DETAILED DESCRIPTION
[0028] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.
[0029] It should be noted that the embodiments and features in the embodiments can be combined with each other without conflict.
[0030] The present application provides an integrated pump station and a series type conveying system comprising the integrated pump station. The series type conveying system comprising multiple pump stations can gradually increase the pressure to overcome the high lift or long distance conveying requirements that a single pump cannot achieve, and the application fields include urban water supply, mine drainage, agricultural irrigation, etc.
[0031] Reference Figures 1-4 The embodiment of the present application provides an integrated pump station, which comprises a water pump 10 and a container 20, and the pump body 11 of the water pump 10 is assembled into the water cavity 21 and combined with the container 20. The container 20 constitutes a relay water storage facility to replace the traditional water pool and other facilities.
[0032] Reference Figure 2The water pump 10 includes a pump body 11, a rotor structure 12, and a drive source 13. The pump body 11 has an internal space 111, a water pump inlet 112, and a water pump outlet 113. The rotor structure 12 includes a pump shaft 121 and an impeller 122. The pump shaft 121 passes through the internal space 111 of the pump body 11, and the impeller 122 is mounted on the pump shaft 121. The drive source 13 is poweredly connected to one end of the pump shaft 121 to drive the rotor structure 12 to rotate.
[0033] It should be noted that the rotor structure 12 is the rotating part within the pump body 10, including the pump shaft 121, impeller 122, and other components that rotate with the pump shaft. Multiple gap seals are provided at different positions on the rotor structure 12 and the pump body 11, utilizing the small gaps between the rotor structure and the pump body for sealing. Multi-stage impellers can be mounted on the pump shaft 121; these impellers can be centrifugal pump impellers or mixed-flow pump impellers. Centrifugal pumps operate by using the rotation of the impeller to cause centrifugal motion of water. Before starting, the pump body and suction pipe are filled with water. Then, the motor is started, causing the pump shaft to drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion, being thrown towards the outer edge of the impeller and flowing into the pump's discharge pipe through the flow channel of the volute casing. During operation, the impeller rotation of a mixed-flow pump exerts both centrifugal force and axial thrust on the liquid. In a specific technical solution, the multi-stage pump is a multi-stage centrifugal pump, and all multi-stage impellers are centrifugal pump impellers. During operation, the liquid being pumped enters the pump body through the inlet. Due to the impeller's action, both the liquid's kinetic and potential energy increase. After entering the guide vanes (each impeller stage is equipped with a guide vane), some of the kinetic energy is converted into potential energy. The guide vanes' counter-rotating blades, under favorable hydraulic characteristics, transport the liquid to the inlet of the next impeller stage. Each stage increases the pressure by the same amount. After passing through the final stage guide vane, the liquid is discharged from the outlet. The water pressure of a multi-stage centrifugal pump is the sum of the pressures from each impeller stage, thus achieving a larger outlet pressure. Figure 2 As shown, a two-stage impeller can be mounted on the pump shaft 121.
[0034] Drive source 13 can be configured as a motor, in Figure 2 In the structure shown, the motor is located above the rotor structure 12. When the output shaft of the motor rotates, the rotor structure 12 rotates synchronously. The impeller 122 on it pressurizes the water flow entering from the water pump inlet 112, and the pressurized water is discharged from the water pump outlet 113.
[0035] The container 20 is provided with a water cavity 21, an external water inlet 22 and an external water outlet 23; the pump body 11 of the water pump 10 is installed in the water cavity 21 and combined with the container 20; the water pump outlet 113 is sealed and connected with the external water outlet 23 from the inside of the water cavity 21 to form a drainage channel; the water pump inlet 112 is exposed in the water cavity 21 and its height position is lower than that of the external water inlet 22.
[0036] In the embodiment of the present application, the series type conveying system is formed by connecting the plurality of integrated pump stations 100 in series. In the series type conveying system, the external water outlet 23 of the upper integrated pump station 100 is connected to the external water inlet 22 of the lower integrated pump station 100 by a pipeline. When the integrated pump station 100 is working, the water flow in the water inlet pipeline enters the water cavity 21 inside the container 20 through the external water inlet 22. Then, the water flow in the water cavity 21 enters the water pump 10 through the water pump water inlet 112 to be pressurized. Finally, the pressurized water flow in the water pump 10 is output through the water pump water outlet 113 on the pump body 11 and the external water outlet 23 of the container 20, and can enter the lower integrated pump station 100. In this way, the water flow is pressurized and conveyed step by step through the plurality of integrated pump stations 100, so that the requirement of high lift or long distance conveying can be met. The above integrated pump station directly combines the pump body of the water pump and the container, omits the traditional water storage facility, is more flexible and convenient in arrangement, and has relatively low cost.
[0037] Figure 6 A series type conveying system formed by connecting a plurality of integrated pump stations 100 in series is shown. The series type conveying system contains at least three integrated pump stations 100. The external water outlet 23 of the first integrated pump station 100 is connected to the external water inlet 22 of the second integrated pump station 100 by a pipeline. The external water outlet 23 of the second integrated pump station 100 is connected to the external water inlet 22 of the third integrated pump station 100 by a pipeline. When the series type conveying system is working, the external water inlet 22 of the first integrated pump station 100 is supplied with water. The water flow is pressurized and conveyed by the first integrated pump station 100 for the first time, by the second integrated pump station 100 for the second time, and by the third integrated pump station 100 for the third time. After the three times of pressurization and conveying, the water flow is output through the external water outlet 23 of the third integrated pump station 100.
[0038] The integrated pump station 100 also has a sensor for sensing the water inlet pressure. The driving source 13 can be linked with the sensor. When the water flow in the water inlet pipeline enters the water cavity through the external water inlet 22, the sensor can sense the water inlet pressure. At this time, in response to the sensor sensing the water inlet pressure, the driving source 13 starts to output power, and the water pump starts to work.
[0039] In an embodiment of the present application, the pump body 11 is detachably assembled on the container 20. When the water pump 10 needs to be overhauled or maintained, the maintenance personnel can detach the pump body 11 from the container 20 to separate the water pump 10 and the container 20, so that the water pump 10 can be conveniently overhauled or maintained.
[0040] Reference Figure 3The bottom of the container 20 is further provided with a drain 26, and a detachable sealing member 27 is arranged on the drain 26. When the container 20 needs to be cleaned due to the deposition of a large amount of silt, the sealing member 27 can be removed by the maintenance personnel, and the silt deposited in the container 20 is cleaned and discharged through the drain 26.

[0044] With reference to Figure 5In an embodiment of the present application, the integrated pump station 100 further comprises a control assembly 30; the control assembly 30 is connected to the container 20 and is elastically mounted by elastic elements. On the one hand, the control assembly 30 is integratedly mounted on the container 20, and the structure is more compact. On the other hand, the elastic elements can buffer the vibration of the control assembly 30, and reduce the influence of the vibration generated by the integrated pump station 100 during operation on the control assembly 30. Here, the elastic elements can be springs.
