Case Study: Eliminating High Vibration Due to Natural Frequency Smith Pump Company recently was called to a pump station to solve a problem with high vibration on three 350 HP vertical turbine pumps. The pump station was fairly new and had only been in operation for a year or two. Two of the three pumps were operated on a variable frequency drive (VFD). The first step we performed in the field was a bump test. A bump test measures the unit’s natural frequency and is very important on a vertical turbine. The unit, mainly the vertical motor, will vibrate the most when it runs at its natural frequency. For example, if you measure the unit’s natural frequency to be 1800 cpm

December 2011

The year is almost over, and what a year it was. It is time to take stock in our past, and look toward the future.

Year 2011 will finish up being a record drought year in Texas. The year also was one of the hottest years on record. This was also a record year for Smith Pump in terms of revenue. Our fiscal year ended October 31, and the Company has roughly doubled sales volume in eight short years. Our current backlog isn’t at the level it was this time last year, but it isn’t bad. Not to worry, as our Sales Department will bring in enough business; in this I am confident.

Growing Up or How Far We Have Come

It wasn’t that long ago that Smith Pump only built a few small control panels for two horsepower grinder pumps. Back in early 2005, you had your choice of just one pump at one voltage and options included seal failure and horn. Of course you could get a control panel to run either one or two pumps. Wow, you could spend all day selecting options!

Since those days Granger Smith decided to go after more control panel business and rely less on sometimes unreliable control panel vendors. We have greater control over quality and schedule when we do things in- house . In addition, we have greater expertise to help our customers when problems crop up in the field . Our growth has been slow and steady, mastering one step before taking on another. This has proven to be a wise path.

Early on we recognized the necessity of becoming certified to build panels to UL508A specifications. Obtaining that certification opened many doors and showed that Smith Pump was serious about building quality control panels. At the same time we also did a LOT of work finding better parts for our panels. Those who were around back then can recall how the GE starters we used had high failure rates with lots of service calls but the starters we use today are nearly 100% perfect.

The Employee Of The Quarter is Larry Chandler. Larry’s supervisor, Neal McCaig had this to say about Larry... “Larry has been with Smith Pump for almost 18 years. He is leadman in the Smith Prime and light fab area of the fab shop. Larry is very dependable and an excellent worker. He is like a one-man band. He has many skill sets that we take advantage of. Larry has recently passed his ASME welder certification. Larry is very deserving of this award.” Congratulations Larry, and thanks for all the hard work. Enjoy your extra day off.

This year we spent much of our time trying to get things shipped that were sold the year before, a daunting task that remains unfinished. As an industry, why is it so hard for the pumping industry to ship their product on time? To answer would take too long for this article.

As I look forward to 2012, I can see us commissioning much of the equipment that shipped in 2011. There will be a fair share of startup problems, but our Service Department will resolve all the issues.

In 2012, Smith Pump will turn 50 years old. Quite a milestone, and one that deserves a little celebration.

They say we are in a 1st or 2nd year of a ten year drought. If that is so, how many of the state reservoirs will drop below the pump intakes next summer? There is a lot of preparation this coming year if it continues not to rain enough.

What is in store for Smith Pump in 2012? Well, we are not exactly sure, but...

... we turn 50, ... we plan to open a Houston branch in 2012, ... we will finish equipping the new repair shop in our Fort Worth branch in 2012, ... and, we will become ISO 9001 certified next year.

A busy year indeed, but one about which to worry next year. For now, it is time to enjoy the holiday season. So on behalf of all at Smith Pump, I wish you a Merry Christmas and a Happy New Year!

We here at Smith Pump continue to be impressed with the Liberty grinder pumps. With the patented “V-Slice® Technology and a new three-year out of the box warranty, Liberty has wowed employees and customers alike.

Albert Ruiz, Wastewater superintendent with Military Highway Supply Corporation related his experience with a Liberty grinder in a difficult school application. Located outside of Progresso, Texas, Albert had a competing grinder in the application that had to be pulled approximately once per week to be manually unclogged. Walter Williams, our South Texas Outside Sales representative in our McAllen, TX branch office recommended a Liberty Grinder pump as a solution. After the change-out, Albert reports that the Liberty has been running successfully without a clogging issue for over one year. In our Waco office, the Waco Cam-

eron Park Zoo’s American Bison Exhibit was another difficult pumping application. The American bison, some weighing in at over 2000 lbs, with hair so thick snow can land on their coat without melting, were causing problems for the maintenance crew at the Zoo. The tough hair from the buffalo along with sand and grit caused clogging issues for other grinder pumps in the bison wallow. Following Smith Pump Central Texas Outside Sales representative Chris Browder’s recommendation to change over to a Liberty grinder, the bison are happy

and the pump’s speed is 1800 rpm, you will have high vibration. To save time, we will only present the data for Pump #2. The bump test for Pump #2 meas- ured in line with discharge was 1500 cpm. Pump #2 operates on a VFD and has a full speed of 1800 rpm. The 1500 cpm corresponds to running the pump at 50 HZ. The owner of the pump station wanted to operate the pumps between 50 and 60 HZ. After performing the bump test, we ran the pumps and measured vibration. On Pump #2 at 50 HZ, we measured 0.47 in/sec rms at the top of the motor. To compare, the Hydraulic Institute allows 0.17 in/sec rms for vertical turbine pump of this size. We knew high vibration was caused by the natural frequency of the unit based on the bump test data. On vertical turbine pumps, you can move the natural frequency up and down by making modifications to the discharge head. These particular discharge heads were built very stiff with a total of eight 1” thick stiffeners on the outside of the head body and four 3⁄4” thick stiffeners on the inside of the head body.

Existing Discharge Head Solidworks Model of Existing Smith Pump modeled the discharge head in Solidworks. Since the measured natural frequency was 1500 cpm, and the pump operating range was 1500 to 1800 rpm, we wanted to lower the natural frequency below 1500 cpm. We knew by removing stiffeners from the discharge head we would lower the unit’s natural frequency. We removed stiffeners and ran a finite element analysis to determine how much we would lower the natural frequency. Our model study showed that by removing all the external stiffeners and half of all the internal stiffeners we would lower the natural frequency by 30%. Pump #2 was removed and its discharge head modified by removing stiffeners.

As the panel shop grew, our early panels were just modifications of previous panels. Slowly we added panels for larger horsepower pumps, more voltages, and options that include everything but a shoe shine station. Don’t laugh, compared to some of the options we’ve put in a control panel a shoe shine station isn’t that odd. Hmm, I’ll bet we’d have to make that shoe shine station in stainless steel...

Anyway, every year our capabilities grow. As this is being written, Smith Pump is building their largest pan- el. This bad boy runs two 125 hp pumps, includes soft starts, dozens of control relays, a PLC, UPS, MCPs, GFI outlet, custom ABS doors, all installed in a custom built stainless steel enclosure. Part of our greater capabilities was learning the meaning of this alphabet soup of letters. And it means we can do lots of impressive things we only dreamed about six years ago.

Solidworks Proposed Model Discharge Head Installed Stiffeners Removed

Pump #2 was put back into service with its modified discharge head and vibration testing was performed. The new bump test data gave a measurement of 86 cpm in line with discharge. The vibration measured at 50 HZ at the top of the motor was 0.05 in/sec rms. The vibration dropped from 0.47 to 0.05 in/sec rms.

In conclusion, determining a unit’s natural frequency is very important when designing a vertical turbine pump. Every fabricated steel discharge head that Smith Pump makes is modeled in Solidworks and goes through a finite element analysis to make sure the unit’s natural frequency (mainly discharge head and vertical motor) is 25% away from any running speeds. In this example, the discharge head (built by others) was too stiff and had a natural frequency at the pump operating speed causing high vibration. Since Pump #2 was so successful, we are currently modifying Pumps #1 and #3 the same way. Common sense tells us that the stiffer and stronger the discharge head the better, but this case study clearly shows us that is not the case!
