1.空气压缩机油耗大
1. High oil consumption of air compressor
检查疏水阀排出的冷凝水含油量是否过大,压缩机油位是否偏高,小压力阀开启压力是否正常,回油管是否阻塞,油分离芯是否阻塞等。以上问题都会影响油耗,应及时处理。
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.空压机运行中自动停机
2. The air compressor stops automatically during operation
首先,检查机台是否正常自动停机;然后检查自动开关和热继电器是否动作,是否引起冷却风扇电机停止,或排气温度过高,或压力过高等,以及电机电压是否正常等。
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.空压机排气压力过低
3. The exhaust pressure of the air compressor is too low
首先,检查分离前后压力,手动阀和调节电磁阀2SV等是否漏气;然后检查用气管路有无泄漏,蝶阀是否全部打开,进气调节器是否工作正常,电磁阀3SV、8SV是否漏气,压力开关IPS是否需重新调整等。
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.空气压缩机启动不畅
4. The air compressor does not start smoothly
开机几秒钟后自动停机从电器方面人手,如自动空气开关是否起跳,电压是否正常,进气蝶阀关闭程度是否正常(压缩机是不能带负载启动的),以及Y一△启动中接触器和电机三相是否正常等。
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.空压机排气温度过高
5. The exhaust temperature of the air compressor is too high
排气温度一般在80~95℃。若没有足够润滑油冷却,则会使温度过高而引起故障。首先应检查环境温度、压缩机润滑油、油位、油质、冷冻风扇等是否正常;然后检查油冷却器、后冷却器是否清洁,温控阀元件、断油电磁阀电压和阀体部分是否正常,如有膜片损坏、温控阀芯不动作等,则需更换;查看油过滤器是否弄脏或需更换。
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.空气压缩机不供气
6. The air compressor does not supply air
检查控制油缸有无动作,如有动作,检查蝶阀有无机械故障;如无故障,查看加载电磁ISV线圈是否有吸力;排除ISV电磁阀机械故障和线圈故障后,再逐一排查电磁阀ISV所在的分电路。
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.空气压缩机进口喷油而停机
7. Shut down due to oil injection at the inlet of air compressor
先检查断油电磁阀5SV有无电压,机械部分是否正常;若正常,则检查止逆阀,进行重新装配或更换。
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.空气压缩机不能启动
8. The air compressor cannot be started
首先检查有无控制电压。若没有,则要检查熔丝等是否完好;如果有控制电压,则检查控制继电器及时间继电器运行是否正常
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
