旋涡泵是指叶轮为外缘部分带有许多小叶片的整体*,液体在叶片和泵体流道中反复做旋涡运动的泵。旋涡泵虽属于叶片式机械的范畴,但其工作过程、结构以及特性曲线的形状等与离心泵和其他类型泵都不太相同。


主要特点:

旋涡泵是结构最简单的高扬程泵。与相同尺寸的离心泵相比,它的扬程比离心泵高2~4倍;与相同扬程的容积泵相比,它的尺寸要小得多,结构也简单得多。
旋涡泵的效率很低(由于液体在流道内撞击损失较大),*不超过45%,通常为15%~40%。因此,它难做成大功率的泵。从如今生产的旋涡泵来看,功率一般不超过30 kw。但低比转数的离心泵效率比它还低,因此,旋涡泵代替低比转数的离心泵使用的场合是很多的。
大多数旋涡泵都具有自吸能力,有些旋涡泵还可以抽气或抽送汽液混合物,这是一般离心泵无能为力的。
具体来说,对于闭式叶轮旋涡泵,只要设置一个简单的附加装置即可以自吸。对于开式叶轮、闭式流道的旋涡泵来说,它具有自吸能力,通常用于抽气;而开式叶轮、开式流道的旋涡泵则用作输送液体,不能自吸。通常这两种泵组装在一起,前者作为抽真空泵,后者作为工作泵。例如,加油车的旋涡泵,还有其他结构的旋涡泵。
 

主要应用:
在化学工业中输送酸、碱及其他腐蚀性液体,要求泵具有小流量、高扬程、较慢的化学反应速度和较高的耐腐蚀性。由于旋涡泵的工作零件简单,因此易于实现上述要求。
抽送介质密度小的液体(如汽油、酒精等)。由于这些液体易于挥发,因此抽送时多为汽液混输,如机场、汽车配油站,甚至于飞机的加油。旋涡泵能进行汽液混输,在上述情况下工作,一般时间短,所以,效率低就不是主要问题了。
抽送含有气体的液体,抽送含有高弹性气体的液体(如丙烷、丁烷等)。抽送吸入管中部分蒸发的液体。
用于小型自动化泵站,农业供水。
用于城市公用建设,如增压辅助泵、家庭用水等。
代替液环泵作真率泵和低压压缩机。
用于汽出及船用洗涤、饮水、消防等辅助设备。
用于小型锅炉辅助设备,用以供水。

旋涡泵常见故障排除法:
       1、故障:旋涡泵消耗功率过大
  解决办法:放松填料压盖,更换叶轮。关小闸阀,减小流量。
  2、故障:旋涡泵不吸水,压力表剧烈跳动
  解决办法:灌足引水,检查管路,排除漏气现象。
  3、故障:出口压力表指示有压力,泵出水很少或不出水解决办法:降低管阻。
  解决办法:检查电机转向,除去叶轮堵塞物。增加转速。
  4、故障:漩涡泵流量低于设计流量
  解决办法:除去堵塞物,更换密封环,增加转速至铭牌上的规定值。
  5、故障:旋涡泵内声音反常,泵不出水
  解决办法:检查吸水管有无堵,清理底阀,降低液体温度或降低吸水高度。
  6、故障:旋涡泵噪声大
  解决办法:调整旋涡泵和电机,保证同心,更换新轴承。
  7、故障:旋涡泵轴承发热
  解决办法:加油,换好油或粘度小的油。更换轴承。调整泵和电机,保证同心。
  8、故障:真空表指示高度真空,泵仍不吸水。
  解决办法:检查底阀活门灵活性,除掉堵塞物,尽量使吸水管路简单。降低吸水高度。
  9、故障:水泵振动
  解决办法:调整泵和电机使轴线对准,叶轮通过平衡试验,不平衡重量要求在3克左右,更换轴承。
  不管任何的设备机械,在使用上或多或少都会遇到一些故障或者问题,只要在故障出现时,及时的解决,还是可以保证正常工作的。所以,要重视平时的操作方法与保养维护,是保证旋涡泵运行的关键。


Vortex pump

Vane pump



The vortex pump refers to a pump in which the impeller is an integral wheel with many small blades on the outer edge portion, and the liquid repeatedly performs a vortex motion in the blade and the pump body flow passage. Although the vortex pump belongs to the category of vane machinery, its working process, structure and shape of the characteristic curve are not the same as those of centrifugal pumps and other types of pumps.



main feature:


●The vortex pump is the simplest high-lift pump. Compared to a centrifugal pump of the same size, its lift is 2 to 4 times higher than that of a centrifugal pump; it is much smaller and simpler in construction than a positive displacement pump.

●The efficiency of the vortex pump is very low (due to the large impact loss of the liquid in the flow channel), the maximum is no more than 45%, usually 15% to 40%. Therefore, it is difficult to make a high-power pump. From the perspective of vortex pumps produced today, the power generally does not exceed 30 kw. However, the efficiency of a centrifugal pump with a low specific speed is lower than that of a centrifugal pump, and therefore, the vortex pump is used in place of a low specific speed centrifugal pump.

● Most vortex pumps have self-priming capability. Some vortex pumps can also pump or pump vapor-liquid mixture, which is a powerless pump.

Specifically, for a closed impeller vortex pump, it is self-priming as long as a simple attachment is provided. For open-type impellers, closed-flow vortex pumps, it has self-priming capability and is usually used for pumping; while open-type impellers and open-flow vortex pumps are used to transport liquids and cannot self-prime. Usually these two pumps are assembled together, the former as a vacuum pump and the latter as a working pump. For example, the vortex pump of a fuel truck has other vortex pumps.

 


main application:

● The transport of acids, bases and other corrosive liquids in the chemical industry requires pumps with low flow rates, high lifts, slow chemical reaction rates and high corrosion resistance. Since the working parts of the vortex pump are simple, it is easy to achieve the above requirements.

● Pumping liquids with low media density (such as gasoline, alcohol, etc.). Because these liquids are easy to volatilize, they are often mixed with vapor and liquid during pumping, such as airports, car distribution stations, and even aircraft refueling. The vortex pump can perform vapor-liquid mixing and work under the above conditions, and the general time is short. Therefore, low efficiency is not a major problem.

● Pumping a liquid containing a gas and pumping a liquid containing a highly elastic gas (such as propane, butane, etc.). The partially evaporated liquid in the suction tube is pumped.

●Used for small automated pumping stations and agricultural water supply.

●Used for urban public construction, such as booster auxiliary pumps, household water, etc.

● Replace the liquid ring pump as a true rate pump and a low pressure compressor.

●Used for auxiliary equipment such as steaming and marine washing, drinking water and fire fighting.

●Used for small boiler auxiliary equipment for water supply.


Vortex pump common troubleshooting method:

       1, fault: vortex pump consumes too much power

Solution: Loosen the packing gland and replace the impeller. Close the small gate valve to reduce the flow.

2, failure: the vortex pump does not absorb water, the pressure gauge beats vigorously

Solution: Fill the water, check the pipeline, and eliminate the air leakage.

3. Fault: The outlet pressure gauge indicates that there is pressure, and the pump has little or no water. Solution: Reduce the pipe resistance.

Solution: Check the motor steering to remove the impeller blockage. Increase the speed.

4. Fault: vortex pump flow is lower than design flow

Solution: Remove the blockage, replace the seal ring, and increase the speed to the specified value on the nameplate.

5, fault: the sound in the vortex pump is abnormal, the pump does not produce water

Solution: Check the suction pipe for blockage, clean the bottom valve, lower the liquid temperature or lower the water absorption height.

6, fault: vortex pump noise

Solution: Adjust the vortex pump and motor to ensure concentricity and replace the new bearing.

7, fault: vortex pump bearing heat

Solution: Refuel, change oil or oil with low viscosity. Replace the bearing. Adjust the pump and motor to ensure concentricity.

8. Fault: The vacuum gauge indicates a high vacuum and the pump still does not absorb water.

Solution: Check the flexibility of the bottom valve to remove the blockage and try to make the suction pipe as simple as possible. Reduce the water absorption height.

9, fault: pump vibration

Solution: Adjust the pump and motor to align the axis. The impeller passes the balance test. The unbalanced weight requirement is about 3 grams, and the bearing is replaced.

Regardless of any equipment machinery, there will be some faults or problems in use, as long as the fault occurs, and timely solution can still ensure normal operation. Therefore, it is the key to ensure the operation of the vortex pump to pay attention to the usual operation methods and maintenance.
