Embodiment
Below in conjunction with drawings and Examples, the utility model is described.
Referring to Fig. 1 and Fig. 2.Whole sprinkle density measurement mechanism is by spraying platform and composition of the control system.Spraying platform main body rack is cuboid, and its physical dimension is about 1800mm length * 1600mm, and wide * 2500mm is high.Tank 1 is installed in bottom, and heating surface bank 11 is installed at middle part, and nozzle positioning system is installed on top, and nozzle positioning system is mainly comprised of spray pipeline 9, nozzle 10, nozzle slideway 6, horizontal direction slideway 4 and vertical direction slideway 5; Bottom tank 1 can be pulled out below heating surface bank 11; In nozzle positioning system, there are two nozzle slideways, 2 nozzles are installed on each nozzle slideway, nozzle slideway 4 is connected with vertical direction slideway 5 with horizontal direction slideway 4, and what make that nozzle slideway 4 can be whole moves up and down, and each nozzle can move arbitrarily at three dimensions like this; The bottom of nozzle 10 can regulate to the distance of heating surface bank 11 the superiors' heat-transfer pipes in 200mm～600mm.Feeder pump 2 is installed in tank 1, for water being extracted to Zhi Ge road, states in spray pipeline 9, can Quick Acquisition to liquid level signal, be quick on the draw.Multi-electrode level switch 15 comprises three electrodes, a public electrode 15-2, and its base material is thin titanium rod, outer painting ruthenium; A low level electrode 15-1 and a high level electrode 15-3, its base material is thin copper bar, overcoat low-temperature shrink flame retardant type sleeve pipe, small cylindrical graphite is equipped with as electrode tips in top, in the bottom of liquid trap 3, discharge solenoid valve 16 is set.
