我厂两台杭州产B1.5-24/3汽轮发电机组经5年的运行,润滑油压一直偏低。原设计润滑油压为5.88×10~4～10.79×10~4Pa,实际上的压力只达3.9×10~4～6.9×10~4Pa。这种情况不仅对各轴瓦的安全运行有很大危险,而且对齿轮联轴器的润滑也有不良影响。5年来我厂共更换了两套齿轮联轴器。造成磨损的原因有可能是喷油管离齿轮联轴器太远,当油压低时润滑油喷不到齿面上,从而引起润滑不良所致。5年来我们对润滑油压偏低的问题进行了多次调整、试验。我们首先对注油器喷嘴到扩散管的喷射距离进行了调整,但加大或减少这个
Two Hangzhou factory production B1.5-24 / 3 turbine generator sets after 5 years of operation, lubricating oil pressure has been low. The original design of lubricating oil pressure of 5.88 × 10 ~ 4 ~ 10.79 × 10 ~ 4Pa, the actual pressure of only 3.9 × 10 ~ 4 ~ 6.9 × 10 ~ 4Pa. This situation is not only a great danger to the safe operation of the bearing pads, but also has an adverse effect on the lubrication of the gear couplings. 5 years I plant a total of two sets of gear couplings. Causes of wear may be too far from the gear coupling fuel injection pipe, when the oil pressure is low, the oil can not spray to the tooth surface, resulting in poor lubrication. In the past 5 years, we have made many adjustments and tests on the problem of low lubricating oil pressure. We first adjust the jetting distance from the injector nozzle to the diffuser tube, but increase or decrease this
