In the gas generating unit, the indication of oil is very important. Especially in summer, the lack of oil temperature level will have serious adverse effects on the automatic diesel generating set. The elevation of the oil level of the gas generator is generally due to the excessive gap gap between the crank shaft neck and the connecting rod. At this time, the oil in the lubricating oil line is leaking into the oil pan from this point, and then goes to the oil indicating valve, so it causes the height of the oil indicating valve is insufficient.
The gap between the bearing seat hole and the crankshaft is too large. The machine oil indicator valve to rise, is sent by the oil pump oil into the circular groove bearing seat, the bearing seat of the oil hole and the oil pipe into the engine oil indicating Yan, when the clearance is too large, most of the oil from leaking into the oil pan, the oil valve to get instructions the oil is less, therefore the oil indicator valve rises high enough.
Speed up slowly. There are three manifestations of this fault as follows:
(1) the loosening of the screws of the fixed speed governing bracket in the speed regulating gear causes the speed governing sliding disc to move outwards. By adjusting the lever of the high speed oil pump, the speed governing sliding disc moves outwards, so that the rack moves to the oil reducing position, causing the diesel engine to accelerate slowly and seriously and even make the diesel engine fail to start.
(2) the speed regulating gear bushing of gas generator set is not enough in speed control gear, so the bushing will move out of it, and the fuel supply of high pressure oil pump will be reduced by speed control lever, which will cause slow acceleration of diesel engine.
(3) the speed control slide plate is stuck in the speed control shaft, and the speed control lever moves the oil quantity of the high pressure oil pump to adjust the tooth rod inflexibly, so that the diesel engine is accelerated slowly. When the sliding disc is at the most outer end, the speed regulating steel ball is stuck between the speed regulating sliding disc and the speed regulating frame, and the oil content of the high pressure pump is adjusted, and the gear bar is at the stop position, and the gas generating set can't start at all.
