  Contamination is the major cause of failure for any lubricated mechanical element. Wear can easily be identified by monitoring the shape and composition of contaminants. To identify and monitor the source of contaminants, Particle Analyzer plays a very crucial role. It analyzes the solid contamination in a lubricant by counting the number of particles and categorising the degree of contamination according to the particle size. The particle analyzer is considered to be one of the most important tests in oil analysis, as it determines a wide variety of problems easily. It monitors the amount and size of the particles in an oil sample. There are many uses of particle analyzer including testing filter leaks, checking real-time cleanliness and filter efficiency, creating testing routines, etc. Benefits of Particle Analysis There are enormous benefits; some of them are as follows: It allows “real-time” analysis of oil It confirms the corrective maintenance, needs for ferrography, and syste

  Greasing is an important process that ensures the smooth functioning of machines. Let’s understand these two aspects first - Over greasing and Under greasing. To determine which of these is more problematic could be difficult but we can definitely decide which one is more damaging. Too much grease can generate excessive heat in the bearing and may result in seal failure. When the lip seals rupture because of over greasing, it allows the harmful contaminants to enter the bearing housing. This would create excessive pressure and may collapse the bearing race. On the other hand, not putting enough grease may cause damage to the rotating parts. Under greasing allows contaminants to enter the load zones. We can say that it's better to avoid both aspects of over and under greasing. How to determine the amount of grease a bearing needs? The factor responsible for determining the right amount of grease depends on the dimensions of the bearing or its housing. Greasing must be done based o

  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 that can operate under extre

  Routine Oil sampling and analysis are crucial for a successful maintenance program. It provides important information to determine the condition of the equipment. Sampling is a vital procedure for collecting fluid from machinery for the purpose of oil analysis. The results and reports of oil analysis depend on the quality of the oil sample. Thus, oil sampling must be performed keeping some important goals in mind - To MAXIMIZE the Data Density. To MAXIMIZE Consistency. To MAXIMIZE Relevance. To MINIMIZE Data Disturbance. There can be three ways of extracting samples from a component - drain port, drop-tube (in a vacuum pump), and a dedicated sampling point. A common mistake is taking an oil sample from the reservoir in circulating and hydraulic systems. Taking samples from the tank is not a best practice. If the sample is taken from the drain lines before emptying the tank, the concentration of wear metal would be much higher. Let’s discuss the common mistakes of oil sampling which c

  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. For accurate oil analysis, c

  As Wendell Berry once said, "The Earth is what we all have in common." Earth Day is the only secular festival on the globe. This celebration aims to thank mother earth for nurturing us and giving us all it has. People swear to plant trees, restore the earth, and not exploit the environment. Every year we see many initiatives taken to save the earth on this day but do we really achieve it? Now we need to measure the changes after taking specific steps. From a recent survey, we can see that ten out of the 15 most polluted cities in the world are from India. It has not been six months since all the heads of 197 countries attended the COP26 in Glasgow, Scotland. The primary concern of the billion-dollar event was to maintain the earth's temperature. As the theme of Earth day for this year suggests, ‘Invest in our Planet’, we need to invest instead of paying later for getting fresh air, pure water, organic food, etc. Do you know Contaminated oils are very harmful to the envi
