Applications in Gas Cylinder Fatigue Testing Machines

　　The primary principle of the plunger‑pump cylinder fatigue testing system is to use high‑pressure water to generate hydraulic pulse loading inside gas cylinders and steel cylinders, thereby evaluating their resistance to pulse‑induced fatigue. The equipment also enables precise control of ambient and fluid temperatures.

　　Test results are automatically saved, and both Chinese and English versions of the report are generated. Users can query historical trend curves and data reports, print output, and monitor high-pressure gauges via video. In the event of a fault, an alarm is triggered, making this system ideal for unattended operation.

PRINCIPLE Meijie – Advantages of the Plunger Pump Fatigue Testing Machine

• The maximum pressure can reach 280 MPa, not only meeting the requirements of the most stringent cylinder fatigue tests but also supporting burst‑test applications, offering multi‑functionality in a single unit.
• The medium is water, and its use is environmentally friendly with zero pollution.
• Users can replace wear parts themselves; the replacement takes just over 10 minutes.
• Pressure and flow can be freely switched by replacing the stuffing box assembly, offering convenience and speed.
• Wide temperature range, remote operation and monitoring capabilities, and no personnel safety risks.
• It enables real-time display of data and waveforms, as well as retrieval of historical data for any node.
• Wear parts have a long service life, offering better value for money with each replacement.
