During the process of replacing the fuel filter, high-pressure oil pipe, oil pump, etc. in the fuel system of the generator set, or when the fuel pipe is not sealed and the fuel is used up, the fuel system may enter the air during this period. If the air enters the fuel system, the unit will be difficult to start or the operation will be unstable, so it is necessary to exhaust the unit, so how to eliminate the air? Now let's introduce it to you by the editor of Cornwall.

一、排除空气的方法

1、 Method of removing air

1、一般情况下，用起子或扳手拧松喷油泵两侧上端的任一排气螺丝数圈。用手按压手动油泵15-20次，至排出的柴油连续通畅无气泡，发出“吱吱”的声音为止。拧死放气螺钉，将手动油泵按压回至原位。

1. Generally, loosen any exhaust screw at the upper end of both sides of the fuel injection pump with a screwdriver or wrench for several turns. Press the manual oil pump for 15-20 times until the discharged diesel oil is continuous and free of bubbles and makes a "squeak" sound. Tighten the vent screw and press the manual oil pump back to its original position.

2、如果手头没有打开喷油泵上放气螺钉的合适起子或扳手，可先拧开手油泵，然后松开从柴油滤清器至喷油泵之间的任何一个管接头，然后再通过反复按压手油泵至从该接头中排出通畅无气泡的油流即可，然后边按压手油泵边紧固该接头，然后再将手油泵揿压回原位即可。

2. If there is no suitable driver or wrench to open the vent screw on the fuel injection pump, first unscrew the hand oil pump, then loosen any pipe joint from the diesel filter to the fuel injection pump, and then press the hand oil pump repeatedly until a smooth and bubble free oil flow is discharged from the joint, then tighten the joint while pressing the hand oil pump, and then press the hand oil pump back to its original position.

3、如果手头无松开管路中接头的扳手时，可以通过反复的按压你的手油泵，至输油泵到喷油泵段低压油路压力足够高时，燃油从溢流阀中流入燃油回油管路，油路中的气体就会从溢流阀中排出。

3. If there is no wrench to loosen the connector in the pipeline, you can press your hand oil pump repeatedly until the pressure of the low-pressure oil path from the oil delivery pump to the fuel injection pump section is high enough, the fuel flows into the fuel return pipeline from the overflow valve, and the gas in the oil path will be discharged from the overflow valve.

4、如果在途中，需要排除油路中的空气，可以先松开喷油泵上的放气螺钉或松开柴油滤清器与喷油泵之间的任意一个接头，然后通过起动驱动机械输油泵。该漏点就会喷出通畅且无气泡的燃油，这时再拧紧松开的上述漏点就可以了。

4. If the air in the oil path needs to be removed on the way, loosen the bleed screw on the fuel injection pump or loosen any connector between the diesel filter and the fuel injection pump, and then drive the mechanical fuel transfer pump by starting. The leak point will eject unobstructed and bubble free fuel. At this time, it is OK to tighten the loosened leak point.

二、注意事项

2、 Precautions

1、不可在柴油机热机状态排气，燃油如果喷到炽热排气管上，将会造成火灾。

1. Do not exhaust when the diesel engine is hot. If fuel is sprayed on the hot exhaust pipe, it will cause a fire.

2、应防止高压燃油损伤皮肤。

2. High pressure fuel shall be prevented from damaging skin.

3、装有通电型断油阀的发电机组燃油系统的排气时，一定要先将控制屏内标。

3. When exhausting the fuel system of the generator set equipped with the energizing fuel cut-off valve, the control panel must be marked inside.

4、有“FCR”中间继电器上的按钮拔出后再开始排气操作，排气结束后要将“FCR”中间继电器上的按钮压下复位。

4. After the button on the "FCR" intermediate relay is pulled out, the exhaust operation can be started. After the exhaust, press the button on the "FCR" intermediate relay to reset.

5、油路排气时，用扳手拧松各处排气螺钉，上下扳动输油泵手柄泵油，直至出油中没有气泡后拧紧排气螺钉即可。

5. When the oil circuit is vented, loosen the vent screws with a wrench, pull the handle of the oil transfer pump up and down to pump oil until there are no bubbles in the oil outlet, and then tighten the vent screws.

6、一般经过低压油路的排除空气，机组就可启动。如还需要排除高压油管中的空气，松开高压油管在喷油器一端的螺帽，按压手动油泵，直至所溢出的燃油中无气泡后拧紧螺帽。如此逐缸进行，使各缸喷油器中充满燃油。

6. Generally, the unit can be started after the air is discharged through the low-pressure oil circuit. If it is necessary to remove the air from the high-pressure oil pipe, loosen the nut of the high-pressure oil pipe at one end of the fuel injector, press the manual oil pump until there are no bubbles in the spilled fuel, and then tighten the nut. This is done cylinder by cylinder so that the fuel injectors of each cylinder are filled with fuel.

7、如果气体仍不能排净，应检查管路是否有漏气情况。

7. If the gas cannot be discharged completely, check whether there is air leakage in the pipeline.
