Determination of submersible sewage pump flow

 Many customers in the purchase of submersible sewage pump, usually only say what they want to use, but the sewage pump flow, head and so is not clear, resulting in some customers to buy the submersible sewage pump or traffic is not enough to meet the demand for sewage; Either traffic is too large, the cost of electricity costs money. How to determine the appropriate submersible sewage pump flow, in general, can be considered from the following aspects:

1, when you can adjust the displacement of the time, usually selected by the maximum flow per hour. Fire elevator drainage pool within the drainage pump flow is not less than 10L / s, submersible sewage pump suction flow should be 0.7m / s and 2.0m / s between. 

2. When the impurities in the sewage large, the pool of the submersible sewage pump out of the water pipes should not be excluded, so as not to reduce the flow, the water pipe blockage; when the impurities in the sewage in general, can be considered concentrated to enhance sewage efficiency; When the submersible sewage pump to promote large containing debris, the submersible sewage pump should be equipped with automatic mixing or cutting device, in order to avoid flow reduction, decreased efficiency, but also to avoid damage to the submersible sewage pump.

When the motor power is greater than or equal to 7.5kW can be fixed by the pump self-coupling device; when the submersible sewage pump motor power is less than 7.5kW, can be installed mobile hose installation.

In addition, the sewage pump can generally 0.7 to 1.2 times the rated flow range of normal operation (submersible sewage pump can be 0.7 to 1.3 times the rated flow range of normal operation), beyond this range may produce overload, requiring users to select and When using a submersible pump, the appropriate range must be considered. Especially for multi-stage deep submersible pumps, in considering how to determine the submersible pump head more need to pay attention to: high-lift submersible pumps, not for low head, so as not only a waste of energy, but also damage the submersible pump.
