    摘要： A non-clogging type pump impeller includes: a fluid passage provided in an approximately cylindrical body and connecting a suction port to a discharge port. The fluid passage has a vortex shape as viewed from an axial direction. A first recess, which is sunk downwardly in the axial direction, is formed on a first end surface of the approximately cylindrical body so as to surround a boss. A second recess, which is sunk upwardly in the axial direction, is formed on a second end surface of the approximately cylindrical body so as to surround the suction port. At least one communication hole provides fluid communication between the first recess and the second recess. Sewage in the second recess is introduced into the first recess through the at least one communication hole to thereby effectively remove an air pocket trapped on the first end surface of the impeller and in the first recess.

    摘要： A non-clogging type pump impeller (1) includes: a fluid passage (18) provided in an approximately cylindrical body (10) and connecting a suction port (13) to a discharge port (14). The fluid passage (18) has a vortex shape as viewed from the axial direction. A first recess (21), which is sunk downwardly in the axial direction, is formed on one end surface (11) of the body (10) so as to surround a boss (12). A second recess (22), which is sunk upwardly in the axial direction, is formed on the other end surface (15) of the body (10) so as to surround the suction port (13). One or more communication hole (23) provides fluid communication between the first recess (21) and the second recess (22). Sewage in the second recess (22) is introduced into the first recess (21) through the communication hole (23) to thereby effectively remove air pocket trapped on the upper end surface (11) of the impeller (1) and in the first recess (21).

    摘要： The present invention relates to a pump for delivering under pressure various liquids including water. The temperature of the handled liquid in a pump casing (1) is detected by a thermistor (51). If an increase in the temperature per time of the handled liquid is greater than a predetermined value, then the pump is shut down, or the flow rate or pressure of the liquid is changed depending on the temperature of the handled liquid detected by the thermistor based on a predetermined control program.

    摘要： A submersible motor pump includes a water jacket having a circulation passage of a coolant, a centrifugal impeller for circulating the coolant, a suction passage configured to provide fluid communication between the circulation passage and a fluid inlet of the centrifugal impeller, and a discharge passage configured to provide fluid communication between a fluid outlet of the centrifugal impeller and the circulation passage. The discharge passage includes a heat-exchange passage formed by two wall surfaces, one of which is constituted by a member which contacts a liquid conveyed by a main impeller. The heat-exchange passage has a circular shape extending radially outwardly from the fluid outlet of the centrifugal impeller. The heat-exchange passage includes at least one axial passage section having a length component in an axial direction of the rotational shaft.

    摘要： A centrifugal pump includes at least one impeller (11) fixed to a main shaft (10) and at least one casing which houses the impeller and is formed through press working of sheet metal such as a steel plate. The centrifugal pump further includes a casing cover configured to seal an open end of the casing hermetically, and a shaft seal device (12) provided at a portion where the main shaft passes through the casing cover. The casing cover has a thick member (6) made of castings, and a thin corrosion-resistant lining member (40) which is tightly fixed to the thick member.
