Leakage Testing Machine For Cover Cylinder Head

PRC has designed, developed & manufactured a dedicated air leakage testing machine for cover cylinder head which is unique in design. It is equipped with fixtures and other attachments with audio visual alarm for OK & NG.

Features of “Parametric” Leak Testing Machines:

• Highly accurate & dependable
• Quick leak detection
• Multi-channel operation
• Smart pneumatic & electronic circuits
• Easy calibration through Leak Masters.
• PC Interface through RS 232 C
• Pressure Decay leak measurements
• Strain gauge based pressure transducers / transmitters.

Theory of working:

The original dry-air method is pressure decay, in which the test part is pressurized and then isolated from the pressure source. Because air moves from a high-pressure area to a low-pressure area, any decrease in pressure indicates the presence of a leak. Algorithms then convert pressure changes into an approximation of the leak rate.
