    摘要： A submergible motor pump including a vortex impeller (2) attached to an end of a motor shaft (3), a pump casing (21,23) attached to a motor casing (25) and accommodating the impeller (2) therein, a strainer (9) attached to the pump casing for introducing water to be sucked into the pump casing, and a bottom plate (11) supporting the strainer (9) from therebelow is disclosed. The pump casing comprises an intermediate casing member (21) and a lower casing member (23), which are detachable from each other. The pump casing has a configuration in which the upper side is open so that the flow passage formed in the lower casing member does not have a bag-shaped configuration. A plurality of legs (29) are provided on the lower side of the lower casing member (23) as being integral portions thereof. The legs (29) are spaced apart from each other and extend as far as the outer peripheral end of the lower casing member (23). The strainer (9) is provided around the outer peripheral end of the lower casing member in such a manner as to surround the outer periphery of the lower casing member (23). The lower casing member (23) is clamped between the bottom plate (11) and the intermediate casing member (21) by means of clamping bolts (13), thereby assembling together the bottom plate (11), the lower casing member (23) and the strainer (9) in one unit.

    摘要： Disclosed is a submerged motor pump of the type in which a motor is installed inside an outer casing so as to define an annular passage therebetween and a pumped liquid is discharged to the outside through the annular passage while cooling the entire periphery of the motor. The outer casing is formed using a resilient material and is retained at its upper and lower ends by rigid members. Accordingly, the outer casing is deformable in the radial direction so as to absorb external force, for example, impact force, which may be applied thereto during transportation.

    摘要： A bearing device for use in a pump which has a bearing member comprising a hard and brittle material made of ceramics such as silicon carbide (SiC). The bearing device comprises a bearing housing, a ceramic bearing member housed in the bearing housing and supporting a shaft, an elastic material around the ceramic bearing member for preventing the ceramic bearing member from being broken, and a thrust collar for preventing fragments of the ceramic bearing member from being scattered when the ceramic bearing member is broken.

    摘要： A full-circumferential flow pump includes an outer cylinder and a motor housed in the outer cylinder. The motor has a motor frame, a stator disposed in the motor frame, a main shaft, a rotor mounted on the main shaft and rotatably disposed in the stator. The outer cylinder defines an annular space defined around the motor frame, the outer cylinder having a pump suction port defined therein for introducing a fluid therethrough into the annular space. A pump unit is mounted on an end of the main shaft, and the outer cylinder has a discharge window defined therein for discharging a fluid from the pump unit. A discharge case is mounted on an outer circumferential surface of the outer cylinder in communication with the discharge window, the discharge case having a pump discharge port.
