空压机在冬季如何进行保养？

在寒冷的冬季，由于气温较低，空压机一旦不注意保养服务的话，将引起设备故障。为此，在冬季，因为长时间停机，期间没有做防冻保护而造成冷却器冻裂和启动时机体故障等的情况不在少数。针对此种情况，为空压机用户提出以下几点空压机因冬季保养不当而引发故障的几点建议：

In cold winter, due to low temperature, once the air compressor does not pay attention to maintenance service, it will cause equipment failure. Therefore, in winter, because of the long-time shutdown and no antifreeze protection, there are not a few cases of cooler cracking and engine failure during start-up. In view of this situation, the following suggestions are put forward for air compressor users due to improper maintenance in winter:

1.停机较长时间或油滤使用时间较久的机器，开机前建议更换油过滤器，以防止刚开机时因油品粘稠穿透油滤能力下降造成机体供油不足使得机体启动时瞬间发热，造成机体故障；

1. For the machine that has been shut down for a long time or the oil filter has been used for a long time, it is suggested to replace the oil filter before starting up, so as to prevent the oil from being insufficient due to the viscosity of oil penetrating the oil filtration capacity when the machine is just started up, causing the engine block to heat up instantaneously when it is started up;

   
   

2.将设备断电后应用手盘动主机联轴器，应转动灵活，对于盘动困难的机体请不要盲目开机，应检查机体或电机是否有故障，润滑油是否粘稠失效等，故障排除后方可开机；

2. After the equipment is powered off, manually turn the main engine coupling, which should rotate flexibly. For the engine body with difficult turning, please do not start the machine blindly. Check whether the engine body or motor is faulty, whether the lubricating oil is viscous or not, etc. the machine can be started after troubleshooting;

3.空压机开机前应确保油温不低于+2度，若温度过低，请采用加热装置对油气桶和主机部位加热；

3. Before starting the air compressor, ensure that the oil temperature is not lower than + 2 ℃. If the temperature is too low, please use the heating device to heat the oil and gas barrel and the main engine;

4.检查油位在正常位置，检查所有冷凝水排放口已关闭（长期停机应打开），水冷机组还应检查冷却水排放口是否关闭（长时间停机时此阀门应打开）；

4. Check that the oil level is at the normal position, check that all condensate drain outlets have been closed (open for long-term shutdown), and check whether the cooling water discharge outlet is closed (the valve should be opened in case of long-term shutdown);

5.两级压缩机器特别是大功率的机型，停机一段时间后再次开机时，需在进气口加入适量润滑油并点动2-3次，且将油气桶机体的注油调节阀在刚启动时要全部打开，运行稳定后如排气温度过低，可调节客户冷却水阀门的进水量来控制温度，如有必要再根据实际温度情况，通过调节注油阀门来控制进油量达到合适的排气温度；

5. When the two-stage compression machine, especially the high-power machine, is shut down for a period of time, it is necessary to add appropriate amount of lubricating oil at the air inlet and jog it for 2-3 times, and the oil injection regulating valve from the oil-gas barrel to the body should be opened at the beginning. After stable operation, if the exhaust temperature is too low, the water inflow of the cooling water valve of the customer can be adjusted to control the temperature. If necessary, the actual temperature can be adjusted At the same time, adjust the oil injection valve to control the amount of oil to reach the appropriate exhaust temperature;

6.变频机要主意在冬季的排气温度，防止过低（主要是长时间低频运行造成排气温度过低），根据排气温度调节合适的冷却水水阀的开度，如确实有必要则可以更换为高温型热控制阀芯，避免油品的乳化；

6. Pay attention to the exhaust temperature of frequency converter in winter to prevent too low exhaust temperature (mainly caused by low frequency operation for a long time). Adjust the opening of cooling water valve according to the exhaust temperature. If necessary, it can be replaced by high temperature thermal control valve core to avoid oil emulsification;

7.若已安装热回收的机器，请关闭热回收系统的油路阀门，等机组运行正常后再缓慢开启热回收系统的油路控制阀门；

7. If the heat recovery machine has been installed, please close the oil circuit valve of the heat recovery system, and slowly open the oil circuit control valve of the heat recovery system after the unit operates normally;

8.以上工作检查后，空压机次开机应作一点动运行，检查运行情况及机体启动时声音是否正常。若温度突变请立即停机检查，切勿频繁启动机器，如有必要向机体内添加适量冷却液。

8. After the above work inspection, the air compressor should be started for the first time by inching to check the operation and whether the sound is normal when the body is started. If the temperature changes suddenly, please stop the machine immediately for inspection. Do not start the machine frequently. If necessary, add proper amount of coolant to the body.
