Description

field

[0001] The present invention relates to a water pump for pressurizing water or pumping water to a high level. background

[0002] Existing water pumps are driven by a motor. The high-speed rotation of the pump's blades creates negative pressure, drawing water into the spaces between the blades. Furthermore, the water entering this space is squeezed by the high-speed rotation, causing it to fly outward under centrifugal force, creating pressure. During this process, water entering the negative pressure zone is pushed back by the rotating blades, resulting in low efficiency. Furthermore, when the blades rotate extremely fast, although the negative pressure increases, the speed of the blade pushes against the water, preventing much water from entering the negative pressure zone. Consequently, when the pump pressure remains constant, increasing the power does not increase the pressure. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a water pump with high working efficiency and capable of generating high-pressure water.

[0004] To address the above issues, the present invention operates as follows: water enters a rotating hollow main pipe and flows into a booster pipe connected to and communicating with the main pipe. Centrifugal force exerts pressure on the water in the main pipe and booster pipe, causing it to simultaneously fly out of the booster pipe's outlet, into the area enclosed by the left and right halves and the retaining ring, and then out of that area. During this process, the water enters the main pipe, booster pipe, and the area enclosed by the left and right halves and the retaining ring until it flows out of that area; the water's flow is unimpeded by any components. Based on the above working principle, the technical solution is as follows: the motor is connected to the main pipe by a coupler, the main pipe is supported by a shaft coupling and bearing assembly, the booster pipe is connected to the main pipe, the left and right halves are connected, the bracket is connected to the left half, and the bracket is fixed to the main base. The motor is connected to the main base by the motor bracket. When the motor rotates, it drives the coupler, main pipe, and booster pipe to rotate. Water entering the main pipe and booster pipe also rotates at high speed under the influence of the main pipe and booster pipe. Under the influence of centrifugal force, it flies out along the booster pipe port and then flows out through the hole in the right half. In this process, the water overcomes the impediment of the water flow caused by the high-speed rotation of the blades in existing products. Without any obstruction, the water pressure can increase with the increase of the main pipe and booster pipe speed.

[0005] After adopting the above method, the working efficiency of the water pump is greatly improved, and at the same time, the pressure of the pumped water is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In the attached Figure 1 To the attached Figure 2In the first embodiment shown, the internal inlet unobstructed water pump of the present invention comprises a power part (1), a main pipe part (2), a shell part (3) and a base (4); the power part (1) comprises a motor (1-1), a connector (1-2), a bolt (1-3) and a nut (1-4); the main pipe part (2) comprises a main pipe (2-1), a force pipe (2-2), a fixing ring (2-3), a bearing seat assembly (2-4), a bolt (2-5), a shaft end nut (2-6) and a cotter pin (2-7); the shell part (3) comprises a bracket (3-1), a left half (3-2), a right half (3-3), a water outlet pipe body (3-4), a sealing ring (3-5), a sealing strip (3-6), a bolt (3-7) and a nut (3-8); and the base (4) comprises a main base (4-1), a motor frame (4-2) and a secondary bracket (4-3). The motor (1-1) is mounted on the motor bracket (4-2) by bolts (1-3) and nuts (1-4); the bearing seat assembly (2-4) is mounted on the auxiliary bracket (4-3) by bolts (2-5); the booster pipe (2-2) is welded to the main pipe (2-1); and a hole drilled on the main pipe (2-1) is communicated with the booster pipe (2-2). The fixing ring (2-3) is welded on the booster tube (2-2), the sealing strip (3-6) is stuck in the groove of the fixing ring (2-3), the bracket (3-1) is installed on the main seat (4-1) by bolts (3-7), and the left half (3-2) is welded on the bracket (3-1); the main tube (2-1) is a hollow tube with no passage near the left end; the left half (3-2) and the right half (3-3) are sleeved on the main tube (2-1), the sealing ring (3-5) is stuck in the grooves opened by the left half (3-2) and the right half (3-3), and the bearing seat assembly (2 -4) on the main pipe (2-1), and then the shaft end nut (2-6) and the split pin (2-7) are installed; the connector (1-2) connects the motor (1-1) and the main pipe (2-1); the motor bracket (4-2) and the auxiliary bracket (4-3) are welded to the main seat (4-1); the water outlet pipe body (3-4) is welded to the right half (3-3), and the right half (3-2) and the right half (3-3) are connected by bolts (3-7) and nuts (3-8). The hole opened in the right half (3-3) is connected to the water outlet pipe body (3-4). Water enters from the hole at the end of the main pipe (2-1). During the specific operation, water is first introduced into the main pipe (2-1), and the motor (1-1) is powered on. After the motor (1-1) rotates, the main pipe (2-1) and the boosting pipe (2-2) are driven to rotate via the connector (1-2). The water in the main pipe (2-1) and the boosting pipe (2-2) is centrifugally forced to flow out of the port of the boosting pipe (2-2), thereby generating pressure. The water then flows from the space enclosed by the left half (3-2) and the right half (3-3) to the outlet of the water outlet pipe (3-4). As can be seen from the above, during the entire pressurization process, no parts hinder the flow of water. Therefore, the pressure of the water increases with the increase of the motor speed.This overcomes the problem in existing products where the water entering is always hindered by the rotating blades; when the blade speed reaches a certain amount, it accelerates again while the water pressure increases very little, causing the pressure of the water pump to increase significantly.

[0012] In the attached Figure 1 To the attached Figure 3 In the second embodiment shown, the internal inlet unobstructed water pump of the present invention differs from the first embodiment in that two booster pipes (2-2) are installed radially on the main pipe (2-1), thereby increasing the amount of water pumped.

[0013] In the attached Figure 1 To the attached Figure 2 , and attached Figure 4 In the third embodiment shown, the difference from the first embodiment is that the front end of the booster tube (2-2) is tapered, so that the centrifugal force is increased and the amount of water sucked in is increased.

[0014] In the attached Figure 1 To the attached Figure 2 , and attached Figure 5 The fourth embodiment shown differs from the first embodiment in that a rear pipe assembly (2-7) is added to the main pipe portion (2), and a rear seat (4-4) is added to the base (4). The rear pipe assembly (2-7) includes a fixed pipe (2-7-1), a sealing ring (2-7-2), a sealing ring (2-7-3), a bolt (2-7-4), and a nut (2-7-5). The rear seat (4-4) is welded to the main seat (4-1), and the sealing ring (2-7-2) and the sealing ring (2-7-3) are installed in the groove of the fixed pipe (2-7-1). The fixed pipe (2-7-1) is installed on the rear seat (4-4) by bolts (2-7-4) and nuts (2-7-5). In this way, the water pipe from the outside can be directly connected to the fixed pipe (2-7-1).

[0015] The present invention is not limited to the above forms. When there is no booster pipe (2-2) and fixed ring (2-3); when a valve is added between the water outlet pipe body (3-4) and the right half (3-3); when there is no connector (1-2) and the motor (1-1) is directly connected to the main pipe (2-1); when it is not used for pumping water but for pumping other liquids, air (other gases) or mixtures; when the main pipe (21-) is driven by other power; when the main pipe (2-1) is rotated by other means; and when the above forms are combined to form new forms, all of these are the contents of the present invention.
