Title:
Sliding member for rotary positive displacement pump and rotary positive displacement pump operation state detection system
Document Type and Number:
Japanese Patent JP6352604
Kind Code:
B2
Abstract:
Provided are a sliding member for pumps in which generation of a wear substance is quickly and accurately grasped even if the wear substance is generated when the sliding member slides while being in contact with another member, and a pump operation state detection system using the sliding member. The pump operation state detection system includes a uniaxial eccentric screw pump, a detection device capable of detecting metal powder in a fluid discharged from the uniaxial eccentric screw pump, and a determination device. In the uniaxial eccentric screw pump, a stator is arranged so as to be exposed to a fluid conveyance path 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. The stator is made of a resin or a rubber and contains 10-30% of metal powder by weight ratio.
