The gravel impact tester mainly simulates the actual driving conditions of the car. The coated steel shot or gravel on individual parts of the body is sprayed by compressed air at a certain angle onto the coating, which is often subjected to heavy weight such as sliding materials , road gravel, etc. The impact of objects, so that the surface of the composite layer is damaged, is a test equipment independently developed and produced by our company Shanghai QINSUN Precision Electromechanical Technology Co., Ltd., with high cost performance and complete after-sales service . The degree of coating damage depends on the cascade of spray angle and spray pressure, and the coating will peel off in a single layer, several layers, or even all of them. The impact of crushed stone, the quality of steel shots or crushed stone, the duration of the impact and the testing equipment not only cause the loss of the decorative effect of the coating, but also affectedn also the curing conditions of the coating; all safety devices (emergency stop, protective door switch, etc.) are connected to the safety relay, and the intermediate double-loop relay contacts the common end; and the relay can only be reset manually, and automatic reset is prohibited.
Function introduction:
