好色先生在线观看在低速和中速的範圍內出現周期較長且較有規律的時快時慢現象，這是調速反應過分滯後於實際轉速變化的結果。其原因主要有以下幾種。

The generator set exhibits a longer and more regular phenomenon of fast and slow speed in the low and medium speed ranges, which is the result of the speed control response lagging too far behind the actual speed change. There are several main reasons for this.

調速器內部杠杆因連接銷孔磨損而鬆曠

The internal lever of the governor is loose due to wear and tear on the connecting pin hole

這種情況下，使增減供油量的雙向調速運動產生了過多的變向滯後。發動機工作時，調速反應是必然滯後於實際轉速變化的，但滯後量不能太大，否則就會產生較大的調節振幅。調節振幅過大，即當轉速已經由於供油量的增減而導致轉速升降時仍將繼續增減燃油，直到轉速超過調速器調節範圍較大後，其強烈的反饋信號才通過調速器實現反向調節的反應，結果使調速反應超出了預定的範圍，造成了轉速在其附近反複有規律升降的時快時慢現象。

In this case, there is too much directional lag in the bidirectional speed control movement of increasing or decreasing fuel supply. When the engine is working, the speed control response will inevitably lag behind the actual speed change, but the lag amount cannot be too large, otherwise it will produce a large adjustment amplitude. The adjustment amplitude is too large, that is, when the speed has already increased or decreased due to the increase or decrease of fuel supply, the fuel will continue to increase or decrease until the speed exceeds the large adjustment range of the speed controller. The strong feedback signal is then reflected through the speed controller to achieve reverse adjustment, resulting in the speed regulation response exceeding the predetermined range, causing the speed to repeatedly rise and fall in a regular pattern near it, which is fast and slow.

供油齒杆不夠靈活

The fuel supply gear rod is not flexible enough

噴油泵的供油齒杆須保持靈活，以保證調速反應的靈敏性。用靈敏的彈簧秤對齒杆進行拉動阻力測試，對應缸噴油泵的拉動阻力應分別不大於規定值。由於生鏽、柱塞偶件緊固後變形、柱塞彈簧折斷後齒圈與齒杆齧合處碾傷、齒杆端部軸套嚴重磨損、撥叉式油量調節機構的撥叉緊固角度不正確，噴油泵調速器的推力斜盤和飛球座的安裝或配合不良等原因，都會影響供油齒杆的靈活性。當這種影響靈活性的阻力還未達到使供油齒杆不能移動的程度時，就會出現時快時慢現象（若供油齒杆不能移動，出現故障現象將視齒杆停留位置不同而有所區別；例如，柴油發電機不能啟動、不能熄火、轉速不受控製、飛車等）

The fuel supply gear of the fuel injection pump must remain flexible to ensure the sensitivity of the speed control response. Use a sensitive spring scale to test the pulling resistance of the gear rod, and the corresponding cylinder fuel injection pump's pulling resistance should not exceed the specified value. Due to rusting, deformation of the plunger coupling after tightening, grinding of the meshing area between the gear ring and the gear rod after the plunger spring is broken, severe wear of the shaft sleeve at the end of the gear rod, incorrect fastening angle of the shift fork of the oil quantity adjustment mechanism, and poor installation or fit of the thrust swash plate and flying ball seat of the fuel injection pump governor, the flexibility of the fuel supply gear rod can be affected. When the resistance that affects flexibility has not yet reached the point where the fuel supply gear rod cannot move, there will be a phenomenon of fast and slow (if the fuel supply gear rod cannot move, the fault phenomenon will vary depending on the position of the gear rod; for example, diesel generators cannot start, cannot stop, speed is not controlled, and speeding)

穩速彈簧調整不當

Improper adjustment of the speed stabilizing spring

這與怠速不穩定時穩速彈簧調整不當相似，是因為穩速彈簧與供油齒杆不能共同靈活的起作用。

This is similar to improper adjustment of the stability spring when idling is unstable, because the stability spring and the fuel supply gear cannot work together flexibly.
