1、在水泵排气堵头端加装排气管，排气管宜通往储液罐，并设置电动阀，电动阀在水泵启动前开启，开启时间以调试期间排气时间作为参考值，排气结束后关闭电动阀，启动水泵(储液罐液位高度必须高于水泵)，电动排气阀需要考虑防爆需求。

1. Install an exhaust pipe at the pump's exhaust plug end. The exhaust pipe should lead to the storage tank and have an electric valve. Open the valve before starting the pump, using the exhaust time from the debugging period as a reference. Close the valve after exhaust is complete, then start the pump. The storage tank level must be higher than the pump. The electric exhaust valve should meet explosion-proof requirements.

2、泵前管道管径设置需校核水泵汽蚀余量，如果设置有过滤器(<0.5mm)，需要考虑过滤器对其影响。

 -  抬高储液罐

 - 在运行一段时间后拆除过滤器滤芯

 - 选用低汽蚀余量水泵

 - 注意控制流量

2. Check the pump inlet pipe diameter against the pump's Net Positive Suction Head (NPSH) requirements. If a filter (<0.5mm) is installed, consider its impact.

    - Raise the storage tank.

    - Remove the filter element after some operation time.

    - Choose a pump with low NPSH requirements.

- Control the flow rate carefully.

3、在初期调试期间，需人工多次排气，并且记录排气时间和排气间隔。

3. During initial debugging, manually exhaust air multiple times and record the exhaust time and intervals.

4、水泵启动后需注意出口端压力表或压力变送器读数，如果发现明显压力异常，应立即停机检查，首先确认是否存在积气现象，同时观察水泵是否存在异响等故障现象，也可以通过控制器设定报警，防止故障发生。

4. After starting the pump, monitor the pressure gauge or pressure transmitter readings at the outlet. If abnormal pressure is detected, stop the pump immediately. Check for air accumulation and other faults, and consider setting up alarms via the controller.

5、严格限制水泵流量，避免过流现象发生。

 - 可以通过出口阀门调整

 - 可以通过变频器频率设定调整(根据发动机背压事实调节变频器或者控制器的压力设定值)

5. Strictly limit the pump flow rate to prevent overcurrent.

    - Adjust using the outlet valve.

- Adjust the pressure setting value of the frequency converter or controller according to the actual back pressure of the engine.

6、储液罐是否可以适当提高压力，改善水泵吸入口条件。

6. Consider slightly pressurizing the storage tank to improve suction conditions at the pump inlet.

7、在系统排空第二次启动之前需要重复检查上述步骤

7. Repeat all checks before restarting after the system purge.
