哈尔滨炼油厂重整加氢联合装置予加氢压缩机有两台油泵，其一为主油泵，另一为辅助油泵。正常工作时，主油泵为手动状态，辅助油泵为自动状态。在总管润滑油压力低于设定油压下限值时辅助油泵自动起动，补充油压，防止压缩机主机因润滑油压低而停机。 一次，主油泵所在段电源进 Harbin Refinery Hydrogenation unit reformer to hydrogenation compressor has two pumps, one of the main oil pump, and the other for the auxiliary pump. Normal work, the main pump for the manual state, auxiliary pump for the automatic state. When the manifold oil pressure is lower than the set pressure limit, the auxiliary pump will start automatically and replenish the oil pressure to prevent the compressor main engine from stopping due to the low lubricating oil pressure. Once, the main section where the main pump into the power
