The events were based in the local companies dealing with oil filled equipment, and included two parts, theoretical and practical. The former focused on petrochemical purification and regeneration equipment, such as equipment to remove particulate matter, water and gas and regenerationRead More
Oil degradation is a wide-spread problem in industries using oil-filled transformer equipment. There are many causes of the degrading or aging of industrial oil. Of course, oil “ages in service”, but mostly it ages because it oxidizes, forming oxidation compounds and aging products. The rate of oxidation goes different depending on a number of factors.Read More
March 2-3, 2018 in Houston, GlobeCore held a seminar for representatives of the Texas electric power industry. During the seminar were discussed the issues of aging processes in electrical insulating oils influencing the efficiency of power transformers, including a report on the topic “Purification and regeneration of transformer oils with GlobeCore equipment”. The practical partRead More
March 5, 2018 a regular presentation of oil purification and regeneration equipment was held in the International Training Center of GlobeCore (Oldenburg, Germany). This time the event was attended by representatives from Bosnia and Herzegovina, and their partners from Qatar. First of all, the guests were interested in the possibilities of GlobeCore equipment for processingRead More
February 19-21, 2018, GlobeCore engineering team visited Lucena, Philippines to commission two biodiesel reactors each with capacity 6,25 m3 / h. Currently, the Philippines is experiencing a deficit of oil resources, and is trying to compensate by producing biodiesel from coconut oil. The country also set special programs mandating a minimum of 2 and 5Read More
The second issue from February 2018 of the leading magazine in wind energy “Wind Systems” Magazine, published a Frank May article, entitled “Changing Turbine Gearbox Oil”. The articles discusses the main points to pay attention to when servicing the gearboxes of wind turbines and, in particular, the oil change. It shows the advantages of theRead More
Operation and long storage of lube, turbine and other industrial oil cause contamination of the oil, leading to poor performance. With time, this process causes increased equipment wear, and, in case of electrical insulation oil, failures in electricity transmission grids. It is practically impossible to prevent or stop this process. However, the oxidized oil canRead More
Bitumen emulsion is a binding material, consisting of water and bitumen. Emulsion is a disperse system, with particles of bitumen dispersed in water. The main task is to keep bitumen microparticles from coalescing, which maintains physicochemical properties of the emulsion and its quality. This stability is achieved with special emulsifiers. Bitumen emulsions are transportable, easilyRead More
Although the topic of mixed fuel is relatively new, it is constantly attracting the attention of young and experienced drivers. On hearing about “mixed fuel”, they immediately try to find out what it is and whether it can be used in their cars. Let’s try to understand ourselves. Mixed fuels appeared due to a shortageRead More
Quartz is a natural mineral. It is quite common in the earth’s crust and has a number of important properties: high strength, resistance to fracture, and high sorption properties. Quartz is a component of rocks and minerals, and its mass fraction in the earth’s crust is more than 60%. In industry it is used mainlyRead More
January 20 – 26, GlobeCore employees visited Kuala Lumpur (Malaysia) on a business trip. The purpose of the trip was the CMM-4/7 plant commissioning and the presentation of GlobeCore equipment for the representatives of the electric power industry. The CMM-4/7 performs degassing, drying, cleaning from mechanical impurities and heating transformer oils, before filling them intoRead More
REMOVING IMPURITIES FROM FUEL Fuel Purification is a process mandatory after long term storage or contact with air. There are many methods of removing water and particulate matter from motor fuels. The most common methods are settling, centrifugation and filtration. Of course, all processes have both advantages and limitation, and research into the development ofRead More
Recently, the energy of the wind has become a very popular energy. This method of obtaining energy is environmentally friendly, as it does not produce harmful waste. To better understand wind turbine, let’s consider what kind of equipment it is and how it works. In general, wind turbines are structures carrying a nacelle with bladesRead More
Laying of asphalt surfaces during road repair and construction uses bituminous binders. Bitumen at normal temperatures is a solid or viscous substance. The use of bitumen in this state is impossible, therefore, it is modified in various ways to improve its physicochemical characteristics. Bitumen heated to 100-200°C is used in the preparation of asphalt mixtures.Read More
It would be hard to imagine the modern industries without a variety of machines and mechanisms that improve the production processes in all branches of the national economy. Typically, these machines include knots of friction and adhesion, which wear out in time, due to intensive abrasion of metal parts. The friction is reduced by theRead More
Today, the largest share of consumed lubricants belongs to petroleum based oils. The upward trend of this product requires new and improved existing methods of collection, processing and regeneration. One of the most economical ways of handling oil resources is regeneration of used oil directly on site. As oil aging have a great impact onRead More
It is common knowledge that moisture significantly reduces the insulating properties of transformer oil. The influence of moisture in oil is different depending on the temperature and the amount of moisture and the state it is present in a dielectric fluid. The moisture in oil can be present in three states: emulsion, solution and sedimentedRead More
When the transformer is under load, the energy loss in the magnetic core and the windings turns into heat which can damage insulation. It is important to keep a close watch on the temperature inside the equipment to prevent overheating and possible fires at substations. The main part of transformer cooling in this case isRead More
Grinding precision is one of the main parameters of cement quality. This construction material is one of the few, whose strength is improved by interaction with molecules of water. It is important to ensure thorough hydration of the substance. Apparently, water binds smaller particles better. Specific surface is the parameter used in laboratory conditions toRead More
