Unic 370 ошибка е09

Манипуляторы UNIC

при работе без груза видвижение и собрание стрелы идет нормально, если под грузом то идет такая проблема, выдвигание норма, складывание, рычаг до упора, эффекта нет, дал газу, резкий сбор стрелы.

С уровнем масла ОК! Банка в сарае запасом лежит! Удочка 5 секционная 12 метров, 3 секции поршень, 2 на тросах, КМУ UNIC 360, на всех углах наклонах и вылетах с грузом, стрела на собрание ТУПИТ, насос родной и судя по стяжным шпилькам не разбирался, работает ровно без посторонних шумов, стрела сухая, заломов на удочке вроде не было, единственно смущает что у КМУ в свое время оборвали башню, фото пришлю. У меня второй грузовик MMC FUSO UNIC330, КМУ работает изумительно, мягко, ровно, на рычаги отзывается сразу без задержки, и скорость работы КМУ в 2 раза быстрее чем на NISSAN_е так что есть с чем сравнивать. Посоветуйте, пошаговый ремонт, с чего начнем решение этой проблемы?

андрей 0761, Как правило,именно на собрание стрелы и аутригеров-насосу требуется больше энергии- может и вправду он?

А он ни на чье схему не похож . . У тебя передача если без карданного вала ,сразу крепление на коробке отбора. Так> ? Вот та труба черная -это переходная муфта,сделано так для быстрого перехода с родных шлицов на русский насос ,сложного ничего-просто нужен умелец который выточит муфту и наколотит в ней шлицы-Японский-русский ,ну и + крепление. Качает здорово,правда есть еще там одна фишка-дренаж называется- это трубочка ,которую нужно вывести в бак-маслонаполнитель!

И надо сказать за свои деньги работают отлично . Справка — Русский насос НШ-3… и далее стоят 1-1,5 рубля. Так чта насос -это дело сугубо по подходу ,

андрей 0761, Не лазил-дома уже. Машины у нас одинаковые и ручник у меня тоже близко. Данные спишу. Если нужно сильно ,у товарища есть насос японческий- у него Камаз-стрелу брал в Москве,а так как насос не сгодился,то лежит- но ценник он знает . так что рублей 20 будет думаю. Вот что мне не нравится в Б/У приобретении- так это состояние которого не знаешь-
По поводу быстроты работы стрелы- не всегда это нужно,мало того что работа часовая,так еще точность приземления важна ,а когда башню мотыляет как потерпевшую и плавность поймать не в силах-тоже не гуд!

У меня стоит аксиально-поршневой на 32 л/мин . Скорость вращения как и всех,на газульку давлю, просто он тянет до последнего на холостых, не срывается как НШ японский.. На пальцах попробую еще раз — Если на японском вы берете груз ,который превысил допустимый,а сначала берете стрелой,но стрела не тянет, а лебедка все еще тянет,то этот груз лучше не брать,, У мну же пофигу- берет все,так как поршни давят масло и им пофиг, Вот поэтому работаю с осторожностью.!
андрей 0761 — у тебя японский тоже НШ, -насос шестеренчатый, поэтому все так же как и было,так и будет, просто меньше 32 лмин ставить не надо ,а если есть ,то поставь лучше 52 или 51 -точ.не помню, -будет побыстрее, но быстрота ,кстати не всегда гуд,

поставили НШ 32 левый, в итоге вместе со шлангами и всеми затратами 11к рублей, думаю приемлемо, посмотрим как будет себя вести в последствии

Возвращаясь к началу, скажу, если какое-то одно действие выполняется с трудом, например задвижение стрелы, то возможно попадание куска резины от порванного манжета в гидрозамок цилиндра… У меня такое было на главном цилиндре подёма стрелы…
И ещё : когда тяните груз гидравликой, то там стоит ограничитель давления (болтик под металлическим колпачком позади распределителя) и он не дает поднять больше заданной массы, и это не зависит от типа насоса, поршневой или шестярёнчатый, крутить не советую, также как и рвать груз лебёдкой, дабы не загнуть стрелу… гидравлика не даст поднять больше чем может позволить себе установка…

DIESEL, Я у тебя про него и спрашивал. , только крутить его можно ,даже в наших условиях. . Просто нужно взять эталонный груз- например тонны в 2,5 на вылете соответствующем показаниям стрелочки на самой удочке. И тянуть стрелой,соответственно подкручивая перепускной. как тянуть перестает-можно остановит момент. У меня лично иголка выработалась и клапан закручен до попы,что особо не мешает машине работать,но напрягает медленная работа всего механизма. Думаю этот клапан влияет и на скорость

C 3-м вообще проблем нет, это пробка уровня масла редуктора, ее перед началом ремонта открутишь , масло сольешь, по окончании ремонта через открученный сапун зальешь новое масло (у меня ТАД-17) пробку посади на фум ленту.
