Taizhou Yaxin Marine Electric Motor Manufacturing Co., Ltd. is an integrated electric motor manufacturer that encompasses research, production, sales, and service. With rapid growth in recent years, Yaxin Electric has established a comprehensive advantage in talent, technology, market, and brand.
Marine variable-frequency explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical, and chemical industries. Additionally, they are widely applied in sectors such as textile, metallurgy, urban gas, transportation, grain and oil processing, papermaking, etc.
The explosion-proof motor has the same rated voltage, rated current, power, and speed as a standard motor. The difference is that the explosion-proof motor includes an additional explosion-proof symbol: Ex.
Marine Variable Frequency Explosion-proof Electric Motors Temperature Categories: T1~T6. Ignition temperature of combustible gases: Electrical equipment temperature T1 >450℃; T2 450℃>T>300℃; T3 300℃>T>200℃; T4 200℃>T>135℃; T5 135℃>T>100℃; T6 100℃>T>85℃. Development: With the advancement of technology and production, the number of locations with explosion hazards is also increasing. For instance, in the past, edible oil production was done through traditional pressing methods. Since the 1970s, China began to introduce foreign solvent extraction oil technology, which requires the use of hexane-containing chemical solvents, and hexane is a flammable and explosive substance. Therefore, solvent extraction workshops have become hazardous areas for explosions, necessitating the use of explosion-proof electric motors and other explosion-proof electrical products. Similarly, with the rapid development of China's highways and the emergence of batch fuel stations, new markets for explosion-proof electric motors have been created.
Key features of explosion-proof motors include:
1. The power rating, installation dimensions, and speed correspondences align with DIN 42673. Considering the inheritance with the YB series and interchangeability with the Y2 series, necessary adjustments have been made for enhanced effectiveness and applicability.
2. Full series utilizes F-grade insulation, temperature rise evaluated according to B-grade standards.
3. Noise limits are lower than the YB series, approaching the I-grade noise level of the YB series; vibration limits are comparable to the YB series.
4. The shell protection level is upgraded to IP55.
5. The entire series uses low-noise deep groove ball bearings, and motors with a base center height of 180mm or above are equipped with oil injection and drainage devices.
6. The motor radiator fins come in two types: parallel horizontal distribution and radial distribution, with the parallel horizontal distribution being the predominant type.
7. Key performance indicators reach international standards of the early 1990s.
Marine variable-frequency explosion-proof motors utilize a flameproof enclosure to isolate the electrical components that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixtures. However, this enclosure is not airtight; explosive gases can enter the motor interior through gaps at the junctions of its various parts. When these gases come into contact with ignition sources such as sparks, arcs, or high temperatures inside the enclosure, an explosion may occur. In such cases, the motor's flameproof enclosure not only remains undamaged or deformed but also prevents the flame or hot gases from igniting the surrounding explosive gas mixture as they pass through the junction gaps.
Taizhou Yuanxin Marine Electric Motor Manufacturing Co., Ltd. has passed the ISO9001:2000 international quality system certification, and the total production and sales volume of electric motors has been increasing year by year.
