Embodiment Construction

[0050] Usually, the main engine lubricating oil system of a ship includes the following equipment: lubricating oil storage cabinet, dirty oil storage cabinet, oil residue tank, filter screen, crude oil filter, duplex filter, manual lubricating oil pump, machine belt lubricating oil circulation pump, lubricating oil Pre-supply and delivery pumps, dirty oil pumps, manual dirty oil pumps, lubricating oil coolers, thermostats, valves (pressure regulating valves, check valves, etc.), piping systems (oil main pipe branch pipes, oil return pipes, oil suction pipes, oil overflow pipes, etc.)

[0051] General ship lubricating oil system risk warning schematic diagram figure 1 Shown: The oil pump sucks the lubricating oil from the belt oil pan through the pipeline, through the temperature regulator and cooler, or through the bypass pipeline to the oil filter, and then to the oil main pipe on the engine. When the engine starts, the bearing lubricating oil is provided by the pre-feed pump...

Abstract

The invention relates to a ship lubricating oil system risk early warning method; when the ship lubricating oil system is discovered to have abnormal situations; the risk early warning is processed according to the following steps that step one, the malfunction mode is determined whether the malfunction mode is the lower engine oil pressure malfunction mode, the over high temperature engine oil malfunction mode, the risen liquid level machine belt oil sump malfunction mode or excessive and rapid engine oil consumption malfunction mode according to the device information acquired in real-time through the sensors installed in the survey points of the ship lubricating oil system, and the operation and malfunction information of the device acquired through the manual examination; step two, the risk early warning flow is determined according to the malfunction mode type; the risk early warning is executed according to the corresponding diagnosis flow. The ship lubricating oil system risk early warning method can provide reasonable evidence for the daily maintenance and repairing for the ship lubricating oil system after the risk early warning method is applied.

Description

technical field [0001] The invention belongs to the field of equipment risk early warning, and relates to a risk early warning method for ship sliding equipment. Background technique [0002] During the operation of marine diesel engines, in order to reduce the mutual friction between the moving surfaces, a lubricating oil system is needed to ensure that the moving surfaces will not be severely damaged and scratched. more stringent requirements. Therefore, while strengthening the management of ship turbine equipment, it is particularly important to carry out real-time status diagnosis of the main equipment failures of the ship's lubricating oil system, and to do targeted repair and maintenance according to the diagnosis results. Strengthening the risk warning technology for the ship's lubricating oil system can not only ensure its safety, but also have important significance for reducing the maintenance cost of the ship. Due to the many indicators involved in the risk warn...
