主要特点 MAIN FEATURE


●电机为非浸油式结构,F级绝缘,耐热性好,寿命长。

●电机轴和推杆均表面特殊处理,使密封件寿命大大延长。
●油缸壳体在-侧设有平衡气室,可使防爆型推动器在0-180°任何方向安装,从而扩大其使用范围。
●全部密封件和轴承采用世界名牌产品,密封可靠,寿命长。
MAIN FEATURE
●Electrical motor is of non-under-oil structure, F grade insulation, durable and good heat resistance.
●The surface of motor axle and pusher is handled specially to make the sealing parts much more durable.
●Balancing air house is set at one side of oil cylinder casing, which can make the thruster to be installed at any direction within range of0~180° and enlarge the using range.
●All sealing parts and bearing are all world famous products.The sealing is reliable and durable.

附加装置 ADDITIONAL DEVICES


●∪L-上升限位开关,可指示制动器是否打开,推杆是否推到规定位置信息;

●DL-下降限位开关,可指示制动器是否正确闭合,推杆是否回到规定位置信息,可同时设置上下限位开关;
●C-增设内置式弹簧(仅短行程推动器可以),弹簧力可由用户确定,但不得超过额定推力;
●H-上升延时阀和S-下降延时阀,可无级延长上升或下降时间,延时范围为5秒至30秒,具体延时值可根据用户要求调定。
ADDITIONAL DEVICES
●Up limit switch; which can indicate whether brake is open, or whether the thruster is at the right position.
●Down limit switch, which can indicate whether the brake is properly close,whether the thruster return to right position. Up and down limit switches can be set together.
●Build-in spring or release spring (only for short stroke thruster). Spring force can be decided by customers, but within the force limit of built-in spring (refer to parameter tables).
●Ascending time -delay valve, descending time -delay valve or ascending/descending time-delay valve can steplessly prolong the rising and flling time , delay range is from 5s to 30s,specific delay time can be set as customers' requirements.

安装方式 MOUNTING


安装方式图


●底座均可旋转90°安装(用户在订货时注明),连杆头可360°任意旋转,全部推动器可垂直,倾斜(15°)安装,也可大于15°倾斜或水平安装,但平衡气室应朝上。如下图所示:
MOUNTING
