Device for testing wind erosion of automotive catalytic converter liner products

Abstract

The invention relates to a device for testing wind erosion of automotive catalytic converter liner products. A driving motor is fixedly mounted at the bottom of a frame body, wherein a driving wheel is mounted at an output shaft of the driving motor; a transverse plate is arranged at the upper part of the frame body; a driven and the driving wheel are in winding connection with each other througha belt; a rotating disc is fixedly mounted on the outer side of the driven wheel; clamping parts are arranged on the surface of the outer end of the rotating disc; outer clamping plates are fixedly mounted on the end surface of the rotating disc; inner clamping plates are connected with the outer clamping plates through fixing bolts; test liners are mounted between the outer clamping plates and the inner clamping plates; an air nozzle passes through a positioning pipe and is fixed by a positioning bolt; an air compressor and the driving motor are connected to a control box through lead wires.The device for testing the wind erosion of the automotive catalytic converter liner products is low in testing cost and short in testing period, and is capable of adjusting liner clamping density, transversely comparing multiple samples and quantifying the wind erosion resistance.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a wind erosion test equipment device for an automobile catalytic converter liner product. Background technique [0002] Catalytic converter gasket products are sheet-like composite materials made of ceramic fibers, expandable vermiculite and organic binders. They are widely used in exhaust gas aftertreatment systems of internal combustion engines to wrap and fix catalyst porous carriers. The porous carrier Generally, it has a relatively large specific surface area and can be coated with precious metals or functional coatings. It plays a role in the chemical reaction with harmful components in the exhaust gas in the entire exhaust system. This function is also the main function of the exhaust system. It can be seen that the gasket product that wraps and fixes the porous carrier is also a key component in the exhaust system. [0003] In the actual application environment, the edge of the ca...

AI Technical Summary

Problems solved by technology

[0005] 1. Prototype and testing costs are high

Including the cost of prototype manufacturing including catalyst carrier and assembly welding, and the engine bench must be used for testing;

[0006] 2. Long test period

Since the assembly experiment needs to simulate the actual engine operating conditions, and the exhaust flow of the engine is limited by its own universal characteristics, it cannot be adjusted freely, and the test conditions cannot be deteriorated to speed up the test process and reduce the test time;

[0007] 3. It is impossible to set the compression density of the liner at the same time. Since the current assembly-level tests use the actual product as the body of the test prototype, a very important factor affecting the blowing erosion performance of the liner is the tightness of the liner being compressed , if the actual sample is used as the research object, limited by the actual parts, generally only one degree of compression can be tested at a time;

[0008] 4. It is impossible to carry out horizontal comparison of multi-model liner products

As described above, only one model of sample can be carried at a time, and multiple samples cannot be compared horizontally, helping users and designers to quickly determine the design parameters of the best model

[0009] Unable to quantify how much the liner is blown away, in current tests it always occurs in the catalyst assembly, after dissection it is almost impossible to quantify the mass or volume blown away
