Abstract

The invention relates to the technical field of hydraulic pumps, and discloses a high-pressure centrifugal hydraulic pump. The centrifugal hydraulic pump comprises a pump shell, a pump shaft, a bearing, an impeller, an inlet and an outlet, wherein the bearing is fixedly connected to the pump shell; the pump shaft is connected in the bearing; the impeller is fixedly connected to the pump shaft, andcomprises hollow blades arranged in a seal manner; a front chamber, an impeller chamber and a flow passage which communicate sequentially from the inlet to the outlet are formed in the pump shell; and a flow limit passage communicates between the impeller chamber and the flow passage. According to the centrifugal hydraulic pump, the energy loss can be effectively reduced by arranging the open impeller and the flow limit passage.

Description

technical field [0001] The invention relates to the technical field of hydraulic pumps, in particular to a high-pressure centrifugal force hydraulic pump. Background technique [0002] A centrifugal pump refers to a pump that delivers liquid by the centrifugal force generated when the impeller rotates. The existing centrifugal pump sucks the liquid from the center of the circle, passes through the semi-open impeller, and through the rotation of the impeller, the liquid is thrown from the center of the impeller to the outer edge of the impeller and flows out along the discharge port with a higher pressure. [0003] The above-mentioned existing centrifugal pump, because there is no higher design for the size of the impeller outlet, and the impeller with a semi-open structure, causes excessive energy loss during high-speed rotation, and due to the centrifugal force, the loss of the bearing Also big. Moreover, when high pressure is required, multi-stage centrifugal pumps or mu...
