Cylinder hydrostatic test machine –Computer control model


Suncenter's Cylinder Hydrostatic Testing Machine, specifically designed for gas cylinders, offers seamless testing for a variety of steel cylinders.

This includes nitrogen cylinders, argon helium cylinders, oxygen cylinders, hydrogen cylinders, carbon dioxide cylinders, and LPG/LNG/CNG

winding bottles, among others. The equipment, computer-controlled and featuring an HP printer for direct test report printing, employs a double

water jacket for oxygen bottles and other cylinders. It is widely utilized in testing station cylinder jacket methods for hydrostatic test evaluations.

This machine is primarily employed for cylinder pressure testing and determining the gas cylinder volume residual deformation rate. The working principle

involves placing the cylinder into a water jacket and pressurizing it using a high-pressure pump. The system automatically dwells at the set pressure,

conducting a pressure test on the cylinder. Simultaneously, the cylinder volume expands under the test pressure, squeezing water from the water jacket into

a measuring cup to assess cylinder volume deformation.

The water collected during the test is transferred to a PC via the water collection system. After the cylinder is relieved of pressure, the elastic deformation disappears,

and the water flows back from the measuring cup to the water jacket. However, the remaining water in the measuring cup exceeds the initial volume before boosting

the cylinder. This excess water volume represents the gas cylinder volume residual deformation.

The gas cylinder volume residual deformation rate is then calculated as the ratio of the test gas cylinder volume residual deformation to the total deformation.

This comprehensive testing system ensures accurate and reliable evaluation of cylinder integrity, making it an indispensable tool for various industries.
