Section 3 – Maintenance
This section describes the basic maintenance that is required for the 5265
Autoclaves. A troubleshooting guide is also provided in the event that a problem
occurs.
Maintenance
The 5265 Autoclave requires very little routine maintenance. Following the
recommendations listed below will allow years of trouble free operation.
Tools Required
• 5/8" wrench
• 9/64" hex wrench
• Teflon tape
• Screwdriver
• Bench vise
.
Cleaning and Service Tips
• Keep all test cell surfaces exposed to cement coated with a thin layer of
grease. This reduces the chance of corrosion and prevents cement from
adhering to the metal.
• Keep cement off threads and out of the high-pressure ports on the top plug
of the test cell.
• Lubricate the threads on the test cell plugs periodically with anti-seize
lubricant.
• Thoroughly clean test cell of all cement immediately after each test.
• Keep the sensor faces and cavities inside each test cell plug clean and flat.
• Always apply a thin layer of acoustic couplant to the sensor after it has been
removed.
• Always recheck the transit time, using the cal bar, after cleaning the sensor
and replacing the couplant.
Calibration Procedure
The temperature controller may require periodic calibration after extended use.
The procedures related to calibrating the controller are found in the Model
7050/7051 controller manual.
The instrument does not require calibration for the measurement of static gel
strength. The values measured are absolute and there are no user accessible
adjustments.
The measurement of transit time requires periodic calibration to ensure accurate
measurements. The procedure is listed as follows:
