The test machine is suitable for cylinders as below:
Capacity: up to 130L; Length: from 90cm to 200cm
Diameter: from 110mm to 410mm
Application:
Hydraulic volumetric expansion testing for CNG cylinder, LPG cylinder, fire extinguishers, seamless cylinder, breathing cylinder, pressure accumulator, steel cylinder, (Direct volumetric expansion testing and water jacket testing are available)
The machine is mainly used for cylinder pressure test and achievement of gas cylinder volume residual deformation rate.
Key features and advantages:
- Control mode: PC control
- Software specification and display ((include: pressure rate, drop pressure detection, show test time, save data for each cylinder, P-T diagram for each cylinder from beginning to end of the test).
- Real-time monitoring as well as data recorded on high-speed sampling cards and also testing curves printing
- Alarming at due time bursting and due point recording
- A variety of tooling and fixtures meeting with different mounting method requirements
- Non-welded pipeline system
- Industrial control configuration software on LABVIEW
Working principle:
Put the cylinder into a water jacket and boost the cylinder by high pressure pump. It will automatically dwell at set pressure and do pressure test on the cylinder. At the same time, the cylinder valume expands under test pressure and squeezed some water from water jacket into the measuring cup, and it is test cylinder volume deformation. The water is transferred to PC by water collection system, the elastic deformation disappears after cylinder relief of pressure, then the water flows back from measuring cup to water jacket.However, the remainning water in the measuring cup is still more than that before boosting the cylinder. The extra water volume is the test gas cylinder volume residual deformation. While the gas cylinder volume residual deformation rate is the ratio of the test gas cylinder volume residual deformation to all deformation.
Note:
ing pressure: 40Mpa,
The actual test pressure control accuracy:no less than 10 psig
The actual water level measurement accuracy: no less than 0.4.
