What action should be taken immediately if a compressor shows signs of hydraulic pounding?

When a compressor exhibits signs of hydraulic pounding, the immediate course of action should indeed be to shut it down and call for assistance. Hydraulic pounding typically indicates a serious operational issue, often related to liquid slugs entering the compressor, which can lead to significant mechanical failures or damage. By shutting down the compressor, you prevent the risk of worsening the situation or causing extensive damage, both to the compressor and potentially to other connected systems.

Calling for assistance is crucial because diagnosing and rectifying the problem often requires specialized knowledge and tools. Hydraulic pounding is not a condition that can be safely adjusted or resolved while the compressor is still operating. It is essential to involve experts who can assess the situation properly and implement the necessary repairs or maintenance. This approach prioritizes safety and equipment integrity over attempting to continue operations, which could lead to catastrophic failures and greater costs.
