The sewage pump is a large family of water pumps. If the subdivision is also very large, different types of sewage pumps are used in different ways. Then, as a member of this large family, what are the differences between the sewage pump and the submersible pump?
Submersible pumps generally deal with clean water, while sewage pumps, as the name suggests, deal with sewage problems. There will be various magazines and garbage in the sewage, which will have a relatively large impact on the pump body. The water they pump is different, and the purpose is different. Naturally, their pump bodies will also have essential differences, such as the process, the switch form, the nature of work, etc., let's take a look at it in detail below:
1) Use process
Submersible pumps are 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 regulation, and there are also switches, such as the end of the fan coil.
2) Switch form
The submersible pump is driven by a coil and can only be turned on or off, and the action time is short when it is turned on and off. The drive of the sewage pump generally uses a motor, and it takes a certain amount of time to complete the opening or closing action, which can be adjusted.
3) Nature of work
Submersible pumps generally have a small flow coefficient, and the working pressure difference is small. For example, a general 25-caliber submersible pump has a much smaller flow coefficient than a 15-caliber electric ball valve. The submersible pump is driven by an electromagnetic coil, which is easily damaged by voltage shocks. It is equivalent to the function of a switch, which is the two functions of on and off.
4) The sewage pump is generally driven by a motor, which is relatively resistant to voltage shocks. Submersible pumps are quick-opening and quick-closing. They are generally used in places with the small flow and low pressure, and sewage pumps where a high switching frequency is required. The opening degree of the sewage pump valve can be controlled, and the state is open, closed, half-open, and half-closed, and can control the flow of the medium in the pipeline, but the submersible pump cannot meet this requirement.
5) Generally, the submersible pump can be reset after power off. The sewage pump needs a reset device for this function.
The above is the introduction of the difference between the sewage pump and the submersible pump, regardless of the process, the form of the switch, and the nature of the work. It is best to choose according to actual needs in life.
