The motor 02 and the speed reducer 03 are both arranged on the base 01. One end of the output shaft 21 of the motor 02 is provided in the decelerator 03. The water inlet pipe shaft 04 passes through the speed reducer 03 and then is arranged in the shell 06. The water inlet pipe shaft 04 is connected with the output shaft 21 of the motor 02 in a transmission way. An inner housing 61 is provided in the housing 06, and the inner housing 61 divides a space in the housing 06 into an outer cavity 62 and an inner cavity 63. The impellers 05 are located in the inner cavity 63 and the impellers 05 are spaced circumferentially about the inlet pipe axis 04. The inner housing 61 is provided with spray nozzles 611 at intervals. The drainage plates 07 are located in the outer cavity 62 and are arranged on the inner housing 61 at intervals along the circumferential direction of the inlet pipe shaft 04. The end of the flow-guiding plate 07 remote from the inner casing 61 is curved in the direction in which the impeller 05 rotates. The space between the flow guiding plate 07 and the housing 06 forms a flow rotation path. The water inlet channel 41 of the water inlet pipe shaft 04 is spiral. A water inlet 42 is provided at a distance from the end of the inlet pipe shaft 04 located in the inner cavity 63. A water outlet 64 is arranged on one side of the shell 06 close to the base 01. The water outlet 64 is connected with the water outlet pipe 08.
The water inlet channel 41 of the water inlet pipe shaft 04 is spirally arranged to enable water flow to rotate in the pipeline, and the water flow is discharged from the water inlet 42 by utilizing the rotating motion when reaching the inner cavity 63, so that the power of the water flow is fully utilized, the initial power with the same direction is provided for the motion of the water flow in the inner cavity 63, the energy loss required by the impeller 05 for initially pushing the water flow is reduced, the energy is saved to a certain extent, and the centrifugal effect is improved because the direction is consistent with the direction of the rotating and swinging water body of the impeller 05. Meanwhile, the drainage plate 07 with the bending amplitude consistent with the water body movement direction is arranged in the outer cavity 62 to serve as drainage, so that the kinetic energy generated by the water body can be fully utilized, the water body is ensured not to generate energy loss due to the fact that the water body is thrown out and then is impacted on the shell 06, a drainage path is formed to drain the water body, the energy consumption is reduced to a certain extent, the drainage power and flow of the water pump are improved, and a good energy-saving and efficiency-increasing effect is achieved.
The specific structure of each part is described in detail below:
The motor 02 is in transmission connection with the water inlet pipe shaft 04 through the speed reducer 03, and the connection modes are various, and can be gear connection, turbine worm connection, coupling connection and the like, in the embodiment, the output shaft 21 of the motor 02 is connected with the water inlet pipe shaft 04 through gear transmission in the speed reducer 03, so that the transmission power can be ensured, and the water body can be ensured to flow in the water inlet channel 41 without loss by reducing vibration as far as possible due to the water flow passing through the water inlet pipe shaft 04.
The water flow enters the inner cavity 63 from the water inlet pipe shaft 04 for rotation and centrifugation, and because the axial direction of the water inlet pipe shaft 04 is vertical to the rotating plane of the impeller 05, the water body needs to change the moving direction when the water inlet pipe shaft 04 is discharged, in order to avoid loss as much as possible, the water inlet channel 41 in the water inlet pipe shaft 04 can be arranged into a spiral shape, thus the water flow rotates in the water inlet pipe shaft 04, can be thrown out by the centrifugal force generated by the rotation of the water flow when the water flow reaches the water inlet 42, further changes the moving direction, obtains initial kinetic energy when the water flow is discharged from the water inlet 42, does not need to be directly pushed by the impeller 05 to generate initial movement, reduces the loss driven by the impeller 05 to a certain extent, and achieves the effects of energy conservation and synergy.
It will be appreciated that if the flow rate of the water flow in the water inlet pipe shaft 04 is too large, the excessive water flow will return to form turbulence after striking the end of the water inlet pipe shaft 04, so as to disturb the movement of the water flow, not only prevent the water flow from exiting the water inlet 42, but also increase the energy consumption of the impeller 05 to push the water body without initial kinetic energy to move, therefore, in this embodiment, the maximum flow rate of the water inlet channel 41 does not exceed the total drainage amount of the water inlet 42.
Thus, since the maximum inlet flow of the water inlet channel 41 does not exceed the total drainage amount of all the water inlets 42, when water enters one end of the water inlet pipe shaft 04 positioned in the inner cavity 63, the water can be completely discharged before the end is impacted, no energy loss is generated, the effect of fully utilizing the kinetic energy of the water body is achieved, the impact on the water inlet pipe shaft 04 is reduced, the service life of the water inlet pipe shaft 04 is prolonged to a certain extent, and the service life of the water pump is further prolonged to a certain extent.
In addition, the arrangement of the water inlets 42 also affects the initial kinetic energy of the water after being discharged and the energy consumption of the impeller 05. In this embodiment, the arrangement path of the water inlets 42 in the axial direction of the water inlet pipe shaft 04 is the same as the direction of the impeller 05.
Like this, the water inlet 42 along the arrangement mode of intake pipe axle 04 axis direction with impeller 05 trend unanimous, the speed of water when the water is discharged water inlet 42 and the lateral wall parallel of impeller 05 can be guaranteed, can not produce the loss to the initial kinetic energy of water like this to also can not make impeller 05 need consume extra kinetic energy to offset this part atress because of the inconsistent striking of direction on impeller 05, reduced the energy loss of impeller 05 to a certain extent, the energy has been practiced thrift. In addition, since the water body has initial power, the water body can rapidly leave the vicinity of the water inlet pipe shaft 04 after being discharged from the water inlet 42, negative pressure can be well generated in the vicinity of the water inlet pipe shaft 04, continuous pressure difference energy is provided for the subsequent water body discharge, the continuity of water pump operation is ensured, and a good pressurizing and draining effect is achieved.
The water body is driven by the impeller 05, flies out along the radial direction of the rotation of the impeller 05 under the action of centrifugal force, is discharged into the outer cavity 62 through the jet flow port 611, and is discharged along the outer cavity 62 with a water outlet. The drainage plate 07 is positioned near the spray port 611, and the bending direction is consistent with the movement direction of the outer cavity 62 into which the water body enters. The flow guiding plate 07 can fully guide and convert the kinetic energy of the water body along the radial direction into the circumferential motion around the shell 06, so that the kinetic energy of the water body is not damaged, the outlet flow velocity of the water body is increased, and the effects of energy conservation and synergy are achieved to a certain extent.
Of course, since one end of the flow guiding plate 07 is to be connected with the inner shell 61, the connection portion will obstruct the movement of the water body and generate partial choked flow nearby, so the number of the flow guiding plates 07 will also have a certain influence on the kinetic energy of the water body, too little flow guiding plate 07 will not achieve the effect of flow guiding, and too much choked flow will be generated. In this embodiment, the number of the flow guiding plates 07 is the same as the number of the impellers 05.
Like this, the quantity of flow guiding plate 07 keeps unanimous with impeller 05, and like this, the water that throws away between the impeller 05 can furthest be discharged at each jet port 611 not hindered by flow guiding plate 07 end, furthest reduces the energy loss of water, reaches energy-conserving synergy's effect.
In addition, the end of the drainage plate 07 far from the inner casing 61 is tangent to the inner wall of the casing 06. Thus, the water body can be fully ensured to be directly impacted with the inner wall of the shell 06 to consume energy after being drained by the drainage plate 07, and the whole flow of water flow is not influenced by turbulence caused by direct impact, so that a good energy-saving and efficiency-increasing effect can be achieved.
For the arrangement of the water outlet 64, in this embodiment, the axial direction of the water inlet pipe shaft 04 is perpendicular to the rotation plane of the impeller 05; the water outlet direction of the water outlet 64 is tangential to the cylindrical surface formed by the rotation of the water flow in the outer cavity 62. The direction of the water outlet 64 is tangential to the rotation direction of the water flow, so that the water flow can not be blocked to consume energy when entering the water outlet pipe 08, and the water flow resistance at the water outlet 64 can not be generated due to the blocking of the water flow, the water body discharge is affected, the energy consumption is reduced to a certain extent, and the efficiency of the water pump is improved.
The specific implementation manner of this embodiment is as follows:
The water body enters from the water inlet pipe shaft 04, rotates along with the spiral channel of the water inlet pipe shaft 04, enters into the inner cavity 63 from the water inlet 42 by the centrifugal force generated by rotation, is thrown to the periphery by the driving of the impeller 05, enters into the outer cavity 62 by the jet flow port 611 and the drainage plate 07, and finally moves along the circumferential direction of the inner wall of the shell 06 and is discharged by the water outlet.
In addition, since the water flow acts on the surface of the device for a long time, on the one hand, the fluid has a viscous effect, friction is generated between the fluid and the surface of the device having affinity, and the water flow also corrodes the device for a long time, in this embodiment, a polymer ceramic coating is coated on the inner wall of the water inlet channel 41, the outer surface of the inner end of the water inlet pipe shaft 04 located in the 06 housing, the surface of the impeller 05, the inner wall of the housing 06, the surface of the inner housing 61, and the inner wall of the water outlet pipe 08. Therefore, the surface of the equipment through which water flows is coated with the polymer ceramic coating to form a hydrophobic and corrosion-resistant surface, so that the friction force between the water flow and the surface of the equipment is reduced, the loss of mechanical energy and hydraulic power of the water pump is avoided, and the condition that the space occupied by corrosion of the surface of the equipment is also placed, and the volume of the water pump is reduced. Of course, in order to further reduce the cost while ensuring the complete efficacy of the polymeric ceramic coating, the polymeric ceramic coating has a thickness of 0.38mm to 0.5mm.
The described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
