Air compressor is widely used in various fields, air compressor because of motor power and the length of the main shaft, exhaust volume will have size, air compressor exhaust volume is insufficient for many reasons.

用戶剛不知道自己生產(chǎn)的具體用氣情況，大概的選型，這時排氣壓力上不來，低于額定的排氣壓力，不能滿足用氣要求。這時候，可以檢查一下，管路是否有漏氣點(diǎn)。

The user just didn't know the specific gas consumption of their own production, and the general type selection, at this time, the exhaust pressure can't come up, which is lower than the rated exhaust pressure, and can't meet the gas requirements. At this time, you can check whether there are air leakage points in the pipeline.

關(guān)閉儲氣罐后面的閥門，如果機(jī)組能夠很快的升上壓力，開開閥門，壓力很快下降，并在一個壓力點(diǎn)，這就可以確認(rèn)，空壓機(jī)機(jī)組選型過小，機(jī)組排氣量小于生產(chǎn)的實(shí)際用氣量。

Close the valve behind the air storage tank, if the unit can quickly increase the pressure, open the valve, the pressure will drop quickly, and at a pressure point, it can be confirmed that the air compressor unit selection is too small, and the unit exhaust volume is less than the actual production gas consumption.

空壓機(jī)組使用一段時間后，氣量明顯不夠，壓力上不了，維持在額定用氣的下線位置。這時候，應(yīng)該檢查是否有新增的用氣設(shè)備，如果有新增的用氣設(shè)備，用氣量是多少，對比空壓機(jī)組看能否滿足要求，如不能，請并上新的空壓機(jī)組，增加排氣量。

After the air compressor unit has been used for a period of time, the air volume is obviously insufficient and the pressure can not be increased, so it is maintained at the offline position of rated gas consumption. At this time, we should first check whether there are new gas equipment, if there are new gas equipment, how much gas is used, compare with the air compressor unit to see whether it can meet the requirements, if not, please add a new air compressor unit to increase the exhaust volume.

如果沒有新增用氣設(shè)備，排氣量還是不夠，先檢查管路的漏氣情況，如果管路沒有漏氣點(diǎn)，那就是空壓機(jī)組本身的問題。

If there is no new gas equipment, the exhaust volume is still not enough. First check the air leakage of the pipeline. If there is no air leakage point in the pipeline, it is the problem of the air compressor unit itself.

空壓機(jī)組本身的排氣量不足原因：

The causes of insufficient exhaust volume of air compressor unit itself are as follows:

一，保養(yǎng)是否及時

1、 Is the maintenance timely

空壓機(jī)排氣量下降，排除以上可能后，看空壓機(jī)是否已經(jīng)保養(yǎng)，保養(yǎng)多久了，如果環(huán)境不是很理想，空壓機(jī)運(yùn)行2000小時應(yīng)檢查空濾是否堵塞，輕者可以用壓縮氣除塵，堵塞嚴(yán)重，更換新的空濾。很多時候，空壓機(jī)排氣量下降，沒有什么大的問題，就是疏于保養(yǎng)，空壓機(jī)空濾堵塞導(dǎo)致，更換新空濾后，正常使用。另外，除空濾外，潤滑液和其他濾芯也很關(guān)鍵，檢查潤滑液是否在標(biāo)準(zhǔn)范圍之內(nèi)，如缺少，請適當(dāng)添加。

If the air compressor is running for 2000 hours, check whether the air filter is blocked. If the blockage is serious, replace it with a new one. Most of the time, the air compressor exhaust volume drops, there is no big problem, that is, neglect of maintenance, air filter blockage caused by the air compressor, replace the new air filter, normal use. In addition, in addition to the air filter, lubricating fluid and other filter elements are also very important. Check whether the lubricating fluid is within the standard range. If it is missing, please add it appropriately.

二，進(jìn)氣閥是否完全打開

2、 Is the intake valve fully open

空壓機(jī)排氣量下降，檢查機(jī)組，剛剛保養(yǎng)，排除三濾和油品問題，這是檢查空壓機(jī)進(jìn)氣閥，拆下進(jìn)氣軟管，開啟空壓機(jī)，觀看進(jìn)氣閥的開口度是否正常。進(jìn)氣閥理論設(shè)計使用壽命是動作10萬次，因每個廠家使用批次不同，質(zhì)量也有所差異，所以進(jìn)氣閥出現(xiàn)故障可能導(dǎo)致機(jī)組排氣量下降。

When the air compressor's exhaust volume drops, check the unit, just after maintenance, eliminate the three filters and oil problems. This is the first step to check the air compressor's intake valve, remove the intake hose, open the air compressor, and watch whether the opening of the intake valve is normal. The theoretical design service life of the intake valve is 100000 times. Due to different brands and batches of each manufacturer, the quality is also different, so the failure of the intake valve may lead to the decrease of the unit's exhaust volume.

如果空壓機(jī)加載時進(jìn)氣閥不能全部打開，可以斷定，排氣量下降是進(jìn)氣閥故障，應(yīng)拆下檢修或是更換。

If the air inlet valve cannot be fully opened when the air compressor is loaded, it can be concluded that the decrease of exhaust volume is the fault of the air inlet valve, which should be removed for maintenance or replacement.

三，電機(jī)故障

3、 Motor fault

以上排除進(jìn)氣閥故障后，機(jī)組排氣量仍然沒有改變，應(yīng)考慮電機(jī)是否故障，由于電機(jī)線圈中發(fā)生局部短路，或者是軸承磨損，導(dǎo)致電機(jī)轉(zhuǎn)速低于額定轉(zhuǎn)速，使空壓機(jī)排氣量下降，應(yīng)檢修電機(jī)線圈，軸承等，修復(fù)后測試空壓機(jī)排氣量。

After the above troubleshooting of the intake valve, the exhaust volume of the unit still remains unchanged. Whether the motor is faulty or not should be considered. The motor speed is lower than the rated speed due to local short circuit in the motor coil or bearing wear, resulting in the decrease of the exhaust volume of the air compressor. The motor coil and bearing should be repaired, and the exhaust volume of the air compressor should be tested after repair.

四，環(huán)境改變，導(dǎo)致排氣量下降

4、 The environment changes, resulting in a decrease in exhaust volume

海拔升高，環(huán)境變的潮濕，都可能導(dǎo)致機(jī)組排氣量下降。海拔越高，空氣越稀薄，單位時間內(nèi)產(chǎn)氣量越小，空氣中水分過分，壓縮空中含有大量水分，在后部處理中，水蒸氣析出，導(dǎo)致排氣量減小。

The increase of altitude and the humidity of environment may lead to the decrease of unit exhaust volume. The higher the altitude is, the thinner the air is, and the smaller the gas production per unit time is. There is too much water in the air, and there is a lot of water in the compressed air. In the rear treatment, water vapor is separated out, which leads to the reduction of the exhaust volume.
