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.
Product description
系列:
BYW、BYWZ5(B) Series

OPERATING CONDITION

Altitude

<2000m

Ambient

temperature
-20℃~+50℃

Relative

humidity

90%

AC 3 phase 380V/50Hz

Operating duty

Intermittent(S3-60%.≤1200/h)and continuous(S1)

Be suitable for such location full with explosive mixture formed by air and combustible gas , explosion-proof class and temperature class of which respectively are IIA/IIB/IIC and T1-T4 specified by “ Electric equipments used in explosive gas atmosphere-Part II Explosion-proof ‘d’ .” in GB3836.2 standard. 

MAIN FEATURE

01

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.

02

At main hinge points where are equipped with self-lubricating bearings,which make higher efficiency of transmission and longer performance life.

03

Brake spring is arranged inside square tube and surveyor's rod is placed on one side. It is easy for customers to read braking torque value and avoid the troubles of measuring and computing.

04

Brake lining is of card-mounted and entirely shaped structure, which is easy and quick to replace. Brake lining of various materials such as semi-metal (non-asbestos) hard and half-hard, soft (include asbestos) substance are available for customer to choose.

05

Our company's new types of thrusters are adopted, which work acutely and have long life.
