Inverter technology saving effect is remarkable broad market space
2013/11/17 view:
Inverter technology is the variable speed AC motor needs to be born , aims to change the way to achieve AC AC frequency control . With the computer technology and power electronics technology, the application of low voltage inverter has also been rapid development. The inverter is used to improve the control precision machinery , production efficiency and product quality, while reducing energy consumption.
Use energy-saving effect is remarkable inverter technology
Since the research so far , frequency conversion technology in many production processes have achieved significant energy savings. National "energy conservation " second five "plan" required to implement energy-saving projects , motor system energy is one of the main projects , requiring the implementation of variable speed motor system , permanent control, reactive power compensation and other energy transformation, optimization system operation and control , improve overall system efficiency. The plan, in 2015 the motor system efficiency ratio in 2010 increased 2 to 3 percentage points , "Twelve Five " period formed 80 billion kwh of power saving capability. Therefore, the " Twelfth Five-Year " since the energy saving and environmental protection as the core of China's industrial economic development in the sustainable development of China's industry specified direction , while also effectively promote the sustainable development of our inverter industry , so that our inverter industry continue to expand market share in the industry , and with strong development strength to become China's industrial economic development an important basis points.
Frequency energy is mainly used in AC motor speed through the implementation of necessary changes , change the drive to achieve the mechanical properties of the production process requirements of the occasion, more applied in fan, water pump . When the motor is running at rated speed only , the drive mechanism may only be a rated speed. When the production process to adjust process parameters, can only increase ( decrease ) method to force change the flow resistance of the system , the motor is always running at rated conditions , resulting in waste of energy . Such as fans , pumps and other equipment The traditional way is by adjusting the governor exit ( or entrance ) of the baffle , the valve opening to adjust to the amount of wind and water supply , in addition to energy consumption in vain , but also increases the system accessories , but also increases probability of failure of the system . When using the inverter , if the flow requirements reduced, by reducing the pump or fan speed to meet the requirements .
On the whole, primarily through the inverter power factor compensation and soft-start two ways to achieve energy savings. Power factor compensation , due to reactive power will increase line losses and heating equipment , coupled with lower power factor resulting reduction in active power , reactive power consumption of a large number of lines which , inefficient equipment , waste. In the use of frequency control devices , the drive internal filter capacitor effect , thereby reducing the reactive power loss , increasing the active power grid .
Energy saving soft start motor hard start will cause serious impact on the grid , while the grid capacity requirements are too high, a large current at startup and vibration damper and valve when great damage to the equipment , the use of pipeline life is extremely unfavorable. The use of inverter soft start function , will make the starting current from scratch , reducing the impact on the grid and the power supply capacity requirements , to extend the service life of the equipment and valves , thus saving equipment maintenance costs.
But note that, in the frequency of use should be avoided , " small horse cart " problem. The cause of the problem is generated based on the current conditions of work put into the design restrictions that designed and installed to save money when many places have adopted the inverter power is less than the motor nominal power setting. But with technological development , technological production conditions change, " small horse cart " questions inevitably arise , causing the drive can not operate normally. Therefore, the inverter device probation period, preventive measures should be adjusted to detect in advance to avoid these problems. In addition , the inverter normally 6 years to 10 years after this easy to enter the high incidence of failure , they would often burn components , failure, malfunction protection functions such as the phenomenon of frequent moves , seriously affecting its normal operation.
Variable speed fans reduce power consumption of cement
Industry report: our inverter market is currently in a period of rapid growth in the textile machinery, air conditioning, elevators , metallurgical and other industries widely used. In the past few years, our inverter market to maintain a high growth rate . According to estimates, calculated in accordance with the needs of the market , at least after 10 years in order to saturate the market and gradually matured. Therefore, China inverter market has a broad space for development.
At present, China is vigorously promoting energy saving ideas , in 2012 inverter industry market segmentation of 6% is gradually resumed growth after shrinking , 4 trillion yuan investment in energy saving inverter industry to further stimulate market development . In the cement industry, for example , in cement plant mechanical and electrical equipment , centrifuges, water pump equipment, air compressor , separator , rotary kiln , ball mill, plate feeder , speed belt scales, feed coal cutter , grate cooler and kiln Roots blower , unloading machine and all necessary equipment on AC variable speed inverter can be used to achieve the energy saving function . Among them, the fan is adjusted by means of frequency control at home and abroad as energy is widely used in various industries , foreign cement companies have extensive use of variable speed wind turbines to meet different system regulating working conditions in order to reduce power consumption costs. Explore the potential to become a fan energy to enhance the market competitiveness of cement companies a big move .
