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.

螺桿空壓機使用過程中常見報警：

Common alarms during the use of screw air compressor:

油過濾器：機組運行時空氣中的雜質(zhì)被吸入壓縮機后引起油過濾器臟堵塞，使油過濾器前后壓差過大，潤忽悠油無法按正常流量進入壓縮機引發(fā)機組高溫故障。所以當進出油壓差超過0.18MPa時應及時更換濾芯。

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.

機油氣分離器出現(xiàn)故障報警：從空壓機機頭出來的壓縮空氣會攜帶一部分的機油。大油滴通過油氣分離罐時易分離，而小油滴(直徑1um以下懸浮油微粒)則必須通過油氣分離濾芯的微米及玻纖濾料層過濾。當它太臟時，會影響潤忽悠循環(huán)，造成過熱停機。一般可以通過加載前后的壓差進行判斷，當兩端壓差為開空壓機之初時的3倍或z大壓差達到0.1MPa時，就應及時清理或更換。

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，指油氣分離器內(nèi)油位低，油位計內(nèi)看不到油。勤檢查發(fā)現(xiàn)油面低于檢視管下端時應立即進行補充。運行過程中低于油標中間位置也是要及時進行補充的。

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.

散熱不佳：油量、油質(zhì)不正常。

Poor heat dissipation: abnormal oil quantity and quality.

加卸載超機組運行壓力。

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

螺桿空壓機機組長時間高速運轉(zhuǎn)，容易出現(xiàn)油品老化結(jié)焦，潤滑油循環(huán)不暢，過濾器堵塞，壓縮空氣含水含油過多，高溫停機等問題，掌握常見故障解決措施可以幫我們縮短檢修時間。

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.
