At this time, it is necessary to stop the main lubrication pump 2 and start using the auxiliary lubrication pump 3 for lubrication. When the auxiliary lubrication pump 3 is working, the lubricating oil will first enter the oil pipe housing 52 through the hose. At this time, the water circulation pipe 53 is immersed in the lubricating oil. The water inside the water circulation pipe 53 will circulate through the water inlet 56 and the water outlet 57 to reduce the temperature of the lubricating oil. The cooled lubricating oil will then be transported to the auxiliary distributor 6 through the oil outlet 54. The auxiliary distributor 6 will then distribute the cooled lubricating oil to the lubrication points with increased temperature to cool the lubrication points, effectively reduce the temperature at the lubrication points, and extend the service life of the machinery.

The main lubrication pump 2 is used for normal mechanical lubrication, and the auxiliary lubrication pump 3 is used under specific conditions such as mechanical friction and high temperature. Alternating use can make the operation of the pump group more stable, reduce fluctuations caused by continuous operation, and improve the stability of the system. At the same time, when the main lubrication pump 2 stops working due to a fault, the auxiliary lubrication pump 3 can start immediately and take over the work, thereby avoiding equipment damage and shutdown risks caused by lubrication interruption, and significantly improving the stability and reliability of the system.
