可调堰
An adjustable weir plate at the exit end of the tank is recommended to maintain tank level and to permit surface movement of the paint. The surface flow of the paint carries foam and dirt away from the entrance to the weir. Free fall of paint into the weir should be limited to less than 6 inches (15 cm.) to prevent foaming. Sloped-bottom weir boxes with eductor agitation are recommended. Weir box configuration is dependent upon the type of pumps used for circulation (see Figure 4).
建议在电泳槽的出口端设可调的堰板以维持槽的液位并使槽液表面流动时会将泡沫和杂质污物从电泳槽带入溢流槽，漆液到溢流槽的落差应保持在6英寸（15cm）以内来防止起泡。建议在溢流槽底加喷嘴以保持搅拌。溢流槽的设计依使用的循环泵类型而定。（见图4）
Freeboard and Overflow
槽沿超出液面高度与溢流
To prevent the paint tank from overflowing in the event of material addition errors, the tank should be designed with approximately 9 inches (23 cm.) freeboard above the normal operating level. This margin should be sufficient to permit pumping of the first recirculated rinse tank back into the tank for easy cleaning of the rinse tank. An overflow pipe of at least 3 inches diameter should be installed near the top of the tank to drain into the dump tank to permit material recovery. This pipe should be located at least 9 inches above the normal operating level of the main tank. If the dump tank is installed below the main tank be certain that the building structure can support the additional weight of a full dump tank should it be filled completely. High level alarms should be installed to alert system operators and plant security should problems occur.
为防止漆液因偶然的加料失误而从槽中溢出，电泳槽应设计成其槽沿超出正常工作液面约9英吋（23cm）。这个安全系数足以满足在清洗槽清理时，将第一循环冲洗槽液泵入电泳槽的需要。在靠近槽顶处要装一个直径不小于3英寸的溢流管通向贮存槽，以便于材料回收。此管应设在主槽正常工作液位置上至少9英寸的位置，无疑建筑结构要能支撑注满时的总重量。要装高液位报警器及设备报警器，以保证系统安全进行，不发生事故。运输链的接油盘也必须在适当的高度上，以防止在高液位情况下被淹没。
