山東空壓機節(jié)能的四個方面

空壓機變頻是根據負載變化，控制輸入的電壓頻率，保持壓力，流量，溫度等參數的穩(wěn)定，從而提高空壓機的工作性能。從以下四個方面可以讓空壓機更節(jié)能：

The frequency conversion of air compressor is to control the input voltage frequency according to the load change, keep the stability of pressure, flow, temperature and other parameters, so as to improve the working performance of air compressor. Air compressor can be more energy-saving from the following four aspects:

（1）運行成本降低——傳統(tǒng)空壓機的運行成本由三項組成：初始采購成本，成本維護狀語從句：能源。其中成本能源。成本大約占空壓機運行成本的77％通過能源成本降低44.3％，再加上空壓機變頻節(jié)能改造后對設備的沖擊減少，維護和維修量也會隨之減少，所以運行成本將大大降低。

(1) The operation cost of traditional air compressor consists of three parts: initial purchase cost, cost maintenance clause: energy. Among them, the cost of energy. The cost accounts for about 77% of the operating cost of the air compressor. The energy cost is reduced by 44.3%. In addition, the impact on the equipment will be reduced after the air compressor frequency conversion energy-saving transformation, and the maintenance and repair quantity will also be reduced, so the operation cost will be greatly reduced.

（2）降低空壓機噪音——根據空壓機的工況要求，空壓機變頻節(jié)能改造后，電機運轉速度明顯減慢，因此有效地降低了空壓機運行時的噪音。變頻技術在中國算是一種成熟的節(jié)能技術，近年來隨著同步永磁變頻空壓機的出現，已經取代了原來的外掛變頻技術，同并且普通變頻器比較具有明顯優(yōu)勢。

(2) Reduce the noise of air compressor: according to the working condition requirements of air compressor, after the energy-saving transformation of frequency conversion of air compressor, the running speed of motor is obviously slowed down, so the noise of air compressor is effectively reduced. Frequency conversion technology is a mature energy-saving technology in China. In recent years, with the appearance of synchronous permanent magnet frequency conversion air compressor, it has replaced the original external variable frequency technology, and has obvious advantages compared with ordinary frequency converter.

（3）提高壓力控制精度——變頻控制系統(tǒng)具有精確的壓力控制能力，使空壓機的空氣壓力輸出與用戶空氣系統(tǒng)所需的氣量相匹配?？刂谱冾l壓縮機的輸出氣量隨著電機工轉速的改變而改變。變頻由于控制電機工速度的精度提高，所以它可以使管網的系統(tǒng)壓力變化保持在3Pisg變化范圍，也就是0.2巴范圍內，有效地提高了工況質量。

(3) Improve the accuracy of pressure control - the frequency conversion control system has accurate pressure control ability, so that the air pressure output of the air compressor matches the air volume required by the user's air system. The output gas volume of variable frequency compressor changes with the change of motor speed. Due to the improvement of the accuracy of motor speed control, frequency conversion can keep the system pressure change in the range of 3pisg, i.e. 0.2 bar, which effectively improves the working condition quality.

（4）延長空壓機的使用壽命——空壓機變頻節(jié)能改造從0Hz時起動空壓機，它的起動加速時間可以調整，從而減少起動時對空壓機的電器部件和機械部件所造成的沖擊，增強系統(tǒng)的可靠性，使空壓機的使用壽命延長。此外，變頻控制能夠減少機組起動時電流波動，這一波動電流會影響電網和其它設備的用電，變頻器能夠有效值的將起動電流的峰值減少到低程度。

(4) Prolonging the service life of air compressor frequency conversion energy-saving transformation of air compressor starting air compressor from 0Hz, its starting acceleration time can be adjusted, so as to reduce the impact on the electrical and mechanical parts of the air compressor during starting, enhance the reliability of the system, and prolong the service life of the air compressor. In addition, frequency conversion control can reduce the current fluctuation when the unit starts, which will affect the power consumption of power grid and other equipment. The inverter can effectively reduce the peak value of starting current to a low level.
