Customized Structure-integrated Magnetic bearing-levitation centrifugal blower

Description

The magnetic suspension centrifugal blower is one kind of high-speed centrifugal blower, which doesn’t use the traditional gear transmission and mechanical bearing any more. The working principle of this kind of blower is to suspend the rotating shaft through the action of magnetism, with small friction resistance and high efficiency. which is convenient to use, low cost, little daily maintenance and gradually expanded market share.

To change the air volume by adjusting the rotation speed of the impeller which is controlled by a variable frequency inverter. The machine is of easy operation, low cost,little maintenance and has been more and more popular in water treatment, cement manufacturing and other related industries.

Application effect comparison with roots blower

Currently, the maglev blower has been widely used in China, with its high efficiency, energy saving, convenient maintenance and other characteristics of the user's praise. It has gradually become the mainstream equipment of sewage treatment plant.

Taking a municipal sewage plant as an example, the designed daily treatment capacity of the sewage plant is 50000 tons. The biological fluidized bed process is adopted. Four roots blowers are used in the aeration blower of the original biochemical tank, with a single air volume of 58.6m3/min, a pressure of 68.6kpa, a rated power of 132kw and an operating power of 117.3kw. The equipment has been used for many years, with rapid efficiency reduction, high energy consumption, high noise and high maintenance cost. Now, one yg100 maglev blower is used to replace the original four roots blowers, with remarkable results.

1. The operation power of Maglev blower is 81.2kw, which saves 36.1kwh/h and 306000 kwh / year compared with the previous equipment. It not only realizes the purpose of energy saving and emission reduction, but also saves a lot of operating costs for the sewage treatment plant.
2. Before the reconstruction, the noise of the original roots blower was nearly 120dB, which was too loud, not only made it impossible for the operators to communicate normally, but also damaged the hearing of the human body in such a working environment for a long time. However, after the reconstruction, the noise at the position one meter away from the blower was as low as 85dB, so the noise could be controlled within the acceptable range of the human body, and the normal communication could also be carried out in the blower room Flow provides a good working environment for staff.
3. Before the transformation, the original roots blower needs to replace the lubricating oil and bearing regularly, and the leakage of lubricating oil may occur. However, the modified maglev blower does not need to change the bearing and lubricating oil on a regular basis, and only needs to change the filter cotton on a regular basis, which greatly reduces the maintenance cost, thus improving the economic benefits of sewage treatment in the enterprise.
4. The maglev blower adopts an integrated skid mounted structure, which can be installed and used only on a horizontal foundation. The whole installation process is only a few hours, simple and easy to operate
5. The maglev blower has the function of remote monitoring and fault early warning, which can monitor the operation of the equipment in real time. When there is a problem in the operation of the equipment, the operation and management personnel can find the problem in time, avoid the equipment fault in the first time, and do not need to be on duty, which not only reduces the personnel input of the sewage treatment plant, reduces the cost of manual use, but also reduces the possibility of human operation error, It ensures the safety of equipment and personnel.

It can be seen from the above that the maglev blower has remarkable energy saving and emission reduction capacity in the actual application process, and has the characteristics of convenient maintenance, no need to be on duty, simple operation and low noise pollution. Under the trend of modernization of sewage treatment plant, maglev blower has become the first choice of aeration equipment in sewage treatment plant; at the same time, under the condition of marketization of sewage treatment industry, it not only greatly reduces the operation cost of sewage treatment plant, but also improves the comprehensive competitiveness of water plant, so as to promote the effective development of sewage treatment industry.
