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

Embodiment 1

[0023] Such as Figure 1-3 As shown, a water pump with double water outlets includes a first side cover 21, a sealing plate 22, a middle plate 23, a casing 24 and a second side cover 25 arranged in sequence, and the first side cover 21 and the sealing plate 22 form a second A pump chamber 31, a second pump chamber 33 is formed between the second side cover 25 and the casing 24, an installation cavity 32 is formed between the casing 24 and the middle plate 23, and the stator 5, the middle plate 23 and the seal are arranged in the installation cavity 32 A rotor cooperating with the stator 5 is arranged between the plates 22. A main shaft 44 is arranged at the center of the rotor, and the two ends of the main shaft 44 extend toward the first pump chamber 31 and the second pump chamber 33. 31. The second pump chamber 33 is respectively provided with impellers, the first pump chamber 31 is provided with a first impeller 41, the second pump chamber 33 is provided with a second impel...

Embodiment 2

[0035] like figure 1 As shown, the difference from the technical solution of the first embodiment above is that the first water inlet pipe is connected to the second water outlet pipe through a conduit (or the first water outlet pipe is connected to the second water inlet pipe through a conduit) to connect the first pump chamber and the second water outlet pipe. The second pump chamber communicates and forms a pumping passage with a long lift, which improves the lift of the water pump and the flow rate of the pumped liquid.

[0036] After the stator 5 of the present invention is energized, the rotor starts to drive the main shaft 44 to rotate, and the two ends of the main shaft 44 drive the impeller to rotate. When the impeller rotates, a vortex will be formed in the first pump chamber and the second pump chamber to generate pressure, and the liquid will pass through the first water inlet pipe 11 Enter the first pump chamber, and then pump the liquid from the first water outle...

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...
