Abstract

The invention relates to a jet vacuum pump and belongs to the technical problem of jet pumps utilizing inertia of pumped fluid to pump fluid. The jet vacuum pump comprises a submerged pump, a jet device and a vacuum tank, the jet device comprises a jet box with an outlet, a left clamp plate and a right clamp plate are oppositely arranged in the jet device, a jet nozzle is formed between the left clamp plate and the right clamp plate which are spaced by 8-20mm, an outlet end of the jet nozzle is arranged opposite to the outlet of the jet box, a jet fluid inlet tube vertical to the left clamp plate is arranged at the center of the left clamp plate, one end of the jet fluid inlet tube is communicated with an outlet of the submerged pump, the other end of the jet fluid inlet tube extends to the position of the jet nozzle, and an air inlet tube communicated with the jet nozzle is arranged at an edge of the right clamp plate and is communicated with a vacuum tank outlet. The jet vacuum pump has the advantages of high pressure-bearing capacity and good cleaning performance.

Description

technical field [0001] The invention relates to a negative pressure suction device, which belongs to the technical field of jet pumps for pumping fluid by utilizing the inertia of the pumped fluid. Background technique [0002] Jet vacuum pump is a device that generates, improves and maintains vacuum in a closed space by mechanical, physical, chemical or physical and chemical methods. It is generally composed of three parts: submersible pump, jet vacuum pump and pump box. It is widely used in decompression evaporation, crystallization, distillation, drying, decolorization, deodorization, vacuum transportation, etc. in petroleum, chemical, food, pharmaceutical, light industry, environmental protection and other industries. In the process. [0003] For the nozzles in existing jet vacuum pumps, if the nozzles are clogged, use a soft brush or toothpick to clean it and be very careful during the cleaning process, which may distort the orifice. In addition, the existing nozzles h...
