YW-E系列两步式电力液压鼓式制动器 YW-E SERIES TWO-STEP EL ECTRO0-HYDRAULC DRUM BRAKES

应用APPLICATION



●YW-E系列电力液压鼓式制动器广泛应用于各种大中型室外起重机的大车运行机构,具有优越的减速制动性能和理想的防风制动效果;该产品还可用于大型特种起重机的大、小车运行机构,可实现平稳的减速制动和可靠的维持制动;该产品用于皮带运输的工作制动也具有理想的制动性能。
●YW-E系列制动器为两步式制动装置。一制动,施加一个较小的(可根据需要在规定范围内调整)制动力矩,进行较平稳的减速制动,待机构停止运动后,二制动开始,并增加一个制动时间,可根据实际需要通过阻尼油缸回路中的单向调速阀进行调整(调整范围为1-15秒)。
APPLICATION
●Two-step, Delayed electro-hydraulic drum brakes can be extensively used on large/middle outdoor cranes, having excellent decelerati-on braking and storm braking performance. It can also be used on large and middle special cranes , realizing stable deceleration braking and maintenance braking. ldeal braking performance of these series products is also represented on Belt transport vehicles.
●The YW-E series brake is two-step braking device. In the first braking step, a minor torque (adjustable with the prescribed limits)is exerted to make stable deceleration braking. When body stops, the second step starts. A bigger torque (adjustable with the prescribed limits) is exerted to realize reliable maintenance or storm braking. The interval time between the two steps staring can be adjusted by damping single way throttle in cylinder circuit (with 1-15 seconds ).

主要特点MAIN FEATURE



●制动衬垫为卡装式整体成型结构,更换十分方便、快捷。
●联锁式退距均等装置,使用中始终保持两侧瓦块退距均等,避免退距不均使一侧制动衬垫浮贴制动轮的现象。
●主要摆动铰点均没有自润滑轴承,传动效率高,寿命长,使用过程中无需润滑。
●采用Ed系列推动器配套,动作灵敏,寿命长。
●常闭式设计,(断电)弹簧制动,(通电)推动器释放。
MAIN FEATURE
●Brake lining is of clamped integral forming structure, which is easy and quick to replace.
●Interlocking shoe clearance balancing device and shoe auto- aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brake wheel.
●Main hinge points are equipped with sef-lubricating bearing, making high ficiency of transmission, long service ife.
Lubricating is unnecessary during operation.
●The Ed series thrusters are characterized by flexible action and long operating ife.
●Brake closes in case of power failure (F ail- Safe Principle). Braking by spring power. Lifing by thruster.
