摘要:
A permanent magnet canned motor pump features in its corrosion-protection housing which comprises a reinforced bracket (9), a motor casing (81) and a motor rear casing (82). The reinforced bracket (9) is made of corrosion-resistance plastic and the motor casing (81) and the motor rear casing (82) are made of aluminum alloy. Accordingly, the corrosion-protection housing is capable of preventing the corrosion of the chemical liquid to the aluminum alloy components. Beside, the permanent magnet canned motor pump provides a heat dissipation mechanism while meets the structural need of the corrosion-protection housing, so that the motor can dissipate heat in a sufficient rate.
摘要:
A structural improvement of the canned pump is to improve the stiffness of a stationary shaft (3) and, according to requirement, to dispose a monitor device (9). The method for improving the stiffness of the stationary shaft (3) includes axially inserting a shaft metal rear support (821a) of the metal structural of a motor rear casing (82) of a canned motor (8) into the inner side of a rotor yoke of an inner rotor of the canned motor, tightly attaching the shaft metal rear support (821a) to a rear shaft seat for improving the stiffness of the stationary shaft (3) by longer hold length, and for shortening an arm length of the composite force. The monitor device (9), used for detecting the wear of a bearing for enhancing the reliability and satisfying the driving requirement, is installed in the ring slot to be protected by the rear shaft seat.
摘要:
The disclosure offers a sealless magnetic drive pump for improving the stiffness of a stationary shaft (3), and more particularly to, a metal magnetic drive pump with an anti-corrosion casing liner (4a). The magnetic drive pump is used in manufacture processes related to corrosive fluid. The pump is especially used in a highly corrosive and high-temperature (up to 200°C) condition to improve the stiffness of a front support. The stationary shaft includes a metal front support (43) integrated with the pump casing (4) at a pump inlet (44) and encapsulated with a resin enclosure made of a fluoropolymer; a rear shaft seat (413) positioned on a sealed bottom side of a containment shell (41) for offering auxiliary support for the stationary shaft (3); an impeller (5) including a channel for reducing an inlet flow velocity to offer a low NPSHr.
