QSW-2 CNG external water pressure testing system

Description

Performance requirements

• Touch screen man-machine interface control;
• Gas cylinder externalwater pressure testing with water jacket inflatable rubber ring type sealing device;
• Cylindermouth use internal pressure sealed threaded joint;
• Configure the pressure fine-tuning mechanism to effectively calibrate the equipment;
• It adoptsthe weighing method to automatically read the weight of the empty bottle, the weight of the bottle plus water, automatically calculate the volume;
• It adopts principle of the tanker to inject water, the operation is convenient, and the water injection efficiency is high;
• It adopts computer to automatically control the water pressure test of the gas cylinder;
• Automatically collect water quantity (deformation value), pressure and time data sets and save them;
• Dynamically display time/water volume, time/pressure, water volume/pressure curve during testing process.
• Automatically calculate the residual deformation rate of the testedcylinder and determine the experimental results, and automatically save all test data;
• Automatically generate and output waterpressure testing report (EXCEL format);
• The testingdata is permanently stored. At any time, the test process, results, and re-generation of test reports can be queried according to the relevant CNG cylinder data (such as testing date, CNG cylinder number, batch number, etc.);
• Computer remote control and maintenance;

The external water pressure testing machine for CNG cylinders is designed and manufactured according to the national standard GB/T9251-2011 “Cylinder water pressure test method” and the US DOT standard (reference), which can conduct external water pressure tests on cylinders of different specifications.
