  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 e...

  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 whi...

  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 o...
