Abstract

The invention relates to a working method of a jet vacuum pump and belongs to the technical field of jet pumps for pumping fluids through inertia of pumped fluids. The 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 which are opposite are disposed in the jet box; a jet flow jet nozzle is formed between the left clamping plate and the right clamping plate; the space between the left clamping plate and the right clamping plate is 8-20 mm; the outlet end of the jet flow jet nozzle is opposite to the outlet of the jet box; a jet liquid inlet pipe perpendicular to the left clamping plate is disposed in the center of the left clamping plate; one end of the jet liquid inlet pipe communicates with an outlet of the immersible pump, and the other end of the jet liquid inlet pipe extends to the jet flow jet nozzle; air inlet pipes communicating with the jet flow jet nozzle are disposed at the edges of the right clamping plate; and the air inlet pipes communicate with an outlet of the vacuum tank. The jet vacuum pump has the advantages of being high in bearing pressure and good in 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...
