Daily/Weekly Maintenance Checklist
1. Check overall condition of main Centrifugal skid for damage or welding cracks X X
2. Check overall condition of all Vibration mounts to foundation. X X
3. Check pump for noisy bearings and cavitation. X X
4. Check bearing oil for water and discoloration. X X
5. Feel all bearings for temperature. X X
6. Check oil leaks at the gaskets. X X
7. Self-flush pumps – Hand check the flush line temperature to determine flow through the line. X X
8. External flush pumps – Determine if flow indicator and needle valve adjustment are functioning properly. X X
9. Determine if the mechanical seal conditions are normal. X X
10. Check any water cooling for effective operation. Hand test differential across coolers, jackets and exchangers. Disassemble and clean as required. X X
11. Check the operation of the heat tracing. X X
12. Determine if steam leakage at packing and glands is normal. X X
13. Check for leaks at pressure casing and gaskets. Determine if steam traps are operating properly – no continuous blow & water X X
in casing or drain.
Monthly Checklist
1. Add oil to the bearing reservoirs, if required. X
2. Clean oiler bulbs and level windows as required. X
3. Make sure that the oil level is the correct distance from the shaft centerline. Adjust if necessary. X
4. Clean out debris from bearing brackets. Drain hole must be open. X
5. Change oil in hydraulic governors. X
6. Determine if hydraulic governor heater is working. X
7. Check for proper oil level & leaks at hydraulic governor. Check for oil leaks at lines, fittings & power piston. X
8. Replace guards (repair if required). X
9. Determine if pump unit requires general cleaning by others. X
6-Month Checklist Note: Check for any metal particles on magnetic plugs when checking oil
1. Overfill bearing housing to bottom of the shaft and rotate several turns by hand to coat the shaft and the bearing with oil. X
(Machine not running) X
2. Apply a light coat of rust preventive product to expose machined surfaces to prevent rust and corrosion. X
3. Clean & oil governor linkage & valve stems. X
4. Exercise overspeed trip & valve steam linkage on turbines not running. X
Yearly Checklist
1. Thoroughly inspect disc coupling for signs of wear & cracks in lamination. Tighten bolts. X
2. Using a dial indicator, check the coupling alignment with the equipment coupled. Use special coupling indicator clamps where X
possible. Ensure that thermal growth allowance is correct. X
3. Using an indicator clamped on the coupling, depress and lift on each coupling and note the dial indicator change. Determine if the X
deflection is normal for this machine. Refer to OEM manual. X
4. Inspect trip and throttle valve stems and their linkages for wear. Check over-speed mechanism for wear. X
5. Remove mechanical the governor cover & inspect flyball seat, spring, bearing & plunger for wear. X
6. Remove turbine sentinel valve. Shop test & adjust to proper setting. X
7. Adjust trip mechanism & repeat procedure. Follow manufacturer’s instructions when making adjustments. X
8. Verify proper governor operation & control. Determine if hand (booster) valves are completely closed when required to carry load. X
Note: If major refurbishment is required all components to be removed for blasting and painting
