焦化發(fā)電機(jī)組和柴油發(fā)電機(jī)組等一樣都是作為一種電源設(shè)備，機(jī)組質(zhì)量良好，性能穩(wěn)定。各因素的作用機(jī)組難免會出現(xiàn)故障。那么，焦化發(fā)電機(jī)組功率不足故障什么原因，怎么辦？

Coking generator set and diesel generator set are the same as a kind of power equipment, with good quality and stable performance. Due to various factors, the unit will inevitably fail. Then, what is the reason for the power shortage fault of coking generator set and how to do it?

焦化發(fā)電機(jī)組進(jìn)、排系統(tǒng)故障：

Coking generator set inlet and exhaust system failure:

1、空氣濾清器阻塞；解決方法：清洗空氣濾清器芯子或清理紙質(zhì)濾芯上的灰塵，必要時(shí)應(yīng)更換；

1. The air filter is blocked; Solution: clean the air filter core or dust on the paper filter element, and replace it if necessary;

2、排氣管阻塞或接管過長、轉(zhuǎn)彎半徑太小，彎頭太多；解決方法：清理排氣管內(nèi)積碳：重裝排氣接管，彎頭不能多于三個(gè)，并有足的排氣截面；

2. The exhaust pipe is blocked or the connecting pipe is too long, the turning radius is too small, and there are too many elbows; Solution: clean up the carbon deposit in the exhaust pipe: reinstall the exhaust pipe, with no more than three elbows and sufficient exhaust section;

發(fā)電機(jī)組發(fā)動(dòng)機(jī)過熱，環(huán)境溫度過高，機(jī)油和冷卻水溫度很高，排溫也大大增高；解決方法：檢修冷卻器和散熱器，清理水垢，檢查有關(guān)管路是否管徑過小，如環(huán)境溫度過高應(yīng)改善通風(fēng)，臨時(shí)加強(qiáng)冷卻措施。

The generator set engine is overheated, the ambient temperature is too high, the oil and cooling water temperature is very high, and the exhaust temperature is also greatly increased; Solution: overhaul the cooler and radiator, clean the scale, check whether the pipe diameter is too small. If the ambient temperature is too high, improve the ventilation and temporarily strengthen the cooling measures.

發(fā)電機(jī)組連桿軸瓦與曲軸連桿軸頸表面咬毛：有不正常聲音，并有機(jī)油壓力下降等現(xiàn)象；解決方法：拆卸發(fā)動(dòng)機(jī)側(cè)蓋板，檢查連桿大頭的側(cè)向間隙，看連桿大頭是否能前后移動(dòng)，如不能移動(dòng)則表示咬毛，應(yīng)修磨軸頸和更換連桿軸瓦；

The surface of the connecting rod bearing bush of the generator set and the connecting rod journal of the crankshaft is scratched: there is abnormal sound and oil pressure drops; Solution: remove the side cover plate of the engine, check the lateral clearance of the connecting rod big end, and see whether the connecting rod big end can move back and forth. If it cannot move, it means galling. Repair the journal and replace the connecting rod bearing bush;

焦化發(fā)電機(jī)組燃?xì)庀到y(tǒng)故障

Gas system failure of coking generator set

1、氣壓低，供氣量不足；解決方法：提高氣壓

1. Low air pressure and insufficient air supply; Solution: increase the air pressure

2、燃?xì)赓|(zhì)量差；解決方法：增大燃?xì)膺M(jìn)氣量

2. Poor gas quality; Solution: increase the gas intake

3、燃?xì)獾蓝氯?；解決方法:清理；

3. The gas passage is blocked; Solution: clean up;

4、混合器膜片有裂縫；解決方法：更換膜片；

4. Cracks in the mixer diaphragm; Solution: replace the diaphragm;

焦化發(fā)電機(jī)組氣缸蓋組件故障：此時(shí)不但功率不足，性能下降，而且有漏氣、進(jìn)氣管冒黑煙，有不正常的敲擊聲等現(xiàn)象。

Failure of cylinder head assembly of coking generator set: at this time, not only the power is insufficient, the performance is degraded, but also there are air leakage, black smoke from the intake pipe, abnormal knocking sound and other phenomena.

1、氣管蓋與機(jī)體結(jié)合面漏氣，變速時(shí)有一股氣流從襯墊處沖出：氣缸蓋大螺柱松動(dòng)或襯墊損壞；解決方法：按規(guī)定扭矩?cái)Q緊大螺柱螺母或更換氣缸蓋襯墊，需要的話修刮接合面。

1. There is air leakage on the joint surface between the gas tube cover and the engine body, and a stream of air rushes out of the gasket during speed change: the large studs of the cylinder head are loose or the gasket is damaged; Solution: tighten the large stud nut according to the specified torque or replace the cylinder head gasket, and scrape the joint surface if necessary.

2、進(jìn)、排氣門漏氣；解決方法：拆檢進(jìn)、排氣門，修磨氣門與氣門座配合面；

2. Air leakage of inlet and exhaust valves; Solution: disassemble and inspect the inlet and exhaust valves, and grind the mating surface between the valve and the valve seat;

3、氣門彈簧損壞；解決方法：更換已損壞的彈簧；

3. Valve spring is damaged; Solution: replace the damaged spring;

4、氣門間隙不正確；解決方法：重校氣門間隙至規(guī)定值；

4. Incorrect valve clearance; Solution: recalibrate the valve clearance to the specified value;

5、活塞環(huán)卡住，氣門桿咬住引起氣缸壓縮壓力不足；解決方法：拆下檢修、清理并更換已損壞的零件；

5. The piston ring is stuck, and the valve rod bites, causing insufficient compression pressure of the cylinder; Solution: dismantle, repair, clean and replace the damaged parts;

焦化發(fā)電機(jī)組進(jìn)、排氣相位變動(dòng)；各檔轉(zhuǎn)速下性能變差；解決方法：進(jìn)行配氣相位和氣門間隙檢查。

Phase change of inlet and exhaust of coking generator unit; The performance becomes worse at each speed; Solution: check the valve timing and valve clearance.
