    摘要： A diagnostic apparatus for a powder coating material pump. The diagnostic apparatus includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

    摘要： Apparatus for detecting powder flow along a powder flow path includes a light source and a light detector for detecting light from the light source directed across the powder flow path as powder flows through said powder flow path. A circuit receives the output from the light detector and determines an average or RMS of the signal received by the light detector. The circuit may determine whether there is flow or no flow of powder or whether there is a change in flow rate of powder. Preferably, the apparatus is used in combination with a dense phase powder pump, which causes the powder to flow in pulses from the pump outlet into the powder flow path. More preferably, the light source and detector are enclosed in a housing that is connected between the pump outlet and a powder feed hose which supplies powder to a spray gun or hopper.

    摘要翻译： 用于检测沿着粉末流动路径的粉末流动的装置包括光源和光检测器，用于当粉末流过所述粉末流动路径时检测来自指向粉末流路的光源的光。 电路接收光检测器的输出，并确定由光检测器接收的信号的平均值或RMS。 该电路可以确定粉末是流动还是没有流动，或者粉末的流速是否有变化。 优选地，该设备与致密粉末泵组合使用，其使得粉末以脉冲形式从泵出口流入粉末流动路径。 更优选地，光源和检测器被封装在壳体中，壳体连接在泵出口和将粉末供应给喷枪或料斗的粉末供给软管之间。

    摘要： A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.
