Jet vacuum pump with high bearing pressure and good cleaning performance

Abstract

The invention relates to a jet vacuum pump with high bearing pressure and good cleaning performance, and belongs to the technical field of injection pumps utilizing the inertia of pumped fluid for pumping the fluid. 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 to each other are arranged in the jet box. A jet nozzle is formed between the left clamping plate and the right clamping plate. The distance 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 opposite to the outlet of the jet box. A jet liquid inlet pipe perpendicular to the left clamping plate is arranged 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 nozzle. An air inlet pipe communicating with the jet nozzle is arranged on the edge of the right clamping plate and communicates with an outlet of the vacuum tank. The jet vacuum pump has the beneficial effects 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.
