The embodiment of the invention provides an integrated pipeline pump with high cavitation resistance. The integrated pipeline pump comprises a pump shell, a hub, a pump impeller and an inducer. A motor stator arranged coaxially with the pump shell is arranged on the inner side wall of the pump shell. The hub is coaxially installed in the pump shell. The pump impeller is installed on the hub in a rotating manner. A rim of the pump impeller is provided with a motor rotor. The motor rotor is arranged corresponding to the motor stator. The inducer is coaxially connected with the pump impeller. Theinducer is located on the upstream of the pump impeller. According to the pump, compactness of the overall structure of the pipeline pump is ensured, based on the preliminary supercharging effect ofthe inducer to fluid, thus the fluid does not generate cavitation any more when flowing through the pump impeller, the pump impeller supercharges and pumps the fluid again, the cavitation resisting performance of the pipeline pump is effectively improved, and the fluid can be pumped in a direct-in and direct-out form.
Description
technical field [0001] The invention relates to the technical field of pipeline pumps, in particular to an integrated pipeline pump with high cavitation resistance. Background technique [0002] The axial flow pump is a pump that generates driving force on the liquid by the blades of the rotating impeller, so that the liquid is transported in the axial direction. A traditional axial flow pump consists of a coaxially arranged pump housing, pump impeller and guide vane body, the pump impeller and guide vane body are arranged in sequence along the water flow direction in the pump housing, and the pump impeller and guide vane body are connected on the same shaft , the rotation of the pump impeller is driven by the rotating shaft to achieve the purpose of pumping the water flow. Due to the limitation of the arrangement of the rotating shaft, the water outlet side of the pump casing must be designed as an elbow structure, so that the flow of the inlet and outlet of the axial flow...
