管道清水泵和污水泵在构造上的区别

date.png 2019-03-25 16:52:02

污水泵属于离心泵范围,结构和原理和一般离心泵是一样的。污水泵也有自身的结构特点,污水泵的扬程都不高,由于污水中杂物较多,叶轮的间隙比清水泵大。污水泵容易产生的故障,和一般离心泵也是相似的,因为抽污水,所以叶轮磨损较快。

   管道清水泵是以获得高效率而设计的,也就是说,管道清水泵的水力结构参数是获得高效率的组合。对污水泵、这类有特殊要求的泵其效率不可能超过同一时期的清水泵效率。

污水泵、效率低于管道清水泵的主要原因是它们的过流通道加宽了。效率下降的值主要与加宽的程度有关。污水泵流道加宽是为防止阻塞。

污水泵的叶轮,比清水泵简单,没有护圈,这样就不会当住污草,叶轮的下面还有一个锯齿片,可以上下调节,能把线头,布片绞碎并抽出。

Sewage pump belongs to the scope of centrifugal pump. Its structure and principle are the same as that of general centrifugal pump. Sewage pump also has its own structural characteristics, the head of the sewage pump is not high, because there are more impurities in the sewage, the clearance of impeller is larger than that of clean water pump. Sewage pump is prone to failure, and the general centrifugal pump is similar, because the sewage pumping, so the impeller wear faster.


Pipeline water pump is designed to achieve the highest efficiency, that is to say, the hydraulic structure parameters of the water pump is the best combination to achieve the highest efficiency. The efficiencies of sewage pumps and pumps with special requirements can not exceed the efficiencies of clean water pumps in the same period.


The main reason why sewage pumps are less efficient than clean water pumps is that their passages are widened. The decrease of efficiency is mainly related to the extent of broadening. The sewage pump runner is widened to prevent blockage.


The impeller of the sewage pump is simpler than that of the clean water pump and has no guard ring, so it will not be used as dirt grass. There is also a saw-tooth blade under the impeller, which can be adjusted up and down to grind the thread head and cloth pieces and pull them out.
