Final technical solution for Derrick gas cylinder airtightness testing machine

The gas cylinder sealing test machine is suitable for high-pressure gas sealing performance testing of compressed hydrogen plastic inner carbon fiber fully wrapped gas cylinders for vehicles, compressed hydrogen aluminum inner carbon fiber fully wrapped gas cylinders for vehicles, gaseous hydrogen road vehicle fuel gas cylinders and other gas cylinders and pressure vessels. This machine has the characteristics of automated and programmed testing process, easy operation, and high safety level. Suitable for gas cylinder production enterprises, scientific research and testing institutions to carry out relevant testing and research work.

Functional purpose

In non-metallic high-pressure vessels、Our company has a high market share in the pipeline fieldMore than 90% of users are using meThe company's product, this system equipment, is already a mature and standardized product of our company.

comply withIn addition to the requirements of GB/T 12137-2015 "Test Method for Gas Cylinder Airtightness" and T/CATSI 02007-2020 "Compressed Hydrogen Plastic Inner Cylinder Carbon Fiber Fully Wrapped Gas Cylinder for Vehicles"，Also meets the requirements of Non Metallic Composite Pipes for Petroleum and Natural Gas Industry 第Part 2: Requirements of relevant standards such as SY/T6662.2, SY/T6794, and API 15S for flexible composite high-pressure conveying pipes.

IIdesignaccording to

threeDesign principles

This system can detect the sealing of the pipeline when it is filled with gas (water bubbles and specified pressure drop), and quickly display the pressure drop and pipeline leakage location. This setThe system adopts an air driven air pumptoPressurize gases such as nitrogen toGas cylinder supply needsThe pressure.Gas cylinder placementInside a dedicated water tank，Close the water tank after filling it with water.System forInflate the gas cylinder, achieveAfter setting the pressure value, rely on the pressure inside the water tankHDUnderwater camera to observe for bubbles.smearsoapThe water detection method does not require filling the water tank with water,rely oncameraorHuman direct observation is sufficient.

3.1The maximum pressure of the pressure host can reach80MPa， The tooling can meet the maximum cylinder size for long-term testing.

3.2The equipment has high reliability. The longest single experiment in this experiment needs to be conducted500 hours (maximum designed test time of 500 hours), no pressurization or depressurization faults are allowed in a single test

3.3 pressure reliefThe speed can be within a certain rangeinsideFree setting

3.4Our company adopts gas-liquid pressurization method and60000/1Pressure control methodIt can meet the requirements of GB/T 12137-2015 "Gas Cylinder Airtightness Test Method" at 70MPa ± 1%, and at the same time, it can use pressure reduction and control methods to meet the requirements of T/CATSI 02007-2020 "Vehicle Compressed Hydrogen Plastic Inner Cylinder Carbon Fiber Fully Wrapped Gas Cylinder" for low pressure sealing testing at 0-0.7MPa.
