgcorp.com/index.html [ more ]

potential varnish test
Registered Member What is the age and type of oil? We use a range of test methods to assess varnish potential/oxidation in our steam turbine oils to include MPC, RULER, RPVOT, Total Acid, FTIR. In line with what Pete has said I think you need to establish the state of your bulk oil. This will help to ascertain whether it is local (to the bearing) conditions that are leading to the varnish or whether is is down to degradation of your entire oil charge. I would assess RULER values against a new sample to gain... [ more ]
Registered Member Good responses rgf… sounds like he has fought varnish a lot (more than me). We have a lot of variability in particle count (optical method). I hadn't thought about the different counting techniques and what they might tell us. Testoil has some good info on varnish testing here: http://testoil.com/knowledge-center/reference-guides/ What they say about the two methods, similar to rgf's comments: "Particulate contamination is tested using two methods optical and pore blockage. Optical particle... [ more ]
Registered Member Pore blockage is when they force a portion of fluid thru a paper wafer that is of a known mesh. It captures mainly foreign material in the oil such as dirt or wear particles. Any soluble contaminants will pass thru the filter (depending on size) and won't be counted. The optical method counts anything that blocks the signal, either solid material of "soft contaminates" such as water or the byproducts of varnish. Check with your lab and they can tell you which method they use. If they have an... [ more ]

centrifugal compressor lube oil pump
Registered Member Have you collected data at Vertical and axial direction on NDE and DE. It does not seems to be a flow related issue based on the spectral data. What about the process parameters- is there any differential pressure indication across the suction strainer. Is this a long term issue or happened after any shutdown/maintenance [ more ]
Registered Member I may be wrong, but what I see is a 1XRPM that is not reflecting an Unbalance. Rather the 1XRPM is an indication of a support bracket becoming loose.

pump Oil change before commissioning
Registered Member This post may be a little late in the game. I believe most corrosion/liquid phase inhibitors are a 32 Vg. Typically this is 10% addition or less, it would seem just the viscosity alone would justify an oil change prior to commissioning a unit due to trending oil analysis.

Temperature and Oil Viscosity
Registered Member Agree , when oil temperature rises high it oxidizes , it is the additives that most deteriorate and produce solids ( varnish ) . These highly raise viscosity . Have seen this many times in case of aluminium rolling mill , finishing or foil , high speed , hence high temp. Every after chock removal and disassembly there is lot of dark brown varnish in the sump. BP guys after analysis say for additives burn off. So , need be careful for oil choice , especially synthetic ( PAO ? ) with special... [ more ]
Registered Member What you and Gary state are both true. Most oils will not begin to oxidize until they reach a temperature of around 200 degrees F, less than the oxidation point the viscosity will change with temperature. Most oils have an temperature vs. viscosity curve available either from the oil company or somewhere on the web. [ more ]
Registered Member Overheating causes thermal failure of the oil i.e. oxidation and it is this which leads to viscosity increase. The oil becomes loaded with insolubles (varnish). Gary [ more ]

Oil leak due to high underpressure in building
