The air compressor driven by permanent magnet variable frequency has a series of remarkable features, as follows:
air pressure stability: due to the stepless speed regulation characteristics of the frequency converter, the permanent magnet variable frequency air compressor can start slowly, and can quickly adjust and respond to the occasion of large gas fluctuations, so that the air pressure stability has been significantly improved.
Start without impact: The inverter itself contains the function of a soft starter, which makes the current of the permanent magnet variable frequency air compressor at the start-up time smaller, usually not more than 1.2 times the rated current, which greatly reduces the impact of the start-up, and is beneficial to the power grid and mechanical systems.
Variable flow control: Different from the traditional power frequency drive air compressor, which can only work in one exhaust volume, the permanent magnet variable frequency air compressor can work in a relatively wide range of exhaust volume. The frequency converter adjusts the motor speed in real time according to the actual gas consumption to control the displacement and realize high efficiency and energy saving.
The voltage adaptability of the AC power supply is good: because the inverter adopts excessive modulation technology, the permanent magnet variable frequency air compressor can still output enough torque to drive the motor when the AC power supply voltage is slightly lower, and the voltage is slightly higher. The voltage to the motor is too high.
High efficiency and energy saving: The permanent magnet motor is made of rare earth materials and has its own magnetic field, which can directly convert electrical energy into kinetic energy with high efficiency. Under the same exhaust pressure, the permanent magnet variable frequency air compressor can output more gas flow than the general air compressor, and consume less power, so it can save a lot of electricity and reduce operating costs.
Low noise: Due to the use of oil-free lubrication technology and other noise reduction measures, the noise level of the permanent magnet variable frequency air compressor is low, reducing noise pollution.
Long life: The rotor of the permanent magnet synchronous motor is made of high-strength neodymium iron boron material, which has high magnetic field strength and strong excitation field, making its service life much longer than ordinary asynchronous motors.
Small vibration and high reliability: The special structure design and manufacturing process and the selection of high-quality parts make the permanent magnet variable frequency air compressor run smoothly and reliably with minimal vibration.
In summary, the air compressor driven by permanent magnet variable frequency has the characteristics of stable air pressure, no impact at startup, variable flow control, good voltage adaptability, high efficiency and energy saving, low noise, long life, low vibration, and high reliability. These features make permanent magnet variable frequency air compressors the first choice in many industrial applications.
Medical air has many important uses in medical facilities. The following is a detailed summary of its uses: Clean and purify air: Medical air is filtered, sterilized, and purified, which can effectively reduce bacteria, viruses and other pollutants in the air. Ensure
Oil air compressor refers to an air compressor that reduces friction and heat by spraying lubricating oil into the compressor during the air compression process, thereby ensuring the normal operation of the machine. This air compressor mainly relies on lubricating oil for lubrication, cooling and sealing during compression.
Water-only machinery and equipment-oil-free air compressor can be divided into permanent magnet frequency conversion and power frequency, which refers to the starting mode of air compressor motor. So what is the difference between the two, the user and how to choose? Permanent magnet variable frequency air compressor is through the controller or inverter internal
Dry oil-free air compressor may have a variety of failures. The following are some common failures and their possible causes: High current: The host is malfunctioning. Exhaust pressure too high. The voltage is too low. Because the power of the oil-free air compressor is usually
Whether the screw air compressor will stop and how much time it will stop after the maintenance time exceeds a certain limit may vary depending on the equipment model, brand and setting. However, based on information from multiple sources, the following general
The slow pumping of air compressor may be caused by a variety of reasons. The following are some common reasons and corresponding solutions: Common reasons Pollutant blockage: Air inlet or filter system accumulates dust, grease and other pollutants: These impurities will restrict the smooth flow of gas, and then
The oil content of compressed air ≤ 0.01 mg/m & sup3; is not micro-oil, but belongs to the international standard ISO 8573-1 Class 0 (Class 0) standard, which is usually regarded as equivalent to the oil content of oil-free compressed air. The following is a detailed explanation of this conclusion: the 1. State
Micro-oil air compressor and oil-free air compressor, both of which are like two unique roles in the field of air compression, each has distinct characteristics and advantages. The micro-oil air compressor is like a budget-conscious engineer. While ensuring performance, it also pays attention to economy
In the process of food production, compressed air is an important auxiliary tool, which is widely used and critical. However, the issue of whether compressed air can come into direct contact with food is related to food safety and product quality and must be treated with caution. Shanghai Granklin Group
Under normal circumstances, whether the factory will be equipped with air compressors mainly depends on its production process and process requirements. Generally speaking, many factories do configure air compressors, because air compressors, as important equipment for providing compressed air, play a role in a variety of industrial production processes.
