Maintenance
Troubleshooting
If you hear the pump running but no pressure is building in the test cell:
1. Make sure the “Pressure Release Valve” is completely closed.
2. Make sure the “Air to Cylinder” valve is completely closed.
3. Make sure the “Fill Cell” valve is set to “Fill”.
4. The Consistometer has a rupture disk to prevent damage due to
overpressurization. If the pressure inside the cell exceeds 28,000 PSI,
the disk will rupture and release the pressure. If this happens, the cell
cannot be pressurized until the rupture disk has been replaced.
The rupture disk is located inside a square block just upstream from
the filter on the inlet side of the pump. To replace the rupture disk,
remove this block, discard the ruptured disk, and install a new disk.
Then re-install the block into the plumbing line.
When a test is complete, it should take several minutes to drain the test cell
of oil. If it takes more than an hour to completely drain the cell, the oil filter
between the cell and the reservoir may be dirty.
1.
Locate the oil filter near the top of the unit cabinet in the back. There
are two hex-shaped fittings. The smaller one on top is the air filter.
This one should never need maintenance. The larger one on bottom
is the oil filter.
2.
Before removing the fitting, observe the direction arrow on the side.
This will be important later when re-installing the filter.
3.
Carefully disconnect the pipe from the hex fitting.
4.
Remove the filter pieces from the hex fitting.
