julio 30, 2025 a las 5:08 am en respuesta a: What is a BDV transformer test and why is it performed? #322986伊藤 聡太郎Miembro
A BDV transformer test checks the dielectric strength of insulating oil, detecting contamination or degradation. GlobeCore systems ensure oils meet BDV thresholds by providing high-vacuum purification and regeneration.
julio 29, 2025 a las 5:00 am en respuesta a: How much is used transformer oil worth and how can it be reused? #322841伊藤 聡太郎MiembroUsed transformer oil prices vary by condition and region, but most aged oils can be regenerated to like-new quality. GlobeCore regeneration plants remove acids, sludge, and gases, allowing utilities to reuse oil instead of replacing it.
julio 29, 2025 a las 12:55 am en respuesta a: What can be done with used oil-filled transformers to keep them operational? #322819伊藤 聡太郎MiembroUsed oil-filled transformers can be serviced by purifying and regenerating their insulating oil to restore dielectric strength. GlobeCore offers mobile and stationary plants that clean and recycle oil, extending transformer reliability.
伊藤 聡太郎MiembroThe price of bitumen emulsion depends on grade, emulsifier type, and production capacity. GlobeCore equipment enables producers to maintain competitive pricing while ensuring product consistency.
伊藤 聡太郎MiembroThe easiest method to test hydraulic oil for moisture is to use a portable tester like GlobeCore TOR-1, which delivers fast, on-site results without the need for laboratory analysis.
julio 23, 2025 a las 12:57 pm en respuesta a: How to comply with IEC standards for residual gas testing in transformer oil? #322082伊藤 聡太郎MiembroThe GlobeCore TOR-8 meets IEC 60567 and ASTM D3612 standards for dissolved gas extraction and analysis, ensuring compliance with international transformer diagnostic practices.
julio 23, 2025 a las 9:25 am en respuesta a: How to avoid transformer issues with FR3 dielectric fluid testing? #322023伊藤 聡太郎MiembroRegular testing with GlobeCore TOR-7 identifies water, particles, and insulation degradation early, helping prevent transformer failures and outages.
abril 6, 2025 a las 2:11 am en respuesta a: Which transesterification processes or catalysts are most reliable for dealing with the unique characteristics of cod liver oil? #317859伊藤 聡太郎MiembroDue to its high FFA content, cod liver oil may require acid esterification (using H₂SO₄) before base-catalyzed transesterification with NaOH or KOH. A two-step method is most effective. For cleaner oil, base catalysis alone suffices. The GlobeCore USB plant supports both acid and base catalysis, with automated control of reaction stages, methanol ratios, and catalyst dosing, making it ideal for processing marine oils like cod liver. Enzymatic transesterification is also an option for small-scale, high-purity applications but is costlier.
abril 4, 2025 a las 10:17 pm en respuesta a: Which catalysts or additives are most effective for converting mustard seed oil into biodiesel? #317715伊藤 聡太郎MiembroSodium hydroxide (NaOH) and potassium hydroxide (KOH) are the most commonly used base catalysts for mustard oil biodiesel. The oil’s relatively low free fatty acid content usually allows for direct base-catalyzed transesterification without pre-treatment. The GlobeCore USB system is compatible with both catalysts and allows for fine-tuning dosage based on feedstock quality. Antioxidant additives can be used post-production to improve the stability of biodiesel made from high-erucic-acid oils like mustard.
伊藤 聡太郎MiembroConverting palm oil to diesel involves transesterification using alcohol and a catalyst. This creates fatty acid methyl esters—biodiesel—that can be used in diesel engines. For best results, the oil should be refined to reduce water and free fatty acids. The GlobeCore USB system ensures high-quality biodiesel output, with modules for heating, reaction, and separation built in. The process is fast, safe, and compliant with international biodiesel regulations.
abril 3, 2025 a las 10:38 pm en respuesta a: What equipment is needed for biodiesel production from rapeseed oil? #317381伊藤 聡太郎MiembroProducing biodiesel from rapeseed oil requires several key components: an oil press (to extract the oil), filtration units (to remove solids and impurities), a reactor for transesterification, and separation equipment for removing glycerin. Optional stages include methanol recovery and washing/drying of the final fuel. The GlobeCore USB biodiesel production plant integrates all essential stages except oil pressing, offering automated heating, mixing, reaction, and separation within one modular system. It is scalable, reliable, and engineered to deliver high yields with minimal labor, making it perfect for professional and industrial use.
marzo 24, 2025 a las 11:06 pm en respuesta a: How does precision-controlled rubber mixing equipment improve formulation accuracy? #316468伊藤 聡太郎MiembroThe USB 6 Impeller Stirrer features adjustable speed settings, automated process control, and real-time monitoring, ensuring accurate ingredient blending and formulation precision.
marzo 18, 2025 a las 8:25 pm en respuesta a: What industrial equipment is used in gypsum board production? #315711伊藤 聡太郎MiembroKey equipment includes mixers like the USB 6 Impeller Stirrer, which provides efficient and homogeneous slurry preparation.
伊藤 聡太郎MiembroA power factor test measures the phase difference between voltage and current in a dielectric material, indicating the level of energy loss and the quality of insulation.
伊藤 聡太郎MiembroCooling in transformers involves dissipating the heat generated during operation, often through natural convection or forced methods (using fans or pumps), with oil acting as the primary coolant.
伊藤 聡太郎MiembroTransformer oil specifications include parameters such as dielectric strength, flash point, viscosity, acidity, moisture content, and pour point, ensuring the oil performs safely and effectively.
marzo 7, 2025 a las 11:01 am en respuesta a: why nitrogen is filled in transformers during transportation #314656伊藤 聡太郎MiembroNitrogen is introduced into transformers during transportation to displace oxygen and moisture, thereby preventing oxidation and degradation of the oil and internal components, which helps maintain the transformer’s performance and prolong its service life.
伊藤 聡太郎MiembroTransformer oil is usually replaced according to manufacturer guidelines and condition-based monitoring; routine changes might be scheduled every five to ten years, but if oil testing reveals significant degradation, contamination, or moisture ingress, an earlier change is recommended.
伊藤 聡太郎MiembroTransformer oil is used primarily for insulation and cooling, helping to prevent electrical arcing and dissipate heat during operation.
febrero 25, 2025 a las 4:04 pm en respuesta a: What impact does effective grinding have on the visual appeal and color uniformity of spice mixtures? #313815伊藤 聡太郎MiembroEffective grinding ensures that color pigments are evenly distributed, resulting in a uniform, attractive appearance. The Colloid Mill GlobeCore produces a consistently milled spice powder that enhances the visual appeal and marketability of the final product.
