Overview of the Howden XRV 127 Series
Temporary fine-mesh suction strainers must be installed during initial commissioning to catch welding slag, pipe scale, and debris.
Measure bearing clearances. Journal and thrust bearings should be replaced proactively to prevent rotor-to-casing contact. howden xrv 127 manual
Use high-precision alignment tools across the flexible coupling.
Monitor suction pressure, discharge pressure, oil pressure, and discharge temperature. Vibration: Listen for unusual noise or high vibration. 5.2 Scheduled Maintenance Accessing and understanding the technical manual for the
Oil-flooded, utilizing differential pressure for lubrication while running. Bearings: Cylindrical roller bearings support both rotors. Compatible Refrigerants: Ammonia ( NH3cap N cap H sub 3 , R-717) and Halocarbons (Freon). Speed Control: Suitable for inverter (VFD) speed control. 3. Installation and Pre-commissioning Guidelines
