将喷雾所需喷头安装在喷头座1中，依据所选喷头和所设定喷雾压力作为参考来确定电极5和弹簧6；将导线从导线孔2伸入电极槽4内，并于电极5相连，用绝缘材料将导线与导线孔2之间的空隙进行填充密封；将电极5分别与活塞杆3和弹簧6相连，然后，将其装入电极槽4内；将喷头盖7与喷头座1通过紧固螺栓固定，将喷头座1卡接并旋紧固定在喷杆上，将导线与外接高压静电发生器连接。开启液泵，将溶液泵入喷头，液体通过喷头形成喷雾，同时，在液体压力施加在活塞杆3上，在活塞杆3和弹簧6的共同作用下，使得电极5稳定在预定位置上，接通电源，使电极带电，形成感应电场，对喷雾雾滴进行感应荷电。当液压发生变化时，如压力减小，活塞杆3上所受压力减小，弹簧6将推动电极5向上移动；反之，当压力增加，活塞杆3上所受压力增大，活塞杆3将推动电极5向下移动。如此，实现，电极5的位置随压力变化自动调整，从而使得在压力变化时，静电喷嘴总能达到最佳的荷电效果。Install the nozzle required for spraying in the nozzle holder 1, and determine the electrode 5 and the spring 6 according to the selected nozzle and the set spray pressure as a reference; extend the wire from the wire hole 2 into the electrode slot 4, and connect to the electrode 5. , Use insulating material to fill and seal the gap between the wire and the wire hole 2; connect the electrode 5 to the piston rod 3 and the spring 6 respectively, and then install it into the electrode slot 4; connect the nozzle cover 7 to the nozzle seat 1 Through the fastening bolts, the nozzle base 1 is clamped and screwed to the spray rod, and the wire is connected with the external high-voltage electrostatic generator. Turn on the liquid pump and pump the solution into the spray head. The liquid is sprayed through the spray head. At the same time, the liquid pressure is applied to the piston rod 3, and the electrode 5 is stabilized at the predetermined position under the combined action of the piston rod 3 and the spring 6. The power is turned on to charge the electrodes to form an induction electric field, which induces charging of the spray mist droplets. When the hydraulic pressure changes, if the pressure decreases, the pressure on the piston rod 3 will decrease, and the spring 6 will push the electrode 5 upward; on the contrary, when the pressure increases, the pressure on the piston rod 3 will increase, and the piston rod 3 will Push the electrode 5 to move down. In this way, it is realized that the position of the electrode 5 is automatically adjusted with pressure changes, so that when the pressure changes, the electrostatic nozzle can always achieve the best charging effect.
