1.01.002 Electric Drive PM

This Policy is completed waiting on Field Service, Engineering, & Safety approval.

Purpose

The purpose of this procedure is to establish the minimum requirements for performing scheduled Preventative Maintenance (PM) on Flogistix Electric Drive units and to ensure compressor / driver longevity by maintaining Flogistix units as described in this procedure. Maintenance intervals shall be based on run time hours of 2,190 running hours or driver manufacturer's recommended time intervals, whichever is less. Preventative Maintenance hours will be tracked automatically by Flogistix. Flogistix maintenance activities will vary depending on unit type, but will not exceed 2,190 run hours.

Procedure

This procedure applies to all units that are currently in service in the field, at a repair shop, and in storage yards. Flogistix Service Technicians will perform the scheduled PM as required according to the type of compressor unit being maintained.

Before any work is performed, a JSA must be completed according to Flogistix procedure along with any Customer requirements before any work is started.

Preventative Maintenance Pre-Check items of unit before shutdown:

1. Compressor Skid

   1. Check over unit for leaks, abnormal noises or vibrations

   2. Check make-up / recycle system for proper setting and operation (if applicable)

   3. Check all Pressure Relief Valves (PRV) for current/correct pressure tags and wire seals, rain caps on exhaust piping of PR 1.1.2 Pressure Relief Valves (PRV)

   4. Control & Safety Shutdown Devices

      1. Test all Safety Shutdowns 1.02.005 Check Shutdown Devices

   5. Check Inlet Scrubber dump controls for proper operation

   6. Check all guards and brackets, ensuring they are in place, secure, and undamaged

   7. Check differential pressures on filters in Suction/Inlet Vessel and Discharge Vessel

   8. Check Telemetry (if applicable)

• • 1. Check antennas for proper cable connections and tight seal against control panel enclosure

    2. Check cell modem for power and communication lights are all green . 1.07.021 LOGIX panel - Installation of Sierra Wireless RV50

2. Electric Drive Motor and Cooling Fan Motor:

• 1. Check for abnormal vibration or noise

  2. Check that there is air flow from motor fan

  3. Visually check to make sure all electrical conduit going to motor is tight

  4. Visually check electrical cable/flex conduit going to motors for any wear or damage

3. Screw Compressor:

• 1. Check Scavenge Line & needle valve for efficient flow 1.6.2 Scavenge Line Adjustment

  2. Check discharge temperature of compressor oil to make sure temperature is above gas dew point

  3. Check screw compressor oil level in Discharge Vessel while unit is running at operating conditions

  4. Take oil sample of compressor (if applicable)

4. Reciprocating Compressor applications:

• 1. Check inter-stage pressures for failed compressor valves and/or piston rings

  2. Check cylinder discharge temperatures for failed compressor valves

  3. Check for warm suction valve caps on each cylinder

  4. Check lubricator box oil level

  5. Check lubricator pump for proper lubrication to cylinders

  6. Check packing vents for leaking gas vapors

Before any work is performed all Safety precautions and LOTO must be in-place according to Flogistix policy on the unit type for Preventative Maintenance.

Preventative Maintenance items to be performed after shutdown of unit

1. Electric Drive Motor items: Electric Motors require minimal scheduled maintenance

   1. Motor bearings should be greased with Mobile XHP 222 type grease or equivalent. If adding grease to the motor bearings only add one pump of grease from a grease gun to each motor bearing. Grease should not be added to the bearings between the 90 day scheduled maintenance period. It is better for electric motors to be under greased than to have too much grease added to the bearings.

2. Screw Compressor items:

• 1. Change compressor oil spin on filter(s) 1.4.1 Compressor Oil Filter Change

  2. Check compressor oil for dilution or mixing with condensate

  3. Check compressor oil viscosity

  4. Add or replace compressor oil to proper level in discharge vessel.

  5. Clean Scavenge line sightglass if needed

3. Reciprocating Compressor items:

• 1. Change compressor oil spin on filter

  2. Check piston rod(s) for wear

  3. Visually check packing glands and packing tubing lines

  4. Visually check drive coupling for cracked shims or wear

4. Cooler items:

• 1. Check Fan belts Electric motor driven (if applicable) (replace as needed)

  2. Check Cooler louvers (if applicable)

  3. Check Cooler frame and fan supports for cracks

  4. Check cooler grease lines (if applicable)

5. Panel items:

• 1. Check panel for loose terminal & wire connections

  2. Check and clean cabinet air filters on VFD cabinet

Preventative Maintenance items to be done after Re-Starting the compressor unit.

1. Electric Drive Motor

   1. Check Electric drive motor for any abnormal noise or vibration

2. Screw Compressor

• 1. Check Compressor Oil level

  2. Adjust Scavenge Line needle valve for efficient flow 1.06.002 Scavenge Line Adjustment

  3. Check spin on filter differential pressure 1.07.030 LOGIX panel - Setting up proper Compressor Oil Filter Differential Pressure

  4. Check differential pressure between suction and discharge pressure for proper Delta P to maintain oil flow to compressor

3. Cooler

• 1. Grease Cooler bearings and Idler bearings

  2. Check for air flow across cooler sections

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.
