  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

  In our last #knowyouroil segment, we had discussed about   Particle Contamination   and its effect on the life of rotating parts. Companies spend a lot of money on installing filtration units to counter particle contamination but never take preventive measures towards water contamination. Water is a worse and silent killer for the life of machinery as it slowly degrades the oil properties and one only gets to know about it when the machine fails pre-maturely. In this article, we will try to understand the basics of Water Contamination. We will also try to answer the following questions. What water does to oil properties? Can we see water contamination as soon as it starts? What to do if our oil is contaminated? To check your machine's, follow:  https://www.linkedin.com/company/minimacsystemsprivatetlimited  There are three phases in which water can exist in oil i.e. dissolved water, emulsified water, and free water. Dissolved Water:  It is characterized by individual water molecu

  A bypass filter, also known as a pressure relief valve, is a very important part of an oil filter. When oil is too thick or the filter is clogged, the valve opens. If the valve doesn’t open then the filter may eventually burst. Bypass filters are designed to remove fine organic and inorganic particles. It also increases the total volume of oil used. Thus, if you have contamination issues and want to extend operating equipment life, extend lube oil & service intervals, and consider adding bypass filters. We can say that Bypass filtration can be considered another aspect to save money and downtime. Most of the existing manufacturers use ‘full-flow’ oil filters which are designed to protect the component from large particles but they cannot remove soot, water, or silt. Full-flow filters alone cannot keep oil clean for a long-term period. The fine particles which account for most of the contamination can be removed by the bypass filters. It is advised to do the homework before buying
