一种六氟化硫密度继电器和密度表的C形管及制作工艺
摘要：
本发明涉及一种六氟化硫密度继电器和密度表的C形管，包括C形管本体、基座和端座，基座和端座分别连接于C形管本体的两端，C形管本体、基座和端座的外表面均设置有锡层。一种六氟化硫密度继电器和密度表的C形管的制作工艺，包括以下步骤：（1）对C形管本体、基座和端座的表面进行酸洗，去除黄铜表面的氧化层和杂质；（2）再将C形管本体、基座和端座放入溶化的锡液中，在C形管本体、基座和端座的表面镀上锡层；（3）将基座和端座与C形管本体的两端通过锡焊连接。本发明的有益效果是：在C形管本体与基座和端座焊接时，因为其表面有一层镀锡，焊接时不会出现虚焊情况，而且焊接的效率和可靠性大大提高。
摘要（英）：

The present invention relates to a sulfur hexafluoride density relay and a density table C-shaped pipe. The pipe comprises a C-shaped pipe body, a pedestal and an end base, the pedestal and the end base are respectively connected with two ends of the C-shaped pipe body, and tin layers area arranged at the outer surfaces of the C-shaped pipe body, the pedestal and the end base. The making technology comprises the following steps: (1) performing pickling of the surfaces of the C-shaped pipe body, the pedestal and the end base, and removing the oxide and the impurity of the surface of the brass; (2) disposing the C-shaped pipe body, the pedestal and the end base into the dissolved tin liquor, and plating the tin layers on the surfaces of the C-shaped pipe body, the pedestal and the end base; and (3) connecting the pedestal and the end base with the two ends of the C-shaped pipe body through soldering. When the C-shaped pipe body is soldered with the pedestal and the end base, because there is a layer of tinning at the surface of the C-shaped pipe body, the pseudo soldering condition can not generate at soldering, and the efficiency and the reliability of the soldering are greatly improved.
