Тяговые батареи для техники

Что есть тяговые батареи

Тяговые аккумуляторы это аккумуляторные батареи, предназначенные для скопления и отдачи большого объёма энергии в течение долгого времени. Их главное назначение обеспечение питания электрических транспортных средств и спец техники, например:

- Электропогрузчики
- Электрокары
- Электроштабелёры
- Поломоечные, уборочные машины
- Гольфкары

В небольшом отличии от стартерных аккумуляторов, тяговые батареи рассчитаны на глубочайший разряд и многократные циклы зарядразряд.

Основные типы тяговых аккумуляторов

* Кислотные (сурьмянистые, малосурьмянистые)
Классическая разработка, проверенная годами. Отличаются низкой ценой, но требуют постоянного обслуживания.

* AGM и GEL
Модификации свинцово-кислотных аккумуляторов, где электролит находится в абсорбированной (AGM) или гелеобразной форме (GEL). Таки батареи не требуют обслуживания и безопаснее в эксплуатации.

* Литий-ионные
Современный вариант тяговых аккумов выше энергоёмкость, малый вес, резвое время заряда, не требуют техобслуживания, долгий срок службы. Минус высочайшая цена.

Преимущества использования тяговых аккумуляторов

- Возможность неоднократного циклирования заряда и разряда
- Высокая отдача энергии при условно малых габаритах
- Долговечность при правильной эксплуатации
- Безопасность (неподражаемо у герметизированных вариантов)
- Уменьшение расходов на горючее и обслуживание техники

На что направить внимание в момент выбора

1. Ёмкость аккумулятора (Ач) подбирается с запасом, исходя из употребления техники.
2. Тип аккумулятора наличие требований к обслуживанию, безопасность, рабочие условия.
3. Напряжение батареи должно соответствовать требованиям техники.
4. Размеры и форма соответствие батарейного отсека.
5. Репутация производителя по этой причине зависит качество и ресурс батареи http://zq505.com/home.php?mod=space&uid=49765&do=profile

Эксплуатация и сервис

- Соблюдайте инструкции по заряду и уровню.
- Не допускайте глубочайших разрядов (в особенности для свинцово-кислотных моделей).
- Для обслуживаемых АКБ регулярно проверяйте уровень электролита.
- Используйте только рекомендованные производителем зарядные устройства.
- Соблюдайте температурный режим хранения и использования.

Вывод

Правильно подобранные и эксплуатируемые тяговые батареи обеспечат бесперебойную работу вашей техники, минимизируют издержки на обслуживание и эксплуатацию, но также продлят срок эксплуатации оборудования. Большой выбор современных аккумов позволяет подобрать решение под любые задачи и бюджет.

Why there’s a huge collection of vintage cars stored in the middle of the desert

Back at the turn of the 21st century, Qatar was a country with few cultural attractions to keep visitors and residents entertained. Yet the Sheikh Faisal Bin Qassim Al Thani Museum — known as the FBQ Museum — was a place that most people visited as an alternative to the then-still rather ramshackle National Museum of Qatar.

You had to make an appointment, and drive out into the desert, getting lost a few times along the way, but then you were welcomed to the lush Al Samriya Farm with a cup of tea and some cake. The highlight was being allowed into a space crammed full with shelves and vitrines holding all sorts of eclectic artifacts from swords to coins — with the odd car and carriage standing in the grounds.

It wasn’t necessarily the kind of museum you’d find elsewhere in the world, but it was definitely a sight that needed seeing.

Today, it has grown and now claims to be one of the world’s largest private museums. It holds over 30,000 items, including a fleet of traditional dhow sailboats, and countless carpets. There’s also an entire house that once stood in Damascus, Syria.

There are archaeological finds dating to the Jurassic age, ancient copies of the Quran, a section that details the importance of pearling within Qatar’s history, and jewelry dating to the 17th century.

There are also items from 2022’s FIFA World Cup in Qatar including replica trophies, balls used in the games, entry passes, football jerseys and even shelves full of slightly creepy dolls and children’s plush animals.

Some of the more disturbing exhibits include various items of Third Reich paraphernalia in the wartime room, and, strangely enough, several showcases of birds’ legs with marking rings on them. Basically, whatever you can think of, you have a very good chance of finding it here.

Rumor even has it that behind a locked door is a room filled with the late Princess Diana’s dresses and other memorabilia, accessible only to a select few visitors. Another door hides a room, no longer open to the public, filled with collectibles of the late Saddam Hussein.

Some scientists believe that fatty acids such as decanoic acid and dodecanoic acid formed the membranes of the first simple cell-like structures on Earth, Pearce said.

“(This is) the closest we’ve come to detecting a major biomolecule-related signal — something potentially tied to membrane structure, which is a key feature of life,” Pearce said via email. “Organics on their own are intriguing, but not evidence of life. In contrast, biomolecules like membranes, amino acids, nucleotides, and sugars are central components of biology as we know it, and finding any of them would be groundbreaking (we haven’t yet).”
Returning samples from Mars
The European Space Agency plans to launch its ExoMars Rosalind Franklin rover to the red planet in 2028, and the robotic explorer will carry a complementary instrument to SAM. The rover LS6 will have the capability to drill up to 6.5 feet (2 meters) beneath the Martian surface — and perhaps find larger and better-preserved organic molecules.

While Curiosity’s samples can’t be studied on Earth, the Perseverance rover has actively been collecting samples from Jezero Crater, the site of an ancient lake and river delta, all with the intention of returning them to Earth in the 2030s via a complicated symphony of missions called Mars Sample Return.
Both rovers have detected a variety of organic carbon molecules in different regions on Mars, suggesting that organic carbon is common on the red planet, Williams said.

While Curiosity and Perseverance have proven they can detect organic matter, their instruments can’t definitively determine all the answers about their origins, said Dr. Ashley Murphy, postdoctoral research scientist at the Planetary Science Institute. Murphy, who along with Williams previously studied organics identified by Perseverance, was not involved in the new research.

“To appropriately probe the biosignature question, these samples require high-resolution and high-sensitivity analyses in terrestrial labs, which can be facilitated by the return of these samples to Earth,” Murphy said.

Siham Haleem, a private tour guide for 15 years, says that Doha now has many world-class, modern museums — the National Museum of Qatar being a firm personal favorite. And yet he says that visiting Sheikh Faisal’s museum should still be on everybody’s to-do list.

“For those eager to learn about Qatar’s — and the region’s — heritage and beyond, the museum is an ideal destination,” he says. “Personally, I’m captivated by the car collection, the fossils, and especially the Syrian house, painstakingly transported and reassembled piece by piece.”

Stephanie Y. Martinez, a Mexican-American student mobility manager at Texas A&M University in Qatar likes the museum so much she includes it on all of her itineraries for students visiting from the main campus in Texas.

“The guided tours are very detailed, and the collections found at the museum have great variety and so many stories to unfold,” she says. “Truly, the museum has something to pique everyone’s interest. My favorites are the cars and the furniture exhibits showcasing wood and mother-of-pearl details. Definitely one of my favorite museums in Qatar, every time I visit I learn something new.”

Raynor Abreu, from India, also had praise for the unusual and immense collection.

“Each item has its own story, making the visit even more interesting,” he says. “It’s also impressive to know that Sheikh Faisal started collecting these unique pieces when he was very young. Knowing this makes the museum even more special, as it reflects his lifelong passion for history and culture.”

It takes time and dedication to truly examine the many collections within the museum — especially since most of them are simply on display without explanation.

Eclectic it may be, but it’s hard to fault the determination of Sheikh Faisal, who has brought together items that tell the story of Qatar and the Middle East.

Sarah Bayley, from the UK, says she visited the museum recently with her family, including 16 and 19-year-old teenagers, and was won over by its sheer eccentricity.

“Amazing. Loved it. It is a crazy place.”
