摘要： The present disclosure provides a plunger type water pump, which mainly comprises a cavity body, a rotary main shaft and a plunger flow-distributing unit. The plunger distributing unit comprises a flat valve assembly, a plunger-shoe assembly and a supporting valve assembly; the plunger-shoe assembly divides the cavity body into a high-pressure cavity and a low-pressure cavity independent of each other; the high-pressure cavity is in fluid communication with the flat valve assembly; and the low-pressure cavity is in fluid communication with the supporting valve assembly. According to the present disclosure, the high-pressure water and the low-pressure water are independent of each other. This can ensure a high volumetric efficiency of the water pump under ultra-high-pressure conditions and surely provide the fluid supporting and lubrication for a friction coupling under high-speed heavy-load conditions so as to prolong the service life of the water pump.

摘要： An all-fiber Faraday rotator including a plurality of optical fibers doped, at unusually high concentrations of at least several tens of percent, with rare-earth oxides, an all-optical-fiber optical isolator employing a polarization-maintaining fiber-optic splitter, and a method of optically-isolating a laser source from unwanted feedback with such an optical isolator. In a case where the doping concentration exceeds 55 weight-%, the length of the Faraday rotator achieving a 45-degree rotation of the polarization vector of light guided by an optical fiber does not exceed approximately 10 cm.
