YWZ4廠用防爆型電力液壓鼓式制動器  YWZ4 EXPLOSION PROTECTED ELECTRO-HYDRAULIC DRUM BRAKES

應用 Application

·防爆型電力液壓鼓式制動器，廣泛應用于有隔爆要求的各種起重運輸、皮帶運輸、港口裝卸、冶金及建筑機械中各種機構的減速和停車制動。

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.

符合標準 Standards Compliant

·YWZ4防爆型電力液壓制動器安裝尺寸和制動力矩參數(shù)符合JB/ZQ4388-2006標準。技術要求符合JB/T6406-2006標準。

STANDARDS COMPLIANT

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

主要特點Main Feature

·性能安全可靠，制動平穩(wěn),動作頻率高。

·主要擺動鉸點均設有自潤滑軸承，傳動效率高，壽命長，使用過程中無需潤滑。

·聯(lián)鎖式退距均等裝置，在使用中始終保持兩側瓦塊退距均等，避免因退距不均使一側制動襯墊浮貼制動輪的現(xiàn)象。

·無石棉制動襯墊與制動瓦塊采用卡裝插入式。安全可靠，更換方便、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.
