焦化發(fā)電機(jī)組怠速運(yùn)轉(zhuǎn)時(shí)，轉(zhuǎn)速忽快忽慢不穩(wěn)定。在檢查點(diǎn)火系統(tǒng)沒(méi)有故障的情況下，故障可能發(fā)生在燃料供給系統(tǒng)、怠速步進(jìn)電機(jī)失控，此時(shí)應(yīng)檢查焦化裝置及電機(jī)。
During the idling operation of the coking generator set, the rotating speed is unstable. If there is no fault in the ignition system, the fault may occur in the fuel supply system and the idle stepper motor out of control. At this time, check the coking device and motor.
一：
I:
1)進(jìn)氣道是否有漏氣現(xiàn)象。
1) Check whether there is air leakage in the air inlet.
2)混合器空燃比調(diào)整是否合適。
2) Whether the mixer air-fuel ratio is adjusted properly.
3)混合器閥芯有否卡滯現(xiàn)象。
3) Check whether the mixer valve core is stuck.
4)混合器膜片是否破損漏氣，造成有高速無(wú)低速現(xiàn)象。
4) Check whether the mixer diaphragm is damaged and air leaks, causing high-speed and low-speed phenomena.
