A control method, a control system, and a non-transient computer-readable storage medium are provided. The control method is applicable to a pumping station comprising one or more pumps. The method may include: comparing an inflow rate of the pumping station with a flow rate for optimal energy consumption of the pumping station; determining, based on whether the inflow rate of the pumping station is greater than or equal to, or less than or equal to, the flow rate for optimal energy consumption of the pumping station, a corresponding constraint that indicates whether a target outflow rate of the pumping station is to be greater than or equal to, or less than or equal to, the flow rate for optimal energy consumption of the pumping station; and setting a target outflow rate that meets the constraint, for constant flow rate control of the pumping station.

The utility model discloses an oscillating screw drill movable valve assembly with a flow switching function, which relates to the field of oil and gas drilling downhole tools and comprises an overflowing component and a flow adjusting part. The overflowing assembly comprises a movable valve plate, a flow dividing seat and a hollow anti-falling rod which are sequentially arranged from top to bottom and are axially through, an eccentric hole for drilling fluid to flow in is formed in the movable valve plate, and a center hole and a plurality of flow dividing holes located in the periphery of the center hole are formed in the flow dividing seat; the flow adjusting piece is detachably arranged between the center hole and the hollow anti-falling rod and comprises a center spray pipe and a center plug which are alternatively arranged so as to be used for changing the communication state between the center hole and the hollow anti-falling rod, and then the outflow flow of the flow dividing holes is adjusted. The drilling fluid flow can be conveniently and rapidly adjusted, the whole anti-falling rod does not need to be replaced, and the replacement efficiency is improved.

This application discloses a flow control method, apparatus, and medium for a spray device. The flow control method includes setting a target outflow rate at the outlet of the spray device; determining a predetermined liquid level within the spray device; introducing at least two chemical solutions into the inlet of the spray device to mix them within the device, forming a mixture, with the mixture being discharged from the outlet simultaneously with the inlet; and controlling the inlet flow rate such that when the inlet inflow time is a first predetermined time, the liquid level within the spray device increases to the predetermined level, and the inlet flow rate equals the target outflow rate, and the outlet flow rate is close to or equal to the target outflow rate, so that the mixing time of the mixture within the spray device is a second predetermined time. This application enables the mixture to mix within the spray device for a second predetermined time, which helps achieve better substrate treatment results when the mixture is supplied to the substrate surface.

This invention provides a wastewater pipeline network monitoring method and a computer-readable storage medium. The wastewater pipeline network monitoring method includes S1. a flow acquisition step and S2. a synchronous analysis step, analyzing the wastewater inflow Q of branch segment 1. in Wastewater outflow rate Q out The time synchronization between them, the optimal lag time ΔT; S3. Flow loss calculation steps, to make the sewage inflow Q in With wastewater outflow Q out Synchronize, and then calculate the flow loss Q based on the difference between the two time series. s =Q in -Q out S4. Fault confirmation steps, if the traffic loss Q s If the branch section is located outside the predetermined standard range, there may be a potential fault. This sewage pipe network monitoring method can detect potential seepage conditions in branch section 1, such as ruptures or gaps, and can also monitor the overall patency of the pipe in branch section 1. It facilitates the installation and maintenance of the monitoring system, enabling non-contact monitoring and maintenance, and allows for real-time detection and reporting, thus improving response speed.
