在沼氣發(fā)電機組中，油的指示起著(zhù)關(guān)鍵作用。特別是在夏季，油溫水平不足會(huì )對發(fā)電機組產(chǎn)生嚴重的不利影響。那么沼氣發(fā)電機組提示啟動(dòng)高度不足怎么辦呢？下面來(lái)看看吧。

In the biogas generator set, the indication of oil plays a key role. Especially in summer, the insufficient oil temperature level will have a serious adverse impact on the generator set. So what if the biogas generator unit prompts that the starting height is insufficient? Let's have a look.

該發(fā)電機組油位高度不足一般是曲柄連桿軸頸與連桿間隙過(guò)大造成的。這時(shí)，潤滑油路中的油從這里漏入油底殼，然后少到油量指示閥，所以油量指示閥升得不夠；軸承座孔與曲軸間隙過(guò)大。機器的油量指示閥需要升起。油泵送出的油進(jìn)入軸承座上的圓形油槽，再通過(guò)軸承座上的油孔和油管進(jìn)入油位計。

The insufficient oil level of the generator set is generally caused by the excessive clearance between the crank and connecting rod journal and connecting rod. At this time, the oil in the lubricating oil circuit leaks into the oil pan from here, and then the oil quantity indicator valve is less than that, so the oil quantity indicator valve is not raised enough; The clearance between bearing seat hole and crankshaft is too large. The oil quantity indicating valve of the machine needs to be raised. The oil sent by the oil pump enters the circular oil groove on the bearing seat, and then enters the oil level gauge through the oil hole and oil pipe on the bearing seat.

當配合間隙過(guò)大時(shí)，大部分油從這里泄漏到油底殼中，使油量指示閥得到的油少，因此油量指示閥升得不夠高。慢慢加速。這種故障有以下三種表現：

When the fitting clearance is too large, most of the oil leaks into the oil pan from here, so that the oil quantity indicating valve gets less oil, so the oil quantity indicating valve rises not high enough. Accelerate slowly. This fault has the following three manifestations:

(1)松開(kāi)調速齒輪中固定調速支架的螺釘，使調速滑板向外移動(dòng)，通過(guò)調速將高壓油泵油量調節架移至減油位置杠桿，導致柴油機加速緩慢，嚴重的甚至使柴油機無(wú)法啟動(dòng)；

(1) Loosen the screw fixing the speed regulating bracket in the speed regulating gear to make the speed regulating sliding plate move outward, and move the high-pressure oil pump oil volume regulating bracket to the oil reduction lever through speed regulation, resulting in slow acceleration of the diesel engine, and even making the diesel engine unable to start seriously;

(2)沼氣發(fā)電機組調速齒輪襯套在調速齒輪上的配合松緊度不夠。這時(shí)襯套會(huì )出來(lái)，調速桿會(huì )減少高壓油泵的供油量，導致柴油機加速緩慢。

(2) The matching tightness of the speed regulating gear bushing of the biogas generator set on the speed regulating gear is not enough. At this time, the bushing will come out, and the speed regulating lever will reduce the oil supply of the high-pressure oil pump, causing the diesel engine to accelerate slowly.

(3)調速滑板卡在調速軸上。此時(shí)，調速桿不靈活地移動(dòng)高壓油泵油量調節齒輪桿，使柴油機緩慢加速。當滑板在很外端時(shí)，調速鋼球卡在調速滑板和調速架之間，高壓油泵油量調節齒輪桿處于停油位置，柴油機根本無(wú)法啟動(dòng)。

(3) The speed regulating sliding plate is stuck on the speed regulating shaft. At this time, the speed regulating lever does not flexibly move the oil volume regulating gear lever of the high-pressure oil pump, so that the diesel engine accelerates slowly. When the sliding plate is at the outer end, the speed regulating steel ball is stuck between the speed regulating sliding plate and the speed regulating frame, and the oil volume regulating gear rod of the high-pressure oil pump is in the oil stop position, and the diesel engine cannot be started at all.
