Self-water-storage type centrifugal pump

Abstract

The invention relates to the field of centrifugal pumps, in particular to a self-water-storage type centrifugal pump. The self-water-storage type centrifugal pump comprises a centrifugal pump body, awater inlet pipe and a water outlet pipe are arranged on the centrifugal pump body, an operation box is fixed to an output shaft of the centrifugal pump body, a water storage tank is fixed to the operation box, the water storage tank penetrates through the side wall of the operation box to be fixedly connected with a water adding port, a first drainage pipe is fixedly connected to the bottom of the water storage tank, a square box is fixedly connected to the operation box, a first sliding plate is connected to the square box in a sliding mode, a round hole is formed in the first sliding plate,and a second drainage pipe is fixedly connected to the bottom of the square box. Water collected inside the water storage tank can stop running off at the moment when the centrifugal pump is shut down, water resources inside the water storage tank are always in a full-water state, the centrifugal pump can achieve automatic water storage, the water resources used for starting infusion of the centrifugal pump do not need to be repeatedly added, and the operation efficiency of the centrifugal pump is improved.

Description

technical field [0001] The invention relates to the field of centrifugal pumps, in particular to self-storage water centrifugal pumps. Background technique [0002] Centrifugal pumps are widely used in daily life and are almost indispensable equipment in the process system. The advantages of centrifugal pumps are small size, simple operation and long service life. If the pipeline transportation system is regarded as a personal The vascular circulatory system, then the centrifugal pump is equivalent to the heart that transports blood. [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 t...

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
