Device for detecting air tightness of dissipative muffler

Abstract

The invention discloses a device for detecting the air tightness of a dissipative muffler. The device comprises an engine case, a working cavity and a sliding valve, wherein a rotating roll is arranged on a side surface of the sliding valve; the periphery of the top surface of the engine case is bulged upward; screw holes are formed in the bulged part; a cooling water cover is arranged above the engine case; through holes are formed in the cooling water cover; bolts penetrate through the through holes and are inserted into the screw holes; a plurality of baffle plates are arranged under the cooling water cover; cavities are formed in the baffle plates; springs and supporting plates are arranged in the cavities; the lower parts of the supporting plates are connected with bases; a water inlet and a water outlet are respectively mounted on two mutually parallel side surfaces of the cooling water cover; when the cooling water is mounted on the engine case, the bottoms of the baffle plates are in contact with the engine case, and the baffle plates are perpendicular to side surfaces of the bulged part; and the baffle plates are parallel to one another, and every two adjacent baffle plates are connected onto the different side surfaces of the bulged part. The device not only is convenient to clean, but also has the advantage that the engine case assembly is prevented from being repeatedly dismounted from and mounted in a screw rod compressor, so that the working strength of operating personnel can be reduced and the service life of the engine case can be prolonged.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a device for checking the airtightness of a resistive muffler. Background technique [0002] Air compressors, also known as air compressors, are general-purpose machinery in modern industries and the core equipment of pneumatic systems. Air compressors convert the mechanical energy of electric motors or diesel engines into gas pressure energy, and increase the gas pressure or transport gas by compressing the gas. Purpose. Air compressors are widely used in steel, electric power, metallurgy, petroleum, mining, automobile industry, aerospace and infrastructure and other fields. [0003] There are many types of air compressors, mainly divided into two categories: positive displacement air compressors and speed air compressors. Among them, the positive displacement air compressor has a working chamber whose volume can change periodically. The positive displacement air compressor main...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is aimed at the defects of the casing assembly of the traditional screw air compressor. , not only very inconvenient, but also frequently disassembling the casing assembly from the screw air compressor not only increases the work intensity of the operator, but also reduces the service life of the casing
