Downhole separate injection tubular column and separate layer water injection method
PendingCN121827761AInjection volume changesAdequate and accurate injection volumeFluid removalOil fieldDistributor
The invention relates to the technical field of oil field water injection wells, in particular to an underground separated injection pipe column and a separated layer water injection method, and aims to solve the problem that high-pressure layer injection of an existing separated injection pipe column is insufficient. The underground separate injection tubular column comprises a first packer, a water distributor, a second packer, a sliding sleeve, a screen pipe and a screwed plug which are sequentially arranged. The sliding sleeve is used for opening and closing the water injection hole; a first water injection layer is arranged between the first packer and the second packer, and a second water injection layer is arranged at the end, away from the first packer, of the second packer. The water distributor is used for injecting water into the first water injection layer, the water injection hole and the screen pipe are used for injecting water into the second water injection layer, and the oil layer pressure of the second water injection layer is higher than that of the first water injection layer; the plug is used for plugging the tail end of the tubular column. According to the underground separate injection tubular column, water injection is conducted on a low-pressure layer through the water distributor, water injection is conducted on a high-pressure layer through the water injection holes and the screen pipe in the mode that the water injection holes are opened through the sliding sleeve, and the problem that injection of the high-pressure layer is insufficient is avoided.

Bypass hydraulic control module reconfiguration structure
This utility model relates to a reconfigurable structure for a bypass hydraulic control module, comprising: a hydraulic control module, a cooling device, an oil tank, an unpressurized return oil pipe, and a pressurized return oil pipe; the hydraulic control module includes a proportional valve and a safety valve, the inlets of which are connected to the oil tank via a filter assembly, and the outlet of the proportional valve is connected to the inlet of the cooling device; the unpressurized return oil pipe connects the outlet of the safety valve to the oil tank; the pressurized return oil pipe connects the outlet of the cooling device to the oil tank. The beneficial effects of this utility model are: the oil exiting the proportional valve has hydraulic pressure, improving the cooling effect; simultaneously, an overpressure valve is connected between the inlet and outlet of the cooling device, allowing the oil to return to the oil tank from the overpressure valve when the oil pressure is too high, protecting the safe operation of the cooling device; the reserved ports of the hydraulic control module are readily available, allowing the cooling device to connect to these reserved ports, minimizing modification costs while achieving the cooling purpose.

Motor for electric working machine
PendingCN119519332Aavoid insufficient trafficavoid breakingMagnetic circuit stationary partsMechanical energy handlingMachineControl theory
The invention provides a motor for an electric working machine. A motor (20) for an electric working machine is provided with a cylindrical stator (22). The motor has a rotor (28) disposed on the inner peripheral side of the stator. The motor has a sensor substrate (30) provided at an axial end portion of the stator. The sensor substrate is provided with a substrate main body (31) which is positioned on the radial inner side of the stator when viewed from the axial direction. The sensor substrate has a leg portion (32) protruding radially outward from the substrate main body toward the stator. The stator is exposed in at least one of the circumferential directions of the leg parts. The motor is provided with a sensor (35) which is arranged on the leg part, is opposite to the rotor and is used for detecting rotation of the rotor. Therefore, the flow of the cooling air flowing in the motor can be increased.

ActiveCN224208735URelieve stressavoid insufficient trafficHollow article cleaningMarine engineeringStream flow
The utility model provides a floating type pressing box body water channel cleaning device, and relates to the technical field of box body water channel cleaning. A workbench is provided with a lifting assembly, a water outlet floating pressing assembly used for being connected with a box body inclined water nozzle in a sealed mode and a water inlet pressing connecting assembly used for being connected with a box body water inlet in a sealed mode; the lifting assembly is provided with a double-water-channel floating pressing assembly used for being connected with top openings of double water channels of the box body in a sealed mode, and the lifting assembly, the water outlet floating pressing assembly and the water inlet pressing connecting assembly define a box body containing area on the workbench. The double-water-channel floating pressing assembly automatically adapts to the height deviation of top openings of the double water channels through the floating structure, the height deviation of an inclined water nozzle can be compensated through the automatic adjusting capacity of the water outlet floating pressing assembly, the problem of insufficient sealing caused by traditional fixed pressing is solved, sealing compatibility is improved, reliable sealing is achieved, and the service life of the water outlet floating pressing assembly is prolonged. Insufficient pressure and flow of the cleaning fluid caused by leakage of the cleaning fluid are avoided, and the cleaning effect is guaranteed.
