Explosion-proof motor is a kind of motor which can be used in flammable and explosive places. Now, explosion-proof motors are gradually favored in the petrochemical industry. What is the necessity of explosion-proof motors?

　　1. The demand of the ampered-type and sparkless motors will be on the rise. Users of petrochemical systems in use; The necessity of developing the safety and sparkless motors in our country has been recognized.

　　2. The reliability of explosion-proof motor has been paid more and more attention by users of petrochemical system. Petrochemical enterprises are developing large equipment and continuous operation, which requires the system to run for long period, free of maintenance or less maintenance. Therefore, the explosion-proof motor becomes the key equipment to guarantee the above requirements.

　　3. Explosion-proof and efficient frequency conversion and speed control motors have become energy-saving products urgently required by petrochemical users. There are two aspects of energy saving for explosion-proof motors: one is to develop high-efficiency explosion-proof motor products; the other is to develop a large number of special products for explosion-proof speed motor. In particular, the motors equipped with fans, pumps and compressors with huge energy saving potential are designed as speed motor.

　　4. New requirements brought by the development of coastal petrochemical enterprises. China's coastal areas will build a number of refineries, crude oil needs to be imported, and imported crude oil is high sulfur content, serious corrosion, so explosion protection motor is required to improve anti-corrosion performance. In addition, imported crude oil needs to be transported by sea, and its storage tanks need to be equipped with explosion-proof motors for high-lift and large-flow oil pumps.

　　5. The great development of petroleum industry in western China requires the development of explosion-proof motor products suitable for dry and hot desert environment. The market demand of the medium and large capacity ampere-type brushless excitation synchronous motor for hydrogenation device will increase year by year.
