Helium lines remain under high pressure even when the unit is turned off. Never attempt to disconnect lines without verifying that self-sealing couplings are fully functional.
To ensure safe and efficient operation, follow these general guidelines:
Mount the compressor on a level, vibration-free surface. Tilting the unit can cause the oil separator to fail, leading to oil migration into the cryopump.
Check the self-sealing Aeroquip couplings for dust, debris, or damage. sumitomo f50 compressor manual
What of the F-50 do you have (e.g., F-50H, F-50L)?
Verify that the front-panel helium pressure gauge aligns with manual recommendations. 4. Maintenance Schedules and Procedures
The Sumitomo F50 operates with high-pressure helium gas and electrical components, making strict adherence to safety guidelines mandatory. Helium lines remain under high pressure even when
The adsorber removes trace oil vapors from the helium stream. Failing to replace it on schedule leads to oil migration into the cold head, freezing the matrix and halting the cryopump.
The pressure when the system is completely stopped and at room temperature (typically around 1.6 to 1.7 MPa, varying slightly by ambient temperature). Operating Pressure:
When you find it, expect sections on:
Do not use a for F50R (refrigeration) if yours is an air compressor – oil management and safety valves are different. Confirm the application on the nameplate before following any torque or pressure settings.
Always use two wrenches (one to hold the body, one to turn the union nut) to prevent twisting the internal copper lines. Tighten until hard up, then add a 1/4 turn. 3. Standard Operating Procedures Pre-Start Checklist
The Sumitomo F50 is a rotary screw compressor that is known for its reliability and efficiency. Here are a few options to help you obtain a manual: Tilting the unit can cause the oil separator
