Method for manufacturing silencer of split-type structure

Abstract

The invention relates to a method for manufacturing a large-capacity split-type silencer for controlling a pipeline in an air conditioner system. The method comprises the following steps: A10 using a stainless steel tube material for machining and forming into a silencing tube (1), A20 using a stainless steel material for machining and forming into an inlet end cover (2) and an outlet end cover (3), A30 enabling the inlet end cover (2) and the outlet end cover (3) to be fixed at the two ends of the silencing tube (1), and A40 forming a silencer assembly by welding the silencing tube (1), the inlet end cover (2) and the outlet end cover (3). According to the method for manufacturing the large-capacity split-type silencer, the stainless steel materials are used for machining and forming the silencing tube, a connecting tube, the inlet end cover and the outlet end cover, due to the fact that the copper plating method or the copper connector adding method is implemented, and welding between the silencer and an air conditioner pipeline part is facilitated. On the premise that the welding reliability of the silencer is ensured, the cost is reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and mainly relates to a manufacturing method of a large-capacity split muffler used for pipeline control in an air-conditioning system. Background technique [0002] The muffler is a kind of equipment used in the refrigeration system that can not only allow the airflow to pass through but also effectively reduce the noise. The muffler tube, intake pipe and outlet pipe of traditional mufflers are all made of copper pipes. The price of copper materials is high, which makes the cost of the muffler relatively high. Moreover, the muffler using copper materials often needs to go through the pickling process after welding. Cleaning surfaces has a big impact on the environment.

Problems solved by technology

Although such a structure saves part of the cost, in the manufacturing process at that time, the copper inlet / outlet pipe and the stainless steel muffler had to be welded. Since the welding characteristics of the copper material and the stainless steel material are very different, such as a simple implementation Welding, the process is more difficult, and the welding quality is not easy to guarantee

In addition, the welding temperature of stainless steel materials is relatively high, the thermal influence on the copper tube after welding is increased, and the material is also soft, which is easy to cause bruises in the subsequent manufacturing assembly and twists and turns. This problem is especially for large-capacity split structures. The muffler is more prominent
