How to distinguish between sewage pump and submersible pump

1. The process of using the two pumps is different.

Submersible pumps are suitable for some special process requirements, such as leakage, special fluid media, etc., and the price is the most expensive. Sewage pumps are generally used to adjust and switch quantities, such as at the end of fan coil units.

2. The formal establishment 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 of the switch is known. Sewage pumps are usually driven by electric motors. It takes a certain amount of time analog to complete the formal establishment action, which can be adjusted.

3. The working properties of the two pumps are different.

The general circulation system of the submersible pump is very small, and the working pressure difference is also very small. For example, the general coefficient of 25 caliber is much smaller than that of 15 caliber electric ball valve. Submersible pumps are driven by solenoids, which are more easily damaged by voltage surges. Equivalent to the function of the switch, it is the two functions of the switch.

Sewage pumps are generally driven by motors, which are more resistant to voltage shocks. The submersible pump switches quickly and is generally used for sewage pumps with small flow, low pressure and high switching frequency. The opening of the sewage pump valve can be controlled, the state can be opened, closed, half-opened and half-closed, and the flow of the medium in the pipeline can be controlled. The submersible pump cannot meet this requirement.

Submersible pumps are generally resettable when power is off, and sewage pumps need to be equipped with a reset device.

The above 3 points are the difference between sewage pump and submersible pump.
