應 用
的，結構非常緊湊的驅動控制裝置，被廣泛用作各種塊式制
動器和盤式制動器的驅動裝置，還可用于各種工業閥門，閘
門，定向擺動和轉動(<90°)裝置(機構)及夾緊裝置的驅
動控制。
設計特點
●外殼為鑄造鋁合金，重量輕，外形美觀。
●電機為非浸油式結構,Ｂ級或F級絕緣(根據用戶要求),
耐熱性好，壽命長。
●電機接線盒蓋設有密封，采用電纜填料函進線，牢固
可靠，電氣外殼防護等級達IP55。
●電機軸和推桿均表面鍍硬鉻處理，使密封件壽命大大延長。
●油缸殼體在一側設有平衡氣室(MYT2-10/2.5除外),可使
推動器在0~180°任何方向安裝，從而擴大其使用范圍。
●Ed系列全部密封件和軸承采用世界名牌產品，密封可
靠，壽命長。
●Ed系列緊固件為不銹鋼材質，美觀耐用。
附加裝置
●上位限位開關：可指示制動器是否打開，推桿是否推
到規定位置等信息。
●下位限位開關：可指示制動器是否正確閉合，推桿是
否回到規定位置等信息，可同時設置上下限位開關。
●增設內置式制動彈簧或復位彈簧(僅短行程推動器可以)
復位彈簧力可由用戶確定，但不得超過內置制動彈簧力
(見參數表)。
●增設加熱器：在使用地點環境溫度低于-25℃時，如用
戶需要，可增設加熱器，加熱器參數見附表1。
●上升延時和下降延時閥或上升下降延時閥(MYT2-
10/2.5、YTD220-50、Ed220-50不能增設)，可無級延
長上升或下降時間,延時范圍為額定動作時間至30秒,具
體延時值可根據用戶要求調定。

Application
Electro-hydraulic thruster is a kind of drive control system, which
very compact in structure, integrates electrical motor, centrifugal pump
and oil cylinder. It is extensively used as drive mechanism of various
drum and disc brakes, drive control of various industrial valves,
penstock, directional pendulum andsteering(<90°) mechanism, and
as drive control of holing devices as well.
Design features
●The casing is made of casting aluminum alloy, light and beautiful.
●Electrical motor is of non-under-oil structure, B grade or F grade
insulation (upon customer's requirerment), good heat enderance and
long life.
●Cover of terminal box is sealed tight. Inlet is of cable stuffing
box style, firm and reliable. Electrical protection of casing reaches
IP55 grade.
●Both electrical motor shaft and thruster are hard chrome plated on
the surface making life of sealing parts greatly prolonged.
●Balancing air house is arranged at one side of oil cylinder casing
(with exception of MYT2-10/2.5). Thruster can be installed at any
direction within range of 0~180°, thus enlarging its scope of usage.
●All sealing parts and bearing of Ed series are of world known
products. The sealing is reliable and performance life is long.
●Fastening parts of Ed series are of stainless steel, beautiful and
durable.
Additional Equipment
All thrusters can realize some additional functions after equipped
with additional devices.
●Up limit switch can indicate such information as whether brake is
open, whether the thruster is in the right position.
●Down limit switch can indicate whether the brake is properly close,
whether the thruster return to right position. Upper and lower limit
switchs can be arranged simultaneously.
●Add built-in brake spring or release spring (only for short stroke
thruster), release spring can be decided by customers, but the force
of built-in spring can not be exceeded (see parameter tables).
●Add heater: in the place where ambient temperature is below-25℃,
heaters can be added upon customer's requirement. Parameters of
heaters are attached.(Tab.1)
●Delay valve of lift and delay valve of fall or delay of lift/fall valves
(delay valves can not be added for (MYT2-10/2.5、YTD220-50、
Ed220-50) can infinitely delay lift and fall. Delay range is from rated
action time to 30 seconds. Specific delay can be set as per customer's
requirement.
Special products
Mounting
Anti-corrosive products can be provided,stroke
can be decided by customers.Others special
requirements specify when ordering,Please.
With exceptiong of type ≤300N
the foot lugs can be installed
around 90 °
at order),head of thruster can
turn freely around 360°
rusters can be installed perp-
endicularly,angularly
and can also be installed.
