Adjustable jet vacuum pump

Abstract

The invention relates to an adjustable jet vacuum pump and belongs to the technical problem of jet pumps utilizing inertia of pumped fluid to pump fluid. The adjustable 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 is arranged at an inlet end of the jet nozzle and is parallel to the left clamp plate and the right clamp plate, an inlet of the jet fluid inlet tube is communicated with an outlet of the submerged pump, an air inlet tube communicated with the outlet end of the jet nozzle is arranged at an edge of the right clamp plate and is communicated with a vacuum tank outlet, a bolt is penetratingly arranged between the left clamp plate and the right clamp plate, and two ends of the bolt are in screw joint with the left clamp plate and the right clamp plate respectively and extend out of the left clamp plate and the right clamp plate in suspension respectively. The adjustable jet vacuum pump has the advantages of high pressure-bearing capacity, good cleaning performance and adjustability in size of the jet nozzle.

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, ejector, 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.
