1.空氣壓縮機油耗大
1. High oil consumption of air compressor
檢查疏水閥排出的冷凝水含油量是否過大,壓縮機油位是否偏高,小壓力閥開啟壓力是否正常,回油管是否阻塞,油分離芯是否阻塞等。以上問題都會影響油耗,應(yīng)及時處理。
Check whether the oil content of condensate discharged from the drain valve is too large, whether the oil level of the compressor is high, whether the opening pressure of the small pressure valve is normal, whether the oil return pipe is blocked, whether the oil separation core is blocked, etc. The above problems will affect fuel consumption and should be handled in time.
2.空壓機運行中自動停機
2. The air compressor stops automatically during operation
,檢查機臺是否正常自動停機;然后檢查自動開關(guān)和熱繼電器是否動作,是否引起冷卻風扇電機停止,或排氣溫度過高,或壓力過高等,以及電機電壓是否正常等。
First, check whether the machine stops normally and automatically; Then check whether the automatic switch and thermal relay act, whether it causes the cooling fan motor to stop, or the exhaust temperature is too high, or the pressure is too high, and whether the motor voltage is normal.

3.空壓機排氣壓力過低
3. The exhaust pressure of the air compressor is too low
,檢查分離前后壓力,手動閥和調(diào)節(jié)電磁閥2SV等是否漏氣;然后檢查用氣管路有無泄漏,蝶閥是否全部打開,進氣調(diào)節(jié)器是否工作正常,電磁閥3SV、8SV是否漏氣,壓力開關(guān)IPS是否需重新調(diào)整等。
First, check whether the pressure before and after separation, manual valve and regulating solenoid valve 2sv leak; Then check whether the gas pipeline leaks, whether all butterfly valves are opened, whether the air inlet regulator works normally, whether the solenoid valves 3sv and 8sv leak, whether the pressure switch IPS needs to be readjusted, etc.
4.空氣壓縮機啟動不暢
4. The air compressor does not start smoothly
開機幾秒鐘后自動停機從電器方面人手,如自動空氣開關(guān)是否起跳,電壓是否正常,進氣蝶閥關(guān)閉程度是否正常(壓縮機是不能帶負載啟動的),以及Y一△啟動中接觸器和電機三相是否正常等。
After starting up for a few seconds, it will stop automatically from the electrical aspects, such as whether the automatic air switch jumps, whether the voltage is normal, whether the closing degree of the inlet butterfly valve is normal (the compressor cannot be started with load), and whether the three phases of the contactor and motor are normal during Y-delta startup.
5.空壓機排氣溫度過高
5. The exhaust temperature of the air compressor is too high
排氣溫度一般在80~95℃。若沒有足夠潤滑油冷卻,則會使溫度過高而引起故障。應(yīng)檢查環(huán)境溫度、壓縮機潤滑油、油位、油質(zhì)、冷凍風扇等是否正常;然后檢查油冷卻器、后冷卻器是否清潔,溫控閥元件、斷油電磁閥電壓和閥體部分是否正常,如有膜片損壞、溫控閥芯不動作等,則需更換;查看油過濾器是否弄臟或需更換。
The exhaust temperature is generally 80 ~ 95 ℃. If there is not enough lubricating oil for cooling, the temperature will be too high and cause failure. First, check whether the ambient temperature, compressor lubricating oil, oil level, oil quality and refrigeration fan are normal; Then check whether the oil cooler and aftercooler are clean, whether the temperature control valve element, oil cut-off solenoid valve voltage and valve body are normal. If the diaphragm is damaged and the temperature control valve core does not act, it needs to be replaced; Check whether the oil filter is dirty or needs to be replaced.
6.空氣壓縮機不供氣
6. The air compressor does not supply air
檢查控制油缸有無動作,如有動作,檢查蝶閥有無機械故障;如無故障,查看加載電磁ISV線圈是否有吸力;排除ISV電磁閥機械故障和線圈故障后,再逐一排查電磁閥ISV所在的分電路。
Check whether the control oil cylinder acts. If so, check whether the butterfly valve has mechanical failure; If there is no fault, check whether the loading electromagnetic ISV coil has suction; After eliminating the mechanical fault and coil fault of ISV solenoid valve, check the sub circuit of ISV solenoid valve one by one.
7.空氣壓縮機進口噴油而停機
7. Shut down due to oil injection at the inlet of air compressor
先檢查斷油電磁閥5SV有無電壓,機械部分是否正常;若正常,則檢查止逆閥,進行重新裝配或更換。
First check whether the oil cut-off solenoid valve 5sv has voltage and whether the mechanical part is normal; If normal, check the check valve and reassemble or replace it.
8.空氣壓縮機不能啟動
8. The air compressor cannot be started
檢查有無控制電壓。若沒有,則要檢查熔絲等是否完好;如果有控制電壓,則檢查控制繼電器及時間繼電器運行是否正常
First check for control voltage. If not, check whether the fuse is intact; If there is control voltage, check whether the control relay and time relay operate normally
