主要特點 MAIN FEATURE


●電機為非浸油式結構,F級絕緣,耐熱性好,壽命長。

●電機軸和推桿均表面特殊處理,使密封件壽命大大延長。
●油缸殼體在-側設有平衡氣室,可使防爆型推動器在0-180°任何方向安裝,從而擴大其使用范圍。
●全部密封件和軸承采用世界名牌產品,密封可靠,壽命長。
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.

附加裝置 ADDITIONAL DEVICES


●∪L-上升限位開關,可指示制動器是否打開,推桿是否推到規定位置信息;

●DL-下降限位開關,可指示制動器是否正確閉合,推桿是否回到規定位置信息,可同時設置上下限位開關;
●C-增設內置式彈簧(僅短行程推動器可以),彈簧力可由用戶確定,但不得超過額定推力;
●H-上升延時閥和S-下降延時閥,可無級延長上升或下降時間,延時范圍為5秒至30秒,具體延時值可根據用戶要求調定。
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.
