7.2 Inspection
Under normal operation the pump should be removed from the pit and inspected once
per year.
Under severe operating conditions where sand, fibrous material and solids are present
this should be done once per month.
The standard inspection procedure is summarized below.
7.2.1 Pump Removal
Loosen the bolts/nuts of the discharge piping so that the seal is broken.
Hook the lifting chain on the motor driven hoist or chain-block through the pump
lifting eye and support the load of the pump.
Remove the bolts/nuts of the discharge piping and lift the pump out of the well with
the hoist.
7.2.2 Inspection Procedure
7.2.2.1 Mechanical Seal
Check the resistance of mechanical seal sensor with Multi-Tester as shown
overleaf.
Do not use a Mega Tester.
This
will damage the control circuit.
7.2.2.2 Oil Replacement
After checking the resistance of seal sensor, replace the oil in the oil chamber.
First unscrew the oil inlet plug and tilt the pump towards the horizontal position
with the plug hole facing downwards in order to drain the oil.
If the drained oil is contaminated or opaque, this is indicative of impending
mechanical seal failure & the mechanical seal should be replaced.
Replace the oil with fresh oil injected through inlet oil plug hole.
