The starting ignition system of combustion machine is substance system, once break down, cannot start unit, and because it is arranged on the outer wall of combustion machine light oil gun body, is inserted into combustion chamber together with light oil rifle, long-term in more than 1000 ℃ high-temperature work environments.Be so limited, do not possess the condition of online replacing parts.
According to the accident analysis in loss of ignition process, the porcelain bushing shell 6 of ignitor outside can produce " burst porcelain " after work certain hour, cause and metallic support shelf depreciation, make transferring energy cause loss between ignitor 2 and metallic support, ignition process is because of energy shortage, and cause combustion machine start in loss of ignition.
In burner maintenance, need to winch to inspection platform, at this moment original fixing test loop does not form effective connection, and test again after returning dress, cannot carry out again fault screens out, remedial efforts after loss of ignition, not only propane and the light oil of waste igniting use, and can be because the multiple labour on time after maintenance has influence on normal production work.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of burner off-line state down-firing electrode inspector, this device is for needing to winch to inspection platform in the maintenance of combustion in situ device, cannot carry out in time ignition installation inspection, ignition failure screens out and designs, quasi-complement the generated energy loss that causes of original loss of ignition and propane and the waste of light oil material of the use of lighting a fire accordingly, thereby improved combustion machine ignition success rate, guarantee unit generation effect.
The utility model is achieved in that a kind of burner off-line state down-firing electrode inspector, comprise the pressure unit, rectification unit and the igniting generating unit that connect in turn, the input of described pressure unit and power input plug are connected, the output of described igniting generating unit is communicated with ignition plug by cable, the metal probe of ignitor is inserted into gets angry in plug, is also provided with signal and cuts throwing switch in this device.
Described signal is cut and is thrown switch and be arranged on the output of rectification unit.
Described pressure unit and igniting generating unit ground connection.
Described cable ground connection.
The utility model burner off-line state down-firing electrode inspector off-line detects ignitor, the state of equipment has been had to better control, for needing to winch to inspection platform in the maintenance of combustion in situ device, cannot carry out in time ignition installation inspection, ignition failure screens out and designs.Quasi-complement the generated energy loss that causes of original loss of ignition and propane and the waste of light oil material of the use of lighting a fire accordingly; When maintenance, by detecting timely eliminating deterioration state, assurance equipment is reliable, thereby improved combustion machine ignition success rate, guarantees unit generation effect.
