There will be signs before the failure of screw air compressor, such as abnormal sound during unit operation, high temperature, oil leakage, increased oil consumption, etc. Some phenomena are not easy to detect, which requires us to do a good job in daily inspection. Below, Shandong screw air compressor manufacturer will list the fault alarm causes and treatment measures during the operation of the unit.

螺杆空压机使用过程中常见报警：

Common alarms during the use of screw air compressor:

油过滤器：机组运行时空气中的杂质被吸入压缩机后引起油过滤器脏堵塞，使油过滤器前后压差过大，润忽悠油无法按正常流量进入压缩机引发机组高温故障。所以当进出油压差超过0.18MPa时应及时更换滤芯。

Oil filter: when the unit is running, the impurities in the air are sucked into the compressor, causing the oil filter to be dirty and blocked, so that the pressure difference between the front and back of the oil filter is too large, and the lubricating oil cannot enter the compressor according to the normal flow, resulting in the high temperature fault of the unit. Therefore, when the inlet and outlet oil pressure difference exceeds 0.18mpa, the filter element shall be replaced in time.

机油气分离器出现故障报警：从空压机机头出来的压缩空气会携带一部分的机油。大油滴通过油气分离罐时易分离，而小油滴(直径1um以下悬浮油微粒)则必须通过油气分离滤芯的微米及玻纤滤料层过滤。当它太脏时，会影响润忽悠循环，造成过热停机。一般可以通过加载前后的压差进行判断，当两端压差为开空压机之初时的3倍或z大压差达到0.1MPa时，就应及时清理或更换。

Fault alarm of oil-gas separator: the compressed air from the air compressor head will carry part of the oil. Large oil droplets are easy to separate when passing through the oil-gas separation tank, while small oil droplets (suspended oil particles with a diameter of less than 1um) must be filtered through the micron and glass fiber filter material layer of the oil-gas separation filter element. When it is too dirty, it will affect the lubrication cycle and cause overheating shutdown. Generally, it can be judged by the pressure difference before and after loading. When the pressure difference at both ends is 3 times that at the beginning of opening the air compressor or Z large pressure difference reaches 0.1MPa, it shall be cleaned or replaced in time.

油位低，指油气分离器内油位低，油位计内看不到油。勤检查发现油面低于检视管下端时应立即进行补充。运行过程中低于油标中间位置也是要及时进行补充的。

Low oil level means that the oil level in the oil-gas separator is low and no oil can be seen in the oil level gauge. If the oil level is lower than the lower end of the inspection pipe, it shall be supplemented immediately. During operation, the position lower than the middle of the oil standard shall also be supplemented in time.

散热不佳：油量、油质不正常。

Poor heat dissipation: abnormal oil quantity and quality.

加卸载超机组运行压力。

The loading and unloading exceeds the operating pressure of the unit.

螺杆空压机机组长时间高速运转，容易出现油品老化结焦，润滑油循环不畅，过滤器堵塞，压缩空气含水含油过多，高温停机等问题，掌握常见故障解决措施可以帮我们缩短检修时间。

Screw air compressor runs at high speed for a long time, which is prone to oil aging and coking, poor lubricating oil circulation, filter blockage, too much water and oil in compressed air, high temperature shutdown and other problems. Mastering common fault solutions can help us shorten the maintenance time.
