Abstract

The invention belongs to the technical field of rubber performance testing, and especially relates to a volume expansion system for rubber hose detection. The system includes a control system and a measuring device connected with the control system. The control system comprises a PLC controller, a driving device, a hydraulic servo valve, a high pressure sensor and an A / D converter. The PLC controller is respectively connected with the driving device and the A / D converter; the driving device is connected with the hydraulic servo valve; the hydraulic servo valve is connected with the measuring device; and the measuring device is connected to the A / D converter. The invention has the beneficial effects that: the system is used for test of the volume expansion of an automobile brake hose, realizes the automatic control of the equipment and simplifies the structure of the equipment.

Description

technical field [0001] The invention belongs to the technical field of rubber performance testing, in particular to a volume expansion system for testing rubber hoses. Background technique [0002] With the rapid development of my country's automobile industry, people's requirements for the safety of automobiles, especially the prevention of accidents, are becoming more and more stringent. As one of the active safety components of automobiles, the quality of automobile hydraulic brake hoses that transmit braking power is becoming more and more important. . The quality of the brake hose will directly affect the safety and reliability of the vehicle. When a car traveling at high speed brakes in an emergency, the hydraulic brake hose suddenly bursts and the consequences are unimaginable. [0003] For rubber brake hoses, the inner volume expansion is one of its main performance parameters. When a brake hose is subjected to a specified internal pressure, it expands in volume. ...
