Why You Should Include Oil Analysis in Your Preventative Maintenance Program

By Dustin Flynn on Thu, Jan. 04, 2018

Accessing a System that is Currently in Place

Preventative maintenance is a program put in place in most manufacturing or production industries to ensure quality scheduled maintenance is provided. Maintenance professionals implement these routine inspections before, during and after the operation of machinery. Parts of this routine can include areas that can only be inspected by touch, not sight, to determine what is happening under the surface. 

Oil analysis can be added to this routine maintenance to give a fuller picture of whats happening inside machinery and equipment. By including oil analysis in a preventative maintenance program, maintenance professionals are provided with detailed inside information that could prevent issues in the future, like unexpected downtime.

DFE: Testing Filters Under Real-Life Conditions (Part 4 of 4)

By Jim Harlan on Tue, Jul. 18, 2017

Throughout the first three entries in this series (find parts one, two and three), we've discussed the difference in two filter element testing methods, ISO16889 and DFE. We've also illustrated how many elements fall short of their stated beta ratio under dynamic flow conditions. Today we'll wrap it up with simulated cold-start tests.

DFE Multi-Pass: Cold Start Contamination Retention

Once the element has captured enough contaminant to reach approximately 90% of the terminal ΔP (dirty filter indicator setting), the main flow goes to zero and the injection system is turned off for a short dwell period. Then the main flow goes to maximum element rated flow accompanied by real-time particle count to measure retention efficiency of the contaminant loaded element. The dynamic duty cycle is repeated to further monitor the retention efficiency of the filter element after a restart.

DFE: Testing Filters Under Real-Life Conditions (Part 2 of 4)

By Jim Harlan on Tue, Jun. 27, 2017

Last week, in part one, we briefly discussed how filter elements are rated by manufacturers. This week we're discussing the industry standard ISO16889 multi-pass test and Hy-Pro's standard, the DFE test. (Already read part two? Read parts three and four.)

Current Filter Performance Testing Methods

To understand the need for DFE, it is important to understand how filters are currently tested and validated. Manufacturers use the industry standard ISO16889 multi-pass test to rate filter efficiency and dirt-holding capacity of filter elements under ideal lab conditions.

Figure 1 depicts the test circuit where hydraulic fluid is circulated at a constant flow rate in a closed-loop system with on-line particle counters before and after the test filter. Contaminated fluid is added to the system at a constant rate. Small amounts of fluid are removed before and after the filter for particle counting to calculate the filter efficiency (capture). The capture efficiency is expressed as the Filtration Ratio (Beta) which is the relationship between the number of particles greater than and equal to a specified size (Xμ[c]) counted before and after the filter. In real-world terms, this test is the equivalent of testing a filter in an off-line kidney loop rather than replicating an actual hydraulic or lube system. It’s basically a filter cart test.

DFE: Testing Filters Under Real-Life Conditions (Part 1 of 4)

By Jim Harlan on Tue, Jun. 20, 2017

The Dynamic Filtration Efficiency (DFE) Test is Hy-Pro's standard for testing filter elements. Throughout this four-part series  (find parts two, three and four) we'll discuss what it is, why it matters and why elements engineered with this test in mind outperform others in real-life applications.

First, let's start with the basics.

Why are filters used? How are they rated?

All hydraulic and lube systems have a critical contamination tolerance level that is often defined by -- but not limited to -- the most sensitive system component such as servo valves or high-speed journal bearings. Defining the ISO fluid cleanliness code upper limit is a function of component sensitivity, safety, system criticality and ultimately getting the most out of hydraulic and lube assets.

How a Vacuum Dehydrator Prevented Bearing Failure and Unplanned Outages

By Jim Harlan on Tue, May. 16, 2017

Saves >$15,000,000 by removing water and particulate from common reservoir lube oil.

The Application

In boiler water feed pump applications, water often finds its way into the oil lubricating the pump’s bearings. This was the scenario at a paper manufacturing facility that turned to Hy-Pro for help.

The Problem

In this application, the boiler water feed pump bearing lube system was combined with the facility’s steam turbine lube oil system. The water and the particulate contamination it was bringing with it were decreasing the fluid’s ability to lubricate the bearings and causing premature wear on the bearings.

The facility was attempting to remove free water with water absorbing filters (changed weekly) but the rate of ingression was too high for the filters to be as effective as needed. And since absorbents only remove free water, the filter elements were unable to address the dissolved and emulsified water present in the oil. If the situation were to continue much longer, a premature replacement of the steam turbine and boiler feed pump bearings would be necessary outside of the scheduled maintenance periods. While possible, this solution would cost millions of dollars without addressing the root of the problem.

When a Pump Fails, the Whole System Fails: Hydraulic Pump Reliability

By Jim Harlan on Tue, Feb. 21, 2017

The Problem: Hydraulic Pump Failure 

Pumps are the heart of hydraulic systems. When the pump fails, the entire system is down until the pump is operational again. This poses a serious threat to any operation relying on hydraulic systems for productivity.

Recently, a hydraulic valve manufacturer was losing 25 pumps a year on their centralized hydraulic system at a cost of $2,440 each -- and that’s only the pump cost. When you account for maintenance resources, lost oil and lost production, each failure costs ~$25,320.

By Jim Harlan on Tue, Jan. 03, 2017

The Application

An automotive stamping plant operating large presses to produce body panels was experiencing high surface finish defect scrap. Lubricating oil contamination was causing surface imperfections that would be visible after painting.

The Problem

The uncoiler/washer lube oil system was protected by an off-line filtration system fitted with CJC stacked disc cellulose media filter inserts (elements). Oil analysis revealed an operating ISO code of 23/19/11. Patch analysis showed cellulose fibers were shedding into the oil from the filter inserts downstream of the filtration system.

By Jim Harlan on Tue, Nov. 29, 2016

The Application

A hydraulic valve manufacturer required pristine fluid (< 14/12/9) to test flow across an 80-micron orifice on their test stand. Gross amounts of contamination in the fluid would skew the test results, invalidating any data collected.

[Video] Your Lab Reports Are Probably Wrong -- Here's How To Save Them

By Scott Howard on Tue, Aug. 16, 2016

When looking at a lab report, it is assumed the information on the report is accurate. A certified lab will not usually make an error in the report, but if so, it is obvious and easily fixed. Ever hear the saying "By the time the lab gets the report the error has already been made"? For the most part, this is true. Where people are led off course is believing the particle count on the lab report is the gospel. This is natural, but unfortunately not always the case with a bottle sample unless you already employ the techniques listed in the video below.

Vacuum Dehydrator Called On to Save Fishing Season

By Jim Harlan on Fri, Apr. 15, 2016

One of our V1S vacuum dehydrators was recently put to the test in a marine application with hydraulic oil contaminated by more than 2500 ppm of water. Did it sink or swim? Find out below.

The Problem: Failed Hydraulics Seal and Lost Productivity

When a seal fails on a net hauler hydraulics system out at sea, the costs and lost profits stack up quickly. In this instance, salt water began entering the hydraulic fluid on a 245 ft (75 m) purse seine through a seal leak, rendering the net hauler out of commission.

Faced with frequent fluid exchanges at a cost of $9,300 plus disposal, or worse, substantially larger lost profits from downtime for replacement of the seal, the vessel owner was in desperate need for a solution to allow him to continue operating without fear of malfunctioning equipment.

Conditioning New Oil

By Jim Harlan on Fri, Feb. 19, 2016

Subpar fluid handling practices and inadequate filtration are the leading cause of system reliability issues today. Contaminated hydraulic fluids foul valves and other components causing them to eventually fail and bring your production process to a screeching halt.

This also happens when contamination within lube oils damages the system components the fluid is meant to protect. Your hydraulic fluids and lube oils are the lifeblood of your systems, and on a larger scale your entire operation, so they should be cared for as a precious resource from reception to disposal. One of the best ways to reduce contamination in your system is to prevent it from ever entering it in the first place so let’s discuss the best practices for receiving and storing new fluids.

Filter Sizing: Calculating Clean Element Delta P

By Jim Harlan on Wed, Nov. 19, 2014

Choosing the best filter element size and media for a specific application can be tricky. You want media that is tight enough to help you reach your target ISO code. However, if you choose a media that is too tight for your application, the element differential pressure (Delta P or ΔP) will rise too quickly and you will be replacing elements far too frequently.

To prevent these situations you should always calculate clean element Delta P whenever changing the filter media or manufacturer.

Is Choosing a Sample Port Location Driving You Mad?

By Jim Harlan on Mon, Jul. 07, 2014

The ideal sample port location depends on the purpose for drawing the sample. There are several reasons to draw samples from your hydraulic or lube systems. The main reason is to ensure that the fluid traveling through your system is not loaded with contamination that will damage your pumps, valves and other components.

Secondary reasons include identifying components that are beginning to wear before they fail (this allows you to be proactive about the component replacement or repair) and verifying filter element performance. Continue reading to learn where to take a sample from for each of these reasons. We’ve also included some general fluid sampling tips at the end of this blog.

What is a Vacuum Dehydrator?

By Scott Howard on Mon, Sep. 30, 2013

If the hydraulic, lubricating, compressor or gear oil you use is not made of a water base in formulation , then water is considered a contaminant and must be recognized and managed. 

There are three types of water in a typical system: free water , emulsified water and dissolved water. The water saturation point of most oil, that point above which water is in a free form, is 200-400ppm, depending on age and condition. 

Using 100ppm for an upper water limit for most systems using mineral base oils, this means all free and emulsified water and a significant portion of dissolved water must be removed.

A vacuum dehydrator is one of the very few methods to remove dissolved water from oil. Let's take a look at these three types of water in your system. It will give you a solid foundation for how the vacuum dehydrator works in the end.

How to Keep Your Diesel Clean

By Jim Harlan on Fri, May. 17, 2013

We've all been there -- the power goes out and instant panic sets in. Until you remember that you have a backup generator for just this type of situation. You rely on that generator to run your servers, emergency equipment or entire facility. 

But if you haven't tended to the diesel fuel in your storage tank, it could easily be contaminated with water and particulate, causing failure and requiring expensive repairs. 

One way to keep your diesel clean and dry is to replace the fuel at a set interval. This will ensure that your generator has all it needs to function in case of an emergency; however, it can prove to be costly.

What if we told you that you didn't have to replace the diesel, even if it were contaminated?

How Clean is New Oil? - Part 1

By Jim Harlan on Tue, Apr. 09, 2013

New-OilOP.jpg

Lubricants and hydraulic oil have to go a long way to make it into your system, which means there's a high potential for it to pick up particulate and water at every step along the way.

Around here at Hy-Pro, we cringe when we think about that process and how our customers put that oil into their machines. We want you to be aware of the state of the oil that you're using, so let's take a look at three reasons why new oil does not mean CLEAN oil.

Improving Rolling Mill Lube Oil Performance and Useful Life - Part 3: Solution

By Aaron Hoeg on Mon, Mar. 18, 2013

VUD Vac-U-Dry Vacuum DehydratorAt the end of Part 2, we discussed the winning nature of vacuum dehydration. If you missed Part 1 in the series, you can find it here

Did you know that hydrogen is the friendliest molecule - meaning that it is most likely seeking partners to attach to? Similarly, the suspended particles in oil actively look for particles to join forces, so they pair with the water. 

This particulate contamination is the catalyst guilty of continuing the degradation of the oil and the increase of emulsified water. The more water there is, the more oxidation that occurrs. This also increases various acids that form as the molecules break down. These acids attack seals, hoses, pumps and metal.

Improving Rolling Mill Lube Oil Performance and Useful Life - Part 1: Quality

By Aaron Hoeg on Fri, Feb. 15, 2013

steel mill equipment and lube oil

Premium oils keep steel mills running. It's crucial to protect their quality in order to keep the mills fully functioning. 

In both hot and cold steel mill production, high-demulsibility lubricant is used for backup roller bearing lubrication. Some of these oils are referred to as SD, which stands for super-demulsibility. Not surprisingly, these SD oils are a premium product and come at a premium price. If a manufacturer wants to invest in these big-ticket oils, they obviously want to go to great lengths in order to keep them clean and fully functioning.

Join us for this three-part series as we take an in-depth look at improving rolling mill lube oil performance and useful life.

How to Prevent Gearbox Failure

By Aaron Hoeg on Thu, Jan. 17, 2013

When gearboxes go down, it’s generally because of contamination. This is a costly repair on its own, but once you include the loss of production from downtime, the cost can soar to astronomical figures. Sadly, though, sometimes gearbox failure happens, which wastes your time and money. Let’s take a look at some of the main causes of gearbox contamination and how you can prevent it.

Varnish in Turbine Oil Systems

By Aaron Hoeg on Sun, Nov. 18, 2012

Despite thousands of dollars and hours spent trying to mitigate the effects of varnish in turbine oil, many still suffer from this ongoing yet solvable issue. When combustion and steam turbines fall victim to unit trip or fail-to-start conditions, varnish is the usual suspect.

Hydraulic Oil Water Removal

By Aaron Hoeg on Wed, Nov. 14, 2012

Water, it's a compound that is required for practically everything on the earth. But within a lubrication or hydraulic system, it's one of the most damaging contaminants possible. Unfortunately, it's also one of the most common contaminants you'll find in your system. 

When your lubrication or hydraulic system is continuously or even periodically exposed to high water levels, it can result in a mountain of damage. You can find evidence of water contaminant destruction if you look close enough. This damage appears as :

ISO 4406: What Do Those Numbers Mean in the ISO Cleanliness Codes?

By Aaron Hoeg on Mon, Oct. 08, 2012

Guest post today by Dan Helgerson. He is the Technical Editor of the Fluid Power Journal, where this article was originally published.

We have been talking a lot about filtration here at the steel mill. My predecessor had done a remarkable job in educating by example, demonstrating the need for good control of the fluids in our hydraulic and lubrication systems. He had helped stop the leaks and had added well-thought-out filtration systems that have resulted in substantial savings and increased productivity.

There is still a lot of work to be done and in pursuing that we have invited a number of vendors in, each offering an approach to getting and maintaining an acceptable fluid cleanliness level. The one thing that they all have brought to the table is a discussion of the ISO Cleanliness code. I was in a meeting with a group of managers when one vendor began to talk about the code. Being a Certified Fluid Power Accredited Instructor (AI), I immediately saw this as an obvious teaching moment, so I asked, “Does anyone here want to know what those numbers mean?” The answer was a quick and resounding, “No!”

Glass or Cellulose: Which Hydraulic Filter Media is Best?

By Aaron Hoeg on Mon, Sep. 17, 2012

There are several distinct differences between glass and cellulose media. Media selection should be based on the required cleanliness and other unique needs of the system. Evaluate the Beta ratio (efficiency), dirt holding capacity, flow versus pressure drop characteristics, etc. A hydraulic filter supplier should be able to supply more detailed test information in addition to what is supplied in the literature.

Oil Vacuum Dehydrators: Managing Water in Rolling Mill Lubricating Oil

By Aaron Hoeg on Fri, Aug. 31, 2012

In our last post, Improving Rolling Mill Oil with Vacuum Dehydration, we discussed how the demulsibility (ability of the oil to separate from water) of oil is an important characteristic that greatly influences the effectiveness of the lubricant and how a loss of demulsibility can result in poorly lubricated bearings, unplanned downtime and premature fluid replacement.

Improving Rolling Mill Lubricant Oil with Vacuum Dehydration

By Aaron Hoeg on Tue, Aug. 07, 2012

Steel mills typically use lubricants with high demulsibility for rolling mill back-up roller bearings and chocks since relatively high levels of water contaminate the oil from quenching and descaling processes. These rolling mill lubricant oils may be known as Morgoil as they are commonly used on Morgan rolling mill systems.
