Choose a permanent magnet coupler, these "pits" must be avoided!

After entering the summer, this is also the peak period of the cement plant maintenance equipment. A number of cement enterprises commissioned cement internal reference to purchase a variety of permanent magnet coupler spare parts and other materials, the replacement of permanent magnet coupler demand increased significantly. As we all know, in order to protect the normal operation of cement equipment, couplers are often installed in the equipment transmission system to achieve flexible starting and reduce the impact of starting equipment. However, in actual operation, the traditional permanent magnet coupler is prone to oil leakage and other problems have brought a lot of distress to the cement plant.

In the process of long-term inspection of cement plants, the unique style of the self-developed synchronous permanent magnet coupler has been loved by many cement companies. Many cement companies are undergoing technological innovation. If the kiln conditions of cement companies are different, how to choose a permanent magnet coupler?

Different cement enterprises have similar production processes and similar production equipment. The selection of couplers first follows the principle of reliability, and gives priority to the use of permanent magnet couplers on power equipment with high reliability requirements and long continuous working hours.

The second is the principle of energy saving. No heat does not consume energy is one of the priority factors, energy saving is a direct benefit, the second calculation. The carbon emissions to be implemented are also in the interest.

The principle of quality brand, the use of products generally accepted by the market, the use of low-carbon catalog products of the Ministry of Environment of the National Development and Reform Commission, the use of products with independent intellectual property rights, the national patent award for the core patent of our company's synchronous permanent magnet coupler, and the invention patents of the United States, Japan and Australia have all been approved.

What misunderstandings do you think are currently existing in the selection of permanent magnet couplers by cement companies?

In recent years, in the early communication process with major cement companies, it is found that the major cement companies have the following misunderstandings in choosing permanent magnet couplers.

Many people confuse the fundamental difference between the eddy current permanent magnet coupler and the synchronous permanent magnet coupler. Everyone thinks that it is a permanent magnet, which is a interlayer transmission, but the eddy current permanent magnet has no elasticity, and the synchronous permanent magnet has a huge elastic displacement (elastic deformation), which can greatly reduce the maintenance of the reducer.

2. Many people think that the energy-saving effect of synchronous permanent magnet is 3% ~ 5% higher than that of eddy current permanent magnet, but the annual electricity charge is about 20% ~ 30%, that is, synchronous permanent magnet is 20% ~ 30% higher than eddy current permanent magnet, and the annual energy-saving cost can recover the difference.

Many people ignore the harm of the axial force of the vortex permanent magnet to the reducer and the motor bearing. This kind of damage takes a long time and can easily be attributed to the quality of the motor and the reducer itself.

4. Many people seal dust-proof, after long-term use, maintenance that is not frequently wiped, and after the dust is solidified, it is easy to cause the separation mechanism of eddy current permanent magnet slip protection to fail.
