Background

The negative pressure drainage system is a system which uniformly collects sewage distributed in a negative pressure intelligent collector at the tail end of a tree-shaped negative pressure collection pipe network into a negative pressure power center at the tail end of the system through negative pressure. Therefore, as the number of the negative pressure collectors increases, the number of faults also increases greatly, so that the faults of the negative pressure collectors greatly influence the stability of the whole negative pressure drainage system.

The existing negative pressure intelligent collector comprises a water collecting terminal, a sewage suction pipe, an interface valve, a pilot valve and a liquid level switch. Most negative pressure collectors in the current stage are interface valves which are opened to directly perform pumping work, so that faults are mainly in two directions, the collectors do not work, and the collectors work excessively. The collector does not work, and the negative pressure intelligent collector does not work due to the damage of system elements and other reasons, so that sewage cannot be collected in time to cause the phenomenon of sewage bottom surface cross flow; the excessive work of the collector is represented by continuous pressure relief of the system, pressure relief of the pump station, continuous alarm and reduction of the overall efficiency. In the pumping process of the product at the present stage, the pipeline is always below the liquid level, so that the gas can not enter while the sewage enters, and the gas-liquid ratio in the system is seriously damaged. Meanwhile, products at the present stage can only forecast the pressure relief condition of the system at a pump station, but specific reasons and fault places cannot be analyzed, and further, a large amount of time is consumed for finding fault points and repairing the fault points in later maintenance.
