PROCEDURE FOR THE SET OF GP AND GI GAINS

Lead GP to the minimum

Open a small levy and give it small perturbations. While checking a manometer, increase GI as long as the first oscillations, due to the perturbations, start.

The GI gain to set is ¼ of the value that you have found at the previous step.

After have set GI, increase GP as long as the first oscillations start, and set GP at ¼ of the value that you have found during the first oscillations.

SINGLE-PHASE INVERTER WIRED ON A THREE-PHASE INE

An inverter without PFC* absorb an impulsive current in correspondene of the AC voltage’s picks. If more than one inverter are wired on a three-phase line distributing them on the three phases to balance the load, it creates a current imbalance on the neutral wire: the sum of the three currents doesn’t vanish because of the non-sinusoidal nature of the absorbtion, and the currents close themselves to the neutral.

The result is that you can find on the neutral the sum of the three phase currents.

*PFC: Power Factor Correction, it’s an active or passive electronic system inserted between the electrical distribution and an eletric/electhronic device. Normally it’s on the input stage, inside the device. It serves to see to the distribution a resistive sinusoidal current consumption by the device. It corrects the non-linear absorption (impulsive absorption or armonics’ presence).

Циркуляционные насосы от известного итальянского бренда DAB, которые представлены по ссылке, практически не нуждаются в обслуживании. Но для того, чтобы предотвратить неисправности разного рода нужно, придерживаться определенных правил эксплуатации:

• Насос  не должен работать в пустой системе.
• Устройство должно работать в допустимом рабочем диапазоне.
• В случае, если насос используется крайне редко, его нужно включать на 10 минут примерно раз в месяц.
• Температура перегоняемой жидкости не должна превышать допустимых пределов.

Техническое обслуживание насосов

Для стабильной и качественной работы насосов нужно следить за состоянием циркуляционных насосов. Техническое обслуживание устройств заключается в следующих манипуляциях:

• Нужно не допускать образование шумов и вибраций.
• Раз в полгода желательно проверять правильность работы устройств по его характеристикам.
• Желательно проверять отсутствие чрезмерного нагрева мотора.
• При необходимости смазывать резьбовую часть элементов.
• Следить за возможным образованием течи в местах соединений.

Возможные неисправности и способы их устранения

Несмотря на то что циркуляционные насосы DAB – это качественные и надежные устройства с длительным сроком эксплуатации, неисправности все же возможны. Среди наиболее распространенных нужно выделить следующие проблемы:

• Циркуляционный насос при включении работает не корректно: не крутится вал. Причиной такой неисправности может стать окисление вала или посторонний предмет, которые блокирует работу. Для устранения причин, нужно извлечь двигатель с валом и ротором и провернуть колесо рукой. Если же есть инородное тело – нужно его удалить и для предупреждения подобных ситуаций можно поставить фильтр.
• В случае если устройство полностью не включается нужно проверить питание и предохранитель, если он предусмотрен в модели.
• Устройство работает нестабильно: после включения и непродолжительной работы останавливается. Возможной причиной неисправности может являться наличие известкового отложения. Ремонт заключается в очистке системы от накипи. Для этого нужно демонтировать двигатель устройства.
• При включении насоса возникает сильный шум. Это возникает тогда, когда в отопительной системе образовалось скопление воздуха. Для решения этого вопроса достаточно спустить его при помощи специального клапана.
• Во время работы присутствует вибрация – требуется замена подшипника.

Стоит отметить, что все подобные неисправности с насосами DAB происходят только при неправильном техническом обслуживании или несоответствующей установке.

Для решения этих и других возможных проблем, лучше обращаться к специалистам, поскольку некачественный ремонт может привести к образованию более серьезных проблем в работе циркуляционных устройств DAB.
