    • Apparatus for delivering a fluid, especially for delivering colourants or the like to a premixer stage of plastics forming equipment, for example an injection moulder of extruder is described. The apparatus includes a fluid supply means (4, 200) connected to a reservoir (8, 208) which is arranged to concertina between minimum and maximum volume conditions. The reservoir (208) is connected via pipeline (24) and peristaltic pump (26) to a delivery means which is arranged to deliver the fluid to a desired location. When the fluid supply means (200) is empty, the level of fluid in the reservoir (208) will fall below the level of a capacitance sensor (32) which will sense the presence of air and cause a signal to be output to alert an operator to change fluid supply means (4). The fluid supply means may be changed before the reservoir is empty of fluid and, accordingly, the process may be operated continuously, even during the replacement of a reservoir (4).
    • 描述了用于将流体,特别是用于将着色剂等输送到塑料成形设备的预混合器阶段的设备,例如挤出机的注塑机。 该装置包括连接到储存器(8,208)的流体供应装置(4,200),该储存器布置成在最小和最大体积条件之间旋转。 储存器(208)通过管道(24)和蠕动泵(26)连接到输送装置,输送装置被布置成将流体输送到期望的位置。 当流体供应装置(200)为空时,储存器(208)中的流体水平将下降到电容传感器(32)的水平以下,这将感测到空气的存在并导致输出信号以警告 操作者改变流体供应装置(4)。 流体供应装置可以在储存器空出流体之前改变,并且因此即使在更换储存器(4)期间,该过程也可以连续地操作。
