HYDAC蓄能器使用说明|HYDAC（苏州）分公司
HYDAC蓄能器在使用过程中防泄漏，要定期对气囊进行气密性检查及其他方面的检查。因此，日常检查与维护保养不可少。日常检查即用目视、听觉和手摸及仪表等简单的方法进行外观及状态的检查，检查时既要检查局部也要注意设备整体。在检查中发现的异常情况，对妨碍蓄能器继续工作的应作应急处理；对其他的则应仔细雨观察并记录，到定期维护时予以解决。一些损坏的零部件也需要及时更换。主动维护是继故障维修、预防维修、状态维修后，上近几年来提出的一种新的设备管理理论。
HYDAC蓄能器一直是上海威斯特热销产品，*低，质量保证。
HYDAC蓄能器使用维修说明：
HYDAC蓄能器的使用维修主要包括蓄能器的安装维护、故障诊断与排除及修理等。
HYDAC蓄能器的安装包括安装前的检查、安装、充氮等。正确的安装固定与充气，是HYDAC蓄能器正常运行、发挥应有作用的重要条件。参数的测量与各类工具仪表的正确使用不可忽略。
它的定义是：对导致设备损坏的根源性参数进行修复，从而有效地防止失效的发生，延长设备的使用寿命。主动维护是在设备磨损之前针对其根源问题采取的措施，有效地控制磨损及失效的发生，从而大幅度地延长修理周期。主动维护不但为液压设备与元件可造运行提供保障，同时可大幅度降低维修成本
德国HYDAC公司主要生产各种液压附件、系统等产品，广泛应用于冶金、造船、航空、造纸、电力、化工、机床及工程机械、建筑机械等领域。需求量逐年递增，市场不断扩大，已成为国内外的液压附件及各种液压装置的外资生产企业，赢得广大用户的信任和支持，已在北京、鞍山、武汉等地设立办事处.
HYDAC蓄能器是液压气动系统中的一种能量储蓄装置。它在适当的时机将系统中的能量转变为压缩能或位能储存起来，当系统需要时，又将压缩能或位能转变为液压或气压等能而释放出来，重新补供给系统。当系统瞬间压力增大时，它可以吸收这部分的能量，以保证整个系统压力正常。
液压油是不可压缩液体，因此利用液压油是无法蓄积压力能的，必须依靠其他介质来转换、蓄积压力能。例如，利用气体（氮气）的可压缩性质研制的皮囊式充气HYDAC蓄能器就是一种蓄积液压油的装置。皮囊式蓄能器由油液部分和带有气密封件的气体部分组成，位于皮囊周围的油液与油液回路接通。当压力升高时油液进入蓄能器，气体被压缩，直到系统管路压力不再上升；当管路压力下降时压缩空气膨胀，将油液压入回路，从而减缓管路压力的下降。

HYDAC蓄能器有两种用途。①当低速运动时载荷需要的流量小于液压泵流量，液压泵多余的流量储入蓄能器，当载荷要求流量大于液压泵流量时，液体从蓄能器放出来，以补液压泵流量之不足。②当停机但仍需维持一定压力时，可以停止液压泵而由蓄能器补偿系统的泄漏，以保持系统的压力。
蓄能器也可用来吸收液压泵的压力脉动或吸收系统中产生的液压冲击压力。HYDAC蓄能器中的压力可以用压缩气体、重锤或弹簧来产生，相应地蓄能器分为气体式、重锤式和弹簧式。气体式蓄能器中的气体与液体直接接触者，称为接触式，其结构简单，容量大，但液体中容易混入气体，常用于水压机上。气体与液体不接触的称为隔离式，常用皮囊和隔膜来隔离，皮囊体积变化量大，隔膜体积变化量小，常用于吸收压力脉动。重锤式容量较大，常用于轧机等系统中，供蓄能用。
HYDAC蓄能器在液压系统中属于危险部件，所以在操作过程中要特别注意安全。
HYDAC蓄能器故障诊断与排除，既包括蓄能器本身故障的诊断与排除，又涉及HYDAC蓄能器所在液压系统的故障诊断与排除，两者之间相互交织。故障诊断的主要工作内容有：①判定故障的性质与严重程度。根据现场状况，判断是否存在故障，HYDAC蓄能器是什么性质的问题（压力、速度、动作还是其他），问题的严重程度（正常、轻微故障、一般故障、还是严重故障）。②查找失效元件及失效位置。根据症状及相关信息，找出故障点，以便进一步排除故障，这里主要弄清“问题出在何处”。③进一步查找引起故障的初始原因。如液压油污染，元件可靠性低，环境因素不合要求等。这里主要弄清故障的外部原因。④机理分析。对故障的因果关系链进行深入地分析与探讨，弄清问题产生的来龙去脉。⑤预测故障发展趋向。根据系统磨损劣化的现状及速度、元件使用寿命的理论与经验数据，预测HYDAC蓄能器或液压系统将来的状况。分析、对比、统计、归纳与综合，找出规律。
