Efficient clearing operations
since 1950
The story of Giletta
Founded in 1950, Giletta started its operations as a distributor of agricultural machinery. In the years immediately following, the company started as a production company of hay elevators, fertiliser spreaders, and manure spreaders. In 1966, according to a request of a private contractor that carrying out snow clearing operations on the provincial road, Giletta designed a sand and salt spreader. The spreader had a double feed chain, which was the technology used in the production of agricultural machines and had a capacity of 11 cubic metres, suitable for a 6×4 truck. At that time, the largest spreader in Europe was 6 cubic metres, and therefore the new machine represented a great novelty on the market for which the first highways, in order to reduce the number of vehicles, started to buy the new spreader. Thus began the first diversification, from a manufacturer of agricultural machinery to a manufacturer of winter maintenance equipment.
Defined by innovation
Working closely with the customers, attention to details and quality has defined Giletta as one of the most innovative manufacturers in the industry. In 1976, with the introduction of the electronic control of the amount of salt spread based on the speed of the vehicle, Giletta enabled customers to control the amount of material spread. In 1978, the 15 cubic meters spreader was launched and already in 1980, Giletta introduced the first chloride spreader with the pre-wetting system, representing a revolution in winter maintenance due to the significantly lowered risk of accidents.
In 1989, the first fully modular spreader was patented and further steps were taken for digital control of spreading operations with the Ecosat microprocessor. The fully automated satellite control of chloride spreading operations dates back to 1998. In 1999, at the request of the largest Italian motorway company managing in real-time a significant amount of snow-clearing vehicles on the Apennine mountain motorway, the first digital system for tracking and remote control of winter operations was developed.
A Bucher company
In 2002, Giletta joined Bucher Municipal group and made its entry into high-potential markets. In order to complete the range of products and to offer the various markets a full set-up of the vehicles for winter roads, SnowTec, a French manufacturer of innovative snow ploughs, was acquired in 2003. In the acquisition, Bucher Municipal also took over Arvel, the Giletta-owned distributor founded in 1997 responsible for sales and service of winter maintenance equipment in France.
In 2005, the new Bucher UniQa spreader was introduced and the modularisation of production was fully implemented with robotic welding, double-layer powder coating, epoxy with high zinc content, and polyester as well as assembly lines for all products. Furthermore, in 2009, the company invested in Saet, a company specialised in the design and production of electronic controls and related wiring, in order to increase the know-how in all electronic devices for the further strengthening of intelligent products.
Multiple brands and multiple applications
The growth of the Bucher Municipal winter maintenance portfolio continues with the acquisition of the Spanish distributor Maquiafalt in 2011, and in 2012 with the acquisition of Assaloni.com, a historic manufacturer of snow clearing equipment, famous all over the world above all for the patented telescopic snow ploughs. In 2014, the Kaluga production facility in Russia was opened, built for the production of all the equipment destined for this important market, some of which were specifically designed for extreme working conditions in the region.
Ошибки частотных преобразователей: примеры и коды ошибок
Частотные преобразователи — это электронные или электротехнические устройства, предназначенные для изменения и регулировки частоты электрического напряжения. Сфера их использования очень широка: насосные станции, системы тепло- и водоснабжения, линии производства, конвейеры, лифты, центрифуги, мельницы, металлургические агрегаты, буровое оборудование и т. д.
Использование частотных преобразователей на промышленных объектах дает следующие преимущества:
- Возможность отказаться от регулирующего оборудования: дросселей, вариаторов, редукторов и др. Это существенно упрощает работу механической системы, снижает расходы на эксплуатацию и повышает ее надежность.
- Плавный разгон управляемого двигателя, защищающий его от механических ударов и пусковых токов, что продлевает срок его службы.
- Частотные преобразователи в паре с асинхронными двигателями можно использовать в качестве альтернативы для приводов постоянного тока.
- Максимально рациональное регулирование скорости контролируемых двигателей и связанных с этим технологических процедур.
- Экономия электроэнергии, благодаря устранению ее неоправданных трат.
Но, несмотря на свою надежность и эффективность, частотные преобразователи, как и любые электронные приборы, подвержены износу. Инженерная компания 555 специализируется на ремонте промышленной электроники, и в частности — на устранении ошибок частотных преобразователей. Наши специалисты готовы отремонтировать вышедшее из строя оборудование в кратчайшие сроки.
Основные виды и причины неисправностей
Опознать неисправности частотников позволяют коды ошибок, высвечивающиеся на мониторе устройства. Каждая такая комбинация символов указывает на совершенно конкретную проблему, и это помогает специалистам выработать правильную стратегию ремонта. Для начала рассмотрим типовые виды ошибок частотных преобразователей:
- Over Current или OC. Данный сигнал на мониторе устройства свидетельствует о его перегрузке. Если подобная проблема возникла при тестовом запуске, необходимо проверить соответствие токов регулятора и электрической машины, а также исправность электроцепей управляемого двигателя. Следует учесть, что некоторые модели частотников высвечивают ошибку Over Current при торможении, работе и запуске электродвигателя.
- Over Heat или ОН. Это сообщение указывает на превышение номинально допустимой температуры частотного преобразователя. Проще говоря — на его перегрев. Устранить проблему можно посредством чистки внутреннего вентилятора или установки дополнительной вентиляционной системы в бокс, где располагается преобразователь. В качестве профилактики следует размещать частотник в месте, гарантирующем эффективный отвод тепла.
- Over Load или OL. Такая ошибка преобразователя может быть вызвана двумя обстоятельствами: превышением на валу момента силы или перегревом управляемого двигателя. Чтобы устранить проблему, необходимо выполнить корректную настройку тепловой защиты. Для этого во время программирования устройства нужно задать требуемую величину тока и время срабатывания защитной функции.
- Low Voltage или LV. Ошибка высвечивается при снижении напряжения питания или обрыве фаз (одной или двух). Существует два варианта решения этой проблемы: «насильственная» остановка двигателя или настройка его работы в однофазном режиме.
- Over Voltage или OV. Такую надпись можно увидеть на мониторе при замедлении вращения двигателя. Для устранения неисправности необходимо воспользоваться одним из трех способов: переводом устройства в режим генератора, активацией тормозного резистора или перенастройкой системы защиты от повышенного напряжения.
Среди других типовых неисправностей преобразователя следует выделить вращение двигателя в неправильном направлении, невозможность его запуска, проблемы с торможением и разгоном и т. д. Каждое повреждение имеет под собой конкретные причины. Например, если двигатель разгоняется очень медленно, скорее всего, дело в срабатывании функции токоограничения в момент разгона.
В число наиболее распространенных причин неисправностей входят:
- Заводской брак. Как правило, фабричные дефекты дают о себе знать в течение гарантийного срока. Поэтому для их устранения следует обращаться к поставщику или в брендовый сервисный центр.
- Ошибки при монтаже. Чаще всего причиной неисправностей становится некорректная сборка схемы привода или установка частотника в неподходящем месте.
- Нарушение норм эксплуатации. Регламент технического обслуживания изложен в инструкции, прилагаемой к устройству. Игнорирование регламента может привести к выходу из строя полупроводниковых элементов, перегреванию частотного регулятора и другим неисправностям.
- Несоответствие частотного преобразователя условиям его эксплуатации. Основные критерии выбора частотника — электрические характеристики двигателя, исполнение, набор функций и т. д. Несоответствие параметров условиям его эксплуатации приводит к некорректной работе устройства, выходу из строя и многочисленным поломкам.
Теперь поговорим об ошибках преобразователя частоты более подробно и предметно. В качестве примера рассмотрим привод известного китайского бренда INVT ELECTRIC CO, серии GDXXX.
