Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotor pump equipment, in particular to a rotor pump with a pressure relief protection function. Background Art
[0002] The rotor pump is a commonly used centrifugal pump. The design of the rotor pump is based on the principles of fluid mechanics, including the calculation and analysis of parameters such as the speed, flow rate, and pressure of the liquid flowing inside the pump. This involves relevant theories such as fluid dynamics and hydraulics. During the operation of the pump, if there is a system blockage, pipe blockage, improper valve closure, etc., the outlet pressure of the pump will rise rapidly, exceeding the limit of the pump itself, causing damage to the pump or even explosion. The rotor pump with pressure relief protection function can automatically relieve pressure in the event of overpressure, protecting the pump and related equipment from damage.
[0003] The traditional rotor pump is composed of components such as the pump casing, impeller, pump shaft, suction port and discharge port. When the motor is started, the pump shaft begins to rotate, driving the impeller to rotate together. When the impeller rotates, due to the shape of the blades, the liquid is sucked into the center part of the impeller and is forced to move outward as the impeller rotates. The sucked liquid is thrown out by the centrifugal force of the impeller and guided to the discharge port through the flow channel in the pump casing, thereby drawing the liquid into the pump from the suction port and discharging it from the discharge port. The pressure difference in the pump casing drives the flow of the liquid, thereby forming a continuous fluid flow, realizing the liquid delivery and the operation of the pump.
[0004] However, traditional rotor pumps cannot quickly disassemble the pressure relief valve. The inability to quickly disassemble the pressure relief valve will increase the difficulty of maintenance and cleaning, requiring more time and effort to perform maintenance operations. Long-term maintenance and downtime will increase maintenance costs and production losses, affecting the overall operating cost. It will also reduce the operability, maintainability and safety of the pump system, limiting its flexibility and efficiency in actual applications. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a rotor pump with a pressure relief protection function, comprising a support frame 1, a rotor pump body 2 is fixedly connected to the upper surface of the support frame 1, a pressure relief valve 4 is arranged on the outer wall of the rotor pump body 2, a pressure relief pipe 3 is fixedly connected inside the pressure relief valve 4, a pressure gauge 5 is fixedly connected to the upper surface of the pressure relief valve 4, a support plate 6 is fixedly connected to the side wall of the pressure relief valve 4, a hollow column 1 7 is fixedly connected inside the support plate 6, a hollow column 1 7 is slidably connected to the outer wall of the hollow column 1 7, a sliding column 9 is slidably connected to the outer wall of the hollow column 2 8, a spring 10 is arranged on the outer wall of the hollow column 2 8, a ball 11 is arranged inside the hollow column 2 8, a support column 12 is slidably connected inside the hollow column 1 7, a spring 2 13 is arranged on the outer wall of the support column 12, the ball 11 is engaged with the hollow column 1 7, one end of the spring 2 13 is fixedly connected to the inside of the hollow column 1 7, and a support assembly is arranged on the side wall of the support frame 1;
[0025] Specifically, by pushing the sliding column 9 to slide on the outer wall of the hollow column 2 8, this action squeezes the spring 10, making the whole structure active. At this time, the pressure relief valve 4 can be pulled to move. Since the pressure relief valve 4 is connected to the support plate 6, its movement will drive the support plate 6 and the hollow column 1 7 connected thereto to move together. The movement of the hollow column 1 7 further pushes the ball 11 to slide upward inside the hollow column 2 8. This is an ingenious design. The sliding of the ball 11 not only plays a role of connection and guidance, but also ensures the stability and smoothness of the whole structure. At the same time, the movement of the hollow column 1 7 It also causes spring 2 13 to start rebounding, and this rebound force drives the support column 12 to slide inside the hollow column 1 7. It is worth noting that the spring 2 13 on the right will also rebound at the same time, pushing the support column 12 on the right to slide inside the hollow column 2 8. This series of complex actions ultimately realizes the disassembly of the pressure relief valve 4, so that it can be easily removed. In this way, the user can thoroughly clean the pressure relief valve 4 or the rotor pump body 2 to ensure their performance and service life. This design not only simplifies the disassembly process, but also improves the maintainability and service life of the equipment, bringing great convenience to the user.
[0026] Reference Figure 1 and Figure 4 The support assembly includes a support block 14, which is fixedly connected to the side wall of the support frame 1, and a fixed plate 15 is fixedly connected to the side wall of the support block 14. A rotating column 16 is rotatably connected inside the fixed plate 15, and a fixed column 18 is fixedly connected to the upper surface of the rotating column 16. A rotating plate 17 is rotatably connected to the side wall of the fixed plate 15, and the fixed column 18 is slidably connected to the inside of the rotating plate 17. A fixed column 2 19 is fixedly connected to the inside of the rotating plate 17, and a sliding block 20 is rotatably connected to the outer wall of the fixed column 2 19. A hollow plate 21 is slidably connected to the side wall of the sliding block 20, and one end of a spring 3 24 is fixedly connected to the inside of the fixed plate 15;
[0027] Specifically, when the connecting column 22 starts to move, it will pull the hollow plate 21 to move synchronously, and this action will cause the sliding block 20 to slide inside the hollow plate 21. The sliding of the sliding block 20 is not isolated. It is linked with the fixed column 19 to make the rotating plate 17 rotate on the side wall of the fixed plate 15. As the rotating plate 17 rotates, the fixed column 18 slides inside the rotating plate 17, further prompting the rotating column 16 to rotate on the side wall of the fixed plate 15. This series of actions are completed in a very short time, but they play a vital role in the work of the rotor pump. In this series of actions, the action of the protective sleeve 25 is particularly noteworthy. When the rotor pump body 2 is relieving pressure, the protective sleeve 25 will temporarily leave the outer wall of the pressure relief pipe 3 due to the effect of pressure. This design cleverly utilizes the change in pressure so that the protective sleeve 25 can move flexibly when needed to adapt to the need for pressure relief. After the rotor pump body 2 completes the pressure relief, there is no pressure impact, and the protective sleeve 25 will fit tightly to the outer wall of the pressure relief pipe 3 again under the action of the rebound force of the spring three 24. In this way, foreign objects can be effectively prevented from entering the interior of the pressure relief pipe 3, thereby avoiding the problem of blockage of the pressure relief pipe 3.
[0028] Reference Figure 1 and Figure 4 The other end of the spring three 24 is fixedly connected to the connecting column 22, the fixing column two 19 is fixedly connected to the outer wall of the connecting column 22, the inside of the fixing plate 15 is fixedly connected to the hollow sleeve 23, the connecting column 22 is slidably connected to the inside of the hollow sleeve 23, and one end of the connecting column 22 is fixedly connected to the protective sleeve 25, and the protective sleeve 25 is fitted with the pressure relief pipe 3;
[0029] Specifically, the pressure relief valve 4 determines whether the pressure relief process can proceed smoothly. When the pressure relief valve 4 is opened, the pressure in the rotor pump body 2 will drop rapidly. This is caused by the pressure difference. In order to effectively reduce the pressure, the rotor pump body 2 is depressurized through the pressure relief pipe 3. During the pressure relief process, the high-pressure gas will be discharged rapidly through the pressure relief pipe 3, generating a strong impact force. This impact force will directly act on the protective sleeve 25, causing it to be subjected to the effect of pressure. Due to the effect of pressure, the protective sleeve 25 will drive the connecting column 22 to slide inside the hollow sleeve 23. This sliding process is not unobstructed, but will be restricted and guided by the internal structure of the hollow sleeve 23. As the connecting column 22 slides inside the hollow sleeve 23, it will squeeze the spring three 24, causing it to be compressed. The spring three 24 is designed to deform when subjected to pressure to absorb and buffer the impact force. Therefore, under the squeezing of the connecting column 22, the spring three 24 will shrink, thereby reducing the impact of the impact on other parts of the system.
[0030] Working principle: when it is necessary to clean or maintain the pressure relief valve 4 or the rotor pump body 2, first push the sliding column 9 to slide on the outer wall of the hollow column 2 8. The movement of the sliding column 9 will squeeze the spring 10. At this time, the pressure relief valve 4 can be pulled to move. The movement of the pressure relief valve 4 will drive the support plate 6 to move. The movement of the support plate 6 will drive the hollow column 17 to move. The movement of the hollow column 17 will push the ball 11 to slide upward inside the hollow column 2 8. At the same time, the movement of the hollow column 17 will cause the spring 2 13 to rebound and drive the support column 12 to slide inside the hollow column 17. At the same time, the right spring 2 13 will also rebound and drive the right support column 12 to slide inside the hollow column 2 8. At this time, the pressure relief valve 4 will be removed, and then the pressure relief valve 4 or the rotor pump body 2 can be cleaned. When the rotor pump body 2 is relieved, first open the pressure relief valve 4. The opening of the pressure relief valve 4 will cause the rotor pump body 2 to relieve pressure. The rotor pump The main body 2 will release pressure through the pressure relief pipe 3, and then the pressure will impact the protective sleeve 25 to drive the connecting column 22 to slide inside the hollow sleeve 23. The sliding of the hollow sleeve 23 will squeeze the spring three 24 to shrink it. At the same time, when the connecting column 22 moves, it will drive the hollow plate 21 to move and cause the sliding block 20 to slide inside it. The sliding of the sliding block 20 will cause the fixed column two 19 to drive the rotating plate 17 to rotate on the side wall of the fixed plate 15. The rotation of the rotating plate 17 will drive the fixed column one 18 to slide inside it. The sliding of the fixed column one 18 will drive the rotating column 16 to rotate on the side wall of the fixed plate 15. At this time, when the rotor pump body 2 is relieved, the pressure will cause the protective sleeve 25 to leave the outer wall of the pressure relief pipe 3. After the rotor pump body 2 is depressurized, there is no pressure to impact the protective sleeve 25, which will cause the spring three 24 to rebound and cause the connecting column 22 to drive the protective sleeve 25 to protect the pressure relief pipe 3, so that foreign objects will not enter the pressure relief pipe 3 and cause it to be blocked.
