------ WARNING! ------

机器突然动作,会导致人员伤亡。

机器突然移动,会对机上或机器近处的人员造成伤害。

为避免伤亡事故,开动机器之前,确保机器周围无人及没有各种障碍物。


------ WARNING! ------

滚热的油或液压油的压力会对人员造成伤害。

发动机停机之后,液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前,如果不事先释放压力,可能会造成严重伤害。

卸下机具和其油路之前,必须先把机具放到地面上,让油先冷却,才可进行工作。 只能在发动机停机,并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。



注意

在检查、保养、测试、调整及维修产品时,请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前,请准备好盛接液体用的适当容器。


运行检查

注: 朝每个方向并以所有档位运行机器。 注意异常噪音,然后找出噪音源。 如果机器工作异常,请参阅下面的故障和可能原因列表。

振动系统故障的可能原因

故障:振动系统不工作。

可能的原因

  • 泵驱动故障。

  • 控制台上的振动控制开关故障。

故障:振动系统的周期性损失。

可能的原因

  • 振动控制开关故障。

  • 电路接线中的连接松动。

故障:振动生硬挂档。

可能的原因

  • 振动安全压力设置过高。

故障:慢振动频率停机。

可能的原因

  • 主安全阀在环路的回流侧没有正确关闭。

故障:压实机没有达到最大振动频率。

可能的原因

  • 马达排量止动螺钉(固定频率)未正确调整。

  • 钢轮油位过高。

  • 发动机高怠速调整不正确。

  • 控制器电路(可变频率)控制器速度或接线故障。

  • 活塞泵或马达内部泄漏过大。

  • 振动轴承故障。

故障:振动机构噪声大。

可能的原因

  • 振动壳体中缺少润滑油。

  • 振动驱动轴或引向振动驱动轴的部件故障。

  • 振动马达的固定螺栓松动。

  • 振动轴承故障。

故障:液压回路油过热。

可能的原因

  • 液压系统中使用的油类型不正确。

  • 液压油冷却器阻塞。

  • 开式回路中内部泄漏过大。

  • 充油管路压力不足。

  • 振动轴轴承故障,导致振动泵高压溢流的时间过长。

故障:最大 VPM 过高。

可能的原因

  • 流量控制阀调整不当。

  • VPM 计故障。

  • 发动机转速过高。
