Title:
DIRECT CURRENT PERMANENT MAGNET SELF-PRIMING COMPOSITE SHIELDING PUMP
Document Type and Number:
WIPO Patent Application WO/2023/279689
Kind Code:
A1
Abstract:
A direct current permanent magnet self-priming composite shielding pump, comprising a pump inlet (1), a gas-liquid mixing chamber (2) (or injector), a centrifugal terminal, a buffer boost chamber (7), a gas-liquid separation chamber (8) and a pump outlet (9). The pump inlet (1) is connected to an inlet of the gas-liquid mixing chamber (2) (or injector), an outlet of the gas-liquid mixing chamber (2) (or injector) is connected to an inlet of the centrifugal terminal, an outlet of the centrifugal terminal is in communication with an inlet of the buffer boost chamber (7), an outlet of the buffer boost chamber (7) is in communication with the gas-liquid separation chamber (8), and the gas-liquid separation chamber (8) is in communication with the pump outlet (9). The buffer boost chamber (7) is used for quickly decelerating and pressurizing a high-speed pressured fluid. In an exhaust and self-priming phase, the flow speed of the gas-liquid mixed fluid is lowered and bubble bursts are reduced at the same time. In a non-exhaust phase, the flow resistance is reduced, the pressure loss is lowered, and at the same time the fluid at the outlet of the centrifugal terminal is buffered and pressurized.
