  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.

When small particles, which cannot be seen through human eyes, pass through the critical machine parts under l

  Oxidation Stability:  Oxidation stability is a chemical reaction that occurs with a combination of the lubricant and oxygen. The rate of oxidation is accelerated by high temperatures, water, acids, and catalysts such as copper. The service life of a lubricant reduces with an increase in temperature. Viscosity Index:  The viscosity index (VI) is an arbitrary, unit-less measure of a fluids change in viscosity relative to temperature change. It is mostly used to characterise the viscosity-temperature behaviour of lubricating oils. The higher the VI, the more stable the viscosity remains over temperature fluctuations. Filterability:  Capable of being filtered or separated by filtering. Low Sludging Formation Tendency:  Having low sludge formation tendency.

  It is a well-known fact that lubricant’s key responsibility is surface separation and protection. It reduces friction and saves a lot of costs that a company incurs in events of premature failure. One of the things that people talk about very seldom is when to lubricate and how much to lubricate. Does over lubrication saves or increases the maintenance expense? Is there a sweet spot or optimum point for lubrication? In this article, we will discuss how to work around your lubrication schedule to save on operational costs and simultaneously reduce energy consumption? To get answers ping us: +91 7030901266 As presented in a report by Dr. H. Peter Jost’s Projected Economic Benefits Associated With Improved Lubrication Design and Practice,  “A large percentage of lubrication programs operate inefficiently and on auto-pilot”. Some of the properties where too little or excess consumes too much energy: Viscosity Grease Consistency Grease Load Oil Volume Filtration Grease Bleed Summability:

  The cost of removing dirt from oil is substantial, mainly when plants and fleets operate in dusty environments. We are aware of the fact that contamination control is optional but an important maintenance strategy. You may find it surprising, but most oils purchased these days are not filtered before being sold. It may look transparent, but it has particles that are not expected to be in new oil. The existing contaminants of lubricants must be addressed first before putting into service. Achieving cleanliness of oil at economical rates should be taken care of by smart maintenance professionals. As already mentioned, many new lubricants may have impurities that contribute to premature filter plugging. An oil change can be more economical than filtration (in some cases). In simple words, filters last if they don’t plug in particles/impurities. A careful inspection must be done in this case. If you change filters very often, it will be a waste of resources. The additional cost includes

  Have you ever thought when you raise a requirement for a particular filter let’s say a 10-micron filter you get a range of prices some being ridiculously low and some being higher than most, and all claim to give the best 10-micron filter? We get tricked at this point and without looking at differences we think that the only differentiator is the profit margin and procure the filter with the least price. For filter check contact - +91 7030901266. Let’s try to understand the real reason for the price difference. There are two types of filter ratings: Absolute:  Filter Rating meaning 99.9% of the particles larger than a specified micron rating will be trapped on or within the filter. Nominal:  Filter Rating indicating the approximate size particle, the majority of which will not pass through the filter. It is generally interpreted as meaning that 85% of the particles of the size equal to the nominal filter rating will be retained by the filter. So, a vendor quoting for an Absolute 10-m

Control System The turbine control system describes the control over the opening of control valves corresponding to demand signals, and steam flows into the turbine with the help of a governing system that facilitates the operation of the turbo set in an interconnected grid system. Governing system is responsible for various function such as speed & load control functions, the start-up/shut-down controls, the over-speed control, turbine stress calculation, to control the initial run-up and synchronization of the Unit, to assists in matching the power generated to that demanded by responding to system frequency changes, to regulate the steam control valves position (and hence the load generated)in response to signal from the operator or from the load dispatch Centre, to restrict the speed rise within acceptable limits should the unit get disconnected (islanding) from the lgridoad and some protective trip functions.
