Introduction
Among many types of equipment for sewage treatment, dry sewage pump has become a key equipment with advantages and limitations in specific application scenarios because of its unique installation mode and distinctive performance characteristics.
The dry sewage pump needs to be installed in a special pump room, and the main body of the pump is fixed in the pump room through independent bases and bolts. Its advantages are very obvious.For example, in some industrial wastewater treatment scenes, the wastewater may contain strong acid, strong alkali or other chemicals with strong corrosiveness. Because of its independent installation, the dry sewage pump can effectively avoid the direct damage of these corrosive media to the external metal structure of the pump body, thus significantly prolonging the service life of the equipment. The long-term stable operation state also keeps its failure rate at a low level, which reduces the problems of sewage discharge interruption or treatment process stagnation caused by sudden equipment failure.
Compared with submersible sewage pump, dry sewage pump is independently installed in the pump room, which is less corroded by sewage, long service life, low failure rate and convenient maintenance. However, its disadvantages are also obvious, such as large area, high installation requirements, high noise and high investment cost.
However, its disadvantages are also obvious, such as large area, high installation requirements, high noise and high investment cost. This also limits its wider application. In the actual engineering planning and equipment selection process, it is necessary to comprehensively consider various factors, weigh the advantages and disadvantages, and carefully decide whether to use dry sewage pump according to the specific sewage discharge demand, site conditions, budget constraints and environmental requirements, so as to ensure the selection of the most suitable sewage equipment.
