每台电子计量泵都经试验，符合规定的技术规范和**标准。
正确、小心地搬运、安装和操作有助于确保无故障安装。
• 搬运泵时要小心。跌落或重击不仅会造成泵的外部损坏，而且还会损坏其内部电子部件。
• 泵安装地点的环境温度不能超过104°F (40°C)。泵可防水防尘，可用于室外，但是不能浸在 水中使用。不要在直射阳光下运行，防止泵的内部温度升高。
IA小心 丨电磁线圈外壳、泵头和泵壳可能高温160°F(70°C),不可接触。
• 泵的安装地点要方便将来的维护和检验。泵要固定，避免振动。
• 在将管道安装到阀门组件上之前，必须先卸下保护帽。使用规定尺寸的管道。将管道牢固地 连接到吸入端，防止外部空气进入。确保排出端无液体泄漏。
• 小心检查装置电压与计量泵数据标签上指示的电压是否-致。大多数型号的泵配有-个三叉 塞。务必确保计量泵接地。断开连接时，不要拔电线，而是用手指夹住塞子，然后拔出。不 要使用与重型电气设备共用的插座，重型电气设备会产生冲击电压。冲击电压会使泵内的电 子电路产生故障。
・擅自改动电气装置有潜在危险。务必将化学药品和泵装置放在儿童不能接触到的地方。
• 决不要在计量泵运行时修理或移动泵。-定要断开电源。为了**，在操作化学计量泵或靠 近泵时务必穿戴防护服(防护手套和护目镜)。
• 大多数.型号都配备带有管接头的放气阀。启动时，应在泵室内没有流体时实施空气吹扫。为 确保**，将回流管道连接到放气阀，并使流体旁路回到储槽或合适的排液管。
• 为了使体积输出准确，泵必须在典型的运行条件下标定。
• 使用的化学药品可能有危险，应小心按照标签上的警告信息使用。遵守每种化学药品的说明。 不要因为化学药品相似而认为它们相同。务必将化学药品储存在**地点，远离儿童和其他 人员。我们对误用计量泵给送的化学药品不负责任。务必将泵送流体的材料**数据表
(MSDS) 置于随手可得 处。
・发运前已经用水对所有泵做了预试验，如果用户泵送的材料会与水起反应(即硫酸、聚合物), 应卸下泵头，彻底干燥。阀座、球形阀、密封垫和隔板也应干燥。在投运泵前，应严格遵守 本程序。
• 阀芯上应压印指示流体流向。安装时一定要使箭头朝着流量方向，从上到下阅读标记。
• 计量危险材料时，不要使用塑料管，严格地使用合适的刚性管。有关专用适配器或阀门组件 信息请咨询供应商。
・计量泵不可用于处理或计量易燃液体或材料。
PULSAtron Series E Plus Metering Pump
504 GPD @ 20 PSI, 230 VAC4-20 mA Input with Dual Manual Control and Stop Function Input
Stroke frequency control via 4-20 mA signal input, manual stroke length control. Stroke frequency is manually adjustable when in local control. Includes stop function input.
General Description
Pulsafeeder PULSAtron Series E Plus chemical metering pumps are positive displacement, diaphragm type pumps. Output volume is adjustable while pumps are in operation from zero to maximum capacity. The PULSAtron Series E Plus contains a highly reliable timing circuit as well as circuit protection against voltage and current upsets. This pump features solenoid protection by thermal overload with auto-reset. The Series E Plus guided check valves, with their state-of-the-art seat and ball designs, provide precise seating, and excellent priming and suction lift characteristics. Our timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances.
Pump Controls
Adjustment is by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency. Both knobs are located opposite the liquid handling end. Automatic control via 4-20mA DC and stop function inputs. Auto-Off-Manual switch.
Drive Assembly
The pump drive is totally enclosed with no exposed moving parts. Electronics are housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption is 130 Watts.
Materials of Construction
See Specifications tab. Chemical metering pump housing shall be of chemically resistant PBT thermoplastic. All exposed fasteners are stainless steel. Valve seat and seal ring are renewable by replacing the cartridge valve assembly.
