        發(fā)電機組運轉時(shí)快時(shí)慢,是不是出現了故障?

        調速器內部杠桿因連接銷(xiāo)孔磨損而松曠

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

        這種情況下,使增減供油量的雙向調速運動(dòng)產(chǎn)生了過(guò)多的變向滯后。發(fā)動(dòng)機工作時(shí),調速反應是必然滯后于實(shí)際轉速變化的,但滯后量不能太大,否則就會(huì )產(chǎn)生較大的調節振幅。調節振幅過(guò)大,即當轉速已經(jīng)由于供油量的增減而導致轉速升降時(shí)仍將繼續增減燃油,直到轉速超過(guò)調速器調節范圍較大后,其強烈的反饋信號才通過(guò)調速器實(shí)現反向調節的反應,結果使調速反應超出了預定的范圍,造成了轉速在其附近反復有規律升降的時(shí)快時(shí)慢現象。

        In this case, the bidirectional speed regulation movement that increases or decreases the fuel supply has caused excessive directional lag. When the engine is working, the speed response is inevitably lagging behind the actual speed change, but the lag should not be too large, otherwise a large adjustment amplitude will occur. The amplitude of the adjustment 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 adjustment range of the governor. The strong feedback signal will only be reflected in the reverse adjustment through the governor, resulting in the speed response exceeding the predetermined range, causing the speed to repeatedly rise and fall in a regular pattern near it, sometimes fast and sometimes slow.

        供油齒桿不夠靈活

        The fuel supply gear rod is not flexible enough

        噴油泵的供油齒桿須保持靈活,以保證調速反應的靈敏性。用靈敏的彈簧秤對齒桿進(jìn)行拉動(dòng)阻力測試,對應缸噴油泵的拉動(dòng)阻力應分別不大于規定值。由于生銹、柱塞偶件緊固后變形、柱塞彈簧折斷后齒圈與齒桿嚙合處碾傷、齒桿端部軸套嚴重磨損、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(pán)和飛球座的安裝或配合不良等原因,都會(huì )影響供油齒桿的靈活性。當這種影響靈活性的阻力還未達到使供油齒桿不能移動(dòng)的程度時(shí),就會(huì )出現時(shí)快時(shí)慢現象(若供油齒桿不能移動(dòng),出現故障現象將視齒桿停留位置不同而有所區別;例如,柴油發(fā)電機不能啟動(dòng)、不能熄火、轉速不受控制、飛車(chē)等)

        The fuel supply rod 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 pulling resistance of the corresponding cylinder fuel injection pump should not exceed the specified value. Due to rusting, deformation of plunger components after fastening, crushing at the meshing point between the gear ring and the gear rod after the plunger spring is broken, severe wear on the shaft sleeve at the end of the gear rod, incorrect tightening angle of the shift fork of the oil quantity adjustment mechanism, and poor installation or coordination of the thrust inclined 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 level that prevents the fuel supply rod from moving, a phenomenon of sometimes fast and sometimes slow will occur (if the fuel supply rod cannot move, the fault phenomenon will vary depending on the position of the rod; for example, diesel generators cannot start, cannot stop, the speed is not controlled, and the speed is flying, etc.)

        穩速彈簧調整不當

        Improper adjustment of the stabilizing spring

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

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