【Q&A Question 057】On June 16, 2016, the lubrication oil pressure experienced significant fluctuations during the cranking of the diesel hydrogenation unit pump; analyze the possible causes. The answer key will be available after responding; scoring is based on answering the key points. When turning the pump, pay attention to the direction of rotation. When turning it in its normal direction, the lubricating oil pressure will decrease, while when turning it in the reverse direction, the lubricating oil pressure will increase.
Low lubricant temperature and high viscosity； Low and uneven rotation speed, with high back-pressure
The crosshead moves back and forth, blocking the oil outlet
Is this situation possible too? Clogged lubrication chamber?
