What Is The Principle Of Pneumatic Brake

Experience has shown that wind turbines require the installation of a pneumatic brake on a stall regulator.

Some wind turbines operating under no load during storms have shown that as the speed increases, the forces acting on bladed wind turbines are large.

In some cases, the tower collapsed due to overload, and in other cases, the blades were deformed or broken.

The air brake reduces the speed in emergencies such as zero shaft torque and mechanical brake failure. It is activated when the speed is increased, and any mechanical device can be used as long as the air brake is activated.

In fact, high reliability machinery is preferred, and a centrifugal mechanism is often used.

Failure to start the air brake will have fatal results.

The disadvantage of the central air brake is that it needs some kind of device that transmits the release signal to the air brake. This link can be a weakness, and failure of this link can lead to unexpected failures. The release air brake with release device is constructed separately from the activation device nearby.

Because of the large number of release devices, there is a high probability that at least one air brake will be activated. Because the centrifugal force increases in proportion to the radius, if the centrifugal force is used as the release standard, there is an advantage at positions greater than the radius.

Pneumatic brakes are widely used in wire and cable equipment due to their simple structure, stable operation, convenient installation, no noise, good linearity, no no-load torque, fast heat dissipation, light weight, easy adjustment, and high temperature resistance at high loads. , Packaging machinery, printing machinery, textile machinery, wire and cable machinery, winding machines, machine tools and equipment in major industrial machinery drive systems. Pneumatic brake can play the functions of cutting off, combining, jogging, reversing, speed change, etc. It adopts DC24V voltage, and the voltage fluctuation cannot exceed the rated voltage of plus or minus 5%, and the friction surface must not be contaminated with any oil and various influences. Debris in normal operation of the disc brake. When installing the air-pressure disc brake, it should be positioned axially, the air gap should be adjusted to the specified value, and the coaxiality should be kept within the range of 0.1mm in order to maintain the normal working and characteristics of the pneumatic brake.
