1. power hydraulic of drum brake Introduction

WZseries electro-hydraulic brake is mainly used in mechanical brake, such as hoisting, transportation, metallurgy, mines, ports, construction.

2. hydraulic of drum brake advantage

1) YWZ series use the Ed pusher as its driving device.

2) Multiple installation, high operating frequency, smooth braking, adjustable braking torque ,

f   riction liner are easy to change, long service life, no noise.

3)The operating frenquency is 2000 times per hour, electrical insulation class is E, protection

 class is IP65, the products accordance with JB/T7021-1993 and JB/T6406-1992 standards.

3.Conditions of usage

1) Working temperature: -40 °C -50 °C.

2) The air relative humidity is not more than 90%

3) In no danger of explosion, conductive dust and medium without gas corrosion and damage to the insulation.(Flame-proof products should be discussed separatly)

4) Mainly used for the power with 3phase ,50HZ, 380V (we can provide the products according to the customers requirements which suit for 60HZ or different voltage, so please inform us before you order if there is a special request).

5) Installation altitude in accordance with GB755-2000 standard.

6) The YH-10 Aviation Oil should be instead of pusher’s working solution or the there is a heater attachment when the working temperature is below -20 °C
