Spiral automatic controlled water pump

Abstract

The invention relates to a water pump, in particular to a spiral automatic controlled water pump. The spiral automatic controlled water pump comprises a pump body, a motor arranged in the pump body, a water inlet arranged at one end of the pump body, a water outlet arranged at the other end of the pump body and a turbine arranged on an output shaft on the motor; and the turbine is arranged at the water inlet of the inner cavity of the pump body. The pump body comprises a shell, a water inlet cover and a water outlet cover; wherein the water inlet cover and the water outlet cover are respectively connected with the shell by screw thread while the motor is arranged in the inner cavity in the middle of the shell. The shell is provided with a water flow channel, and the water flow channel is communicated with the water inlet and the water outlet. The invention has the advantages that: 1, water at the water inlet can not return during the rotation of the turbine, thus flow velocity is not influenced; 2, water enters from the water inlet and flows through the water flow channel, heat produced by the motor is transferred to the water flow channel and is taken away by flowing water, thus the motor can be cooled in time; 3, the volume is small and weight is light; 4, use is safe and reliable, life is long, the water pump is quiet, and production and installation are convenient.

Description

Technical field: [0001] The invention relates to a water pump, in particular to a screw type automatic control water pump. Background technique: [0002] In the prior art, the water pump is mainly composed of a pump body, a motor, and an impeller. The impeller is fixed on the output shaft of the motor, and the motor is located on one side of the pump body. The water in the water port generates enough pressure in the pump body and is discharged from the drain port of the pump body. The disadvantages of the water pump are: 1. When the water pump is working, the motor drives the impeller to rotate. During the rotation of the impeller, under the centrifugal force, the water flow will be subjected to the centrifugal force F perpendicular to the rotating shaft, such as figure 1 As shown, under the action of the centrifugal force F, the water flow will generate a force directly acting on the water pump casing 7, and the water flow will cause part of the water to flow back, thereby...

AI Technical Summary

Problems solved by technology

The disadvantages of this water pump are: 1. When the water pump is working, the motor drives the impeller to rotate. During the rotation of the impeller, under the centrifugal force, the water flow will be subjected to the centrifugal force F perpendicular to the rotating shaft, such as figure 1 As shown, under the action of this centrifugal force F, the water flow will generate a force directly acting on the water pump casing 7, and the water flow will cause part of the water to flow back, thereby affecting the flow speed of the water.

2. The housing where the motor is located is always in non-flowing water, which leads to poor cooling effect of the motor, and the heat generated by the motor cannot be dissipated in time, so it is often necessary to use a high-power motor, resulting in a large volume of the motor

Since the water flow needs to pass through the pipeline in the permanent magnet rotor, if the water volume is required to be large enough, the diameter of the rotor pipeline needs to be large enough, which will greatly increase the volume of the entire product

In addition, in this technical solution, the worm impeller is located in the pipe of the rotor, and when it works, it pushes the water flow in, and the flow rate of the water flow is the same as the propulsion amount, thus limiting the flow rate of the water flow
