Abstract

The invention discloses a test method and a test device. The liquid supply assembly of the test device comprises a rainwater nozzle and a water spray nozzle which share a touch screen, a controller, awater supply pipe, a water tank, a multistage pump, a frequency converter, a flow sensor and a pressure sensor, that is, there is no need to separately provide touch screens, controllers, water supply pipes, water tanks, multistage pumps, frequency converters, flow sensors and pressure sensors for the rainwater nozzle and water spray nozzle. Moreover, the rainwater nozzle and the water spray nozzle supply water to the same test box to perform a waterproof test on a test piece. Thus, there is no need to separately provide the test boxes, thereby reducing the cost of the rainwater test and thewater spray test of an explosion-proof product to a certain extent.

Description

technical field [0001] The invention relates to the field of waterproof test technology, in particular to a test device and a test method. Background technique [0002] Explosion-proof products need to undergo rain test and water spray test before leaving the factory to ensure that the explosion-proof products meet the requirements, will not be damaged during daily use, and can keep working normally. [0003] In the prior art, the rain test and the water spray test of the explosion-proof products need to set up test benches separately, so that the cost of the rain test and the water spray test of the explosion-proof products is relatively increased. [0004] Therefore, how to reduce the cost of rain test and water spray test for explosion-proof products has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a test device to reduce the cost of rain test and water s...
