The word-of-mouth comments with regard to the design, function, and quality of our products are spreading. Thanks to that, our brand fame has been greatly widespread.
Striving for becoming the top enterprise supplying the first-rate service is always valued at SUNRISE. All services are arranged to fulfill custom demand for pneumatic disk brake. For example, specification and design can be customizated.
Attention for Using Magnetic Particle Brake :
1, Install it with correct mounting method (make high-speed rotation side as the input side) to use the magnetic powder clutch. If the mechanical structure of output and input shafts have to be installation reversely, make sure to use the under 1000R/MIN. If the output shaft and input shaft be installed reversely, which will make the machine idle for a long time, the magnetic powder clutch will greatly shorten the life by mixing magnetic powder.
2, Note the moisture. If the magnetic is damp, then performance will become unstable, so be careful do not to let the oil or water get into the housing. Especially when installed in the gear box, oil penetrated the internal branch of the housing through the shaft, so please seal it with film completely.
3, Note the surface temperature. Caused by continuous operation, the maximum temperature of the surface is below 90 degree when running more, than the value and durability will be greatly reduced. Make sure to limit the temperature will not above90 degree, make sure to keep the use of sliding within allowed work range.
The magnetizing current has a liner relartionship with torque
As is shown in Chart 3, the transmission torque has a linear relationship with the magnetizing current. The size of the torque can get controlled within larger range. Under normal circumstance, the magnetizing current has a liner relationship with transitive torque within range of 5%~100% rated torque.
Stable slip torque
The slip totational speed between driven rotor and active rotor do not affect the transitive torque when the magnetizing current retain unchanged, as shown in Chart 4, which means, the static friction torque and the dynamic friction torque have no difference. Therefore, the torque can retain constant stably. The features are applied to tension control, users can control the tension of the roll material effectively as long as adjust the magnetizing current accurately.
Prevention heat phenomenon from slip
The friction part will generate hear inevitably or even destryed when it keep continuous sliding. But this device has a complete cooling set, it will generate a lot of heat after long time running and it has a long service life.
Powder Clutch and Brake Application
Due to the feature of the magnetic powder clutch and brake, they have been widely used in paper making, printing, plastic items, rubber industry, textile industry, printing and dyeing, wire and cable, metallurgy industry and tension control of winding and unwinding in roll material processing industry. A complete set of schematic of tension control system is as follows.
Note:
The magnetic powder clutch can be also used in buffering start, overload protection, speed adjustment; the magnetic brake can also be used in test loading and braking of transmission machinery.
Design reference
First, let us learn the meaning of the following words:
1. Slip rotational speed: the speed difference between input shaft and output shaft is magnetic powder clutch, the rotational speed of output shaft for magnetic powder brake.
2. Slip powder: the powder generated from the slip rotational speed when the magnetic powder clutch or brake transfer torque.
The selection of the magnetic powder clutch or brake rely on the maximum required torque and rotational speed. Because the temperature of all parts will rise when the slip power is converted into heat, it is guaranteed that the actual slip power is less than the rated value.
