Specific embodiment
A kind of many shower nozzles of spray rod type electrostatic spray specific charge measuring equipment, comprise L-type support 1, vertical sliding moving platform 2, horizontal sliding table 3, droplet gathering-device 5, droplet weighing device 4 and droplet electric quantity measuring device 6, wherein droplet gathering-device is Faraday cylinder, droplet weighing device is precision balance, and droplet electric quantity measuring device is precision ammeter.In addition, rule 11 is installed before L-type support 1 backboard, after open two grooves 14; Parallel four-bar elevating mechanism 7 upper and lower surfaces are arranged on L-type support 1 in the middle of bottom surface with bolt respectively and vertical sliding moving platform 2 centre below; On horizontal sliding table 3, at the two ends of two guide-track grooves 17, respectively open two threaded holes 20, load onto altogether four bolts 8, bolt 8 is stained with rubber blanket 12 below; Wire of droplet gathering-device 5 and droplet electric quantity measuring device 6 use is connected; The below of droplet gathering-device 5 has a water delivering orifice 9.Vertical sliding moving platform is arranged on L-type support 1 with two M20 bolts 10.
When concrete enforcement is of the present invention, the height of the shower nozzle 18 of surveying as required, rotation parallel four-bar elevating mechanism 7 handles, by feed screw nut, drive four bars to move simultaneously, change angle between symmetrical upper and lower two bars, the position that regulates vertical sliding moving platform 2 moves up and down it on L-type support 1 along guide rail.Adjust to after the height that is applicable to measuring, on rule 11, read and record reading.Screw two M20 bolts, vertical sliding moving platform 2 is fixed on support 1, parallel four-bar elevating mechanism 7 can be removed.The horizontal level of the shower nozzle 18 of measuring as required again, along the guide rail on vertical sliding moving platform 2, moves left and right horizontal sliding table 3.When moving to the position of suitable measurement, screw four bolts 8, allow rubber blanket 12 that bolt is adhered be close on the guide rail of vertical sliding moving platform 2 below below, make horizontal sliding table 3 be fixed on measuring position.
Subsequently, open sprayer, start to measure.The droplet of shower nozzle 18 ejections enters into droplet gathering-device 5, is measured the quality that sprays into droplet by droplet weighing device 4.Meanwhile, droplet electric quantity measuring device 6 is connected with droplet gathering-device 5 use wires, measures the carried charge of droplet.Difference between current between adjacent two moment is compared with of poor quality, can be obtained the specific charge of droplet in this time period.
After a shower nozzle measurement completes, close sprayer, open droplet gathering-device 5 water delivering orifice 9 below, discharge the liquid spraying in droplet gathering-device 5 while last time measuring.Or, by 4 peelings of droplet weighing device, after all shower nozzles that need to measure of this sprayer have all been measured by the time, discharge again all liq.Then four bolts 8 are unscrewed, horizontal sliding table 3 is moved to the next correct position of measuring, then screw bolt 8, measure.So repeat, until all, need the shower nozzle of measuring all to measure complete.
