Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
Embodiment one
A kind of steam boiler failure self- recoverage control method is present embodiments provided, as shown in figure 1, including step：
S11：When detecting steam boiler failure, judge whether an only parametic fault, if so, switching to standby control
Molding formula simultaneously sends yellow light warning；
S12：If a more than parametic fault, shut down and send red audible and visible alarm.
The steam boiler that the present embodiment provides detection, reparation, fault recovery stream according to corresponding to performing different faults reason
The information such as journey, all fault cues, exclusion, holding all highlights information in touch-screen.
Specifically, steam boiler is when detecting failure, if can recover or can enable standby mode failure, if only
One parametic fault, then switch other operational modes immediately and ensure that equipment is not interrupted, be simultaneously emitted by yellow light warning and remind people
To interfere, repairing；Hard stop and red audible and visible alarm is sent when detecting two and above failure at the same time.
In the present embodiment, parameter includes：Venthole thermometric, go out steam pressure detection, furnace body temperature detection and Liquid level.
Specifically, condition needed for boiler normal operation includes venthole thermometric, goes out steam pressure detection, furnace body temperature detection

Temperature, when going out steam pressure detection or abnormal liquid control, the process that is also again started up, it is specially：
First judge whether an only exception, if so, hard stop and send yellow light warning；Releasing pressure automatically drains again
Again water is filled in steam boiler after remaining water to be again started up.Judge whether the parameter of steam boiler in preset times recovers pre-
If in the range of value, if so, continuing to run with.Otherwise, yellow light warning is sent.
If more than abnormal parameters, hard stop simultaneously sends yellow light warning, then releasing pressure automatically drains steam boiler
Again water is filled after interior remaining water and is again started up.Judge whether the parameter of steam boiler in preset times recovers preset value model
In enclosing, if so, continuing to run with；Otherwise, shut down and send red audible and visible alarm.
The method that the present embodiment provides can automatically terminate fault recovery production in unmanned maintenance, ensure that the stabilization of production
Property and security, lifted fault recovery efficiency while effectively prevent for some reason barrier caused by heavy losses.
