Special requirements can be discussed in order.
2.Application：
ED series electric hydraulic driving device is a motor, centrifugal pump, oil cylinder as a whole, compact drive control device, has been widely used in various drum brake and disc brake driving device, also can be used for various industrial valves, gate, directional swing and rotation ( < 90degrees ) device ( mechanism ) and clamping device driving device.
3.Main Feature：
l The casing is made by casting aluminum alloy ,light and good-look.
l Electrical motor is of non-under-oil structure,B grade or F grade insulation (according to customer's requirements)durable and good heat resistance.
l Cover of junction box is tightly sealed.Cable stuffing box is adopted for inner wire,which is firm and reliable.Electrical protection of casing reaches IP55 grade.
l The surface of motor axle and pusher is handled specially to mark the sealing parts much more durable.
l Balancing air house is set at one side of oil cylinder casing which can make the thruster to be installed at any direction within rang of 0-180 degree and enlarge the using range.
l All sealing parts and bearing of Ed series are all world famous products.The sealing is reliable and durable.
l Fastening parts of Ed series are made of stainless steel,good-look and durable.
4. Additional Option
l Up limit switch,which can indicate whether brake is open,or whether the thruster is at the right position.
l 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.
l Build-in spring or release spring only for short thruster)Spring force can be decided by customers,but within the force limit of built-in spring (refer to parameter tables).
l Heater Customers can require heaters in the place where ambient temperature is below -25°c,Parameters of heater are attached (refer to Tab.1)
l Up delay valve,down delay valve,Up/down delay valve,can prolong the lifting and falling time without limit,delay range from rated action time to 30 second,specific delay valve can be set as customers' requirements.
