Abstract
The invention discloses a kind of liquid level variation tendency oil leak method for early warning, specifically include following steps：(i) the liquid level numerical value of the primary current hydrodynamic lubrication petrol station fuel tank of crawl at regular intervals, and recorded；(ii) the maximum value in the step liquid level numerical value that (i) middle n times capture, the theoretical level value as fuel tank are taken；(iii) the level value of current hydrodynamic lubrication petrol station fuel tank is compared with theoretical level value, if after current level value exceeds one threshold value of theoretical level value, is alarmed, prompting maintenance personnel check；The present invention can give warning in advance oil leak situation, reduce the oil loss that oil product is brought by long-time oil leak, and ensure the smooth of the operation of rolling.
Description
Technical field
The present invention relates to metallurgical steel rolling production-line hydrodynamic lubrication station oil leak warning functions, and in particular to a kind of variation of liquid level becomes
Gesture oil leak method for early warning.
Background technology
When oil leak situation occur in hydraulic pressure, lubrication station, night routing inspection personnel can not have found oil in time because the overhaul period is longer
Case liquid level changes, and causes to generate rolling when oil leak to tripping limit and interrupt, causes to roll unplanned and oil product and largely lose, to carry
Preceding early warning oil leak situation monitors oil level variation tendency, it is ensured that rolling is smoothed out and oil leak doubtful situations prompt in time.
Invention content
The technical problem to be solved by the present invention is to for the above disadvantage of the existing technology, provide a kind of liquid level change
Change trend oil leak method for early warning.
The technical solution that the present invention solves the above technical problem is：A kind of liquid level variation tendency oil leak method for early warning, specifically
Include the following steps：
(i) the liquid level numerical value of the primary current hydrodynamic lubrication petrol station fuel tank of crawl at regular intervals, and recorded；
(ii) the maximum value in the step liquid level numerical value that (i) middle n times capture, the theoretical level value as fuel tank are taken；
(iii) the level value of current hydrodynamic lubrication petrol station fuel tank is compared with theoretical level value, if current level value is beyond reason
It after one threshold value of level value, alarms, prompting maintenance personnel check.
The present invention further limits scheme：
Aforementioned step (i) in, every the liquid level numerical value of the primary current hydrodynamic lubrication petrol station fuel tank of 5-10min crawls.
Aforementioned step (ii) in, N 20-25.
Aforementioned step (iii) in certain value be normal level variation tendency determine, specially 2-3%.
The beneficial effects of the invention are as follows：After use, can give warning in advance the present invention oil leak situation, reduce oil product because of length
The oil loss that time oil leak is brought, and ensure the smooth of the operation of rolling, avoid the rolling generated to limit value by oil leak different
Often interrupt；Also save every year that economic loss about, is also reduced caused by rolling abnormal interrupt caused by oil loss simultaneously
Unplanned loss and roll steel-fastening failure costs.
Specific implementation mode
Embodiment 1
The present embodiment provides a kind of liquid level variation tendency oil leak method for early warning, specifically include following steps：
(i) it every the liquid level numerical value of the primary current hydrodynamic lubrication petrol station fuel tank of 8min crawls, and is recorded；
(ii) take step (i) in 25 times crawl liquid level numerical value in maximum value, the theoretical level value as fuel tank；
(iii) the level value of current hydrodynamic lubrication petrol station fuel tank is compared with theoretical level value, if current level value is beyond reason
It after level value 2%, alarms, prompting maintenance personnel check.
After use, can give warning in advance the present embodiment oil leak situation, reduce the oil that oil product is brought by long-time oil leak
Product are lost, and ensure the smooth of the operation of rolling, avoid the rolling abnormal interrupt generated by oil leak to limit value；It also saves simultaneously
Economic loss about, also reduces unplanned loss and roll card caused by roll abnormal interrupt caused by oil loss every year
Steel failure costs.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
