Routine maintenance will ensure maximum life and trouble-free operation. While the maintenance schedule presented in this section is not rigid, modifications should be based on experience with operating the Mud Agitator at your facilities. A maintenance log should be kept to help establish a routine maintenance schedule, as well as to monitor and adjust the schedule as necessary throughout the equipment’s life. Consider the following factors when establishing a maintenance schedule:
• Duty cycle
• Ambient temperature
• Operating environment
ROUTINE MAINTENANCE
The following maintenance routine must be performed at least daily, or each shift if possible.
These activities may be performed while the degasser is operating.
The table below contains the recommended maintenance schedule for the drilling waste management . For
additional maintenance instructions such as troubleshooting and parts replacement, refer to the
manufacturer’s literature in Section 12 – Supplier Data.
Inspection
Clean and inspect motor approximately every 500 hours of operation or every 3 months,
whichever comes first, using the following procedure:
1. Clean the motor and ventilation openings. Check that motor interior and exterior are free of
dirt, oil, grease, water, or other contaminant. Proper ventilation prevents overheating and
premature failure.
2. Using a Megger, check insulation resistance of motor winding periodically, and immediately
investigate cause of any significant drop in insulation resistance.
3. Check that all electrical connections are secure.
Bearing Lubrication
The upper motor bearing should be lubricated every 12,000 hours. The following lubricants are
approved for motor lubrication:
Exxon Mobil Polyrex EM Pennzoil Pen 2 Lube RykonPremium #2
Texaco Polystar Chevron SRI
