  Advantages and Disadvantages of Permanent Magnet Inverter Air Compressors   We are in the energy-saving era. No matter what kind of product we choose, we will take its energy-saving effect into account as a reference value for purchase. In the past two years, a new type of permanent magnet variable frequency air compressor has been released in the field of air compressors. This type of product has entered a higher energy-saving height with the air compressor, and it is the product with the best energy-saving effect among all types.     Advantages of permanent magnet frequency conversion air compressor:   1. The air pressure of the permanent magnet frequency conversion air compressor is stable Since the variable-frequency screw air compressor utilizes the stepless speed regulation feature of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter; it can also quickly adjust and respond to occasions with relatively large fluctuations in air consumption. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.   2. There is no impact when the permanent magnet variable frequency air compressor starts Since the inverter itself has the function of a soft starter, the starting current is within 1.2 times of the rated current. Compared with the power frequency starting, which is generally more than 6 times of the rated current, the starting impact is very small. This kind of impact is not only on the power grid, but also on the entire mechanical system, which is also greatly reduced.   3. Variable flow control of permanent magnet frequency conversion air compressor The air compressor driven by power frequency can only work in one displacement, and the variable frequency air compressor can work in a wider range of displacement. The frequency converter adjusts the motor speed in real time according to the actual gas consumption to control the exhaust volume. When the air consumption is low, the air compressor can also be automatically dormant, which greatly reduces energy loss. The optimized control strategy can further improve the energy saving effect.   4. The AC power supply of the permanent magnet variable frequency screw air compressor has better voltage adaptability Due to the overmodulation technology adopted by the frequency converter, it can still output enough torque to drive the motor when the AC power voltage is slightly low; when the voltage is slightly high, it will not cause the output voltage to the motor to be too high. For self-generating occasions, variable frequency drive can show its advantages. According to the characteristics of the motor VF (variable frequency air compressors work below the rated voltage in the energy-saving state), the effect is obvious for the site with low grid voltage.   5. Permanent magnet variable frequency energy-saving air compressor with low noise Most of the working conditions of the frequency conversion system work at lower than the rated speed, the mechanical noise and wear of the main engine are reduced, and the maintenance and service life are extended. If the fan is also driven by frequency conversion, it can significantly reduce the noise of the air compressor when it is working.     After understanding the advantages of the product, we should also grasp the shortcomings of the product. The following summarizes the shortcomings of the permanent magnet variable frequency air compressor:   1. Fear of demagnetization The motor used in the permanent magnet variable frequency air compressor is a permanent magnet motor, and the weakness of this kind of motor is that it is afraid of demagnetization. The magnet steel determines the demagnetization. If the motor is in a high temperature state for a long time, it is prone to demagnetization.   2. Maintenance is relatively troublesome Compared with ordinary compressors, the maintenance of permanent magnet frequency conversion models is relatively troublesome. During the maintenance process of the machine head, the motor must be disassembled before the machine head can be disassembled, and professional tools are required (the rotor has a strong attraction), requiring professionals to carry out maintenance work.

  Compressors are the source of power, and compressed air systems have become the needs of more and more industries. So, which industries will use air compressors?   1. Electric power industry Main application: compressed air system for instrumentation, compressed air system for ash removal, compressed air system for miscellaneous use in factories, water treatment including boiler feed water treatment and industrial wastewater treatment system, and compressed air system for equipment power in hydropower stations.   2. Cotton spinning industry Main application: The cotton spinning industry mainly uses clean compressed air as the power source, which requires oil content; the chemical fiber industry mainly uses air for instrumentation and suction guns, and the printing and dyeing industry mainly uses air for power and instrumentation.   3. Food and drink Main application: gas for non-contact, indirect contact and direct contact. The air source can be provided by an oil-free compressor without contact, such as cleaning of cans and beverage bottles; direct contact: such as raw material stirring, fermentation, etc., does not require high oil content, and the air source can be provided by a micro-oil screw.   4. Pharmaceutical industry Main purpose: Non-contact is mainly used for power execution and instrumentation. Direct contact is due to the large amount of air consumption and stable air consumption. At the same time, air quality is required, and the centrifugal type is generally used; if the air volume is not very large, a vortex machine can be used for post-treatment. device, or use oil-free screw.   5. Rubber and plastic products Main application: used for power execution and instrument gas, plastics are also used in bottle blowing process.   6. Metallurgical industry Main application: the metallurgical industry is divided into iron and steel industry and non-ferrous metal smelting and production industry   Iron and steel industry: mainly for power execution, instrument gas, and instrument purging. Non-ferrous metal smelting and manufacturing: mainly used for power execution, instrument gas, spraying, etc.   7. Transportation industry Main application: Braking brakes of trains, track changing devices, opening and closing of vehicle doors and windows, automatic control of subways, automatic equipment of ships, maintenance of aircraft, inflation of automobile hovercraft, loading and unloading of docks, etc. Application of pneumatic devices very wide.   8. Aerospace industry Main application: Because pneumatic devices can not only withstand radiation and high temperature, but also withstand large acceleration speeds, they are gradually widely used in the control of modern aircraft, rockets, and missiles.   9. Chemical and military enterprises Main application: It has been widely used in the transportation of chemical raw materials, the filling of harmful liquids, the packaging of explosives, the automatic control device of torpedoes, the automation equipment of ships, and oil drilling and production.   10. Electronics, experiment and instrument industry Main application: It plays an important role in the production of some precision electronic products, in the process of experimental testing, and in the control and detection of instruments.   The above are the needs and requirements of all walks of life for air compressors!
