Description

Technical Field

[0001] This utility model belongs to the field of compressor stuffing boxes, and specifically relates to a closed-loop cooling water circulation system for compressor stuffing boxes. Background Technology

[0002] Stuffing glands are widely used in many industries such as shipbuilding, power distribution cabinet manufacturing, locomotives and rolling stock, bridges, power and communications. They are also used in compressors and are a very common tool nowadays. Nowadays, cooling water is used to circulate and cool the stuffing glands of compressors to ensure the stability of the equipment during operation.

[0003] The existing reciprocating compressor stuffing box has a small cooling water passage and uses circulating water of poor quality as the cooling medium. After a period of use, mud and debris will clog the cooling water pipes, resulting in a short service life of the stuffing box. It is necessary to shut down the machine and clean the scale inside before reinstalling the original stuffing. This reduces the long-cycle operation time of the unit, reduces the number of standby units, increases the workload of maintenance personnel, and wastes time. At the same time, the increased number of repairs also reduces the service life of the equipment and increases the operating cost. Utility Model Content

The first water inlet pipe is installed at the water inlet end of the first conveying pump and is connected to the inside of the storage component. The first conveying pipe is installed at the water outlet end of the first conveying pump and is connected to the internal components of the cooling assembly.

[0008] As a preferred technical solution of this utility model, the conveying assembly further includes a second inlet pipe, a second conveying pump, and a second conveying pipe. The second conveying pump is a backup pump body for the first conveying pump. The second inlet pipe is installed at the inlet end of the second conveying pump, and the second conveying pipe is installed at the outlet end of the second conveying pump. The second inlet pipe is connected to the first inlet pipe, and the second conveying pipe is connected to the first conveying pipe.

[0009] As a preferred embodiment of this invention, a temperature detector for detecting the internal coolant temperature is provided outside the second delivery pipe.

[0010] As a preferred embodiment of this utility model, the cooling assembly includes a cooler, a circulating water inlet pipe, a circulating water outlet pipe, and a feeding pipe. The cooler is positioned above the first conveying pump, and the end of the first conveying pipe is connected to the cooler. The cooler is externally provided with a circulating water inlet pipe and a circulating water outlet pipe for conveying circulating cooling water to cool the coolant inside the cooler. A feeding pipe for conveying the cooled coolant is installed at the top of the cooler, and a temperature detector for detecting the temperature of the coolant inside the feeding pipe is externally provided.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 and Figure 2As shown, it is a structural schematic diagram of the compressor stuffing box cooling water closed-loop circulation system in this embodiment, including a storage component 1, a conveying component 2, a cooling component 3, and a cooling component 4. The storage component 1 is connected to the conveying component 2 for conveying coolant through a pipe on its side. The conveying component 2 is equipped with a cooling component 3 for controlling the temperature of the coolant. The cooling component 3 is equipped with a cooling component 4 at its top.

[0026] In use, demineralized water is stored as coolant inside storage unit 1. Then, through the operation of conveying component 2, the coolant inside storage unit 1 is transported and collected, and then input into cooling component 3. Through the operation of cooling component 3, the temperature of the coolant itself is controlled. During the cooling process, the coolant does not come into direct contact with the cooling water inside cooling component 3, ensuring the water quality of the coolant and preventing mud and debris from clogging the pipes. Afterward, the coolant is input into the cooling unit 4 to be cooled, and the cooling unit 4 is cooled. The coolant with absorbed heat is then input back into storage unit 1, completing the recycling of resources.

[0027] From the appendix Figure 3 As shown, it is a structural schematic diagram of the conveying component 2 in this embodiment. The conveying component 2 includes a first conveying pump 21, a first water inlet pipe 22 and a first conveying pipe 23. The first conveying pump 21 is disposed on the side of the storage component 1. The first water inlet pipe 22 is installed at the water inlet end of the first conveying pump 21 and is connected to the inside of the storage component 1. The first conveying pipe 23 is installed at the water outlet end of the first conveying pump 21 and is connected to the internal components of the cooling component 3.

[0028] During use, the coolant stored inside the storage unit 1 is extracted through the cooperation of the first water inlet pipe 22, the first delivery pump 21 and the first delivery pipe 23, and the coolant is input into the cooling component 3, so that the cooling component 3 can cool the coolant and make the coolant temperature reach the predetermined value, thus providing power for the overall operation of the system.

[0029] From the appendix Figure 3 As shown, this is a schematic diagram of the conveying component 2 in this embodiment. The conveying component 2 also includes a second inlet pipe 24, a second conveying pump 25, and a second conveying pipe 26. The second conveying pump 25 is a spare operating pump body for the first conveying pump 21. The second inlet pipe 24 is installed at the inlet end of the second conveying pump 25, and the second conveying pipe 26 is installed at the outlet end of the second conveying pump 25. The second inlet pipe 24 is connected to the first inlet pipe 22, and the second conveying pipe 26 is connected to the first conveying pipe 23.

[0030] During use, the installation of the second delivery pump 25 and the cooperation between the second inlet pipe 24 and the second delivery pipe 26 enable the second delivery pump 25 and the first delivery pump 21 to serve as backup pumps for each other, ensuring stable operation of the auxiliary equipment. When the first delivery pump 21 malfunctions, the second delivery pump 25 can operate in a timely manner, ensuring normal operation of the equipment.

[0031] From the appendix Figure 3 As shown, a temperature detector is installed on the outside of the second delivery pipe 26 to detect the internal coolant temperature. During use, the coolant temperature can be monitored in real time, and in conjunction with the operation of the subsequent cooling components 3, the coolant temperature can be accurately controlled.

[0032] From the appendix Figure 4 As shown, this is a schematic diagram of the structure of the cooling component 3 in this embodiment. The cooling component 3 includes a cooler 31, a circulating water inlet pipe 32, a circulating water outlet pipe 33, and a feeding pipe 34. The cooler 31 is located above the first delivery pump 21. The end of the first delivery pipe 23 is connected to the cooler 31. The cooler 31 is provided with a circulating water inlet pipe 32 and a circulating water outlet pipe 33 for conveying circulating cooling water to cool the coolant inside the cooler 31. The top of the cooler 31 is equipped with a feeding pipe 34 for conveying the cooled coolant. A temperature detector for detecting the temperature of the coolant inside the feeding pipe 34 is provided outside the feeding pipe 34.

[0033] In use, the cooler 31 is used in conjunction with the first delivery pump 21 to input coolant into the cooler 31. The circulating water inlet pipe 32 and the circulating water outlet pipe 33 are used to continuously input circulating cooling water into the cooler 31 to remove heat from the coolant. During this process, the coolant does not come into direct contact with the cooling water to ensure the quality of the coolant itself. When the coolant temperature reaches a predetermined value, the coolant is input into the part to be cooled 4 to cool the material inside the part to be cooled.

[0034] From the appendix Figure 4 As shown, the cooling component 4 is equipped with three sets of packing glands to be cooled, and all of them are connected to the end of the feeding pipe 34 through pipelines. The packing glands are equipped with return collection pipes that send the coolant back to the storage component 1. In use, the coolant is cooled by the cooperation of multiple sets of pipelines in the cooling component 4. Furthermore, the packing glands with heat can be recovered in the future, reducing resource consumption.

[0035] From the appendix Figure 5As shown, this is a structural schematic diagram of the storage component 1 in this embodiment. The storage component 1 includes a collection chamber 11, a demineralized water replenishment pipe 12, and a liquid level detector 13. The collection chamber 11 is a storage chamber for storing demineralized water as coolant. The demineralized water replenishment pipe 12, which replenishes the collection chamber 11 with demineralized water in a timely manner, is installed on one side of the surface of the collection chamber 11. A liquid level detector 13 is provided on the side of the collection chamber 11 to detect the total amount and level of coolant inside the collection chamber 11. During use, the liquid level detector 13 accurately detects the total amount of demineralized water stored inside the collection chamber 11. When the total amount of demineralized water inside the collection chamber 11 reaches a predetermined threshold, the demineralized water replenishment pipe 12 can automatically operate to replenish the demineralized water inside the collection chamber 11 in a timely manner, ensuring the stability of the equipment during operation. Moreover, the use of demineralized water can effectively reduce the pollution of the pipeline when the coolant flows inside the pipeline, ensuring the stability of the pipeline itself during use.
