In the industrial production and the product processing manufacturing industry, the fan, the pump kind equipment application scope is widespread; Its electric energy consumption is a large amount of production expenses. With the deepening of economic reform, the market competition is becoming more and more serious. Energy saving and consumption reduction has become one of the important means to reduce production cost and improve product quality.
In the industrial production and the product processing manufacturing industry, the fan, the pump kind equipment application scope is widespread; Its power consumption and throttling loss of equipment such as valves and baffles, as well as maintenance, maintenance costs account for 7-25% of the production cost, which is a large amount of production expenses. With the deepening of economic reform and the intensification of market competition, energy conservation and consumption reduction have become one of the important means to reduce production cost and improve product quality.
In 80s, the technology of variable frequency speed regulation developed at the beginning of the year, which is in compliance with the requirements of the development of industrial production automation. Opened a new era of intelligent motor. A change in the ordinary motor can only run at a fixed speed of the old mode. The motor and its drag load can be adjusted according to the requirements of the production process without any modification, thus reducing the power consumption of the motor to achieve the purpose of efficient operation of the system.
In 80s, the technology was introduced and popularized in China. It has been applied in electric power, metallurgy, petroleum, chemical, papermaking, food, textile and other industries. At present, the frequency conversion speed regulation technology has become a main development direction of modern power transmission technology. Excellent speed regulation performance, remarkable power saving effect, improve the operating conditions of existing equipment. The advantages of improving the safety reliability and equipment utilization ratio of the system and prolonging the service life of the equipment are fully reflected with the continuous expansion of the application field.http://www.jnblower.com
