Abstract

The invention discloses a static pressure test system for a rail transit product, comprising a test box (5). The test box (5) is provided with a preset rail transit product that needs to be subjectedto a static pressure test. The test box (5) is connected with a pressurizing system configured to input air with a preset pressure to the inside of the test box (5). The test box (5) is in communication with a pressure relief system for discharging the air inside the test box (5) to decompress the air pressure inside the test box (5). A test air pressure control unit (7) is respectively connectedto the pressurizing system and the pressure relief system for respectively transmitting control signals to the pressurizing system and the pressure relief system so as to correspondingly control the opening and closing states of the pressurizing system and the pressure relief system. According to the static pressure test system for the rail transit product, the air pressure applied to the productcan be automatically adjusted, the labor cost of the test is saved, and the loading precision of the load during static pressure intensity testing of the product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of product testing, in particular to a static pressure testing system for rail transit products. Background technique [0002] At present, with the development of my country's rail transit technology, product models are diversified, and the safety and reliability of rail transit are much higher than other modes of transportation. It involves the safe travel of millions of passengers, so the load environment of products is becoming more and more stringent. , the product needs to meet the specified strength requirements. Therefore, it is necessary to conduct static pressure strength tests on rail transit products. [0003] In the traditional static pressure strength test, the loading method adopted is a manual operation control method, and the air pressure applied to the product is manually adjusted, which not only increases the labor cost of the test, but also increases the labor intensity of the test personn...
