Ingersoll Rand Variable Frequency Air Compressor With the development of science and technology, air compressor is widely used in machinery, metallurgy, building materials, electronic power, chemical, food, textile and many other industrial fields. However, air compressors are high-energy-consuming equipment. In some industries, electricity consumption accounts for more than 30% of production power consumption, so it is commonly known as “electric tiger”.
Ingersoll-Rand Inverter Air Compressor In recent years, the permanent magnet frequency conversion series air compressor has become a hot spot and bright spot in the industry because of its energy-saving and high-efficiency characteristics. The original “electric tiger” in the market is a large-capacity air compressor, which is gradually Replaced or replaced by permanent magnet frequency conversion air compressor, directly bringing 20%-40% cost savings to users. However, in the process of using permanent magnet variable frequency air compressor, the biggest risk is degaussing caused by high temperature. Everyone knows that the permanent magnet motor is magnetic steel, and the most afraid of magnetic steel is high temperature, permanent magnet frequency conversion air pressure. The machine will gradually demagnetize under the high temperature for a long time. The higher the temperature, the greater the risk of demagnetization. The permanent magnet air compressor used in various industries has many cases of permanent magnet air compressor failure due to demagnetization of magnetic steel. Once the demagnetization speed of the press is amazing, the current of the motor will continue to increase after partial demagnetization, and the energy consumption will increase, which will increase the cost of electricity for the user. At the same time, there is a possibility that the motor will "strike" at any time, which may seriously produce the finished product line. scrapped.
What are the factors that cause the risk of degaussing?
Permanent magnet motor with high temperature resistance: The magnetic material of permanent magnet motor is made of neodymium iron boron magnetic material. As the latest result of the development of rare earth permanent magnet material, it is called “magnetic king” because of its excellent magnetic properties. The main components are: rare earth metal lanthanum. 29%-32.5% Metal element iron 63.95-68.65% Non-metallic element boron 1.1-1.2% and other elements. Another important indicator of permanent magnet motor performance is the high temperature rating, which exceeds its temperature rating and its magnetic flux density drops dramatically. The high temperature resistance grade can be divided into: N series, resistant to 80 degrees or more; H series, resistant to 120 degrees; SH series, resistant to 150 degrees or more. Motor protection level: The protection level is divided into IP23 and IP54. Due to the temperature relationship, IP23 can only be designed as an open motor. Many air compressors are used poorly, and corrosive gases such as dust, moisture and salt spray lead to low service life. In particular, the entry of metal-containing dust into the motor will seriously affect the distribution of the magnetic wires, resulting in a decrease in efficiency. The high-protection IP54 motor avoids these risks.
1, the permanent magnetic variable frequency air compressor working environment should be kept clean and dry, no dust and solid particles.
2. The permanent magnet frequency conversion air compressor gas storage tank should be placed in a good place, and welding or heating work should not be carried out within a radius of 15m.
3. Pressure gauges and safety valves should be calibrated at least once a year.
