自吸泵與離心泵有哪些區別?
很多用戶都不知道自吸泵和離心泵的區別。其實自吸泵也是離心泵的一種。它是一種泵體高度高、有一定蓄水能力的離心泵,在DY次灌水后,將底閥安裝在吸水管內即可吸水。所以自吸泵也可以叫離心泵。自吸泵和離心泵的主要區別在于,上海鈦龍自吸泵的進水管在DY次充水后可以吸水,不需要安裝底閥,以后也不需要加水。泵體比離心泵大,很多都有存水和自吸終身的功能,而離心泵起增壓的作用,液位必須比泵高,所以只有流入泵體后才能啟動。如果液位低于離心泵的液位,只能通過在進口管道的吸入口安裝底閥向泵和管道內充入液體,或者在進口安裝導水筒,如泵長時間不工作的離心泵,才能實現自吸功能, 當泵第二次啟動時,入口管道和泵體中的水基本上沒有了,需要再次注水,操作起來很麻煩,因為長期不使用的離心泵入口處的底閥密封不能達到完全密封的效果,液體會慢慢漏回池中,所以在自吸功能的工作條件下,WATERSUNNY自吸離心泵都采用軸向回液的泵體結構。 離心泵的泵體由吸入室、儲液室、渦旋室、回液孔、氣液分離室等組成。離心泵正常啟動后,葉輪將吸入室中儲存的液體和吸入管中的空氣一起吸入,在葉輪中完全混合。在離心力的作用下,液體夾帶氣體向渦室外緣流動,在葉輪外緣形成一定厚度的白色泡沫帶和高速旋轉的液環。氣液混合物通過擴散管進入氣體分離室。此時,由于流速突然降低,較輕的氣體從混合液體中分離出來,氣體繼續上升,并通過泵體的排出口排出。脫氣后的液體返回儲液室,通過回流孔再次進入葉輪,與從葉輪內部吸入管吸入的氣體再次混合,在高速旋轉的葉輪作用下流向葉輪外緣。隨著這個過程的不斷進行,吸入管道中的空氣不斷減少,直到空氣排出,自吸泵完成自吸過程,離心泵投入正常運行。由于離心泵具有這種D特的排氣能力,自吸泵無需安裝底閥即可輸送含氣液體,在游輪上使用時具有良好的掃艙功能。1.一些離心泵的軸承體底部有冷卻室。當軸承的溫度由于軸承的加熱而上升到70℃以上時,冷卻室可以充滿冷卻液管接頭,如冷卻液循環冷卻,如VAREM的IH化學泵。ZILMET離心泵中防止液體從高壓區泄漏到低壓區的密封機構是前后密封圈,前密封圈安裝在泵體上,后密封圈安裝在軸承體上。當泵長期運行后磨損到一定程度,影響泵的效率和自吸性能時,應更換。當葉輪高速旋轉時,葉輪帶動葉片之間的液體一起旋轉。由于離心力的作用,液體從葉輪中心拋向葉輪外緣(流速可提高到15 ~ 25m/s),動能也隨之增加。當液體進入泵殼時,由于蝸殼形泵殼內的流道逐漸膨脹,液體的流速逐漸減小,一部分動能轉化為靜壓能,于是液體以較高的壓力沿出口流出。同時,由于液體被甩出,在葉輪中心形成一定的真空,液面壓力Pa高于葉輪中心,因此吸入管道的液體在壓差的作用下進入泵內。葉輪不斷旋轉,液體不斷被吸出并壓出。離心泵之所以叫離心泵,是因為它主要靠離心力來輸送液體。
What are the differences between self-priming pump and centrifugal pump?
Many users do not know the difference between self-priming pump and centrifugal pump. In fact, self-priming pump is also a centrifugal pump. It is a centrifugal pump with high body height and certain water storage capacity. After the first irrigation, the bottom valve can be installed in the water absorption pipe to absorb water. So self priming pump can also be called centrifugal pump. The main difference between self-priming pump and centrifugal pump is that the water inlet pipe of Shanghai titanon self-priming pump can absorb water after the first water filling, and it does not need to install the bottom valve, and no water is needed later. The pump body is larger than the centrifugal pump, many of which have the function of water storage and self-priming for life. However, centrifugal pump plays a role of boosting. The liquid level must be higher than that of the pump, so it can only be started after it enters the pump body. If the liquid level is lower than the level of centrifugal pump, the self-priming function can only be achieved by installing the bottom valve at the suction port of the inlet pipe to fill the pump and the pipeline with liquid, or installing the water guide tube at the inlet, such as the centrifugal pump which does not work for a long time, When the pump is started for the second time, the water in the inlet pipe and pump body is basically absent, so it needs to be refilled. It is very difficult to operate. Because the bottom valve seal at the inlet of the centrifugal pump that is not used for a long time can not achieve the complete sealing effect, and the liquid will slowly leak back into the pool. Therefore, under the working condition of self-priming function, the water self-priming centrifugal pump adopts the pump body structure of axial return liquid . The pump body of centrifugal pump consists of suction chamber, liquid storage room, vortex chamber, return hole, gas-liquid separation chamber, etc. After the centrifugal pump is started normally, the impeller will suck the liquid stored in the suction chamber and the air in the suction pipe together, and mix it completely in the impeller. Under the action of centrifugal force, the liquid entrainment gas flows to the outer edge of the vortex chamber, forming a thick white foam belt and a high-speed rotating liquid ring at the outer edge of the impeller. The gas-liquid mixture enters the gas separation chamber through the diffusion tube. At this time, due to the sudden decrease of flow rate, the lighter gas is separated from the mixed liquid, and the gas continues to rise and is discharged through the discharge port of the pump body. The degasified liquid returns to the liquid storage chamber, and enters the impeller again through the return hole, and then mixes with the gas inhaled from the inner suction pipe of the impeller, and flows to the outer edge of the impeller under the action of the impeller with high speed rotation. With the continuous progress of this process, the air in the suction pipe is decreasing until the air is discharged. The self-priming pump completes the self-priming process, and the centrifugal pump is put into normal operation. Because of the unique exhaust capacity of centrifugal pump, the self-priming pump can deliver the gas containing liquid without the installation of bottom valve, and has good function of cabin cleaning when used on cruise ship. 1. cooling chamber is provided at the bottom of bearing body of some centrifugal pumps. When the temperature of the bearing rises above 70 ℃ due to the heating of the bearing, the cooling chamber can be filled with coolant pipe joints, such as the coolant circulating cooling, such as the IH chemical pump of varem. The sealing mechanism of zilmet centrifugal pump to prevent liquid leakage from high pressure area to low pressure area is front and rear sealing ring, front sealing ring is installed on pump body and rear sealing ring is installed on bearing body. When the WaterSunny pump is worn to a certain extent after long-term operation, which affects the efficiency and self-absorption performance of the pump, it should be replaced. When the impeller rotates at high speed, the impeller drives the liquid between the blades to rotate together. Due to the centrifugal force, the liquid is thrown from the center of the impeller to the outer edge of the impeller (the flow rate can be increased to 15 ~ 25m/s), and the kinetic energy increases. When the liquid enters the pump shell, the flow velocity of the liquid decreases gradually because the flow passage in the volute type pump shell expands gradually, and a part of the kinetic energy is converted to static pressure energy, so the liquid flows out along the outlet with high pressure. At the same time, because the liquid is dumped, a certain vacuum is formed in the center of the impeller, and the liquid level pressure PA is higher than the impeller center, so the liquid in the suction pipe enters the pump under the action of pressure difference. The impeller is rotating, and the liquid is constantly sucked out and pressed out. Centrifugal pump is called centrifugal pump because it mainly relies on centrifugal force to transport liquid.
