Description

Water pump impeller structure

Technical Field

The utility model relates to the technical field of water pumps, in particular to a water pump impeller structure.

Background

The water pump is a machine for pumping energy liquid, which is a machine for converting mechanical energy of a prime motor into pumped liquid potential energy, and can pump liquid from low to high or far under the drive of a power machine, and is mainly composed of a motor, a pump body and an impeller.

After the motor is started, the impeller rotates at a high speed in the pump body, liquid in the pump body rotates along with the impeller, the liquid is thrown out by the impeller at the water outlet under the action of centrifugal force, the thrown-out liquid gradually slows down in the diffusion chamber of the pump body, after the liquid is thrown out, a vacuum low-pressure area is formed at the center of the impeller, and the liquid in the liquid pool flows into the water pump through the water inlet pipe under the action of external atmospheric pressure. As the volume of the diffusion chamber of the pump body is constant, the pressure is gradually increased along with the increase of the thrown liquid, and finally the liquid is discharged from the outlet of the water pump, so that the liquid is continuously sucked up from the liquid pool and then is continuously discharged from the outlet of the water pump.

Most of the existing impellers are of fixed structures, namely, the volume between the impeller and a diffusion chamber of a pump body is a fixed value, when the output end of a motor starts to rotate or rotates at a low speed, the negative pressure suction formed at the center of the impeller is smaller, the water flow lift at a water outlet is smaller because the volume of the diffusion chamber is unchanged, after the model of the water pump is determined, the power consumption of the water pump is proportional to the actual flow of the water pump, the flow of the water pump is reduced along with the increase of the lift, namely, the power consumption of the water pump is increased along with the decrease of the water flow lift at the water outlet of the water pump, and even the phenomenon of motor overload occurs.
