What should I pay attention to when the belt conveyor is setting the brake?
At the end of long distance conveyor safety brake set, because the load of belt conveyor is in the entire transportation line began distribution, and the tension of heat resistant rubber belt, generally can not carry out safety braking, so we can reduce the speed of conveyor system from the mechanical system of downtime, avoid dynamic load a large and accurate pattern shape material on the conveyor belt does not slip in the case of herringbone.
Safety shutdown of transport and transport equipment downtime or velocity is close to zero the braking action, will effectively avoid the transportation industry with the decline, due to the use of backstop in transport machine, so we must set the brake on the transport belt conveyor can be quickly set up efficient backstop or brake;
In the downward inclined belt conveyor using centrifugal switch and speed protection device, in more than a predetermined speed, can disconnect the electrical control circuit, so that the brake action in the driving mechanical failure occurs it will play a protective role, downtime control in the lower conveyor, must use the brake to make load the heat resistant conveyor belt machine will not happen too much or lose control of the slide in the horizontal and inclined belt conveyor to rubber sometimes need to add a brake, overall excessive sliding will make the volume of material removed the tape machine far more than behind the reproduced or other handling equipment transport capacity therefore, should be to reduce the shutdown time of brake set;
Feedback the next level of inclined belt conveyor control speed, when the speed and load force of rubber belt motor is higher than the synchronous speed, the generator drive motor will effect the speed limit in normal running speed, when the motor is accelerated to a certain speed, and the speed of the output current is too large, the overload protection device to cut off the circuit, the motor will lose control of the annular rubber belt and its load, although the correct selection of motor and control device can avoid the accidental fault, but we need to use the brake, in order to power and emergency stop plays a role of emergency braking;
The transportation is the core mechanical braking torque during the braking process, not only with the main parameters of belt conveyer system, and dynamic load time of braking system, brake temperature rise, the factors related to braking nylon and rubber belt does not slip conditions, the braking torque in the braking process is a process, generally speaking. In the process of braking, the braking torque is not fixed;
