●防爆标志为: Exd IMb,适用于煤矿带式输送机用及矿井提升设备等用电力液压鼓式制动器和电力液压盘式制动器用的电力液压推动器。
STANDARDS COMPLIANT
●Explosion protected electro-hydraulic thruster meet GB3836 -2010, JB/T 10603 - 2006 and enterprise standard Q/ZYBC01 -2019.

●Explosion-proof mark is "ExaIMb".

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。
●油缸壳体在一侧设有平衡气室,可使推动器在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-oill 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 of 0~ 180° and enlarge the using range .

●All saling parts and bearing are all world famous products. The sealing is reliable and durable.

附加装置 ADDITIONAL DEVICES


●UL-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,但不得超过内置弹簧力(见参数表);
●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 falling time, delay range is from 5s to 30s,specific delay time can be set as customers' requirements.

BEd系列隔爆推动器技术参数 TECHNICAL DATA OF BEd SERIES EXPLOSION PROTECTED ELECTRO-HYDRAUUC THRUSTERS



BEd系列隔爆型推动器技术参数-表1
●注:内置弹簧力是推动器推动额定行程1/3时的力。Note: Build-in spring force equals the force the thruster applying to 1/3 of rated stroke.
●当推进器内置装弹簧时,输出推力为零。When springs listed in above tables are equipped in thruster, output thrust is zero.

●隔爆型推动器有三个电缆引入装置位置(如图所示,电缆引入装置标准设在右侧),需注明可任选一位置安装。There are three cable entry positions for explosion protection electro-hydraulic thruster (shown as the figure, cable entry position is on the right by standard), the customers can selet any position freely.

安装方式 MOUNTING


●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。如图所示:

●The foot lugs can be installed around 90° ( please indicate at order ), head of thruster can turn freely around 360°,all thrusters can be installed perpendicularly or horizontally, angularity( < 15° or> 15°),The balancing air house should be set upward.
