                    空壓機排氣量與什么有關呢?

                    一、泄漏:轉子之間、轉子與外殼之間在工作運轉時都會有間隙,并非直接接觸的,所以就會發生氣體泄漏。壓力升高后的氣體通過間隙向吸氣管道及正在吸氣的嚙槽泄漏時,會導致排氣量減少。因此要讓泄露量最大化的少,在從動轉子的齒頂做有密封齒,主動轉子的齒根開有密封槽,端面加工環狀或條狀的密封齒。但是萬一密封線磨損,泄漏量也會增加,排氣量減少。

                    Leakage: there is a gap between the rotor, the rotor and the shell when it is working and running. It is not a direct contact, so gas leakage will occur. When the pressure increases, the gas will leak to the suction pipe and the suction grooved slot through the gap. Therefore, to minimize the amount of leakage, a sealing tooth is made on the top of the driven rotor, the root of the active rotor has a sealing groove, and the end of the rotor has a ring or strip seal. However, if the sealing line is worn, the leakage will also increase and the exhaust volume will decrease.
                    二、吸氣狀態:螺桿式壓縮機是容積型壓縮機,吸氣體積不變。當吸氣溫度升高,或吸氣管路阻力過大而讓吸入壓力降低時,氣體的密度減小,相應地會減少氣體排氣量。
                    Two, suction state: screw compressor is a volume compressor, suction volume unchanged. When the suction temperature increases or the suction line resistance is too large and the suction pressure decreases, the density of the gas decreases, which reduces the gas displacement accordingly.

                    三、冷卻效果:氣體在被壓縮時溫度便會升高,轉子和機殼的溫度也會隨之升高。在吸氣過程中,氣體會受到轉子和機殼的加熱而膨脹,減少吸量??諝鈮嚎s機的轉子有時候會采用油冷卻,機殼用水冷卻,主要的原因是讓溫度降下來。如果冷卻性差,溫度就會升高,排氣量減少。
                    Three, cooling effect: when the gas is compressed, the temperature will rise, and the temperature of the rotor and the shell will also rise. During the suction process, the gas is expanded by the heating of the rotor and the shell, reducing the suction. Sometimes the rotor of the air compressor is cooled by oil, and the shell is cooled by water. The main reason is that the temperature drops. If the cooling capacity is poor, the temperature will increase and the exhaust volume will decrease.
                    四、轉速:螺桿壓縮機的排氣量與轉速成正比。轉速會隨著隨電網的電壓、頻率而變化。當電壓降低(對異步電動機)或頻率降低時,轉速將下降,使氣量減少。
                    Four, rotate speed: the displacement of the screw compressor is directly proportional to the speed. The speed will vary with the voltage and frequency of the grid. When the voltage is reduced (asynchronous motor) or the frequency is reduced, the speed will decrease and the volume of gas will be reduced.
