Abstract

The invention discloses a withstand test system and a method for a microchannel tube. The withstand test system comprises an air compressor which provides working pressure, a water pressure system which provides working water flow and performs water pressure collection and control, and a withstand test machine which is mainly composed of a high-pressure gas-driven liquid pump, a high-pressure microchannel tube connector, a pressure plugging device and a working table. The method aims to test pressure endurance capability of a microchannel flat tube. The pressure endurance capability is tested through the method of sealing one end of the microchannel flat tube and injecting high-pressure water into the other end. By adopting the withstand test system and the method, a withstand test on relatively soft metal tubes made of copper, aluminium and the like, and on tubes with circular cross sections and non-circular cross sections and with small rigidity can be achieved; and in addition, with adoption of the withstand test system, a pressure blasting test and a pressure maintenance test can be achieved on both microchannel extruded tubes and folded tubes, especially tabular cross-section tubes and particularly tubes of which cross sections are provided with vesicular structures and singular pore structures.

Description

technical field [0001] The invention relates to a pressure-resistant test system for micro-channel tubes. The device can realize pressure-holding tests and burst tests for micro-channel tubes of various specifications, especially for micro-channel flat tubes with porous structures and singular pore structures in the cross-section of the tubes. pressure test, and the present invention also relates to a pressure test method for microchannel tubes.
