The whole structure is simple, the principle is reliable, the mechanical operation stability is good, the abrasion resistance is good, and the stirring effect is good.
The water pump is provided with helical blades with the corresponding screw pitches according to different models.
The pitch of the helical blade of the screw feeder 6 was 30 mm. The helical blade of the screw feeder 6 has a helix angle of 720 °. The coordination of the wheel thread pitch and the spiral angle can effectively drive the media around the water inlet 5 to rapidly enter the spiral centrifugal impeller 3, ensure that the media have enough driving force, avoid the media from reversely flowing out and effectively avoid the occurrence of blockage.
The screw feeder 6 is fully immersed inside the medium when in use. The spiral thrust can be transmitted to the medium, so that the flow thrust forced to enter is provided for the medium, and the medium can enter the flow channel quickly and efficiently.
The horizontal outer diameter of the spiral blade of the spiral feeding mechanism 6 is larger than the inner diameter of the water inlet 5. The contact area of the water inlet 5 with the medium is large, the medium at the water inlet 5 can be uniformly distributed, and the propelling flow of the medium is improved.
The spiral centrifugal impeller comprises a centrifugal hub 7 which is coaxially and rotationally connected with the central rotating shaft and impeller blades which are spiral along the hub 7. The connecting seams 9 between the impeller blades and the hub extend along the circumferential surface of the hub 7 and are in spiral line shapes, and the included angle alpha between the connecting seams and the horizontal plane is an acute angle; to increase the output pressure and reduce turbulence.
The centrifugal hub 7 extends from the base part to the free end part to form a conical body structure, and the outer side wall of the conical body is set to be a smooth arc-shaped curve structure so as to reduce the rotating resistance of the spiral centrifugal impeller and prolong the service life of the device; the impeller blades extend spirally from the base part to the free end part to form a structure with a wide base part and a narrow free end part, and the cross section of each impeller blade is in a willow-leaf shape, so that the problem of secondary backflow caused by the fact that the flow velocity of a medium at the end part is relatively high and the outlet pressure is inconsistent is solved, and the efficiency is improved.
The outside of motor sets up heat exchanger 2, and the top of heat exchanger 2 is provided with handle 1, and heat exchanger 2 sets up to cavity round platform body tubular structure, and the lateral wall of heat exchanger 2 sets up the louvre along circumference equipartition. The heat dissipation cover 2 is used for cooling the motor, the heat dissipation holes can increase the contact area with the outside,
the specific operation process is as follows:
(1) installing a spiral centrifugal impeller 3 and a spiral feeding mechanism: firstly, an impeller is installed together with a central rotating shaft of a spiral feeding mechanism through a hub 7, and then the central rotating shaft is installed together with a submersible motor with matched power to share one shaft;
(2) starting a motor: then the submersible motor is powered on, and the motor drives the hub 7, the spiral centrifugal impeller 3 and the spiral feeding mechanism to rotate together;
(3) water inlet and outlet of the blades: the spiral blade of the spiral feeding mechanism rotates to supply certain driving force to media around the water inlet 5, the media contacted with the spiral blade flows inwards along the axial direction of a spiral flow channel (formed by the arc-shaped curved surface of the spiral blade) due to pressure, the driving media are quickly pushed to the water inlet 5, and then the media flow outwards along the water outlet 4 under the action of the driving force of the impeller blade 8 of the spiral centrifugal impeller 3; the spiral blade of the spiral feeding mechanism supplies the forced driving force of the liquid medium at the water inlet 5, so that the good fluidity of the medium is ensured.
