RISK ASSESSMENT FOR TESTING AND COMMISSIONING OF CHILLED WATER PUMPS

 

RISK ASSESSMENT FOR TESTING AND COMMISSIONING OF CHILLED WATER PUMPS
RISK ASSESSMENT FOR TESTING AND COMMISSIONING OF CHILLED WATER PUMPS

HSE Documents Ensuring a chilled water system functions efficiently and reliably relies on the proper testing and commissioning of its pumps. This process verifies the pump's performance meets design specifications and identifies any potential issues before full operation. It typically involves pre-commissioning checks, operational testing, and performance monitoring. Pre-commissioning ensures correct installation, cleanliness, and proper rotation of pump components. 

Operational testing involves starting the pump with closed discharge valves, recording pressure readings as valves open, and monitoring for overheating vibration, and motor performance. Finally, performance is compared to pump curves to confirm flow and pressure meet design requirements. This systematic approach safeguards the chilled water system's integrity and optimizes its overall efficiency
