Sewage pump selection

Sewage pump selection is the basic parameters of diameter, flow, head, power, voltage, liquid, etc.

1, according to the flow rate of discharge and delivery lift of size and choose the appropriate sewage pump.

2, according to different occasions of the reasonable selection of sewage pump. Used for conveying high sediment concentration of sewage, for example, choose a good wear-resistance sewage pump; If it is used for conveying wastewater or sewage, want to consider the by maximum particle diameter of sewage pump; Such as corrosion medium, should consider to choose corrosion pump; As fiber material, want to consider to choose belt cutting mechanism of sewage pump.

3, choose according to use the power of different single phase or three phase sewage pump.

4, according to the requirement need all liquid, and decided to use the pump or under pump.

5, according to the sewage pump price, quality, operation cost and installation, maintenance is convenient wait for a factor to consider to choose the right pump.

6, from under the premise of energy saving and meets the requirement, and the use of high efficiency sewage pump, selection of the parameters of the sewage pump run in 0.7 1.2 times the rated flow range.

7, check whether there is any reliable grounding device on sewage pump and safety protection device, so as not to affect the safety of sewage pump use.

8, when the choice must pay attention to check the pump appearance, check the sewage pump body, pump bore without damage, the cable is damaged, the surface of the pump with and without etchant bolts are loose, without leakage, water marks, shall also have the measure cold insulation resistance by megger, installation standard cold insulation resistance in more than 50 ohms.
