螺杆空气压缩机排气含油故障介绍

1油分离芯子出现损坏

1 oil separation core is damaged.
在螺杆式空气压缩机的运行过程中,油分离芯子出现损坏如破损、穿孔现象,那么其就失去了油气分离的作用。也就是说混合气体和空气压缩机的排气管道直接贯通了,那么大量的冷却油并没有被分离出来,就会随着气体一起被排出机体,就造成了在排气过程中出现带油故障。
During the operation of screw air compressor, the oil separation core is damaged such as breakage and perforation, and then it loses the function of oil-gas separation. That is to say, the mixture gas and air compressor exhaust pipe directly through, then a large number of cooling oil has not been separated, will be exhausted with the gas together with the body, resulting in the exhaust process with oil failure.
2回油管路出现故障
2 failure of oil return line.
在螺杆式空气压缩机的工作过程中,回油管路肩负着重要的责任,油分离芯子内部与空气压缩机进口会形成一种压力差,在这种压力差的作用下,回油管路负责将油分离芯子的底部聚集的油输送回空气压缩机,在下个循环过程中继续使用。如果回油路出现堵塞、断裂以及安装不正确等故障,就不能将油分离芯子底部聚集的油输送回空气压缩机,造成底部积压的油过多,那么这部分未被输送回空气压缩机的油就将随着气体排出,就会出现排气过程中出现带油的现象。
In the working process of the screw air compressor, the oil return pipeline shoulders an important responsibility. The pressure difference between the oil separation core and the air compressor inlet forms. Under the action of this pressure difference, the oil return pipeline is responsible for transferring the oil gathered at the bottom of the oil separation core back to the air compressor and in the next cycle process. Continue to use. If the return circuit is blocked, broken and incorrectly installed, the oil gathered at the bottom of the oil separation core can not be transported back to the air compressor, resulting in excessive oil backlog at the bottom, then this part of the oil not transported back to the air compressor will be discharged with the gas, there will be oil during the exhaust process. Elephants.
3系统压力控制过低

3 system pressure control is too low.
在螺杆式空气压缩机的运行过程中,系统压力控制过低,将会造成分离器内的离心力小于工作要求离心力,那么分离器的作用就不会完全体现出来,就会造成进入下一环节分离器芯子内气体的含油量过高,超出了其分离范围,也就导致了油气分离不彻底,在空气压缩机排气过程中出现带油故障。
In the running process of screw air compressor, if the system pressure is too low, the centrifugal force in the separator will be less than the centrifugal force required by the work, then the function of the separator will not be fully embodied, and the oil content of the gas in the core of the separator will be too high to exceed the separation range. It also led to the incomplete separation of oil and gas, and there was an oil fault in the exhaust process of the air compressor.
4最小压力阀失效
4 minimum pressure valve failure
在螺杆式空气压缩机的运行过程中,最小压力阀的作用是保证运行过程中系统压力控制在最小压力之上。如果最小压力阀出现失效现象,那么系统的最小压力将无法保证,由于运气设备的耗气量是非常大的,就会造成系统压力过低,回油管路不能回油。聚集在油分离器芯子底部的油就将无法回送到空气压缩机内,会随着压缩气体排出空气压缩机,造成平排气过程中的带油故障。
In the operation process of screw air compressor, the function of minimum pressure valve is to ensure that the system pressure is controlled above the minimum pressure in the operation process. If the minimum pressure valve fails, then the minimum pressure of the system will not be guaranteed, because the gas consumption of the gas transport equipment is very large, it will cause the system pressure is too low, the return pipeline can not return oil. Oil gathered at the bottom of the oil separator core will not be able to return to the air compressor, with the compressed gas discharged from the air compressor, resulting in flat discharge process with oil fault.
5空气压缩机内加入的冷却油过多
5 too much cooling oil is added to the air compressor.
在螺杆式空气压缩机运行前,加入的冷却油过多,超过空气压缩机的范围,那么在空气压缩机的运行过程中,由于油位过高,虽然分离系统将油气分离出来了,但是在气体的排放中,气体还会将冷却油卷入到气体当中排放,致使排放气体中含油量过高,出现带油故障。
Before the screw air compressor runs, too much cooling oil is added, which is beyond the scope of the air compressor. During the operation of the air compressor, the oil level is too high, although the separation system separates the oil from the oil, but in the discharge of the gas, the gas will also take the cooling oil into the gas and discharge it into the gas. The oil content in the exhaust gas is too high and there is an oil fault.
6冷却油质量不合格
6 the quality of cooling oil is not qualified.
在空气压缩机运行前,加入了不合格的冷却油,或者冷却油超过了适用时间,已经无法达到冷却的效果。那么在螺杆式空气压缩机的运行过程中,冷却油失去了其作用,并不能将油气冷却分离。那么在排气过程中就必定会出现带油故障。
Before the air compressor runs, it can not achieve the cooling effect by adding unqualified cooling oil, or the cooling oil exceeds the applicable time. So in the operation process of screw air compressor, the cooling oil loses its role and can not separate the oil and gas cooling. Then there will be an oil fault in the exhaust process.
