    • Electrically heated pumps are disclosed that include electric heating elements that are linked to a process controller. The disclosed pump designs can be applied to packed seal, lip seal, mechanical seal and magnetic drive pumps. For packed, lip and mechanical seal pumps, the external jacketing on the pump, including the head, casing, pressure relief valve and bracket, can be replaced with electric heating elements, such as flexible or custom form membranes, attached to the pump through the use of adhesive or mechanical fastening devices. For the magnetic drive pump, the external jacketing on the pump head, pressure relief valve and casing can be replaced with electric heating elements attached to the pump through the use of adhesive or mechanical fastening devices. For the bracket portion of the magnetic drive pump, the external jacketing can be removed and the heating element is attached to the canister that contains the liquid and that is located between the inner and outer magnetic drive assemblies. Through the use of appropriately placed thermocouples in the head, pressure relief valve, casing, bracket, canister, etc., and a single or multi-channel on/off, proportional or PID controller, the heating zones may be linked together, monitored and controlled to the application requirements. The disclosed pump designs may also be applied to auxiliary equipment such as strainers.
    • 公开了电加热泵,其包括连接到过程控制器的电加热元件。 所公开的泵设计可应用于密封件,唇形密封件,机械密封件和磁力驱动泵。 对于包装,唇形和机械密封泵,泵上的外部护套(包括头部,外壳,减压阀和支架)可以用电加热元件(如柔性或定制的膜)替换,通过 使用粘合剂或机械紧固装置。 对于磁力驱动泵,泵头上的外部护套,泄压阀和外壳可以通过使用粘合剂或机械紧固装置连接到泵上的电加热元件来代替。 对于磁力驱动泵的托架部分,可以去除外部护套,并且将加热元件附接到容纳液体并且位于内部和外部磁性驱动组件之间的罐。 通过在头部,压力释放阀,外壳,支架,罐等中使用适当放置的热电偶,以及单通道或多通道开/关比例或PID控制器,加热区可以连接在一起,监控和 控制到应用要求。 所公开的泵设计也可以应用于诸如过滤器的辅助设备。
