Jet pump for oil-water separation

The utility model relates to the technical field of oil-water separation, in particular to an injection pump for oil-water separation, which comprises a nozzle pipe, an internal thread three-way pipe,a diffusion pipe and a bushing, the nozzle pipe, the diffusion pipe and the bushing are connected to the internal thread three-way pipe in a threaded mode, and a funnel-shaped high-pressure inlet channel is arranged in the nozzle pipe. The end, screwed into the internal thread three-way pipe, of the nozzle pipe is conical, a straight channel type mixed flow channel and a funnel-shaped expansion flow channel are formed in the diffusion pipe, and the end, screwed into the internal thread three-way pipe, of the diffusion pipe and the end, screwed into the internal thread three-way pipe, of the diffusion pipe are conical. Through the design, the high-pressure airflow entering speed is increased, the stirring and shredding capacities of liquid entering the bubble generator are stronger, underthe driving of the same li
