Submersible sewage pump is a commonly used pump used to discharge liquids containing solid particles or sewage. However, there is some discussion and misunderstanding about whether submersible sewage pumps can be used without being fully submerged in water. This article will introduce the working principle and characteristics of the submersible sewage pump, why the pump should be completely immersed in water, and the possible impacts and precautions caused by incomplete immersion in water.
Submersible sewage pumps are usually designed to be completely immersed in liquid. Their working principle relies on the static pressure of the liquid to guide the fluid into the pump body and discharge it through the discharge port of the pump. Complete immersion in water helps cool and lubricate the pump, providing the necessary hydraulic conditions to ensure normal operation of the pump. Additionally, full immersion in water reduces noise and vibration, increasing pump efficiency and longevity.
However, for certain applications, it may sometimes be required that the submersible pump is not completely immersed in the water. This situation may occur in the following situations: First, when the liquid level drops, the pump may not be fully immersed in the water, but still needs to continue to discharge liquid. Secondly, some special application scenarios, such as mine drainage or sludge treatment in sewage treatment plants, may require partial immersion in water to handle liquids.
Incomplete immersion in water may cause some effects and challenges on the operation of the submersible sewage pump. First, incomplete immersion results in insufficient cooling and lubrication conditions for the pump, which may lead to increased pump temperature and increased friction. This can lead to reduced pump performance, damaged parts, or even overheating failure. Secondly, incomplete immersion may also cause the water diversion efficiency of the pump to decrease, affecting the drainage capacity and efficiency. In addition, due to partial immersion in liquid, the accumulation and clogging of solid particles need to be considered.
When using a submersible sewage pump, there are several considerations to consider if partial submersion in water is required. First, make sure that the water inlet of the pump is not blocked by solid particles or blockages to avoid clogging and damage to the pump. Secondly, regularly check the temperature and lubrication condition of the pump to ensure that the pump is operating under appropriate temperature and lubrication conditions. In addition, depending on the actual situation, it may be necessary to increase the cooling measures of the pump or take other cooling measures to maintain the normal operating temperature of the pump.
To sum up, submersible sewage pumps are usually designed to work completely submersed in water. While less than complete immersion in water may be necessary in certain circumstances, the possible implications and challenges need to be noted. Incomplete immersion in water may result in insufficient cooling and lubrication conditions for the pump, reduced water diversion efficiency, and accumulation and clogging of solid particles. When performing partial immersion operations, it is necessary to check and maintain the temperature and lubrication status of the pump, and take appropriate cooling measures to ensure normal operation of the pump and extend the service life of the pump.
