Operating method of multi-channel jet vacuum pump

Abstract

The invention relates to an operating method of a multi-channel jet vacuum pump. The multi-channel jet vacuum pump comprises an immersible pump, a jet device and a vacuum tank. The jet device comprises a jet box provided with an outlet. A left clamping plate and a right clamping plate which are mutually attached are arranged in the jet box. A jet liquid inlet pipe which communicates with the left clamping plate and is perpendicular to the left clamping plate is arranged in the center of the left clamping plate. The inlet end of the jet liquid inlet pipe communicates with an outlet of the immersible pump. A plurality of jet nozzles communicating with the jet liquid inlet pipe are arranged between the left clamping plate and the right clamping plate and evenly distributed along the center of the jet liquid inlet pipe in the circumferential direction. The diameter of each jet nozzle is 8 mm-20 mm. The outlet end of each jet nozzle is opposite to an outlet of the jet box. An air inlet pipe communicating with the jet nozzles is arranged on the edge of the right clamping plate. The air inlet pipe communicates with an outlet of the vacuum tank. The multi-channel jet vacuum pump has the advantages that the bearing pressure is high, and the cleaning performance is good.

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.
