When does the auxiliary oil pump stop operating? And how should it be started? This post was last edited by shanxg on 2009-4-7 13:29
P-3302 belongs to high-speed centrifugal pumps. There are separate oil pipelines, which include an oil cooler, an oil filter, a main oil pump (located within the pump body), and an auxiliary oil pump. Its main function is to circulate the lubricating oil within the gearbox. At startup, the auxiliary oil pump is started first; once the temperature and pressure of the lubricating oil meet the requirements for operating the pump, it can be stopped. Then the pump can be started (simultaneously, the main oil pump also begins to operate). Oil pipeline: After coming out of the outlet of the auxiliary oil pump, the lubricating oil enters the oil cooler, then the oil filter, followed by the gearbox, and finally reaches the inlet of the auxiliary oil pump
When the temperature and pressure of the lubricating oil meet the requirements for starting the pump, it can be stopped. What are the specific temperature and pressure? Thank you!
1. Before the main unit starts up, the auxiliary oil pump is activated and put under automatic control; 60 seconds after the main motor (main oil pump) starts, the auxiliary oil pump shuts down； 2. When the oil pressure is below 2.8 bar during operation, an alarm is triggered; when it drops below 1.5 bar, the auxiliary oil pump starts automatically. 3. When the main motor stops, the auxiliary oil pump starts automatically and shuts down after 60 seconds of operation. The above time and pressure point meters are adjustable
Hehehe, just learned it. . . I give up:P
