防爆型电力液压鼓式制动器 EXPLOSION PROTECTED EL ECTRO-HYDFAULIC DRUM BRAKES

应用APPLICATION



●防爆型型电力液压鼓式制动器,广泛应用于有隔爆要求的各种起重运输、皮带运输、港口装卸、冶金及建筑机械中各种机构的减速和停车(维持)制动。
APPLICATION
●Explosion protected electro-hydraulic drum brakes can be extensively used for deceleration and stop/braking of various mechanisms in various belt transport, port handling, hoisting, metallurgical and building machinery which have explosion protected requirements.

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。
●(YWZ5系列)联锁式退距均等装置,使用过程中始终保持两侧瓦块退距均等,避免因退距不均使一侧制动衬垫浮 贴制动轮的现象。
●主要摆动铰点均设有自润滑轴承,传动效率高,寿命长,使用中无需润滑。
●(YWZ5系列)制动弹簧设在方管内布置并设有标尺,保护弹簧不受损坏和污染。
●采用Ed系列隔爆型推动器配套,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.
●(YWZ5 Series) 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 self-lubricating bearing, making high efficiency of transmission,long service life. Lubricating is unnecessary during operation.
●(YWZ5 Series) Enclosed spring tube protects spring from damage and contamination.
●The Ed series explosion protected thrusters are characterized by flexible action and long operating life.
●Brake closes in case of power failure (Fail-Safe Principle). Braking by spring power. Lifting by thruster.

符合标准 STANDARDS COMPLIANT
