Oil Vacuum Dehydrators: Managing Water in Rolling Mill Lubricating Oil

By Aaron Hoeg on Thu, Apr. 29, 2021

Managing Water in Rolling Mill Lubricating Oil

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 Thu, Apr. 22, 2021

Benefits of Vacuum Dehydration for Rolling Mill Lubricant Oil

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.

Demulsibility

What is Demulsibility?

Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.

Understanding ISO Codes

By Brad Bainbridge on Thu, Feb. 25, 2021

ISO Cleanliness Codes Explained

The ISO Cleanliness Code (per ISO4406-1999) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes - 4µ, 6µ, and 14µ. It is expressed in 3 numbers (example 19/17/14) where each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger.Screen Shot 2021-02-23 at 2.50.37 PMIt is important to note that each time a code increases, the quantity range of particles is doubling. Inversely, as a code decreases by one the contaminant level is cut in half.

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

By Brad Bainbridge 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 Brad Bainbridge 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.

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

By Brad Bainbridge 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.

Hydraulic Valve Performance Test Stands and Clean Oil

By Brad Bainbridge 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.

The system held 100 l (26.4 gal ) of ISO VG 32 fluid with a flow rate of 25 lpm (6.6 gpm ).Through observing the manufacturer’s sampling practices, discussing fluid handling best practices and interpreting their lab reports, three independent problems were identified:

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

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.

Filter Sizing: Calculating Clean Element Delta P

By Brad Bainbridge 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.

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.

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.

What Are the Causes of Varnish in Hydraulic Oil?

By Aaron Hoeg on Wed, Nov. 07, 2012

The Problem of Varnish Contamination 

Varnish contamination is the inevitable byproduct of many degradation processes in hydraulic and lubrication systems. The effects of varnish on industrial and manufacturing systems range from the nuisance of minor downtime and routine maintenance to, worst case scenarios, multi-million dollar catastrophic failures of major capital equipment.

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 Filter Media?

By Aaron Hoeg on Mon, Sep. 17, 2012

Glass or Cellulose: Which Hydraulic Filter Media is Best?

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

Benefits of Vacuum Dehydration for Rolling Mill Lubricant Oil

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.
