What are the advantages of self cooled magnetic particle brakes?

Advantages of self-cooled magnetic particle brakes:

1. The self-cooled magnetic particle brake cancels the circulating water circuit to avoid the sintering of magnetic particles caused by cooling water leakage.

2. The self-cooled magnetic particle brake does not need to be forced to cool the purified water source and water pump, which saves the space of printing machinery and reduces production consumption.

3. The self-cooled magnetic particle brake adopts an aluminum alloy shell with excellent heat dissipation.

As the tension control system for unwinding in the winding system, the self-cooled magnetic particle brake can output a large braking torque and slip power when working, and the self-cooled magnetic powder brake is widely used in web offset printing machinery. The self-cooled magnetic particle brake can continuously adjust the tension of the paper in a large range to ensure the stability and continuity of the paper during operation.

1. The self-cooling magnetic powder brake adopts an aluminum alloy shell with excellent heat dissipation, which has good heat dissipation performance and long service life of magnetic powder.

2. Eliminate the purified water source and water pump for forced cooling, save the space of printing machinery and reduce production consumption.

3. The circulating water channel is canceled to avoid magnetic powder sintering caused by cooling water leakage.

4. The braking torque is relatively large, the control power is smaller, the structure is simple, and the installation is more convenient.

The above is from Sky Transmission.

Electromagnetic powder brake, also known as magnetic powder brake, is based on the electromagnetic principle and the use of magnetic powder to transmit torque. It has the characteristics that the excitation current and the transmission torque are basically linear. It can transmit a certain torque under the condition that it has nothing to do with the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving.

Magnetic powder brake is a multi-purpose, high-performance automatic control element. It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet press and other related winding processing industries in unwinding and winding tension control. Magnetic particle brakes are also often used for dynamometer loading and braking of transmission machinery.

Characteristics of sky-machine-transmission-dynamic magnetic powder brake.

1. It can achieve continuous sliding operation.

2. Stable torque can be obtained.

3. No squeeze sound. The sluggish slippage of the operating surface occurs due to friction, but it does not occur here, and there is no connecting sound, so the operation is quite quiet.

4. The heat capacity is very large. The use of magnetic particles with excellent heat resistance and the use of an ideal cooling method make it safe to use even in the case of severe continuous sliding operation.

5. It can achieve a smooth continuous and driving state. Since the coefficient of static friction and the coefficient of dynamic friction are almost the same, there is no ** when fully connected, and the acceleration and deceleration of the load can be adapted.

The magnetic powder brake of Tianji transmission is formed by the combination of the transmission unit (input shaft) and the driven unit (output shaft). In the space between the two sets of cells, filled with granular magnetic particles (about 40 μm of reproduction). When the magnetic coil is not conductive, the torque will not be transmitted from the transmission shaft to the driven shaft, but if the coil is electromagnetically energized, it will attract the magnetic particle due to the action of the magnetic force and produce a hardening phenomenon, and the torque will be transmitted between successive sliding.

When choosing to buy magnetic particle brakes, choose products with the highest quality. Magnetic particle brakes have the following advantages:

1. CNC precision manufacturing, high precision, fine processing, good linearity and superior performance.

2. Stable operation, no vibration, no impact and no noise in the starting, running and braking states.

3. Aluminum alloy structure, with excellent heat dissipation performance, good demagnetization, and fast response speed.

Fourth, the magnetic powder has high purity, does not add black toner, stable performance and long life.

Before selecting the model, determine the application intention, such as load, continuous sliding, rewinding, tension control, starting, aborting, etc. There are also functional requirements, such as heat dissipation work, torque, response speed, control accuracy, control scale, etc. Then select the appropriate magnetic particle brake type standard according to the requirements.

When installing, it is recommended that customers pay attention to distinguishing the input shaft and output shaft of the magnetic particle brake, and the machine logo is generally marked with the logo of the input shaft and output shaft.

The differences between electromagnetic brakes and magnetic particle brakes are as follows:

Electromagnetic brake is a kind of connector that transmits the torque force of the active side to the passive side, which can be freely combined, cut off and braked as needed, and is mainly composed of wire base, iron plate and aluminum alloy guide seat. Then the magnetic particle brake is based on the electromagnetic principle and the use of magnetic powder to transmit torque. It is mainly composed of round shell, brake shaft, front and rear aluminum cover, bearing, all-copper wire, heat sink, magnetic powder, etc.

Magnetic particle brakes are relatively much more complex than electromagnetic brakes, but both are extremely widely used. Electromagnetic brakes are mostly used in electronic capacitor equipment, ultrasonic machinery, bag-making machinery, packaging machinery and other mechanical fields, and magnetic particle brakes are mostly used in textile machinery, laminating machines, slitting machines, coating machines, rubber machinery and other mechanical fields.

Water-cooled magnetic powder brake belongs to one of the magnetic powder brakes, is an important automatic actuator in modern industrial production, its working principle is that when the internal coil is energized, the magnetic particle will produce flux under the action of magnetic field lines, so that the output shaft and the input shaft become a rigid body and rotate, and produce slip when overloaded.

The water-cooled magnetic particle brake can output a large braking torque and slip power when working, and the water-cooled magnetic particle brake needs to be water-filled when it operates, and is generally equipped with a set of automatic water circulation system. Single shaft, stop support, water-cooled magnetic powder brake rated torque: Rated voltage:

DC24V magnetic particle brake is suitable for unwinding tension control Magnetic particle brake is also often used for dynamometer, loading and braking of transmission machinery. The water-cooled magnetic particle brake is more expensive than the self-cooled one, and there are two cooling methods for customers to choose from in the rotary offset press. The specific cooling methods are as follows:

There are two major cooling methods of water-cooled magnetic powder brake in the rotary offset press: 1. Real-time water supply cooling of water pump: This kind of cooling method can be selected for the water pump motor (if the water pump motor is damaged, the magnetic particle brake will fail without water cooling).

Hello, the water-cooled magnetic powder brake of Tianji transmission belongs to one of the magnetic powder brakes, which is an important automatic actuator in modern industrial production, and its working principle is that when the internal coil is energized, the magnetic particle will produce magnetic flux under the action of magnetic field lines, so that the output shaft and the input shaft become a rigid body and rotate, and produce slip when overloaded.
