Description

Technical Field

[0001] This application relates to the field of water absorption chambers, and particularly to a water absorption chamber for a circulating pump. Background Art

[0002] The water absorption chamber of the circulating pump is a part of the circulating pump. The circulating pump refers to a pump used to transport the circulating liquid for reaction, absorption, separation, and regeneration of the absorption liquid in the device. Its head is relatively low and is only used to overcome the pressure drop of the circulating system. A low-head pump can be used. The circulating pump refers to the function of the pump, while the centrifugal pump refers to the structure of the pump. The two are completely different concepts. The working principle of the circulating pump is that the pump used to circulate the water is called a circulating pump. For example, the hot water in the water heating and supply pipeline is circulated by the circulating pump.

[0003] In the prior art, during the use of the water absorption chamber of the circulating pump, the efficiency of the circulating pump is not well improved, and it does not have the performance of cavitation resistance. This limits the service life of the water absorption chamber of the circulating pump during use.

[0004] After retrieval, as disclosed in a Chinese patent document for a water absorption chamber for a PCS recirculation pump (Publication No.: CN202597243U), there are still the following defects:

[0005] Although the above-mentioned water absorption chamber for the PCS recirculation pump realizes the efficiency and cavitation resistance performance of the recirculation pump, its efficiency improvement of the recirculation pump is very limited only through the straight cone shape, and the cavitation resistance performance is not significantly improved either. Utility Model Content

[0006] In order to improve the problems of poor efficiency and poor cavitation resistance of the water absorption chamber of the circulating pump in the prior art, this application provides a water absorption chamber for a circulating pump.

[0007] The water absorption chamber for a circulating pump provided by this application adopts the following technical solutions:

[0008] A water absorption chamber for a circulating pump includes a water absorption chamber body of the circulating pump. A number of buffer balloons are installed on the inner side wall of the water absorption chamber body of the circulating pump, and limiting silica gel bumps are installed inside each buffer balloon. A transmission inner liner is arranged inside the water absorption chamber body of the circulating pump, and the outer side wall of the transmission inner liner is connected to the outer side wall of the buffer balloon. A number of groups of flow stabilizing corrugated plates are installed at equal intervals on the inner side wall of the transmission inner liner.

[0009] By adopting the above technical solutions, through the arranged buffer balloons, when the transmission inner liner is in the transmission process, the situation of the transmission inner liner shaking can be effectively avoided. And during the transmission process, through the flow stabilizing corrugated plates, the liquid to be transmitted can be guided and stabilized, avoiding the unstable phenomenon of the liquid during the transmission process.

[0010] Preferably, a corrosion-resistant protective housing is closely attached to the outer side wall of the main body of the circulating pump suction chamber, and the corrosion-resistant protective housing is arranged in an annular structure.

[0011] By adopting the above technical solution, through the corrosion-resistant protection of the corrosion-resistant protective housing, the situation of corrosion on the outer shell of the main body of the circulating pump suction chamber can be avoided.

[0012] Preferably, a first connection port is arranged at one end of the main body of the circulating pump suction chamber, and a second connection port is arranged at the other end of the main body of the circulating pump suction chamber.

[0013] By adopting the above technical solution, the first connection port and the second connection port are connected and fixed to other components of the circulating pump, so as to carry out the transmission operation.

[0014] Preferably, a plurality of fixing bolts are equally spaced and penetrated through one end of the first connection port and the second connection port.

[0015] By adopting the above technical solution, the first connection port and the second connection port are connected to other components through the fixing bolts.

[0016] Preferably, a waterproof rubber ring is closely attached to one end of the first connection port and the second connection port, and the waterproof rubber ring is arranged in an annular structure.

[0017] By adopting the above technical solution, after the first connection port and the second connection port are connected to other components, the waterproof rubber ring improves the sealing effect therebetween.

[0018] Preferably, an anti-cavitation coating is coated on the inner side wall of the transmission inner liner.

[0019] By adopting the above technical solution, through the anti-cavitation coating coated on the inner side wall of the transmission inner liner, the anti-cavitation effect of the inner side wall of the transmission inner liner can be effectively improved during the use process.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By using the provided transmission inner liner, the hydraulic loss is small during the liquid transmission process, which helps to improve the transmission efficiency. And when the liquid impacts the inner wall of the transmission inner liner during the liquid transmission process, the buffer balloon can be used to ensure the problem of the transmission inner liner. At the same time, for the transmitted liquid, due to the group flow stabilizing corrugated plate arranged in a waveform structure, the wave shape can be effectively avoided during the liquid transmission process, resulting in instability during the transmission process. This helps to improve the transmission efficiency of the main body of the circulating pump suction chamber, thus improving the practicability and the use efficiency;

[0022] 2. The inner wall of the transmission inner tank made of stainless steel material is used as the inner cavity of the water suction chamber body of the circulating pump. At the same time, the inner wall of the transmission inner tank is coated with an anti-cavitation coating, which further improves the anti-cavitation performance and thus extends the service life of the device.

[0029] As Figures 1 to 4 shown, the present utility model provides a water suction chamber of a circulating pump, which includes a water suction chamber body 1 of the circulating pump. The inner side wall of the water suction chamber body 1 is arranged in a conical structure, and buffer balloons 7 are fixedly connected in an array on the inner side wall of the water suction chamber body 1. The buffer balloons 7 are arranged in an inflated structure, and hemispherical limiting silica gel bumps 8 are fixedly connected inside the buffer balloons 7. The outer side wall of the buffer balloon 7 is fixedly connected to the outer side wall of the transmission inner tank 9 arranged in a conical structure. The inner side wall of the transmission inner tank 9 is made of stainless steel material, and flow-stabilizing corrugated plates 10 arranged in a waveform structure are fixedly connected at equal intervals on the inner side wall of the transmission inner tank 9. The inner side wall of the transmission inner tank 9 is coated with an anti-cavitation coating 11, and the anti-cavitation coating 11 is made of nickel-based alloy material.

[0030] By setting the transfer inner tank 9, during the process of transferring liquid in the transfer inner tank 9, since the transfer inner tank 9 is set in a conical structure, the hydraulic loss is small, which helps to improve the transfer efficiency. And when the liquid impacts the inner wall of the transfer inner tank 9 during the liquid transfer process, the buffer balloon 7 can ensure the problem of the transfer inner tank 9. The movement of the buffer balloon 7 is limited by the limit silica gel bump 8. At the same time, for the transferred liquid, due to the set of flow-stabilizing corrugated plates 10 with a waveform structure, it can effectively avoid the appearance of waves during the liquid transfer process, resulting in instability during the transfer process. This helps to improve the transfer efficiency of the suction chamber body 1 of the circulation pump. And the inner side wall of the transfer inner tank 9 is set in a stainless steel material structure, and at the same time, the inner wall is coated with an anti-cavitation coating 11, which further improves the anti-cavitation performance.

[0031] As Figure 1 shown, specifically, the outer side wall of the suction chamber body 1 of the circulation pump is fixedly connected with a corrosion-resistant protective housing 2 set in an annular structure, and the inner side wall of the corrosion-resistant protective housing 2 is closely attached to the outer side wall of the suction chamber body 1 of the circulation pump.

[0032] By setting the corrosion-resistant protective housing 2, it can effectively protect the outside of the suction chamber body 1 of the circulation pump, thereby avoiding the corrosion of the outer wall surface of the suction chamber body 1 of the circulation pump caused by long-term use or problems in the use area.

[0033] As Figure 1 and Figure 3 shown, further, the two ends of the suction chamber body 1 of the circulation pump are respectively provided with a first connection port 3 and a second connection port 4 communicated with the transfer inner tank 9. A plurality of fixing bolts 5 are threadedly connected through the inside of the first connection port 3 and the second connection port 4, and the fixing bolts 5 are set in an equidistant structure. One end of each of the first connection port 3 and the second connection port 4 is fixedly connected with a waterproof rubber ring 6 for sealing the connection part. The waterproof rubber ring 6 is set in an annular structure.

[0034] By setting the first connection port 3 and the second connection port 4, the device is connected and fixed to other components of the circulation pump for transfer operation, and the connection part between the first connection port 3 and the second connection port 4 and other components of the circulation pump is sealed by the waterproof rubber ring 6.

[0035] The principle and process of the present utility model:

[0036] First, both the first connection port 3 and the second connection port 4 are connected and fixed to other components of the circulation pump through the fixing bolts 5 connected by threaded penetration;

[0037] Secondly, the connection part between the first connection port 3 and the second connection port 4 and other components of the circulation pump is sealed by the waterproof rubber ring 6;

[0038] After that, the transfer inner tank 9 transfers the liquid. During the liquid transfer process, when it impacts the inner wall of the transfer inner tank 9, the buffer balloon 7 can be used to ensure the problem of the transfer inner tank 9. The movement of the buffer balloon 7 is limited by the limit silica gel bump 8. At the same time, due to the set of flow-stabilizing corrugated plates 10 with a waveform structure for the transferred liquid, it can effectively avoid the appearance of waves during the liquid transfer process, resulting in instability during the transfer process. This helps to improve the transfer efficiency of the circulating pump suction chamber body 1;

[0039] Finally, the inner side wall of the transfer inner tank 9 is made of a stainless steel material structure, and an anti-cavitation coating 11 is coated on the inner wall. This further improves the anti-cavitation performance. And through the set corrosion-resistant protective shell 2, it can effectively protect the outside of the circulating pump suction chamber body 1, thereby avoiding the corrosion of the outer wall surface of the circulating pump suction chamber body 1 caused by problems during long-term use or in the use area. In this way, the use of such a circulating pump suction chamber is completed.

[0040] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
