Self-storage centrifugal pump

Abstract

The present invention relates to the field of centrifugal pumps, specifically a self-storage centrifugal pump, comprising a centrifugal pump body, the centrifugal pump body is provided with a water inlet pipe and a water outlet pipe, and an operation box is fixed on the output shaft of the centrifugal pump body , the operation box is fixed with a water storage tank, the water storage tank is fixedly connected with a water inlet through the side wall of the operation box, the bottom of the water storage tank is fixedly connected with a first drain pipe, and the operation box is fixedly connected with a square box, the square box is slidably connected with a first sliding plate, the first sliding plate is provided with a round hole, and the bottom of the square box is fixedly connected with a second drain pipe, which can realize the water collected inside the water storage tank The moment the centrifugal pump shuts down, it stops losing water, so that the water resources inside the water storage tank are always full of water. The centrifugal pump can realize automatic water storage, and there is no need to repeatedly add water resources for the centrifugal pump to start and infuse, which improves the operation of the centrifugal pump. s efficiency.

Description

Technical field [0001] The present invention relates to the field of centrifugal pumps, and in particular, a self-contained centrifugal pump. Background technique [0002] The centrifugal pump is very widely used in life. It is almost an indispensable device in the process system. The centrifugal pump is small, and the operation is simple, the service life is the outstanding advantage of the centrifugal pump. If the pipe delivery system is used as a person The vascular circulation system, then the centrifugal pump is equivalent to the heart of the blood delivered. [0003] Before the centrifugal pump, the pump body must be covered with water, forming a vacuum state, when the impeller on the centrifugal pump is rapidly rotated, the blade urges water to rapidly rotation, the rotating water flew from the impeller under the action of centrifugation, pump After the water is thrown, the center portion of the impeller forms a vacuum region, and the water is discharged from the water pum...

AI Technical Summary

Problems solved by technology

[0003] Before the centrifugal pump works, the inside of the pump body must be filled with water to form a vacuum state. When the impeller on the centrifugal pump rotates rapidly, the blades make the water rotate rapidly, and the rotating water flies away from the impeller under the action of centrifugal force. After the water inside is thrown out, the central part of the impeller forms a vacuum area, which realizes the suction of water from the water inlet pipe of the pump body and discharges it from the water outlet pipe. However, the existing ways of filling the tank with centrifugal pump water are all manually operated. , every time the centrifugal pump is started, watering needs to be repeated, which reduces the efficiency of the centrifugal pump
