空壓機為什么會耗能嚴重？

一般來說，購置一臺空壓機投入使用，所需的費用包括兩個部分，一部分是購買成本和維護成本，這個占總費用的20%；另一部分是空壓機運行中的能源消耗，這個占到了空壓機使用費用的80%，可見空壓機的耗能十分嚴重。但是空壓機為什么耗能這么嚴重呢？主要有如下幾個方面原因。

Generally speaking, the cost of purchasing an air compressor to put into use includes two parts, one is the purchase cost and maintenance cost, which accounts for 20% of the total cost; the other is the energy consumption in the operation of the air compressor, which accounts for 80% of the use cost of the air compressor. It can be seen that the energy consumption of the air compressor is very serious. But why does the air compressor consume so much energy? The main reasons are as follows.

1、空壓機在運行時，使用最合適的電壓工作，電源電壓不對稱或電壓過高過低都會導致空壓機能源的大量浪費。由于三相四線制低壓供電系統(tǒng)單相負荷的不平衡，使得電動機的三相電壓不對稱，電機產(chǎn)生負序轉矩，增大電機的三相電壓不對稱，電機產(chǎn)生負序轉矩，增大電機運行中的損耗。另外電網(wǎng)電壓長期偏低，使得正常工作的電機電流偏大，因而損耗增大，三相電壓不對稱度越大，電壓越低，則損耗越大。

1. When the air compressor is running, using the most appropriate voltage to work, asymmetric power supply voltage or too high or too low voltage will lead to a lot of waste of air compressor energy. Due to the unbalanced single-phase load of the three-phase four wire low-voltage power supply system, the three-phase voltage of the motor is asymmetric, and the motor produces negative sequence torque, which increases the three-phase voltage asymmetry of the motor, and the motor produces negative sequence torque, which increases the loss in the operation of the motor. In addition, the long-term low voltage of the power grid makes the current of the normal motor larger, so the loss increases. The greater the three-phase voltage asymmetry, the lower the voltage, the greater the loss.

2、空壓機維修保養(yǎng)以及管理不善，空壓機在運行了一定周期后，便需要做定期的保養(yǎng)維護，若是配件出現(xiàn)了偏差問題，則需要及時的維修或是更換。如果對電機及設備沒有按照要求進行維修保養(yǎng)，任其長期運行，不但會效率低下，而且會使得損耗不斷增大。

2. Air compressor maintenance and poor management, air compressor in operation after a certain period, you need to do regular maintenance, if there is a deviation of parts, you need timely repair or replacement. If the motor and equipment are not maintained according to the requirements, it will not only be inefficient, but also increase the loss.

3、空壓機的電機負載率低，可能因為電動機選擇不當，富裕量過大或生產(chǎn)工藝變化，使得電動機的實際工作負荷遠小于額定負荷，大約占裝機容量30%~40%的電動機在30%~50%的額定負荷下運行，運行效率過低，但是能源消耗卻沒有減少，導致了大量的能源浪費。

3. The motor load rate of air compressor is low, which may be due to improper motor selection, excessive surplus or production process change, so that the actual working load of the motor is far less than the rated load. About 30% ~ 40% of the installed capacity of the motor runs under 30% ~ 50% of the rated load, the operation efficiency is too low, but the energy consumption is not reduced, resulting in a lot of energy waste.

4、已經(jīng)過時的老舊電機仍在使用，這些電機的制作工藝較為粗糙，但是技術不如現(xiàn)在，采用的是E級絕緣，導致體積較大，啟動性能差，效率低下，花費的能源好工作效率不成正比，也是空壓機耗能嚴重的原因之一。

4. The outdated old motors are still in use. The manufacturing process of these motors is relatively rough, but the technology is not as good as it is now. The E-Class insulation is used, which leads to large volume, poor starting performance, low efficiency, good energy consumption, and the work efficiency is not proportional. It is also one of the reasons for the serious energy consumption of the air compressor.
