吉田 陽一MemberNatural ester oil is used as an insulating and cooling fluid in transformers, enhancing performance while being environmentally sustainable.
November 20, 2024 at 10:23 pm in reply to: How is the penetration index calculated, and what does it signify? #131311吉田 陽一MemberThe Penetration Index (PI) is calculated using penetration and softening point test results. It signifies the temperature susceptibility of bitumen—the degree to which its hardness changes with temperature. A higher PI indicates lower temperature susceptibility, meaning the bitumen maintains consistent performance across temperature variations.
November 20, 2024 at 8:24 pm in reply to: What role does asphalt emulsion binder play in road construction? #131291吉田 陽一MemberThe binder provides adhesion between aggregates, creating a cohesive and durable pavement layer. It also imparts flexibility and resistance to cracking and deformation under traffic loads.
November 19, 2024 at 10:56 am in reply to: What are bituminous emulsions and their applications? #130954吉田 陽一MemberBituminous emulsions are stable mixtures of bitumen and water, used extensively in road construction and maintenance. Applications include surface dressing, where they provide a protective layer over existing pavements; tack coats, which enhance adhesion between pavement layers; and cold mix asphalt for road repairs. They are also used in microsurfacing and slurry seals to fill minor cracks and improve surface texture. Bituminous emulsions are favored for their ease of application, energy efficiency, and environmental benefits, such as reduced emissions and lower energy consumption during application.
October 9, 2024 at 9:32 am in reply to: What are the top techniques for silica gel reactivation? #123663吉田 陽一MemberSilica gel reactivation can be achieved through several techniques, including oven drying, microwave heating, and using dedicated regeneration equipment. Oven drying involves heating at 120-150°C for 2-3 hours, while microwave heating requires lower times but careful monitoring to avoid burning. For industrial applications, GlobeCore provides automated regeneration systems that ensure consistent and efficient reactivation. These systems maintain optimal temperatures and airflow, ensuring the silica gel is thoroughly dried, making them ideal for large-scale reactivation needs.
October 7, 2024 at 3:41 pm in reply to: What materials are commonly used in high voltage transformer bushings? #123182吉田 陽一MemberCommon materials used in high voltage transformer bushings include porcelain, resin-impregnated paper (RIP), and resin-bonded paper (RBP) for insulation. Porcelain is typically used for outdoor bushings due to its durability and resistance to environmental factors. RIP bushings use paper impregnated with resin, providing high dielectric strength and moisture resistance. Some modern bushings use epoxy resin as insulation, which offers good mechanical strength and resistance to environmental stress. The oil or gas within the bushing also serves as an insulating and cooling medium.
October 7, 2024 at 11:26 am in reply to: What are the main components of a condensate polishing system? #122924吉田 陽一MemberThe main components of a condensate polishing system include mechanical filters, ion exchange resin columns, and mixed-bed resin units. Mechanical filters remove suspended solids, while ion exchange resins remove dissolved salts and other ionic impurities. Mixed-bed resin systems, which combine cation and anion exchange, are often used for final polishing to achieve high-purity condensate. Other components may include activated carbon filters to remove organic contaminants, pumps to circulate the condensate, and monitoring instruments to track parameters such as conductivity and pH. Regular maintenance of these components is essential to ensure effective operation.
October 7, 2024 at 10:50 am in reply to: What are the environmental benefits of Midel-filled transformers? #122843吉田 陽一MemberMidel-filled transformers are environmentally friendly due to the biodegradable nature of the oil. In case of spills, Midel oil has minimal environmental impact compared to traditional mineral oils. Additionally, its non-toxic properties make it safer for ecosystems. The use of Midel oil reduces the risk of transformer fires, further limiting potential environmental damage.
October 7, 2024 at 10:13 am in reply to: How is sludge removed from wind turbine transformer oil? #122805吉田 陽一MemberSludge is removed from wind turbine transformer oil through a combination of filtration and oil regeneration processes. Filters capture sludge particles, while chemical treatments during regeneration break down and neutralize sludge-forming compounds. Vacuum degassing may also aid in the removal of moisture and gases that contribute to sludge formation, ensuring the oil remains clean and effective for long-term use.
October 7, 2024 at 6:47 am in reply to: What steps are involved in the fuel oil polishing process? #122592吉田 陽一MemberThe fuel oil polishing process involves several steps: first, fuel is pumped from the storage tank into the polishing system. Water and large contaminants are separated and removed using filtration and centrifugation. Fine filters then capture smaller particulates. Finally, the cleaned fuel is returned to the storage tank, ensuring it meets the required quality standards for use in engines or generators.
October 5, 2024 at 8:36 am in reply to: How do Automated Diesel Fuel Purification Systems improve operational efficiency? #122425吉田 陽一MemberAutomated Diesel Fuel Purification Systems significantly enhance operational efficiency by streamlining fuel management processes. Real-Time Monitoring allows continuous assessment of fuel quality, enabling immediate adjustments to purification parameters without manual intervention. Consistent Fuel Quality ensures that diesel remains free from contaminants, optimizing engine performance and reducing the likelihood of breakdowns.
