电泳槽液冷却系统设计中英对照版
Paint Cooling 槽液冷却
All modern electrocoat formulations operate at higher temperatures compared with the operating temperatures of the original cathodic products. Future developments are expected to follow this trend and should, thus, permit a reduction in the cooling load design for electrocoat systems.
当今所有电泳漆组成的,操作温度都比最初的阴极电泳漆操作温度高,预计未来的发展趋势也是这样,故此需设有可降低厚膜电泳漆系统温度的冷却系统负载。
The cooling unit must be capable of holding 70° F (21°C) under full-load operation. The temperature should not vary more than one degree F above or below a given setting. Normal operating temperatures are 85-95°F (29-35° C).
电泳漆冷却装置必须具有在满负荷生产情况下保持漆液在70°F(20°C)的能力,温度与给定温度的偏差不能大于1°F,一般的操作温度是85-95°F (29-35°C)。
For older cathodic formulas (3002 & 3002V), the cooling units should be capable of holding 60°F (15°C) under full operation. The temperature should not vary more than one degree F above or below a given setting. Normal operating temperatures are 80-82°F (27-28°C).
对老的电泳漆系统来说,冷却装置必须在满负荷生产情况下保持其在60°F(15°C )的能力。温度与给定温度的偏差不能大于1°F。一般的操作温度是85-82°F
Chiller and heat exchanger equipment should be designed to operate at the highest anticipated. A city water connection should be available for use on the heat exchanger in the event of failure of the chilling unit. Paint pressure should always exceed chilled water pressure to prevent paint contamination. In cooler weather, a cooling tower may be used, permitting by-passing of the chillers.
制冷剂及热交换器要以其在最高的预计电流强度下工作来设计。自来水的连接是为了制冷机在冷却过程中发生故障时使用。槽液的压力要保持超过冷却水的压力以防止槽液污染。在冷天时,可以用冷却塔,而不需要通过制冷机。
Both plate-and-frame and shell-and-tube heat exchangers perform equally well in cathodic electrocoat systems. Paint should be filtered before entering the heat exchanger, especially with the plate-and-frame units. In both types of equipment, stainless steel should be used for fabricating heat exchanger surfaces.
板柜式和榖管式热交换器都适用于阴极电泳系统,槽液在进入热交换器之前要经过滤,特别用板柜式热交换器时更为重要。这两种热交换器都要用不锈钢制造换热表面。
