1. Check the connecting bolts of the transmission structure, and tighten them if they are not tightened.

2、开启打气泵的排污阀。

2. Open the blowdown valve of the air pump.

3、检查离合器手柄压力是不是正常，超速保险装置有没有定位。

3. Check whether the clutch handle pressure is normal and whether the overspeed safety device is positioned.

4、检查循环水泵、燃油泵、机油泵有无异常。

4. Check whether the circulating water pump, fuel pump and oil pump are abnormal.

5、机房操作人员要遵守安全操作，穿工作服、绝缘鞋，人员要分工明确。

5. Machine room operators should abide by safe operation, wear work clothes and insulating shoes, and the division of labor should be clear.

6、把励磁电阻置于的电阻位置，并将送电开关关掉。

6. Put the excitation resistance at the maximum resistance position and turn off the power supply switch.

7、查看贮气瓶压力有无异常。

7. Check whether the pressure of the gas cylinder is abnormal.

8、将各系统管路闸门设置开启位置。

8. Set the opening position of each system pipeline gate.

9、查看飞轮和发电机部分防栏杆罩有没有损坏。

9. Check whether the guardrail cover of flywheel and generator is damaged.

10、检查变速箱、调速器、离合器、油位、这些紧固件是否完好，油水温度不得低于25度才可以启动。

10. Check whether the gearbox, governor, clutch, oil level and these fasteners are in good condition, and the oil-water temperature shall not be lower than 25 ℃.

启动和运行操作：

Start up and run operation:

1、对于停机超过25h的机组，要先打开试动阀，并启动机油泵，对于停机超过7天的机组，得先测量励磁机及操作电路的绝缘电阻。

1. For the unit shut down for more than 25 hours, the test run valve shall be opened and the oil pump shall be started. For the unit shut down for more than 7 days, the insulation resistance of exciter and operating circuit shall be measured first.

2、柴油发电机组运转之后，查看机油压力表的指示值，如果升到规定值以上必须停止机油泵且要关闭扫气泵排污阀，穿好前离合器螺钉。

2. After the diesel generator set is running, check the indicated value of the oil pressure gauge. If it rises above the specified value, the oil pump must be stopped, the drain valve of scavenging pump must be closed, and the front clutch screw shall be put on.

3、发动燃油泵放出管路中的空气，看看电压有没有在规定的值内，正常，才能进行正式启动。

3. Start the fuel pump to release the air in the pipeline, and check whether the voltage is within the specified value, and it can be started formally.

4、察看启动电源的电压有没有符合要求，若电压正常，可以启动按钮等发电机组正常运行后松开。

4. Check whether the voltage of the starting power supply meets the requirements. If the voltage is normal, the button can be released after the generator set operates normally.

5、发电机启动后，即发电机及全部电气设备都已带电，不得伸手接触带电部位。

5. After the generator is started, i.e. the generator and all electrical equipment have been charged, do not reach out to touch the live parts.

6、调整发电机组的转速，在调整时必须注意观察发电机运转有无异常，正常，集电环及换向器上的电刷，无跳动、无冒火花等情况且无异常响声。

6. When adjusting the speed of generator set, attention must be paid to observe whether the generator operates normally, whether the brush on the collector ring and commutator does not jump, sparkle and abnormal noise.

7、发电机启动后，应逐渐提高柴油发电机组的转速，并进行送电前的检查。

7. After the generator is started, the speed of the diesel generator set shall be gradually increased, and the inspection before power transmission shall be carried out.
