In fish farming plants, the cost comparison between traditional blowers and magnetic levitation blowers is as follows:

Acquisition cost:

Traditional blowers, such as Roots blowers, are relatively affordable. Generally speaking, ordinary small roots blowers can be bought for several thousand yuan, and the price of roots blowers with slightly higher power and better performance ranges from tens of thousands of yuan.

Magnetic levitation blower: Because it adopts advanced magnetic levitation technology and high-end parts, the manufacturing process is complicated, so the purchase cost is high. Usually, the price of a magnetic levitation blower is several times or even higher than that of a traditional Roots blower, and the price of magnetic levitation blowers in the market generally ranges from tens of thousands to hundreds of thousands of yuan.

Operating costs:

Traditional blower:

Energy consumption: the efficiency of traditional blowers is relatively low, especially when running at part load, the energy waste is obvious. For example, the efficiency of Roots blower is generally between 70% and 90%, and its energy consumption level is high. If it runs for a long time, the electricity expenditure is a big cost.

Maintenance cost: traditional blowers need regular maintenance, such as replacing lubricating oil and filters, and may also need to overhaul and replace mechanical parts. These maintenance work needs to consume certain manpower and material resources, resulting in corresponding expenses. Taking Roots blower as an example, the annual maintenance cost may range from several thousand yuan to ten thousand yuan, depending on the frequency of use and maintenance requirements of the equipment.

Magnetic suspension blower:

Energy consumption: Magnetic suspension blower has a high efficiency, which can usually reach more than 90%, and can save energy by 30%-40% or even more compared with traditional blowers. For example, under the same working conditions, running a magnetic levitation blower for one year may save tens of thousands of yuan in electricity compared with Roots blower.

Maintenance cost: The magnetic suspension blower adopts the magnetic suspension bearing technology, so there is no mechanical contact and friction, so the wear is very small, and the daily maintenance is relatively simple, mainly replacing the air filter regularly, and the maintenance cost is low. Usually, the annual maintenance cost may be only a few hundred yuan to several thousand yuan, which has great advantages compared with traditional blowers.

Service life:

Traditional blower: The service life of traditional blower is generally about 5-10 years, depending on the quality of equipment, use environment and maintenance. If used and maintained improperly, its service life may be shortened.

Magnetic suspension blower: The service life of magnetic suspension blower is relatively long, which can reach 20 years or even longer. Its advanced technology and high-quality materials make the equipment more durable, and it can run stably for a long time under normal use and maintenance, reducing the frequency and cost of equipment replacement.

Generally speaking, although the purchase cost of magnetic levitation blower is high, it has obvious advantages in operating cost and service life. In the long run, it may have better economic benefits and comprehensive cost benefits in the application of fishery aquaculture plants, especially for large aquaculture plants or places with high energy consumption and environmental requirements, magnetic levitation blower is a more advantageous choice. However, for some small aquaculture plants or limited budgets, traditional blowers may be more cost-effective in the short term.
