Abstract
The invention discloses a high-low pressure lubrication system for a high-horsepower plunger pump, including a high-pressure oil line and a low-pressure oil line, the high-pressure oil line is used for lubricating the connecting rod bearing bushes and the crosshead bearing bushes in the plunger pump, the low-pressure oil line is used for lubricating the crankshaft bearings, the crosshead sliding rails, the reduction gearbox bearing, and the reduction gearbox gear pair in the plunger pump. The beneficial effects are as follows: oil is fed in two passages: a high-pressure oil line and a low-pressure oil line, the high-pressure oil line is used for lubricating the connecting rod bearing bushes and the crosshead bearing bushes, and the low-pressure oil line is used for lubricating the crankshaft bearings, the crosshead sliding rails, the reduction gearbox bearing, and the reduction gearbox gear pair; two oil pumps are employed to supply oil so that the oil supply of each oil line could be better guaranteed, thus better distributing the lubricating oil, and avoiding problems of uneven distribution of lubricating oil caused by excessive lubrication branches and insufficient amount of lub…
