18、e hydraulic power unit consists of an electric motor, a spur gear pump and a control valve block. The hydraulic power unit can be removed completely from the grab by removing the mounting bolts. The low mounting position of the hydraulic unit within the grab makes a low grab profile possible and fav

19、orable center of gravity.液压泵马达作为一个完整组件垂直地安装在斗框上,同时也有保护作用的功能。斗框的下半部同时也是油箱。液压动力装置由一个电动马达、一个直齿齿轮泵及一个控制阀模块组成。只要卸下固定螺栓,可以将液压动力装置从抓斗上折下。液压装置放在抓斗下部得到一个抓斗低位配置及最好的重力中心。The fixing points for the hydraulic cylinders are positioned at the frame and at the jaws. The jaws are opened and closed by retracting or ex

The hydraulic cylinders are protected against mechanical damage.液压缸的固定点处在斗框及抓爪上。通过控制活塞杆的来回运动,就可以开启或闭合抓爪。活塞杆经渡铬硬化。控制阀模块用液压管连接到液压缸上

21、。液压缸应作保护,避免机械损坏。Power is supplied to the electric motor via a rubber-coated cable and a plug unit. A strain relief feature is installed to protect the plug unit from damage. The plug is provided with a protective cover. 动力通过橡胶绝缘涂层电缆和插头供给电动马达。插头具有应变释放功能,能有效防止机械损坏。插头还同时提供保护盖。The grab is suspended with

25、 of the hydraulic system is so called open circulation with directional valve. Electric motor runs constantly during normal operation, but it will stop automatically in 30 seconds, if no open/close command is given (PLC setting). This system decreases number of motor start-ups and thus prevents high

26、 starting current damaging components. Hydraulic system automatically switches to free flow circulation in both directions. Thus no extra heat is produced. Observe! Directional valve controlled grab cant be operated without PLC-control command from crane.液压系统的类型属于称之为带导向阀的开放和循环型。电动马达在正常工作状态下持续运转,但如果无

27、开通/关闭的指令时, 它将在 30 秒内自动停止(程序逻辑控制设置)。这种系统减少了机器启动时马达的数量,因而有效地防止了启动时的大电流对部件的损坏。液压系统能在两个方向上自动地转换到自由流动循环状态。这样就不会产生过多的热量。 注意:由导向阀控制的抓斗如没有从起重机给出的 PLC 控制指令则不能工作。Free-flow circulation 自由流动循环Valve 阀 14 16.1 16.2 20Position 位置 Open 开 Closed 关 Closed 关 12When the electric motor is running the hydraulic pump pump

Cylinders keep their positions because counterbalance valves 18 and 19 and also check valves 17.1 and 17.2 are clo

29、sed.当电动马达驱动液压泵将油泵入流程图中的 P 点时,阀门 14, 16.1, 16.2 和 20 处在正常位置。 压力打开压敏阀门 15, 液压油通过它流回油箱 T3。液压缸保持它们的位置,这是因为平衡阀 18 和 19平以及截止阀 17.1 和 17.2 都有关闭着。Opening 打开Valve 阀 14 16.1 16.2 20Position 位置 Closed 关 Closed 关 Open 开 12The hydraulic fluid flows through valve 16.2 via point B to the rod side of the cylinder.

30、Pressure also opens the counter balance valve 18 and thus allows return flow from cylinder piston side via point A to the tank T3. When cylinder reaches the end position, increased pressure opens pressure control valve 13 and the system switches to free flow circulation.液压油流过阀 16.2 的 B 点到达液压缸杆。压力打开平
