Novel water pump

Abstract

A novel water pump comprises a motor and a pump body. A sealing partition plate is arranged in the pump body and divides the interior of the pump body into a motor containing chamber and a sealing chamber. A motor is arranged in the motor placing chamber; the sealed chamber is internally composed of a water inlet chamber, a centrifugal chamber and a water outlet chamber; the water inlet chamber is sequentially communicated with the centrifugal chamber and the water outlet chamber; an output shaft of the motor penetrates through the sealing partition plate to the centrifugal chamber in the sealing chamber and is provided with an impeller; a water inlet pipe, a water outlet pipe and an exhaust pipe are arranged on the pump body, and a water inlet sealing valve is arranged in the water inlet chamber; compared with the design of a traditional integrated inner cavity, the water inlet chamber and the water outlet chamber are equivalent to a middle water storage chamber, the centrifugal chamber is used for pressurizing, flowing of liquid is drawn according to the high-pressure airflow principle, the water inlet chamber ensures that the water inlet amount is kept constant, and the sucked water amount is kept stable when the impeller rotates to generate centrifugal force; and the water pump can continuously and stably operate.

Description

【Technical field】 [0001] The invention relates to the field of water pumps, in particular to a novel water pump. 【Background technique】 [0002] A pump is a machine that transports or pressurizes a liquid. The water inlet, water outlet and impeller setting of the traditional water pump are all completed in the same cavity. It is easy to be affected by the original water pressure when pumping in, resulting in unstable state of the impeller when it rotates, and the centrifugal force generated is also affected, so that the water pump The overall power of the pump will change, which will greatly reduce the effect of pumping or boosting. At the same time, it will also affect the normal operation of the impeller. The impeller is easily damaged, and the service life of the pump is low; The air in the pump is discharged first. The traditional water pump discharges the gas through the water outlet. The gas discharge time takes 3-4 seconds. It is necessary to wait for the water pump ...

AI Technical Summary

Problems solved by technology

The water inlet and outlet of the traditional water pump and the setting of the impeller are all completed in the same cavity. It is easy to be affected by the original water pressure when pumping in, causing the state of the impeller to be unstable when it rotates, and the centrifugal force generated is also affected, so that the water pump The overall power of the pump will change, which will greatly reduce the effect of pumping or boosting. At the same time, it will also affect the normal operation of the impeller. The impeller is easily damaged, and the service life of the pump is low; The gas in the pump is discharged first. The traditional water pump discharges the gas through the water outlet. The gas discharge time takes 3-4 seconds. It is necessary to wait for the water pump to be filled with water before the gas can be discharged.
