Sewage submersible pump selection considerations

[Asia Fluid Network News] Sewage submersible pump selection of the basic parameters of diameter, flow, lift, power, voltage, liquid and so on. These parameters can not only directly show the sewage submersible pump work efficiency and work level, at the same time in product research and promotion are also of great significance. Sewage submersible pump selection should not only pay attention to the economic usefulness of the product, more attention should be paid to the use of various parameters of product attention. Sewage submersible pump selection considerations 1, according to the discharge flow and delivery of the size and height of the head to choose the right sewage pump. 2, according to the use of different power supply options single-phase or three-phase sewage pump. 3, according to the use of the need to drain liquid, and decided to use the pump or pump. 4, check the sewage pump without reliable grounding device and safety protection device, so as not to affect the safe use of sewage pumps. 5, according to the sewage pump price, quality status, operating costs and installation, maintenance and other factors to consider the selection of a suitable pump. 6, From energy saving and meet the requirements of the use of the premise, the selection of sewage pumps with higher efficiency, select the parameters of the sewage pump rated flow 0.7-1.2 times within the scope of operation. 7, the choice should pay attention to check the appearance of the pump, check the sewage pump body, the pump cover is damaged, the cable is damaged, the surface of the pump corrosive bolts are loose, there is no leakage, leakage traces, there should be megohmmeter Measure the cold insulation resistance, the installation of the standard cold insulation resistance in 50 megohms or more. 8, according to the use of different occasions, the selection of sewage pumps. For example, for the transport of high concentrations of sewage, the use of better wear-resistant sewage pump; such as for the sewage or sewage transport, will have to consider the sewage pump through the maximum particle diameter; such as the transport of corrosion-resistant medium, You should consider the selection of corrosion-resistant pump; such as the transmission of fibrous material, we must consider the selection of the sewage pump with cutting mechanism. In summary, sewage submersible pumps in the selection of the need to focus on a lot of things, these selection considerations for customers, not only in the purchase of their products to provide some knowledge of product support, at the same time when the product is used Can also achieve a multiplier effect, to a certain extent, may improve product efficiency and product life.
