The repeated expansion and contraction of air pockets within moving parts can lead to fatigue and premature wear. Over time, these tiny struggles accumulate, leading to significant performance degradation and ultimately, shortened lifespan.
This can manifest in decreased output, increased energy consumption, and increased maintenance requirements.
Impact on Pressure Regulation, Air in the lines causes what type of problem
Air pockets in lines disrupt the pressure regulation mechanisms. Their compressibility means they absorb pressure surges, leading to inconsistent pressure readings and potentially damaging effects on components designed for specific pressure ranges. This variability in pressure can cause unexpected fluctuations, impacting the accuracy and reliability of the system. In extreme cases, this can lead to equipment malfunction.
For example, a hydraulic press might not exert the required force due to pressure variations caused by air pockets.
Impact on Flow Rate
