The difference between sewage pumps and submersible pumps

I believe everyone is curious about the difference between sewage pumps and submersible pumps. Today, the editor will take you to learn the difference between the two.
The difference between sewage pumps and submersible pumps is mainly reflected in the following three aspects:
1. The two types of pumps have different usage processes
Submersible pumps are suitable for special process requirements, such as leaks, special fluid media, etc., and are relatively expensive. Sewage pumps are generally used for regulation, and there are also switches, such as the end of the fan coil.
2. The switch forms of the two pumps are different
The submersible pump is driven by a coil and can only be turned on or off, with a short action time when turned on or off. The drive of a sewage pump is usually driven by an electric motor, and it takes a certain amount of time to simulate the opening or closing action, which can be adjusted.
3. The working properties of the two pumps are different
Submersible pumps generally have a small flow coefficient and a small working pressure difference. For example, the flow coefficient of a 25 caliber submersible pump is much smaller than that of a 15 caliber electric ball valve. The drive of the submersible pump is through an electromagnetic coil, which is more susceptible to voltage shock damage Bad. Equivalent to the function of a switch, it has two functions: on and off.
The drive of sewage pumps is usually driven by electric motors, which are relatively resistant to voltage shocks. Submersible pumps are quick opening and quick closing, usually used in places with low flow and pressure, and require high switching frequency for sewage pumps. The opening of the sewage pump valve can be controlled, and the state
There are on, off, half on, and half off options that can control the flow rate of the medium in the pipeline, but submersible pumps cannot meet this requirement.
Submersible pumps can generally be reset after power outage, and sewage pumps need to be equipped with a reset device for such functions.
