Description
本創作為一種水冷卻電動抽水泵浦,尤指一種利用泵浦將水流液體加壓,經由適當的水道及密封裝置,能將泵浦輸出之正壓力水流引導流經馬達外殼表面及電子控制器導熱片,協助系統散熱之結構,如此可將馬達及控制器運轉所產生之熱能經由熱交換帶出系統,提升整體運作效率與延長使用壽命。The present invention is a water-cooled electric pump, especially a pump that pressurizes a water flow liquid, and through a suitable water channel and a sealing device, can direct a positive pressure water flow of the pump output through the motor casing surface and an electronic controller. The thermal pad helps the system to dissipate heat, so that the heat generated by the motor and the controller can be brought out of the system through heat exchange, which improves the overall operating efficiency and prolongs the service life.
於抽水泵浦的操作中,馬達在連續運轉時的冷卻,相當的重要,由於馬達線圈之電阻,以及矽鋼片在電磁交換時所持續產生的熱能,將會使馬達操作溫度升高,從而造成馬達的性能下降,同時破壞馬達線圈絕緣,進而影響馬達的使用壽命,因此馬達的散熱一直以來都是增加泵浦性能與使用壽命最重要的課題。In the operation of the pump, the cooling of the motor during continuous operation is quite important. Due to the resistance of the motor coil and the continuous heat generated by the silicon steel sheet during electromagnetic exchange, the operating temperature of the motor will increase, resulting in The performance of the motor is degraded, and the insulation of the motor coil is destroyed, which in turn affects the service life of the motor. Therefore, the heat dissipation of the motor has always been the most important issue to increase the pump performance and service life.
以往泵浦之馬達使用氣冷式設計散熱,由於氣冷式散熱構造簡單、生產成本低,向來都是散熱的主要方式,但是,空氣的熱容量較小且導熱較慢,同時安裝環境需要良好的對流,因此氣冷式設計的散熱效果受限於安裝環境因素較大,此外,氣冷式散熱之風扇運轉與氣流所產生的噪音亦會影響使用環境的品質。In the past, the pumped motor uses air-cooled design to dissipate heat. Due to the simple structure of air-cooled heat dissipation and low production cost, it has always been the main way to dissipate heat. However, the heat capacity of air is small and the heat conduction is slow, and the installation environment needs good. Convection, therefore, the cooling effect of the air-cooled design is limited by the installation environment. In addition, the noise generated by the air-cooled fan operation and the airflow will also affect the quality of the environment.
若以液體作為熱交換的介質,則可有效改善空氣導熱不易的缺點,以日常生活常見之水為例,水的導熱係數是空氣的二十三倍,也就是說水散熱的速度是遠高於空氣,而水的加壓與輸送正是泵浦運轉的目的,因此,現有技術研發出能結合輸送水並以水冷卻馬達之泵浦設計。If liquid is used as the medium for heat exchange, it can effectively improve the shortcomings of air heat conduction. For example, the water common in daily life is twenty-three times that of air, which means that the speed of water dissipation is much higher. In the air, the pressurization and delivery of water is the purpose of pump operation. Therefore, the prior art has developed a pump design that can combine the transport of water and cool the motor with water.
現有技術係利用泵浦輸送的水流進行馬達散熱,係於泵浦運轉時,位於泵浦內部之入水口形成一負壓區,從而將泵浦外部之水流吸入泵浦內,然而,水流於負壓環境下,將使水流的蒸發溫度降低,意即,只要水流因接觸物體之影響而使溫度略為升高,則水流將產生汽化現象,因此,入水口之水流於吸收馬達之熱能後,將因溫度上升以及處於負壓環境下,而發生汽化現象,由於水流之汽化現象將於泵浦內部形成汽障,汽障現象將堵塞泵浦內部水流之流動,繼而造成泵浦無法正常運轉。In the prior art, the water flow from the pump is used for heat dissipation of the motor. When the pump is running, the water inlet located inside the pump forms a negative pressure zone, thereby drawing the water outside the pump into the pump. However, the water flows in the negative. Under the pressure environment, the evaporation temperature of the water flow will be lowered, that is, as long as the water flow is slightly increased due to the influence of the contact object, the water flow will be vaporized. Therefore, after the water of the water inlet flows to absorb the heat energy of the motor, Due to the temperature rise and the negative pressure environment, vaporization occurs. Because the vaporization of the water flow will form a steam barrier inside the pump, the steam barrier will block the flow of the internal water flow of the pump, which will cause the pump to fail to operate normally.
本創作之水冷卻電動抽水泵浦之目的在於改善現有技術中,水流因泵浦內部之負壓狀態及吸熱後發生汽化現象,而造成泵浦內部水流因汽障而堵塞之缺失,尤指一種經由適當的水道,及密封設計,藉由本創作技術手段之實施,提高泵浦內部水流之壓力,繼而升高水流蒸發溫度,能將泵浦運轉輸出之正壓力水流引導流經馬達外殼表面,進行馬達散熱,如此可將馬達運轉所產生之熱能經由熱交換帶出系統,提升整體運作效率與壽命。The purpose of the water cooling electric pump of the present invention is to improve the prior art, the water flow is caused by the negative pressure state inside the pump and the vaporization phenomenon after the heat absorption, which causes the internal water flow of the pump to be blocked due to the steam barrier, especially a kind. Through the appropriate water channel and sealing design, the pressure of the internal water flow of the pump is increased by the implementation of the creative technique, and then the evaporation temperature of the water flow is increased, and the positive pressure water flow of the pump operation output can be guided to flow through the surface of the motor casing. The heat dissipation of the motor can bring the heat generated by the operation of the motor out of the system through heat exchange, thereby improving the overall operating efficiency and life.

A pressure detecting hole 162 is provided in the chamber 16 as a pressure sensing switch interface required for motor control, and a temperature switch mount 163.
請參見圖1及圖2,本創作之泵浦機殼50,結合於水冷卻馬達10之馬達外框體11形成葉輪容室14之端部,該泵浦機殼50包含有一殼體51、一入水口52、一入水通道53、一出水通道54、出水口55及一葉輪組容室56,該葉輪組容室56與馬達外框體11內之葉輪容室14形成葉輪運轉空間,於葉輪運轉空間內一個或一個以上的葉輪組60裝設於馬達軸心24上,由水冷卻馬達10驅動葉輪組60旋轉以加壓水流,每個葉輪組包含葉輪及導水器,水流於一葉輪組加壓後,並經由導水器引導流至下一葉輪組繼續加壓,該入水通道53相通於該葉輪組容室56。Referring to FIG. 1 and FIG. 2 , the pump casing 50 of the present invention is coupled to the motor outer frame 11 of the water cooling motor 10 to form an end of the impeller chamber 14 , and the pump casing 50 includes a casing 51 , a water inlet 52, a water inlet passage 53, a water outlet passage 54, a water outlet 55 and an impeller assembly chamber 56, the impeller assembly chamber 56 and the impeller chamber 14 in the motor outer casing 11 form an impeller running space, One or more impeller groups 60 in the impeller running space are mounted on the motor shaft 24, and the water cooling motor 10 drives the impeller group 60 to rotate to pressurize the water flow. Each impeller group includes an impeller and a water guide, and the water flows to an impeller. After the group is pressurized, the flow is directed to the next impeller group via the water deflector to continue the pressurization, and the water inlet passage 53 communicates with the impeller assembly chamber 56.
於本創作之水冷卻電動抽水泵浦運轉時,請參照圖1及圖2所示,水流將會由入水口52被吸入殼體51,再經由入水通道53進入葉輪組60加壓,最後流入馬達外框體11內之葉輪容室14,此時水流已經過葉輪組60加壓,因此葉輪容室14為正壓環境,此正壓環境有利於機械軸封70之操作,因為軸心24與機械軸封70間之密合面需要少量的水滲入,以維持潤滑與密封效果,而葉輪容室14之正壓環境能達成此需求,機械軸封70裝設於機械軸封安裝座141,以防止水流洩漏。When the water-cooling electric pump is operated by the present invention, as shown in FIG. 1 and FIG. 2, the water flow will be sucked into the casing 51 from the water inlet 52, and then pressurized into the impeller group 60 via the water inlet passage 53 and finally flowed in. The impeller chamber 14 in the outer casing 11 of the motor, at which time the water flow has been pressurized by the impeller group 60, so the impeller chamber 14 is a positive pressure environment, and the positive pressure environment facilitates the operation of the mechanical shaft seal 70 because the shaft center 24 The sealing surface with the mechanical shaft seal 70 requires a small amount of water to penetrate to maintain the lubrication and sealing effect, and the positive pressure environment of the impeller chamber 14 can achieve this requirement, and the mechanical shaft seal 70 is mounted on the mechanical shaft seal mount 141. To prevent water from leaking.
請參照圖1、圖2及圖4所示,加壓後之水流經由設置於葉輪容室14之內環通孔143,加壓水流進入馬達外框體11之內緣壁面及內殼體20之外緣壁面所形成之冷卻通道15,藉由水流可同時冷卻內殼體20之表面及控制器容室16內導熱板17;完成熱交換之水流再經由外環通孔144流出冷卻通道15,以進入泵浦機殼50之出水通道54,最後由出水口55流出泵浦機殼50以完成加壓輸送過程。Referring to FIG. 1 , FIG. 2 and FIG. 4 , the pressurized water flows through the inner ring through hole 143 provided in the impeller chamber 14 , and the pressurized water flows into the inner wall surface of the motor outer frame 11 and the inner casing 20 . The cooling passage 15 formed by the outer wall surface can simultaneously cool the surface of the inner casing 20 and the heat conducting plate 17 in the controller chamber 16 by the water flow; the water flow for completing the heat exchange flows out of the cooling passage 15 through the outer ring through hole 144. In order to enter the water outlet passage 54 of the pump casing 50, and finally exit the pump casing 50 from the water outlet 55 to complete the pressurized conveying process.
於本創作之水冷卻電動抽水泵浦,由於冷卻通道15及機械軸封70皆設置於正壓力之水流區,故可避免因水流壓力過低,同時水流溫度升高而導致汽化現象的產生,並且可提供機械軸封70較佳之潤滑效果,確保泵浦正常操作。In the water-cooling electric pump of the present invention, since the cooling passage 15 and the mechanical shaft seal 70 are both disposed in the water flow region of the positive pressure, it is possible to avoid the occurrence of vaporization due to the water flow pressure being too low and the water flow temperature being increased. And the mechanical shaft seal 70 can provide better lubrication effect to ensure normal operation of the pump.
實務上,由於泵浦出入口及葉輪位置配置的需要,其入口通道亦可能設置於馬達與泵浦中間,則機械軸封將處於入口通道之低壓環境。In practice, due to the need for pump inlet and outlet and impeller position configuration, the inlet passage may also be placed between the motor and the pump, and the mechanical shaft seal will be in the low pressure environment of the inlet passage.
為確保該配置之泵浦仍然能維持正壓力之冷卻通道,本創作之水冷卻電動抽水泵浦提出另一實施方式,請參照圖2及圖6所示,於馬達外框體11內之導水器安裝座142中央圓柱具有一之套合環面145,該套合環面145與泵浦機殼50之入水通道53側之機械軸封容室57內緣壁面套合密封,可隔離泵浦入水口52負壓力與葉輪容室14之正壓力環境;此種配置泵浦之水流由入水口52被吸入泵浦機殼50,再經由入水通道53進入葉輪組60加壓後,會先經由設置於葉輪容室14之外環通孔144進入馬達外框體11及內殼體20所形成之冷卻通道15,可同時冷卻內殼體20之表面及控制器容室16內之導熱板17,完成熱交換之水流再經由內環通孔143流出冷卻通道15進入泵浦出水通道54,最後由出水口55流出泵浦完成加壓輸送過程。In order to ensure that the pump of this configuration can still maintain the cooling channel of positive pressure, another embodiment of the water-cooled electric pump of the present invention is proposed. Referring to FIG. 2 and FIG. 6, the water guiding body in the outer casing 11 of the motor The central cylinder of the mounting seat 142 has a sleeved annular surface 145 which is sleeved and sealed with the inner wall surface of the mechanical shaft sealing chamber 57 on the water inlet passage 53 side of the pump casing 50 to isolate the pump. The negative pressure of the water inlet 52 and the positive pressure environment of the impeller chamber 14; the water flow of the pump is configured to be sucked into the pump casing 50 by the water inlet 52, and then pressurized into the impeller group 60 via the water inlet passage 53, and then The annular through hole 144 is disposed outside the impeller chamber 14 and enters the cooling passage 15 formed by the motor outer frame 11 and the inner casing 20, and simultaneously cools the surface of the inner casing 20 and the heat conducting plate 17 in the controller compartment 16. The water flow that completes the heat exchange flows out of the cooling passage 15 through the inner ring through hole 143 into the pump outlet passage 54, and finally flows out of the pump through the water outlet 55 to complete the pressurized conveying process.
