YWZ4厂用防爆型电力液压鼓式制动器  YWZ4 EXPLOSION PROTECTED ELECTRO-HYDRAULIC DRUM BRAKES

应用 Application

·防爆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制动。

APPLICATION

·Explosion protected electro-hydraulic drum brakes can be extensively used for deceleration and stopbraking of various mechanisms in various belt transport，port handling，hoisting，metallurgical andbuilding machinery which have explosion protected requirements.

符合标准 Standards Compliant

·YWZ4防爆型电力液压制动器安装尺寸和制动力矩参数符合JB/ZQ4388-2006标准。技术要求符合JB/T6406-2006标准。

STANDARDS COMPLIANT

·The dimensions and braking torque parameters of YWZ4series brakes comply with JB/ZQ4388-2006standard, technology requirements comply with JB/T6406-2006 standard.

主要特点Main Feature

·性能安全可靠，制动平稳,动作频率高。

·主要摆动铰点均设有自润滑轴承，传动效率高，寿命长，使用过程中无需润滑。

·联锁式退距均等装置，在使用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。

·无石棉制动衬垫与制动瓦块采用卡装插入式。安全可靠，更换方便、快捷。

MAIN FEATURE

·Safe and reliable performance, smooth braking, high action frequency.

·Main hinge points are equipped with self-lubricating bearing，making high efficiency of transmission,long service life. Lubricating is unnecessary during operation.

·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 avoidingbrake lining one side sticking to brake wheel.

·The non asbestos brake pad and the brake pad adopt the clamping plug-in type.lt is safe and reliable,convenient and quick to replace.
