・ 如果排放管路中的流体压力低于环境压丿J.则在排放管路屮使用抗虹吸阀。如果注入点位于水
泵吸入端，或者靠着“负”压头，如在往下给送到井中时，则会发生虹吸作用。
管道
连接时使用提供的规定尺寸的管道。管道连接要牢固，防止化学药品泄漏和空 气进入。由于配件中使用塑料螺母，因此不可过度拧紧配件，即只能用手拧紧。 NPT（美国标准锥管螺纹）吸入阀和排放阀决不可拧得过紧。NPT 吸入阀和排 放阀只能拧紧到 25-35 英寸磅（4.5-6.3 kg/cm）。• 如果使用放气阀组件，则应可靠地连接一条回流管路（软管），回流管路连接回 到储罐。要避免化学药品可能造成的伤害，没有安装回流管路前决不要尝试使 用放气阀启动。
如果泵是架式安装，或安装在储罐顶上，进口软管应尽可能短。
• 提供一台背压/注入阀以保持计量性能。标准注入阀中的弹簧典型地增加 17-20 PSI（1.17 – 1.38 BAR）到管路压力上，H8 泵除外，这种泵增加 8-10 PSI（.55-.69 BAR）。注入阀必须安装在排放管路中。*好的方法是将注入阀安装在化学药 品注入点。
• 如果排放管会暴露于直射阳光，应使用黑色管来代替随泵提供的标准白色半透 明管。如需要黑色管，请与供应商联系。要防止堵塞或避免止回阀发生故障，请务必在吸入管末端安装一套过滤器组件这套底阀/过滤器组件务必安装在距离储罐底部上方 1-2 英寸（2-5 cm） 处，这样可以避免储罐底部可能积聚的固体堵塞过滤器。化学药品储罐和底阀/ 过滤器应定期清洗，确保连续**运行。如果溶液中周期性地沉淀出正在泵送 的化学药品，或者化学药品难以溶解或不能完全溶解（如氢氧化钙），则应在化 学药品储罐中使用混合器。这些在许多电动机配置和安装中都很容易提供。如 需要可与供应商联系。
• 如果注入点的稀释不是很快进行，则 会导致管道腐蚀。这个问题很容易避 免，只要遵守下面这一简单规则：安 装注入接头，使其端部伸入涉及管路 的液流中央。根据需要修整注入器顶端。
注：可提供适用于大型水管线路的延长注入组件。如欲了解更 多信息，请与供应商联系。
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.
