Abstract

The invention discloses a level change tendency based oil leak warning method. The level change tendency based oil leak warning method specifically comprises the following steps of, firstly, capturingand recording the current level value of a hydraulic lubricating oil station oil tank at set intervals; secondly, taking the maximum value of the N level values captured in the first step as the theoretical level value of the oil tank; thirdly, comparing the current level value of the hydraulic lubricating oil station oil tank with the theoretical level value, and if the current level value exceeds the theoretical level value by a certain limit, issuing an alarm to prompt maintainers to check. The level change tendency based oil leak warning method can issue an alarm for oil leak in advance,reduce oil loss due to long-term oil leakage and ensure a smooth rolling process.

Description

technical field

[0001] The invention relates to an oil leakage early warning function of a hydraulic lubrication station of a metallurgical steel rolling production line, in particular to an oil leakage early warning method for liquid level change trends. Background technique

[0002] When oil leakage occurs in the hydraulic and lubrication stations, the inspection personnel at night cannot detect the change in the liquid level of the oil tank in time due to the long inspection period, resulting in interruption of rolling when the oil leaks to the trip limit, resulting in unplanned rolling and oil leakage. In order to prevent a large amount of product loss, in order to give early warning of oil leakage, monitor the trend of oil level changes, ensure smooth rolling and prompt prompts for suspicious oil leakage. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an oil leakage early warning method for liquid level cha...

Examples

Embodiment 1

[0014] This embodiment provides a method for early warning of oil leakage with a liquid level change trend, which specifically includes the following steps:

[0015] (1) Grab the liquid level value of the oil tank of the current hydraulic lubricating oil station every 8 minutes, and record it;

[0016] (2) Get the maximum value among the liquid level values ​​captured 25 times in step (1), as the theoretical liquid level value of the fuel tank;

[0017] (3) Compare the liquid level value of the oil tank of the current hydraulic lubricating oil station with the theoretical liquid level value. If the current liquid level value exceeds the theoretical liquid level value by 2%, an alarm will be issued to prompt the maintenance personnel to check.
