How to Choose an Appropriate Permanent Magnetic Air Compressor
With the development of science and technology, air compressor is widely used in various industries as important powering equipment, including machinery, metallurgy, construction, electronics, chemical industry, food industry and so on. However, as its energy-extensive consumption, the new design permanent magnet air compressor has replaced the old “energy vampires” gradually and be well liked in the market with the advantages of energy-saving and high-efficiency, which saves cost for 20% to 40% directly for the users. But the only risk of the permanent magnetic air compressor is demagnetization. So what will contributes to demagnetization?
Protection Grade
The protection grade of permanent magnet air compressor is divided into IP23 and IP54. Owing to the working temperature, IP23 can only be designed as opening mold. But the using environment is always poor with dust, moisture, salt spray and other corrosive gases, which leads to the short service life. What’s more, some dust that contains metal particles will enter into motor and effect the distribution of magnetic field, thereby lowing efficiency. But higher grade IP54 compressor can avoid these risks successfully.
Heat-resistance Grade
As the motor of permanent magnetic air compressor is made of super strong neodymium magnets, the working temperature is especially important. If the temperature excesses the heat-resistance grade, the magnetic flux density will decrease greatly. Commonly, there are three grades of high temperature neodymium magnets, respectively, N series with 80° C, H series with 120° C, and SH with more than 150° C.
Heat Radiation Capacity
Since the special materials of the permanent magnet air compressor motor, it is necessary to ensure heat dissipation and cooling. Nowadays, there are mainly three cooling methods: air cooling, water cooling and oil cooling.
Consequently, according to different working environments and compressing requirements, it is necessary to choose the most appropriate permanent magnetic air compressor with proper protection grade, correct neodymium magnets and favorable cooling method.
