螺杆空压机常见故障排除
Common troubleshooting of screw air compressor
1.机器不启动：检查主开关及电源线、检查电机；
1. The machine does not start: check the main switch and power line, and check the motor;
2.开机后机器不加载：调整压力开关整定值或更换压力开关、检查或更换电磁阀；
2. The machine is not loaded after startup: adjust the setting value of the pressure switch or replace the pressure switch, check or replace the solenoid valve;
3.压缩机不卸荷，安全阀泄放：调整压力开关整定值或更换压力开关、检查或更换电磁阀；
3. The compressor is not unloaded and the safety valve is discharged: adjust the setting value of the pressure switch or replace the pressure switch, check or replace the solenoid valve;
4.油耗过多：按推荐用油、降低油位至正常位置、拆下回油管路清洗、更换油气分离器滤芯；
4. Excessive oil consumption: use the recommended oil, lower the oil level to the normal position, remove the oil return pipeline for cleaning, and replace the filter element of the oil-gas separator;
5.排气压力低于规定值：减少用气量或增加压缩机、检查系统泄漏、清理或更换进气过滤器芯、更换油气分离器滤芯、检查或更换电磁阀、检修进气控制阀、更换皮带、调整压力开关整定值；
5. The exhaust pressure is lower than the specified value: reduce the air consumption or increase the compressor, check the system leakage, clean or replace the air inlet filter core, replace the oil-gas separator filter element, check or replace the solenoid valve, repair the air inlet control valve, replace the belt, adjust the setting value of the pressure switch;
6.压缩机高温保护停机：改善环境通风条件、清扫或清洗冷却器、添油至规定位置、更换机油过滤器；
6. Compressor high temperature protection shutdown: improve the environmental ventilation conditions, clean or clean the cooler, add oil to the specified position, and replace the oil filter;
7.压缩机卸荷运行，排气压力仍缓慢上升，安全阀泄放：检查或更换电磁阀、检修进气控制阀、检修卸荷管道；
7. When the compressor is unloaded, the exhaust pressure is still rising slowly, and the safety valve is discharged: check or replace the solenoid valve, overhaul the air inlet control valve and overhaul the unloading pipeline;
8.安全阀泄放：检修或更换安全阀、检修最小压力阀、更换油气分离器滤芯、检修或更换压力开关、检查进气控制阀或电磁阀。
8. Relief of safety valve: maintenance or replacement of safety valve, maintenance of minimum pressure valve, replacement of oil-gas separator filter element, maintenance or replacement of pressure switch, inspection of air inlet control valve or solenoid valve.
