Pressure Transmitters Used in Autofrettage
Fuel injector lines in diesel engines withstand an enormous amount of pressure cycling through them. There’s so much, in fact, that the lines will fatigue more quickly if they’re not treated. Autofrettage is the technique that treats fuel engine lines, making these thick-walled metal tubes more durable and resistant to wear. Pressure transmitters are a part of this process, used in autofrettage of fuel injectors as a part of detecting cracks and ruptures, hydraulic pressure control, and hydraulic pressure sensing
Autofrettage, which uses hydraulic systems monitored by pressure transmitters, doesn’t just treat fuel injector lines in diesel engines. The process is also commonly used in hydraulic cylinder manufacturing, LDPE production, oil field component manufacturing, and weapons manufacturing.
During the process:
Pressure transmitters control the pressure of the autofrettage hydraulic fluid, detect imperfections or failures during processing, and monitor and control automated processes to close and seal the connecting fixture.
The WIKA Pressure Transmitter for High Pressure Applications Type HP-2 is designed for superior performance in high-pressure applications such as autofrettage at up to 15,000 bar (217,550 psi) with long-term stability, high accuracy, and dynamic pressure curves.
The HP-2 offers:
