Description
本創作係涉及一種用於輸送液體的泵浦。The invention relates to a pump for transporting liquids.
現有技術中的泵浦包含一泵殼、一增壓結構及一心軸。增壓結構設置於泵殼內；心軸的內端連接泵殼內的增壓結構，外端穿出泵殼外並且用於連接馬達或其他外部動力源。泵浦運作時，馬達透過心軸驅動增壓結構，使增壓結構對泵殼內的液體加壓並使液體朝特定方向移動。增壓結構因泵浦的類型而有各種不同構造，以離心式泵浦為例，增壓結構為一組或多組葉輪，利用葉輪旋轉的離心力對泵殼內的液體加壓。Pumps in the prior art include a pump housing, a pressurizing structure and a spindle. The pressurizing structure is arranged in the pump casing; the inner end of the mandrel is connected to the pressurizing structure in the pump casing, and the outer end passes out of the pump casing and is used to connect to a motor or other external power source. When the pump is operating, the motor drives the boosting structure through the spindle, so that the boosting structure pressurizes the liquid in the pump housing and moves the liquid in a specific direction. The supercharging structure has various structures depending on the type of pump. Taking a centrifugal pump as an example, the supercharging structure is one or more sets of impellers, which uses the centrifugal force of the impeller rotation to pressurize the liquid in the pump casing.
為避免泵殼內加壓過的液體從心軸與泵殼之間的縫隙洩漏至泵殼外，泵殼被心軸貫穿處設置有軸封。然而軸封在心軸高速運轉下，其密封性會隨時間衰退而導致泵殼內的液體發生洩漏之情況。In order to prevent the pressurized liquid in the pump casing from leaking out of the pump casing from the gap between the mandrel and the pump casing, a shaft seal is provided at the point where the pump casing is penetrated by the mandrel. However, when the spindle rotates at high speed, the sealing performance of the shaft seal will deteriorate over time, resulting in leakage of the liquid in the pump casing.
部分的液體因性質特殊而不允許洩漏情況發生，例如用於浸沒式冷卻的冷卻液。所謂浸沒式冷卻就是將電腦伺服器直接浸泡在冷卻液中，零組件產生的熱量直接傳導給冷卻液來進行散熱，藉此，伺服器不需要安裝散熱鰭片、導熱銅管或風扇等傳統風冷元件，進而使伺服器可以設計地極為緊密並且減少噪音及維修需求，但冷卻液本身必須同時具備不導電、低黏度等特殊性能，導致冷卻液價格非常昂貴而不允許洩漏。Some liquids do not allow leakage due to their special properties, such as coolants used for immersion cooling. The so-called immersion cooling means that the computer server is directly immersed in the coolant. The heat generated by the components is directly transferred to the coolant for heat dissipation. Therefore, the server does not need to install traditional cooling fins, heat-conducting copper tubes or fans. Cold components allow the server to be designed extremely compactly and reduce noise and maintenance requirements. However, the coolant itself must have special properties such as non-conductivity and low viscosity, making the coolant very expensive and not allowed to leak.
然而，現有的泵浦無法完全避免液體洩漏，實有待加以改良之必要。However, existing pumps cannot completely avoid liquid leakage and need to be improved.
有鑑於前述之現有技術的缺點及不足，本創作提供一種具防漏功能的泵浦以防止輸送的液體洩漏。In view of the above-mentioned shortcomings and shortcomings of the prior art, the present invention provides a pump with anti-leakage function to prevent leakage of the transported liquid.

In other preferred embodiments, the leakage-proof sleeve 50 can also be designed to penetrate the outer sealing wall 122 and sandwich the first sealing ring 14 between the first mounting ring groove 1222 and the leakage-proof sleeve 50 . between the torus.
防漏套筒50的另一端較佳地穿設尾蓋13的第二環突部，並且將第二密封圈15夾設於第二安裝環槽與防漏套筒50的外環面之間，進而使防漏套筒50的第二開口502被尾蓋13封閉。請配合參閱圖6所示，在其他較佳的實施例中，防漏套筒50A也可設計成套設於尾蓋13A的第二環突部132A外並將第二密封圈15A夾設於第二安裝環槽133A與防漏套筒50A的內環面之間，藉以具備美觀的功能。The other end of the leak-proof sleeve 50 is preferably inserted through the second annular protrusion of the tail cover 13 , and the second sealing ring 15 is sandwiched between the second installation ring groove and the outer ring surface of the leak-proof sleeve 50 , thereby causing the second opening 502 of the leak-proof sleeve 50 to be closed by the tail cover 13 . Please refer to FIG. 6 . In other preferred embodiments, the leakage-
在本實施例中，防漏套筒50設計成與頭座12及尾蓋13可拆卸地連接以方便維修並且易於生產，但不以此為限，防漏套筒50也可視情況設計成與頭座12或尾蓋13一體成形。In this embodiment, the leak-proof sleeve 50 is designed to be detachably connected to the head base 12 and the tail cover 13 to facilitate maintenance and production, but it is not limited to this. The leak-proof sleeve 50 can also be designed to be connected to the head base 12 and the tail cover 13 depending on the situation. The head base 12 or the tail cover 13 is integrally formed.
前述之液體偵測單元60較佳地為一液位感測裝置，其設置於尾蓋13的感測器穿孔131，當內軸封41出現洩漏時，液體偵測單元60便能藉由偵測到儲液空間105內的液體之液面高度來提醒使用者應適時安排維修。在其他較佳的實施例中，液體偵測單元60也可以是一漏液偵測器，藉由偵測儲液空間105內有無出現液體來得知內軸封41是否有洩漏的情況。The aforementioned liquid detection unit 60 is preferably a liquid level sensing device, which is disposed in the sensor hole 131 of the tail cover 13. When the inner shaft seal 41 leaks, the liquid detection unit 60 can detect The liquid level height of the liquid in the liquid storage space 105 is measured to remind the user to arrange maintenance in a timely manner. In other preferred embodiments, the liquid detection unit 60 may also be a liquid leakage detector that detects whether there is liquid in the liquid storage space 105 to learn whether there is leakage in the inner shaft seal 41 .
本發明於使用時，將入水口102及出水口103連接至欲加壓輸送的流體管路(圖中未示)，並將心軸30連接馬達(圖中未示)以使泵浦運作。當出現內軸封41處因自然老化或其他因素發生洩漏時，洩漏的液體會經由引流空間104向下流動至儲液空間105內並且被液體偵測單元60偵測到，因此使用者可藉由觀察液體偵測單元60來確認洩漏狀況並大略得知洩漏速度，有利於適時安排維修。維修時可一併回收儲液空間105內的液體。When the present invention is used, the water inlet 102 and the water outlet 103 are connected to the fluid pipeline (not shown in the figure) to be pressurized and transported, and the mandrel 30 is connected to the motor (not shown in the figure) to operate the pump. When leakage occurs at the inner shaft seal 41 due to natural aging or other factors, the leaked liquid will flow downward into the liquid storage space 105 through the drainage space 104 and be detected by the liquid detection unit 60 , so the user can By observing the liquid detection unit 60 to confirm the leakage condition and roughly know the leakage speed, it is helpful to arrange maintenance in a timely manner. During maintenance, the liquid in the liquid storage space 105 can be recovered together.
請配合參閱圖8及圖9所示，本發明的第四實施例與第一實施例大致相同，差異在於第四實施例的防漏套筒50C的壁面上貫穿形成有一連通儲液空間105C的感測器穿孔501C，也就是說，感測器穿孔131C的總數為二，液體偵測單元60C可視情況設置於尾蓋13C或防漏套筒50C。Please refer to FIGS. 8 and 9 . The fourth embodiment of the present invention is substantially the same as the first embodiment. The difference lies in that a connected liquid storage space 105C is formed through the wall of the leakage-proof sleeve 50C of the fourth embodiment. The sensor through holes 501C, that is to say, the total number of sensor through holes 131C is two, and the liquid detection unit 60C is optionally provided on the tail cover 13C or the leak-proof sleeve 50C.
在本實施例中，液體偵測單元60C設置於防漏套筒50C的感測器穿孔501C，藉此，當泵浦安裝在非水平的基座91時，防漏套筒50C上的感測器穿孔501C會位於儲液空間105C的最低處，確保液體偵測單元60C能正確地偵測液體。In this embodiment, the liquid detection unit 60C is disposed in the sensor through hole 501C of the leak-proof sleeve 50C, whereby when the pump is installed on a non-horizontal base 91, the sensing unit 60C on the leak-proof sleeve 50C The through hole 501C will be located at the lowest point of the liquid storage space 105C, ensuring that the liquid detection unit 60C can correctly detect liquid.
本實施例中的感測器穿孔131C、501C也可作為液體回收液孔使用。在其他較佳的實施例中，泵浦上另外形成有液體回收孔(圖中未示)，其貫穿泵浦的外壁並且連通儲液空間105C。液體回收孔平時則以塞頭封閉，當需要回收液體時可開啟液體回收孔以利回收儲液空間105C內的液體。The sensor through holes 131C and 501C in this embodiment can also be used as liquid recovery holes. In other preferred embodiments, a liquid recovery hole (not shown in the figure) is additionally formed on the pump, which penetrates the outer wall of the pump and communicates with the liquid storage space 105C. The liquid recovery hole is usually closed with a plug. When liquid needs to be recovered, the liquid recovery hole can be opened to facilitate recovery of the liquid in the liquid storage space 105C.
綜上所述，本發明藉由設置外密封壁122而形成引流空間104，同時藉由設置防漏套筒50而形成密封的儲液空間105。藉此，當內軸封41發生洩漏時，洩漏出的液體會被封閉在儲液空間105內而不會洩漏至泵浦外，還能被回收而不會造成浪費或汙染環境。同時，液體偵測單元60能檢知內部發生洩漏，進而提醒使用者儘速維修。To sum up, in the present invention, the drainage space 104 is formed by providing the outer sealing wall 122, and the sealed liquid storage space 105 is formed by providing the leakage-proof sleeve 50. Therefore, when the inner shaft seal 41 leaks, the leaked liquid will be enclosed in the liquid storage space 105 without leaking outside the pump, and can be recycled without causing waste or polluting the environment. At the same time, the liquid detection unit 60 can detect internal leakage, thereby reminding the user to repair it as soon as possible.
