As a part 2 of #knowyouroil series, we will discuss about  Particle Contamination . Whenever we talk about contamination the first thing that comes to our mind is solid particles that we can see or feel. But what we do not understand is how big a particle can really cause wear and tear to your machines, can all contaminants be seen with naked eyes? Is it too late to wait until then?                                                                                      To answer the above questions we must first understand the actual clearance size of the different types of lubrication film formed between   rolling   and   rotating  components which is essential for providing proper lubrication. Oil film thickness in machinery is measured in microns (µm), or one-millionth of a meter. For queries related to Oil Testing, follow:  https://www.linkedin.com/company/minimacsystemsprivatetlimited Below are the finest tolerance found in different types of components. When small pa

Oils are used to reduce friction, heat and wear between mechanical components that are in contact with each other. Lubricants are like the blood of your machines. As blood sampling represents the well being of a human body so does the lubricants in case of machines. However, a wrong sampling technique might not reveal the true condition of the machine and thus, leads to the wrong representation and pre-mature breakdown. Thus, MINIMAC SYSTEMS is starting this #knowyouroil series under which we will make you aware of: How to collect a sample  Type of contaminants and how they are harmful for your machines Oil analysis and how to decode it.  Oil changes are mostly done under two conditions: On the basis of time or operating hours. On the basis of oil condition. Most of the time, changing oil based on time or operating hours is expensive and hence, changing based on oil condition is more viable. At this juncture, an Oil Analysis Report is key to decision making

There are four basic functions of hydraulic oil : To act as an energy transmission medium. To Lubricate internal moving parts of components. To act as a heat transfer medium. To seal clearances between moving parts. If any of these functions is impaired, the hydraulic system in the equipment/rigs will not perform as designed. The resulting downtime can cost a lot in Dollar and increase the operating cost for any rig/operations on field. Proper hydraulic fluid maintenance helps to prevent or reduce breakdown maintenance. This is accomplished through continuous improvement program that minimizes and removes contaminants. Hydraulic fluid is expected to create a lubricating film to keep precision parts separated. Ideally, the film is thick enough to completely fill the clearance between moving parts. This condition results in low wear rates. When the wear rate is kept low enough, a component is likely to reach its intended life expectancy. The actual thickness of a

What is a Turbine EH System ?  Electro-Hydraulic Control System  (EHC System) of a Turbine is the most critical equipment of a Power Plant. It’s the heart of a turbine which controls Steam flow into the turbine. A malfunctioning   EHC System   can lead to Turbine stoppage and thereafter create a dominoes effect on the synchronized processes of the power plant. Breakdown-free and reliable operation of the EHC System is the biggest challenge of an Operation & Maintenance Manager. To learn more follow   https://www.linkedin.com/company/minimacsystemsprivatetlimited Due to High Steam Pressure & Temperature in the vicinity of a Steam Turbine, as safety compliance, it is a mandate to use   Fire Resistant Fluids   (FRF) for Hydraulic control of the EHC System. A specially designed synthetic fluid called   Tri-Xylenyl Phosphate Ester  demonstrates best Fire Resistant properties for the application. Phosphate esters are polar fluids with excellent lubricating properties

T he condition of the oil in lubrication and hydraulic systems is indicative of the health of the entire system. There are two essentials for ensuring productivity, for avoiding malfunctions and for  reducing operating costs:         1.  Monitoring the fluid condition        2.  Continuous maintenance of operating equipment Varnish is a soluble and insoluble contaminant made up of by-products of oil degradation and oxidation. It can appear as a gel-resin like consistency or resemble solid deposits in the oil, or which plates out on the metal surfaces of lube systems. It can be the result of several possible root causes, including high temperatures, electrostatic discharges, lubricant degradation and micro dieseling. Varnish can produce a number of problems related to machine operation, such as valve stiction, lubricant flow restriction, clogged filters, etc. How is Varnish different from Sludge?   Varnish is a tough, adherent oxide or carbonaceous material that coats
