The invention relates to an adjustable jet vacuum pump with the high pressure bearing capacity and good cleaning performance, and belongs to the technical field of jetting pumps used for pumping fluid through the inertia of the pumped fluid. The adjustable jet vacuum pump comprises an immersible pump, a jet device and a vacuum tank. The jet device comprises a jet box with an outlet. A left clamping plate and a right clamping plate opposite to the left clamping plate are arranged in the jet box. A jet nozzle is formed between the left clamping plate and the right clamping plate. The interval between the left clamping plate and the right clamping plate ranges from 8 mm to 20 mm. The outlet end of the jet nozzle is arranged opposite to the outlet of the jet box. The inlet end of the jet nozzle is provided with a jet fluid inlet pipe which is parallel to the left clamping plate and the right clamping plate. The jet fluid inlet pipe communicates with an outlet of the immersible pump. An air intake pipe communicating with the outlet end of the jet nozzle is arranged on the edge of the right clamping plate, and communicates with an outlet of the vacuum tank. A bolt is arranged between the left clamping plate and the right clamping plate in a penetrating mode. The two ends of the bolt are in screwed connection with the left clamping plate and the right clamping plate correspondingly, and extend out of the left clamping plate and the right clamping plate in a suspended mode. The adjustable jet vacuum pump has the advantages that the pressure bearing capacity is high, the cleaning performance is good, and the size of the nozzle can be adjusted.
