Usually in industrial production, product processing manufacturing fan equipment is mainly used in boiler combustion system, drying system, cooling system, ventilation system and other occasions, according to the production needs of furnace pressure, wind speed, air volume. Temperature and other indexes are controlled and adjusted to meet the requirements of technology and operating conditions, while the most commonly used means of control are to adjust the size of the wind door and the opening of the baffle to adjust the controlled object. In this way, no matter the production demand, the fan must run at full speed, and the change of operating conditions makes the energy consumption by throttle and baffle throttling loss. In the production process, not only the control accuracy is limited. It also causes a large amount of energy waste and equipment wastage. As a result, the cost of production is increased, the service life of equipment is shortened, and the maintenance and maintenance cost of equipment is high.

Pump equipment in the field of production also has a wide application space, water pumping station, water tank feeding and drainage system, industrial water (oil) circulation system, heat exchange system are used centrifugal pump, axial flow pump, gear pump. In addition, throttling equipment such as adjusting valve, backflow valve, shutoff valve and so on are used to control flow, pressure, water level and so on according to different production requirements. In this way, it not only causes a large amount of energy waste and damage to the sealing performance of pipes and valves, but also accelerates the wear and cavitation of the pump cavity and valve body, seriously damages the equipment, affects the production and endangers the quality of the products.

In recent years, due to the urgent need of energy saving and the continuous improvement of product quality, it is easy to operate, maintenance-free, high control precision, and can achieve high function by using frequency conversion governor (abbreviated as frequency converter). Therefore, the scheme of frequency converter drive began to replace the control scheme of air valve, baffle and valve step by step.http://www.jnblower.com/
