      ZWZ2 Brake

      TIME:2017-08-21    AUTHOR:admin

      Name: ZWZ2 series dc electromagnetic block brake
      Description: ZWZ2 series dc electromagnetic block brakes, which must be applied to stop or decelerate mechanical parts, are called braking torque. Braking torque is the basis of design and selection of brake, and its size is determined by mechanical type and work requirement.
      Label: YWZ9 series power hydraulic block brake. DCPZ12 7 series electromagnetic clamp disc brake
      Product details:
      Brake staff can be divided into two categories, industrial brake and automobile brake are divided into driving brake (foot brake) and parking brake (handbrake). In the process of driving, the driving brake (foot brake) is generally used to facilitate the deceleration of the car during the process of moving forward, not just to keep the car still. The parking brake only applies if the driving brake fails. When the car is stationary, use the parking brake (hand brake) to prevent the vehicle from slipping and trailing. After stopping the parking brake, the parking brake is usually used to stop the parking brake, and the upper slope should be mounted on the first gear (preventing the back slip), and the downhill will be hung in reverse gear (preventing the front slide).
      ZWZ2 series dc electromagnetic block brake is called the braking torque when the mechanical working part stops or decelerates. Braking torque is the basis of design and selection of brake, and its size is determined by mechanical type and work requirement. The performance of the friction material (brake) on the brake directly affects the braking process, while the main factor affecting its performance is the working temperature and temperature rise speed. Friction material should have high and stable friction coefficient and good wear resistance. Friction material is divided into metal and non - metal. The former is commonly used in iron, steel, bronze and powder metallurgy friction materials, the latter has leather, rubber, wood and asbestos and so on.
