Sewage pumps and submersible pumps appear to be one type of pump, but there are actually some important differences between them. First, let's take a look at the basic working principles and usage scenarios of these two types of pumps.
A sewage pump is a type of pump that is specifically designed to discharge wastewater. Its main function is to transport sewage from one place to another, such as from toilets to sewers. Since sewage often contains large amounts of impurities and garbage, sewage pumps must be able to handle these substances without damage. In addition, sewage pumps usually have a large outlet and a higher flow rate in order to be able to discharge large amounts of sewage quickly.
In contrast, a submersible pump is a type of pump that is capable of working in submersible water. They are often used in situations where fresh or fresh water needs to be pumped, such as the water supply of swimming pools, wells, or ponds. Submersible pumps are designed so that they can operate in the water without damage, so they are often used for special process requirements, such as leak detection or the extraction of special fluid media.
Although both sewage pumps and submersible pumps are a type of water pump, they have significant differences in the use process, switching form and working characteristics. First of all, submersible pumps are usually more expensive because they are suitable for special process requirements, such as leak detection or the extraction of special fluid media. In contrast, sewage pumps are mainly used for regulation, such as regulating the flow of water or conveying sewage.
In addition, the switching form of submersible pump and sewage pump is also different. Submersible pumps are usually coil-driven and can only be operated on or off, with a short operating time when switching. In contrast, the drive of a sewage pump is usually done by the opening or closing action of the motor, which takes a certain amount of time to simulate and can be adjusted.
Finally, there are differences in the operating characteristics of submersible pumps and sewage pumps. Submersible pumps typically have a small flow coefficient and a very small operating pressure differential. In addition, since the submersible pump is driven by an electromagnetic coil, it is more susceptible to damage from voltage shocks. In contrast, the sewage pump has a larger flow coefficient and a larger working pressure difference. In addition, sewage pumps are usually driven by electric motors, so they are more resistant to voltage shocks.
When operating submersible and sewage pumps, their characteristics and requirements need to be considered. For example, due to the rapid opening and closing of submersible pumps, they are usually used in applications with low flow rates, low pressures, and high switching frequency requirements. 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. In addition, submersible pumps can be reset in the event of a power outage, while sewage pumps require a reset device for this operation.
To sum up, although sewage pump and submersible pump are both types of water pumps, there are significant differences in their use process, switching form and working characteristics. When selecting and using these two pumps, their different requirements and characteristics need to be considered to ensure that they can meet the specific application needs.
