Description
The CQPD - 35B is a member of the CQPD series pneumatic disc brakes, mainly designed for low - medium torque drive mechanisms. It has the characteristics of a compact structure and flexible installation, and is widely used in tension control and braking scenarios of industrial winding equipment. The following is a detailed introduction to its core information such as technical parameters, structural features, and application fieldsZhongyuan Brake:
Core Technical Parameters
| Parameter | Details |
|---|---|
| Ambient temperature | -20°C ~ +60°C |
| Maximum operating air pressure | 7 bar (0.7 MPa) |
| Air source requirement | Dry and filtered compressed air, no corrosive gas contained |
| Brake pad type | Non - asbestos brake pad (environmentally friendly and wear - resistant) |
| Installation method | It can be installed horizontally or vertically. For horizontal shafts, it can be installed at any angle around the disc (preferably horizontal installation); for vertical shafts, there is no angle restriction. One or more brakes can be configured for a single disc, and symmetrical installation is required when multiple brakes are used |
Key Structural and Performance Advantages
Unique braking and release mode: Different from the QPD series which brakes by spring and releases by pneumatic pressure, the CQPD - 35B adopts the mode of pneumatic braking and spring release. This design is suitable for scenarios that need to maintain the release state for a long time and perform braking quickly when needed.
Easy maintenance: The brake pad adopts a spring - loaded clamping installation method. When the pad is worn to a certain extent, it can be replaced quickly without complicated disassembly of the brake body, which greatly shortens the maintenance time.
Low supporting cost: It does not need to be equipped with an independent power source. It can be directly connected to the on - site air station for use, which reduces the configuration cost of supporting equipment and simplifies the overall system layout.
Compact and lightweight: Its simple structural design makes it small in size and light in weight, which is convenient for installation in equipment with limited space.
Typical Application FieldsThis series of brakes is mainly used for deceleration, stopping and braking of low - medium torque drive mechanisms, and is especially suitable as a tension brake for winding machinery. Specific application scenarios include:
Paper industry: It is used for web tension control in the papermaking process and tension control in newspaper printing, ensuring that the paper does not deviate or break due to unstable tension during transmission and printing.
Metal processing industry: It is applied to the unwinding tension control of steel coils, realizing stable feeding of steel plates or steel strips in the stamping, cutting and other processes.
Wire and cable industry: It is used for the unwinding tension control of wire and cable reels, ensuring that the wire and cable are not pulled and deformed due to excessive tension during the processing and laying process.
Other winding equipment: It can also be matched with various small and medium - sized winding and unwinding mechanisms that need stable tension control, such as the tension braking of plastic film reels and textile yarn reels.
