泵用滑动部件和泵运转状态检测系统
摘要：
本发明的目的在于提供一种泵用滑动部件、以及使用该泵用滑动部件的泵的泵运转状态检测系统，根据本发明，即使因为以与其他部件接触的状态相对于该其他部件产生滑动而生成磨损物等，也能够迅速且准确地掌握产生磨损物等的情况；泵运转状态检测系统(10)包括：单轴偏心螺杆泵(20)、能够检测出从单轴偏心螺杆泵(20)吐出的流体中的金属粉的检测装置(100)以及控制装置(120)；在单轴偏心螺杆泵(20)的内部，设有被配置为露出于供流体流动的流体输送路(56)内的定子；随着单轴偏心螺杆泵(20)进行工作，定子以与转子接触的状态相对于该转子产生滑动；定子由树脂或橡胶制成，且按重量比计含有10％～30％的金属粉。
摘要（英）：

Provided are a sliding member for a pump in which generation of a wear substance and the like can be quickly and accurately grasped even if the wear substance and the like are generated when the sliding member for a pump slides while being in contact with another member, and a pump operation state detection system for a pump using the sliding member for a pump. A pump operation state detection system (10) includes a uniaxial eccentric screw pump (20), a detection device (100) capable of detecting metal powder in a fluid discharged from the uniaxial eccentric screw pump (20), and a determination device (120). In the uniaxial eccentric screw pump (20), a stator is arranged so as to be exposed to a fluid conveyance path (56) through which the fluid flows. The stator is configured to slide while being in contact with a rotor along with operation of the uniaxial eccentric screw pump (20). The stator is made of a resin or a rubber and contains 10% to 30% of metal powder in terms of a weight ratio.
