How to choose a suitable magnetic levitation blower for sewage treatment plant?

Selection of a suitable magnetic levitation blower for sewage treatment plant can be considered from the following aspects:

performance parameter

Flow rate and pressure: The required air flow rate and pressure should be accurately calculated according to the scale of sewage treatment plant, the size of aeration tank, sewage volume and water quality requirements. Generally speaking, large sewage treatment plants need large flow and high pressure, while small sewage treatment plants have relatively small demand.

Efficiency: You can check the energy efficiency curve of the magnetic levitation blower by selecting the model with higher efficiency under actual operating conditions. High-efficiency blowers can save a lot of energy costs in long-term operation. Generally, magnetic levitation blowers can save more than 30% energy compared with traditional roots blowers, and about 12% energy compared with traditional gear single-stage centrifugal blowers.

Speed regulating range: The speed regulating range of magnetic levitation blower is wide, and the rotating speed can be accurately adjusted according to the actual demand, so as to realize flexible control of air volume and air pressure, which can better adapt to the changing demand of ventilation volume in different stages of sewage treatment.

Reliability and stability

Equipment reliability: The magnetic levitation blower adopts advanced magnetic levitation bearing technology, which has no mechanical contact and wear, thus reducing the risk of failure caused by the damage of mechanical parts. Its control system is also relatively precise, which can monitor the running state of the equipment in real time and protect itself.

Operation stability: The vibration of magnetic suspension blower is small when it is running, because the magnetic suspension bearing avoids the vibration caused by mechanical contact, which is beneficial to the long-term stable operation of the equipment, especially in the environment sensitive to vibration.

Installation and space requirements

Installation difficulty: The installation of magnetic suspension blower is relatively complicated, which involves the debugging of high-precision magnetic suspension bearing and control system, and usually requires professional technicians to install it, and has high requirements for installation environment, such as cleanliness, temperature and humidity.

Space occupation: under the condition of the same air volume and wind pressure output, the magnetic levitation blower occupies a relatively small area and has a compact structure. For sewage treatment plants with limited land resources, choosing equipment with small space occupation can save valuable land costs.

Noise level

The noise level of magnetic suspension blower is usually low, generally less than 80dB, and there is no noise caused by mechanical contact and friction, and some noise reduction measures, such as sound insulation cover, are also adopted in the design. If the sewage treatment plant is located in a residential area, near a hospital or a school, where noise is strictly limited, a low-noise magnetic levitation blower is a better choice.

Technical support and after-sales service

Technical support: Magnetic levitation blower is a kind of high-tech equipment, which needs professional technical support from suppliers, including equipment operation training, fault diagnosis and technical consultation. The technical team of the supplier should be able to answer the technical problems encountered by users in the process of using the equipment in time and provide services such as equipment upgrade.

After-sales service: Good after-sales service is very important to ensure the normal operation of equipment, including equipment repair, maintenance and spare parts supply. Due to the special parts of magnetic suspension blower, the timeliness and price of its spare parts supply need to be considered.

Price and cost

Purchase cost: on the premise of meeting the performance and quality requirements, compare the prices of different brands and models of magnetic levitation blowers, but don't just take the price as the only selection criterion, but consider other factors comprehensively.

Operating cost: In addition to the purchase cost, the operating cost of the fan should also be considered, including energy consumption and maintenance cost. Although the purchase price of fans with good energy-saving effect may be higher, long-term operation can save a lot of energy costs.
