压缩机的运动机构包括曲轴、连杆、十字头和曲轴轴承等部件。由主轴传动的油泵(或由单独的电动油泵)组成供油系统供给润滑油。润滑油经润滑点后返回油池,再经油泵打回润滑点,这样就形成油的循环系统。往往在压缩机实际运行中,人们很少注意较远点的润滑情况,因而很容易造成较远点润滑状况不良,使磨损加剧,从而发生距油泵较远的十字头、飞轮端曲轴轴承研磨烧坏的现象。以我厂35y- 75/150型的氢气压缩机,烧坏飞轮端曲轴轴承(压力润滑)为例。说明重视较远点润滑的重要性和必要性。但造成较远点烧瓦、抱轴的因素有:长期供油不足,是泵前吸油管接头及泵的各部结合面由于螺帽的松动而不严密,泵开动后产生漏油现象;油管堵塞,油内的污物沉积在管内,使油流受阻;吸油管对焊时焊口焊细,或管子变形;有的油泵位置的油池较低,开车前没有
Compressor movement agencies, including crankshaft, connecting rod, crosshead and crankshaft bearings and other components. The main shaft-driven pump (or by a separate electric pump) to form the oil supply system for lubricating oil. Lubricating oil after the return to the oil pool, and then hit the pump back to the lubrication point, so that the formation of oil circulation system. Often in the actual operation of the compressor, people pay little attention to the lubrication of the distant point, which is likely to cause the lubrication point far point bad condition, so that wear increased, resulting from the pump away crosshead, flywheel crankshaft bearing grinding burn Bad phenomenon. Take our factory 35y- 75/150 type hydrogen compressor, burn out flywheel end crankshaft bearing (pressure lubrication) as an example. Explain the importance and necessity of attaching more importance to the lubrication of distant spots. However, the factors that cause the burning of the tile and the shaft of the axle far are as follows: the long-term oil supply is insufficient; the joint of the oil suction pipe joint and each part of the pump before the pump is not tight due to the loosening of the nut; oil leakage occurs after the pump starts; , The dirt in the oil deposited in the tube, so that the flow of oil blocked; suction pipe butt weld weld fine, or tube deformation; some oil pump location lower oil pool, before driving
