Damping and noise-proof roots flowmeter

Abstract

The invention provides a damping and noise-proof roots flowmeter, and belongs to the technical field of flowmeters. The damping and noise-proof roots flowmeter comprises a display unit assembly, a front end cover is arranged at the rear part of the display unit assembly, an oil throwing sheet is arranged in the front end cover, a magnetic coupling connector is mounted in the front end cover, the rear part of the magnetic coupling connector is connected with a bearing, the bearing is connected to the upper portion of a front wall plate in a sleeving mode, one end of the bearing is connected with a roots assembly, the roots assembly is installed in the shell, an upper fixing plate is arranged on the upper portion of the shell, and a lower fixing plate is installed at the bottom of the shell. Absorption and buffering of transverse and vertical stress of the flowmeter are achieved through upper buffering plates arranged on the four sides of the interior of the upper fixing plate and the vertical buffering springs between the upper internal connection threads and the lower internal connection threads, so that the effects of fully reducing vibration in operation, reducing noise pollution and prolonging the service life are achieved; and handles are arranged on the two sides of the shell, so that a user can conveniently lift the flow meter by hand and conveniently move and use the flow meter.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a shock-absorbing and noise-proof waist wheel flowmeter. Background technique [0002] The gas lobe flowmeter is a volumetric instrument that measures the flow of gas medium in a closed pipeline. With its high precision, wide range, small size, light weight, convenient installation and maintenance, reliable use and durable service life, it is widely used in the trade measurement of urban gas, especially for government agencies, schools, enterprises, institutions, Trade measurement for large gas consumers such as hotels and restaurants. It can also be used in the main metering, gas distribution station, main gas supply station and other occasions of various industrial raw gas. [0003] During the operation of the gas waist wheel flowmeter, due to its large volume, heavy pressure loss, etc., it will cause large vibrations, generate a lot of noise during operation, and the flow...

AI Technical Summary

Problems solved by technology

First, the solution only absorbs shock in one direction, and the anti-shock effect needs to be further strengthened; second, there is no special auxiliary device for moving the flowmeter, and the equipment is not convenient enough to move
