Parallel multi-channel jet vacuum pump

Abstract

The invention relates to a parallel multi-channel jet vacuum pump, and belongs to the technical field of injection pumps for pumping fluid through inertia of the pumped fluid. The parallel multi-channel 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 clamping plate and a right clamping plate which are attached to each other are arranged in the jet box, a plurality of jet nozzles which are parallel to one another are arranged between the left clamping plate and the right clamping plate, the inlet ends of the jet nozzles are provided with jet fluid inlet pipes which are parallel to the left clamping plate and the right clamping plate, and inlets of the jet fluid inlet pipes are communicated with an outlet of the submerged pump. The aperture of each jet nozzle ranges from 8 mm to 20 mm, the outlet end of each jet nozzle is opposite to the outlet of the jet box, the edge of the right clamping plate is provided with an air inlet pipe communicated with each jet nozzle, and the air inlet pipe is communicated with an outlet of the vacuum tank. The parallel multi-channel 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, 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.
