Baffle type water pump

Abstract

The invention discloses a baffle type water pump which comprises a motor blade (2), a nut (3), a key (4) and a baffle (5). The key (4) is placed in a key groove of an output shaft of the motor (1), the blade (2) is arranged on the output shaft of the motor (1) in a sleeved mode, and the nut (3) is arranged on the output shaft of the motor (1) and tightly presses the blade (2). And the baffle (5) is welded on the blade (2) close to a high-pressure water area. During use, the motor (1) is started and drives the blade (2) to rotate, the positive pressure area surface of the blade (2) pushes front water into high-pressure water, meanwhile, the baffle (5) is additionally arranged, and the back surface of the blade (2) and the baffle (5) form a negative pressure space, so that the negative suction force to a low pressure area is greatly increased, the sucked low-pressure water is greatly increased, the working efficiency is improved, and the working cost is reduced.

Description

[0001] 1. Field:

[0002] The present invention relates to a water pump for increasing the pressure of water.

[0003] 2. Background:

[0004] In the existing water pump, the motor drives the blades to rotate. Since the blades are installed at an angle, positive water pressure is generated on one side of the blades, while negative pressure is generated in the background. The positive pressure surface generates water pressure, while the negative pressure surface absorbs low-pressure water to the negative pressure surface. The sucked-up low-pressure water is pressurized by the rotation of the blades and flows toward the high-pressure water; thus, high-pressure water is continuously generated. During this working process, when the negative pressure surface absorbs low-pressure water to the negative pressure surface, the high-pressure water in the high-pressure water area is also sucked into the negative pressure surface, resulting in a reduction in the suction of low-pressure water, which reduces work efficiency and increases work costs. 3. Summary of the invention:

[0005] The problem to be solved by the present invention is to increase the working efficiency of a water pump and reduce the working cost by adopting a new method.

[0006] In order to solve the above problems, the working principle of the present invention is to add a baffle near the high-pressure water area of ​​the blade, so that the low-pressure water flowing into the negative pressure area will increase significantly, while the high-pressure water flowing into the negative pressure area will not increase.

[0007] After adopting the above method, when the water pump is working, the low-pressure water sucked in increases significantly, the working efficiency is improved, and the working cost of the water pump is reduced. 4. Description of the drawings:

[0009] Attached Figure 2 This is a partial structural diagram of the first embodiment of a baffle type water pump of the present invention. V. Summary of the invention:

[0011] In the attached Figure 1 To Attachment Figure 2In the first embodiment shown, a baffle type water pump of the present invention comprises a motor (1), a blade (2), a nut (3), a key (4) and a baffle (5); the key (4) is placed in the keyway of the output shaft of the motor (1), the blade (2) is sleeved on the output shaft of the motor (1), the nut (3) is on the output shaft of the motor (1), and the blade (2) is pressed; the baffle (5) is welded to the position of the blade (2) near the high pressure water area. When in use, the motor (1) is started, the motor (1) drives the blade (2) to rotate, and the positive pressure area surface of the blade (2) pushes the water in front into the high pressure water. At the same time, due to the addition of the baffle (5), the back of the blade (2) and the baffle (5) form a negative pressure space, which greatly increases the negative suction force on the low pressure area, and the amount of low pressure water sucked in greatly increases, so the work efficiency is increased and the work cost is reduced.
