输送泵和输送泵附件
摘要：
一种输送泵，包括限定入口和出口的壳体。主泵路径和旁路路径设置在入口和出口之间。电动机与主泵路径流体连通，并且被配置成被通电以移动流体通过主泵路径和旁路路径。该流体的移动指示在入口和出口之间发生非虹吸状况。流动传感器设置成与旁路路径流体连通，并且被配置成产生指示旁路路径中的流体流动速率的流动速率信号。控制器与流动传感器通信以用于接收流动速率信号，并且被配置成当流动速率信号满足指示在入口和出口之间发生的虹吸状况的第一阈值时，使电动机断电。
摘要（英）：

A transfer pump includes a housing defining an inlet and an outlet. A main pump path and a bypass path disposed between the inlet and the outlet. A motor is in fluid communication with the main pump path and is configured to be energized to move a fluid through the main pump path and the bypass path. The fluid movement being indicative of a non-siphoning condition occurring between the inlet and the outlet. A flow sensor is disposed in fluid communication with the bypass path and being configured to generate a flow rate signal indicative of a flow rate of fluid in the bypass path. A controller in communication with the flow sensor for receiving the flow rate signal and being configured to de-energize the motor when the flow rate signal satisfies a first flow rate threshold indicative of a siphoning condition occurring between the inlet and the outlet.
