Then remaining water in stove fills water and is again started up, continued to run with if fault recovery again, if failure is still after three times
Spare liquid level detection system restarting is switched to, is continued to run with if failure full recovery, the hard stop if failure remains unchanged
And send out red audible and visible alarm.
Specifically,
When first detection module 21 detects the abnormal parameters of steam boiler, first judge whether an only exception, if
It is that hard stop simultaneously sends out yellow light warning；First starting module, 22 releasing pressure automatically is drained in steam boiler after remaining water
Again water is filled to be again started up.First judgment module 23 judges whether the parameter of steam boiler in preset times restores preset value model
In enclosing, if so, continuing to run with.Otherwise, yellow light warning is sent out.
If the second detection module 25 detects more than abnormal parameters, hard stop simultaneously sends out yellow light warning, the
Two starting modules, 26 releasing pressure automatically drains to be filled water and is again started up again after remaining water in steam boiler.Second judgment module
27 judge whether the parameter of steam boiler in preset times is restored in values, if so, continuing to run with；Otherwise, it shuts down simultaneously
Send out red audible and visible alarm.
System provided in this embodiment can automatically terminate fault recovery production in unmanned maintenance, ensure that the stabilization of production
Property and safety, promoted fault recovery efficiency while effectively prevent the heavy losses caused by failure.
