Description

Technical Field

[0001] The present invention relates to the technical field of axial flow pumps, and more specifically to an energy-saving and environment-friendly axial flow pump. Background Art

[0002] Axial flow pump is a fluid conveying equipment with high efficiency, low energy consumption and environmental protection characteristics. Axial flow pump is a centrifugal pump that guides the fluid to flow in the impeller and closed sliding tube through axial flow. In the axial flow pump, the fluid flows along the axial direction without obvious centrifugal force. This pump is suitable for conveying large flow, low head clean water or liquids with physical and chemical properties similar to clean water. The axial flow pump mainly relies on the force exerted by the blades of the rotating impeller on the liquid to transport the liquid along the axial direction. When the pump shaft is driven to rotate by the motor, due to the certain helix angle between the blades and the axis of the pump shaft, thrust is generated on the liquid, pushing the liquid out and discharging it along the discharge pipe. When the liquid is pushed out, a local vacuum is formed at the original position. Under the action of atmospheric pressure, the liquid outside will be sucked into the impeller along the inlet pipe. As long as the impeller keeps rotating, the pump can continuously inhale and discharge the liquid. The axial flow pump adopts advanced fluid dynamics design and manufacturing technology, and has the characteristics of high efficiency and low energy consumption. When conveying the same flow of liquid, the electric energy consumed by the axial flow pump is much lower than that of other types of pumps. The axial flow pump also has environmental protection function. To ensure performance, when conveying clean water or liquids with physical and chemical properties similar to clean water, no pollution or harmful substances will be discharged. In addition, the structural design of the axial flow pump is reasonable, which reduces the impact of noise and vibration on the environment. The structure of the axial flow pump is relatively simple, consisting of parts such as the water inlet bell mouth, impeller components, impeller housing and guide vane body. This simple structure makes the axial flow pump easy to install, maintain and maintain. The axial flow pump uses a fully sealed dry asynchronous motor as the driving source, which has the characteristics of stable operation and high reliability. At the same time, the axial flow pump is also equipped with monitoring, alarm and protection devices such as seal leakage, coil and shaft temperature rise to ensure that the equipment can be discovered and handled in time when abnormal conditions occur. However, the axial flow pump is prone to scale formation on the inner wall after long-term work, reducing the water capacity of the pump body. When there is no water in the area where the axial flow pump is located, the axial flow pump will still run, and the excess power consumption and empty machine operation will cause damage to the pump body. In addition, the motor of the axial flow pump needs to take appropriate sealing measures to prevent water from entering the motor, which will cause the heat in the motor to be unable to dissipate in time, and the motor is easily damaged in a high temperature environment for a long time.

[0027] The working principle of the present invention is as follows: the axial flow pump is placed underwater, powered on and the switch is turned on to start working, the engine 212 drives the impeller rod 101 to rotate at high speed, the bottom end of the impeller rod 101 is connected to the rotating head 107, the rotating head 107 rotates at high speed with the impeller rod 101, and the water generates a spiral centrifugal force driven by the rotation of the impeller blades 108 to rotate upward, and the vortex water flow rushes to the scale rotary brush 106. Under the action of the thrust of the water flow, the scale rotary brush 106 starts to rotate, and then the brush wheel hollow tube 102 rotates, and the brush wheel hollow tube 102 is connected to the hollow tube 202, and the hollow tube 202 rotates. Similarly, the starting gear 204 starts to rotate, and the starting gear 204 meshes with the linkage gear 205, that is, it drives the linkage gear 205 to rotate, and the cooling fan is connected above the linkage gear 205. 214, the cooling fan 214 rotates and fans the air to be blown into the engine 212 through the outer blowing pipe 215, and the vortex water column in the pump drives the fan blades to rotate to generate flowing wind to dissipate the heat of the engine 212, thereby avoiding the damage to the parts of the engine 212 caused by the high temperature generated by the motor in the closed environment that cannot be dissipated in time. The axial flow pump will form scale at the bottom of the middle circular shell 401 after long-term use. The longer the time, the more scale accumulates. When the scale accumulates to a certain thickness, the cross-section inside the middle circular shell 401 tube is reduced, the circulating water pressure becomes larger, the flow rate of the water flow becomes faster, and the scale brush 106 also becomes faster. At the same time, the impact force of the water flow will squeeze and push the air piston 211 upward, and the air piston 211 squeezes the air in the air storage cone 208, and the air passes through the air The flow bend pipe 207 enters the sealing disk 206 and then enters the connecting air pipe 202 to be transmitted to the rotating shaft 1061, and is dispersed into the air push pipe 1065 to squeeze the connecting brush rod 1066 outward, and the rigid brush 1068 contacts the scale. As the rotating shaft 1061 rotates, the scale is brushed off. When the scale is cleaned, the cross-sectional area of ​​the inner wall of the middle circular shell 401 becomes larger, the water flow speed becomes smaller, and the impact force of the water flow is not enough to push the air piston 211. The air piston 211 is reset under the action of the reed sheet 210, and the air in the brush wheel hollow tube 102 flows back to the connecting air pipe 202. Finally, the root strip 1067 and the rigid brush 1068 are reset back to the rotary blade shell 1063. This process changes the water pressure through the accumulation of scale and finally controls the brush of the telescopic rod by squeezing the air. To achieve the purpose of cleaning the scale on the inner wall of the middle circular shell 401, when the axial flow pump is working, the impeller blades 108 rotate water into the middle circular shell 401, and the water column swirls to impact the scale brush 106, so that the scale brush 106 rotates, drives the brush wheel hollow tube 102 to rotate, and then rotates the hollow tube 202. The rotation of the hollow tube 202 generates current through the power generation device 201. The power generation device 201 is connected to the electro-generated magnetic column 301. The current causes the electro-generated magnetic column 301 to generate a magnetic field. The direction of the magnetic field is opposite to the direction of the magnetic field generated by the reverse magnet block 303. The two repel each other. The reverse magnet block 303 is displaced upward under the action of the magnetic force, and the electric thin rod 304 also moves upward. The copper bar 310 is connected to the electric thin rod 304, and the copper bar 310 moves upward and contacts the live wire 312.The unresistance conductor 309 is a conductor without resistance, which directly short-circuits the fixed resistor 311. The resistance in the series circuit is reduced, the current increases, the speed of the engine 212 increases, the speed of the rotating head 107 also increases, and the water flow extracted also becomes faster. Therefore, the current generated in the power generation device 201 increases, and the magnetic force generated by the magnetic field of the electromagnet 301 increases, pushing the reverse magnet block 303 further upward, so that the resistance push rod 306 pushes the fixed resistor 311 away from the electric wire 312. When the water source extracted by the axial flow pump has no water, the scale brush 106 stops rotating, the power generation device 201 no longer generates current, the magnetic field of the electromagnet 301 disappears, and the reverse magnet block 303 is reset under the action of the reset spring 308, so that the series circuit is short-circuited, the engine 212 stops, and the axial flow pump stops running, avoiding damage to the pump body caused by the axial flow pump running empty.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
