GERMANY KAYSEN PUMP CO .,LTD

離心曝氣機(jī)采用電機(jī)和葉輪直接傳動，利用葉輪旋轉(zhuǎn)所產(chǎn)生的離心力排開周圍水形成低壓區(qū)吸入水流同時，在葉輪處制造真空而吸入空氣，在混氣室中氣與水充分混合形成均勻的氣水混合液，在離心力作用下快速排出。
潛水離心式曝氣機(jī)產(chǎn)品為自吸式曝氣，直聯(lián)式結(jié)構(gòu)。旋轉(zhuǎn)的葉輪產(chǎn)生的離心力，在葉輪的處形成負(fù)壓吸入空氣和水，利用葉輪的功能在混合室里將一定比例的氣水混合，在強(qiáng)大的離心力下，氣水二相流沿葉輪的切線方向經(jīng)流道整流后，向圓周方向擴(kuò)散，細(xì)碎的微小氣泡充分與水相融，從而達(dá)到充氧曝氣的效果。
 

主要特點(diǎn)：

●自重定位，安裝方便，可在不中斷工藝運(yùn)行的狀態(tài)下自由布置；
●設(shè)計結(jié)構(gòu)緊湊，利用自吸功能無需外接氣源；     
●主機(jī)潛水作業(yè)減少占地面積，噪音??；    
●可直接在氧化塘中使用，節(jié)省基建成本；    
●獨(dú)立移動的曝氣裝置，曝氣時兼有攪拌功能；

●除電機(jī)外，其它部件材質(zhì)有不銹鋼、碳鋼和鑄鐵供選擇。
 

主要應(yīng)用：
潛水離心式曝氣機(jī)用于各種污水處理工程中生化處理工藝的曝氣池、曝氣沉砂池、預(yù)曝氣池、好氧硝化池曝氣充氧混合及養(yǎng)殖塘增氧。

潛水曝氣機(jī)選型：
建議從五個方面加以考慮，既液體輸送量、揚(yáng)程、液體性質(zhì)、管路布置以及操作運(yùn)轉(zhuǎn)條件等。
●流量是選離心曝氣機(jī)的重要性能數(shù)據(jù)之一，它直接關(guān)系到整個裝置的的生產(chǎn)能力和輸送能力。如設(shè)計工藝能算出離心曝氣機(jī)正常、較小、較大三種流量。選擇離心曝氣機(jī)時，以理想流量為依據(jù)，兼顧正常流量，在沒有理想流量時，通常可取正常流量的1.1倍作為理想流量。    
●揚(yáng)程是選離心曝氣機(jī)的又一重要性能數(shù)據(jù)，一般要用放大5%—10%余量后揚(yáng)程來選型。   
●液體性質(zhì)，包括液體介質(zhì)名稱，物理性質(zhì)，化學(xué)性質(zhì)和其它性質(zhì)，物理性質(zhì)有溫度c、密度d、粘度u，介質(zhì)中固體顆粒直徑和氣體的含量等，這涉及到系統(tǒng)的揚(yáng)程，有效氣蝕余量計算和合適泵的類型：化學(xué)性質(zhì)，主要指液體介質(zhì)的化學(xué)腐蝕性和毒性，是選用泵材料和選用那一種軸封型式的重要依據(jù)。    
●管路布置條件指的是送液高度送液距離送液走向，吸如側(cè)較低液面，排出側(cè)較高液面等一些數(shù)據(jù)和管道規(guī)格及其長度、材料、管件規(guī)格、數(shù)量等，以便進(jìn)行系梳揚(yáng)程計算和汽蝕余量的校核。   
●操作條件的內(nèi)容很多，如液體的操作T飽和蒸汽力P、吸入側(cè)壓力PS（*）、排出側(cè)容器壓力PZ、海拔高度、環(huán)境溫度操作是間隙的還是連續(xù)的、泵的位置是固定的還是可移的。 
 
潛水曝氣機(jī)注意事項：
●如果水泵有任何小的故障切記不能讓其工作。如果水泵軸的填料完磨損后要及時添加，如果繼續(xù)使用水泵會漏氣。這樣帶來的直接影響是電機(jī)耗能增加進(jìn)而會損壞葉輪。  
●如果水泵在使用的過程中發(fā)生強(qiáng)烈的震動這時一定要停下來檢查下是什么原因，否則同樣會對水泵造成損壞。  
●當(dāng)水泵底閥漏水時，有些人會用干土填入到水泵管里，用水沖到底閥處，這樣的做法實在不可取。因為當(dāng)把干土放入到進(jìn)水管里當(dāng)水泵開始工作時這些干土就會進(jìn)入泵內(nèi)，這時就會損壞水泵葉輪和軸承，這樣做縮短了水泵使用壽命。當(dāng)?shù)组y漏水時一定要拿去維修，如果很嚴(yán)重那就需要更換新的。  
●水泵使用后一定要注意保養(yǎng)，比如說當(dāng)水泵用完后要把水泵里的水放干凈，把水管卸下來然后用清水沖洗。  
●水泵上的膠帶也要卸下來，然后用水沖洗干凈后在光照處晾干，不要把膠帶放在陰暗潮濕的地方。水泵的膠帶一定不能沾上油污，更不要在膠帶上涂一些帶粘性的東西。  
要仔細(xì)檢查葉輪上是否有裂痕，葉輪固定在軸承上是否有松動，如果有出現(xiàn)裂縫和松動的現(xiàn)象要及時維修，如果水泵葉輪上面有泥土的也要清理干凈。  無法啟動  首先應(yīng)檢查電源供電情況：接頭連接是否牢靠；開關(guān)接觸是否緊密；保險絲是否熔斷；三相供電的是否缺相等。如有斷路、接觸不良、保險絲熔斷、缺相，應(yīng)查明原因并及時進(jìn)行修復(fù)。其次檢查是否是水泵自身的機(jī)械故障，常見的原因有：填料太緊或葉輪與泵體之間被雜物卡住而堵塞；泵軸、軸承、減漏環(huán)銹??；泵軸嚴(yán)重彎曲等。排除方法：放松填料，疏通引水槽；拆開泵體清除雜物、除銹；拆下泵軸校正或更換新的泵軸。

Submersible jet aerator

Submersible aerator

Submersible centrifugal aerator

The centrifugal aerator is directly driven by a motor and an impeller. The centrifugal force generated by the rotation of the impeller is used to discharge the surrounding water to form a low-pressure zone. At the same time, a vacuum is created at the inlet of the impeller to draw in air, and the gas and water are sufficiently mixed in the mixing chamber. The uniform gas-water mixture is quickly discharged under the action of centrifugal force.

The submersible centrifugal aerator product is self-priming aeration and direct-connected structure. The centrifugal force generated by the rotating impeller forms a negative pressure at the inlet of the impeller to draw in air and water. The function of the impeller is used to mix a certain proportion of gas and water in the mixing chamber. Under strong centrifugal force, the gas-water two-phase flow along the impeller After the tangential direction is rectified by the flow path, it is diffused in the circumferential direction, and the finely divided fine bubbles are sufficiently fused with the water to achieve the effect of oxygenation and aeration.

main feature:

● Self-repositioning, easy to install, free to arrange without interrupting the process operation;

●The design is compact, and the self-priming function does not require an external air source;

●The host diving operation reduces the floor space and the noise is small;

● It can be used directly in oxidation ponds to save infrastructure costs;

● Independently moving aeration device, which has a stirring function when aeration;

●The chassis can be specially designed according to user requirements;

●It can be added with a mesh inlet to prevent foreign matter from entering the body and causing unnecessary damage;

● The intake air amount can be adjusted through the intake valve;

● In addition to the motor, other parts are available in stainless steel, carbon steel and cast iron.

main application:

The submersible centrifugal aerator is used for aeration tanks, aerated grit chambers, pre-aeration tanks, aerobic nitrification tanks, aeration and oxygenation mixing and aquaculture pond oxygenation in various sewage treatment projects.

Submersible aerator selection:

It is recommended to consider five aspects, such as liquid delivery volume, head, liquid properties, piping layout, and operating conditions.

● Flow rate is one of the important performance data of the centrifugal aerator. It is directly related to the production capacity and conveying capacity of the entire device. For example, the design process can calculate the normal, small and large flow rates of the centrifugal aerator. When a centrifugal aerator is selected, the normal flow rate is based on the ideal flow rate. When there is no ideal flow rate, 1.1 times the normal flow rate can be taken as the ideal flow rate.

●The lift is another important performance data of the centrifugal aerator. Generally, it should be selected by amplifying the lift by 5%-10%.

● liquid properties, including liquid media name, physical properties, chemical properties and other properties, physical properties are temperature c, density d, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the lift of the system, effective gas Calculation of the amount of eclipse and the type of suitable pump: chemical properties, mainly refers to the chemical corrosiveness and toxicity of the liquid medium, is an important basis for the selection of the pump material and the type of shaft seal.

●The pipeline layout conditions refer to the data of the liquid feeding height, the liquid feeding direction, the lower liquid level of the suction side, the higher liquid level of the discharge side, and other data and pipe specifications and their lengths, materials, pipe fittings specifications, quantity, etc. In order to carry out the calculation of the combing process and the checking of the NPSH.

●The operating conditions have many contents, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, pump position is fixed Still removable.

Dive aerator notes:

● If the pump has any small faults, remember not to let it work. If the filler of the pump shaft is worn out, it should be added in time. If the pump is used continuously, it will leak. The direct effect of this is that the motor consumes more energy and can damage the impeller.

● If the pump has a strong vibration during use, be sure to stop and check what is the cause, otherwise the pump will be damaged.

● When the bottom valve of the water pump leaks, some people will fill the water pump inlet pipe with dry soil and flush it with water to the bottom valve. This is not desirable. Because when the dry soil is put into the water inlet pipe, when the water pump starts to work, the dry soil will enter the pump, which will damage the water pump impeller and the bearing, which shortens the service life of the water pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced.

●Be sure to pay attention to maintenance after using the pump. For example, when the pump is used up, put the water in the pump clean, remove the water pipe and rinse it with clean water.

● The tape on the pump should also be removed, then rinse with water and dry in the light. Do not put the tape in a dark and humid place. The tape of the pump must not be stained with oil, and do not apply some sticky material to the tape.

Carefully check the impeller for cracks. If the impeller is fixed on the bearing, if it is cracked or loose, it should be repaired in time. If there is mud on the pump impeller, clean it. Unable to start First check the power supply: whether the connector is secure; whether the switch is tight; whether the fuse is blown; whether the three-phase power supply is equal. If there is a disconnection, poor contact, fuse blown, lack of phase, the cause should be identified and repaired in time. Secondly, it is checked whether it is the mechanical failure of the pump itself. The common reasons are: the packing is too tight or the impeller and the pump body are stuck by the debris; the pump shaft, the bearing and the leak-reducing ring are rusted; the pump shaft is severely bent. Remedy: loosen the packing, dredge the water tank; disassemble the pump body to remove debris and rust; remove the pump shaft to correct or replace the new pump shaft.
