Teikoku Electric Pump F300-8030A4BM-1214P1AV

TRG Bearing Wear Monitor Inspection

Check the TRG meter during operation

Determine bearing changing intervals using color coding system if initial TRG reading is not recorded

Check bearing wear using TRG meter color change

Is the TRG reading increase 0.3 or more (Yellow)?

Stop the pump and check bearings if TRG reading is Yellow

Do not operate if TRG meter condition is RED

Verify TRG meter is in Green zone (0 to 0.5)

Check that valves in reverse circulation piping are opened (for R & RA-type)

Meter overscale: Pump rotates in reverse direction — correct connection of electrical terminals

Set overload relay at rated current indicated on the nameplate

Ensure overload relay is set as close to actual operating conditions as possible

Confirm relay setting does not exceed the nameplate full load rating

Determine relay setting based on voltage & load variation

Confirm relay setting is applied during initial commissioning

Disconnect power cables to prevent safety hazards

Remove Circulation Pipe (34) or heat exchanger (B-type)

Insert support under Casing (01) to relieve stress from piping

Remove fixing Bolt (46B) or (46C) of Casing (01) for back pullout disassembly

Remove Bolt (46D) and slide pump backward on Base (40)

Measure the gap 'g' before further disassembling

Shaft Sleeve (17) and Thrust Collar (18) Inspection

Inspect shaft sleeve (17) for contact marks or wear

Inspect thrust collar (18) for contact marks or wear

Are there any other contact marks or wear?

Check sliding surface for luster and scratches
