The radiator gravel impact testing machine detects stabilityThe radiator gravel impact testing machine detects stability

1、 Overview:

Suitable for gravel impact testing of automotive radiators.

2、 Testing standards

QC/T468 "Automotive Radiators"

3、 Equipment testing and principle introduction

Principle:

Gravel or other media are placed in the feeding hopper, and the vibrating feeding device in the hopper sends the material to the feeding chute. The vacuum generated by the high-speed air below causes the medium to fall into the feeding chute. The medium is sucked into the nozzle and emitted onto the sample by the air injector. The medium collided with the sample and fell into the gravel box.

Experiment:

The test object is the radiator core part, which is sprayed continuously, usually only once.

The hardness of the quenched steel shot is 61HRC~65HRC, with sharp edges and an average diameter of 4mm~5m.

The specific experimental parameters are specified in Table 11.
