Instructions for septic tank sewage pump
Sewage pump belongs to a type of centrifugal impurity pump, which has various forms such as submersible and dry. The commonly used submersible pump isQWType submersible sewage pump, common dry sewage pumps such asWHorizontal sewage pump andWLtypevertical sewage pump Two types. Mainly used for transporting urban sewage, feces or liquids containing fibers. The medium of solid particles such as paper scraps is usually transported by the mediumtemperaturenot greater than80℃Due to the presence of fibers that are prone to entanglement or clumping in the conveyed medium. Therefore, the flow channel of this type of pump is prone to blockage. Once the pump is blocked, it will not work properly and may even burn out the motor, resulting in poor drainage. It has a serious impact on urban life and environmental protection. Therefore, anti clogging and reliability are important factors for the quality of sewage pumps.
Types of sewage pumps for septic tanks
This type of impeller belongs to bladeless impellers, and the impeller channel is a curved channel from the inlet to the outlet. So it is suitable for pumping media containing large particles and long fibers. Good anti blocking performance. In terms of performance, this type of impeller has high efficiency and is not much different from ordinary closed impellers, but using this typeImpeller pumpThe head curve drops sharply.power curveRelatively stable and less prone to high-power issues, but the cavitation performance of this type of impeller is not as good as that of ordinary closed impellers, especially suitable for use in pumps with pressure inlets
Type of septic tank sewage pump
The common pressure chamber used in sewage pumps is a snail shell, which is internally installedsubmersible pumpRadial guide vanes or flow channel guide vanes are commonly used. There are three types of snail shells: spiral, ring, and intermediate. Spiral volutes are basically not used in sewage pumps. Circular pressurized water chambers are commonly used in small sewage pumps due to their simple structure and easy manufacturing. However, due to the emergence of intermediate (semi spiral) pressure chambers, the application range of annular pressure chambers has gradually become smaller. Due to the combination of the high efficiency of the spiral and the high permeability of the annular pressure chamber, the intermediate type pressure chamber. It has received increasing attention from manufacturers.
