Sewage pump is widely used in municipal engineering, factories, commercial, hospitals, hotels, residential areas and other sewage discharge, which has simple installation, small footprint, easy maintenance, no noise, etc..
Vertical sewage pump, pump and motor coaxial, so that the weight of the rotating parts and impeller bearing the same direction of water pressure. The connecting flange on the pipe bending in welding, the sewage pump and pipeline is connected by the flange bolt, the flange on the pipe bending, so the sewage pump will cause side, rotating parts of the weight of total pressure in one direction, so a long time, the internal structure of sewage pump will appear in single direction wear;
Secondly, the sewage pump is used in the liquid, the transport of sewage media containing impurities, sludge and other substances, but due to the daily sewage particles too much, so the impeller is particularly serious wear;
Sewage pump is a kind of centrifugal pump, in its operation, the power always increases with the increase of flow, when the flow exceeds the design flow and reach a certain value, the motor will be burned due to overload.
These problems will affect the life of the sewage pump to varying degrees. Know the problem, we must find a way to solve:
1. you can use the gasket thickness, or buy a rubber sealing material, sealing material by processing bias, then put into the sealing position between the sewage pump and pipe flange, adjust the position to be properly sealed can.
2.valve set filter in front of a sewage pump pipeline valve, filter and then put on a three valve, as long as the frequently used tools for extracting large particles from the three through the valve or impurities can be, this can reduce the influence of impurities on the sewage pump.
3. it is easy to handle, the selection of time, not because I feel wasted, on the choice of the theory of power. Flow increases, power is also increased, if the choice of time, the power of sewage discharge pump is not small, then the general flow increase or decrease, the impact on the sewage pump is not large.
