Automatic hydrostatic test control system using air-bottle outer measuring method

Abstract

The invention relates to an automatic hydrostatic test control system using an air-bottle outer measuring method, comprising a hydrostatic test system, a control platform and a matched auxiliary system. The hydrostatic test system is used for the hydrostatic test of a tested air bottle and comprises a booster pump, a water jacket, a measuring cup, an electronic scale and a recycle pump, the auxiliary system comprises an automatic feeding device, a lifting sealing device and an automatic discharging device, wherein the automatic feeding device feeds the tested air bottle into a test position, the lifting sealing device loads tested air bottle in the water jacket or pulls the tested air bottle out of the water jacket, and the automatic discharging device conveys the tested air bottle out of the test position. The invention realizes the automatic operation of a hydrostatic test process, realizes the real-time and automatic detection and control of the test process, further lightens the labor intensity of operators, improves the detection efficiency and the detection accuracy and can realize the automatic operation of all auxiliary processes of the hydrostatic test by using the air-bottle outer measuring method.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel detection, and in particular relates to an automatic control system for a hydraulic test of a gas cylinder external measurement method. Background technique [0002] Gas storage cylinder is a pressure vessel widely used in various fields such as industry, agriculture, military affairs, science and technology, and daily life. The quality of the cylinder is directly related to the safety of people and property. Therefore, during the manufacturing process and trial period of steel cylinders, testing must be carried out according to national standards, and hydrostatic testing is a mandatory testing method. The purpose of the hydrostatic test is: first, to check the compressive strength of the pressure-bearing parts; second, to measure whether the volume residual deformation rate and volume total deformation value meet the requirements of the national standard, so as to judge the quality of th...
