ZWZA系列直流電磁鼓式制動器 ZWZA SERIES DC ELECTROMAGNETIC DRUM BRAKE

應用Application

·ZWZA系列直流電磁鼓式制動器，主要用于電磁吊及各種直流驅動或直流電網(wǎng)的起重、港口裝卸及冶金機械中各種機構的減速和停車制動。對于交流驅動的各種起重、港口裝卸及冶金機械不推薦使用。

APPLICATION

·ZWZA series DC electromagnetic drum brake is mainly used for electromagnetic liting, lifting of variousDC drive or DC power grid,deceleration and parking brakes of various mechanisms in port handlingand metallurgical machinery.AC-driven lifting,port handling and metallurgical machinery are notrecommended.

符合標準Standards Compliant

·ZWZA系列制動器的安裝尺寸和制動力矩參數(shù)符合JB/ZQ4386-2006標準。技術要求符合JB/T7685-2006標準。

STANDARDS COMPLIANT

·Installation dimensions and braking torque parameters of ZWZA series brakes are in accordance withJB/ZQ4386-2006. Technical requirements meet JB/T7685-2006 standards.

使用條件 Operating Condition

·環(huán)境溫度:-25℃~+40℃

·操作頻率小于720c/h

·使用地點的海拔高度不超過2000m

·制動器周圍工作環(huán)境中不得有易燃、易爆及足以腐蝕金屬及破壞絕緣的氣體和導電塵埃。

·在空氣相對濕度不大于90%的室內或有防雨、雪的裝置下使用。

·電源電壓:直流DC110V或DC220V，若有特殊要求，請訂貨時協(xié)商確定。

OPERATING CONDITION

·Ambient temperature: -25℃~+40℃

·Operating frequency less than 720c/h

·The altitude of the place of use shall not exceed 2000m

·The working environment around the brake must be free from inflammable, explosivegases and conductive dustsufficient to corrode metals and destroy insulation.

·Used indoors with air relative humidity not more than 90% or under rain or snowprotection devices.

·Power supply voltage:DC110v or DC220V.Please negotiate when ordering ifspecialrequirements are required by users.

主要特點 Main Feature

·制動彈簧在方管內布置并設有標尺，保護彈簧不受損壞和污染。

·主要擺動鉸點均設有自潤滑軸承，傳動效率高，壽命長，使用中無需潤滑。

·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。

·常閉式設計，（斷電）彈簧制動，(通電)電磁釋放。

MAIN FEATURE

·Enclosed spring tube protects spring from damage and contamination.

·Main hinge points are equipped with self-lubricating bearing，making high effioiency oftransmission,long ser vice life.Lubricating is unnecessary during operation.

·Interlocking shoe clearance balancing device and shoe auto-aligning device constantlyequalize the clearance of brake shoes on both sides and make adjustment unnecessary,completely avoiding brake lining one side sticking to brake wheel.

·Brake closes in case of power failure(Fail-Safe Principle). Braking by spring power.Electromagnetic release.
