The difference between sewage pump and submersible pump
Sewage pumps are generally driven by motors, which are relatively resistant to voltage shocks. Submersible pumps are quick-open and quick-close, and are generally used in places with small flow and small pressure, where the switching frequency is required to be large, and vice versa. The opening of the sewage pump valve can be controlled, and the state is open, closed, half-open and half-closed, which can control the flow of the medium in the pipeline, but the submersible pump cannot meet this requirement. The following is a brief introduction to the difference between a sewage pump and a submersible pump:
1. The use of the two pumps is different. The submersible pump is suitable for some special process requirements, such as leakage, special fluid medium, etc., and the price is more expensive. Sewage pumps are generally used for adjustment, and there are also switching quantities, such as: the end of the fan coil unit.
2. The switching forms of the two pumps are different. The submersible pump is driven by a coil and can only be turned on or off, and the action time is short when switching. The drive of the sewage pump is generally performed by a motor, and it takes a certain amount of time to complete the on or off action, which can be adjusted.
3. The working properties of the two kinds of pumps are different. The submersible pump generally has a small flow coefficient and a small working pressure difference. For example, the general flow coefficient of a 25-caliber submersible pump is much smaller than that of a 15-caliber electric ball valve. The driving of the submersible pump is through the electromagnetic coil, which is relatively easy to be damaged by the voltage shock. Equivalent to the role of a switch, that is, on and off.
