Abstract: 一种牺牲体,其使得对于泵内组件的汽蚀损害减轻。该牺牲体被安装在泵中,使得流动的液流经过该牺牲体,导致牺牲体向邻近汽蚀的流动的液流中脱落电子。过量的电子倾向于抑制氢离子的释放,这可减轻汽蚀。牺牲体由与泵组件相比对由于流动的液流所引起的汽蚀更不耐受的材料制成。在牺牲体上附有针,其用于浸泡在流动的液流中,以促进牺牲体的电子释放。

Abstract: A scroll compressor is provided that may include a casing; a drive motor provided at an inner space of the casing; a rotational shaft coupled to a rotor of the drive motor, and rotated together with the rotor; a frame provided below the drive motor; a fixed scroll provided below the frame, and having a fixed wrap; and an orbiting scroll provided between the frame and the fixed scroll, having an orbiting wrap so as to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the fixed wrap. In a state in which a center of the fixed scroll and a center of the orbiting scroll are substantially the same, an interval between the fixed wrap and the orbiting wrap gradually increases towards the suction chamber from the discharge chamber.

Abstract: In a vane rotary compressor, a discharge valve on a discharge flow channel communicates an operating chamber in a compression element with a discharge hole. The discharge valve is pushed from an opening portion of a discharge valve groove to an outer circumferential surface of a roller by a high-pressure refrigerant when pressure in an operating chamber is lower than the pressure of the high-pressure refrigerant. The discharge valve is pushed back into the discharge valve groove by the refrigerant pressure in the operating chamber when the pressure in the operating chamber is higher than the pressure of the high-pressure refrigerant. The discharge flow channel is closed by the outer circumferential surface of the discharge valve pushed out from the opening portion of the discharge valve groove and the outer circumferential surface of the roller, and opens when the discharge valve is pushed back into the discharge valve groove.

Abstract: A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body.
