都说变频器可以节电是真的吗？
在不影响使用的前提下，进行合理调节，将不合理运行参数所消耗电能节省下来，就是所谓的经济运行，所说的节电。主要有几下几种情况：
Without affecting the use of premise, reasonable adjustment will save the energy consumed by unreasonable operation parameters, that is, the so-called economic operation, said power saving. There are several main situations:
1.变频器厂家表示，节电与否是个对比的结果，若以前是用阀门人工方式来对运行做调整，那么使用变频器后能多节电达20%～30%，还提高了工作效率，降低出错率。
1. Inverter manufacturers say that power saving is a comparative result. If the valve is used to adjust the operation manually before, the power saving can reach 20%-30% after using the converter. It also improves the work efficiency and reduces the error rate.
2.当电动机负载率达到10%～90%时，节电率顶多约8%～10%，也就是说负载率低，随之节电率就会高点。
2. When the motor load rate reaches 10%-90%, the maximum power saving rate is about 8%-10%. That is to say, the low load rate will lead to the high power saving rate.
3.其实是与实际的工况有关。比如说：大型的脱水机，转速变化比较大，省电效果也明显，又比如说，鼓风机冷却，要不停地变化风速。而如果压力、流量、转速比较恒定的话，不用有多大的变化，节电都不明显。 4.与使用方的运用方式也有关，选产品电耗大的、产品成本高的、或者调速方式不当的来使用变频器，这效果自然是显而易见的。5.变频器厂家表示，电机的工作方式也是一个条件。很容易理解，连续运转、短时间运转、间歇式运转，自然节电率是有所差距的。6.电动机工作时间长短也是一个条件。比如，一天开足24小时，一年开够365天的，节电量是会很大。7.电动机本身功率大小的影响。相同节电率下，功率大，则节电量会高，成正比关系，尽管节电率比起小功率时要低，但是实际效益仍旧很高。8.与原本使用调速方式有关系。打个比方，原先用滑差电动机调速，因调速效率低，效率在50%以下，非常浪费，而使用变频器调速后，就省下了这部分电。厂家呼吁更多生产厂家要重视变频器的运用。
3. Actually, it is related to the actual working conditions. For example: large-scale dehydrator, the speed change is relatively large, power saving effect is also obvious, for example, blower cooling, to constantly change the wind speed. If the pressure, flow rate and speed are relatively constant, there is no need to change much, and the power saving is not obvious. 4. It is also related to the user's mode of use. It is obvious to choose the products with high power consumption, high product cost or improper speed regulation to use the frequency converter. 5. Inverter manufacturers said that the working mode of the motor is also a condition. It is easy to understand that there is a gap in the rate of natural power saving between continuous operation, short-term operation and intermittent operation. 6. The working dingzhou.37ix.com.cntangshan.37ix.com.cnchengde.37ix.com.cnlangfang.37ix.com.cntime of the motor is also a condition. For example, if you drive 24 hours a day and 365 days a year, you will save a xingtai.37ix.com.cnhengshui.37ix.com.cnlot of electricity. 7. The influence of the power of the motor itself. At the same power-saving rate, if the power is large, the power-saving will be higher, which is proportional to the power-saving rate. Although the power-saving rate is lower than that of low power, the actual benefit is still very high. 8. It is related to the original use of speed regulation. For example, the original slip motor speed regulation, because of the low efficiency of speed regulation, the efficiency is less than 50%, very wasteful, and the use of frequency converter speed regulation, it saves this part of the electricity. Manufacturers appeal to more manufacturers to pay attention to the use of frequency converters.
