Contaminant Composition Aging of mineral oil occurs due to accumulation of contaminants with adverse effects on the operation of engines and machines. When motor oils become contaminated, the wear of the piston engine parts and carbon deposition increases, oil conduits and filters become clogged, normal operation and temperature of friction parts and the engine areRead More
Rapid degradation of transformer oil quality may occur not only due to insufficient chemical stability, but also due to the influence of construction and insulation materials used in a transformer. The most active catalyst of transformer oil oxidation is copper. The opinions of researchers regarding the influence of iron, aluminum, nickel and zinc are divided.Read More
The reliability of high voltage transformers in severe operation conditions is mainly defined by the quality of insulation oil. Mineral transformer oil is widely used for cooling and electrical insulation in oil-filled electrical systems. Transformer oil is a product of crude oil refining, and its chemical composition is largely determined by the hydrocarbon composition ofRead More
Power distribution and supply systems rely on transformers, which convert voltage and amperage at the same frequency and at the same power. Reliable transformer operation depends on the condition of its insulation system, which consists of cellulose insulation and dielectric oil. Such oil is also used in other electrical equipment, such as switches, cables etc.Read More
In many countries around the world today most of the transformers in operation were commissioned in the end of the previous century. That is why the issue of equipment replacement or lifetime extension is becoming important now. Power generation and distribution facilities must make decisions on the future strategy of improving the reliability of operatingRead More
This article is about oil reconditioning and the equipment required for this process. Let us first consider the basic types of modern industrial oil, their purposes and application. Classification of oils in the industry The main application of oils is lubrication of internal combustion engines. Depending on the purpose, the oils are classified as follows: dieselRead More
Natural energy reserves are unevenly distributed, making shortages of energy resources common in many countries. This is an incentive for three things: looking for less expensive imports, saving energy and developing alternative heat and energy sources. According to industry professionals, coal-water fuel (also known as CWF or coal slurry) is a promising product. CWF isRead More
Reliability and efficiency of modern electrical grids depends on power transformers. Transformer failures are down time can be very costly. All things considered (the cost of a new transformer, disposal of the failed transformer, transportation, installation etc), the expenses may run into millions of dollars. The primary cause of transformer failure is damaged insulation, whichRead More
The contamination of transformer oil during transportation and storage is not only particulate matter, but also water and gases from the air. The oil begins to age, and its parameters degrade: acid number and dissipation factor grow, while its dielectric strength decreases. This makes drying and degassing of oil imperative to keep the oil inRead More
Wind Turbine Flushing is a process used in many types of industrial equipment to prevent faults related to the oil system. This article deals with oil flushing of hydraulic systems and wind turbine gearboxes. The purpose of Wind Turbine flushing When oil filled equipment is operated, several processes influence the quality of oil. These areRead More
Both natural materials (bleaching clays, natural bauxites and zeolites) and synthetic substances (silica gel, aluminum oxide, alumina silicate catalyst and synthetic zeolite) are used for adsorption purification of mineral oil. Bleaching clay, silica gel, aluminum oxide and alumina silicate are used mostly for waste oil regeneration. Aluminum silicate used as adsorbents vary widely in chemicalRead More
Literature contains much information on using bitumen emulsions in road construction. Damaged bitumen surfaces Surface damage. The beginning of surface damage is easily visible after rain. The first indications of surface destruction can be identified by finding wet spots on an otherwise dry surface. These may be caused by insufficient binder content in the surface,Read More
Practical experience of marine power plant operation shows that their reliability, mean time between failures and time before overhaul depends on operation parameters related to fuel quality. Many river vessels use diesel fuel and fuel oil for propulsion. Fuel always contains sulfur and its sulfuric compounds (mercaptans, sulfides, disulfides etc). These substances reduce quality andRead More
Any oil used in electrical equipment must comply with certain requirements. I.e. its quality and parameters must not be below the values stated in regulatory documents and equipment manuals. Any deviation may lead to transformer malfunction and outrage. Some of the most important indications of oil quality are its dielectric strength, moisture and gas content.Read More
Both production volume and consumption of biodiesel have been growing due to two main factors. First, the global environmental deterioration, caused mainly by the emissions from burning fossil fuel. Second, this deterioration caused tightening of exhaust emission regulations. Many countries have adopted laws to gradually increase the share of biodiesel used as fuel. The selectionRead More
Vacuum is understood as a certain area of space with pressure less than that of the ambient atmosphere. There is also the concept of the ideal or absolute vacuum: a space totally devoid of matter. However, achieving this condition is impossible. The former definition is usually used. The degrees of vacuum The range of pressuresRead More
Petroleum based oils have a wide range of industrial uses. They lubricate, dissipate heat and provide electrical insulation in high voltage systems. The oils age in use, their performance degrades and ultimately, a large amount of potentially hazardous waste is generated. This article deals with: disposal of oil; oil regeneration; oil re-refining. Used oil disposalRead More
A seminar on purification and regeneration of industrial oils, as well as power transformer servicing, was held in Mexico City on 29 November 2018. This seminar became one of the most attended events recently held by GlobeCore. The number of participants reached approximately 100, representing 40 companies from Mexico, Salvador and Guatemala, which are relatedRead More
GlobeCore began in 1969. It was then when a new company, originally serving the agricultural industry, was formed. Today GlobeCore is a world leader in the production of oil purification and filtration machines. In this article we show the progress of our company in the last 50 years. The focus of purification and regeneration ofRead More
