Water pump with double water outlets

Abstract

The invention discloses a water pump with double water outlets. The water pump with the double water outlets comprises a first side cover, a seal plate, a middle plate, a shell and a second side coverarranged sequentially, wherein a first pump chamber is formed between the first side cover and the seal plate; a second pump chamber is formed between the second side cover and the shell; an installation cavity is formed between the shell and the middle plate; a stator is arranged in the installation cavity; a rotor matched with the stator is arranged between the middle plate and the seal plate;a main shaft is arranged in the axis of the rotor; two ends of the main shaft extend toward the first pump chamber and the second pump chamber; two ends of the main shaft are each provided with at least one impeller in the first pump chamber and the second pump chamber; a first water inlet pipe and a first water outlet pipe leading to the first pump chamber are arranged on the first side cover; and a second water inlet pipe and a second water outlet pipe leading to the second pump chamber are arranged on the second side cover. The water pump with the double water outlets is reasonable in structure, the bearing wear is less, the service life is prolonged, and the practicability is improved; and through the structure, rotating force arms of the rotor are distributed uniformly, so that the efficacy generated by the rotating of the rotor is improved.

Description

technical field [0001] The invention relates to the technical field of centrifugal brushless water pumps, in particular to a double water outlet water pump. Background technique [0002] Conventional water pumps generate magnetic induction after the stator is energized, which drives the permanent magnet rotor to rotate, and a rotating shaft is fixed on the rotor, and one end of the rotating shaft is connected to an impeller. The bearing at one end bears a large force, while the other end bears a small force), resulting in a loud product and high noise; when the rotating shaft is equipped with multiple impellers at one end, this disadvantage is more obvious. Conventional water pump impellers are set on one side of the motor, resulting in a water pump that can only pump one type of liquid medium, or medium of the same temperature. When the product using the water pump needs to pump two different liquid media, two brushless water pumps are often required Therefore, it will inc...

Problems solved by technology

[0002] Conventional water pumps generate magnetic induction after the stator is energized, which drives the permanent magnet rotor to rotate, and a rotating shaft is fixed on the rotor, and one end of the rotating shaft is connected to an impeller. The bearing at one end bears more force, while the other end bears less force), resulting in loud noise and high noise; when the rotating shaft is equipped with multiple impellers at one end, this disadvantage is more obvious.

Conventional water pump impellers are set on one side of the motor, resulting in a water pump that can only pump one type of liquid medium, or medium of the same temperature. When the product using the water pump needs to pump two different liquid media, two brushless water pumps are often required Therefore, it will increase the volume of the product and increase the cost; for example, the non-gravity milk drinking machine needs a water pump to pump out the milk, but the product is divided into hot milk outlet and frozen milk outlet, at this time the machine needs to be equipped with two water pumps to complete

At present, the head of the brushless centrifugal water pump will increase attenuation with the motor speed. It is often difficult to increase the head when the head of the pump of the same model (fixed size of magnetic steel and silicon steel sheet) reaches the critical point. In order to increase the head, it is often selected to be larger The pump body or use two pumps of the same type in series to meet the lift required by the customer, but this method greatly increases the product volume and cost
