Embodiment 1

[0084] The modular design method of the exhaust muffler includes the following steps:

[0085] S1. Determine the diameter of the inner tube and the diameter of the outer tube according to the diameter of the engine exhaust port;

[0086] S2. Determine the diameter of the outer shell according to the diameter and expansion ratio of the inner cannula, and the diameter of the entrance resistance cavity and the diameter of the exit resistance cavity inside the shell;

[0087] S3. Determine the resistive unit according to the noise reduction requirement;

[0088] S4. Assembling the inner tube, the outer tube, the shell and the resistive unit together to obtain an exhaust muffler.

[0089] For example, the diameter of the exhaust port of a certain engine is 71mm, the peak frequency of exhaust noise is 800Hz, and the sub-peak frequency of exhaust noise is 1600Hz, and the noise reduction of the resistive unit is required to be 15dB. Assume that according to the cluster analysis result...

Abstract

The invention relates to the technical field of exhaust silencers of diesel generating sets, in particular to an exhaust silencer modular design method. The method comprises the following steps of S1, determining the diameter of an inner insertion pipe and the diameter of an outer insertion pipe according to the diameter of a smoke outlet of an engine; S2, determining the diameter of a shell and the diameter of an inlet resistant cavity and the diameter of an outlet resistant cavity in the shell according to the diameter of the inner insertion pipe and the expansion ratio; S3, determining a resistive unit according to a noise reduction requirement; and S4, mutually assembling the inner insertion pipe, the outer insertion pipe, the shell and the resistive unit, and obtaining an exhaust silencer. According to the exhaust silencer modular design method, the problem that an existing exhaust silencer is low in generalization degree can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of exhaust mufflers for diesel generator sets, in particular to a modular design method for exhaust mufflers. Background technique [0002] In the diesel generator set industry, exhaust mufflers are usually customized according to the type of engine, but there are many types and brands of engines, and the diameters of exhaust outlets and flange structures are different, resulting in many types of customized exhaust mufflers with a wide range and a high degree of generalization. Extremely low, resulting in long delivery cycle, error-prone workshop and other problems. However, some customers do not have high requirements for exhaust mufflers, but pay more attention to factors such as simple installation, high reliability, and short delivery time. Therefore, it is imminent to improve the modularization and generalization of exhaust mufflers to meet the increasingly shortened delivery time requirements of the m...
