Submersible pump and sewage pump What are the differences between it

Submersible pumps and sewage pumps What are the differences? How should we distinguish? Today, we Shanghai sewage pump manufacturers and we simply talk about, I hope to help you.

    First, the use of submersible pumps and sewage pumps are different

    Submersible pumps for some special process requirements, such as leakage, special fluid medium, the price is more expensive. Sewage pumps are generally used for regulation, there are switching capacity, such as fan coil end. 

    Second, the submersible pump and sewage pump switching methods are also different

    Submersible pump through the coil drive, can only open or close, switch action time is short. Sewage pump drive is generally used motor, open or close action to complete a certain amount of time to do analog, you can do adjustment.

    Third, the working properties of submersible pumps and sewage pumps are different. 

    Submersible pump general circulation coefficient is very small, and the working pressure difference is very small. For example, the general diameter of the submersible pump diameter of 15 than 15-valve ball valve is much smaller. Submersible pump drive is through the electromagnetic coil, relatively easy to be damaged by voltage shock. Equivalent to the role of the switch is to open and close the two roles.

    Sewage pump drive is generally used motor, more resistant to voltage shock. Submersible pump is fast opening and fast closing, generally used in small flow and small pressure, the required switching frequency of the local sewage pump and vice versa. Sewage pump valve opening can be controlled, the state has on, off, half open halfway, you can control the flow of media in the pipeline submersible pumps fail to meet this requirement. 

    Submersible pump can be reset the general power, sewage pump to such a function need to add reset device.
