Here, the integrated pumping station system provided by this application includes a remote monitoring center 10, multiple integrated prefabricated pumping stations 30, and a local electrical control cabinet 20 corresponding to any integrated prefabricated pumping station 30. Among them, the remote monitoring center 10 is used for remote monitoring and control of multiple integrated prefabricated pumping stations 30 to achieve remote data collection, management and control without manual on-site inspection, and can achieve the purpose of unattended and guarded pumping stations.

Here, each integrated prefabricated pump station 30 is equipped with a local electrical control cabinet 20. The local electrical control cabinet 20 is electrically connected to each device in the integrated prefabricated pump station 30. The local electrical control cabinet 20 can control the integrated prefabricated pump station 30. Each equipment in the pumping station 30 is working.

Here, a molded case circuit breaker, a frequency converter, a PLC controller and a touch screen can be installed in the local electrical control cabinet 20, and the molded case circuit breaker, the frequency converter and the touch screen are connected to the PLC controller.

It should be noted that the integrated prefabricated pumping station 30 (Integrated prefabricated pumping station) is a lifting equipment for lifting sewage, rainwater, drinking water, and wastewater. It is a pressurized pumping station that is uniformly produced and assembled by the factory and transported to the site for installation. Usually, the integrated prefabricated pumping station 30 is composed of a top cover, a fiberglass reinforced plastic (GRP) cylinder 310, a base, a submersible sewage pump 320, a service platform, pipelines and other parts to meet the equipment for pressurization and lifting drainage requirements. As shown in Figure 1, the integrated prefabricated pumping station 30 includes a cylinder 310, a plurality of submersible sewage pumps 320 provided in the cylinder 310, and water inlet pipes and water outlet pipes provided on the cylinder 310. Generally, submersible sewage pumps The water inlet end of the submersible sewage pump 320 is connected to the water storage tank of the clean water pool through the water inlet pipe, and the water outlet end of the submersible sewage pump 320 is connected to the water inlet main pipe of the next-level integrated prefabricated pump station 30 through the water outlet pipe. Here, the submersible sewage pump 320 in this application has its own high temperature, oil leakage, and water leakage alarm functions. The submersible sewage pump 320 can choose a WQ vertical submersible centrifugal sewage pump, which adopts the latest dual-channel hydraulic design concept and has a wide flow without clogging. Impeller form design structure.

Wherein, the water inlet pipe is provided with an inlet manifold, and the water outlet pipe is provided with an outlet manifold. The water inlet of each submersible sewage pump 320 is connected to the water inlet manifold through a water inlet branch pipe. Each submersible sewage pump 320 is connected to the water inlet manifold.

In view of the situation that silt still exists inside the cylinder 310 of the integrated prefabricated pumping station 30 in the related art when it is running, this application uses CFD computer fluid dynamics analysis to control each submersible sewage pump 320. In addition, the water pump A customized flushing valve 330 is installed on the top, and a PLC controller is used to utilize the venturi effect and the pressure difference within the integrated prefabricated pumping station 30. When the water pump is started, the flushing valve 330 automatically runs for a preset time to spray the bottom and spray the sludge. Remove and completely solve the problem of silt deposition.

Here, the Venturi effect, also known as the Venturi effect, is manifested in the phenomenon that the flow rate of the fluid increases when a restricted flow passes through a reduced flow section, and its flow rate is inversely proportional to the flow section. According to Bernoulli's law, the increase in flow rate is accompanied by a decrease in fluid pressure, which is the common Venturi phenomenon. In layman's terms, this effect means that low pressure will be generated near the high-speed flowing fluid, resulting in adsorption. This effect can be used to make a venturi tube. For this application, the venturi tube is the flush valve 330. . This application uses this effect to remove the sludge at the bottom of the cylinder 310. Specifically, when gas or liquid flows in the flush valve 330 (similar to a venturi tube), the dynamic pressure reaches the maximum value at the narrowest point of the pipe. , the static pressure reaches the minimum value, the velocity of the gas (liquid) rises due to the reduction of the cross-sectional area of the flow, and the entire inrush flow must go through the pipe narrowing process at the same time, so the pressure also decreases at the same time, thereby generating a pressure difference , this pressure difference is used to measure or provide an external suction force to the fluid. When the inrush reaches the speed of sound, the Venturi tube will be called a Rafal nozzle (tapering wide nozzle), that is, the flush valve 330.

In a possible implementation, the plurality of submersible sewage pumps 320 include a first submersible sewage pump, a second submersible sewage pump, and a third submersible sewage pump, and a liquid level gauge is provided in the cylinder 310. The liquid level gauge is electrically connected to the PLC controller; wherein, the PLC controller is also used to control The first submersible sewage pump is started; when it is detected that the target liquid level drop value does not meet the pump stop condition, the second submersible sewage pump is controlled to start. If a failure of the second submersible sewage pump is detected, all the submersible sewage pumps are started. The third submersible sewage pump is started; after detecting that the target liquid level drops to meet the pump stop condition, the first submersible sewage pump and the third submersible sewage pump are controlled to stop.

Here, a pressure liquid level sensor (i.e., liquid level gauge) and float dual control are installed inside the pumping station. The continuous liquid level collected by the liquid level gauge (4~20mA) is uploaded to the local electrical control cabinet 20, which is controlled by the local electrical The PLC controller in the cabinet 20 controls its automatic start and stop and alternate operation. When the pressure level sensor fails, the float will work to ensure the reliable operation of the entire integrated prefabricated pump station 30. Among them, the pressure sensor can be equipped with a liquid level gauge installation tube to prevent interference and damage caused by entanglement of solid objects.

In addition, the integrated prefabricated pump station 30 provided by this application is a pump station based on the PLC-based intelligent prefabricated pump station control system.

As well as the utilization rate of a single pump, multiple submersible sewage pumps 320 are set to "at least two uses and one standby, and each other is standby". In this way, the utilization efficiency of the submersible sewage pumps 320 can be improved, and when any one of the submersible sewage pumps 320 fails, the integrated prefabricated pumping station 30 can continue to operate.

In one example, when the liquid level is low, the first submersible sewage pump starts for the first start; the second submersible sewage pump starts for the second start; and the third submersible sewage pump starts for the third start. When a fault occurs, it automatically switches to the next pump and alarms. When the liquid level is high, start another submersible sewage pump 320 on the basis of starting the existing submersible sewage pump 320. When a fault occurs, it will automatically switch to the next one and alarm.

If so, the waterproof motor is controlled to reverse rotation; and whether the reverse rotation duration of the waterproof motor is greater than the second duration threshold is detected. , if yes, control the waterproof motor to rotate forward; detect whether the working current of the crushing grille 340 is greater than the preset current threshold; if yes, control the waterproof motor to rotate reversely; if not, determine the normal direction of the waterproof motor. When the transfer duration reaches the third duration threshold, repeat the above steps.

Here, the crushing grid 340 is a new type of crushing equipment that crushes solid matter in sewage into fine particles. The solid matter in sewage does not need to be salvaged after being crushed, and it also protects subsequent equipment (blocking/winding/jamming). It can prevent the pipes and the submersible sewage pump 320 from being clogged, improve the subsequent treatment effect, and improve the water quality. Among them, the current of the crushing grille 340 can be monitored in real time, and the crushing grille 340 can be controlled to reverse before reaching the waterproof motor high temperature alarm to spit out the solid waste in the reverse direction to protect the crushing grille 340. Among them, the DFS500 crushing grid 340 can be selected as the crushing grid 340.

When crushing hard garbage, there is a stall phenomenon. At this time, the current of the waterproof motor increases, causing the crushing grille 340 to The motor temperature rises. Therefore, this application uses a current transmitter to monitor the grid current in real time, control the crushing grid 340 to reverse before reaching the motor high temperature alarm, spit out the solid waste in the reverse direction, protect the crushing grid 340, and automatically start the crushing grid 340 on time.
