Problems solved by technology

The biggest disadvantage of this transmission method is: there are three bearings on the driving shaft, which increases the difficulty of processing and assembling the pump, and the disassembly and adjustment of the gears are also inconvenient; the overall structure is uneven, and the center of gravity of the pump is biased towards the side of the motor and the gearbox
[0007] At present, the existing vacuum pumps have poor operation stability, high noise and poor use effect.

Abstract

The invention discloses a low-noise vacuum pump. The low-noise vacuum pump comprises a rear cover, a pump body, a front cover, a support and a motor, wherein the rear cover, the pump body, the front cover, the support and the motor are sequentially and fixedly connected; a sight glass is arranged at the front end of the rear cover and is connected to the rear cover in a sealed mode; middle walls are arranged at the two ends of the pump body and are welded to the pump body, and two rotors are arranged in the pump body and are double-blade rotors; a shaft seal is arranged between the front cover and the support and is provided with an oil cup; a coupling is installed at the front end of the motor and is provided with two main shafts, shaft sleeves are arranged at the two ends of each main shaft and are connected to the middle walls in a clamped mode, and the main shafts are connected to the shaft sleeves in a rotating mode. The low-noise vacuum pump is compact in structure, stable in operation, low in noise, convenient to operate and good in sealing effect.

Description

technical field [0001] The invention relates to the technical field of a pump body, in particular to a low-noise vacuum pump. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries. [0003] With the development of vacuum applications, there are many kinds of vacuum pumps, whose pumping speed ranges from a few tenths of a liter per second to hundreds of thousands or millions of liters per second. As vacuum technology has wider and wider requiremen...
