电场仪球形传感器涂覆方案研究

电场仪涂层的均匀性是影响其电场测量精度的重要因素,手工喷涂方案难以满足涂层的均匀性需求,且工艺不稳定.为解决电场仪球形传感器涂层喷涂的均匀性问题,提出了一种新的喷涂方案,采用机械臂带动喷枪运动,在喷枪与球形传感器之间增加带开口的挡板,通过改变开口的形状控制喷涂到球形传感器上的涂料量,从而实现涂层的均匀性.初步实验得到的结果看,涂层的均匀性较好,而且提高了涂层质量,因此该方案能够最终解决电场仪球形传感器的涂覆问题.

STUDY ON THE COATING SCHEME OF THE ELECTRIC FIELD DETECTOR SPHERICAL SENSOR

The uniformity of the coating covering the electric field detector is a important factor which effects the accuracy of the electric field measuring,it is difficult to satisfy the uniformity requirement by coating manually,and this technology is not stable. In this paper we present a new scheme,in this scheme the ejection gun is driven by a mechanical arm and a damper is inserted between the gun and the spherical sensor,by changing the shape of the split in the damper the paint mass drops to the spherical sensor can be controlled,so the uniformity of the coating can be realized. From the preliminary results,the coating has good uniformity,so this scheme can resolve the coating problem of the EFD spherical sensor at last.
