Flexible rod super long stroke pumping unit

This invention discloses a flexible rod ultra-long stroke pumping unit, belonging to the technical field of pumping units. The flexible rod ultra-long stroke pumping unit includes a support frame, with an upper platform assembly at the top of the support frame. A cage ladder is fixedly connected to the outer side of the support frame. A drive device is located at the top of the upper platform assembly, and the drive device is connected to a flexible rod. A sucker plug is connected to the end of the flexible rod. A centering wheel assembly is located on the side of the support frame away from the cage ladder, through which the flexible rod passes. The drive device is also connected to a counterweight balancing mechanism. The flexible rod ultra-long stroke pumping unit achieves the reciprocating motion of the sucker rod by winding and releasing the flexible rod on a drum. Compared with various newly developed beamless pumping units on the market, it features a simple structure, small footprint, an ultra-long stroke of 18 meters, low stroke rate, and convenient maintenance.

An aeroponic cultivation apparatus

ActiveCN224611517Upromote emptyingThe breeding rate is obvious
This invention provides an aeroponic cultivation device, comprising a magnetic frame and a magnetic soft membrane shell disposed on the surface of the magnetic frame. The magnetic frame houses an electrical box, a nutrient solution tank, a water storage tank, a high-pressure water pump, a sterilization and filtration device, at least one atomizing box with a planting rack, at least one seedling rack, and growth lights positioned relative to the planting rack and seedling rack. The nutrient solution tank, water storage tank, high-pressure water pump, and atomizing box are sequentially connected via flexible hoses. An atomizing nozzle is located at the outlet of the hose connecting to the atomizing box. The bottom plate of the atomizing box extends obliquely downwards from one side, and its upper surface is recessed with a guide groove and a liquid collection port located at the end of the guide groove. The liquid collection port is connected to the inlet of the sterilization and filtration device via a return pipe, and the outlet of the sterilization and filtration device is connected to the water storage tank. This aeroponic cultivation device offers the advantages of stable nutrient solution circulation and ease of maintenance.

Screw pump, oil production system, oil production method, storage medium, and electronic device

This invention provides a screw pump, an oil production system, an oil production method, a storage medium, and electronic equipment, belonging to the field of petroleum extraction technology. The screw pump includes a stator and a rotor. The rotor has an arc-shaped structure that is large at both ends and small in the middle, and is symmetrical. The stator also has an arc-shaped structure that is small at both ends and large in the middle, and is symmetrical. The rotor is located inside the stator. The inner surface of the stator and the outer surface of the rotor have the same curvature. Both the inner surface of the stator and the outer surface of the rotor are threaded surfaces. The threaded surfaces of the stator and rotor cooperate with each other to allow the rotor to rotate within the stator, forming a pump cavity between the stator and the rotor. The pump has low overall leakage, high efficiency, and high head. The symmetrical pump cavity formed between the stator and the rotor results in almost equal flow rates in each cavity, leading to uniform filling of the symmetrical pump cavities. This results in symmetrical force on the pump body, high overall wear resistance, and a long service life.

Positive and negative adjustment submersible screw pump

The invention relates to a forward and reverse adjustment submersible screw pump which comprises a shell, and a driving part, a stator and rotor assembly, an adjusting shaft, an adjuster and a limiter which are arranged in the shell. The driving part is used for providing rotation driving force for the rotor, so that the rotor and the stator rotate relatively, and oil extraction is achieved. The screw pump shell is positioned through the oil pumping pipe fixed underground, so that the rotor can be positioned through the limiting stopper, in addition, the adjuster can convert rotary motion carried out together with the adjusting shaft into rotary motion independent of the adjusting shaft, the adjuster is in threaded fit with the adjusting shaft, and the adjusting shaft is in threaded fit with the adjusting shaft. Axial displacement can occur between the adjuster and the adjusting shaft, so that the gap between the stator and the rotor is accurately adjusted.

An intermittent control method and system based on edge computing

This invention relates to the field of oil well intermittent control technology, and particularly to an intermittent control method based on edge computing. The steps are as follows: S101: Set the oil well information transmission path and generate basic oil well analysis data; S102: Perform edge computing through the wellhead RTU based on the basic data to complete information extraction and analysis, generating single-well production, daily power consumption, dynamic fluid level, and system efficiency; S103: Set parameter constraints online; S104: Perform online discrimination based on the parameter constraints and correct the operating cycle T, start-up time RT, and shutdown time ST; S105: Automatically set the optimal operating cycle T, start-up time RT, and shutdown time ST on each wellhead RTU; S106: After setting the optimal operating cycle T, start-up time RT, and shutdown time ST, automatically display the data in tables and experimental data curves. This invention improves the safety, reliability, and stability of intelligent intermittent oil well operation, significantly increases mechanical production efficiency, and reduces costs.
