摘要： A fluid pumping assembly for pumping particulate material includes a pump housing defining a pump cavity including a pumping chamber for handling particulate material, a motive fluid chamber, and a moveable diaphragm. The fluid pumping assembly also includes devices for loading particulate material into the pumping chamber, and for injecting a high pressure, high volume purging fluid into the pumping chamber. Further, the fluid pumping assembly includes a control system having a control valve for shutting off flow of high pressure, high volume purging fluid into the pumping chamber when particulate material is being loaded into the pumping chamber, thus enabling dense phase loading of particulate material, and thereby optimizing a particulate material pumping capacity of the fluid pumping assembly.
摘要翻译：用于泵送颗粒材料的流体泵送组件包括限定泵腔的泵壳体，泵壳体包括用于处理颗粒材料的泵送室，运动流体室和可移动隔膜。流体泵送组件还包括用于将颗粒材料装载到泵送室中的装置，以及用于将高压，高体积的清洗流体喷射到泵送室中的装置。此外，流体泵送组件包括控制系统，该控制系统具有控制阀，该控制阀用于在将颗粒材料装载到泵送室中时关闭高压，大体积清洗流体进入泵送室的流动，从而使颗粒材料能够进行密相加载，从而优化流体泵送组件的颗粒材料泵送能力。
