电机是一种应用量大、使用范围广的高耗能动力设备。据统计，我国电机耗电约占工业用电总量的60%～70%。实际应用中，我国电机的整体运行状况，同国外相比差距很大，机组效率约为75%，比国外低10%左右；系统运行效率为30～40%，比国际先进水平低20～30%。因此，我国的电机应用具有极大的节能潜力，推行电机节能势在必行。 Motor is a kind of are big, the wide use of energy intensive power equipment.According to statistics, China's electric power consumption accounts for about 60% ~ 70% of the total industrial power.In practical application, the overall health of the motor, a big gap compared with foreign, unit efficiency is about 75%, about 10% less than abroad;System efficiency is 30 ~ 40%, 20 ~ 30% lower than the international advanced level.Therefore, application of motor in our country has a great energy saving potential, promote motor energy conservation is imperative.
目前电机能耗状况是：与发达国家相比，我国电力能源利用效率仍然较低，尤其是工业用电设备电能消耗高，浪费情况较为严重。大量的工业设备如风机、泵类设备以及传统的工业缝纫机、机械加工设备等，多采用交流电动机恒速传动的方案运行，导致交流电动机效率普遍较低。 Motor energy consumption is at present: compared with the developed countries, our country electric power energy efficiency is still low, especially the industrial electric power consumption of the equipment are high, waste is serious.A large number of industrial equipment such as fans, pumps and traditional industrial sewing machines, mechanical processing equipment, with ac motor constant speed transmission scheme, operation result in ac motor efficiency is generally low.
传统的工业缝纫机电机是一款交流离合器电机，效率仅为40～50%；电机在工作时，不论缝制布料厚薄，始终全功率输出；在缝纫机待料待机时，电机通过离合器脱开负载，继续空载运行，造成极大的待机损耗。The traditional industrial sewing machine motor is an ac clutch motor, efficiency was only about 40 ~ 50%;Motor at work, regardless of sewing fabric thickness, always full power output;When sewing machine work on standby, motor by clutch release load, to continue running light, caused a great deal of standby loss.
根据美国能源部的一项数据显示，如果采用最新的高效率电机设备和一定的变频调速装置来替代旧的电机设备，工业用户至少能在现有基础上节省电能18%以上。目前许多国家均已指定流量压力控制必须采用变频调速装置取代传统方式，我国也在积极鼓励工业企业采用高效、节能的电动机、锅炉、窑炉、风机、泵类等设备。目前，我国在家电行业已逐步采用变频调速控制技术以降低能耗，而工业控制领域中的许多速度调节方法还停留在传统技术层面上。 According to the U.S. department of energy (doe), according to a data if using the latest equipment and high efficiency motor of variable frequency speed regulating device to replace the old machine equipment, based on the existing industrial users can at least save electric energy more than 18%.Now many countries have been specified flow pressure control variable frequency speed regulating device must be used to replace the traditional way, in our country are also actively encouraging industrial enterprises with high efficiency, energy saving motor, boilers, furnaces, fans, pumps and other equipment.At present, in the home appliance industry in China has gradually adopt frequency control of motor speed control technology to reduce energy consumption, and many in the field of industrial control speed regulation method with the traditional technology level.
在工业生产、产品加工制造业中，风机设备主要用于锅炉燃烧系统、烘干系统、冷却系统、通风系统等场合，根据生产需要对炉膛压力、风速、风量、温度等指标进行控制和调节以适应工艺要求和运行工况。而最常用的控制手段则是调节风门、挡板开度的大小来调整受控对象。这样，不论生产的需求大小，风机都要全速运转，不能随运行工况的变化进行相应的调节，白白浪费了大量的能量。在生产过程中，不仅控制精度受到限制，而且容易造成设备损耗，从而导致生产成本增加，设备使用寿命缩短，设备维护、维修费用居高不下。In industrial production, product processing and manufacturing, fan equipment is mainly used for boiler combustion system, drying system, cooling system, ventilation system, etc, according to the production needs of furnace pressure, wind speed, air volume, temperature indicators such as control and adjust to meet the technological requirements and operation condition.The most commonly used means of control is damper, the baffle opening to adjust the size of the controlled object.In this way, regardless of the demand of production size, the fan will run at full speed, cannot adjust accordingly along with the change of operation condition, a large amount of energy wasted.In the process of production, not only the control precision is restricted, and easy to cause loss of equipment, which can lead to the cost of production increases, the equipment service life is shortened, equipment maintenance, maintenance costs high.
泵类设备在生产领域同样有着广阔的应用空间，提水泵站、水池储罐给排系统、工业水(油)循环系统、热交换系统均使用离心泵、轴流泵、齿轮泵、柱塞泵等设备。根据不同的生产需求往往采用调整阀、回流阀、截止阀等节流设备进行流量、压力、水位等信号的控制。这样，不仅造成大量的能源浪费，管路、阀门等密封性能的破坏；还加速了泵腔、阀体的磨损和汽蚀，严重时损坏设备、影响生产、危及产品质量 Pump equipment also has a wide application in the field of production space, numerical station, tank storage tank to the exhaust system, industrial water (oil) circulation system, heat exchange system using centrifugal pump, axial flow pump, gear pump, plunger pump and other equipment.According to different production requirements often USES the adjusting valve and return valve, globe valve throttling devices such as flow, pressure, water level control signal.In this way, not only caused a lot of energy waste, the destruction of the pipeline, valve sealing performance;Also accelerated the pump cavity, the body of the wear and cavitation, serious damage to the equipment, affect production, and threaten the quality of the products
