March 27, 2026 at 6:45 pm in reply to: What unit can be used for purification of industrial oils with water and solid contamination? #342313Maria FernandezMember
A CMM-6/7 oil purification unit is a suitable choice. It performs filtration, dehydration, and degassing in one process, ensuring stable oil quality.
March 27, 2026 at 5:26 pm in reply to: What device is used to measure the breakdown voltage of transformer oil? #342305Maria FernandezMemberThe TOR-80 breakdown voltage tester is used for this purpose. It provides fully automated and accurate measurement of dielectric strength up to 80 kV according to international standards.
March 16, 2026 at 7:27 am in reply to: How is a marine fuel oil polisher different from other systems? #342010Maria FernandezMemberYou’re right — continuous recirculation is a core differentiator for marine fuel oil polishers. Rather than a one‑time pass through a filter, marine polishers draw fuel from the storage tank and pass it repeatedly through multi‑stage treatment (mechanical separation, adsorption columns and water removal) before returning it to the tank, so contaminants from water ingress, microbial growth and sediment are reduced gradually and the tank’s overall fuel quality is stabilized over time. That steady polishing lowers the risk of clogged day tanks and engine filters, reduces unplanned engine shutdowns and keeps viscosity and combustion properties more consistent during long voyages or extended storage.
On top of continuous circulation, marine polishers typically use adsorbent columns (not just media or cartridge filters), allow in‑place reactivation of sorbent for many reuse cycles, and include automatic polishing/regeneration cycles and instrumentation for tank connections and visual monitoring. They can remove particulates, entrained water and even environmentally undesirable contaminants such as sulfur compounds and hydrogen sulfide in heavy fuels, and best practice is to pair polishing with pre‑treatment for coarse solids and bulk water removal to maximize throughput and adsorbent life. Models designed for low‑viscosity marine fuels reach practical capacities (for example around 45 m3/h) and operate on three‑phase supply with modest power draw, so they’re sized for continuous service aboard ship rather than occasional filtration.
February 24, 2026 at 8:44 am in reply to: How does the Colloid Mill GlobeCore contribute to the homogenization of peanut butter? #333949Maria FernandezMemberПовністю згоден з вашими зауваженнями — тепло, що генерується при інтенсивному високошвидкісному зсуві в роторово-статорних системах, прямо впливає на смак, аромат і стабільність арахісової пасти. У конструкції CLM-100.2 саме ротoр/статор з каналами й регульованими зазорами (осьовий 0,2–2 мм, радіальний ~0,25 мм) і робочою швидкістю ножів до ~50 м/с створюють високі зсувні напруження для подрібнення і емульгування олій, але це ж джерело тепла. При роботі важливо контролювати температуру продукту і тривалість перебування в зоні обробки: краще досягати бажаного розміру часток і однорідної реології через оптимізацію зазору, швидкості та кількості проходів, ніж продовжувати один інтенсивний пропуск, який може викликати деградацію смакових сполук і підвищити ризик розшарування олії. Характеристики апарата (продуктивність приблизно 0,1–1 м3/год, робочий об’єм ~5 л, максимальна робоча температура до 180 °C для серії) дають можливість налагодити режим під різні рецептури, але в стандартній практиці бажано підтримувати якомога нижчу робочу температуру і мінімізувати нагрівання.
Інтеграція млина в технологічний ланцюг — ключ до стабільності: передмелення, контроль подачі (стабільний подачний насос або гравітація), рівномірний витрата і можливість рециркуляції дозволяють зберегти константну реологію та цільовий розмір часток (для кремоподібної пасти промислова мета — дрібні частки на рівні декількох десятків мікрон). Якщо потрібно — використовують охолоджувальні манжети або вбудовані теплообмінники/теплосистеми (деякі моделі мають масляне опалення для протилежних завдань), а також термопари та моніторинг температури на вході/виході для запобігання перегріву. Практична порада: налаштуйте режими на пробній серії, фіксуйте зазор і швидкість ножів, стежте за температурою й в’язкістю продукту; якщо потрібно більша однорідність — робіть кілька коротких проходів із охолодженням між ними замість одного тривалого пропуску. Це забезпечить стабільну гомогенізацію, мінімізує ризик розшарування олії та збереже смакові і поживні властивості.
January 27, 2026 at 2:38 pm in reply to: What is the role of a transformer at an electrical power station? #332269Maria FernandezMemberStep-up for transmission efficiency, auxiliary feeds, and grid interface functions.
January 26, 2026 at 4:57 am in reply to: which of these does a transformer change voltage current energy power? #331975Maria FernandezMemberA transformer changes voltage and current levels while transferring energy from one circuit to another through electromagnetic induction. It does not create energy or power; instead, it shifts the voltage/current ratio so that the apparent input power is approximately equal to the output power, minus real-world losses.
January 24, 2026 at 11:03 am in reply to: How is the power rating of a transformer calculated? #331655Maria FernandezMemberSame method, with PF-independent apparent power guiding specification.
January 23, 2026 at 3:15 pm in reply to: What do power transformer pictures reveal about construction and cooling? #331492Maria FernandezMemberPictures reveal whether the transformer is oil-filled or dry-type, the number and arrangement of radiators or cooling fins, presence of fans or pumps, and whether there is a conservator tank or sealed tank design. Bushing size and geometry hint at voltage levels, while OLTC compartments and cable boxes show connection types. Placement of temperature gauges, oil level indicators, and monitoring sensors can also be seen, giving clues about how cooling and condition monitoring are implemented.
January 22, 2026 at 8:51 am in reply to: What typical reduction in moisture content can be achieved with the CMM-12R oil regeneration systems? #331213Maria FernandezMemberThe moisture content in oil can be reduced significantly, often from the tens of ppm range down to single-digit ppm levels, enhancing dielectric performance and reducing the risk of hydrolysis.
January 22, 2026 at 2:35 am in reply to: What documentation or training is typically provided with the CMM-G? #331123Maria FernandezMemberWhile the webinar would detail operation and safety training, the unit typically comes with comprehensive manuals, on-site commissioning support, and operational training for technicians to ensure correct use of modes, maintenance planning, and safe handling of pressurized fluids.
January 21, 2026 at 11:05 am in reply to: Will the TOR-5 online monitoring system help improve DGA parameters if they increase during operation? #330876Maria FernandezMemberIn practice, TOR-5 can help stabilize or slow down the growth of some DGA parameters, but it is not a direct “gas treatment” system. By continuously drying the oil and limiting moisture-driven aging, it reduces hydrolytic reactions and secondary gas generation over time. This often leads to slower hydrogen growth and more stable trends. However, if DGA increases are caused by an active electrical or thermal fault, TOR-5 will not eliminate it – it will only help you detect it early and prevent secondary degradation.
January 19, 2026 at 8:50 pm in reply to: Why do power transformers require specific power cable ratings? #330404Maria FernandezMemberCable ratings must match kV class, ampacity, short-circuit withstand, and thermal characteristics to ensure safe operation and compliance with grid standards.

September 17, 2025 at 2:10 pm in reply to: How does a transformer oil filtration system work? #325607Maria FernandezMemberIt heats oil, removes solid impurities, then applies vacuum dehydration and degassing. GlobeCore’s systems automate this – restoring BDV, removing acids, and bringing oil back to IEC 60422-compliant condition.
September 17, 2025 at 12:13 pm in reply to: What is the correct transformer vacuum oil filling procedure? #325584Maria FernandezMemberOil is dehydrated and degassed, then filled under vacuum to prevent moisture absorption. GlobeCore equipment automates this procedure – ensuring the oil enters the transformer with <10 ppm moisture and no entrapped gases.
September 10, 2025 at 1:15 pm in reply to: What does dry type transformer maintenance require? #325222Maria FernandezMemberDry transformers don’t use oil but still require dust removal, thermal inspections, and thermal cycling checks. GlobeCore focuses on oil-filled units but offers tools to monitor oil-free systems as part of predictive maintenance plans.
