T11 Optimol SRV 4 Machine (New Machine)

The Optimol SRV 4 apparatus (SRV is a german acronym for oscillation, friction and wear) is a multiple lubrication test machine. It is
versatile in the sense that most of the tests parameters are editable by means of the installed software. These parameters mainly include: load,
stroke, temperature, load stepsize, machine cut-off values etc.

Basic tests include:

A constant load test (like the HFRR)
An increasing load test where the load increases @ 50N/min to evaluate the Load Carrying Capacity (LCC). This test is also known as a film life test.

The machine traditionally tests the lubricating properties of oils and greases, but at the University of Pretoria it is used to test diesel lubricity together with the HFRR

There is no ASTM or ISO standard for testing diesel fuel with the SRV but the "in-house" test developed for testing diesel utilizes conditions that are closer to that of modern engines, when compared to the HFRR.

=== The SRV Open Gear Lubricants Procedure ===
Download the [ftp://anonymous@ragnarok.up.ac.za/publicftp/lab/Tribology/SRV/34_Testing_wear_on_the_Optimol_SRV_Test_System_pdf_%20SRV%20DIESEL%20LUBRICITY%20TEST%20DESCRIPTION_pdf_%20SRVbalgprent_doc_%20D5706_SRV%20EP__PDF_%20D5707_SRV%20Friction%20Folder/BE%40UP%20Tribology%20lab%20Test%20Descriptions%28SRV%20OGP%29.pdf SRV OGP Test Description]

The SRV test procedure for open gear lubricants (SRV OGP Procedure) is intended as a screening test for the performance of open gear lubricants. A load test as well as a friction and wear test is performed at three temperatures, namely 25, 55 and 80°C. A ring is fitted around the top specimen and filled with grease, prior to the onset of the test, so as to ensure that the surfaces in contact are always replenished with lubricant and no starvation occurs, as might be the case when higher- consistency greases are tested without a ring.

=== SRV Diesel Test Procedure ===

The ball, disc, tweezers and other hardware and utensils are cleaned in the same manner as used for the HFRR. After the acetone wash, the specimens and hardware are left to air dry on a clean paper towel.

Once the disk is dry, it is wrapped in Teflon tape and the sample retaining ring is placed over the disc and secured into place. The ball is placed into the triangular chuck and the microscope used to ensure an undamaged surface is used for the test. The chuck is then secured onto the test rig and the disc and sample retaining ring also clamped into place.
The discharge end of the fuel feed system is connected to the inlet of the sample retaining ring and a plastic tube is placed over the discharge end of the sample retaining ring to allow for overflow of fuel to go into a beaker set in place for this purpose.

The chamber was then closed. The sample is then allowed to cover the disc and then the feed rate is controlled at 1 drop every 3 seconds. The initial 50N load is applied and the test started. The test is automatically stopped when breakthrough occurrs, once a friction coefficient of 0.3 is exceeded.

The Optimol SRV 4 apparatus (SRV is a german acronym for oscillation, friction and wear) is a multiple lubrication test machine. It is
versatile in the sense that most of the tests parameters are editable by means of the installed software. These parameters mainly include: load,
stroke, temperature, load stepsize, machine cut-off values etc.

Basic tests include:

A constant load test (like the HFRR)
An increasing load test where the load increases @ 50N/min to evaluate the Load Carrying Capacity (LCC). This test is also known as a film life test.

The machine traditionally tests the lubricating properties of oils and greases, but at the University of Pretoria it is used to test diesel lubricity together with the HFRR

There is no ASTM or ISO standard for testing diesel fuel with the SRV but the "in-house" test developed for testing diesel utilizes conditions that are closer to that of modern engines, when compared to the HFRR.

The SRV test procedure for open gear lubricants (SRV OGP Procedure) is intended as a screening test for the performance of open gear lubricants. A load test as well as a friction and wear test is performed at three temperatures, namely 25, 55 and 80°C. A ring is fitted around the top specimen and filled with grease, prior to the onset of the test, so as to ensure that the surfaces in contact are always replenished with lubricant and no starvation occurs, as might be the case when higher- consistency greases are tested without a ring.

=== SRV Diesel Test Procedure ===

The ball, disc, tweezers and other hardware and utensils are cleaned in the same manner as used for the HFRR. After the acetone wash, the specimens and hardware are left to air dry on a clean paper towel.

Once the disk is dry, it is wrapped in Teflon tape and the sample retaining ring is placed over the disc and secured into place. The ball is placed into the triangular chuck and the microscope used to ensure an undamaged surface is used for the test. The chuck is then secured onto the test rig and the disc and sample retaining ring also clamped into place.
The discharge end of the fuel feed system is connected to the inlet of the sample retaining ring and a plastic tube is placed over the discharge end of the sample retaining ring to allow for overflow of fuel to go into a beaker set in place for this purpose.

The chamber was then closed. The sample is then allowed to cover the disc and then the feed rate is controlled at 1 drop every 3 seconds. The initial 50N load is applied and the test started. The test is automatically stopped when breakthrough occurrs, once a friction coefficient of 0.3 is exceeded.

A ring is fitted around the top specimen and filled with grease, prior to the onset of the test, so as to ensure that the surfaces in contact are always replenished with lubricant and no starvation occurs, as might be the case when higher- consistency greases are tested without a ring.

=== SRV Diesel Test Procedure ===

The ball, disc, tweezers and other hardware and utensils are cleaned in the same manner as used for the HFRR. After the acetone wash, the specimens and hardware are left to air dry on a clean paper towel.

Once the disk is dry, it is wrapped in Teflon tape and the sample retaining ring is placed over the disc and secured into place. The ball is placed into the triangular chuck and the microscope used to ensure an undamaged surface is used for the test. The chuck is then secured onto the test rig and the disc and sample retaining ring also clamped into place.
The discharge end of the fuel feed system is connected to the inlet of the sample retaining ring and a plastic tube is placed over the discharge end of the sample retaining ring to allow for overflow of fuel to go into a beaker set in place for this purpose.

The chamber was then closed. The sample is then allowed to cover the disc and then the feed rate is controlled at 1 drop every 3 seconds. The initial 50N load is applied and the test started. The test is automatically stopped when breakthrough occurrs, once a friction coefficient of 0.3 is exceeded.

Used to:
#Measure wear scar and/or wear track size
#Capture wear scar and/or wear track appearance.

Typically used with:
#BOCLE
#SL-BOCLE
#HFRR
#SRV

The microscope is used to capture an image of a contact surface after a lubricity test was performed. The surface appearance of the wear scar can then be rated and the wear scar measured. The microscope is equipped with three lenses that are used to obtain different enlargements of the image. These include a 5x-, 10x- and 20x zoom.

Below is an image of the microscope without the camera.

==What Exactly Is Tribology?==

[[File:Lubricating-Oils.jpg|right]]

In essence, tribology is the science and engineering of interacting surfaces in relative motion. This includes research and application of friction, wear and lubrication.
(Mang, Bobzin & Bartels, 2011: 1)

==Theoretical Background==

Research in the Tribology laboratory at the University of Pretoria centres mainly around the study of lubricants and their lubricity, particularly that of diesel. Lubricants applied to mechanical systems generally form a film or separating layer between two interacting surfaces which reduces wear rates and the coefficient of friction. The coefficient of friction is defined as the ratio of the frictional force to the normal force of the load applied to the surface concerned (Mang et al, 2011: 26). Lubricity can be seen as a measure of how effective a lubricant a particular fluid is. Lubricity cannot be measured directly and is therefore determined by the amount of wear on an interacting surface. Wear is defined as the progressive loss of material from the surface of a solid object due to mechanical causes-that is, the contact with and frictional motion against a solid, liquid or gaseous counter body (Mang et al, 2011: 37).
Various types of wear include adhesion, abrasion, corrosion, tribochemical reactions (usually oxidation) and surface fatigue (Mang et al, 2011: 38). Ultimately the more wear experienced by two interacting surfaces the worse the lubricity of the lubricant applied to the surfaces.

The Lubricity of a fuel depends on factors such as (www.biodiesel.org, 26 November 2011)
the composition of the crude oil source from which the fuel was produced (sulphur found in the original source has good lubricity properties but much of it is removed due to environmental concerns),
the refining processes used to produce the fuel and the handling of the fuel during distribution.
The addition of lubricity enhancing additives (such as antioxidants, viscosity modifiers and many others)also has an affect on the lubricity.

==Tribology Laboratory - University of Pretoria==

[[File:Tribpic.jpg|300px|right]]

The tribology group is headed by Professor Philip de Vaal and was started in 1987 with support from ESKOM, Anglo-American and ISCOR. The activities in the lab focus on lubricant performance evaluation, which includes analysis of greases, oils and diesels. More recent industrial problems with diesel quality in South Africa motivated research in the field of diesel lubricity and biodiesel, sponsored by Sasol.

The Tribology Lab not only functions as a academic research lab, but also as an evaluation lab for industry. Several companies use the Tribology Lab for failure analysis and quality control.

The first section gives information regarding the '''[[Tribology#Equipment|equipment]]''' used in the Tribology Lab. The user manuals, test procedures and ASTM/ISO/DIN/SABS standards for each piece of equipment is included in the respective pages. Documentation of past and present projects can also be found there.
