Description

Technical Field

[0001] This invention relates to the field of water supply pump technology, specifically a water supply pump set system. Background Technology

[0002] Currently, thermal power plants, water supply facilities, and other facilities all require water supply systems, and steam-driven feedwater pump sets are commonly used. A steam-driven feedwater pump set mainly consists of a feedwater pump turbine, a main feedwater pump, a feedwater booster pump, and a gearbox (or hydraulic coupling).

[0003] During water transport, if sand and gravel are mixed in, the continuous accumulation of sand and gravel will eventually clog the water pump. However, the accumulation of sand and gravel takes a long time. As the sand and gravel continue to accumulate, the impeller inside the water pump will eventually become stuck and stop rotating. Because there are many internal components of the water pump, disassembly is troublesome, and manual cleaning is time-consuming and labor-intensive.

[0004] Therefore, a water pump that is regularly tested and processed for fine sand and gravel should be established. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water supply pump system that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water supply pump system comprising multiple pump bodies, a drain pipe, and a main control module. The drain pipe has multiple branches on its left side, each branch connecting to a pump body. The main control module is located on the right side of the drain pipe. A motor is located on the top of the pump body, and a cavity is formed inside the pump body. The motor drive shaft extends vertically into the cavity and is connected to an impeller. An inlet pipe is connected to the left side of the pump body, and the outlet end of the inlet pipe communicates with the bottom of the cavity. A drain channel is formed on the right side of the pump body, and the side of the pump body is connected to the drain channel.

[0007] It also includes a paddle and an electric actuator. The inner wall of the cavity has multiple grooves. The upper end of the paddle is hinged to the inner wall of the groove. The pump body has multiple slots, which correspond one-to-one with the grooves. The electric actuator is placed in the slot. The movable end of the electric actuator passes through the slot and is hinged to the paddle.

[0008] When the electric actuator is extended to its maximum length, the lever flips upward at a certain angle, and the lever will never touch the impeller.

[0009] The bottom of the inner wall of the cavity is provided with a bottom groove, which is arranged in a circle. An annular elastic film is provided at the opening of the bottom groove. Multiple push switches are arranged at equal angles at the bottom of the inner wall of the bottom groove. A data receiving module is provided on the outside of the pump body. The electric push rod, the data receiving module and the main control module are electrically connected.

[0010] The inlet pipe is equipped with a speed reduction module, which slows down the water flow at regular intervals to detect the content of fine sand and gravel in the cavity. When the water flow is slowed down, the fine sand and gravel settle and accumulate on the elastic membrane. The elastic membrane sinks and presses down the switch. The data receiving module receives the signal and feeds it back to the main control module. The main control module transmits the feedback information to the computer terminal.

[0011] Preferably, the deceleration module includes a flap, a spring, and a second electric actuator. A receiving cavity is provided inside the pump body and above the water inlet pipe. The receiving cavity is connected to the inside of the water inlet pipe. An elastic membrane is provided at the opening of the receiving cavity. The upper end of the flap is hinged to the inner wall of the receiving cavity. The lower end of the spring is in contact with the elastic membrane. The side of the flap away from the elastic membrane is connected to the spring. The end of the spring away from the flap is connected to the top of the inner wall of the receiving cavity. The second electric actuator is placed on the top of the inner wall of the receiving cavity and is perpendicular to the flap.

[0012] The extension of the electric actuator causes the flap to deflect downwards, causing the elastic membrane to bulge towards the inside of the water inlet pipe. The bulging of the elastic membrane forms a gentle slope, reducing the amount of water entering the water inlet pipe.

[0013] When the elastic membrane bulges to its maximum, its cross-sectional width is half the inner diameter of the inlet pipe.

[0014] Preferably, it also includes an elastic film, the edge of which is connected to the inner wall of the cavity, and the elastic film covers the groove.

[0015] Preferably, the bottom of the inner wall of the water inlet pipe is threaded with a bottom cover.

[0016] Preferably, a sealing block is threadedly connected to the top of the pump body and directly above the cavity, a bracket is connected to the top of the sealing block, the top of the bracket is connected to the motor, and the motor drive shaft vertically passes through the sealing block.

[0017] Preferably, a connecting pipe is provided on the side of the cavity, and the end of the connecting pipe away from the cavity is connected to the drainage channel.

[0018] This invention provides a water supply pump set system. It has the following beneficial effects: 1. This water supply pump system comprises a pump body, a motor, an impeller, and a drain pipe. Adjusting the motor speed above the pump reduces the water flow velocity entering the pump body, facilitating the deposition of fine sand and gravel on the inner wall of the cavity. The accumulation of fine sand and gravel causes the elastic diaphragm to indent and contact a pressure switch, transmitting information to the main control module. The main control module then operates a flap to sweep away the deposited fine sand and gravel.

[0019] 2. This water supply pump system includes a receiving cavity located within the pump body and at the top of the inlet pipe. The receiving cavity is connected to the inlet pipe and contains a flap, a spring, and an electric actuator. The electric actuator rotates the flap, causing the elastic diaphragm to bulge, reducing the water flow into the inlet pipe. The bulging elastic diaphragm acts as a buffer, achieving a secondary speed reduction. This facilitates subsequent inspection and cleaning.

[0020] 3. This water supply pump system allows for individual control of each pump via a central control module. Each pump is inspected sequentially. While one pump is being inspected and cleaned, the central control module adjusts the motor speeds of the remaining pumps, ensuring the overall water supply power of the system remains unaffected. This prevents a decrease in the system's efficiency due to pump maintenance. Attached Figure Description

[0023] This invention provides a water supply pump system, such as... Figure 1-7As shown, the system includes multiple pump bodies 1, drain pipes 3, and a main control module 8. Multiple branches are welded to the left side of the drain pipes 3, each branch being fixedly connected to a pump body 1. The main control module 8 is fixedly installed on the right side of the drain pipes 3. A motor 2 is fixedly installed on the top of each pump body 1. A cavity 11 is opened inside each pump body 1, and the drive shaft of the motor 2 extends vertically into the cavity 11, where an impeller 21 is fixedly installed. The pump bodies 1 and drain pipes 3 form a water pump assembly. The main control module 8 is used to control the operation of each electronic component. Each pump body 1 is connected to an external power supply wire.

[0024] A water inlet pipe 12 is welded to the left side of the pump body 1. The water outlet end of the water inlet pipe 12 is connected to the bottom of the cavity 11. A drainage channel 13 is opened on the right side of the pump body 1. The side of the pump body 1 is connected to the drainage channel 13.

[0025] It also includes a paddle 5 and an electric actuator 51. The inner wall of the cavity 11 has multiple grooves 111. The upper end of the paddle 5 is hinged to the inner wall of the groove 111. The pump body 1 has multiple slots 15. The slots 15 correspond one-to-one with the grooves 111. The electric actuator 51 is fixedly installed in the slot 15. The movable end of the electric actuator 51 passes through the slot 15 and is hinged to the paddle 5.

[0026] When the electric actuator 51 is extended to its longest length, the paddle 5 rotates upward 45°, and the paddle 5 will never touch the impeller 21.

[0027] A bottom groove 112 is provided at the bottom of the inner wall of the cavity 11. The bottom groove 112 is arranged in a ring. An annular elastic membrane 113 is fixedly installed at the opening of the bottom groove 112. Multiple push switches 114 are arranged at equal angles at the bottom of the inner wall of the bottom groove 112.

[0028] A data receiving module is also fixedly installed on the outside of the pump body 1. The electric actuator 51, the data receiving module and the main control module 8 are electrically connected.

[0029] The inlet pipe 12 is equipped with a speed reduction module, which slows down the water flow at regular intervals to detect the content of fine sand and gravel in the cavity 11.

[0030] The aforementioned elastic membrane 113 is originally flush with the bottom of the inner wall of cavity 11. When the weight of the fine sand and gravel accumulated on the elastic membrane 113 is sufficient, it will slightly indent and come into contact with the push switch 114.

[0031] During operation, multiple pump bodies 1 are tested sequentially one by one. When a single pump body 1 is tested, the speed of its motor 2 decreases to reduce the water flow rate. However, to avoid affecting the overall water delivery power of the water pump system, the speed of the motor 2 of the remaining pump bodies 1 increases.

[0032] Detection and cleaning process: The water flow in the inlet pipe 12 is reduced a second time through the speed reduction module. The reduced water flow speed weakens the impact force of the water flow, making it easier for fine sand and gravel to settle at the bottom of the inner wall of the cavity 11, and some fine sand and gravel accumulates above the elastic membrane 113.

[0033] When there is enough fine sand and gravel, the weight of the fine sand and gravel causes the elastic membrane 113 to sink. The sinking elastic membrane 113 presses down the push switch 114. The data receiving module receives the signal and feeds it back to the main control module 8. The main control module 8 transmits the feedback information to the computer terminal.

[0034] The electric actuator 51 is extended by the main control module. The electric actuator 51 drives the paddle 5 to tilt up, sweeping the fine sand and gravel accumulated at the bottom of the inner wall of the cavity 11 into the water inlet pipe 12. As shown in the attached diagram, the water inlet pipe 12 is arc-shaped.

[0035] The bottom of the inner wall of the water inlet pipe 12 is threaded with a bottom cover 122. The swept-off fine sand and gravel accumulate at the bottom of the water inlet pipe 12. At this time, the bottom cover 122 is removed, and the swept-off fine sand and gravel are washed out with the water flow.

[0036] During the above process, although a small amount of fine sand may remain in the cavity 11, it will not cause the impeller 21 to get stuck.

[0037] The speed reduction module includes a flap 7, a spring 71, and an electric actuator 72. A receiving cavity 121 is provided inside the pump body 1 and above the inlet pipe 12. The receiving cavity 121 communicates with the inside of the inlet pipe 12. An elastic diaphragm 6 is provided at the opening of the receiving cavity 121. The upper end of the flap 7 is hinged to the inner wall of the receiving cavity 121. The lower end of the spring 71 contacts the elastic diaphragm 6. The side of the flap 7 away from the elastic diaphragm 6 is welded to the spring 71. The end of the spring 71 away from the flap 7 is welded to the top of the inner wall of the receiving cavity 121. The electric actuator 72 is fixedly installed on the top of the inner wall of the receiving cavity 121. The electric actuator 72 is perpendicular to the flap 7, and its lower end is hinged to the flap 7. The receiving cavity 121 is located near the inlet of the inlet pipe 12.

[0038] The extension of the electric actuator 72 causes the flap 7 to deflect downwards, causing the elastic membrane 6 to bulge towards the inside of the water inlet pipe 12. The bulging of the elastic membrane 6 forms a gentle slope, reducing the amount of water entering the water inlet pipe 12.

[0039] When the elastic membrane 26 bulges to its maximum, its cross-sectional width is half the inner diameter of the inlet pipe 12.

[0040] It also includes an elastic membrane 52, the edge of which is fixedly bonded to the inner wall of the cavity 11, and the elastic membrane 52 covers the groove 111 to prevent fine sand and gravel from entering the groove 111.

[0041] A sealing block 4 is threadedly connected to the top of the pump body 1 and directly above the cavity 11. A bracket 16 is fixedly installed on the top of the sealing block 4. The top of the bracket 16 is welded to the motor 2. The drive shaft of the motor 2 passes vertically through the sealing block 4.

[0042] A connecting pipe 14 is provided on the side of the cavity 11, and the end of the connecting pipe 14 away from the cavity 11 is connected to the drainage channel 13.

[0043] In summary, this water supply pump system comprises a pump body 1, a motor 2, an impeller 21, and a drain pipe 3. Adjusting the speed of the motor 2 above the pump reduces the water flow velocity entering the pump body 1, facilitating the deposition of fine sand and gravel on the inner wall of the cavity 11. The accumulation of fine sand and gravel causes the elastic diaphragm 52 to indent and contact the pressure switch 114, thereby transmitting information to the main control module 8. The main control module then operates the flap 7 to sweep away the deposited fine sand and gravel.

[0044] Furthermore, a receiving cavity 121 is provided inside the pump body 1 and located at the top of the inlet pipe 12. The receiving cavity 121 is connected to the inlet pipe 12, and a flap 7, a spring 71, and an electric actuator 72 are arranged inside the receiving cavity 121. The electric actuator 72 drives the flap 7 to rotate, causing the elastic diaphragm 6 to bulge, reducing the water flow into the inlet pipe 12. The bulging elastic diaphragm 6 acts as a buffer, achieving a secondary speed reduction. This facilitates subsequent inspection and cleaning.

[0045] Furthermore, each water supply pump is individually controlled via the central control module. Each pump is inspected sequentially, and while one pump is being inspected and cleaned, the central control module adjusts the motor speeds of the remaining pumps, ensuring that the overall water supply pump system's power output remains unaffected. This prevents a decrease in the overall efficiency of the water supply pump system due to pump maintenance.
