燃氣發電機組的起動系統包括起動馬達、蓄電池、起動繼電器、起動開關和起動按鈕。起動馬達通過導線依次與起動繼電器、蓄電池的正極相連；電源負極則與起動開關相連，以實現搭鐵；繼電器則由起動按鈕控制。由此，可從以下部分進行故障排查。

The starting system of the gas generator set includes a starting motor, a battery, a starting relay, a starting switch and a starting button. The starting motor is connected with the starting relay and the positive electrode of the battery in turn through wires; The negative pole of the power supply is connected to the start switch to realize grounding; The relay is controlled by the start button. Therefore, troubleshooting can be performed from the following parts.

（1）檢查蓄電池電壓：發電機使用的是24V鉛酸起動蓄電池。使用萬用表測量蓄電池電壓，正常應保持在25～28V之間，如果電壓低于正常范圍，將導致發動機起動轉速低于l10～180r／min的正常標準，點火控制器不能發出點火指令，發動機就無法起動。

(1) Check the battery voltage: the generator uses 24V lead-acid starting battery. Use a multimeter to measure the battery voltage, which should normally be kept between 25-28v. If the voltage is lower than the normal range, the engine starting speed will be lower than the normal standard of l10-180r / min. if the ignition controller fails to send the ignition command, the engine will not start.

（2）檢查連接導線緊固：燃氣發電機在運行時，機體本身產生震動，使蓄電池至起動馬達間連接線松動或脫落。

(2) Check the fastening of connecting wires: when the gas generator is running, the body itself will vibrate, causing the connecting wire between the battery and the starting motor to loosen or fall off.

（3）檢查起動繼電器：使用萬用表測量繼電器線圈和接觸點，接觸不良應及時進行調整或修磨觸點；如線圈燒壞，則更換起動繼電器。

(3) Check the starting relay: use a multimeter to measure the relay coil and contact point. If the contact is poor, adjust or repair the contact in time; If the coil is burnt out, replace the starting relay.

（4）電動馬達：起動馬達本身故障機率較少，但也不能排除。判斷起動馬達的動作情況可在起動發動機的瞬間用手背試探起動馬達的外殼，如起動馬達無動靜且外殼冰冷，說明馬達未動作。或是起動馬達嚴重發燙，有股刺激的焦味，則馬達線圈已燒壞。

(4) Electric motor: the failure probability of the starting motor itself is less, but it cannot be eliminated. To judge the action of the starting motor, use the back of your hand to test the shell of the starting motor at the moment of starting the engine. If the starting motor is not moving and the shell is cold, it means that the motor is not acting. Or if the starting motor is severely hot and has a pungent burning smell, the motor coil has been burnt out.

此外在使用時應及時檢查機油和冷卻水溫度，保證加熱裝置能夠正常運行。了解完以上的原因，就要針對相應的故障原因提出了有效的預防及解決措施，從而有效保障工作的正常生產需求。更多相關內容您可以來我們網站http://www.cxxrdz.com進行咨詢了解了。

In addition, the temperature of engine oil and cooling water shall be checked in time to ensure the normal operation of the heating device. After understanding the above reasons, it is necessary to put forward effective prevention and solution measures for the corresponding fault causes, so as to effectively guarantee the normal production demand of the work.
