Three-dimensional rotary-vane vacuum pump

Abstract

The invention belongs to the technical field of vacuum pumps, and particularly relates to a three-dimensional rotary-vane vacuum pump which comprises a vacuum pump body and a heat dissipation assembly, a support is fixedly connected to one side of the vacuum pump body, the heat dissipation assembly is fixedly connected to the support and comprises a box body and a box cover which are arranged in a matched mode, and heat dissipation fins are arranged in an inner cavity of the box body. Liquid outlets of the cooling fins are communicated with a cavity of cooling liquid in a shell of the vacuum pump body through a backflow pipe, a micro water pump is connected to the backflow pipe in series, and atomizing nozzles evenly distributed on the inner wall of the box body are communicated with a water inlet pipe. Compared with an existing water heat absorption transduction cooling mode, the heat dissipation assembly utilizes a water mist evaporation heat absorption cooling mode, the heat dissipation cooling effect is better, the water mist evaporation heat absorption cooling speed is high, the efficiency is high, cooling and heat dissipation treatment can be rapidly conducted in a short time, and it is ensured that the vacuum pump can stably operate for a long time; damage of high temperature to the vacuum pump is reduced, and the service life of the vacuum pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a three-dimensional rotary vane vacuum pump. Background technique [0002] The rotary vane vacuum pump defines that the eccentrically installed rotor in the pump is tangent to the fixed surface of the stator, and two (or more) rotary vanes slide in the rotor slot (usually radially) and contact the inner wall of the stator, dividing the pump cavity into several A variable volume rotary variable volume vacuum pump. Usually, the gap between the rotary vane and the pump cavity is sealed with oil, so the rotary vane vacuum pump is generally an oil-sealed mechanical vacuum pump. [0003] The rotary vane vacuum pump is the most widely used vacuum pump body among the existing vacuum pumps. It has the advantages of simple structure, low manufacturing precision and compact structure. However, the existing rotary vane vacuum pump drives the rotary vane to rotate through the eccentrica...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional rotary vane vacuum pump, which solves the problem that the rotary vane always rubs against the inner wall of the pump chamber during the rotation process, which will generate a lot of heat, and the long-term high temperature will affect the pump body. The service life is not convenient for daily use
