QWZ5-250/32 Pneumatic Drum Brake

⚙️ Product Overview

The QWZ5-250/32 is a Pneumatic Drum Brake designed for industrial applications requiring reliable braking powered by compressed air. It belongs to the QWZ series, which is known for its compact design, aesthetic appearance, and stable performance.

The model number typically indicates:

QWZ: The series designation for Pneumatic Drum Brakes.

5: A design variant or generation indicator.

250: The compatible Brake Drum Diameter of 250 mm.

32: Likely refers to the required air cylinder bore size or a specific connection/port dimension relevant to the pneumatic actuation.

💡 Key Features & Characteristics

Pneumatic Actuation:
Utilizes compressed air to actuate the brake shoes. This makes it ideal for environments where electrical sparks must be avoided or where pneumatic systems are already in place.

Compact & Durable Design:
The QWZ series is characterized by a small, "beautiful" footprint with a bright, corrosion-resistant finish. It is designed to be耐磨 (wear-resistant) and stable during long-term operation.

Long Service Life:
Features high-quality brake linings (shoes) that offer a long usage cycle. The design ensures smooth operation and flexible rotation of components.

Versatile Application:
Suitable for a wide range of heavy industries, including metallurgy, mining, and lifting transportation. It is particularly well-suited for port and dock operations.

Maintenance Friendly:
The structure allows for easy inspection of the brake shoes (tiles) and smooth operation checks.

🏭 Typical Applications

The QWZ5-250/32 is commonly used in:

Port & Dock Machinery: Cranes and conveyors where pneumatic power is standard.

Metallurgy: Steel mill machinery requiring robust braking.

Mining: Hoists and winches in mining operations.

Lifting Equipment: Various overhead cranes and material handling systems.

📋 General Technical Specifications

Note: As a pneumatic device, ensure the air supply pressure matches the specifications required to generate the necessary braking torque. Regular checks on the brake shoe installation and component flexibility are recommended to maintain optimal performance.
