Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a test device and method for a passenger car brake hose. Background technique [0002] Brake hose is an important part of the braking system of rail vehicles. The quality of brake hose maintenance is directly related to the quality of the company's passenger car maintenance and the safety of passengers' lives and property. , After the brake hose is overhauled and overhauled, the wind pressure test should be carried out first, and then the water pressure test should be carried out. The specific operation is to install the brake hose that has passed the inspection on the brake hose test bench, first conduct a (600±10) kPa wind pressure test, and keep the pressure for 5 minutes. There must be no leakage or bubbling at the joints of the brake hose Phenomenon, the test time is measured by employees using a stopwatch, and the test wind pressure is displayed by th...
