Commissioning and Operation of the Compressor
Once the compressor is installed and the operating conditions confirmed, the valve configuration should be reviewed. If the current operating pressures are much different than the expected operating conditions, contact the Ariel Response Center (ARC) to confirm the valve configuration. Different springs may be necessary to ensure proper valve dynamic motion.
If the valve life proves shorter than expected, contact Ariel with the unit serial numbers, current valve part numbers and current operating conditions. The valve configuration can be confirmed, or altered as necessary.
A valve dynamic motion analysis can be provided for the valve design condition upon request. This is a mass spring damped motion review of the plate motion, including impact velocities and motion analysis. Response to the acoustical pulsations is not included in the valve motion study.
The current CP valve type is offered in one valve lift. This lower lift offers improved valve reliability, while maintaining or improving upon valve efficiency (flow area).
Older valve styles were offered in varying lift configurations to accommodate wider, or varying operating conditions. Low lift valves improved reliability by reducing impact stresses or improving closing timing. However, this also increased power usage, rod loads and discharge temperatures. The increase may be slight in most cases, but should be reviewed and considered.
Low lift valves were required when suction pressure, discharge pressure, and / or operating speed vary greater than 25%. Contact Ariel with the full range of operating conditions for review of valve type and lift.
