Description

Integrated sewage lifting pump well structure

Technical Field

The utility model relates to the technical field of sewage lifting, in particular to an integrated sewage lifting pump well structure.

Background

The integrated sewage lifting pump station is very popular in the design of a sewage pipe network system, and the function of the integrated sewage lifting pump station is mainly to solve the problem of conveying sewage from a low-topography interface to a high-topography interface. The conventional integrated sewage lifting pump station is mostly of a buried cylindrical closed structure, adopts a glass fiber reinforced plastic material (corrosion resistant), is formed by combining a coupling type submersible sewage pump, a gate valve, a check valve, a stainless steel pipeline and a water inlet grid, is assisted by a PLC (programmable logic controller) automatic control system to realize automatic start and stop or remote control, is reserved in a tank body, a short pipe of a water inlet flange and a short pipe of a water outlet flange are communicated with an external sewage pipe network, and then equipment manufacturers assemble complete equipment according to a design atlas, but a large number of practices prove that the design structure still exposes a plurality of defects, such as:

(1) Because the integrated sewage tank body equipment (glass fiber reinforced plastic) is most cylindrical, the top cover is in a sphere shape, the wellhead is circular, the upper end of a guide rod of the sewage pump is fixed on an overhaul platform in the tank body, and the lifting point of the installation position of the sewage pump is not centered, when the sewage pump is blocked, the insulation of a motor is lowered and a coil is burnt out and needs to be lifted out, an maintainer must go down to the overhaul platform to push the sewage pump, so that the guide claw of the pump is separated from the guide rod, and when the pump is recycled, the maintainer must go down to pull the guide claw of the sewage pump to bite the guide rod, so that the pump body can be coupled in a sliding way along the guide rod, which is quite inconvenient;

(2) The conventional design is that a gate valve and a check valve are placed in a tank body, and because the sewage contains strong corrosive substances, the gate valve and the check valve are extremely easy to rust and have faults, and the check valve is most easy to damage, once the check valve is out of order, the check valve is opened, closed or semi-opened and semi-closed, at the moment, maintenance personnel must go into a well for a long time to disassemble or replace the check valve, but if the gate valve is further out of order, a sewage main pipe cannot be emptied, the check valve is disassembled to cause sewage backflow, so that the check valve cannot be replaced and can not be disassembled for maintenance, and the check valve cannot be disassembled or maintained, two consequences are caused, namely, the check valve is blocked, the effluent flow is suddenly reduced, the sewage cannot be pumped out immediately, and when other pumps run, the sewage flows back from the pump well, so that serious consequences of incapability of running and incapacity of maintenance of a lifting pump station are caused, and serious risk of sewage overflow occur;

(3) The integrated pump is put into operation, the tank body is dirty and has a large number of floaters, and the concentration of toxic and harmful gases is extremely high, so that the danger and unpredictability of the integrated pump still exist even if the limited space operation regulation and the operation flow are followed, and the integrated pump is a great threat to the life safety of operators;

(4) And the valve well sedimentation valve component cracks, namely, the valve well is basically built on backfill soil and is affected by uneven sedimentation due to the split design of a valve well structure and a tank body structure, so that the cracking phenomenon of a gate valve and a check valve can occur.
