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

應(yīng)用 Application

·防爆型電力液壓鼓式制動(dòng)器，廣泛應(yīng)用于有隔爆要求的各種起重運(yùn)輸、皮帶運(yùn)輸、港口裝卸、冶金及建筑機(jī)械中各種機(jī)構(gòu)的減速和停車制動(dòng)。

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(biāo)準(zhǔn) Standards Compliant

·YWZ4防爆型電力液壓制動(dòng)器安裝尺寸和制動(dòng)力矩參數(shù)符合JB/ZQ4388-2006標(biāo)準(zhǔn)。技術(shù)要求符合JB/T6406-2006標(biāo)準(zhǔn)。

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(diǎn)Main Feature

·性能安全可靠，制動(dòng)平穩(wěn),動(dòng)作頻率高。

·主要擺動(dòng)鉸點(diǎn)均設(shè)有自潤(rùn)滑軸承，傳動(dòng)效率高，壽命長(zhǎng)，使用過(guò)程中無(wú)需潤(rùn)滑。

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

·無(wú)石棉制動(dòng)襯墊與制動(dòng)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.
