PURIFIER INSPECTION

PURIFIER FEED PUMP

1)      Running Amps
2)      Motor temperature by hand
3)      Shaft seal leaking?
4)      Pump lubricator
5)      Pump suction & discharge pressures (suction filter blocked?)
6)      Valve glands for leaks and any other pipe joint leaks

HEATER

1)      Temperature controller set point and feed back temperature
2)      Check temperature controller supply air for water
3)      Local temperature inlet and outlet
4)      Oil leaks/steam leaks
5)      Relief valve
6)      Steam supply valve position

PURIFIER

1)      Motor amps
2)      Motor temperature by hand and vibrations
3)      Observe drive belt through observation window
4)      Separator oil level
5)      Observe Separator flow (in 24 hours to circulate and separate all sump oil)
6)      Back pressure (1.5 to 2 bar)
7)      Lube oil inlet temperature (90 Deg C)
8)      Inspect hoses and pipes
9)      If appropriate check operating water pulse signal
10)  Check de-sludge timer (countdown on Main control panel) and if safe to do so, remove the sludge outlet inspection plug to ensure no flow is present from water and solids discharges
11)  Manually de-sludge Separator to ensure correct operation. Ensure 3 way valve changes and Separator flow reduces to zero. Monitor displacement water is added by checking the operating water chamber solenoid valve operation and a sharp crack sound should be heard for ejection. Look at Separator amps for “ejection monitoring” and speed recovery. Check for filling water operation. Ensure Separator comes back on line.
